How to convert all the video format to .flv?

Hi,

I has been assigned to do a project which is similar to Youtube.com
The major technical problem i m facing now is "how to convert the video format to flv when user try to upload any types of video format" (if not all, at least those popular format like .avi, .mpeg, .mov, .wmv...)

I am plan to use PHP, then second choice will be ASP/.NET...

I m doing reserch on http://www.wimpyplayer.com
Any others idea?

Thanks

you would need to pass the file to a converter (the only one I know of is ffmpeg (http://ffmpeg.mplayerhq.hu/) though I do not know if it does .flv) which with PHP would be via the exec() function... this requires that ffmpeg (or whatever converter(s) you use) be installed on the server.

Here is a sdk can help you, You can download the sdk (http://www.*******************/flv_encoder_sdk/), and have a test.
