I have two files: old.avi, and old.mkv.
I want to take the video stream from old.avi (XVID) and an audio stream from old.mk (aac) and create a new AVI file.
Since I have to do it repatedly I want to use ffmpg, and I have been trying to understand the parameters, and this is the one I understand it should work:
ffmpeg -i old.avi -vcodec copy -i old.mkv -acodec libmp3lame new.avi
ffmpeg -i old.avi -c:v copy -i old.mkv -c:a libmp3lame new.avi
But I get Unknown decoder 'copy':
c:\ffmpeg>ffmpeg -i old.avi -vcodec copy -i old.mkv -acodec libmp3lame new.avi

Any ideas on what I'm doing wrong?
