Gstreamer

Use an RTP caps declaration and depayloader that match the active stream codec. Verify the Ground forwarding destination and port. Use the examples below as H.264 starting points when that codec is selected.

Displaying the video stream via GStreamer

Connect your device either via USB Tethering, Wifi-Hotspot or Ethernet-Hotspot to the GroundPi.

Windows:

Gstreamer 32-Bit Windows Gstreamer 64-Bit Windows

Use the following commandline:

gst-launch-1.0.exe udpsrc port=5000 ! h264parse ! avdec_h264 ! autovideosink sync=false

Set FORWARD_STREAM=raw in openhd-settings-1.txt to send a raw h264 stream

Some people reported the necessity to add the gst-launch-1.0.exe application to their firewall exception list, see this video for more info: https://www.youtube.com/watch?v=eHCfyWhEAvI
