Hey ChenJaly,
I can confirm the hardware accelerated ffmpeg works correctly for BGR3 (RGB8) pixel format at any custom resolution at full 60 fps. Is there anyway to get the custom gstreamer1.0-rockchip that was included with Introduction to rockchip-multimedia ppa for ubuntu jammy If I can get that built I think I will be able to proceed with my development as we use gstreamer here.
Thanks so much for your fast and helpful reply!
EDIT: I found the following repo but I don’t know if it is the latest of best version for rockchip gstreamer GitHub - Lockzhiner/gstreamer-rockchip
