Mainly this fixes handling special values of -enc_time_base ('demux' or
'filter') for audio. It also prints a warning if -enc_time_base is
specified for subtitles, instead of ignoring it silently (current
subtitle encoding API only works with AV_TIME_BASE_Q).
This function converts packet timestamps from the input stream timebase
to OutputStream.mux_timebase, which may or may not be equal to the
actual output AVStream timebase (and even when it is, this may not
always be the optimal choice due to bitstream filtering).
Just keep the timestamps in input stream timebase, they will be rescaled
as needed before bitstream filtering and/or sending the packet to the
muxer.
Move the av_rescale_delta() call for audio (needed to preserve accuracy
with coarse demuxer timebases) to write_packet.
Drop now-unused OutputStream.mux_timebase.
Bitstream filtering input timebase is not always necessarily equal to
OutputStream.mux_timebase. Also, set AVPacket.time_base correctly for
packets output by bitstream filters
Do not rescale at all in of_output_packet() when not doing bitstream
filtering, as it's unnecessary - write_packet() will rescale to the
actual muxer timebase.
When the marker writing code was merged from libav to FFmpeg
in dc62016c, it failed to take into account that the meaning of
cluster_pos had changed in bda5b662; in particular, the special
value for “I'm not currently working on a cluster” had changed
from 0 to -1. This makes the avio_write_marker() call never
be called. Update the if statement to fix it.

The loader ensures only that functions with tagged supported extensions
exist, rather than ensuring only those with supported extensions are
loaded.
As the init function uses Vulkan functions, whose loading requires them
to have the extension flags set, the extension flags are guaranteed
to also exist at this point.
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.
This new upstream struct simplifies params struct management by allowing
them to all be contained in a single dynamically allocated struct. This
commit switches to the new API in a backwards-compatible way.
The only nontrivial change that was required was to handle
`sigmoid_params` in a way consistent with the rest of the params
structs, instead of setting it directly to the upstream default.
This prevents code duplication in the source form by calling the parse
code that was moved to avcodec last commit. The code will be duplicated
in binary form for shared builds (it's not that large), but for source
code it will only exist in one location now.

Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the
end of the stream in order to packetize the codec, and it looks at
the headers to set preliminary information like dimensions and pixel
format.
Note that much of this code is duplicated from avformat/jpegxl_probe.c,
but that code will be removed and call this instead in the next commit.

Before this commit, the decoder erroneously assumes that the AVFrame
passed to the receive_frame is the same one each time. Now it keeps an
internal AVFrame to write into, and copies it over when it's done.

OpenVINO API 2.0 was released in March 2022, which introduced new
features.
This commit implements current OpenVINO features with new 2.0 APIs. And
will add other features in API 2.0.
Please add installation path, which include openvino.pc, to
PKG_CONFIG_PATH mannually for new OpenVINO libs config.
