avcodec/libjxl.h: include version.h 
This file has been exported since our minimum required version (0.7.0),
but it wasn't documented. Instead it was transitively included by
<jxl/decode.h> (but not jxl/encode.h), which ffmpeg relied on.

libjxl broke its API in libjxl/libjxl@66b9592393 by removing
the transitive include of version.h, and they do not plan on adding
it back. Instead they are choosing to leave the API backwards-
incompatible with downstream callers written for some fairly recent
versions of their API.

As a result, we include <jxl/version.h> to continue to build against
more recent versions of libjxl. The version macros removed are also
present in that file, so we no longer need to redefine them.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
