* libmedia: Initialize mState/mActive value to avoid possible crashZhou Song2016-04-131-3/+3
| | | | | | | | | | | If track creation fails on server side, mState/mActive is left unitialized. After this a crash can happen when track stop() is called because of a reference to a NULL object. Initialize mState/mActive to specific value in initialized list of track constructor. Change-Id: If8c3611e3229c0c1b14b81285e07b9357fec7658 CRs-Fixed: 992608

* libmedia: correct latency computing of AudioRecordMingming Yin2015-12-191-1/+5
| | | | | | | | | | - Originally, audio record latency is calculated by frame buffers allocated for this track, while the actual latency is determined by audio hal. - Compute the track latency by frame count returned from audio hal when in TRANSFER_CALLBACK mode Change-Id: I26e5e47e8cc3720895b962f7aab8a595a54b7c83

| * Implement audio device callbackEric Laurent2015-05-061-1/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add class AudioSystem::AudioDeviceCallback notifying AudioSystem clients upon device selection change on a given input or output thread. Maintain a list of installed callback per I/O handle in AudioSystem and call registered callbacks when an OPEN of CONFIG_CHANGED event is received on IAudioFlingerClient::ioConfigChanged(). Add methods to AudioTrack and AudioRecord to add and remove device change callbacks. Add methods to AudioTrack and AudioRecord to query currently selected device. ioConfigChanged() events now convey the audio patch describing the input or output thread routing. Fix AudioRecord failure to start when invalidation is handled by start(). Change-Id: I9e938adf025fa712337c63b1e02a8c18f2a20d39

* Move AudioRecord frame count calculations to serverGlenn Kasten2014-07-171-44/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Buffer frame count and notification frame count are now calculated by server instead of by client. The server has more information and can do a better job. Also fix a few bugs: - If a fast track was re-created, even with same pipe depth, it would fail. Now it can correctly re-create a fast track provided the pipe depth is same. - Notification frame count for fast tracks was calculated by client as 1/2 of the total frame count, which is a large value due to the pipe. Now the notification frame count is set by server to the HAL frame count. This should reduce latency for fast tracks. - EVENT_OVERRUN were happening frequently when there was sample rate conversion, because the client didn't know about the sample rate conversion, and under-estimated the necessary buffer size. Now since server calculates the buffer sizes, EVENT_OVERRUN is unlikely. - RecordThread::createRecordTrack_l was checking for mono and stereo for fast tracks. This is not necessary, and now we can handle a multi-channel fast track. Bug: 7498763 Change-Id: I0c581618e8db33084d5ff9ed50a592990c9749e8

| | | | | | | | | | | | | After releasing a reference to a shared memory interface, IPCThreadState::self()->flushCommands() must be called to ensure that the corresponding reference is also cleared immediately in the remote process. Otherwise the binder implementaiton will not push the clear systematically causing the memory region not to be freed. See issues 10711502 and 2801375. Bug: 14057166.
