[Motion-user] Frequent brightness changes on snapshots

[Robert R. <rob...@co...>]

Hi,

I have motion 3.2.7 running under Debian sarge. I have

bttv1: detected: Provideo PV143A [card=105], PCI subsystem ID is aa00:1430

4 input 1 bt878 video card and have round robin through 4 inputs. But 
frequently (every few seconds) I have major change in brightness and also it 
travels around for a pixel or two.

I've tried with autobrightness on and off, no go...

How can I workaround that problem ? Is round robin going too fast selecting 
inputs ?

Thanks in advance,

regards,

Rob.
