x11grab can capture windows by their ID, but gdigrab can only capture
windows by their names, internally calling FindWindowW to lookup its
handle.
This patch simply allows the user to specify a window handle directly.

Change the main loop and every component (demuxers, decoders, filters,
encoders, muxers) to use the previously added transcode scheduler. Every
instance of every such component was already running in a separate
thread, but now they can actually run in parallel.
Changes the results of ffmpeg-fix_sub_duration_heartbeat - tested by
JEEB to be more correct and deterministic.
Partially fixes ticket #798

Fix rendering of int values within a side data element, which was
broken since commit d2d3a83ad9, where the side data element was
correctly marked as a variable fields element. Logic to render a
string variable was implemented already, but it was not implemented
for the int fields path, which was enabled by that commit.
Also, code and schema is changed in order to account for multiple
variable-fields elements - such as side data, contained within the
same parent. Previously it was assumed that a single variable-fields
element was contained within the parent, which was the case for tags,
but is not the case for side-data.
Previously data was rendered as:
<side_data_list>
<side_data side_data_type="CPB properties" max_bitrate="0" min_bitrate="0" avg_bitrate="0" buffer_size="327680" vbv_delay="-1"/>
</side_data_list>
Now as:
<side_data_list>
<side_data type="CPB properties">
<side_datum key="side_data_type" value="CPB properties"/>
<side_datum key="max_bitrate" value="0"/>
<side_datum key="min_bitrate" value="0"/>
<side_datum key="avg_bitrate" value="0"/>
<side_datum key="buffer_size" value="49152"/>
<side_datum key="vbv_delay" value="-1"/>
</side_data>
</side_data_list>
Variable-fields elements are rendered as a containing element wrapping
generic key/values elements, enabling use of strict XML schema.

It is badly named (should have been -top_field_first, or at least -tff),
underdocumented and underspecified, and (most importantly) entirely
redundant with the setfield filter.
Add demuxer to probe raw vvc and parse vvcc byte stream format.

I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
This patch add another ARIB caption decoder using libaribcaption
external library.
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ass as same as libaribb24.
Advantages compared with libaribb24 on ASS subtitle are:
* Subtitle positioning.
* Multi-rect subtitle: some captions are displayed at different
position at a time.
* More stability and reproducibility.
To compile with this feature:
* libaribcaption external library has to be pre-installed.
https://github.com/xqq/libaribcaption
* configure with `--enable-libaribcaption` option.
`--enable-libaribb24` and `--enable-libaribcaption` options are
not exclusive. If both enabled, libaribcaption precedes as
order listed in `libavcodec/allcodecs.c`.
