media: uvcvideo: Introduce V4L2_META_FMT_UVC_MSXU_1_5

2025-07-11T17:27:30+00:00

The UVC driver provides two metadata types V4L2_META_FMT_UVC, and
V4L2_META_FMT_D4XX. The only difference between the two of them is that
V4L2_META_FMT_UVC only copies PTS, SCR, size and flags, and
V4L2_META_FMT_D4XX copies the whole metadata section.

Now we only enable V4L2_META_FMT_D4XX for the Intel D4xx family of
devices, but it is useful to have the whole metadata payload for any
device where vendors include other metadata, such as the one described by
Microsoft:
https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/mf-capture-metadata

This patch introduces a new format V4L2_META_FMT_UVC_MSXU_1_5, that is
identical to V4L2_META_FMT_D4XX.

Let the user enable this format with a quirk for now. This way they can
test if their devices provide useful metadata without rebuilding the
kernel. They can later contribute patches to auto-quirk their devices.
We will also work in methods to auto-detect devices compatible with this
new metadata format.

media: v4l2: Add Renesas Camera Receiver Unit pixel formats

2025-07-03T07:04:14+00:00

The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW
data captured from an image sensor without conversion to an RGB/YUV
format. In that case the data are packed into 64-bit blocks, with a
variable amount of padding in the most significant bits depending on
the bitdepth of the data. Add new V4L2 pixel format codes for the new
formats, along with documentation to describe them.

media: v4l2: Add NV15 and NV20 pixel formats

2025-04-08T07:21:21+00:00

Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for
10-bit buffers.

NV15 and NV20 is 10-bit 4:2:0/4:2:2 semi-planar YUV formats similar to
NV12 and NV16, using 10-bit components with no padding between each
component. Instead, a group of 4 luminance/chrominance samples are
stored over 5 bytes in little endian order:

YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes

The '15' and '20' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a
multiple of 8 for NV15 and 4 for NV20.
