I built ffmpeg out but cannot decode correctly. maybe hardware not working well?

chipset: rk3566
os: Armbian 23.11.0-trunk Lunar

[h264_rkmpp @ 0x55969d1fe0] Failed to initialize MPP context (code = -1).
[h264_rkmpp @ 0x55969d1fe0] Failed to initialize RKMPP decoder.
Stream mapping:
Stream #0:0 -> #0:0 (h264 (h264_rkmpp) -> h264 (h264_rkmpp))
Error while opening decoder for input stream #0:0 : Unknown error occurred

mpp requires vendor(rockchip) kernel.
if you are on vendor kernel, you can check why mpp is complaining from journalctl -f
