This means someone's trying to use an image format (i.e.
ARB_shader_image_load_store image) that's not supported by the backend. Guess
it works OK on AMD, so they just use it... sigh. Looks like it just takes the
fb's format and sticks it into an image. That's definitely not generically OK.
Maybe the compute pipeline just needs to check if it's running on radeonsi,
since it's not a generic gallium API usage.
Just noticed that mpv supports VA-API -- I'll try using that to test it later.</pre>
