[FFmpeg-devel] [PATCH 0/9] v2: simple_idct for 10/12 bits and DNxHD

[Christophe Gisquet]

Summary of changes since last version:
- implemented pure idcts, needed for vf_spp
- consequently, modified dct-test as the wrapper is no longer needed
- fixed overflow in 12bits version by disabling a trick
- freed a xmm reg for prores, and used it for the rounder in simple_idct

Christophe Gisquet (9):
  dnxhdenc: fix scan used for bitstream generation
  x86: prores: templatize 10 bits simple_idct
  x86: simple_idct_put: 10bits versions
  x86: proresdsp: simple_idct: free or use 1 xmm reg
  x86: simple_idct: add pure idct functions
  x86: simple_idct: 12bits versions
  dct-test: add infrastructure for 10 bits
  x86: dct-test: add 10 bits versions.
  x86: dct-test: add 12 bits versions
