* GLMediaPlayer Multithreaded Decoding: GLMediaPlayer* (Part-3) - WIPSven Gothel2013-08-142-79/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - GLMediaPlayer - Remove State.Stopped and method stop() - redundant, use pause() / destroy() - Add notion of stream IDs - Add API doc: State / Stream-ID incl. html-anchor - Expose video/audio PTS, .. - Expose optional AudioSink - Min multithreaded textureCount is 4 (EGL* and FFMPEG*) - GLMediaPlayerImpl - Move AudioSink rel. impl. to this class, allowing a tight video implementation reusing logic. - Remove 'synchronized' methods, synchronize on State where applicable - implement new methods (see above) - playSpeed is handled partially in AudioSink. If it exeeds AudioSink's capabilities, drop audio and rely solely on video sync. - video sync (WIP) - video pts delay based on geometric weight - reset video SCR if 'out of range', resync w/ PTS - - FramePusher - allow interruption when pausing/stopping, while waiting for next avail free frame to decode. - FFMPEGMediaPlayer - Add proper AudioDataFormat negotiation AudioSink <-> libav - Parse libav's SampleFormat - Remove AudioSink interaction (moved to GLMediaPlayerImpl) - Tests (MovieSimple, MovieCube): - Add aid/vid selection - Add KeyListener for actions: seek(..), play()/pause(), setPlaySpeed(..) - Dump perf-string each 2s - TODO: - Add audio sync in AudioSink, similar to GLMediaPlayer's weighted video delay, here: drop audio frames.
* GLMediaPlayer: Add multithreaded decoding w/ textureCount > 2 where ↵Sven Gothel2013-08-102-14/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | available EGL/FFMPeg. WIP! Off-thread decoding: If validated (impl) textureCount > 2, decoding happens on extra thread. If decoding requires GL context, a shared context is created for decoding thread. API Changes: - initGLStream(..): Adds 'textureCount' as argument. - TextureSequence.TexSeqEventListener.newFrameAvailable(..) exposes the new frame available - TextureSequence.TextureFrame exposes the PTS (video) Implementation: - 'int validateTextureCount(int)': implementation decides whether textureCount can be > 2, i.e. off-thread decoding allowed, default is NO w/ textureCount==2! - 'boolean requiresOffthreadGLCtx()': implementation decides whether shared context is required for off-thread decoding - 'syncFrame2Audio(TextureFrame frame)': implementation shall handle a/v sync, due to audio stream details (pts, buffered frames) - FFMPEGMediaPlayer extends GLMediaPlayerImpl, no more EGLMediaPlayerImpl (redundant) +++ - SyncedRingbuffer: Expose T[] array +++ TODO: - syncAV! - test Android
* FFMPEGPlayer Audio Sink Refactoring ..Sven Gothel2013-07-192-57/+34
| | | | | | | | | | | | | | | | - AudioSink w/ AudioFrame and formats public - ALAudioSink uses a circular buffer now, hence relaxes the one-threaded player mode - FFMPEGMediaPlayer uses multiple audio frames (equal to the ALAudioSink number) and wraps data to NIO buffer w/o copy. - FFMPEGMediaPlayer audio threading currently disabled: distorted sound Seems that the ALAudioSink's circular buffer usage is good enough for now. - Verbosity only w/ DEBUG flag - New SyncedRingbuffer for effcient synced buffering

* FFMPEGMediaPlayer: Fix NPE; Add remarks about binary incompatibility in ↵Sven Gothel2012-04-211-155/+198
| | | | | | | | | | | upcoming version (master branch) We need native structure access methods to deal with API changes in the libav headers, which break binary compatibility! Currently we are binary compatible w/ [0.6 ?, ] 0.7 and 0.8 but not w/ trunk. Tested: Linux, Windows and OSX (self compiled binary)
* Adding initial Libav/FFMpeg GLMediaPlayer implementationSven Gothel2012-04-162-0/+780
The Java classes already slipped through in commit 10935e1ec0d8ed677bc3fddfaa8cd73898a3bcbf - oops. Since we cannot provide a Libav binary (even though Google does in Android and Chrome) due to legal uncertainities .. we dynamically link to an existing Libav / FFmpeg library in a 'relaxed' manner. Ie. we allow certain recent functions to be absent to be able to run on a wider range of Libav versions. Currently tested on Debian Linux and Windows7 64bit/32bit Binaries for Win/OSX: - Windows http://ffmpeg.zeranoe.com/builds/ - OSX http://www.ffmpegx.com/ Features: - Dynamic relaxed linking to Libav (see above) - YUV420P texture lookup function shader stub (conversion to RGB) - 1-copy only (decoder buffer to texture) - simple - uses libavformat's network streaming - fixes some odd PTS values TODO: - Audio output (Should use OpenAL, duh) - Seek works poorly - Offthread multi-texture fetching for smoother animation - Maybe more pixelformat conversions
