Andreas Cadhalpun fdc94db37e sbr_qmf_analysis: sanitize input for 32-bit imdct 
If the input contains too many too large values, the imdct can overflow.
Even if it didn't, the output would be larger than the valid range of 29
bits.

Note that this is a very delicate limit: Allowing values up to 1<<25
does not prevent input larger than 1<<29 from arriving at
sbr_sum_square, while limiting values to 1<<23 breaks the
fate-aac-fixed-al_sbr_hq_cm_48_5.1 test.

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 a mean to alter decoded Audio and Video through chain of 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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
