感谢您的回复..



实际上我写的（WMV）视频文件（没有音频）IWMWriter来自样本采集器中的BYTE数据。

i想要将音频（来自单独设备的音频流）添加到此视频流中。我尝试将两个流传递给WMAsfWriter（100％工作），也就是说，它用音频写视频文件（wmv）。

但是我只是通过使用这个WMAsfWriter将视频流渲染为实时预览如果我想写一个timeideally videofiles意味着，我需要停止mediacontrol并重新连接WMAsfWriter，然后运行mediacontrol。对于这个方法我暂停我的预览一秒钟，因为mediacontrol停止然后运行。

i需要解决这个问题，请帮助我。

是任何其他编写机器人流的作家，或任何其他手段使用WMAsfWriter而不停止mediacontrol

解决方案

我还没有得到如果你最终得到可以告诉我？
