it seems you need env variable set?

======


   - Intel
      - You must set ANV_VIDEO_DECODE=1 in your environment to expose video
      decoding
      - Both H.264 and H.265 are supported
      - VK_EXT_descriptor_buffer support, required for Vulkan filters, has
      been merged
      <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/22151> but
      no release includes it yet
   - AMD
      - You must set RADV_PERFTEST=video_decode in your environment to
      expose video decoding
