Merging videos using command line

[Shady3D]

hi all, there was a tutorial in Linux Journal about extracting mp3 from a video, so i was thinking is there a way to merge 2 videos without using avidmux or other editing program.

Like... video a ends and video b begins?

[Shady3D]

no, i don't want to queue them i want both be the same file

[insineratehymn]

Right... like avi1 + avi2 = comlpeteAvi

[Shady3D]

yes

[insineratehymn]

yes

mencoder -oac copy -ovc copy file1.avi file2.avi -o full_movie.avi

Try that out. Mencoder is in the console and it comes with mplayer, so you should already have it. Replace file1 and file2 with appropriate file names and you will get full_movie.avi (you can change the name of that as well).

Don't be surprised if this takes a long time depending on the size of the original files.

or install transcodesudo apt-get install transcodethis will give you avimerge. then it's as easy as avimerge -i movie*.avi -o mergedmovie.aviwhere movie* is going to be part1.avi, part2.avi, etc..

That will work nicely as well. =)

Exiting...



so do u know whats the problem (thats for the first code)

for the second i am downloading the program now

[insineratehymn]

Post the output of this:
file <name of your movie/s>

Replace <name of your movie/s> with one of the two files you have, do this for each.

vid1.flv: Macromedia Flash Video

[insineratehymn]

Ahh, ok. That explains it. I thought you were messing with avis.
mencoder -oac copy -ovc copy -o c:\video.flv c:\a.flv c:\b.flv

Try that?

[Shady3D]

i didn't quite understand the last code but anyway, i managed to get over that problem by converting to avi then merged them and both scripts worked fine, and thx for ur help

[insineratehymn]

You're welcome.
