Hello Josh, I am currently looking at V4L2 and your atmel-isi driver for an AT91 based platform on which I would like the ISI interface to capture the image from a camera and have this image directly output in RGB format at a specific location on the screen (so that it can be nicely integrated into a Qt application for example). At the moment, I grab frames from the V4L2 device to userspace, do the YUV -> RGB conversion manually in my application, and then displays the converted frame on the framebuffer thanks to normal Qt painting mechanisms. This works, but obviously consumes a lot of CPU. >From the AT91 datasheet, I understand that the ISI interface is capable of doing the YUV -> RGB conversion and is also capable of outputting the frame at some location in the framebuffer, but I don't see how to use this capability with the Linux V4L2 and framebuffer infrastructures. Is this possible ? If so, could you provide some pointers or starting points to get me started ? If not, what is missing in the driver ?
