e02a3b40a5 avutil/pixfmt: add XV48 pixel format
Much like XV30 and XV36 in d75c4693fef51e8f0a1b88798530f4c5147ea906,
XV48 is added to support 16bit 4:4:4 as defined by Microsoft.

-disposition:
Clarify the meaning of the default value, and how the '+' and '-'
prefixes work. Add more examples.

-stats:
Clarify that it appears as an "info"-level log.

-progress:
Add info about the "progress" key's value being "continue" or "end".
Add an example of logging to stdout.

5e50a56b9c swscale: add new frame testing API
Replacing the old sws_isSupported* API with a more consistent family
of functions that follows the same signature and naming convention,
including a placeholder for testing the color space parameters that
we don't currently implement conversions for.

These functions also perform some extra basic sanity checking.

configure: drop yasm support
We started defauling to nasm 8 years ago.
We are still compatible with yasm 0.8.0, released in 2009. **15 years ago**.
The time has more than come to remove support for it.

Maintaining compatibility started cutting into writing new code long ago.
We still can't have 2-argument instructions, preprocessor booleans, and all
AVX2 code must still be wrapped in ifdefs. Newly added code often breaks this.

0548ab2e42 lavu/log,opt: detect setting non-runtime options post-init
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.

1efcdbc54d lavfi/buffersink: add array-type options to replace "int-list" ones
"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).

da420ac6e1 fftools/ffmpeg: add support for multiview video
This extends the syntax for specifying input streams in -map and complex
filtergraph labels, to allow selecting a view by view ID, index, or
position. The corresponding decoder is then set up to decode the
appropriate view and send frames for that view to the correct
filtergraph input(s).

9bcb86b0fa avdevice/decklink_dec: extend available actions on signal loss
Deprecate the option 'draw_bars' in favor of the new option 'signal_loss_action',
which controls the behavior when the input signal is not available
(including the behavior previously available through draw_bars).
The default behavior remains unchanged to be backwards compatible.
The new option is more flexible for extending now and in the future.

The new value 'repeat' repeats the last video frame.
This is useful for very short dropouts and was not available before.

3305767560 avcodec: add avcodec_get_supported_config()
This replaces the myriad of existing lists in AVCodec by a unified API
call, allowing us to (ultimately) trim down the sizeof(AVCodec) quite
substantially, while also making this more trivially extensible.

In addition to the already covered lists, add two new entries for color
space and color range, mirroring the newly added negotiable fields in
libavfilter.

Once the deprecation period passes for the existing public fields, the
rough plan is to move the commonly used fields (such as
pix_fmt/sample_fmt) into FFCodec, possibly as a union of audio and video
configuration types, and then implement the rarely used fields with
custom callbacks.
