Blank screen on reboot

By Justin Kumpe @jakumpe2021-02-24 21:51:20.858Z

When I reboot my server tinypilot goes to a black screen and I have to reboot tinypilot to get video back. Any way to fix this?

    This is with the hobbyist kit, correct?

    The HDMI to USB dongles can unfortunately be temperamental with certain machines.

    If you SSH in and restart just the streaming service (uStreamer), does that bring back the video?

    sudo service ustreamer restart

      Yes, this is the hobbyist kit. No, restarting ustreamer does not help.

        The other option is to reset the USB port. It's a bit tricky to set up, but some of my users have had success with this tool:

        Hi, i also experience same issue. no problem while it was on windows' session.
        i will get blank screen whenever i reboot and any this pre-OS (such BIOS etc..) will remain blank.

        I applied this sudo service ustreamer restart on SSH however it doesnt help

        My Setup: raspberry pi4 + TinyPilot Power Connector splitter

          What video capture hardware are you using?

              Hi @michael do you have any specific chipset/brand that i can give try for this? thanks.

                Many of the HDMI chips are unbranded, but you can recognize them by photo. Any of the capture chips marked as "Tested compatible (@mtlynch)" on this page should work:
