Move header_written into it, which is not (and should not be) used by
any code outside of ffmpeg_mux.
In the future this context will contain more muxer-private state that
should not be visible to other code.
The amount of padding samples reported by containers take into account the
extended samplerate in HE-AAC.
Fixes ticket #9671.

This issue would cause segmetaion fault when running srcnn model with
sr filter by TensorFlow backend. This filter would free the frame incorectly.

Using parameter from AVCodecContext to reset qsv codec is more suitable
for MFXVideoENCODE_Reset()'s usage. Per-frame metadata is more suitable
for the usage of mfxEncodeCtrl being passed to
MFXVideoENCODE_EncodeFrameAsync(). Now change it to use the value
from AVCodecContext.
Because q->param is passed to both "in" and "out" parameters when call
MFXVideoENCODE_Query(), the value in q->param may be changed. New
variables are added to store old configuration, so that we can detect
real parameter change.

Dividing one line log into several av_log() call is not thread safe. Now
merge these strings into one av_log() call.

The only duration field currently present in AVFrame is pkt_duration,
which is semantically restricted to those frames that are output by
decoders.
Add a new field that stores the frame's duration without regard for how
that frame was produced. Deprecate pkt_duration.
It need not be writable; in fact, it is often not writable even if
the packet sent to the decoder was writable, because the generic code
calls av_packet_ref() on it. It is never writable if a user
drains the decoder after every packet, because in this case the decode
callback is called from avcodec_send_packet().

wrapped_avframe_decode() uses an AVFrame as dst in av_frame_move_ref()
after having called ff_decode_frame_props() to attach side-date
to this very frame. This leaks all the side-data and metadata
that ff_decode_frame_props() has attached.
This happens in various fate-filter-metadata tests since
6ca43a9675.
These particular leaks (which affect metadata-only)
could be fixed by not adding metadata side-data to AVPackets
in libavdevice if they are also available from the AVFrames.
Yet this would break users that extract the metadata from
AVPackets.
The changes to FATE happen because of the way av_dict_set()
works when it overwrites an already existing entry:
It overwrites the entry to be overwritten with the last entry
and adds the new entry at the end. The end result is that
the first entry of the dict is the second-to-last-entry of
the original dict, the last entry of the dict is the last
entry of the old dict and the first count - 2 entries
of the original dict are at positions 1..count - 2 in their
original order.

and remove FF_CODEC_CAP_INIT_THREADSAFE
All our native codecs are already init-threadsafe
(only wrappers for external libraries and hwaccels
are typically not marked as init-threadsafe yet),
so it is only natural for this to also be the default state.

Streams with all zero sample_delta in 'stts' have all zero dts.
They have higher chance be chose by mov_find_next_sample(), which
leads to seek again and again.
For example, GoPro created a 'GoPro SOS' stream:
Stream #0:4[0x5](eng): Data: none (fdsc / 0x63736466), 13 kb/s (default)
Metadata:
creation_time : 2022-06-21T08:49:19.000000Z
handler_name : GoPro SOS
With 'ffprobe -show_frames http://example.com/gopro.mp4', ffprobe
blocks until all samples in 'GoPro SOS' stream are consumed first.

This avoids an extra copy of potentially quite big video frames.
Instead of copying the entire frames data into a rawvideo packet it
packs the frame into a wrapped avframe packet and passes it through
as-is.
Unfortunately, wrapped avframes are set up to be video frames, so the
audio frames continue to be copied.
Additionally, this enabled passing through video frames that previously
were impossible to process, like hardware frames or other special
formats that couldn't be packed into a rawvideo packet.
