I'm getting an error when using hardware acceleration for video scale conversion.

This video conversion consumes 80% of one core and there are complaints that this computer is too slow. I run it on Rock 5b with 8GB mem.

Gstreamer is built from the latest radxa/meta-rockchip yocto configuration.

Is there any way to be able to use hardware acceleration for video conversion/scaling?

Also, this is how a simple test output looks like. It supposed to be blocks with solid colors, without horizontal lines and with bright colors. Instead there are some extra lines and missing colors.

sorry, i don't know much about RGA :(

the RGA changes a lot in RK3588 (hardware + kernel driver + userspace lib), it's too hard for me to follow those changes. please mail the RGA maintaner(Yu Qiaowei cerf.yu@rock-chips.com) for more details, i've heard it needs special version of kernel driver and userspace lib to work.

there're lots of branches for librga, i've uploaded some here: https://github.com/JeffyCN/mirrors/branches

maybe the "multi" branch would work for rk3588
