如何从 Windows 接收 MPEG-TS 多播
目前，我们拥有一个将实时视频编码为 MPEG-TS 多播流的系统，由带有 STB 的电视接收。 除了电视之外，我们还希望将视频嵌入到我们的 Windows 应用程序中。
我知道 VLC 将接收流，但更喜欢一种可以嵌入现有应用程序而无需玩窗口移动游戏的解决方案，以及一种没有许可问题的解决方案。 我意识到这可能意味着我没有在寻找免费的解决方案，这很好，在合理范围内。
有人知道这方面有什么好的产品吗？ 要么是一些易于使用的东西，要么是 WMP 的插件。
We currently have a system with live video encoded to an MPEG-TS multicast stream, being received by televisions with STBs. In addition to televisions we'd like to embed the video in our Windows application.
I know that VLC will receive the stream, but would prefer both a solution that I can embed in an existing application without playing window moving games, and one without licensing problem. I realize that likely means that I'm not looking at a free solution, that's fine, within reason.
Anyone know of a good product for this? Either something easy to use, or a plug-in for WMP.

您需要开发一个简单的 DirectShow 过滤器，用于侦听给定端口并仅传递它收到的每个数据包。
我手边没有示例，但它非常简单，只有几百行代码。
然后，您只需将此过滤器连接到能够解码
传输流的MPEG2 解复用器即可。首先想到的是
NVidia和Elecard，尽管前一个在调试器下无法连接。然后，将
多路分解器连接到解码器，最后连接到渲染器。解复用器和解码器可以很好地处理实时流问题，您只需捕获 UDP 数据包并将其发送给它们即可。
由于许可问题，
MPEG2解码器无法免费（ffmpeg和VLC违反了许可），因此您必须购买解码器。访问 http://elecard.com，他们有一系列不错的
MPEG2产品。You'll need to develop a simple
DirectShowfilter that listens on a given port and just passes down every packet it had received.I don't have a sample handy, but it's really simple, several hundreds lines of code.
Then you just connect this filter to an
MPEG2 Demultiplexercapable of decodingtransport stream.NVidiaandElecardcome to mind first, though the former one does not connect under debugger.Then you connect the
demultiplexerto thedecoderand finally to therenderer.The demultiplexers and decoders handle the live stream issues well, you just capture the
UDPpackets and send down to them.Due to licensing issues,
MPEG2decoders cannot be free (ffmpegandVLCviolate the license), so you'll have to buy the decoder.Visit http://elecard.com, they have a nice range of
MPEG2products.扩展 Quassnoi 的答案...
您可以查看 Haali Media Splitter 来充当“MPEG2 解复用器。” 这是一个过滤器，只是将压缩的视频和声音从传输流中提取出来，所以我猜它不存在任何许可问题。 大多数配备 DVD 播放器的 PC 都已经安装了经过许可的 DirectShow MPEG2 解码器，因此您可以只使用已安装的解码器（或者如果您确实想安全的话，可以从 elecard 等地方购买许可证）。
当您开发 DirectShow 应用程序时，您可能会发现 Monogram GraphStudio设计过滤器链的有用工具。
Expanding on Quassnoi's answer...
You might check out the Haali Media Splitter to act as a "MPEG2 Demultiplexer." This is a filter that just pulls the compressed video and sound out of the transport stream, so I'm guessing it doesn't have any licensing issues. Most PCs with a DVD player on them already have a licensed DirectShow MPEG2 decoder, so you can probably just use one that's already installed (or purchase a license from a place like elecard if you really want to be safe).
As you are developing your DirectShow application, you might find Monogram GraphStudio to be a helpful tool in designing the filter chains.
