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.

After inslalling enable this plugin from edit->preferences->plugins(tab).

HindiTransliteration (c# and JavaScript implementation, works offline)

When I was in college, I wrote a quick and dirty code to transliterate in Hindi (DevNagari Script). Much before Google's Implementation.
{This code was kept on my old desktop PC,I Thought, its a good idea to share with the rest of the world}

Though my implementation is not very robust, but Its very simple and small. It does not require any Internet connection and can work offline.

Note: code was originally written in C#.net and converted to javascript latter.
Here is C#.net Code(solution zipped)

You need to call function

DoTransLitrate(str)

Where str(as input): Phonetically typed (in English) Hindi .
Returns: Hindi in Devnagari script.


Using JavaScript Code
Get the JavaScript File from here include in your html page and call function

DoTransLitrate()
