I successfully installed Hyperbion, configured it and run it perfectly. I just noticed one interesting thing I am unable to debug or figure out. When I change anything in configuration and restart the Hyperbion, I see only typical "TV noise" which is captured - instead of original video. And for this noise, the LEDs are blinking, so the LEDs are working.
Does anybody experience similar problem? I needed to restart the RaspberryPi to fix the capture. It looks like the capture HW is unable to capture the source and put the noise as an input.
