No worries :) Just let's get this fixed and make indi more awesome.

It's an RGGB bayer camera, but so is the SPC900nc which works fine with indi_v4l2_ccd.

I tried to contain the damage  :

:~/ indiserver -v indi_v4l2_ccd
2014-05-16T19:40:19: startup: indiserver -v indi_v4l2_ccd 
2014-05-16T19:40:19: Driver indi_v4l2_ccd: pid=27044 rfd=3 wfd=6 efd=7

2014-05-16T19:40:19: Driver indi_v4l2_ccd: snooping on Telescope Simulator.EQUATORIAL_EOD_COORD

Next I could connect to indiserver and when i click 'stream on' in
kstars my X server got killed. So much for ulimit protection :-P

The camera/pc/kernel/X chain seems fine because this works OK :
vlc -v --no-audio v4l2:// :v4l2-dev="/dev/video0" :v4l2-width=800 :v4l2-height=600 :v4l2-chroma="YUYV"

Suggestions on how to proceed ?
