Marth64 90af8e07b0 fftools/ffprobe: add analyze_frames option for CC and grain detection
Currently, ffprobe has two stream-level fields that do not work,
closed_captions and film_grain).

Their value is always 0 because ffprobe cannot access the internal
codec properties when it is setting up its stream contexts.

In this commit, add the new option -analyze_frames to ffprobe,
allowing the user to read frames up to the interval they have defined
and fill these fields based on what is exposed in AVPacketSideData.

Additionally, in the same commit, don't write these fields to
the output unless analyze_frames is enabled. Finally, fix the
FATE test refs accordingly and update the docs.

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.
