[FFmpeg-devel] [PATCH 0/6] wmalossless: fix 16bits speed regression

[Christophe Gisquet]

I think only the 2 first patches are needed, but I prefer the code
from the 3rd+4th patches. Overall, it's still not the nicest code, and
valgrind-proofing the patchset is needed (not possible atm for me).

The SSE4 implementation is not worthwhile in my opinion.

Christophe Gisquet (6):
  fate: wma: add lossless 24bits test
  wmalossless: allow calling madd_int16
  wmalossless pro: move lms_update
  wmalossless: template code to remove inloop if
  x86: lossless audio: SSE4 madd 32bits
  lossless audio dsp: unroll
