Unable to read camera feed from GoPro

[HZWang96]

Hi @cheng-chi,

I have connected my GoPro camera to the Elgato capture card (micro HDMI from GoPro media mod -> 'HDMI in' on Elgato capture card) and connected the Elgato capture card to my workstation PC (USB type C from Elgato capture card -> USB 3.0 on workstation PC). I have checked that I able to get an output from the Elgato capture card (I attached an HDMI cable to 'HDMI out' and displayed the output to my monitor). However, I am unable to read the output from the Elgato capture card on my workstation PC (OpenCV window is black).

I have also confirmed that my workstation PC is able to detect the Elgato capture card (the path displayed is '/dev/v4l/by-id/usb-Elgato_Elgato_HD60_X_A00XB32721NNWB-video-index0').

Do you know what might be the source of the problem? Thanks in advance for your help!
