I had understood that the RPi5 HEVC hardware decoder would work with the latest gstreamer (1.28.6), but either this is not the case or I have made an error - there still seems to be a pixel format error(?), see below.
What is the latest status of gstreamer compatabilty - should it work? Is there a patch to make it work?
