Description Kdwk 2023-08-19 02:52:44 PDT 
With the environment variable GST_PLUGIN_FEATURE_RANK=nvav1dec:MAX,nvh264dec:MAX,nvh265dec:MAX,nvjpegdec:MAX,nvmpeg2videodec:MAX,nvmpeg4videodec:MAX,nvmpegvideodec:MAX,nvvp8dec:MAX,nvvp9dec:MAX set, video playback uses the same CPU % as before, and nvtop doesn't show the media decode engine being used.

On Intel GPUs max-ranking va elements work. nvdec elements also work in video players like Clapper.

I'm not so sure about this any more. I've looked at the CPU usage playing a video in Clapper and it uses the same % of CPU as Web, even though it says it uses nvdec
