copied!<p>It seems that JW Player figures out the kind of file to play based on the file extension in the <code>file</code> option. Because you are streaming these from disk, via an ASPX page, you don't have one.</p> <p>The following is how I got this working with JW Player 6 (using mp3s - I didn't have any mp4s handy):</p> <pre><code>jwplayer("player1").setup({ flashplayer: "/jwplayer/jwplayer.flash.swf", file: '/Streamer.ashx', height: 340, width: 388, type: 'mp3' }); </code></pre> <p>The key was the use of <code>type</code> to indicate what kind of file was on the other end. The only reference I can offer for this is <a href="http://www.longtailvideo.com/support/forums/jw-player/setup-issues-and-embedding/74/php-http-streaming" rel="nofollow noreferrer">here</a>: it dates back to 2007, but I couldn't seem to find mentions of <code>type</code> in the documention.</p> <p>Inspired by: <a href="https://stackoverflow.com/questions/4399728/how-do-i-stream-flv-files-from-sql-database">How do I stream .flv files from SQL database</a>, I implemeted an HTTP handler to do the streaming:</p> <pre><code>public class Streamer : IHttpHandler { public void ProcessRequest(HttpContext context) { string filePath = "my file path"; byte[] buffer = File.ReadAllBytes(filePath); context.Response.Clear(); context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetLastModified(DateTime.Now); context.Response.AppendHeader("Content-Type", "audio/mpeg3"); context.Response.AddHeader("Content-Disposition", "attachment;filename=file.mp3"); context.Response.AppendHeader("Content-Length", buffer.Length.ToString()); context.Response.BinaryWrite(buffer); } public bool IsReusable { get { return false; } } } </code></pre> <p>Note that an ASPX page would probably work fine as well, though handlers are more appropriate for this kind of task (and should be more efficient as they don't have a page cycle).</p> <p>Reading the whole file into memory isn't ideal, but it sufficed for proving the concept.</p>
