Image flip doesn't work too.

I really advise to use v4l2ucp instead.Thanks, I was too lazy to download qt-devel and compile it, but I did it, when you told me v4l2ucp is better. Unfortunately when I started v4l2ucp unclear picture in mplayer window almost disapear, I saw only noise. and spot of bulb I played a lot with v4l2ucp settings, but I can't improve picture - I guess maximal gain is too small, and smaller that gain level without v4l2ucp: http://www.wrzuta.pl/obraz/3COQNheo94/withv4l2ucp before v4l2ucp: http://www.wrzuta.pl/obraz/5xVKppcNAe/withoutv5l2ucp In Windows with identical light conditions I have quite good picture even without turn on night mode http://www.wrzuta.pl/obraz/tUyLLEJFUO/stanard
OK, thanks for the screenshots.Night mode. Hmm that doesn't show up in the datasheets but I'll see if I can put a few options together that increase exposure.
Anyway I'll push the basic code for hv7131r now so other people can at least see that work is being done.
