GStreamer got some > support, but it's mostly focused on CSC and Scaling (flipping should work, but > rotation is not implemented). But I'm not aware of anything else, hence asking. Rotation orks with gstreamer by tweaking the rotation control manually and forcing the reversed height/width after the v4l2convert. Apart that, I made it works with the LVGL UI library to accelerate buffers switching and blitting on the DRM buffers.
