Colours inversed using USB grabber / HDMI

  • HI All


    First time installation, I have my hardware setup and capturing live video:

    Host - Raspberry Pi Zero W2
    Input via a HDMI splitter / EDID emulator - HDMI 1 out to tv, HDMI 2 input to usb video capture


    System is operational and I can get through to the host page, view live feed etc - issue I am having is the colour profile of what is being capture, almost appears that the RGB are on the wrong channels.

    I have tried checking the souce output using a tv on the output of splitter thats leading to the PI, this displays correctly.
    I have also tried using multiple resolution, fps and capture profiles, none of which appear to make any difference (bar sharpness of the image).

    Does anyone have any other pointers they might be able to give to test this or ways to improve?


    Thanks

    Andy

  • Hey, bear in mind this is on the capture of the video rather than the output of the LEDs (im yet to get to that bit), are we suggesting resolving the RGB on output will fix the video capture colouring?

    Thanks

    OK, then connect the USB output to a PC and test with VLC, for example.


    Please also write exactly what you use. Hardware, software, etc.
