v3:
* Patch1: In V2 version of SetInputType tests, I forgot to use index i in the for loop, this version fixes it. And then I found that some subtypes will fail on Windows, I tried many many times with different settings of VIDEOINFOHEADER but they still fails. I don't think it's worth wasting time on it. So I have to skip them for now. * Patch2: Implement wmv format to caps. Remove duplicate majortype setting. * Patch3: Change `wg_format` to `input_format`.
