How can I tell if my video capture is working?

1st Official Post

    In live view I'm getting black screen but I read that version 2.1.1 liveview is broken.

    I've gone through setting up Hyperion and WLED and I confirmed that Hyperion is able to pass data to WLED by doing the RGB Byte order wizard and the color is correct.

    I'm using a Pi 4 and currently testing HDMI with my laptop and can confirm that my laptop see the capture card as a second screen.

    The PI can see the capture card and recognize all the resolutions but my LED are not lit.

    Under Capture Devices, is "Enable USB capture" also active?

    Live View is not broken!

    Hyperion receives incorrect hardware values from the system for the grabber.

    v4l2-ctl --all

    v4l2-ctl --list-formats-ext

    Enter the two lines in terminal and post the output.

    Please attach a Hyperion debug log as Hyperion-log.txt

    regards pclin
