Building ffmpeg is non-trivial for beginners. You can use a pre-built binary instead.

thank you very much !!! use Rockchip-FFmpeg-Builds can work !
i have a question: the drawtext defaults to using CPU to overlay watermarks, will we consider using GPU to add watermarks in the future
from ffmpeg-rockchip.
This is beyond what MPP/RGA runtime can support.
You can use the following command to achieve zero-copy, but the text will still be rendered by the CPU.
-vf "scale_rkrga=format=nv12,hwmap,format=nv12,drawtext=...,hwmap"
