How we can perform live encoding of videos to mp4 and stream it in ASP.NET

I'm using flow player for streaming videos to my browser.The videos are uploaded by the users and they may upload different formats. What will be solution to stream the videos as mp4 , what ever be the format they upload. I'm currently using ffmpeg commands.

The problem is after encoding the video is getting down scaled.Also if the user upload large video file the encoding itself takes more time.

I need to stream the videos as soon as its uploaded t开发者_开发知识库o the server, what ever may be the format(like in youtube).

I'd look into ffmpeg as it allows yo to transcode just about every video format on the planet.

However; I'm not sure of it's real-time capabilities or it's abilities to stream it's output. Might be a good place to start though.

I think you could do this by automating expression encoder on the server even though it is mainly used for smooth streaming format but expression encoder isn't opensource or free :(
