@JeffyCN I would like to run more than one instance of rkximagesink, but I get flickering. When one instance is drawing the other is blanking.

Say I have three cameras, but can't run it.

rkximagesink based on kmssink, which is using drm plane to display. so you need to specify different planes(if there are any) for multiple instanse.

check gst-inspect-1.0 kmssink for more details

normally we would prefer hacked xvimagesink(a little slower)
