Add the new opcodes to cec.h.rst.exceptions to avoid documentation build failures. Signed-off-by: Hans Verkuil Link: https://patch.msgid.link/afe5d8f6cdf2dc030011eaf9acd8f68847d1b8cf.1779115235.git.hverkuil+cisco@kernel.org Signed-off-by: Mauro Carvalho Chehab Message-ID:

media: uvcvideo: Announce deprecation intentions for UVCIOC_CTRL_MAP

2026-05-12T05:30:53+00:00

The UVCIOC_CTRL_MAP lets userspace create a mapping for a custom control. This mapping is usually created by the uvcdynctrl userspace utility. We would like to get the mappings into the driver instead.

media: v4l2-controls: Add control for background detection

2026-05-04T06:35:14+00:00

Add a generic V4L2 boolean control V4L2_CID_MPEG_VIDEO_BACKGROUND_DETECTION that allows encoders to detect background regions in a frame and use fewer bits or skip mode to encode them, potentially reducing bitrate for streams with stationary scenes.

media: uapi: Clarify MBUS color component order for serial buses

2026-03-24T10:58:02+00:00

The subdev format documentation has a subsection describing how to use the media bus pixel codes for serial buses. While it describes the sampling part well, it doesn't really describe the current convention used for the components order. Let's improve that.

media: uapi: HEVC: Add v4l2_ctrl_hevc_ext_sps_[ls]t_rps controls

2026-01-21T13:43:09+00:00

Some hardware (e.g.: Rockchip's rk3588 hevc decoder) need to fully parse the slice header, which cannot be passed with the current controls. There is also no skip method similar as to what can be found in verisilicon HW. The SPS is therefore extended through these 2 new controls, providing the long and short term reference information from the slice header for HEVC decoding. These now controls are similar as what is passed in the Vulkan Video API with the StdVideoH265ShortTermRefPicSet and StdVideoH265LongTermRefPicsSps structures embedded in the SPS struct.
