Manuel Lauss d21134313f avformat/smush: read ANIMv2 a/v parameters 
SMUSH ANIM files with subversion 2 provide additional fields for
framerate and samplerate, use them if available, otherwise
default to 12 fps which is the default for almost all ANIMv2
since 1995.

Fixes the too-fast playback of test files from LucasArts games
released 1995-1997.  It was not noticed since Audio for
those isn't decoded by ffmpeg.

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.
