we need to mix one video stream with 31 audio tracks, so you can switch in vlc to different languages.
we have video stream in webm and 31 audio streams as vorbis (ogg) and want to bring them all together in one webm-container.
Video file: video.webm
Audio file: language_1.ogg; language_2.ogg; .....;
should be muxed in:
video.webm (with 31 language Audio-tracks)
What is the ffmpeg-Script? Thank you very much for help.
