用于多个平滑流媒体元素的平滑流媒体播放器
当前版本的 Silverlight Media Framework 是否提供具有多个平滑流媒体元素的流式传输？例如，我想要一个可以播放屏幕截图的播放器，另一个可以播放人类的播放器，就像这个示例 微软 PDC 。可以用SMF来做吗？ 是否有任何可用的解决方案/示例允许我在播放器上同时流式传输多个视频？
感谢您的建议。
Does current version of Silverlight Media Framework provides streaming with multiple smooth streaming media elements? For example, I would like to have a player that could play for a screen capture and another one for human just like this example Microsoft PDC . Is it possible to do with SMF?
Are there any solutions/examples available which allow me to simultaneously stream multiple videos in on player?
Thanks for suggestion.

但是，我必须说，我实际上还没有看到任何人使用它，也没有看到任何如何实现它的代码示例。
但值得注意的是，对于 Microsoft PDC，您所观看的实际上是单个流。相机和屏幕捕获源简单地组合到该布局预编码中（通过视频切换器或可能是 Wirecast 等软件编码器）。它需要在“生产”方面做更多的工作，但使您的部署变得更加容易，并且您不需要 2 倍的编码能力。
There is a multi-cam demo sample in the IIS showcase, which is similar to the effect you are looking for...

However, I must say I have not actually seen anyone use this yet, nor any code samples in how to achieve it.
It's worth noting, though - that in the case of Microsoft PDC, what you are watching is, in fact, a single stream. The camera and screen capture sources are simply combined into that layout pre-encoding (via either a video switcher or perhaps a software encoder like Wirecast). It requires a little more work on the "production" side, but makes your deployment a lot easier, and you don't need 2x the encoding power.
