GLMediaPlayer Multithreaded Decoding: GLMediaPlayer* (Part-4) - WIP
- Use Platform.currentTimeMillis() for accurate timing!
- GLMediaPlayer / GLMediaPlayerImpl
- Add DEBUG_NATIVE property jogl.debug.GLMediaPlayer.Native
for verbose impl. messages, i.e. ffmpeg/libav
- Add 'synchronization' section in GLMediaPlayer API doc (WIP)
- Use passive non-blocking video synchronization,
i.e. repeat frames instead of 'sleep'.
Thx to Xerxes's suggestion.
- Add flushing of cached decoded frames,
allowing to remove complicated 'videoSCR_reset_latch'
- FramePusher (threaded decoding):
- Always create a shared context!
- Release context while pausing
- Pre/post 'getNextTextureImpl()' actions only
at makeCurrent/release.
- newFrameAvailable(..) signal after decoded frame is enqueued
- FFMPEGDynamicLibraryBundleInfo
- Bind add. functions of libavcodec:
+ "av_init_packet",
+ "av_new_packet",
+ "av_destruct_packet",
- Bind add. functions of libavformat:
+ "avformat_seek_file",
+ "av_read_play",
+ "av_read_pause",
- DEBUG property := FFMPEGMediaPlayer.DEBUG || DynamicLibraryBundleInfo.DEBUG;
- FFMPEGMediaPlayer
- Use libavformat's 'av_read_play()' and 'av_read_pause()',
which may get utilized for network streams, e.g. RTSP
- getNextTextureImpl(..):
- Fix retry loop
- Use postNextTextureImpl/preNextTextureImpl if desired (PSM)
- Native:
- Use fixed my_av_q2i32(..) macro (again)
- Use INVALID_PTS marker (synced w/ Java code)
- DEBUG: Dump more detailed frame information
- TODO: Consider passing frame_delay, especially for repeated frames!
- Tests (MovieSimple, MovieCube):
- Refine KeyEvents control for seek and speed.
- TODO:
- Proper audio clock calculation - difficult w/ OpenAL !
- Video / Audio sync:
- seek !
- streams w/ very async A/V frames
- Test Streams:
- Five-minute-sync-test.mp4
- Audio-Video-Sync-Test-Calibration-23.98fps-24fps.mp4
- sound_in_sync_test.mp4
- big_buck_bunny_1080p_surround.avi
