Hi Hans, > I would expect that the combination of v4l2_mbus_framefmt + v4l2_dv_timings > gives you the information you need. About v4l2_mbus_framefmt, you use V4L2_MBUS_FMT_FIXED. I guess you can't find any yuv 24 or rgb 16/24bit format in current v4l2_mbus_framefmt. But a bridge driver working with variable sensors and decoders can't accept this. About v4l2_dv_timings, do I need to set a default timing similar to pick PAL as default standard?
