自定义虚拟视频捕获设备 [英] Custom virtual video capture device

问题描述

我是媒体基础和C ++的新手. 但是我想创建一个虚拟的视频捕获设备，它可以被Microsoft Expression Encoder使用. 你能告诉我朝哪个方向看吗? 我认为这应该是异步工作，并且源将是来自移动设备的字节流. 预先感谢.

I`m new to media foundation and C++. But I want to create a virtual video capture device which can be used by Microsoft Expression Encoder. Can you tell me in which direction to look? I think it should be something working asynchronously and a source will be byte stream from mobile device. Thanks in advance.

推荐答案

我认为您不想为此而向Media Foundation寻求帮助. Expression Encoder使用更丰富的API使用DirectShow捕获视频.您需要一个虚拟的DirectShow摄像机，该摄像机已经讨论了多次，并且有一个简单的示例项目开始.

I don't think you want to look into Media Foundation for this. Expression Encoder uses a richer API to capture video with, DirectShow. You want a virtual DirectShow camera, which was discussed multiple times and has a simple sample project to start from.

受支持的USB捕获设备表达式编码器4 :

EE4支持任何提供dshow过滤器的设备. 当前，没有可用的受支持设备的列表， 尽管大多数USB设备的编码器几乎没有问题.

Any device that provides a dshow filter is supported by EE4. Currently, there is no list currently available of supported devices, though most usb devices have little to no issues with encoder.
