[FFmpeg-user] merging or joining videos

[Venkatasubramaniam R]

Hi,

Once I had used MP4Box package in Linux for concatenating smaller mp4 files
to get a big one. It worked pretty well, but I had not tried it on AVI
files.

May be you could try MP4Box (which comes as a command line tool when
installing gpac package : http://gpac.wp.institut-telecom.fr/mp4box/).

All the best,
-Venkat.
