* stagefright: Squashed commit of pause/resume featuresSteve Kondik2015-11-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add 2 APIs (suspend/resume) in MediaPlayer - API:suspend() will just pause the player and release all the decoders to replace release() which will release the whole player - API:resume() will just init the decoders again, then start() will be called to restart streaming playback - Add a check in AwesomePlayer::onVideoEvent() to make sure the first seek operation will always seek to the next i-frame Change-Id: Ie4c82906a2a056378119921a656128ebdc1007c4 audio: Add pause support for hardware omx component - ADSP doesn't enter sleep state after wma playback is paused and power suspended. - No support for NT session pause in case of hardware component. NT session need to be paused to put ADSP into power collapse. - Add support of pause in stagefright to ensure device enters suspend mode. Also add intermediate states to avoid concurrency issues between read and pause. Change-Id: I41b946b8c8805e6ee303646b63513b5b16514ef6 libstagefright: Drain input buffer on resume - Buffers returned from codec in paused state are not drained. When codec is resumed these buffers are not drained until the next flush, and may cause timed out issue. - Added change to drain input buffers for sw decoders when resuming. Change-Id: Ida2ab1d5dc3a1910accdd6fb89548262a912d8e7 CRs-Fixed: 569585, 574967 libstagefright: camcorder pause-resume implementation - Add pause resume feature in camcorder app. So that user can pause recording and resume later which results in a single recorded clip. Change-Id: Id19c45ae5bb85265aa4d5304b160ebf119d9575a libstagefright: support pause/resume for timelapse recording Modify the timestamp calculation mechanism in CameraSourceTimeLapse in order to support pause/resume.

| | | | | | | | | | Camera HAL v1 uses vendor-specific camera-source meta-data mode, but software encoders use generic gralloc-source mode, so they are not compatible. Change-Id: I0d1bab8eada26dcb70c97b1eec83f06d1f331239 Signed-off-by: Lajos Molnar <lajos@google.com> Bug: 11446505

* Add framework support for camcorder zoom.Wu-cheng Li2011-06-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to allow applications using the camera during recording. Camera service allows only one client at a time. Since camcorder application needs to own the camera to do things like zoom, the media recorder cannot access the camera directly during recording. So ICameraRecordingProxy is a proxy of ICamera, which allows the media recorder to start/stop the recording and release recording frames. ICameraRecordingProxyListener is an interface that allows the recorder to receive video frames during recording. ICameraRecordingProxy startRecording() stopRecording() releaseRecordingFrame() ICameraRecordingProxyListener dataCallbackTimestamp() The camcorder app opens the camera and starts the preview. The app passes ICamera and ICameraRecordingProxy to the media recorder by MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in MediaRecorder::start(). After setup, the recorder disconnects from camera service. The recorder calls ICameraRecordingProxy::startRecording() and passes a ICameraRecordingProxyListener to the app. The app connects back to camera service and starts the recording. The app owns the camera and can do things like zoom. The media recorder receives the video frames from the listener and releases them by ICameraRecordingProxy::releaseRecordingFrame. The recorder calls ICameraRecordingProxy::stopRecording() to stop the recording. The call sequences are as follows: 1. The app: Camera.unlock(). 2. The app: MediaRecorder.setCamera(). 3. Start recording (1) The app: MediaRecorder.start(). (2) The recorder: ICamera.unlock() and ICamera.disconnect(). (3) The recorder: ICameraRecordingProxy.startRecording(). (4) The app: ICamera.reconnect(). (5) The app: ICamera.startRecording(). 4. During recording (1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp() (2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame(). 5. Stop recording (1) The app: MediaRecorder.stop() (2) The recorder: ICameraRecordingProxy.stopRecording(). (3) The app: ICamera.stopRecording(). bug:2644213 Change-Id: I15269397defc25cbbcae16abc071c8349c123122

* Implemented frequent read returns for quick stop in time lapse.Nipun Kwatra2010-09-171-1/+60
| | | | | | | | | | | | | | | | | | | If the frame capture interval is large, read will block for a long time. Due to the way the mediaRecorder framework works, a stop() call from mediaRecorder waits until the read returns, causing a long wait for stop() to return. To avoid this, we return a copy of the last read frame with the same time stamp if a frame is not available quickly. This keeps the read() call from blocking too long. This method is triggered when startQuickReadReturns() is called on CameraSourceTimeLapse. In the still camera case, also using waitRelative on Condition instaed of sleeping, so that we can wake it up. Also for the idle check instead of sleeping, we now wait on a condition variable, which is woken up when the last takePicture callback gets called.

* Moving decision to use still camera to CameraSourceTimeLapseNipun Kwatra2010-09-031-3/+6
| | | | | | | | | | | | CameraSourceTimeLapse now decides whether to use still or video camera automatically. It checks if the passed in size is a valid preview size and if it is, then uses the video camera else uses the still camera. Removed from StagefrightRecorder the support to set parameter useStillCameraForTimeLapse. Change-Id: I71f5b0fc7080ca524792381efe918d22e41a7f36
* Implementing getSupportedPictureSizesNipun Kwatra2010-08-021-3/+5
| | | | | | | Go through all the supported picture sizes and choose the smallest one with both dimensions higher than the passed in video width and height. Change-Id: I4e9fe7a6384a0feeb9e069239ec68c70fb5f3033
* Support for video size to be different from captured picture size.Nipun Kwatra2010-07-291-0/+33
| | | | | | | | | Adding support to allow video size to be different than the supported picture sizes. A picture size larger than the demanded video size is chosen. Captured pictures are then cropped to the size of the desired video size. Cropping is done from the the center portion of the picture. Change-Id: I6bcbe16f94b6ecbcf28b7f46826a81b4b6b8cbc3
* Allowing setting of time lapse parameters through MediaRecorder.javaNipun Kwatra2010-07-221-0/+3
| | | | | | | | added setTimeLapseParameters() to MediaRecorder.java and SetParameter support in StagefrightRecorder to allow enabling time lapse and setting the corresponding parameters. Change-Id: I509040aa71f8d3fc37337b0894a81d9c0fd7a40a
* Restart preview after each takePicture is done.Nipun Kwatra2010-07-201-1/+14
| | | | | | | | | Preview is called when CAMERA_MSG_COMPRESSED_IMAGE is recieved by dataCallback(). It needs to be started as a new thread so that the callback can return, and the camera can know that takePicture() is done. Change-Id: I4d0febbc993aac43b37f9f4a824e9c7b8785f19e
* Adding support for timelapse capture using still camera's takepicture.Nipun Kwatra2010-07-191-0/+129
Also moving entire implementation into a new class CameraSourceTimeLapse which inherits from CameraSource. For timelapse capture using still camera, we start a thread which runs a loop in which it calls Camera::takePicture() and then sleeps until the next frame should be captured. The function dataCallback() handles the callback from the camera with the raw image data. This function copies the data and creates an artificial timestamp corresponding to one frame time ahead of the last encoded frame's time stamp. It then calls dataCallbackTimestamp() of the base class which will think that it recieved the frame from a video camera and proceed as usual. For moving the implementation to the subclass CameraSourceTimeLapse, added a few virtual functions to CameraSource, which do the current thing for the base class, but specialized things for CameraSourceTimeLapse. E.g. startCameraRecording() in the base class just calls mCamera->startRecording(), while in CameraSourceTimeLapse it may start a thread for the still camera case.
