Well, you could use some app to show the snaps that v4l2grab takes. Yeah, compiling v4l2gl on N9 can indeed be complex. I suspect that it shouldn't hard to compile xawtv there (probably disabling some optional features). > Umm, and it looks like libv4l can not automatically convert from > GRBG10.. and if it could, going through RGB24 would probably be too > slow on this device :-(. I suspect it shouldn't be hard to add support for GRBG10. It already supports 8 and 16 bits Bayer formats, at lib/libv4lconvert/bayer.c (to both RGB and YUV formats). How it would preform is another question ;) > > IMO, the above belongs to a separate processing module under > > lib/libv4lconvert/processing/ > > Is there an example using autogain/autowhitebalance from > libv4lconvert? Well, if you plug a USB camera without those controls, it should automatically expose controls for it, as if the device had such controls. Thanks, Mauro
