ok following that, doing the mpp tests, 1080p h264 hardware encoding etc work, but hevc does not, get this error ;

[hevc_rkmpp @ 0xaaaae3ae2aa0] Failed to init MPP context: -1 [vost#0:0/hevc_rkmpp @ 0xaaaae3ae2700] Error while opening encoder - maybe incorrect parameters such as bit_rate, rate, width or height.

It seems something went wrong in your device tree or the source code of rockchip linux kernel (5.10.110, 5.10.160, 5.10.198). Generally speaking, the rkvenc node enables both h.264 and hevc encoder on rk356x chips, so this is unlikely to happen.
