Discussion page regarding the rework of the ffmpeg audio api to acomodate the requirements needed for todays audio codecs.

Features needed

  • Generalized downmixing (simd optimized)
  • Output channel request function (ie, request a specified number of channels, default should be >2 mapped to 2 channels)
  • Optimized interleaving
  • Allow planer output, (don't duplicate interleaving code in every codec)
  • Add support for other bitdepths then 16bits
  • Add a better fft routine, maybe the KISS one
