These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This reverts commit eb88ccb92e.
AVCodecContext fields are the proper place for a decoder to export such values.
This change is in preparation for the following commits.
add option named rtmp_enhanced_codec,
it would support hvc1,av01,vp09 now,
the fourcc is using Array of strings.

These are in-place transforms, required for DCT-I and DST-I.
Templated as the mod2 variant requires minor modifications, and is
required specifically for DCT-I/DST-I.
Can be used to configure libplacebo's underlying raw options, which
sometimes includes new or advanced / in-depth settings not (yet) exposed
by vf_libplacebo.
C++ doesn't support designated initializers until C++20. We have
a bunch of pre-defined channel layouts, the gains to make them
usable in C++ exceed the losses.
Bump minor version so C++ project can check before use these defines.
Also initialize .opaque field explicitly to reduce warning in C++.

The commits eac4324bfb and
cd8211527e renamed the examples, but the
targets were not updated. Hence, the builds are missing -lm.

Stop claiming the argument is always a floating point number, which
* confuses floating point and decimal numbers
* is not always true even accounting for the above point
Read the timebase from FrameData rather than the input stream. This
should fix#10393 and generally be more reliable.
Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.
This decoding flag makes decoders drop all frames after a parameter
change, but what exactly constitutes a parameter change is not well
defined and will typically depend on the exact use case.
This functionality then does not belong in libavcodec, but rather in
user code
Useful for discovering bugs that depend on a specific thread count.
Use like THREADS=randomX for a random thread count from 1 to X, with
X=16 when not specified. Note that the thread count is different for
every test.
Uses the existing code for av_get_random_seed() to return a buffer with
cryptographically secure random data, or an error if none could be generated.

Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output. We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.
Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets. This is
because subsequent patches will introduce support for other
data codecs.
