[FFmpeg-devel] [PATCH 0/3] floating-point AC-3 encoder

[Justin Ruggles]

Here is my 2nd attempt at adding a floating-point AC-3 encoder.
This time I modelled it on the mp3 decoder per Michael's suggestion.

I made the new floating-point decoder the default and kept the name
ac3_encoder for that one.  I renamed the current encoder
ac3_fixed_encoder.

Justin Ruggles (3):
  Move fixed-point parts of the AC-3 encoder to separate files.
  Add floating-point AC-3 encoder.     Rename the fixed-point AC-3
    encoder ac3_fixed_encoder.     Rename test acodec-ac3 to
    acodec-ac3_fixed and update dependencies.     Modify test lavf-rm
    to use -acodec ac3_fixed.
  Use DSPContext.vector_fmul() and DSPContext.vector_fmul_reverse() in 
       floating-point version of apply_window().     46% faster in
    function apply_window().
