Rostislav Pehlivanov c92cc2d559 aacenc: add a faster version of twoloop as the "fast" coder
Does nothing fancy but still sounds very decent at 128kbps.
Still room to improve by bringing in the low pass and PNS management
from the main big twoloop which should improve its quality but not
sacrifice that much speed.

  • 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.
