Hi! Thanks Erik! I'm going to review it and merge it. This is the kind of help we're expecting in order to move forward with this driver!
As far as the pitch is concerned, I'm actually looking if there is some register (it should be) in the ov9650 (or the bridge) that the driver should write to, to instruct the cam to return the right picture width. For example, on the mt9v011 sensor, such a functionality is provided by register 0x03. I think that pitch variation should be handled by the hardware (the cam) and *not* by the software, i.e we don't get a picture from the cam then apply a transformation using a software routine before displaying it. The current workaround in LiveCam, that I use to display a proper picture, given a display area of w pixels (let's say 640) and an unknown picture pitch x (greater than W), is that it skips x - w bytes from the bayer stream once the decoder reads w bytes/pixels. You can then apply a bayer decoder to recover the missing color components using interpolation. That's it! :) Thanks again!
