Black image on Hyperion live view | RPI 5 + Ugreen usb hdmi video capturd card,

  • Hey everyone,

    I have the following setup
    Chromecast 4k into an HDMI splitter (1-in 2-out), that support up to 8k 60hz
    One HDMI into a 4k Samsung tv, works just fine including CEC
    The other HDMI goes into a UGREEN USB HDMI capture card (model: CM489), it goes into a raspberry pi 5 (4gb) with Hyperion

    On Hyperion the USB is recognized but only shows a black image in the live view, I tried almost all the settings but still the same.

    Things I tried:
    - Lowering the Chromecast resolution to 1080p 30hz
    - Connected the USB into a laptop with OBS, managed to capture the image with no issues (MJPEG, 1920x1080, 30fps)
    - Changed the USB power settings on the PI (set usb_max_current_enable to 1)
    - Took an image from the pi (tried a few jpg and yuyv, both jpg could not be viewed, possibly corrupt, the yuyv showed a black image as well

    I am not sure what else to try, any advice would be helpful!
    Thank you all! :)

    Unfortunately, I can't find anything specific when searching for "UGREEN USB HDMI capture card CM489".

    Could you please post the output of...

    usb-devices

    lsusb

    v4l2-ctl --all

    v4l2-ctl --list-formats-ext


    Link would be good too.

  • "Hyperion Settings level Expert and check the hardware settings of the grabber.

    Press Default hardware controls"


    Doing this solved the video capturing issue, thank you!
    The only issue I face now, is that when there is no data, I get a rainbow screen like the one below.

    I assume it's the USB doings?
    This is the usb
