## 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>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://openhd.gitbook.io/open-hd/master/ground-station-software/gstreamer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
