avformat/jpegxl_anim_dec: add animated JPEG XL demuxer
Animated JPEG XL files requires a separate demuxer than image2, because
the timebase information is set by the demuxer. Should the timebase of
an animated JPEG XL file be incompatible with the timebase set by the
image2pipe demuxer (usually 1/25 unless set otherwise), rescaling will
fail. Adding a separate demuxer for animated JPEG XL files allows the
timebase to be set correctly.

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

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples
