## 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](https://gstreamer.freedesktop.org/data/pkg/windows/1.10.2/gstreamer-1.0-x86-1.10.2.msi) [Gstreamer 64-Bit Windows](https://gstreamer.freedesktop.org/data/pkg/windows/1.10.2/gstreamer-1.0-x86_64-1.10.2.msi)

Use the following commandline:

```bash
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>

**GstreamerHUD:**

Another Option is GStreamerHUD, see Github page here: <https://github.com/MovLab2/GStreamerHUD>
