does the same for the EAV (End of Active Video) code.
- Insert Video Guard Band
adds 4 columns of pixels with the HDMI Video Guard Band code at the
left hand side of the image. This only works with 3 or 4 byte RGB pixel
formats. The RGB pixel value 0xab/0x55/0xab turns out to be equivalent
to the HDMI Video Guard Band code that precedes each active video line
(see section 5.2.2.1 in the HDMI 1.3 Specification). To test if a video
receiver has correct HDMI Video Guard Band processing, enable this
control and then move the image to the left hand side of the screen.
That will result in video lines that start with multiple pixels that
have the same value as the Video Guard Band that precedes them.
Receivers that will just keep skipping Video Guard Band values will
now fail and either loose sync or these video lines will shift.

Hantro video decoder driver
===========================
The Hantro video decoder driver implements the following driver-specific controls:
``V4L2_CID_HANTRO_HEVC_SLICE_HEADER_SKIP (integer)``
Specifies to Hantro HEVC video decoder driver the number of data (in bits) to
skip in the slice segment header.
If non-IDR, the bits to be skipped go from syntax element "pic_output_flag"
to before syntax element "slice_temporal_mvp_enabled_flag".
If IDR, the skipped bits are just "pic_output_flag"
(separate_colour_plane_flag is not supported).
.. note::
This control is not yet part of the public kernel API and
it is expected to change.

according to :ref:`hevc` 7.3.1.1 General NAL unit syntax, hence
contains emulation prevention bytes when required.

``V4L2_CID_MPEG_VIDEO_BASELAYER_PRIORITY_ID (integer)``
Specifies a priority identifier for the NAL unit, which will be applied to
the base layer. By default this value is set to 0 for the base layer,
and the next layer will have the priority ID assigned as 1, 2, 3 and so on.
The video encoder can't decide the priority id to be applied to a layer,
so this has to come from client.
This is applicable to H264 and valid Range is from 0 to 63.

This is applicable to the H264 and HEVC encoders.
``V4L2_CID_MPEG_VIDEO_FRAME_LTR_INDEX (integer)``
After setting this control the frame that will be queued next
will be marked as a Long Term Reference (LTR) frame
and given this LTR index which ranges from 0 to LTR_COUNT-1.
This is applicable to the H264 and HEVC encoders.
Source Rec. ITU-T H.264 (06/2019); Table 7.9
``V4L2_CID_MPEG_VIDEO_USE_LTR_FRAMES (bitmask)``
Specifies the Long Term Reference (LTR) frame(s) to be used for

This provides a bitmask which consists of bits [0, LTR_COUNT-1].
This is applicable to the H264 and HEVC encoders.
``V4L2_CID_STATELESS_HEVC_DECODE_PARAMS (struct)``
Specifies various decode parameters, especially the references picture order
count (POC) for all the lists (short, long, before, current, after) and the

to the driver without any start code. The bitstream data should be
according to :ref:`hevc` 7.3.1.1 General NAL unit syntax, hence
contains emulation prevention bytes when required.
* - ``V4L2_MPEG_VIDEO_HEVC_START_CODE_ANNEX_B``

valid start codes can be 3-bytes 0x000001 or 4-bytes 0x00000001.
``V4L2_CID_MPEG_VIDEO_BASELAYER_PRIORITY_ID (integer)``
Specifies a priority identifier for the NAL unit, which will be applied to
the base layer. By default this value is set to 0 for the base layer,
and the next layer will have the priority ID assigned as 1, 2, 3 and so on.
The video encoder can't decide the priority id to be applied to a layer,
so this has to come from client.
This is applicable to H264 and valid Range is from 0 to 63.

given time that the encoder can keep.
This is applicable to the H264 and HEVC encoders.
``V4L2_CID_MPEG_VIDEO_FRAME_LTR_INDEX (integer)``
After setting this control the frame that will be queued next
will be marked as a Long Term Reference (LTR) frame
and given this LTR index which ranges from 0 to LTR_COUNT-1.
This is applicable to the H264 and HEVC encoders.

This provides a bitmask which consists of bits [0, LTR_COUNT-1].
This is applicable to the H264 and HEVC encoders.

``V4L2_CTRL_FLAG_GRABBED`` flag when buffers are allocated or
streaming is in progress since most drivers do not support changing
the format in that case.
* - ``V4L2_CTRL_FLAG_DYNAMIC_ARRAY``
- 0x0800
- This control is a dynamically sized 1-dimensional array. It
behaves the same as a regular array, except that the number
of elements as reported by the ``elems`` field is between 1 and
``dims[0]``. So setting the control with a differently sized
array will change the ``elems`` field when the control is
queried afterwards.
