NDI HX support over RPI4

[jbolduc01]

Is there a way to make NDI HX source decoded inside RPI4 using hardware acceleration?
I am using the following pipeline and it is not working:
gst-launch-1.0 ndisrc ndi-name="LPT-JBOLDUC (Intel Iris Xe Graphics 1)" color-format=compressed-v5 ! ndisrcdemux name=demux demux.video ! queue ! h264parse ! v4l2h264dec ! fpsdisplaysink video-sink=fakesink text-overlay=false sync=false -v
When using CPU based decoder, it is working but with poor performance:
gst-launch-1.0 ndisrc ndi-name="LPT-JBOLDUC (Intel Iris Xe Graphics 1)" color-format=compressed-v5 ! ndisrcdemux ! queue ! h264parse ! avdec_h264 ! fpsdisplaysink video-sink=autovideosink text-overlay=false sync=false -v
Thanks!
