      opensles: Work around race condition in Android < 4.2 that leads to deadlocks on shutdown · c842df1c
      Sebastian Dröge authored
      We need to sleep a bit before destroying the player object
      because of a bug in Android in versions < 4.2.
      OpenSLES is using AudioTrack for rendering the sound. AudioTrack
      has a thread that pulls raw audio from the buffer queue and then
      passes it forward to AudioFlinger (AudioTrack::processAudioBuffer()).
      This thread is calling various callbacks on events, e.g. when
      an underrun happens or to request data. OpenSLES sets this callback
      on AudioTrack (audioTrack_callBack_pullFromBuffQueue() from
      android_AudioPlayer.cpp). Among other things this is taking a lock
      on the player interface.
      Now if we destroy the player interface object, it will first of all
      take the player interface lock (IObject_Destroy()). Then it destroys
      the audio player instance (android_audioPlayer_destroy()) which then
      calls stop() on the AudioTrack and deletes it. Now the destructor of
      AudioTrack will wait until the rendering thread (AudioTrack::processAudioBuffer())
      has finished.
      If all this happens with bad timing it can happen that the rendering
      thread is currently e.g. handling underrun but did not lock the player
      interface object yet. Then destroying happens and takes the lock and waits
      for the thread to finish. Then the thread tries to take the lock and waits
      We wait a bit before destroying the player object to make sure that
      the rendering thread finished whatever it was doing, and then stops
      (note: we called gst_opensles_ringbuffer_stop() before this already).
