You're right. Maybe that's the first problem to be fixed though ;-)
Michael, could you try using the "official" (and under development)
BT.656 support code for the OMAP3 ISP driver ? I've just pushed the
branch to git://linuxtv.org/pinchartl/media.git omap3isp/bt656
Laurent,
I did try this kernel and it does not work either - but with a different
error.
Any Idea?
Michael
