How to convert video file in to php?

really i don't see why you just don't exchange it to silverlight or flash, since if you can do that then you can just apply a javascript and put it on there...

You can use ffmpg to convert online to convert video to any format thats the best library i have ever used

i think you need ffmpeg plugin installed and then use the associated functions
