I found out how to concatenate the parts of a video to a single file with MPlayer. It’s relatively easy, so this is just a mini-post to save it for posterity:
$ cat video_part1.avi video_part2.avi ... > temp.avi
$ mencoder -forceidx -oac copy -ovc copy \
temp.avi -o final.avi && \
rm temp.avi

Nice!
I would recommend using “avimerge” from the “transcode” port for doing this.

and more info about it can be found at:

Nice tips :)
Why not just
mencoder -oac copy -ovc copy -noodml -o “joined.avi” “1.avi” “2.avi” ?
(noodml is only for the case the resulting video is larger than 1GB)
Isn’t it simpler to do
mencoder -ovc copy -oac copy -o final.avi video_part1.avi video_part2.avi?Yes, that may work too. I don’t know if this mode of copying also works work -forceidx though, but it’s worth trying it out.
Nice tip for quickly concatenating all your footage!! However, since there is almost always a need for some minor modifications (mainly cutting those unneeded scenes from the beginning and the end of each video part) without re-rendering the video, I highly recommend using a graphical tool for this. Avidemux is an excellent choice for basic video editing.
