All subtargets which should run the fate-filter-pixdesc% need to
generate and include tests/pixfmts.mak. Most noteable missing target was
fate itself.

Every supported format is converted to RGB.

Add CPU count and number threads as informative values for fate.

libavutil/cpu-test prints raw and effective cpu flags to STDERR. Detected
cpu flags can be useful for debugging fate errors.

No comparison of the result against a expected result since that would
require fate config specific references.

This allows running all the tests individually and/or in parallel.

- all of them testing HEVC version 1

This fixes running fate in configs where the samples are located
in a different path on the target.

Partially fixes Ticket #3404 (xbr filter remaining)

It has not been properly maintained for years and there is little hope
of that changing in the future.
It appears simpler to write a new replacement from scratch than
unbreaking it.

It was previously untested.

This only checks that things havnt changed, the values provide little
help in determining if a change is good or bad.

Improvements welcome!

The official samples are 50% smaller
Avoid having reference samples which are strongly linked to the used resampler
implementation. (which for example would require new samples to be used if this
implementation changes)
Also its more correct to use the official samples instead of the current
decoder output

also enable tests
The tests also fully pass as well with the previous samples.

Based off the srt encoder. The following features are unimplemented:

- fonts, colors, sizes
- alignment and positioning

The rest works well. For example, use ffmpeg to convert subtitles into the .vtt format:

  ffmpeg -i input.srt output.vtt

This seems to be needed on some 32bit arches.

Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

Initial implementation by Andrew D'Addesio <modchipv12@gmail.com> during
GSoC 2012.

Completion by Anton Khirnov <anton@khirnov.net>, sponsored by the
