How to fix *.OGV file to upload on YouTube (for Ubuntu 10.04 LTS users)

Hi Guys,
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.

1. Using mencoder.
2. Using ffmpeg.
3. 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)

1. DeVeDe was converting correctly, but messing up with the length of video.
2. ffmpeg completely failed to convert (was gabbling the video like Youtube).

To install mencoder use ubuntu software center.
