ioctl CEC_TRANSMIT failed using pyCecClient #592

Closed foxy82 closed 2 years ago

foxy82 commented 2 years ago

I'm running on Rasbian using bullseye and a USB adapter. I compiled using the instructions in the repo.

When I use cec-client things look ok however when I use the python client I get a lot of errors:

Never mind. I was running on. Pi with a USB adapter as the pi isn't the video source I want to work with. The pyCecClient.py found both the usb and the Pi hdmi port and was trying to use the unconnected hdmi port and not the usb adapter.

I changed which adapter was returned in DetectAdapter
