* Fix issue 2323920: Notification & A2DP audio stutter.Eric Laurent2009-12-222-25/+85
| | | | | | | Modified AudioFlinger duplicating output thread so that audio tracks are not mixed until both outputs (A2DP and hardware) have exited standby mode. This avoids to have one output far ahead of the other and audio frames dropped because the compensation mechanism cannot keep up. Also calculate the maximum wait time in OutputTrack::write() based the on smallest frame count of all output threads instead of the frame count of the thread the OutputTrack is connected to. This avoids starving the thread with the smallest frame count by waiting too long on the other thread. Since the frame count was reduced on hardware output to reduce latency the difference between A2DP and hardware outputs frame counts had become problematic. Also increased the number of overflow buffers to cope with bigger timing differences among outputs.
* fix [2269582] [TOP-10][Passion_1506][APT:Camera]Sometimes camera preview ↵Mathias Agopian2009-12-111-0/+1
| | | | | | | | | | | | | screen is truncated after launching and back to home screen by home key repeatedly When a surface is removed from the screen while it holds a "freeze lock", the release of that lock happens in the destructor as a "safety net". However, it doesn't trigger an update at that point. Make sure that "freeze locks" are released from the transaction at the point a surface is removed from the screen (if it's not on screen, it shouldn't prevent the screen to redraw, and therefore cannot hold a freeze lock). The refresh corresponding to that transaction will pick it up as soon as possible.

* fix [2315900] Monochrome camera preview screen after launching cameraMathias Agopian2009-12-092-50/+69
| | | | | | | | | | this was introduced by a recent change. when we try to figure out the size of the yuv->rgb temporary buffer, the output resolution has not been computed yet and an invalid buffer size is used. most of the time the allocation fails and the system reverts to "standard" GL will uses onle the Y plane. the allocation of the temporary buffer is moved to onDraw(), the first time it is called, by that time, the window is positioned properly.

* Fix issue 2306779: Runtime restart - Init failed at ↵Eric Laurent2009-12-071-12/+4
| | | | | | | | | | android.media.ToneGenerator. The ToneGenerator failed to initialize because no more tracks were available in AudioFlinger mixer. All tracks were used because the duplicating output was failing to free the tracks on audio hardware output mixer when exiting due to a misplaced test on output activity: output tracks where only freed if the duplicating output was active when exiting. The fix consists in freeing the output tracks when the duplicating thread is destroyed without condition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | persistent "error 8" state on future attempts and breaks voice search. Fixed AudioFlinger::openInput() broken in change ddb78e7753be03937ad57ce7c3c842c52bdad65e so that an invalid IO handle (0) is returned in case of failure. Applied the same correction to openOutput(). Modified RecordThread start procedure so that a failure occuring during the first read from audio input stream is detected and causes the record start to fail. Modified RecordThread stop procedure to make sure that audio input stream fd is closed before we exit the stop function. Fixed AudioRecord JAVA and JNI implementation to take status of native AudioRecord::start() into account and not change mRecordingState to RECORDSTATE_RECORDING if start fails.

| * Fix issue 2292062: Audio freezes for three seconds when choosing ringtones ↵Eric Laurent2009-12-011-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with a headset connected and music playing. The problem comes from a deadlock with AudioPolicyService mutex: When the second ringtone starts, this mutex is locked by AudioPolicyService::startOutput() which in turn calls setParameters() to change the output device. Audioflinger::ThreadBase::setParameters() signals the parameter change to the AudioFlinger mixer thread and waits for a condition indicating that the parameter change has been processed. At the same time, the mixer thread detects that the audio track corresponding to the first ring tone has been killed and calls its destructor. This calls AudioPolicyService::releaseOutput() which tries to lock the AudioPolicyService mutex. If this happens before the mixer thread can process the setParameters() command we are deadlocked. The deadlock ends because setParameters() uses a timeout when waiting for the condition. This regression was introduced by change 33736 fixing issue 2265163. The fix consists in calling AudioPolicyService::releaseOutput() from Track::destroy() instead of from Track destructor: as detroy() is never called from the mixer thread loop (as opposed to the destructor) the deadlock described above cannot occur.
* | fix [2297155] SurfaceFlinger's freeze-timeout doesn't workMathias Agopian2009-12-012-13/+22
|/ | | | | | | | | There was bug in the logic that calculated the relative timeout, the start time was reset each time an event was received, which caused the timeout to never occur if an application was constantly redrawing. Now we always check for a timeout when we come back from the waitEvent() and process the "anti-freeze" if needed, regardless of whether an event was received.

| * Issue 2265163: Audio still reported routed through earpiece on sholesEric Laurent2009-11-192-97/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a second attempt to fix the audio routed to earpiece syndrom. The root cause identified this time is the crash of an application having an active AudioTrack playing on the VOICE_CALL stream type. When this happens, the AudioTrack destructor is not called and the audio policy manager is not notified of the track stop. Results a situation where the VOICE_CALL stream is considered as always in use by audio policy manager which makes that audio is routed to earpiece. The fix consists in moving the track start/stop/close notification to audio policiy manager from AudioTrack to AudioFlinger Track objet. The net result is that in the case of a client application crash, the AudioFlinger TrackHandle object (which implements the remote side of the IAudioTrack binder interface) destructor is called which in turn destroys the Track object and we can notify the audio policy manager of the track stop and removal. The same modification is made for AudioRecord although no bug related to record has been reported yet. Also fixed a potential problem if record stop is called while the record thread is exiting.

| | | | | | | | | | | | | | | | | | higher on passion than sholes This change goes with a kernel driver change that reduces the audio buffer size from 4800 bytes (~27ms) to 3072 bytes (~17ms). - The AudioFlinger modifcations in change 0bca68cfff161abbc992fec82dc7c88079dd1a36 have been removed: the short sleep period was counter productive when the AudioTrack is using the call back thread as it causes to many preemptions. - AudioFlinger mixer thread now detects long standby exit time and in this case anticipates start by writing 0s as soon as a track is enabled even if not ready for mixing. - AudioTrack::start() is modified to start call back thread before starting the IAudioTrack so that thread startup time is masked by IAudioTrack start and mixer thread wakeup time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on the EGLImage solution. We simply use copybit to convert from the YUV frame into an EGLImage created for that purpose and proceed with the regular EGLImage code. We need to do this because "regular" GL doesn't support YUV textures. We could improve upon this by detecting exacly what the GL supports and bypass this extra step if not required, but we'll do this later if needed.
