Overview and features -======================== -This driver supports the video interface of the devices mounting the ET61X151 -or ET61X251 PC Camera Controllers. - -It's worth to note that Etoms Electronics has never collaborated with the -author during the development of this project; despite several requests, -Etoms Electronics also refused to release enough detailed specifications of -the video compression engine. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ET61X[12]51 driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1 and 2 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - paragraph); -- full support for the capabilities of every possible image sensors that can - be connected to the ET61X[12]51 bridges, including, for istance, red, green, - blue and global gain adjustments and exposure control (see "Supported - devices" paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both ET61X[12]51 and image sensor control (see - "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_ET61X251=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "et61x251" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe et61x251 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some more informations - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the ET61X[12]51 and the image sensor -registers by using the "sysfs" filesystem interface. - -There are four files in the /sys/class/video4linux/videoX directory for each -registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files -control the ET61X[12]51 bridge, while the other two control the sensor chip. -"reg" and "i2c_reg" hold the values of the current register index where the -following reading/writing operations are addressed at through "val" and -"i2c_val". Their use is not intended for end-users, unless you know what you -are doing. Remember that you must be logged in as root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that if the sensor registers can not be read, "cat" will fail. -To avoid race conditions, all the I/O accesses to the files are serialized. - - -9. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers.

Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1 and 2 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The current compression quality may vary from 0 to 1 and can -be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP -V4L2 ioctl's. - - -11.

See http://www.xirlink.com/ -(renamed to http://www.veo.com), http://www.ibmpccamera.com, -or http://www.c-itnow.com/ for details and pictures. - -This very chipset ("X Chip", as marked at the factory) -is used in several other cameras, and they are supported -as well: - -- IBM NetCamera -- Veo Stingray - -The Linux driver was developed with camera with following -model number (or FCC ID): KSX-XVP510. This camera has three -interfaces, each with one endpoint (control, iso, iso). This -type of cameras is referred to as "model 1". These cameras are -no longer manufactured. - -Xirlink now manufactures new cameras which are somewhat different. -In particular, following models [FCC ID] belong to that category: - -XVP300 [KSX-X9903] -XVP600 [KSX-X9902] -XVP610 [KSX-X9902] - -(see http://www.xirlink.com/ibmpccamera/ for updates, they refer -to these new cameras by Windows driver dated 12-27-99, v3005 BETA) -These cameras have two interfaces, one endpoint in each (iso, bulk). -Such type of cameras is referred to as "model 2". They are supported -(with exception of 352x288 native mode). - -Some IBM NetCameras (Model 4) are made to generate only compressed -video streams. This is great for performance, but unfortunately -nobody knows how to decompress the stream :-( Therefore, these -cameras are *unsupported* and if you try to use one of those, all -you get is random colored horizontal streaks, not the image! -If you have one of those cameras, you probably should return it -to the store and get something that is supported. - -Tell me more about all that "model" business --------------------------------------------- - -I just invented model numbers to uniquely identify flavors of the -hardware/firmware that were sold. It was very confusing to use -brand names or some other internal numbering schemes. So I found -by experimentation that all Xirlink chipsets fall into four big -classes, and I called them "models". Each model is programmed in -its own way, and each model sends back the video in its own way. - -Quirks of Model 2 cameras: -------------------------- - -Model 2 does not have hardware contrast control. Corresponding V4L -control is implemented in software, which is not very nice to your -CPU, but at least it works. - -This driver provides 352x288 mode by switching the camera into -quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting -this mode to 10 frames per second or less, in ideal conditions on -the bus (USB is shared, after all). The frame rate -has to be programmed very conservatively. Additional concern is that -frame rate depends on brightness setting; therefore the picture can -be good at one brightness and broken at another! I did not want to fix -the frame rate at slowest setting, but I had to move it pretty much down -the scale (so that framerate option barely matters). I also noticed that -camera after first powering up produces frames slightly faster than during -consecutive uses. All this means that if you use 352x288 (which is -default), be warned - you may encounter broken picture on first connect; -try to adjust brightness - brighter image is slower, so USB will be able -to send all data. However if you regularly use Model 2 cameras you may -prefer 176x144 which makes perfectly good I420, with no scaling and -lesser demands on USB (300 Kbits per second, or 26 frames per second). - -Another strange effect of 352x288 mode is the fine vertical grid visible -on some colored surfaces. I am sure it is caused by me not understanding -what the camera is trying to say. Blame trade secrets for that. - -The camera that I had also has a hardware quirk: if disconnected, -it needs few minutes to "relax" before it can be plugged in again -(poorly designed USB processor reset circuit?) - -[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't -observed this particular flaw in it.] - -Model 2 camera can be programmed for very high sensitivity (even starlight -may be enough), this makes it convenient for tinkering with. The driver -code has enough comments to help a programmer to tweak the camera -as s/he feels necessary. - -WHAT YOU NEED: - -- A supported IBM PC (C-it) camera (model 1 or 2) - -- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work) - -- A Video4Linux compatible frame grabber program such as xawtv. - -HOW TO COMPILE THE DRIVER: - -You need to compile the driver only if you are a developer -or if you want to make changes to the code. Most distributions -precompile all modules, so you can go directly to the next -section "HOW TO USE THE DRIVER". - -The ibmcam driver uses usbvideo helper library (module), -so if you are studying the ibmcam code you will be led there. - -The driver itself consists of only one file in usb/ directory: -ibmcam.c. This file is included into the Linux kernel build -process if you configure the kernel for CONFIG_USB_IBMCAM. -Run "make xconfig" and in USB section you will find the IBM -camera driver. Select it, save the configuration and recompile. - -HOW TO USE THE DRIVER: - -I recommend to compile driver as a module. This gives you an -easier access to its configuration. The camera has many more -settings than V4L can operate, so some settings are done using -module options. - -To begin with, on most modern Linux distributions the driver -will be automatically loaded whenever you plug the supported -camera in. Therefore, you don't need to do anything. However -if you want to experiment with some module parameters then -you can load and unload the driver manually, with camera -plugged in or unplugged. - -Typically module is installed with command 'modprobe', like this: - -# modprobe ibmcam framerate=1 - -Alternatively you can use 'insmod' in similar fashion: - -# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1 - -Module can be inserted with camera connected or disconnected. - -The driver can have options, though some defaults are provided. - -Driver options: (* indicates that option is model-dependent) - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -debug Integer 0-9 [0] debug=1 -flags Integer 0-0xFF [0] flags=0x0d -framerate Integer 0-6 [2] framerate=1 -hue_correction Integer 0-255 [128] hue_correction=115 -init_brightness Integer 0-255 [128] init_brightness=100 -init_contrast Integer 0-255 [192] init_contrast=200 -init_color Integer 0-255 [128] init_color=130 -init_hue Integer 0-255 [128] init_hue=115 -lighting Integer 0-2* [1] lighting=2 -sharpness Integer 0-6* [4] sharpness=3 -size Integer 0-2* [2] size=1 - -Options for Model 2 only: - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -init_model2_rg Integer 0..255 [0x70] init_model2_rg=128 -init_model2_rg2 Integer 0..255 [0x2f] init_model2_rg2=50 -init_model2_sat Integer 0..255 [0x34] init_model2_sat=65 -init_model2_yb Integer 0..255 [0xa0] init_model2_yb=200 - -debug You don't need this option unless you are a developer. - If you are a developer then you will see in the code - what values do what. 0=off. - -flags This is a bit mask, and you can combine any number of - bits to produce what you want. Usually you don't want - any of extra features this option provides: - - FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed - VIDIOCSYNC ioctls without failing. - Will work with xawtv, will not - with xrealproducer. Default is - not set. - FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode. - FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have - magic meaning to developers. - FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen, - useful only for debugging. - FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers. - FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as - it was received from the camera. - Default (not set) is to mix the - preceding frame in to compensate - for occasional loss of Isoc data - on high frame rates. - FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame - prior to use; relevant only if - FLAGS_SEPARATE_FRAMES is set. - Default is not to clean frames, - this is a little faster but may - produce flicker if frame rate is - too high and Isoc data gets lost. - FLAGS_NO_DECODING 128 This flag turns the video stream - decoder off, and dumps the raw - Isoc data from the camera into - the reading process. Useful to - developers, but not to users. - -framerate This setting controls frame rate of the camera. This is - an approximate setting (in terms of "worst" ... "best") - because camera changes frame rate depending on amount - of light available. Setting 0 is slowest, 6 is fastest. - Beware - fast settings are very demanding and may not - work well with all video sizes. Be conservative. - -hue_correction This highly optional setting allows to adjust the - hue of the image in a way slightly different from - what usual "hue" control does. Both controls affect - YUV colorspace: regular "hue" control adjusts only - U component, and this "hue_correction" option similarly - adjusts only V component. However usually it is enough - to tweak only U or V to compensate for colored light or - color temperature; this option simply allows more - complicated correction when and if it is necessary. - -init_brightness These settings specify _initial_ values which will be -init_contrast used to set up the camera. If your V4L application has -init_color its own controls to adjust the picture then these -init_hue controls will be used too. These options allow you to - preconfigure the camera when it gets connected, before - any V4L application connects to it. Good for webcams. - -init_model2_rg These initial settings alter color balance of the -init_model2_rg2 camera on hardware level. All four settings may be used -init_model2_sat to tune the camera to specific lighting conditions. These -init_model2_yb settings only apply to Model 2 cameras. - -lighting This option selects one of three hardware-defined - photosensitivity settings of the camera. 0=bright light, - 1=Medium (default), 2=Low light. This setting affects - frame rate: the dimmer the lighting the lower the frame - rate (because longer exposition time is needed). The - Model 2 cameras allow values more than 2 for this option, - thus enabling extremely high sensitivity at cost of frame - rate, color saturation and imaging sensor noise. - -sharpness This option controls smoothing (noise reduction) - made by camera. Setting 0 is most smooth, setting 6 - is most sharp. Be aware that CMOS sensor used in the - camera is pretty noisy, so if you choose 6 you will - be greeted with "snowy" image. Default is 4. Model 2 - cameras do not support this feature. - -size This setting chooses one of several image sizes that are - supported by this driver. Cameras may support more, but - it's difficult to reverse-engineer all formats. - Following video sizes are supported: - - size=0 128x96 (Model 1 only) - size=1 160x120 - size=2 176x144 - size=3 320x240 (Model 2 only) - size=4 352x240 (Model 2 only) - size=5 352x288 - size=6 640x480 (Model 3 only) - - The 352x288 is the native size of the Model 1 sensor - array, so it's the best resolution the camera can - yield. The best resolution of Model 2 is 176x144, and - larger images are produced by stretching the bitmap. - Model 3 has sensor with 640x480 grid, and it works too, - but the frame rate will be exceptionally low (1-2 FPS); - it may be still OK for some applications, like security. - Choose the image size you need. The smaller image can - support faster frame rate. Default is 352x288. - -For more information and the Troubleshooting FAQ visit this URL: - - http://www.linux-usb.org/ibmcam/ - -WHAT NEEDS TO BE DONE: - -- The button on the camera is not used. I don't know how to get to it. - I know now how to read button on Model 2, but what to do with it? - -- Camera reports its status back to the driver; however I don't know - what returned data means. If camera fails at some initialization - stage then something should be done, and I don't do that because - I don't even know that some command failed. This is mostly Model 1 - concern because Model 2 uses different commands which do not return - status (and seem to complete successfully every time). - -- Some flavors of Model 4 NetCameras produce only compressed video - streams, and I don't know how to decode them. - -CREDITS: - -The code is based in no small part on the CPiA driver by Johannes Erdfelt, -Randy Dunlap, and others. Big thanks to them for their pioneering work on that -and the USB stack. - -I also thank John Lightsey for his donation of the Veo Stingray camera. diff --git a/Documentation/usb/ov511.txt b/Documentation/usb/ov511.txt deleted file mode 100644 index a7fc043..0000000 --- a/Documentation/usb/ov511.txt +++ /dev/null @@ -1,289 +0,0 @@ -------------------------------------------------------------------------------- -Readme for Linux device driver for the OmniVision OV511 USB to camera bridge IC -------------------------------------------------------------------------------- - -Author: Mark McClelland -Homepage: http://alpha.dyndns.org/ov511 - -INTRODUCTION: - -This is a driver for the OV511, a USB-only chip used in many "webcam" devices. -Any camera using the OV511/OV511+ and the OV6620/OV7610/20/20AE should work. -Video capture devices that use the Philips SAA7111A decoder also work.

This feature is not yet implemented. - - NAME: autoexp - TYPE: integer (Boolean) - DEFAULT: 1 - DESC: Auto Exposure Control enable. This feature is not yet implemented. - - NAME: debug - TYPE: integer (0-6) - DEFAULT: 3 - DESC: Sets the threshold for printing debug messages. The higher the value, - the more is printed. The levels are cumulative, and are as follows: - 0=no debug messages - 1=init/detection/unload and other significant messages - 2=some warning messages - 3=config/control function calls - 4=most function calls and data parsing messages - 5=highly repetitive mesgs - - NAME: snapshot - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set to 1 to enable snapshot mode. read()/VIDIOCSYNC will block until - the snapshot button is pressed. Note: enabling this mode disables - /proc/video/ov511//button - - NAME: cams - TYPE: integer (1-4 for OV511, 1-31 for OV511+) - DEFAULT: 1 - DESC: Number of cameras allowed to stream simultaneously on a single bus. - Values higher than 1 reduce the data rate of each camera, allowing two - or more to be used at once. If you have a complicated setup involving - both OV511 and OV511+ cameras, trial-and-error may be necessary for - finding the optimum setting. - - NAME: compress - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set this to 1 to turn on the camera's compression engine. This can - potentially increase the frame rate at the expense of quality, if you - have a fast CPU. You must load the proper compression module for your - camera before starting your application (ov511_decomp or ov518_decomp). - - NAME: testpat - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: This configures the camera's sensor to transmit a colored test-pattern - instead of an image. This does not work correctly yet. - - NAME: dumppix - TYPE: integer (0-2) - DEFAULT: 0 - DESC: Dumps raw pixel data and skips post-processing and format conversion. - It is for debugging purposes only. Options are: - 0: Disable (default) - 1: Dump raw data from camera, excluding headers and trailers - 2: Dumps data exactly as received from camera - - NAME: led - TYPE: integer (0-2) - DEFAULT: 1 (Always on) - DESC: Controls whether the LED (the little light) on the front of the camera - is always off (0), always on (1), or only on when driver is open (2). - This is not supported with the OV511, and might only work with certain - cameras (ones that actually have the LED wired to the control pin, and - not just hard-wired to be on all the time). - - NAME: dump_bridge - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system - log. Only useful for serious debugging/development purposes. - - NAME: dump_sensor - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the sensor register values to the system log. Only useful for - serious debugging/development purposes. - - NAME: printph - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This - is only useful if you are trying to debug problems with the isoc data - stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be - warned that this dumps a large number of messages to your kernel log. - - NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv - TYPE: integer (0-63 for phy and phuv, 0-255 for rest) - DEFAULT: OV511 default values - DESC: These are registers 70h - 77h of the OV511, which control the - prediction ranges and quantization thresholds of the compressor, for - the Y and UV channels in the horizontal and vertical directions. See - the OV511 or OV511+ data sheet for more detailed descriptions. These - normally do not need to be changed. - - NAME: lightfreq - TYPE: integer (0, 50, or 60) - DEFAULT: 0 (use sensor default) - DESC: Sets the sensor to match your lighting frequency. This can reduce the - appearance of "banding", i.e. horizontal lines or waves of light and - dark that are often caused by artificial lighting. Valid values are: - 0 - Use default (depends on sensor, most likely 60 Hz) - 50 - For European and Asian 50 Hz power - 60 - For American 60 Hz power - - NAME: bandingfilter - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enables the sensor´s banding filter exposure algorithm. This reduces - or stabilizes the "banding" caused by some artificial light sources - (especially fluorescent). You might have to set lightfreq correctly for - this to work right. As an added bonus, this sometimes makes it - possible to capture your monitor´s output. - - NAME: fastset - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Allows picture settings (brightness, contrast, color, and hue) to take - effect immediately, even in the middle of a frame. This reduces the - time to change settings, but can ruin frames during the change. Only - affects OmniVision sensors. - - NAME: force_palette - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Forces the palette (color format) to a specific value. If an - application requests a different palette, it will be rejected, thereby - forcing it to try others until it succeeds. This is useful for forcing - greyscale mode with a color camera, for example. Supported modes are: - 0 (Allows all the following formats) - 1 VIDEO_PALETTE_GREY (Linear greyscale) - 10 VIDEO_PALETTE_YUV420 (YUV 4:2:0 Planar) - 15 VIDEO_PALETTE_YUV420P (YUV 4:2:0 Planar, same as 10) - - NAME: backlight - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this flag changes the exposure algorithm for OmniVision sensors - such that objects in the camera's view (i.e. your head) can be clearly - seen when they are illuminated from behind. It reduces or eliminates - the sensor's auto-exposure function, so it should only be used when - needed. Additionally, it is only supported with the OV6620 and OV7620. - - NAME: unit_video - TYPE: Up to 16 comma-separated integers - DEFAULT: 0,0,0... (automatically assign the next available minor(s)) - DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices. - For example, "unit_video=1,3" will make the driver use /dev/video1 and - /dev/video3 for the first two devices it detects. Additional devices - will be assigned automatically starting at the first available device - node (/dev/video0 in this case). Note that you cannot specify 0 as a - minor number. This feature requires kernel version 2.4.5 or higher. - - NAME: remove_zeros - TYPE: integer (Boolean) - DEFAULT: 0 (do not skip any incoming data) - DESC: Setting this to 1 will remove zero-padding from incoming data. This - will compensate for the blocks of corruption that can appear when the - camera cannot keep up with the speed of the USB bus (eg. at low frame - resolutions). This feature is always enabled when compression is on. - - NAME: mirror - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This - might be necessary if your camera has a custom lens assembly. This has - no effect with video capture devices. - - NAME: ov518_color - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enable OV518 color support. This is off by default since it doesn't - work most of the time. If you want to try it, you must also load - ov518_decomp with the "nouv=0" parameter. If you get improper colors or - diagonal lines through the image, restart your video app and try again. - Repeat as necessary. - -WORKING FEATURES: - o Color streaming/capture at most widths and heights that are multiples of 8. - o Monochrome (use force_palette=1 to enable) - o Setting/getting of saturation, contrast, brightness, and hue (only some of - them work the OV7620 and OV7620AE) - o /proc status reporting - o SAA7111A video capture support at 320x240 and 640x480 - o Compression support - o SMP compatibility - -HOW TO CONTACT ME: - -You can email me at mark@alpha.dyndns.org .

Overview and features -======================== -This driver attempts to support the video interface of the devices mounting the -SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers. - -It's worth to note that SONiX has never collaborated with the author during the -development of this project, despite several requests for enough detailed -specifications of the register tables, compression engine and video data format -of the above chips. Nevertheless, these informations are no longer necessary, -becouse all the aspects related to these chips are known and have been -described in detail in this documentation. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the SN9C10x driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for built-in microphone interface; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - and "Video frame formats" paragraphs); -- full support for the capabilities of many of the possible image sensors that - can be connected to the SN9C10x bridges, including, for istance, red, green, - blue and global gain adjustments and exposure (see "Supported devices" - paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both SN9C10x and image sensor control and - monitoring (see "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -The SN9C103 controller also provides a built-in microphone interface. It is -supported by the USB Audio driver thanks to the ALSA API: - - # Sound - # - CONFIG_SOUND=y - - # Advanced Linux Sound Architecture - # - CONFIG_SND=m - - # USB devices - # - CONFIG_SND_USB_AUDIO=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_SN9C102=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "sn9c102" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe sn9c102 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - recognized camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used. It also shows some more informations about the - hardware being detected. This parameter can be changed at - runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" [1] -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the SN9C10x and the image sensor -registers by using the "sysfs" filesystem interface. - -Every time a supported device is recognized, a write-only file named "green" is -created in the /sys/class/video4linux/videoX directory. You can set the green -channel's gain by writing the desired value to it. The value may range from 0 -to 15 for SN9C101 or SN9C102 bridges, from 0 to 127 for SN9C103 bridges. -Similarly, only for SN9C103 controllers, blue and red gain control files are -available in the same directory, for which accepted values may range from 0 to -127. - -There are other four entries in the directory above for each registered camera: -"reg", "val", "i2c_reg" and "i2c_val". The first two files control the -SN9C10x bridge, while the other two control the sensor chip. "reg" and -"i2c_reg" hold the values of the current register index where the following -reading/writing operations are addressed at through "val" and "i2c_val". Their -use is not intended for end-users. Note that "i2c_reg" and "i2c_val" will not -be created if the sensor does not actually support the standard I2C protocol or -its registers are not 8-bit long. Also, remember that you must be logged in as -root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that "cat" will fail if sensor registers cannot be read. - -Now let's set the green gain's register of the SN9C101 or SN9C102 chips to 2: - - [root@localhost #] echo 0x11 > reg - [root@localhost #] echo 2 > val - -Note that the SN9C10x always returns 0 when some of its registers are read. -To avoid race conditions, all the I/O accesses to the above files are -serialized. - -The sysfs interface also provides the "frame_header" entry, which exports the -frame header of the most recent requested and captured video frame.

Non-available hardware will not be supported by the author of this -driver. - - -10. Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1, 2 and 4 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The compression quality may vary from 0 to 1 and can be -selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 -ioctl's. For maximum flexibility, both the default active video format and the -default compression quality depend on how the image sensor being used is -initialized (as described in the documentation of the API for the image sensors -supplied by this driver). - - -11. Video frame formats [1] -======================= -The SN9C10x PC Camera Controllers can send images in two possible video -formats over the USB: either native "Sequential RGB Bayer" or Huffman -compressed. The latter is used to achieve high frame rates. The current video -format may be selected or queried from the user application by calling the -VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2 API -specifications. - -The name "Sequential Bayer" indicates the organization of the red, green and -blue pixels in one video frame. Each pixel is associated with a 8-bit long -value and is disposed in memory according to the pattern shown below: - -B[0] G[1] B[2] G[3] ... B[m-2] G[m-1] -G[m] R[m+1] G[m+2] R[m+2] ... G[2m-2] R[2m-1] -... -... B[(n-1)(m-2)] G[(n-1)(m-1)] -... G[n(m-2)] R[n(m-1)] - -The above matrix also represents the sequential or progressive read-out mode of -the (n, m) Bayer color filter array used in many CCD/CMOS image sensors. - -One compressed video frame consists of a bitstream that encodes for every R, G, -or B pixel the difference between the value of the pixel itself and some -reference pixel value. Pixels are organised in the Bayer pattern and the Bayer -sub-pixels are tracked individually and alternatingly. For example, in the -first line values for the B and G1 pixels are alternatingly encoded, while in -the second line values for the G2 and R pixels are alternatingly encoded. - -The pixel reference value is calculated as follows: -- the 4 top left pixels are encoded in raw uncompressed 8-bit format; -- the value in the top two rows is the value of the pixel left of the current - pixel; -- the value in the left column is the value of the pixel above the current - pixel; -- for all other pixels, the reference value is the average of the value of the - pixel on the left and the value of the pixel above the current pixel; -- there is one code in the bitstream that specifies the value of a pixel - directly (in 4-bit resolution); -- pixel values need to be clamped inside the range [0..255] for proper - decoding. - -The algorithm purely describes the conversion from compressed Bayer code used -in the SN9C10x chips to uncompressed Bayer. Additional steps are required to -convert this to a color image (i.e. a color interpolation algorithm). - -The following Huffman codes have been found: -0: +0 (relative to reference pixel value) -100: +4 -101: -4? -1110xxxx: set absolute value to xxxx.0000 -1101: +11 -1111: -11 -11001: +20 -110000: -20 -110001: ??? - these codes are apparently not used - -[1] The Huffman compression algorithm has been reverse-engineered and - documented by Bertrik Sikken. - - -12.

Overview -=========== -This driver supports the video streaming capabilities of the devices mounting -Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681 -based cameras should be supported as well. - -The driver is divided into two modules: the basic one, "w9968cf", is needed for -the supported devices to work; the second one, "w9968cf-vpp", is an optional -module, which provides some useful video post-processing functions like video -decoding, up-scaling and colour conversions. - -Note that the official kernels do neither include nor support the second -module for performance purposes. Therefore, it is always recommended to -download and install the latest and complete release of the driver, -replacing the existing one, if present. - -The latest and full-featured version of the W996[87]CF driver can be found at: -http://www.linux-projects.org. Please refer to the documentation included in -that package, if you are going to use it. - -Up to 32 cameras can be handled at the same time. They can be connected and -disconnected from the host many times without turning off the computer, if -your system supports the hotplug facility. - -To change the default settings for each camera, many parameters can be passed -through command line when the module is loaded into memory. - -The driver relies on the Video4Linux, USB and I2C core modules. It has been -designed to run properly on SMP systems as well. An additional module, -"ovcamchip", is mandatory; it provides support for some OmniVision image -sensors connected to the W996[87]CF chips; if found in the system, the module -will be automatically loaded by default (provided that the kernel has been -compiled with the automatic module loading option). - - -5. Supported devices -==================== -At the moment, known W996[87]CF and OV681 based devices are: -- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor) -- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip) -- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor) -- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor) -- Lebon LDC-035A (unknown image sensor) -- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor) -- OmniVision OV8610-EDE (OmniVision OV8610 sensor) -- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor) -- Pretec Digi Pen-II (OmniVision OV7620 sensor) -- Pretec DigiPen-480 (OmniVision OV8610 sensor) - -If you know any other W996[87]CF or OV681 based cameras, please contact me. - -The list above does not imply that all those devices work with this driver: up -until now only webcams that have an image sensor supported by the "ovcamchip" -module work. Kernel messages will always tell you whether this is case. - -Possible external microcontrollers of those webcams are not supported: this -means that still images cannot be downloaded from the device memory. - -Furthermore, it's worth to note that I was only able to run tests on my -"Creative Labs Video Blaster WebCam Go". Donations of other models, for -additional testing and full support, would be much appreciated. - - -6. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux, USB -and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not -actually using any external "ovcamchip" module, given that the W996[87]CF -driver depends on the version of the module present in the official kernels. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # I2C support - # - CONFIG_I2C=m - -The I2C core module can be compiled statically in the kernel as well. - - # OmniVision Camera Chip support - # - CONFIG_VIDEO_OVCAMCHIP=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, only one of the modules -below is necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_W9968CF=m - - -7. Module loading -================= -To use the driver, it is necessary to load the "w9968cf" module into memory -after every other module required. - -Loading can be done this way, from root: - - [root@localhost home]# modprobe usbcore - [root@localhost home]# modprobe i2c-core - [root@localhost home]# modprobe videodev - [root@localhost home]# modprobe w9968cf - -At this point the pertinent devices should be recognized: "dmesg" can be used -to analyze kernel messages: - - [user@localhost home]$ dmesg - -There are a lot of parameters the module can use to change the default -settings for each device. To list every possible parameter with a brief -explanation about them and which syntax to use, it is recommended to run the -"modinfo" command: - - [root@locahost home]# modinfo w9968cf - - -8.

Optional device control through "sysfs" +========================================== +If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, +it is possible to read and write both the ET61X[12]51 and the image sensor +registers by using the "sysfs" filesystem interface. + +There are four files in the /sys/class/video4linux/videoX directory for each +registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files +control the ET61X[12]51 bridge, while the other two control the sensor chip. +"reg" and "i2c_reg" hold the values of the current register index where the +following reading/writing operations are addressed at through "val" and +"i2c_val". Their use is not intended for end-users, unless you know what you +are doing. Remember that you must be logged in as root before writing to them. + +As an example, suppose we were to want to read the value contained in the +register number 1 of the sensor register table - which is usually the product +identifier - of the camera registered as "/dev/video0": + + [root@localhost #] cd /sys/class/video4linux/video0 + [root@localhost #] echo 1 > i2c_reg + [root@localhost #] cat i2c_val + +Note that if the sensor registers can not be read, "cat" will fail. +To avoid race conditions, all the I/O accesses to the files are serialized. + + +9.

Notes for V4L2 application developers +========================================= +This driver follows the V4L2 API specifications. In particular, it enforces two +rules: + +- exactly one I/O method, either "mmap" or "read", is associated with each +file descriptor. Once it is selected, the application must close and reopen the +device to switch to the other I/O method; + +- although it is not mandatory, previously mapped buffer memory should always +be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. +The same number of buffers as before will be allocated again to match the size +of the new video frames, so you have to map the buffers again before any I/O +attempts on them. + +Consistently with the hardware limits, this driver also supports image +downscaling with arbitrary scaling factors from 1 and 2 in both directions. +However, the V4L2 API specifications don't correctly define how the scaling +factor can be chosen arbitrarily by the "negotiation" of the "source" and +"target" rectangles. To work around this flaw, we have added the convention +that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the +scaling factor is restored to 1. + +This driver supports two different video formats: the first one is the "8-bit +Sequential Bayer" format and can be used to obtain uncompressed video data +from the device through the current I/O method, while the second one provides +"raw" compressed video data (without frame headers not related to the +compressed data).

See http://www.xirlink.com/ +(renamed to http://www.veo.com), http://www.ibmpccamera.com, +or http://www.c-itnow.com/ for details and pictures. + +This very chipset ("X Chip", as marked at the factory) +is used in several other cameras, and they are supported +as well: + +- IBM NetCamera +- Veo Stingray + +The Linux driver was developed with camera with following +model number (or FCC ID): KSX-XVP510. This camera has three +interfaces, each with one endpoint (control, iso, iso). This +type of cameras is referred to as "model 1". These cameras are +no longer manufactured. + +Xirlink now manufactures new cameras which are somewhat different. +In particular, following models [FCC ID] belong to that category: + +XVP300 [KSX-X9903] +XVP600 [KSX-X9902] +XVP610 [KSX-X9902] + +(see http://www.xirlink.com/ibmpccamera/ for updates, they refer +to these new cameras by Windows driver dated 12-27-99, v3005 BETA) +These cameras have two interfaces, one endpoint in each (iso, bulk). +Such type of cameras is referred to as "model 2". They are supported +(with exception of 352x288 native mode). + +Some IBM NetCameras (Model 4) are made to generate only compressed +video streams. This is great for performance, but unfortunately +nobody knows how to decompress the stream :-( Therefore, these +cameras are *unsupported* and if you try to use one of those, all +you get is random colored horizontal streaks, not the image! +If you have one of those cameras, you probably should return it +to the store and get something that is supported. + +Tell me more about all that "model" business +-------------------------------------------- + +I just invented model numbers to uniquely identify flavors of the +hardware/firmware that were sold. It was very confusing to use +brand names or some other internal numbering schemes. So I found +by experimentation that all Xirlink chipsets fall into four big +classes, and I called them "models". Each model is programmed in +its own way, and each model sends back the video in its own way. + +Quirks of Model 2 cameras: +------------------------- + +Model 2 does not have hardware contrast control. Corresponding V4L +control is implemented in software, which is not very nice to your +CPU, but at least it works. + +This driver provides 352x288 mode by switching the camera into +quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting +this mode to 10 frames per second or less, in ideal conditions on +the bus (USB is shared, after all). The frame rate +has to be programmed very conservatively. Additional concern is that +frame rate depends on brightness setting; therefore the picture can +be good at one brightness and broken at another! I did not want to fix +the frame rate at slowest setting, but I had to move it pretty much down +the scale (so that framerate option barely matters). I also noticed that +camera after first powering up produces frames slightly faster than during +consecutive uses. All this means that if you use 352x288 (which is +default), be warned - you may encounter broken picture on first connect; +try to adjust brightness - brighter image is slower, so USB will be able +to send all data. However if you regularly use Model 2 cameras you may +prefer 176x144 which makes perfectly good I420, with no scaling and +lesser demands on USB (300 Kbits per second, or 26 frames per second). + +Another strange effect of 352x288 mode is the fine vertical grid visible +on some colored surfaces. I am sure it is caused by me not understanding +what the camera is trying to say. Blame trade secrets for that. + +The camera that I had also has a hardware quirk: if disconnected, +it needs few minutes to "relax" before it can be plugged in again +(poorly designed USB processor reset circuit?) + +[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't +observed this particular flaw in it.] + +Model 2 camera can be programmed for very high sensitivity (even starlight +may be enough), this makes it convenient for tinkering with. The driver +code has enough comments to help a programmer to tweak the camera +as s/he feels necessary. + +WHAT YOU NEED: + +- A supported IBM PC (C-it) camera (model 1 or 2) + +- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work) + +- A Video4Linux compatible frame grabber program such as xawtv. + +HOW TO COMPILE THE DRIVER: + +You need to compile the driver only if you are a developer +or if you want to make changes to the code. Most distributions +precompile all modules, so you can go directly to the next +section "HOW TO USE THE DRIVER". + +The ibmcam driver uses usbvideo helper library (module), +so if you are studying the ibmcam code you will be led there. + +The driver itself consists of only one file in usb/ directory: +ibmcam.c. This file is included into the Linux kernel build +process if you configure the kernel for CONFIG_USB_IBMCAM. +Run "make xconfig" and in USB section you will find the IBM +camera driver. Select it, save the configuration and recompile. + +HOW TO USE THE DRIVER: + +I recommend to compile driver as a module. This gives you an +easier access to its configuration. The camera has many more +settings than V4L can operate, so some settings are done using +module options. + +To begin with, on most modern Linux distributions the driver +will be automatically loaded whenever you plug the supported +camera in. Therefore, you don't need to do anything. However +if you want to experiment with some module parameters then +you can load and unload the driver manually, with camera +plugged in or unplugged. + +Typically module is installed with command 'modprobe', like this: + +# modprobe ibmcam framerate=1 + +Alternatively you can use 'insmod' in similar fashion: + +# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1 + +Module can be inserted with camera connected or disconnected. + +The driver can have options, though some defaults are provided. + +Driver options: (* indicates that option is model-dependent) + +Name Type Range [default] Example +-------------- -------------- -------------- ------------------ +debug Integer 0-9 [0] debug=1 +flags Integer 0-0xFF [0] flags=0x0d +framerate Integer 0-6 [2] framerate=1 +hue_correction Integer 0-255 [128] hue_correction=115 +init_brightness Integer 0-255 [128] init_brightness=100 +init_contrast Integer 0-255 [192] init_contrast=200 +init_color Integer 0-255 [128] init_color=130 +init_hue Integer 0-255 [128] init_hue=115 +lighting Integer 0-2* [1] lighting=2 +sharpness Integer 0-6* [4] sharpness=3 +size Integer 0-2* [2] size=1 + +Options for Model 2 only: + +Name Type Range [default] Example +-------------- -------------- -------------- ------------------ +init_model2_rg Integer 0..255 [0x70] init_model2_rg=128 +init_model2_rg2 Integer 0..255 [0x2f] init_model2_rg2=50 +init_model2_sat Integer 0..255 [0x34] init_model2_sat=65 +init_model2_yb Integer 0..255 [0xa0] init_model2_yb=200 + +debug You don't need this option unless you are a developer. + If you are a developer then you will see in the code + what values do what. 0=off. + +flags This is a bit mask, and you can combine any number of + bits to produce what you want. Usually you don't want + any of extra features this option provides: + + FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed + VIDIOCSYNC ioctls without failing. + Will work with xawtv, will not + with xrealproducer. Default is + not set. + FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode. + FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have + magic meaning to developers. + FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen, + useful only for debugging. + FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers. + FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as + it was received from the camera. + Default (not set) is to mix the + preceding frame in to compensate + for occasional loss of Isoc data + on high frame rates. + FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame + prior to use; relevant only if + FLAGS_SEPARATE_FRAMES is set. + Default is not to clean frames, + this is a little faster but may + produce flicker if frame rate is + too high and Isoc data gets lost. + FLAGS_NO_DECODING 128 This flag turns the video stream + decoder off, and dumps the raw + Isoc data from the camera into + the reading process. Useful to + developers, but not to users. + +framerate This setting controls frame rate of the camera. This is + an approximate setting (in terms of "worst" ... "best") + because camera changes frame rate depending on amount + of light available. Setting 0 is slowest, 6 is fastest. + Beware - fast settings are very demanding and may not + work well with all video sizes. Be conservative. + +hue_correction This highly optional setting allows to adjust the + hue of the image in a way slightly different from + what usual "hue" control does. Both controls affect + YUV colorspace: regular "hue" control adjusts only + U component, and this "hue_correction" option similarly + adjusts only V component. However usually it is enough + to tweak only U or V to compensate for colored light or + color temperature; this option simply allows more + complicated correction when and if it is necessary. + +init_brightness These settings specify _initial_ values which will be +init_contrast used to set up the camera. If your V4L application has +init_color its own controls to adjust the picture then these +init_hue controls will be used too. These options allow you to + preconfigure the camera when it gets connected, before + any V4L application connects to it. Good for webcams. + +init_model2_rg These initial settings alter color balance of the +init_model2_rg2 camera on hardware level. All four settings may be used +init_model2_sat to tune the camera to specific lighting conditions. These +init_model2_yb settings only apply to Model 2 cameras. + +lighting This option selects one of three hardware-defined + photosensitivity settings of the camera. 0=bright light, + 1=Medium (default), 2=Low light. This setting affects + frame rate: the dimmer the lighting the lower the frame + rate (because longer exposition time is needed). The + Model 2 cameras allow values more than 2 for this option, + thus enabling extremely high sensitivity at cost of frame + rate, color saturation and imaging sensor noise. + +sharpness This option controls smoothing (noise reduction) + made by camera. Setting 0 is most smooth, setting 6 + is most sharp. Be aware that CMOS sensor used in the + camera is pretty noisy, so if you choose 6 you will + be greeted with "snowy" image. Default is 4. Model 2 + cameras do not support this feature. + +size This setting chooses one of several image sizes that are + supported by this driver. Cameras may support more, but + it's difficult to reverse-engineer all formats. + Following video sizes are supported: + + size=0 128x96 (Model 1 only) + size=1 160x120 + size=2 176x144 + size=3 320x240 (Model 2 only) + size=4 352x240 (Model 2 only) + size=5 352x288 + size=6 640x480 (Model 3 only) + + The 352x288 is the native size of the Model 1 sensor + array, so it's the best resolution the camera can + yield. The best resolution of Model 2 is 176x144, and + larger images are produced by stretching the bitmap. + Model 3 has sensor with 640x480 grid, and it works too, + but the frame rate will be exceptionally low (1-2 FPS); + it may be still OK for some applications, like security. + Choose the image size you need. The smaller image can + support faster frame rate. Default is 352x288. + +For more information and the Troubleshooting FAQ visit this URL: + + http://www.linux-usb.org/ibmcam/ + +WHAT NEEDS TO BE DONE: + +- The button on the camera is not used. I don't know how to get to it. + I know now how to read button on Model 2, but what to do with it? + +- Camera reports its status back to the driver; however I don't know + what returned data means. If camera fails at some initialization + stage then something should be done, and I don't do that because + I don't even know that some command failed. This is mostly Model 1 + concern because Model 2 uses different commands which do not return + status (and seem to complete successfully every time). + +- Some flavors of Model 4 NetCameras produce only compressed video + streams, and I don't know how to decode them. + +CREDITS: + +The code is based in no small part on the CPiA driver by Johannes Erdfelt, +Randy Dunlap, and others. Big thanks to them for their pioneering work on that +and the USB stack. + +I also thank John Lightsey for his donation of the Veo Stingray camera. diff --git a/Documentation/video4linux/ov511.txt b/Documentation/video4linux/ov511.txt new file mode 100644 index 0000000..142741e --- /dev/null +++ b/Documentation/video4linux/ov511.txt @@ -0,0 +1,288 @@ +------------------------------------------------------------------------------- +Readme for Linux device driver for the OmniVision OV511 USB to camera bridge IC +------------------------------------------------------------------------------- + +Author: Mark McClelland +Homepage: http://alpha.dyndns.org/ov511 + +INTRODUCTION: + +This is a driver for the OV511, a USB-only chip used in many "webcam" devices. +Any camera using the OV511/OV511+ and the OV6620/OV7610/20/20AE should work. +Video capture devices that use the Philips SAA7111A decoder also work.

If you have a complicated setup involving + both OV511 and OV511+ cameras, trial-and-error may be necessary for + finding the optimum setting. + + NAME: compress + TYPE: integer (Boolean) + DEFAULT: 0 + DESC: Set this to 1 to turn on the camera's compression engine. This can + potentially increase the frame rate at the expense of quality, if you + have a fast CPU. You must load the proper compression module for your + camera before starting your application (ov511_decomp or ov518_decomp). + + NAME: testpat + TYPE: integer (Boolean) + DEFAULT: 0 + DESC: This configures the camera's sensor to transmit a colored test-pattern + instead of an image.

These + normally do not need to be changed. + + NAME: lightfreq + TYPE: integer (0, 50, or 60) + DEFAULT: 0 (use sensor default) + DESC: Sets the sensor to match your lighting frequency. This can reduce the + appearance of "banding", i.e. horizontal lines or waves of light and + dark that are often caused by artificial lighting. Valid values are: + 0 - Use default (depends on sensor, most likely 60 Hz) + 50 - For European and Asian 50 Hz power + 60 - For American 60 Hz power + + NAME: bandingfilter + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Enables the sensor´s banding filter exposure algorithm. This reduces + or stabilizes the "banding" caused by some artificial light sources + (especially fluorescent). You might have to set lightfreq correctly for + this to work right. As an added bonus, this sometimes makes it + possible to capture your monitor´s output. + + NAME: fastset + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Allows picture settings (brightness, contrast, color, and hue) to take + effect immediately, even in the middle of a frame. This reduces the + time to change settings, but can ruin frames during the change. Only + affects OmniVision sensors. + + NAME: force_palette + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Forces the palette (color format) to a specific value. If an + application requests a different palette, it will be rejected, thereby + forcing it to try others until it succeeds. This is useful for forcing + greyscale mode with a color camera, for example. Supported modes are: + 0 (Allows all the following formats) + 1 VIDEO_PALETTE_GREY (Linear greyscale) + 10 VIDEO_PALETTE_YUV420 (YUV 4:2:0 Planar) + 15 VIDEO_PALETTE_YUV420P (YUV 4:2:0 Planar, same as 10) + + NAME: backlight + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Setting this flag changes the exposure algorithm for OmniVision sensors + such that objects in the camera's view (i.e. your head) can be clearly + seen when they are illuminated from behind. It reduces or eliminates + the sensor's auto-exposure function, so it should only be used when + needed.

(automatically assign the next available minor(s)) + DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices. + For example, "unit_video=1,3" will make the driver use /dev/video1 and + /dev/video3 for the first two devices it detects. Additional devices + will be assigned automatically starting at the first available device + node (/dev/video0 in this case). Note that you cannot specify 0 as a + minor number. This feature requires kernel version 2.4.5 or higher. + + NAME: remove_zeros + TYPE: integer (Boolean) + DEFAULT: 0 (do not skip any incoming data) + DESC: Setting this to 1 will remove zero-padding from incoming data. This + will compensate for the blocks of corruption that can appear when the + camera cannot keep up with the speed of the USB bus (eg. at low frame + resolutions). This feature is always enabled when compression is on. + + NAME: mirror + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This + might be necessary if your camera has a custom lens assembly. This has + no effect with video capture devices. + + NAME: ov518_color + TYPE: integer (Boolean) + DEFAULT: 0 (off) + DESC: Enable OV518 color support. This is off by default since it doesn't + work most of the time. If you want to try it, you must also load + ov518_decomp with the "nouv=0" parameter. If you get improper colors or + diagonal lines through the image, restart your video app and try again. + Repeat as necessary. + +WORKING FEATURES: + o Color streaming/capture at most widths and heights that are multiples of 8. + o Monochrome (use force_palette=1 to enable) + o Setting/getting of saturation, contrast, brightness, and hue (only some of + them work the OV7620 and OV7620AE) + o /proc status reporting + o SAA7111A video capture support at 320x240 and 640x480 + o Compression support + o SMP compatibility + +HOW TO CONTACT ME: + +You can email me at mark@alpha.dyndns.org .

Overview and features +======================== +This driver attempts to support the video interface of the devices mounting the +SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers. + +It's worth to note that SONiX has never collaborated with the author during the +development of this project, despite several requests for enough detailed +specifications of the register tables, compression engine and video data format +of the above chips. Nevertheless, these informations are no longer necessary, +becouse all the aspects related to these chips are known and have been +described in detail in this documentation. + +The driver relies on the Video4Linux2 and USB core modules. It has been +designed to run properly on SMP systems as well. + +The latest version of the SN9C10x driver can be found at the following URL: +http://www.linux-projects.org/ + +Some of the features of the driver are: + +- full compliance with the Video4Linux2 API (see also "Notes for V4L2 + application developers" paragraph); +- available mmap or read/poll methods for video streaming through isochronous + data transfers; +- automatic detection of image sensor; +- support for built-in microphone interface; +- support for any window resolutions and optional panning within the maximum + pixel area of image sensor; +- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both + directions (see "Notes for V4L2 application developers" paragraph); +- two different video formats for uncompressed or compressed data in low or + high compression quality (see also "Notes for V4L2 application developers" + and "Video frame formats" paragraphs); +- full support for the capabilities of many of the possible image sensors that + can be connected to the SN9C10x bridges, including, for istance, red, green, + blue and global gain adjustments and exposure (see "Supported devices" + paragraph for details); +- use of default color settings for sunlight conditions; +- dynamic I/O interface for both SN9C10x and image sensor control and + monitoring (see "Optional device control through 'sysfs'" paragraph); +- dynamic driver control thanks to various module parameters (see "Module + parameters" paragraph); +- up to 64 cameras can be handled at the same time; they can be connected and + disconnected from the host many times without turning off the computer, if + the system supports hotplugging; +- no known bugs. + + +5. Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux and +USB. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + +To enable advanced debugging functionality on the device through /sysfs: + + # Multimedia devices + # + CONFIG_VIDEO_ADV_DEBUG=y + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, the modules below are +necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +The SN9C103 controller also provides a built-in microphone interface. It is +supported by the USB Audio driver thanks to the ALSA API: + + # Sound + # + CONFIG_SOUND=y + + # Advanced Linux Sound Architecture + # + CONFIG_SND=m + + # USB devices + # + CONFIG_SND_USB_AUDIO=m + +And finally: + + # USB Multimedia devices + # + CONFIG_USB_SN9C102=m + + +6. Module loading +================= +To use the driver, it is necessary to load the "sn9c102" module into memory +after every other module required: "videodev", "usbcore" and, depending on +the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". + +Loading can be done as shown below: + + [root@localhost home]# modprobe sn9c102 + +At this point the devices should be recognized. You can invoke "dmesg" to +analyze kernel messages and verify that the loading process has gone well: + + [user@localhost home]$ dmesg + + +7. Module parameters +==================== +Module parameters are listed below: +------------------------------------------------------------------------------- +Name: video_nr +Type: short array (min = 0, max = 64) +Syntax: <-1|n[,...]> +Description: Specify V4L2 minor mode number: + -1 = use next available + n = use minor number n + You can specify up to 64 cameras this way. + For example: + video_nr=-1,2,-1 would assign minor number 2 to the second + recognized camera and use auto for the first one and for every + other camera. +Default: -1 +------------------------------------------------------------------------------- +Name: force_munmap +Type: bool array (min = 0, max = 64) +Syntax: <0|1[,...]> +Description: Force the application to unmap previously mapped buffer memory + before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not + all the applications support this feature. This parameter is + specific for each detected camera. + 0 = do not force memory unmapping + 1 = force memory unmapping (save memory) +Default: 0 +------------------------------------------------------------------------------- +Name: frame_timeout +Type: uint array (min = 0, max = 64) +Syntax: +Description: Timeout for a video frame in seconds. This parameter is + specific for each detected camera. This parameter can be + changed at runtime thanks to the /sys filesystem interface. +Default: 2 +------------------------------------------------------------------------------- +Name: debug +Type: ushort +Syntax: +Description: Debugging information level, from 0 to 3: + 0 = none (use carefully) + 1 = critical errors + 2 = significant informations + 3 = more verbose messages + Level 3 is useful for testing only, when only one device + is used. It also shows some more informations about the + hardware being detected. This parameter can be changed at + runtime thanks to the /sys filesystem interface. +Default: 2 +------------------------------------------------------------------------------- + + +8. Optional device control through "sysfs" [1] +========================================== +If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, +it is possible to read and write both the SN9C10x and the image sensor +registers by using the "sysfs" filesystem interface. + +Every time a supported device is recognized, a write-only file named "green" is +created in the /sys/class/video4linux/videoX directory. You can set the green +channel's gain by writing the desired value to it. The value may range from 0 +to 15 for SN9C101 or SN9C102 bridges, from 0 to 127 for SN9C103 bridges. +Similarly, only for SN9C103 controllers, blue and red gain control files are +available in the same directory, for which accepted values may range from 0 to +127. + +There are other four entries in the directory above for each registered camera: +"reg", "val", "i2c_reg" and "i2c_val". The first two files control the +SN9C10x bridge, while the other two control the sensor chip. "reg" and +"i2c_reg" hold the values of the current register index where the following +reading/writing operations are addressed at through "val" and "i2c_val". Their +use is not intended for end-users. Note that "i2c_reg" and "i2c_val" will not +be created if the sensor does not actually support the standard I2C protocol or +its registers are not 8-bit long. Also, remember that you must be logged in as +root before writing to them. + +As an example, suppose we were to want to read the value contained in the +register number 1 of the sensor register table - which is usually the product +identifier - of the camera registered as "/dev/video0": + + [root@localhost #] cd /sys/class/video4linux/video0 + [root@localhost #] echo 1 > i2c_reg + [root@localhost #] cat i2c_val + +Note that "cat" will fail if sensor registers cannot be read. + +Now let's set the green gain's register of the SN9C101 or SN9C102 chips to 2: + + [root@localhost #] echo 0x11 > reg + [root@localhost #] echo 2 > val + +Note that the SN9C10x always returns 0 when some of its registers are read. +To avoid race conditions, all the I/O accesses to the above files are +serialized. + +The sysfs interface also provides the "frame_header" entry, which exports the +frame header of the most recent requested and captured video frame. The header +is always 18-bytes long and is appended to every video frame by the SN9C10x +controllers. As an example, this additional information can be used by the user +application for implementing auto-exposure features via software. + +The following table describes the frame header: + +Byte # Value Description +------ ----- ----------- +0x00 0xFF Frame synchronisation pattern. +0x01 0xFF Frame synchronisation pattern. +0x02 0x00 Frame synchronisation pattern. +0x03 0xC4 Frame synchronisation pattern. +0x04 0xC4 Frame synchronisation pattern. +0x05 0x96 Frame synchronisation pattern. +0x06 0xXX Unknown meaning. The exact value depends on the chip; + possible values are 0x00, 0x01 and 0x20. +0x07 0xXX Variable value, whose bits are ff00uzzc, where ff is a + frame counter, u is unknown, zz is a size indicator + (00 = VGA, 01 = SIF, 10 = QSIF) and c stands for + "compression enabled" (1 = yes, 0 = no). +0x08 0xXX Brightness sum inside Auto-Exposure area (low-byte). +0x09 0xXX Brightness sum inside Auto-Exposure area (high-byte). + For a pure white image, this number will be equal to 500 + times the area of the specified AE area.

For + images that are not pure white, the value scales down + according to relative whiteness. + according to relative whiteness. + +The following bytes are used by the SN9C103 bridge only: + +0x0C 0xXX Unknown meaning +0x0D 0xXX Unknown meaning +0x0E 0xXX Unknown meaning +0x0F 0xXX Unknown meaning +0x10 0xXX Unknown meaning +0x11 0xXX Unknown meaning + +The AE area (sx, sy, ex, ey) in the active window can be set by programming the +registers 0x1c, 0x1d, 0x1e and 0x1f of the SN9C10x controllers, where one unit +corresponds to 32 pixels. + +[1] Part of the meaning of the frame header has been documented by Bertrik + Sikken. + + +9. Supported devices +==================== +None of the names of the companies as well as their products will be mentioned +here. They have never collaborated with the author, so no advertising. + +From the point of view of a driver, what unambiguously identify a device are +its vendor and product USB identifiers.

Non-available hardware will not be supported by the author of this +driver. + + +10. Notes for V4L2 application developers +========================================= +This driver follows the V4L2 API specifications. In particular, it enforces two +rules: + +- exactly one I/O method, either "mmap" or "read", is associated with each +file descriptor. Once it is selected, the application must close and reopen the +device to switch to the other I/O method; + +- although it is not mandatory, previously mapped buffer memory should always +be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. +The same number of buffers as before will be allocated again to match the size +of the new video frames, so you have to map the buffers again before any I/O +attempts on them. + +Consistently with the hardware limits, this driver also supports image +downscaling with arbitrary scaling factors from 1, 2 and 4 in both directions. +However, the V4L2 API specifications don't correctly define how the scaling +factor can be chosen arbitrarily by the "negotiation" of the "source" and +"target" rectangles. To work around this flaw, we have added the convention +that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the +scaling factor is restored to 1. + +This driver supports two different video formats: the first one is the "8-bit +Sequential Bayer" format and can be used to obtain uncompressed video data +from the device through the current I/O method, while the second one provides +"raw" compressed video data (without frame headers not related to the +compressed data). The compression quality may vary from 0 to 1 and can be +selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 +ioctl's. For maximum flexibility, both the default active video format and the +default compression quality depend on how the image sensor being used is +initialized (as described in the documentation of the API for the image sensors +supplied by this driver). + + +11. Video frame formats [1] +======================= +The SN9C10x PC Camera Controllers can send images in two possible video +formats over the USB: either native "Sequential RGB Bayer" or Huffman +compressed. The latter is used to achieve high frame rates. The current video +format may be selected or queried from the user application by calling the +VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2 API +specifications. + +The name "Sequential Bayer" indicates the organization of the red, green and +blue pixels in one video frame. Each pixel is associated with a 8-bit long +value and is disposed in memory according to the pattern shown below: + +B[0] G[1] B[2] G[3] ... B[m-2] G[m-1] +G[m] R[m+1] G[m+2] R[m+2] ... G[2m-2] R[2m-1] +... +... B[(n-1)(m-2)] G[(n-1)(m-1)] +... G[n(m-2)] R[n(m-1)] + +The above matrix also represents the sequential or progressive read-out mode of +the (n, m) Bayer color filter array used in many CCD/CMOS image sensors. + +One compressed video frame consists of a bitstream that encodes for every R, G, +or B pixel the difference between the value of the pixel itself and some +reference pixel value. Pixels are organised in the Bayer pattern and the Bayer +sub-pixels are tracked individually and alternatingly. For example, in the +first line values for the B and G1 pixels are alternatingly encoded, while in +the second line values for the G2 and R pixels are alternatingly encoded. + +The pixel reference value is calculated as follows: +- the 4 top left pixels are encoded in raw uncompressed 8-bit format; +- the value in the top two rows is the value of the pixel left of the current + pixel; +- the value in the left column is the value of the pixel above the current + pixel; +- for all other pixels, the reference value is the average of the value of the + pixel on the left and the value of the pixel above the current pixel; +- there is one code in the bitstream that specifies the value of a pixel + directly (in 4-bit resolution); +- pixel values need to be clamped inside the range [0..255] for proper + decoding. + +The algorithm purely describes the conversion from compressed Bayer code used +in the SN9C10x chips to uncompressed Bayer. Additional steps are required to +convert this to a color image (i.e. a color interpolation algorithm). + +The following Huffman codes have been found: +0: +0 (relative to reference pixel value) +100: +4 +101: -4? +1110xxxx: set absolute value to xxxx.0000 +1101: +11 +1111: -11 +11001: +20 +110000: -20 +110001: ??? - these codes are apparently not used + +[1] The Huffman compression algorithm has been reverse-engineered and + documented by Bertrik Sikken. + + +12.

Overview +=========== +This driver supports the video streaming capabilities of the devices mounting +Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681 +based cameras should be supported as well. + +The driver is divided into two modules: the basic one, "w9968cf", is needed for +the supported devices to work; the second one, "w9968cf-vpp", is an optional +module, which provides some useful video post-processing functions like video +decoding, up-scaling and colour conversions. + +Note that the official kernels do neither include nor support the second +module for performance purposes. Therefore, it is always recommended to +download and install the latest and complete release of the driver, +replacing the existing one, if present. + +The latest and full-featured version of the W996[87]CF driver can be found at: +http://www.linux-projects.org. Please refer to the documentation included in +that package, if you are going to use it. + +Up to 32 cameras can be handled at the same time. They can be connected and +disconnected from the host many times without turning off the computer, if +your system supports the hotplug facility. + +To change the default settings for each camera, many parameters can be passed +through command line when the module is loaded into memory. + +The driver relies on the Video4Linux, USB and I2C core modules. It has been +designed to run properly on SMP systems as well. An additional module, +"ovcamchip", is mandatory; it provides support for some OmniVision image +sensors connected to the W996[87]CF chips; if found in the system, the module +will be automatically loaded by default (provided that the kernel has been +compiled with the automatic module loading option). + + +5. Supported devices +==================== +At the moment, known W996[87]CF and OV681 based devices are: +- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor) +- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip) +- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor) +- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor) +- Lebon LDC-035A (unknown image sensor) +- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor) +- OmniVision OV8610-EDE (OmniVision OV8610 sensor) +- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor) +- Pretec Digi Pen-II (OmniVision OV7620 sensor) +- Pretec DigiPen-480 (OmniVision OV8610 sensor) + +If you know any other W996[87]CF or OV681 based cameras, please contact me. + +The list above does not imply that all those devices work with this driver: up +until now only webcams that have an image sensor supported by the "ovcamchip" +module work. Kernel messages will always tell you whether this is case. + +Possible external microcontrollers of those webcams are not supported: this +means that still images cannot be downloaded from the device memory. + +Furthermore, it's worth to note that I was only able to run tests on my +"Creative Labs Video Blaster WebCam Go". Donations of other models, for +additional testing and full support, would be much appreciated. + + +6. Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux, USB +and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not +actually using any external "ovcamchip" module, given that the W996[87]CF +driver depends on the version of the module present in the official kernels. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + + # I2C support + # + CONFIG_I2C=m + +The I2C core module can be compiled statically in the kernel as well. + + # OmniVision Camera Chip support + # + CONFIG_VIDEO_OVCAMCHIP=m + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, only one of the modules +below is necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +And finally: + + # USB Multimedia devices + # + CONFIG_USB_W9968CF=m + + +7. Module loading +================= +To use the driver, it is necessary to load the "w9968cf" module into memory +after every other module required. + +Loading can be done this way, from root: + + [root@localhost home]# modprobe usbcore + [root@localhost home]# modprobe i2c-core + [root@localhost home]# modprobe videodev + [root@localhost home]# modprobe w9968cf + +At this point the pertinent devices should be recognized: "dmesg" can be used +to analyze kernel messages: + + [user@localhost home]$ dmesg + +There are a lot of parameters the module can use to change the default +settings for each device.

Overview and features +======================== +This driver supports the video interface of the devices mounting the ZC0301 +Image Processor and Control Chip. + +The driver relies on the Video4Linux2 and USB core modules. It has been +designed to run properly on SMP systems as well. + +The latest version of the ZC0301 driver can be found at the following URL: +http://www.linux-projects.org/ + +Some of the features of the driver are: + +- full compliance with the Video4Linux2 API (see also "Notes for V4L2 + application developers" paragraph); +- available mmap or read/poll methods for video streaming through isochronous + data transfers; +- automatic detection of image sensor; +- video format is standard JPEG; +- dynamic driver control thanks to various module parameters (see "Module + parameters" paragraph); +- up to 64 cameras can be handled at the same time; they can be connected and + disconnected from the host many times without turning off the computer, if + the system supports hotplugging; + + +5. Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux and +USB. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, the modules below are +necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +The ZC0301 controller also provides a built-in microphone interface. It is +supported by the USB Audio driver thanks to the ALSA API: + + # Sound + # + CONFIG_SOUND=y + + # Advanced Linux Sound Architecture + # + CONFIG_SND=m + + # USB devices + # + CONFIG_SND_USB_AUDIO=m + +And finally: + + # USB Multimedia devices + # + CONFIG_USB_ZC0301=m + + +6. Module loading +================= +To use the driver, it is necessary to load the "zc0301" module into memory +after every other module required: "videodev", "usbcore" and, depending on +the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". + +Loading can be done as shown below: + + [root@localhost home]# modprobe zc0301 + +At this point the devices should be recognized. You can invoke "dmesg" to +analyze kernel messages and verify that the loading process has gone well: + + [user@localhost home]$ dmesg + + +7. Module parameters +==================== +Module parameters are listed below: +------------------------------------------------------------------------------- +Name: video_nr +Type: short array (min = 0, max = 64) +Syntax: <-1|n[,...]> +Description: Specify V4L2 minor mode number: + -1 = use next available + n = use minor number n + You can specify up to 64 cameras this way. + For example: + video_nr=-1,2,-1 would assign minor number 2 to the second + registered camera and use auto for the first one and for every + other camera. +Default: -1 +------------------------------------------------------------------------------- +Name: force_munmap +Type: bool array (min = 0, max = 64) +Syntax: <0|1[,...]> +Description: Force the application to unmap previously mapped buffer memory + before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not + all the applications support this feature. This parameter is + specific for each detected camera. + 0 = do not force memory unmapping + 1 = force memory unmapping (save memory) +Default: 0 +------------------------------------------------------------------------------- +Name: frame_timeout +Type: uint array (min = 0, max = 64) +Syntax: +Description: Timeout for a video frame in seconds. This parameter is + specific for each detected camera. This parameter can be + changed at runtime thanks to the /sys filesystem interface. +Default: 2 +------------------------------------------------------------------------------- +Name: debug +Type: ushort +Syntax: +Description: Debugging information level, from 0 to 3: + 0 = none (use carefully) + 1 = critical errors + 2 = significant informations + 3 = more verbose messages + Level 3 is useful for testing only, when only one device + is used at the same time. It also shows some more informations + about the hardware being detected. This module parameter can be + changed at runtime thanks to the /sys filesystem interface. +Default: 2 +------------------------------------------------------------------------------- + + +8. Supported devices +==================== +None of the names of the companies as well as their products will be mentioned +here. They have never collaborated with the author, so no advertising. + +From the point of view of a driver, what unambiguously identify a device are +its vendor and product USB identifiers. Below is a list of known identifiers of +devices mounting the ZC0301 Image Processor and Control Chips: + +Vendor ID Product ID +--------- ---------- +0x041e 0x4017 +0x041e 0x401c +0x041e 0x401e +0x041e 0x4034 +0x041e 0x4035 +0x046d 0x08ae +0x0ac8 0x0301 +0x10fd 0x8050 + +The list above does not imply that all those devices work with this driver: up +until now only the ones that mount the following image sensors are supported; +kernel messages will always tell you whether this is the case: + +Model Manufacturer +----- ------------ +PAS202BCB PixArt Imaging, Inc. + + +9. Notes for V4L2 application developers +======================================== +This driver follows the V4L2 API specifications. In particular, it enforces two +rules: + +- exactly one I/O method, either "mmap" or "read", is associated with each +file descriptor. Once it is selected, the application must close and reopen the +device to switch to the other I/O method; + +- although it is not mandatory, previously mapped buffer memory should always +be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. +The same number of buffers as before will be allocated again to match the size +of the new video frames, so you have to map the buffers again before any I/O +attempts on them. + + +10. Contact information +======================= +The author may be contacted by e-mail at . + +GPG/PGP encrypted e-mail's are accepted. The GPG key ID of the author is +'FCE635A4'; the public 1024-bit key should be available at any keyserver; +the fingerprint is: '88E8 F32F 7244 68BA 3958 5D40 99DA 5D2A FCE6 35A4'. + + +11.

Each open after the first would allocate a new dvr buffer (1880 KB) and leak the old buffer. The first close would de-allocate the dvr buffer and cause all other open dvrs to stop working. This patch allows only a single O_RDONLY open of the drv device, as per the API specification. Multiple O_WRONLY opens are still allowed and don't appear to cause any problems.

This breaks the tda1004x at least, and causes it to fail to tune until the budget-av module is reloaded. This patch adds an exported function to dvb_frontend that allows a card to forcibly reinitialise a frontend. The budget-av now does this on CAM reset, which corrects this problem. since they do not tie the CAM reset line to the frontend reset line.

msp3400c did not detect the second carrier, thus being always mono. - properly mute the msp3400c while detecting the carrier. - fix checks on the presence of scart2/3 inputs and scart 2 output. - implement proper audio mode fallbacks for msp3400c/d, identical to the way msp3400g works. - MODE_STEREO no longer produces dual languages when set for a bilingual transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear both languages of a bilingual transmission. This is much more intuitive for the user and is in accordance with the preferred usage in the v4l2 specification. - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices, completely mangling the audmode/rxsubchans handling. v4l2 calls now do v4l2 calls to the i2c devices. - fixed broken i2c_vidiocschan in bttv. - add start/end lines to LOG_STATUS.
