Video brightness little dull

What model TinyPilot are you using?

It's not possible to adjust the brightness on the Voyager.

The Hobbyist kit does support changing the brightness.

To begin, open the ustreamer.service file:

nano /lib/systemd/system/ustreamer.service

You'll see an ExecStart line that begins like this:

ExecStart=/opt/ustreamer/ustreamer \
  --host 127.0.0.1 \
  --port 8001
...

At the end of the ExecStart section, add the following line and save the file. You can choose different values for brightness between -128 and 127 (the default is -11).

  --brightness 30

To apply the changes to the video stream, run this command after saving the ustreamer.service file:

sudo systemctl daemon-reload && sudo service ustreamer restart

You can try again for different --brightness settings if that doesn't work.

Once you find a setting you like, you can save it to settings so that it persists across software updates. Add the following to your /home/tinypilot/settings.yml file:

ustreamer_brightness: 30
