播放内存流中的视频文件 [英] Play video file from a memory stream

问题描述

只是想知道这是否可行.我有一个Windows应用程序，该程序从我PC上的.avi文件读取所有字节，然后将其存储在byte []中.所以现在我在内存中有了avi文件，我想直接从内存中将其加载到某种视频播放器控件中.我尝试使用wmplayer控件，显然这是不可能的.我已经阅读了有关使用DirectShow和VLC插件的建议，但是我不知道从哪开始使用这两个插件，而且我还没有看到任何样例代码.有人有任何想法可以详细说明所提到的插件，或者有不同的方法吗?

Just curious to see if this is possible. I have a windows application that reads all the bytes from a .avi file situated on my pc and then stores it in a byte[]. So now I have the avi file in memory, and I want to load it into some sort of a video player control, directly from memory. I've tried using the wmplayer control, apparently this is not possible. I've read suggestion about using the DirectShow and VLC plugins, but I have no idea where to even start using those two and I haven't seen any sample code of this being down. Anybody have any ideas to elaborate on the mentioned plugins, or have a different approach to it?

推荐答案

对于DirectShow，可能需要内存中的源过滤器.我不知道可以使用这种过滤器，但是可以基于

For DirectShow, an in-memory source filter may be required. I am not aware of such a filter being available, but one can be based on Async Filter Sample from DirectShow samples. This is in C++ though.

对于.NET，可以使用 DirectShow.NET 库.一个示例GSSF过滤器可能是内存中源过滤器实现的良好开端.该库还提供DirectShow的COM Interop，可用于构建实例化此过滤器的测试播放器应用程序.

For .NET, DirectShow.NET library can be used. A sample GSSF filter there may be a good start for an in-memory source filter implementation. This library also provides COM Interop for DirectShow that could be used to build a test player application that instantiates this filter.
