I'm not sure what you mean? Only a few RGB format GUID have a different value between MEDIASUBTYPE and MFVideoFormat. The code was converting some YUV formats unnecessarily, and missing other formats that don't need conversion (when they share `MFVideoFormat_Base`).

This is also to make sure the `get_mf_subtype_for_am_subtype` conversion matches the later introduced `get_am_subtype_for_mf_subtype`.
