发送视频流到web浏览器上的iOS处理程序(.ashx)

Question

我有一个处理程序，返回一个视频文件的视频标签的"源":

    file_info := new System.IO.FileInfo(_Fichero._RutaPrivada);
    bytearr := File.ReadAllBytes(file_info.FullName);
    startbyte := 0;
    endbyte := bytearr.Length;
    //context.Response.Buffer := false;
    context.Response.AddHeader("Accept-Ranges", "bytes");
    context.Response.AddHeader("Content-Type", MimeMapping.GetMimeMapping(file_info.Name).Replace('quicktime', 'mp4'));
    context.Response.AddHeader("Last-Modified", _Fichero._FechaAlta.ToString('R'));
    MD5Enc := new MD5CryptoServiceProvider();
    hash := BitConverter.ToString(MD5Enc.ComputeHash(bytearr)).Replace('-', String.&Empty);
    ETAG := new EntityTagHeaderValue('"' + hash + '"');
    context.Response.AddHeader("ETag", ETAG.Tag);
    if context.Request.Headers["Range"] <> nil then
    begin
      chars := new array of Char(2);
      chars[0] := '=';
      chars[1] := '-';
      range := context.Request.Headers["Range"].Split (chars);
      startbyte := Integer(Convert.ToInt64(range[1]));
      if (range[2] <> nil) and (not range[2].IsEmpty) then
        endbyte := Integer(Convert.ToInt64(range[2]));

      //Set the status code of the response to 206 (Partial Content) and add a content range header.
      context.Response.StatusCode := 206;
      context.Response.AddHeader("Content-Range", String.Format("bytes {0}-{1}/{2}", startbyte, endbyte - 1, bytearr.Length));
    end;
    context.Response.AddHeader("Content-Length", (endbyte - startbyte).ToString);   
    //Finally, write the video file to the output stream, starting from the specified byte position.
    context.Response.OutputStream.Write(bytearr, startbyte, endbyte - startbyte);
    context.Response.OutputStream.Flush;

客户端代码

<video id="video_6546" class="video-js vjs-default-skin" data-setup="{}" preload="auto" controls="controls">    
    <source type="video/mp4" src="/Handlers/PreviewByFile.ashx?PECO=oqkyuz2gwmx4xnick0tfem45"></source>
</video>

此代码在Chrome, Firefox和IE上运行良好。
但在iPhone或iPad的Safari中不工作，视频无法加载
