Test filter using code below:

sudo ~/ffmpeg-rockchip/ffmpeg -init_hw_device rkmpp=hw -filter_hw_device hw -f lavfi -i testsrc2=s=1920x1080,format=yuv420p
-vf hwupload,scale_rkrga=w=1280:h=720:format=nv12 -c:v h264_rkmpp -b:v 4M -maxrate 4M -vframes 1000 -y ./tmp.mp4

and it pops an error like:

I run this on a rk3588s2 chip: radxa rock 5c, i'm not sure is this propblem comes with chip or ffmpeg-rockchip.

I cannot reproduce this issue. Make sure you have followed the tutorials in the wiki and used the mpp and rga branches I provided.

Thanks a lot, i currently use code below to compile ffmpeg-rockchip:

(not following your wiki)

I will try to compile mpp and rga my self.
