Another rga3 related issue: gstreamer videoconvert can't use RGA3 to convert hdmiin. Here is the pipeline command line I use:
GST_VIDEO_CONVERT_USE_RGA=1 gst-launch-1.0 -e v4l2src device=/dev/video0 ! videoconvert ! waylandsink
After reverting https://github.com/armbian/linux-rockchip/commit/fb4fd88e2200b9b8d135f9ad4b984ea2b5047556 this pipeline will work again. But I haven't found the root cause.

It seems to be related to the use of virt_addr
, I don't use it in my FFmpeg build and use dma_fd
instead, so I don't encounter this problem. Maybe the maintainer of gstreamer plugin @JeffyCN knows more.
Fixes a RGA regression in rkr6 7291693, which broke compatibility with librga 1.9.x and older when using DST over blend/composite and premultiplied alpha.
It's a typo.
When
req_rga->feature.global_alpha_en
is false, it means the API version of userspace librga is 1.9.x and older. And this fix is to make sure it falls back to the legacy behavior.In addition, the source code of librga 1.10 is not yet available to the public at this point.
