Hi Laurent In the mt9p031 driver, the picture can be flipped either horizontally or vertically by using the according V4L2 controls. This can be done at runtime. I have noticed, that flipping the picture will change the bayer-pattern. So if I flip horizontally and vertically to get a 180 degree rotation the bayer pattern changes from V4L2_MBUS_FMT_SGRBG12_1X12 to V4L2_MBUS_FMT_SGBRG12_1X12 I'm not sure how the patch should look like... The format code could be adapted accordingly to the flipping, but how does the userspace notices this change? The user could issue another get_format. But what about the omap3isp-pipe? Concrete: What should I do to configure a streaming pipe with a flipped image? Flip the image on the v4l-subdev and then build the pipe? Is there a chance to propagate the format change through the pipe during streaming? Thanks for your clarification!
