使用MVC3和的Flowplayer，我有一个设置为获得与下面的标记视频文件的视频播放器： 

<div id="video">
    <div id="video-viewport">
      <!-- The data-ratio is a decimal number represeting the height of the video in proportion to the width -->
      <div class="flowplayer" data-swf="http://releases.flowplayer.org/5.1.1/flowplayer.swf"
        data-ratio="0.417" data-engine="html5" data-keyboard="true" data-native_ipad_fullscreen="true"
        data-volume="0.6">
        <video>
       <!-- By default Flowplayer attempts to use HTML5 video and if it's not
       supported then Flash (9.0+) and MP4 is used. MP4 is enough for
       complete browser support but providing WebM and/or OGG gives you
       broader support for HTML5 video which is the preferred technology. -->
     <!-- MP4 gives a complete cross browser support with the aid of Flash -->
     <source type="video/mp4" src="@Url.Action("GetVideo", "Video", new { id = Model.WebMp4Video.Id })"/>
     <!-- WEBM gives HTML5 video support for the latest Firefox, Chrome and Opera browser -->
      <source type="video/webm" src="@Url.Action("GetVideo", "Video", new { id = Model.WebMVideo.Id })"/> 
     <!-- OGG gives HTML5 support for older versions of Firefox and Opera -->
      <source type="video/ogv" src="@Url.Action("GetVideo", "Video", new { id = Model.OgvVideo.Id })"/> 
      </video>
      </div>
    </div>
  </div> <!--/video-->

在控制器我有这个方法返回的视频： 

    public ActionResult GetVideo(string id) {
                ...
        var cd = new System.Net.Mime.ContentDisposition {
        Inline = false
    };
    FileInfo info = new FileInfo(path);
    Response.AppendHeader("Content-Disposition", cd.ToString());
    return new RangeFilePathResult(MimeType, info.FullName, info.LastWriteTimeUtc, info.Length); 
 }

RangeFilePathResult已经在返回部分缓解生命的救星，这一切工作正常在Firefox和IE，但在Chrome中我得到一个错误频繁：

“之后HTTP标头已经发送服务器不能设置状态”。

而玩家本身崩溃，揭示了页面上出现以下错误：

HTML5：影片未正确编码

我仍然在试图让我的周围部分反应的头，但可能这是因为RangeFileResult设置的状态码206，每个部分缓解？ 或者是有什么事我是缺少在这里？

编辑 ：如果我调试通过RangeFileResult代码，并且还检查在Chrome网络选项卡，我注意到该请求到控制器方法返回部分响应，带有状态之前，只要代码点击这一行：

context.HttpContext.Response.Flush（）;

人们似乎对这个延迟，有时超过10秒，但是当这是完成的repsonse的状态变为206，而通常在视频播放，不过，状态再次变为取消 ，这是当

HTML5：影片未正确编码

视频播放器上显示的消息。

EDIT2：是我得到的repsonses如下（3个回应，第一和第三被取消，第二个有206种状态：

Answer 1:

经过一番紧张的测试（谢谢你的示例项目），它看起来像Chrome在与MP4格式的一些问题。

为了解决这种情况，应该是足够的移动WEBM为第一格式，因此Chrome将它捡起来代替MP4的（IE会跳到MP4所以它也可以工作）： 

<div id="video">
    <div id="video-viewport">
        <div class="flowplayer" data-swf="http://releases.flowplayer.org/5.1.1/flowplayer.swf" data-ratio="0.417" data-engine="html5" data-keyboard="true" data-native_ipad_fullscreen="true" data-volume="0.6">
            <video>
                <source type="video/webm" src="@Url.Action("GetVideo", "Video", new { id = Model.WebMVideo.Id })"/> 
                <source type="video/ogv" src="@Url.Action("GetVideo", "Video", new { id = Model.OgvVideo.Id })"/>
                <source type="video/mp4" src="@Url.Action("GetVideo", "Video", new { id = Model.WebMp4Video.Id })"/>
            </video>
        </div>
    </div>
</div>


Answer 2:

你可以试试这个，它固定我的问题whick似乎同样有你的。 

<script>
    flowplayer.conf={
        engine:'flash'
    };
</script>
