The 16-bit RGB V4L2 4CCs are named based on a little endian byte ordering. If you look at V4L2_PIX_FMT_RGBA444 for instance, we have, in memory bbbbaaaa rrrrgggg If you read that as a 16-bit integer in little endian order, you get rrrrggggbbbbaaaa hence the name RGBA444. > Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> > > > --- > > .../media/uapi/v4l/pixfmt-packed-rgb.rst | 138 ++++++++++++++++++ > > include/uapi/linux/videodev2.h | 6 + > > 2 files changed, 144 insertions(+) > > > > diff --git a/Documentation/media/uapi/v4l/pixfmt-packed-rgb.rst b/Documentation/media/uapi/v4l/pixfmt-packed-rgb.rst > > index 055f9c89e787..b475cbba492f 100644 > > --- a/Documentation/media/uapi/v4l/pixfmt-packed-rgb.rst > > +++ b/Documentation/media/uapi/v4l/pixfmt-packed-rgb.rst > > @@ -139,6 +139,144 @@ next to each other in memory. > > - r\ :sub:`1` > > - r\ :sub:`0` > > - > > + * .. _V4L2-PIX-FMT-RGBA444: > > + > > + - ``V4L2_PIX_FMT_RGBA444`` > > + - 'RA12' > > + > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - a\ :sub:`3` > > + - a\ :sub:`2` > > + - a\ :sub:`1` > > + - a\ :sub:`0` > > + > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - > > + * .. _V4L2-PIX-FMT-RGBX444: > > + > > + - ``V4L2_PIX_FMT_RGBX444`` > > + - 'RX12' > > + > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - > > + - > > + - > > + - > > + > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - > > + * .. _V4L2-PIX-FMT-ABGR444: > > + > > + - ``V4L2_PIX_FMT_ABGR444`` > > + - 'AB12' > > + > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + > > + - a\ :sub:`3` > > + - a\ :sub:`2` > > + - a\ :sub:`1` > > + - a\ :sub:`0` > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - > > + * .. _V4L2-PIX-FMT-XBGR444: > > + > > + - ``V4L2_PIX_FMT_XBGR444`` > > + - 'XB12' > > + > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + > > + - > > + - > > + - > > + - > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - > > + * .. _V4L2-PIX-FMT-BGRA444: > > + > > + - ``V4L2_PIX_FMT_BGRA444`` > > + - 'BA12' > > + > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + - a\ :sub:`3` > > + - a\ :sub:`2` > > + - a\ :sub:`1` > > + - a\ :sub:`0` > > + > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - > > + * .. _V4L2-PIX-FMT-BGRX444: > > + > > + - ``V4L2_PIX_FMT_BGRX444`` > > + - 'BX12' > > + > > + - r\ :sub:`3` > > + - r\ :sub:`2` > > + - r\ :sub:`1` > > + - r\ :sub:`0` > > + - > > + - > > + - > > + - > > + > > + - b\ :sub:`3` > > + - b\ :sub:`2` > > + - b\ :sub:`1` > > + - b\ :sub:`0` > > + - g\ :sub:`3` > > + - g\ :sub:`2` > > + - g\ :sub:`1` > > + - g\ :sub:`0` > > + - > > * .. _V4L2-PIX-FMT-ARGB555: > > > > - ``V4L2_PIX_FMT_ARGB555`` > > diff --git a/include/uapi/linux/videodev2.h b/include/uapi/linux/videodev2.h > > index 4e5222726719..df9fa78a6ab7 100644 > > --- a/include/uapi/linux/videodev2.h > > +++ b/include/uapi/linux/videodev2.h > > @@ -514,6 +514,12 @@ struct v4l2_pix_format { > > #define V4L2_PIX_FMT_RGB444 v4l2_fourcc('R', '4', '4', '4') /* 16 xxxxrrrr ggggbbbb */ > > #define V4L2_PIX_FMT_ARGB444 v4l2_fourcc('A', 'R', '1', '2') /* 16 aaaarrrr ggggbbbb */ > > #define V4L2_PIX_FMT_XRGB444 v4l2_fourcc('X', 'R', '1', '2') /* 16 xxxxrrrr ggggbbbb */ > > +#define V4L2_PIX_FMT_RGBA444 v4l2_fourcc('R', 'A', '1', '2') /* 16 rrrrgggg bbbbaaaa */ > > +#define V4L2_PIX_FMT_RGBX444 v4l2_fourcc('R', 'X', '1', '2') /* 16 rrrrgggg bbbbxxxx */ > > +#define V4L2_PIX_FMT_ABGR444 v4l2_fourcc('A', 'B', '1', '2') /* 16 aaaabbbb ggggrrrr */ > > +#define V4L2_PIX_FMT_XBGR444 v4l2_fourcc('X', 'B', '1', '2') /* 16 xxxxbbbb ggggrrrr */ > > +#define V4L2_PIX_FMT_BGRA444 v4l2_fourcc('B', 'A', '1', '2') /* 16 bbbbgggg rrrraaaa */ > > +#define V4L2_PIX_FMT_BGRX444 v4l2_fourcc('B', 'X', '1', '2') /* 16 bbbbgggg rrrrxxxx */ > > #define V4L2_PIX_FMT_RGB555 v4l2_fourcc('R', 'G', 'B', 'O') /* 16 RGB-5-5-5 */ > > #define V4L2_PIX_FMT_ARGB555 v4l2_fourcc('A', 'R', '1', '5') /* 16 ARGB-1-5-5-5 */ > > #define V4L2_PIX_FMT_XRGB555 v4l2_fourcc('X', 'R', '1', '5') /* 16 XRGB-1-5-5-5 */ > > -- > > Regards, > > > > Laurent Pinchart > >

That fourcc makes no sense for V4L2_PIX_FMT_SGRBG12 and I suspect it was a mistake, but it's been in use since 2014. I think V4L2_PIX_FMT_BGRA444 should get a different fourcc and be backported to 5.2. Can you address this issue?
