Buid Exoplayer with ffmpeg extension
22 février 2021, par Bhoomi KalavadiyaI'm making IP streaming android application. In which I'm using exoplayer 2.12.0. Input video is having mpeg-L2 audio layer codec which is not supported by exoplayer https://github.com/google/ExoPlayer/issues/6525. So i'm using ffmpeg extension to render audio.

I have followed https://github.com/google/ExoPlayer/tree/release-v2/extensions/ffmpeg steps to build ffmpeg extension with android-ndk-r21d-linux-x86_64 and FFmpeg-release-4.3.

Added code in the application

TrackSelector trackSelectors = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory()); RenderersFactory renderersFactory=new DefaultRenderersFactory(this,EXTENSION_RENDERER_MODE_ON,DEFAULT_ALLOWED_VIDEO_JOINING_TIME_MS); player = ExoPlayerFactory.newSimpleInstance(this, renderersFactory,trackSelectors);


Still audio is not coming and the log is as below

Here, With or without ffmpeg extension, I'm not getting audioEnabled log in Eventlogger.
Also after using ffmpeg audio render, I'm not getting it is being used or not.
Or am I missing some configuration of ffmpeg extension to Exoplayer ?

FFmpeg HLS streaming - Why the program date time of older segment changing when re-streaming after discontinuity
9 novembre 2020, par Suriya KrishFollowing is the ffmpeg command to stream the data.

#EXT-X-ENDLIST


When the re-stream happens(in case of restarting the streaming service), the program date time of older segments(before #EXT-X-DISCONTINUITY) also get changed like below, which is unexpected.

Why the program date time of older segment should change ? Should we add any arguments in ffmpeg command to handle this ?
