Hi. How can I automatically adjust a v4l2 device brightness/contrast based on caprured frame properties? I see manual controls in the monitor settings, but does ZM do anything automatically?

I've read that it could be supported at a driver level, but my driver doesn't seem to have it.

Hello Basinilya,

Take a look at an old post how I made this work!

Does ZM store the latest frame anywhere? I know the location is /var/cache/zoneminder in recorder mode, but what about modect mode?

Nevermind, found `zmu -qi`
