James Almer c92c6cbf19 avcodec/aacenc: fix PCE configs for known native layouts 
Many of the entries were downright wrong, like mistagging LFE elements as
SCE, as well as trying to match the native channel ordering in the PCE
by placing CPE elements before SCE ones in some cases (like with FRONT
elements), which is not spec compliant and results in unparseable streams.

Remove the three layouts that define top channels. It's not clear how they
should be signaled in PCE.

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.
