And av_stream_get_codec_timebase().
They were both added for ffmpeg CLI, which no longer calls either of
them. Furthermore the notion of "internal stream timing info" that needs
to be transferred with a special magic API function is fundamentally
flawed and should be removed.
This lets us detect when a container has flagged a stream as multilayer.

This allows ending up with a normal, non-fragmented file when
the file is finished, while keeping the file readable if writing
is aborted abruptly at any point. (Normally when writing a
mov/mp4 file, the unfinished file is completely useless unless it
is finished properly.)
This results in a file where the mdat atom contains (and hides)
all the moof atoms that were part of the fragmented file structure
initially.

Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configure step.

It's a common usecase to request a video size after crop. Before
this patch, user must know the video size before crop, then set
crop_right/crop_bottom accordingly. Since HEVC can have different
CTU size, it's not easy to get/deduce the video size before crop.
With the new width/height options, there is no such requirement.

Codec IDs have split from `avcodec.h` into `codec_id.h` after commit
c6978418b8.
General documentation contents (which are now in
`general_contents.texi`) have split from the header in `general.texi`
after commit 6accb7718a.
Update the developer documentation to match these changes.

This is automatically enabled if the width/height expressions reference
any ref_* variable. This will ultimately serve as a more principled
replacement for the fundamentally broken scale2ref.

429 and 503 codes can, and often do (e.g. all Google Cloud
Storage URLs can), return a Retry-After header with the error,
indicating how long to wait, asd either a date, or in seconds,
before retrying again. If it is not respected by, for example,
using our default backoff stratetgy instead, chances of success
are very unlikely.
Some references:

This adds an AVOption to respect that header.
