[MPlayer-users] cat files

[Philippe De Neve]

Hi All,

I tried concatenating files by:

cat berlitz_junior_raw.avi volver_raw.avi | mencoder -noidx   -oac  
copy -ovc  copy -o out.avi -

this results in only the first file being copied to ou.avi. The  
second file volver_raw.avi is not added. Strange.
Has anybody an idea what could be going wrong?
Below some output of mencoder and analyze with ffmpeg of both source  
files.

tnx for all help, wfr, phil.
