* Use a status_t return type for GL functorsRomain Guy2012-03-261-0/+17
| | | | | | | | | WebView needs more fine-grained control over the behavior of the framework upon execution of the display lists. The new status_t allows WebView to requests its functor to be re-executed directly without causing a redraw of the entire hierarchy. Change-Id: I97a8141dc5c6eeb6805b6024cc1e76fce07d24cc
* Whitespace and indentationGlenn Kasten2012-03-131-5/+5
| | | | | | | | | | | | | | Fix indentation to be multiple of 4. Make it easier to search: sp< not sp < to "switch (...)" instead of "switch(...)" (also "if" and "while") Remove redundant blank line at start or EOF. Remove whitespace at end of line. Remove extra blank lines where they don't add value. Use git diff -b or -w to verify.

* Track volume cleanupGlenn Kasten2012-01-171-4/+7
| | | | | | | | | | | | | | | | | | | | Always read and write track volumes atomically. In most places this was already being done, but there were a couple places where the left and right channels were read independently. Changed constant MAX_GAIN_INT to be a uint32_t instead of a float. It is always used as a uint32_t in comparisons and assignments. Use MAX_GAIN_INT in more places. Now that volume is always accessed atomically, removed the union and alias for uint16_t volume[2], and kept only volumeLR. Removed volatile as it's meaningless. In AudioFlinger, clamp the track volumes read from shared memory before applying master and stream volume. Change-Id: If65e2b27e5bc3db5bf75540479843041b58433f0

* Use channel mask instead of channel count for track creationJean-Michel Trivi2011-06-011-1/+2
| | | | | | | | | | | | | | | | | Record and playback objects (resp AudioRecord and AudioTrack) are created using a channel mask, but this information is lost in the mixer because only the channel count is known to AudioFlinger. A channel count can always be derived from a channel mask. The change consists in: - disambiguiting variable names for channel masks and counts - passing the mask information from the client to AudioFlinger and the mixer. - when using the DIRECT ouput, only verifying the format of the track is compatible with the output's for PCM.

* New fix for issue 4111672: control block flagsEric Laurent2011-04-051-4/+4
| | | | | | | | | | | | | | | The first fix (commit 913af0b4) is problematic because it makes threads in mediaserver process block on the cblk mutex. This is not permitted as it can cause audio to skip or worse have a malicious application prevent all audio playback by keeping the mutex locked. The fix consists in using atomic operations when modifying the control block flags. Also fixed audio_track_cblk_t::framesReady() so that it doesn't block when called from AudioFlinger (only applies when a loop is active). Change-Id: Ibf0abb562ced3e9f64118afdd5036854bb959428

* Fix issue 3439872: video chat and bluetooth SCOEric Laurent2011-03-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes the stability problems experienced when using a bluetooth headset supporting both A2DP and SCO. Problems occur when starting the video chat at which time the A2DP output is being stopped to start SCO. At that time, active AudioTracks are invalidated by AudioFlinger so that a new AudioTrack binder interface can be recreated by the client process on the new mixer thread with correct parameters. The problem was that the process to restore the binder interface was not protected against concurrent requests which caused 2 binder interfaces to be created sometimes. This could lead to permanent client deadlock if one of the client threads was waiting for a condition of the first created binder interface while the second one was created (as the AudioFlinger would only signal conditions on the last one created). This concurrent request situation is more likely to happen when a client uses the JAVA AudioTrack as the JNI implementation uses simultaneously the native AudioTrack callback and write push mechanisms. By doing so, the code that checks if the binder interface should be restored (in obtainBuffer()) is much more likely to be called concurrently from two different threads. The fix consists in protecting the critical binder interface restore phase with a flag in the AudioTrack control block. The first thread acting upon the binder interface restore request will raise the flag and the second thread will just wait for a condition to be signaled when the restore process is complete. Also protected all accesses to the AudioTrack control block by a mutex to prevent access while the track is being destroyed and restored. If a mutex cannot be held (e.g because we call a callback function), acquire a strong reference on the IAudioTrack to prevent its destruction while the cblk is being accessed. Modified AudioTrack JNI to use GetByteArrayElements() instead of GetPrimitiveArrayCritical() when writing audio buffers. Entering a critical section would cause the JNI to abort if a mediaserver crash occurs during a write due to the AudioSystem callback being called during the critical section when media server process restarts. Anyway with current JNI implementation, either versions do not copy data most of the times and the criticial version does not guaranty no data copy. The same modifications have been made to AudioRecord. Change-Id: Idc5aa711a04c3eee180cdd03f44fe17f3c4dcb52

* fix [2835280] Add support for cancelling buffers to ANativeWindowMathias Agopian2010-10-041-4/+6
| | | | | | | | | | There is a new ANativeWindow::cancelBuffer() API that can be used to cancel any dequeued buffer, BEFORE it's been enqueued. The buffer is returned to the list of availlable buffers. dequeue and cancel are not mutually thread safe, they must be called from the same thread or external synchronization must be used.

* Issue 3032913: improve AudioTrack recovery timeEric Laurent2010-09-301-2/+5
| | | | | | | | | | | | This issue showed that when an AudioTrack underruns during a too long period of time and is therefore disabled by audioflinger mixer, it takes an additional delay of up to 3 seconds to recover. This fix adds a simple mechanism to recover immediately when the client application is ready to write data again in the AudioTrack buffer Also throttle warnings on record overflows Change-Id: I8b2c71578dd134b9e60a15ee4d91b70f3799cb3d

* fix [2873058] Surface::dequeueBuffer blocks on last buffer, i.e. cannot ↵Mathias Agopian2010-07-271-8/+0
| | | | | | | | | | | | | | | | | | | | | dequeue all allocated buffers at once. this situation happened when the last buffer needed to be resized (or allocated, the first time). the assumption was that the buffer was in use by SF itself as the current buffer (obviously, this assumption made no sense when the buffer had never been allocated, btw). the system would wait until some other buffer became the "front" buffer. we fix this problem by entirely removing the requirement that the buffer being resized cannot be the front buffer. instead, we just allocate a new buffer and replace the front buffer by the new one. the downside is that this uses more memory (an extra buffer) for a brief amount of time while the old buffer is being reallocated and before it has actually been replaced.

* Native input dispatch rewrite work in progress.Jeff Brown2010-06-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old dispatch mechanism has been left in place and continues to be used by default for now. To enable native input dispatch, edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy. Includes part of the new input event NDK API. Some details TBD. To wire up input dispatch, as the ViewRoot adds a window to the window session it receives an InputChannel object as an output argument. The InputChannel encapsulates the file descriptors for a shared memory region and two pipe end-points. The ViewRoot then provides the InputChannel to the InputQueue. Behind the scenes, InputQueue simply attaches handlers to the native PollLoop object that underlies the MessageQueue. This way MessageQueue doesn't need to know anything about input dispatch per-se, it just exposes (in native code) a PollLoop that other components can use to monitor file descriptor state changes. There can be zero or more targets for any given input event. Each input target is specified by its input channel and some parameters including flags, an X/Y coordinate offset, and the dispatch timeout. An input target can request either synchronous dispatch (for foreground apps) or asynchronous dispatch (fire-and-forget for wallpapers and "outside" targets). Currently, finding the appropriate input targets for an event requires a call back into the WindowManagerServer from native code. In the future this will be refactored to avoid most of these callbacks except as required to handle pending focus transitions. End-to-end event dispatch mostly works! To do: event injection, rate limiting, ANRs, testing, optimization, etc. Change-Id: I8c36b2b9e0a2d27392040ecda0f51b636456de25

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modifications. First drop of audio framework modifications for audio effects support. - AudioTrack/AudioRecord: Added support for auxiliary effects in AudioTrack Added support for audio sessions Fixed left right channel inversion in setVolume() - IAudioFlinger: Added interface methods for effect enumeraiton and instantiation Added support for audio sessions. - IAudioTrack: Added method to attach auxiliary effect. - AudioFlinger Created new classes to control effect engines in effect library and manage effect connections to tracks or output mix: EffectModule: wrapper object controlling the effect engine implementation in the effect library. There is one EffectModule per instance of an effect in a given audio session EffectChain: group of effects associated to one audio session. There is one EffectChain per audio session. EffectChain for session 0 is for output mix effects, other chains are attached to audio tracks with same session ID. Each chain contains a variable number of EffectModules EffectHandle: implements the IEffect interface. There is one EffectHandle object for each application controlling (or using) an effect module. THe EffectModule maintians a list of EffectHandles. Added support for effect modules and effect chains creation in PlaybackThread. modified mixer thread loop to allow track volume control by effect modules and call effect processing. -AudioMixer Each track now specifies its output buffer used by mixer for accumulation Modified mixer process functions to process tracks by groups of tracks with same buffer Modified track process functions to support accumulation to auxiliary channel Change-Id: I26d5f7c9e070a89bdd383e1a659f8b7ca150379c
