Using TinyPilot with Raspberry Camera / without HDMI

    Hello,

    I have a device which does not support HDMI or VGA output. I thought I could replace the HDMI Adapter Board with the Raspberry Pi camera - however it does not seem to be plug-and-play - I still get "no signal" in the web ui.
    Is there any trick to it?

    Additionally the mouse does not seem to work when the HDMI is not connected. Not sure if this is the device or the fact that there is no Video signal. The Keyboard seems to be recognized.

    It would be great if you could provide any advice on this.

      The camera has different settings from the HDMI capture board, which you can find here:

      https://github.com/tiny-pilot/ustreamer/tree/1dafb54621515741ff2d76edc882de77033e06b0#raspberry-pi-camera-example

      You'd need to modify the uStreamer settings.

      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
      ...
      

      That's where you'd apply changes for PiCamera settings.

      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
      

      Additionally the mouse does not seem to work when the HDMI is not connected. Not sure if this is the device or the fact that there is no Video signal. The Keyboard seems to be recognized.

      Some systems behave differently when virtual media is enabled. Can you try disabling virtual media?

          Alternately can you use an adapter for whatever video output your device does have, such as DVI-D to HDMI or DisplayPort to HDMI?
