      Hi, I have a OSSC with a connected Koryuu, which is always on and producing a signal (regardless of whether a device feeding the Koryuu is).   It also has devices connected to the VGA and SCART ports.  When the VGA or SCART device is powered on, I want the OSSC to switch to that new input, and when it is turned off, fall back to an active input through autoscanning (in this case, the only active input – the S-Video input).  Input autoscan doesn’t’ accomplish this because it stops scanning as soon as the Koryuu signal is detected.  Is there a way to do this and if not, is this sane enough for a feature request?

        This would be more feasible if VGA DDC and SCART blanking voltages were connected and could be used as indicators. I don’t think the ADC chip allows detecting sync from inactive inputs and sync detection of the chip is not very robust either.
