Just ran AV1 and VP8 tests locally. VP8 completely fails (0/61) as the upda=
te
rejects the VP8 controls in mtk_vdec_s_ctrl. As for AV1, it completely regr=
essed
(0 success, there is "invalid tge_size" kind of errors). I've been testing =
with
the upstream firmware since you didn't mention any firmware update (md5 is
52d11ed015d4e2f6d4e9ce9a8fcf20e3).

You can retrace my step using this kernel and normal Debian OS:
