Okay. I've got a few ogg files I've created using a desktop recording tool. I've transcoded them using ffmpeg once (mainly to clip out the beginnings and the ends).

Now, I have 3 such files which I want to concatenate into a single .ogv file. I tried using oggCat, it crashed with some kind of error (I tried concatenating a file to itself using oggCat and that failed too leading me to believe that my distro is shipping a broken version of the package). Simply cating the files works but I can't seek which is not cool. mencoder run like this mencoder -ovc lavc -oac lavc file1.ogv file2.ogv file3.ogv -o complete.ogv. It transcodes the files into an avi and clips off a little of the 3 videos.

So, how do I do this?

Update 1: My current workaround is to transcode the 3 files into .mpg using ffmpeg, then cating them together and then transcoding them back into ogv.

Update 2: PiTiVi works for this kind of thing but I need something from the command line that I can automate and script.
