[FFmpeg-devel] [PATCH 0/9] v4: simple_idct for 10/12 bits and DNxHD

[Christophe Gisquet]

Changes since v3:
- proper fix (famous last words) for issues in encoder
- fate test that showed an overflow
- fix to previous code for said overflow

Patch 2 is somewhat independant from the others, and could be applied
separately.

Christophe Gisquet (9):
  mpegvideo: dnxhdenc: permute 10bits content
  fate: add 10bits YUV4:2:2 test
  x86: prores: templatize 10 bits simple_idct
  simple_idct10: improve precision
  x86: simple_idct10_template: fix overflow in pass
  x86: simple_idct_put: 10bits versions
  x86: simple_idct: add pure idct functions
  x86: simple_idct: 12bits versions
  x86: dct-test: add more idcts
