I have started working on this bug, a in progress git branch is available: https://github.com/xranby/jogl/commits/FFMPEGMediaPlayer-audio I have now implemented a crude proof of concept FFMPEGMediaPlayer with plain Java Sound and a most simple a/v sync. I only buffer audio frames for now. Video is played a bit ahead of time in order to generate enough audio frame buffer to prevent audio buffer under-runs during video "Thread.sleep" sync. https://github.com/xranby/jogl/commit/062f3e9e1ecfeb63ea61eb540d94d17a2de1412a .. commits are to numerous to list here, however, Xerxes's brought in audio frame decoding w/ JOAL output support! Latest FFMPEG GLMediaPlayer / ALAudioSink refined such support ranging from: [from 6332e13b2f0aa9818d37802302f04c90a4fa4239 to 1693604b4daae4571069b58bdc863516b95999a6] |
Created attachment 457 [details] decode.c ffmpeg/libav audio decode and openal playback native example. Adding audio playback support to FFMPEGMediaPlayer will make it awesome. The attached decode.c demonstrate audio decode using ffmpeg/libav and playback using openal. We may choose to let the JOGL util FFMPEGMediaPlayer package depend on JOAL in order to facilitate easy playback of decoded audio frames.
