The driver don't take into account the differences between packed, semi planar and multi planar formats when calculating the pixel format bytes per lines and image size values. This makes GStreamer to fail when the following formats are used NV12, NV21, NV16, NV61, YV12, I420 and Y42B: "gst_video_frame_map_id: failed to map video frame plane 1" Nicolas suggested to use the logic found in the Exynos FIMC v4l2 driver since does this correctly. So this patch changes the bytes per line and image size calculation according to what's done in this media driver. After this patch most supported formats work correctly. There are still issues with the NV21 and NV61 formats, but that seems to be a separate problem since NV12 and NV16 work and these formats use the same values. So this can be fixed as a follow-up and shouldn't be a blocker for this change that improves the driver's support.
