IDvdInfo2::GetDecoderCaps method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The GetDecoderCaps method retrieves the DVD decoder's maximum data rate for video, audio, and subpicture (in forward and reverse) as well as support for various types of audio (AC-3, MPEG-2, DTS, SDDS, LPCM).
