[FFmpeg-devel] [PATCH 0/9] x86 DSP code for AAC SBR.

[Christophe Gisquet]

Those patches are also being reviewed by libav developpers, but more input is
welcome. Patch 9/9 is a WIP that will probably go nowhere and is therefore
omitted.

Patch 8 could be controversial, but there is a lot of code already assuming
IEEE754 floats.

Christophe Gisquet (9):
  SBR DSP x86: implement SSE qmf_pre_shuffle
  SBR DSP x86: implement SSE qmf_deint_neg
  SBR DSP x86: implement SSE qmf_deint_bfly
  x264asm: fix cmp* number of arguments
  SBR DSP x86: implement SSE hf_apply_noise
  sbrdsp: unroll sbr_autocorrelate_c
  sbrdsp: unroll and use integer operations
  x86: sbrdsp: implement SSE neg_odd_64
