My FFmpeg 6.0.1 (not the latest 6.1) on Tumbleweed-Slowroll has 
currently only AV1 QSV Decoder (no encoder):

    ffmpeg -codecs -hide_banner | grep av1
      DEV.L. av1                  Alliance for Open Media AV1 (decoders:
    libdav1d libaom-av1 av1 av1_cuvid av1_qsv ) (encoders: libaom-av1
    librav1e libsvtav1 av1_nvenc av1_amf )
      DEAIL. wmav1                Windows Media Audio 1

All Intel GPU media users are encouraged to switch to VPL to take 
advantage of hardware capabilities as soon as they become available.
The switch to VPL from Media SDK in FFMPEG, is simple. Just substitute 
‘--enable-libvpl’ instead of ‘--enable-libmfx’
