Read and send a mp4 file from in C#

Question

I am using the following code to read a mp4 file from the server and send it over http. My server side is a mvc4 controller. Funny thing is the video renders fine in Chrome. But not getting anything on ios devices so I am thinking this could be a response stream header problem. Anything I am missing?

  var stream = new FileStream(path, FileMode.Open, FileAccess.Read); var result = new HttpResponseMessage(HttpStatusCode.OK) { Content = new StreamContent(stream) }; result.Content.Headers.ContentType = new MediaTypeHeaderValue("video/mp4"); result.Content.Headers.ContentRange = new ContentRangeHeaderValue(0, stream.Length); result.Content.Headers.Add("filename", fileName); return result; 

This is the response header if it gives any clues:

Cache-Control:no-cache
Content-Length:2236480
Content-Range:bytes 0-2236480/*
Content-Type:video/mp4

I believe this is an encoder issue on iOS devices. iOS iPhone devices from what I know, use H.264 mp4 encoding. You should try Baseline level 3 encoding for the videos. You can find more info here .
