I'm a rookie in DirectX Show. I have question. How can I capture still images from ASF files or WMV files.
I used to try IMediaDet, but I failed. When I take advantage of IMediaDet::put_Filename, the HRESULT always tells me a VFW_E_CERTIFICATION_FAILURE error. I dunno why. Can anybody tell the how to do the task? Thanks.
(To me, it's a very hard question)
