No deprecation guards, because the old decode API (for which this field
is needed) doesn't have any either.
This field should be removed together with the old decode calls.

Return a channel layout and the number of channels based on the specified name.
This function is similar to av_get_channel_layout(), but can also parse unknown
channel layout specifications.
Unknown channel layout specifications are a decimal number and a capital 'C'
suffix, in order to not break compatibility with the lowercase 'c' suffix,
which is used for a guessed channel layout with the specified number of
channels.

This commit adds the avio_get_dyn_buf function which allows accessing
the
content of a DynBuffer without destroying it.
This is required in matroskaenc for preliminary writing (correct) mkv
headers.
Context for this change is fixing regression bug #5977.

While no decoder currently exports spherical information, this type
represents a frame property that has to be passed through from container
to frames.

Functionally similar to av_packet_add_side_data(). Allows the use of an
already allocated buffer as stream side data.

The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.
(cherry picked from commit 2124711b95)
The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device. If this
behaviour is unwanted, the user can also set the quirks field
manually.
Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.
(cherry picked from commit 4926fa9a4a)
Adds the new av_hwframe_map() function, which allows mapping between
hardware frames and normal memory, along with internal support for
implementing it.
Also adds av_hwframe_ctx_create_derived(), for creating a hardware
frames context associated with one device using frames mapped from
another by some hardware-specific means.
This allows a consumer to run the muxer's init function without actually
writing the header, which is useful in chained muxers that support
automatic bitstream filtering.
This will be used to allow writing file sequences using the tee output onto
multiple places in parallel

P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two
bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs.
