I've not checked all of the VAAPI decoder for consistency, but we don't use
C-style casts in media code. This should be replaced with a static_cast<>().

That said, these don't look like VideoCodecProfiles; vp9_parser defines
kVp9MaxProfile = 4, which would be an H.264 VideoCodecProfile.

     return false;
