Comment (by Snowfall):
As stated in the Wiki, you need VCN, but your APU only has UVD.
VCN is RDNA1 and newer, so Ryzen 6000+ with a few exceptions...
The whole feature combination thingy is binary math with a little twist at
the end:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17994/diffs#21d3248ae81f9ef9bebc99e617fcdaea163a6229
Which comes down to:
VBAQ=16, pre-encode=8, quality-preset=4, balanced-preset=2, speed-preset=0
And at the end set the validity bit (bit0) to 1.
For quality + pre-encoding without VBAQ:
4 (quality) + 8 (pre-encode) + 1 (validity bit) = 13
