Actually not, the whole information thrown by the command was sent but the
ffmpeg version and other related stuff which hadn't to do with file
information. I supress in order to give a clean output.

Actually I don't which is better. I am clearly new in this subject. Since
Mencoder is widely used I didn't thinks it could be a problem.
In fact it concatenates well unless files with different codec/fps.

If you meant about Mencoder it seems it is not, however the error message
specifies a different codec not frame rate.

No, I didn't. I'll tray it later then. Thank for your suggestion.
