Any recommendations on how to convert/transcode OGV to MKV format?
Thanks for that, my apologies though I didn't mean ogg to mkv, I meant ogg to M4V
My fault sorry,
Have you tried HandBrake?
If your on a Windows platform I`d try MediaCoder, one of the best free transcoders I`ve used.
I did try Handbrake but it just came up with a message 'no valid source found'
These were desktop video captures taken on Ubuntu 9.04 using gtk-recordMyDesktop
Handbrake certainly seems to recognise it:
[15:18:19] scan: 10 previews, 1680x1040, 15.000 fps, autocrop = 0/0/0/0, aspect 1.62:1, PAR 1:1
[15:18:19] Title is likely interlaced or telecined (10 out of 10 previews). You should do something about that.
[15:18:19] scan: ignoring title 1, no audio tracks found
[15:18:19] libhb: scan thread found 0 valid title(s)

But then I get this message repeated a few hundred times...

This ogg file plays perfectly in VLC.
While handbrake might recognise the container, it does not recognise the theora codec as the bottom 2 log lines tell you.
Well if it plays fine in VLC, then why not use VLC to transcode it?
A 2 second yahoo search revealed this:-
YouTube - Transcoding from OGG into MP4 using VLC Media Player
I`m sure if you look you`ll find more.
you might want to try the developer snapshot of HB (assuming you are using 0.9.3). It uses a newer version of ffmpeg for decoding among other things, so it might work on you're file.
