ec2036454b avformat: add a disposition field to AVStreamGroup
The existing (and upcoming) available group types are meant to combine several
streams for presentation, with the result being treated as if it was a stream
itself.
For example, a file could export two stream groups of the same type with one of
them as the "default".

5e751dabc5 doc/APIchanges: document newly added buffersrc field
This was accidentally removed in a prior revision of the series,
alongside the corresponding (separate) version bump. Instead coalesce it
into the follow-up commit's entry, since that's the lowest version
actually supporting the new fields.

8c7934f73a avfilter: add negotiation API for color space/range
Motivated by YUVJ removal. This change will allow full negotiation
between color ranges and matrices as needed. By default, all ranges and
matrices are marked as supported.

Because grayscale formats are currently handled very inconsistently (and
in particular, assumed as forced full-range by swscale), we exclude them
from negotiation altogether for the time being, to get this API merged.

After filter negotiation is available, we can relax the
grayscale-is-forced-jpeg restriction again, when it will be more
feasible to do so without breaking a million test cases.

Note that this commit updates one FATE test as a consequence of the
sanity fallback for non-YUV formats. In particular, the test case now
writes rgb24(pc, gbr/unspecified/unspecified) to the matroska file,
instead of rgb24(unspecified/unspecified/unspecified) as before.

57c16323f2 avutil/pixdesc: add AV_PIX_FMT_FLAG_XYZ
There are already several places in the codebase that match desc->name

I have no idea why this is not just a flag.

Motivated by my desire to add yet another check for XYZ to the codebase,

5432d2aaca avformat/avformat: use the side data from AVStream.codecpar
Deprecate AVStream.side_data and its helpers in favor of the AVStream's
codecpar.coded_side_data.

This will considerably simplify the propagation of global side data to decoders
and from encoders. Instead of having to do it inside packets, it will be
available during init().
Global and frame specific side data will therefore be distinct.

dd48e49d54 avformat/avformat: Deprecate AVFMT_ALLOW_FLUSH
It is of no value to the user, because every muxer can always
be flushed with a NULL packet. As its documentation shows
("If not set, the muxer will not receive a NULL packet in
the write_packet function") it is actually an internal flag
that has been publically exposed because there was no internal
flags field for output formats for a long time. But now there is
and so use it by replacing the public flag with a private one.

ba9cd06c76 avutil/avutil: make AV_TIME_BASE_Q available in C++
ISO C++ forbids compound-literals. It's not available with MSVC.
This is a known issue from 10 years ago, and that's why there is a
av_get_time_base_q().

Since we have no plan to remove AV_TIME_BASE_Q, just make it
available in C++.

There are multiple choices:
1. Use C++11 syntax: AVRational{1, AV_TIME_BASE}

Users may still use C++98 to write new code. So no.

2. Use av_get_time_base_q().

It's for this purpose. But it's not compile time constants as
AV_TIME_BASE_Q in C.

So I choose av_make_q() as Anton's suggestion.

85e075587d lavf: deprecate AVFMT_FLAG_SHORTEST
It was added in cb114ed464 with the comment
"This will allow fixing several bugs with the -shortest option".

Since
* there is no explanation of what these bugs are
* libavformat is not the place to work around ffmpeg CLI bugs
* there is no indication that this feature is actually in use
deprecate it without replacement.

423b6a7e49 avutil/imgutils: Add wrapper for av_image_copy() to avoid casts
av_image_copy() accepts const uint8_t* const * as source;
lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.

This commit changes this by adding a static inline wrapper
for av_image_copy() that casts between the two types
so that we do not need to add casts everywhere else.
