[SOLVED] Is it possible to concatenate *.flv flash video files?

lugoteehalt · 10-12-2010, 11:18 AM

Have got a film broken up into 10 minute chunks a la youtube. Tried cat file1.flv file2.flv > file1&2.flv but mplayer stopped, saying 'end of file', half way through playing file1&2.flv.

Is there some way to join them together into one, so the film may be played all the way through.

Just occurred to me you could use an * for the counting numeral in the filename e.g. mplayer file*.flv for file1.flv, file2.flv, etc.. Any road I'll ask the question anyway.

Thanks any help.

Here's a good link with a lot of discussion and command-line examples:

Just a page of reading, and you'll learn a few things along the way.

Better, possibly more authoritative, is the following FAQ entry:

The example listed shows you how to concatenate .flv files using ffmpeg.

Hope this helps!

Indeed helpful.

Code:

ffmpeg -i input1.flv -sameq output1.mpg

where -i means input file and -sameq means same quality. Converts the flv to mpg and mpg files may simply be concatenated as in original post.

The drawback is that it more than doubles the size of the files.
