i am converting a bunch of avi videos to mkv, using simply ffmpeg -i "foo.avi" "foo.mkv". Now i have the problem, that in my output-mkv-file exists one video stream (fine) but only the first audio stream from my original file. I figured to map every stream manually with -map 0:1etc, but there has to be a way to tell ffmpeg to keep all streams in the original order? Thank you.

From FFmpeg doc
For example, to map ALL streams from the first input file to output

ffmpeg -i INPUT -map 0 output

Is this a fairly new feature ? When I try it on Ubuntu 11.10, I get the following message: "Number of stream maps must match number of output streams" – gabkdlly Jan 27 '12 at 13:42
