Yes.
But this only applies to "simply concatenating" them - as in:

"cat file1.mpg file2.mpg > output.mpg"

versus:

"cat file1.avi file2.avi > output.avi"

I know that output.avi will not make any sense, whereas output.mpg is valid.


But, as I assume that ffmpeg is able to remux containers, I also  
assumed it would be possible to do remux (and possibly transcode)  
several input files with matching audio/video codec into a new file.

I've successfully been doing this with several thousands of files  
(FFv1/PCM in AVI) with mencoder - so it's technically possible.
