media: v4l2-ctrls: Add new V4L2_H264_DECODE_PARAM_FLAG_P/BFRAME flags

2022-03-07T11:17:02+00:00

Add new V4L2_H264_DECODE_PARAM_FLAG_P/BFRAME flags that are needed by
NVIDIA Tegra video decoder. Userspace will have to set these flags in
accordance to the type of a decoded frame.

media: i2c: isl7998x: Add driver for Intersil ISL7998x

2022-03-03T22:27:10+00:00

Add driver for the Intersil ISL7998x Analog to MIPI CSI-2/BT656 decoder.
This chip supports 1/2/4 analog video inputs and converts them into
1/2/4 VCs in MIPI CSI2 stream.

This driver currently supports ISL79987 and both 720x480 and 720x576
resolutions, however as per specification, all inputs must use the
same resolution and standard. The only supported pixel format is now
YUYV/YUV422. The chip should support RGB565 on the CSI2 as well, but
this is currently unsupported.

media: allegro: add control to disable encoder buffer

2021-10-20T14:56:40+00:00

The encoder buffer can have a negative impact on the quality of the
encoded video.

Add a control to allow user space to disable the encoder buffer per
channel if the VCU supports the encoder buffer but the quality is not
sufficient.

media: v4l2-ctrls: Add V4L2_CID_NOTIFY_GAINS control

2021-09-30T08:07:46+00:00

We add a new control V4L2_CID_NOTIFY_GAINS which allows the sensor to
be notified what gains will be applied to the different colour
channels by subsequent processing (such as by an ISP), even though the
sensor will not apply any of these gains itself.

For Bayer sensors this will be an array control taking 4 values which
are the 4 gains arranged in the fixed order B, Gb, Gr and R,
irrespective of the exact Bayer order of the sensor itself. The use of
an array makes it straightforward to extend this control to non-Bayer
sensors (for example, sensors with an RGBW pattern) in future.

The units are in all cases linear with the default value indicating a
gain of exactly 1.0. For example, if the default value were reported as
128 then the value 192 would represent a gain of exactly 1.5.

Replace BIT() in v4l2's UPAI header with _BITUL(). BIT() is not defined
in the UAPI headers and its usage may cause userspace build errors.

media: uapi: move MPEG-2 stateless controls out of staging

2021-05-23T17:21:31+00:00

Until now, the MPEG-2 V4L2 API was not exported as a public API,
and only defined in a private media header (media/mpeg2-ctrls.h).

After reviewing the MPEG-2 specification in detail, and reworking
the controls so they match the MPEG-2 semantics properly,
we can consider it ready.
