[zyy]

I have the DV video Decoder of Microsoft. How can i get one frame buffer of a given DV avi by using it? Is there any fuction to call?

The way now i am using is write a source filter and a render filter. Set one frame raw dv data into the source filter and run the graph, I will get one frame uncompressed frame in the render filter. Is there any easy way to do this job?

Thanks alot
