Updating the version is not that easy because I am working in a large render farm environment - but I will bring up this topic to the admins.

I tried your suggestion but I am getting an error: "Data stream encoding not supported yet (only streamcopy)"

Quoting Moritz Barsnick <[email protected]>:

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,
Moritz
