Just check if pmOS has the latest gstreamer, and then you can try running it with some simple playbin pipeline. Playbin should automatically select the HW decoder. I used kmssink for testing: gst-play-1.0 --use-playbin3 a.mkv --videosink="queue ! kmssink connector-id=52 palne-id=42 plane-properties=s,zpos=2" (I had to patch the kernel too, because kmssink has trouble selecting a correct plane/connector. But if you'll not use kmssink, you should be fine.) If you want to use it from within some compositor, you'll need to select some other video sink. You'll probably have less trouble if you use some wayland compositor that supports HW planes properly. I don't know many players that use gstreamer (is totem still alive?), so hard to tell what GUI to use.
