In ffmpeg-speak, those are separate streams. The word "channel" is used for components of one stream, such as stereo or 5.1. Yes, sure it can be done. But an MP3 file can only hold one stream, so you need to use a different container format, such as your suggested MP4. Just map multiple audio inputs to ffmpeg, it will place the corresponding outputs into the resulting container: $ ffmpeg -i video -i audio1 -i audio2 -map 0 -map 1 -map 2 output.mp4 (Don't forget to add your relevant options. ;-)) You can even tell the output what those languages are, by using the proper metadata: [...] -metadata:s:a:0 language=eng -metadata:s:a:1 language=deu Moritz _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
