Scaling affects color output about ffmpeg-rockchip

[jagheterfredrik]

Thanks a bunch for the pointer to YUView! It's being displayed in the wrong resolution (1920x1080) and therefore not showing correctly. At the right size it shows fine after scaling. Thank you again for your work on ffmpeg+rockchip 👍

I can't reproduce your issue. Please dump the rawvideo as file and check with the YUView tool.

ffmpeg -hwaccel rkmpp -hwaccel_output_format drm_prime -i INPUT -an -sn \
-vf scale_rkrga=format=yuv420p:w=1280:h=720,hwmap=mode=read,format=yuv420p \
-f rawvideo -vframes 500 -y /tmp/out.yuv
