  opusenc : implement a psychoacoustic system
  This commit implements a psychoacoustic system for the native Opus
  
  encoder. Its unlike any other psychoacoustic system known since its
  
  capable of using a lookahead to make better choices on how to treat the
  
  current frame and how many bits to allocate for it (and future frames).
  Also, whilst the main bulk of the analysis function has to run in a
  
  single thread, the per-frame anaylsis functions does not modify the main
  
  psychoacoustic context, so in the future it will be fairly trivial to
  
  run those as slice threads.

• build system : fix dependency generation

  8 octobre 2015, par Christophe Gisquet

  build system : fix dependency generation
  When trying to build the binary dct-test under MSYS2/Win64, the
  
  makefile rule does not have the SUBDIR in the target for its
  
  object file.
  Consequently, modifications to various include files (e.g. C ones)
  
  do not trigger a recompilation.
  When tracing the dependency generating, the dependency generation
  
  has this strange content (linebreak inserted) :
  
  sed -e "/^#.*/d" -e "s,^ []*dct\.o,libavcodec/dct.o," \
  
   > libavcodec/dct-test.d
  For some reason, the $(*F) has weird content. It looks simpler to
  
  use $(@F) instead of $(*F)\.o, although this was tested on one
  
  single version of make.
