Hello,
Finally, I can read raw HDMI data using the C790 Board. https://geekworm.com/products/c790
I have created this basic script to enable the C790 Module.
The command line is:
sh sh enablevid.sh number of the media device
ie: sh enablevid.sh 0
after complete this command you should be able to run and display the live data from the HDMIQuestion:
How do I get in the script the correct media device?
How do I access the /dev/video0 using Python and CV2? It doest detect as a camera and I can't use cap = cv2.VideoCapture(0)
Problems:
how do I fix the colors?
