[FFmpeg-user] Extracting multiple audio stream into one file

[Moritz Barsnick]

Hi,

> I am trying to extract multiple audio stream into one file but I am getting only the first track. Is that even possible?

Yes, it is so. ffmpeg defaults to processing only the first of each type of input stream. You must either specify the ones you desire explicitly, or use "-map 0" to process all streams from input 0. (Plus "-vn" to ignore video, in your case).

Cheers,
