media: Add AV1 uAPI
This patch adds the AOMedia Video 1 (AV1) kernel uAPI. This design is based on currently available AV1 API implementations and aims to support the development of AV1 stateless video codecs on Linux.

This format is adapted for stateless video decoders that implement a AV1

pipeline with the :ref:`stateless_decoder`. Metadata associated with the
|

frame to decode is required to be passed through the

``V4L2_CID_STATELESS_AV1_SEQUENCE``, ``V4L2_CID_STATELESS_AV1_FRAME``,
|

and ``V4L2_CID_STATELESS_AV1_TILE_GROUP_ENTRY`` controls.
|

See the :ref:`associated Codec Control IDs <v4l2-codec-stateless-av1>`.
|
||||
Exactly one output and one capture buffer must be provided for use with
|
||||
this pixel format. The output buffer must contain the appropriate number
|

of macroblocks to decode a full corresponding frame to the matching

capture buffer.

* @reference_frame_ts: the V4L2 timestamp of the reference frame slots.
|
||||
* @ref_frame_idx: used to index into @reference_frame_ts when decoding
|

|
||||
* The timestamp refers to the timestamp field in struct v4l2_buffer. Use
|
||||
* v4l2_timeval_to_ns() to convert the struct timeval to a __u64.
|
||||
* @refresh_frame_flags: contains a bitmask that specifies which reference frame
|
