Configuring UVAP for Base Demo Mode

To configure UVAP for base demo mode:

$ "${UVAP_HOME}"/scripts/config.sh --stream-uri [STREAM_URI] \
  --demo-mode base

Replace [STREAM_URI] with a valid video file or stream:

An IP camera, for example:
```
rtsp://192.168.0.1/
```
The Stream URI can also contain username and password if the stream is protected, for example:
```
rtsp://username:password@192.168.0.1/
```
A USB device, for example:
```
/dev/video0
```
A pre-recorded video

Multiple streams to be analyzed may be configured by using more --stream-uri [STREAM_URI] parameter pairs, for example:

$ "${UVAP_HOME}"/scripts/config.sh \
  --stream-uri "rtsp://192.168.0.1/" \
  --stream-uri "rtsp://username:password@192.168.0.2/" \
  --stream-uri "rtsp://192.168.0.3/" \
  --demo-mode base

The Stream URI(s) can be changed later by running this configuration script again.

There are more optional parameters for the config.sh script to override defaults. Use the --help parameter to get more details.
