On Navy Flounder there are no hardware decoded video codecs exposed in either vainfo or vdpauinfo, except for MPEG1 and MPEG2.

E.g. vainfo:

vainfo: VA-API version: 1.12 (libva 2.12.0)
vainfo: Driver version: Mesa Gallium driver 21.1.6 for AMD Radeon RX 6700 XT (NAVY_FLOUNDER, DRM 3.41.0, 5.13.6-arch1-1, LLVM 12.0.1)
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD
      VAProfileNone                   :	VAEntrypointVideoProc

I don't know if this is a regression since I've just gotten this card.
