Join wmv files?

[jhaquo]

hi
id like to merge some WMV files, any ideas how please?


i tried with cat, it makes a big file of the size of all the small wmv's togheter, but when i play it it stops after the first file lenght

i hope you can help

The first part of a WMV file is the header with file length and encoding info, you can't just cat them together. WMV files are a proprietary format, if the files were MP3, OGG, AIFF, AU or WAV format there are a couple of programs that you can use to edit these files.

well there are plenty of windows apps that will get the work done, but ic ant use them using wine because of some missing files(which i installed but it still give me the same errors)

You may use mencoder (from mplayer, in the multiverse repository), but the results seem to be a bit buggy sometimes.
If you want to give it a try, enter the following to a command line:

mencoder -oac copy -ovc copy -o NEWVIDEOFILE part1.wmv part2.wmv part2.wmv ...

or just
mencoder -oac copy -ovc copy -o NEWVIDEOFILE part*

If all video files are named in correct alphanumerical order.
Mencoder creates an AVI file, which is mostly playable for xine, vlc and mplayer, but sometimes I get an error from KPlayer (which bases on mplayer - strange, hm?) that my system is too slow, and the merged video is played really slow

Did you had some success with windows video software and wine jet?

I have the same question, and I would like to use GUI.

This command line method worked great for me.

avidemux (2.3) supports wmv input but not output...you could join them with avidemux and export/convert them to a different format...

the mencoder method above works, but as was mentioned, the results are buggy. specifically, a/v sync is not perfect (video is playing back slightly faster than it is supposed to, and thus audio seems to "lag").
