But drivers don't agree on the display resolution that should be used as a threshold. Some drivers set V4L2_COLORSPACE_REC709 for 720p and higher while others set V4L2_COLORSPACE_REC709 for anything higher than 576p. Newers drivers use the latter and that also matches what user-space multimedia programs do (i.e: GStreamer), so change the driver logic to be aligned with this. Also, check for the resolution in G_FMT instead unconditionally setting the V4L2_COLORSPACE_REC709 colorspace.
