Video streams allow you to quickly and easily see what your robot is seeing and greatly aid in teleoperation. Formant supports USB and IP video streams via Real-Time Streaming Protocol (RTSP) and Real-Time Messaging Protocol (RTMP).
This guide will teach you how to configure a USB or IP video stream on your device.
- In Formant, in the upper-left corner, open the menu and click Settings.
- Click Devices, and then click on the device you want to configure.
- Click the Telemetry tab, and then click Add Stream.
- Click Hardware Video. This will open the New Hardware Video Stream configuration window:
|Telemetry stream name
|Give the stream a name.
|If ON, this stream will store data locally on your device, and only upload data to Formant when you click Retrieve on-demand data.
Rate limit controls the rate at which datapoints are added to the on-device buffer. For more information, see On demand streams.
If OFF, this stream will ingest periodically.
Rate limit controls the rate of data ingestion.
|Quality of the video
|Select your video quality. Higher video quality requires more bandwidth.
The next few options depend on whether you are configuring a USB camera, or an IP camera over RSTP or RTMP.
For USB devices, you can simply enter the path to the device file:
|Video Hardware path
|Enter the path to the Linux device file. This dropdown will auto-populate with devices detected by Formant.
Once configured, the Formant agent will automatically read the image stream from the selected USB camera, encode it to
H.264, and ingest it as a video stream.
Formant supports IP cameras via RTSP and RTMP, as well as the ONVIF protocol.
|Video RTSP URI
|Enter the URI of your camera in the following format:
|Set this to YES if the video has any encoding other than H264.
|Supports ONVIF (RTSP only)
|Set this to YES if your camera supports the ONVIF protocol.
|Enter the username to access your camera.
|Enter the password to access your camera.
You can add an audio source to your video stream:
|Audio Hardware name
|Enter the name of the audio device you want to associate with this video stream.
Add tags to your video stream using the following options:
|Add tags (e.g.
key: value) (optional)
|Add tags to each datapoint of this stream. For more information on tags, see Configure access levels.
When you're finished configuring your stream, click Done, and then Save.
Once you've added a stream to your device, your next step is to add it to a view in Formant.
Add the streams you want to visualize, and then move on to Viewing data in Formant.
