[Bug 91281] Tonga VCE 2160p encode fails with BO to small for addr

https://bugs.freedesktop.org/show_bug.cgi?id=91281

--- Comment #1 from Andy Furniss adf.lists@gmail.com --- Now that vaapi is enabled the situation with this is more mixed.

omx still just always fails.

ffmpeg vaapi always works.

gatreamer vaapi fails or works depending on framerate, which is a bit confusing.

For 2160p as long as I say framerate <=30 it works. For 4096x2160 it has to be <=26.

Adding size to the kernel error message shows that the failing size = 2x raw framesize -

[drm:amdgpu_vce_cs_reloc [amdgpu]] *ERROR* BO to small for addr 0x0108fde000 14 13 24883200

Adding debugging to vlVaCreateBuffer doesn't show any difference between working and failing cases - the size requested being one raw frame.
