How to get html content from a webview?

How can I get an HTML 5 media player to stream video content as opposed to downloading the video file?

• My project has an existing silverlight player that streams ismv video files and the technology I believe is behind that is IIS media services. I want to change the silverlight player with a HTML5 player. The video files I will use are mp4. How can I stream this video content with the HTML 5 player as opposed to downloading the whole file when playing the video.?

  I recently needed this, and found that a simple .Net script did the trick of streaming H.264/AAC MP4 files.  I also found that this method is very processor and memory intensive. First, make a folder called videos at the root of your web server, and put your mp4s in it. Next, make a file called "streammp4.ashx" at the root of your web server and insert this code into it. <%@ WebHandler Language="C#" Class="streammp4" %> using System; using System.Web; using Page on system.io; using System.Collections.Generic; public class streammp4 : IHttpHandler { private void RangeDownload(string fullpath,HttpContext context) { long size,start,end,length,fp=0; using (StreamReader reader = new StreamReader(fullpath)) { size = reader.BaseStream.Length; start = 0; end = size - 1; length = size; context.Response.AddHeader("Accept-Ranges", "0-" + size); if (!String.IsNullOrEmpty(context.Request.ServerVariables["HTTP_RANGE"])) { long anotherStart = start; long anotherEnd = end; string[] arr_split = context.Request.ServerVariables["HTTP_RANGE"].Split(new char[] { Convert.ToChar("=") }); string range = arr_split[1]; if (range.IndexOf(",") > -1) { context.Response.AddHeader("Content-Range", "bytes " + start + "-" + end + "/" + size); throw new HttpException(416, "Requested Range Not Satisfiable"); } if (range.StartsWith("-")) { anotherStart = size - Convert.ToInt64(range.Substring(1)); } else { arr_split = range.Split(new char[] { Convert.ToChar("-") }); anotherStart = Convert.ToInt64(arr_split[0]); long temp = 0; anotherEnd = (arr_split.Length > 1 && Int64.TryParse(arr_split[1].ToString(), out temp)) ? Convert.ToInt64(arr_split[1]) : size; } anotherEnd = (anotherEnd > end) ? end : anotherEnd; if (anotherStart > anotherEnd || anotherStart > size - 1 || anotherEnd >= size) { context.Response.AddHeader("Content-Range", "bytes " + start + "-" + end + "/" + size); throw new HttpException(416, "Requested Range Not Satisfiable"); } start = anotherStart; end = anotherEnd; length = end - start + 1; fp = reader.BaseStream.Seek(start, SeekOrigin.Begin); context.Response.StatusCode = 206; } } context.Response.AddHeader("Content-Range", "bytes " + start + "-" + end + "/" + size); context.Response.AddHeader("Content-Length", length.ToString()); context.Response.WriteFile(fullpath, fp, length); context.Response.End(); } public void ProcessRequest(HttpContext context) { string filename = context.Request["source"]; string mimetype = "video/mp4"; string fullpath=context.Server.MapPath("videos/"+filename); if (Page on system.io.File.Exists(fullpath)) { context.Response.ContentType = mimetype; if (!String.IsNullOrEmpty(context.Request.ServerVariables["HTTP_RANGE"])) { RangeDownload(fullpath,context); } else { long fileLength = File.OpenRead(fullpath).Length; context.Response.AddHeader("Content-Length", fileLength.ToString()); context.Response.WriteFile(fullpath); } } else { throw new HttpException(404, "Video Not Found Path:"+fullpath); } } public bool IsReusable { get { return false; } } } Finally, make a file called index.html and put this into it <video src="sreammp4.ashx?source=myfile.mp4" width="640" height="480" controls></video>
