Combine FLV/MP4 Videos Together

By Menelaos Bakopoulos • Linux, Video • 0

Hey, a quick post about a script I wrote for combining together multiple video files.
It’s based on a post from: http://www.webupd8.org/2009/05/join-and-split-files-including-video-in.html

Steps during execution

1) The script converts all mp4 and flv files to MPG files.

2) This is done in order to use the CAT command with > to send all the bytes from all files into one location output.mpg.

3) Finally we convert output.mpg  to MP4 and have the final file.

NOTE: I will check into using possible shortcuts to speed up the process.
