C# - Upload Stream And Play Video?

I have to make an interface to upload large videos up to 30MB then stream and convert it into FLV format and then play it in a browser... this is required on my site in the "Video Gallery" module. My web application is in C# and ASP.NET. I can also use jQuery.

I have to send the video file in chunks then merge it at the server, stream it, create thumbnail for the video and then play it.

I found some code but it is all in PHP. I haven't found any C#, ASP.NET code.

Finally I got the code to upload the video file in chunks... like create its thumbnail and display the video in a browser.

Here is code to upload the video in chunks.

Upload button click

protected void btnUploadVideo_Click(object sender, EventArgs e)
{
UploadVideoFile obj = new UploadVideoFile();
string FileName = fuUploadVideo.FileName;
string DestPath = Server.MapPath("Videos");
