This section describes how to return capture and compression formats by using the IAMStreamConfig::GetStreamCapsmethod. This method can get more information about accepted media types than the traditional way of enumerating a pin's media types, so you should typically use it instead. IAMStreamConfig::GetStreamCapscan return information about the kinds of formats allowed for audio or video.
