What to test:

• Create fakesrc h265 UDP and receive via GStreamer
• Create fakesrc h265 RTSP and receive via GStreamer
• Create fakesrc h265 UDP and receive via QGC
• Create fakesrc h265 RTSP and receive via QGC
• Create fakesrc h265 UDP or RTSP and receive via WebRTC
• Redirect from an IP camera h265 stream and receive via WebRTC
• Redirect from an IP camera h265 stream (RTSP) and receive via QGC

To receive from UDP:

gst-launch-1.0 -vc \
    udpsrc address=127.0.0.1 port=5600 close-socket=false auto-multicast=true \
    ! application/x-rtp, payload=96 \
    ! rtph265depay \
    ! avdec_h265 std-compliance=normal \
    ! videoconvert \
    ! autovideosink sync=false

To receive from RTSP:

gst-launch-1.0 -vc \
    rtspsrc location=rtsp://0.0.0.0:8554/0 latency=0 \
    ! application/x-rtp, payload=96 \
    ! rtph265depay \
    ! avdec_h265 std-compliance=normal \
    ! videoconvert \
    ! autovideosink sync=false

Useful to check if the system supports decoding:

1. open video_demo_hevc
2. open chrome://media-internals
