We don't need to print the tags here because they're added as dict
elements to AVFrame->metadata and are printed elsewhere with ffprobe
-show_frames.

opt_codec() is mostly copied over from ffplay.c.
This is useful when different decoders have different capabilities,
or to test a specific decoder.

This allows future addition of options without
changes to the signature of avtext_context_open().

An identical call exists in ffmpeg.c
With POSIX/glibc, stderr is already unbuffered (or line-buffered when
a terminal is connected), but not in case of MSVCRT.
Explicitly calling setvbuf() like in this commit, makes the Windows
runtime behave like POSIX, giving the same “print immediately” behavior.

avtextwriter_create_file() creates an AVIOContext whose pointer
resides in its private context. If it were not always closed on
uninit, the AVIOContext would leak, so it makes no sense
to have this parameter.

It can't really happen, because no currently used pixel format
has a name exceeding the size of the buffer.

It is currently not due to endianness. This forced to add
workarounds with sed in fate/mxf.mak (which are removed
in this commit).
This is supposed to fix the enhanced-flv-hevc-hdr10 test
on big endian systems.

This removes several #if checks. While just at it, also switch
to static mutex initialization.
This commit does not enable -show_log for builds without threads
though.

Currently, ffprobe has two stream-level fields that do not work,
closed_captions and film_grain).
Their value is always 0 because ffprobe cannot access the internal
codec properties when it is setting up its stream contexts.
In this commit, add the new option -analyze_frames to ffprobe,
allowing the user to read frames up to the interval they have defined
and fill these fields based on what is exposed in AVPacketSideData.
Additionally, in the same commit, don't write these fields to
the output unless analyze_frames is enabled. Finally, fix the
FATE test refs accordingly and update the docs.

Share the code between encoding and decoding. Instead of checking every
stream's options dictionary (which is also used for other purposes),
track all used options in a dedicated dictionary.
This avoids hardcoding any implementation-specific limitiations as
part of the API, and allows for future expandability.
This also allows API users to more conveniently convert the
values into floats without hardcoding specific conversion constants.
The API was committed a few days ago, so changing this field now
is within the realms of acceptable.
ffprobe is meant to generate parseable output, and if a field is present, it
should be printed even if it has a default value.

Both the codecpar's width and height, and the SAR num and den are
ints, which can overflow. Cast to int64_t, which is what av_reduce
takes.
Without this, occasionally, display_aspect_ratio can be negative in
ffprobe's -show_stream output.

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Components and pieces are side data specific fields and there's a variable
amount of them.
They also need to be identified in some form, so print a type too.
