Just sharing my experience with *.ogv, while I was trying to upload a video on YouTube.
I was using Ubuntu 10.04 LTS and used gtk-recordMyDesktop to record a screencast and uploaded the video on YouTube, I found that youtube is showing completely gabbled video.
I could not figure out the problem but i simply converted the video to avi and uploaded on youtube, problem solved!!
How to convert to avi?
Basically you have 3 options.
- Using mencoder.
- Using ffmpeg.
- Using DeVeDE.
The only option which worked really nice with me is mencoder (use following command)
mencoder input.ogv -ovc xvid -oac mp3lame -xvidencopts pass=1 -o output.avi
Problem with other 2 options ( i observed)
- DeVeDe was converting correctly, but messing up with the length of video.
- ffmpeg completely failed to convert (was gabbling the video like Youtube).
To install mencoder use ubuntu software center.
