I don't think this is something that AIR has out the box, there're a few workaraounds though, if you find a c or c++ library that does this conversion you can convert it to AS3 using Alchemy, or if you find a separate standalone file conversion app you could use it within AIR using Merapi, or just send it to your server and let the transcoding happens there.
Thanks a lot for the reply
I have not yet tried Alchemey, Is it available to download?
Secondly, I want to do all the conversion locally, So MERAPI might be a good choice, Let me try it
Thanks once again
Hi there yes Alchemy is available to download from labs.adobe.com
