This is a gstreamer plugin developed by UnlimitedIRL to support pulling H264 frames from DJI action cameras

For Rockchip decode on kernel 5.10 use mppvideodec

for Rockchip decode on kernel 6.6 use v4l2slh264dec

Example pipeline to send frames to HDMI output:

gst-launch-1.0 libuvch264src index=0 ! video/x-h264,width=1920,height=1080,framerate=30/1 ! queue ! h264parse ! queue ! v4l2slh264dec ! queue ! videoconvert ! kmssink
