Description Sven Gothel 2013-09-09 16:15:55 CEST
The GLMediaPlayer implementation shall utilize a lock-free ringbuffer
and perform decoding on a separate 'stream-worker' thread.

This shall allow to utilize GLMediaPlayer in a non blocking fashion,
as well as using multiple non-blocking instances within one-scene.
Comment 1 Sven Gothel 2013-09-09 16:36:36 CEST
Some cherry picked changes from the git commits:

- AudioSink (ALAudioSink) works multithreaded
  - Added: play/pause/flush

- AudioSink.AudioFormat refined

- GLMediaPlayer.State refined

- GLMediaPlayer. events refined, incl. error states

- StreamWorker added (see API doc)
  - Proper error propagation

- Non blocking getNextTexture()

- Use non blocking LFRingbuffer (new in GlueGen)

- Use passive non-blocking video synchronization

- Use URI instead of URL

- Add volume control


- Fix audio- and video-only playback

- Reduce 'frame-drop' to 'every 2nd only' pattern

- Split initGLStream(..) -> initStream(..) + initGL(GL)

  - glFinish() in native code where it's required
