推荐答案

目前尚不清楚您是否正在使用未加密的DVD.为了这个答案，我假设你是.

It isn't clear whether or not you are using an unencrypted DVD. For the sake of this answer, I'm going to assume you are.

IMediaDet使用Sample Grabber过滤器执行其大部分操作.不幸的是，示例采集卡不支持 VIDEOINFOHEADER2 此处所示的格式.某些MPEG-2解码器将仅使用VIDEOINFOHEADER2格式，从而导致无法连接Sample Grabber和IMediaDet.

IMediaDet uses the Sample Grabber filter to perform most of its operations. Unfortunately the Sample Grabber doesn't support the VIDEOINFOHEADER2 format as indicated here. Some MPEG-2 decoders will only use the VIDEOINFOHEADER2 format, thus preventing the Sample Grabber from connecting, and IMediaDet from working.

我确实知道Elecard的MPEG-2解码器可用这里能够同时输出VIDEOINFOHEADER和VIDEOINFOHEADER2.因此，它与IMediaDet兼容，并且应该能够完成您想要的操作.

I do know that the MPEG-2 decoder from Elecard available here is able to output both VIDEOINFOHEADER and VIDEOINFOHEADER2. It is thus compatible with IMediaDet and should be able to accomplish what you want.
