Adds missing ifdef guards to function prototypes depending on definitions from
dxva.h which are not available in Mingw-w64 version 4.0. The configure script
already checks for HEVC/VP9 types in dxva.h.

Use AV1DecContext's current_obu to access the original OBUs, and
feed them to videotoolbox, rather than the bare slice data passed
via decode_slice.
This requires a small addition to AV1DecContext, for keeping track
of the current range of OBUs that belong to the current frame.

We always write minimal slices, the size calculation is wrong in some
corner cases but as its always 1x1 (minus1) we can for now just hard-code it
This helps with ticket 5548

Add a mechanism to AVClass to allow objects to signal their state to
generic code. When an object flags itself with the 'initialized' state,
print an error (and fail, after the next major bump) if the caller
attempts to set non-runtime options.
The options-setting functions share several operations at their
beginnings - locating the option and the object to operate on, handling
the read-only and deprecated flags, and constructing the pointer to the
target value. Some of the functions also do not perform some of the
checks, although they should. E.g. a deprecation warning is currently
only printed for av_opt_set().
Introduce a prologue function that is called from every av_opt_set*()
and performs all these common initialization operations.
Based on a patch by Hacene Bouaroua.
Fixes ticket #11171.

Will be used to export certain information present in HEIF samples, like
rotation metadata, ICC profiles, and potentially others.

Otherwise, things like ICC profiles as read from the colr box meant for an item
with no stream (like a grid) may end up being added to the wrong stream.

The EXT-X-DISCONTINUITY tag was not being added to subtitle streams,
causing synchronization issues.i
This patch ensures that the tag is applied consistently across video and subtitle streams.

To streamcopy_init().
This will allow to simplify the control flow in ost_add() by moving the
ost_get_filters() call (which previously had to handle both encoding and
streamcopy streams) to ost_bind_filter() (which is only called for
audio/video encoding).
Also, return EINVAL rather than ENOSYS, as trying to combine filtering
with streamcopy is a parameter error.
Similar to what was previously done for other components, e.g. decoders
(see 3b84140a1b).
Start by moving {samples,frames}_encoded into the public struct.
"int-list" options are a hack that provides rudimentary support for
array-type options by treating them as byte arrays (i.e.
AV_OPT_TYPE_BINARY). Since we now have proper array-type options, they
should replace "int-list" everywhere (which happens to be just
buffersink).
I plan to look after and test them for the forseeable future.
I am not a committer but do care for these muxers/demuxers.
