Hi Sergio, thanks for your fast reply, it's good to hear that someone already has the issues in mind that I'm talking of. As I mentioned before I haven't done any driver development by now, but maybe it's also a good chance to get a little bit into that now. Currently the one and only real problem with the driver at this time is that the YUYV and YVYU support seems to be broken - it's hard to say because of the heavy over-exposure, but I guess there is something wrong in a conversion or something simple like that. Fixing only this issue (and maybe the auto-exposure) would give us everything we need. However, as soon as you have some time to take a look at that feel free to contact me such that we can further talk about these things.

Currently I'm a bit absorbed by other higher priority tasks, so I haven’t been able to update the driver as fast as I would want. We are working towards enhancing the driver so most of the features be available, but if you have some enhancement suggestion, I'll invite you to do so. I appreciate your time.
