[FFmpeg-devel] avcodec/proresenc_aw : add interlace encoding support

[Martin Vignali]

Hello,

Patchs in attach add interlace encoding support to prores aw encoding

Use +ildct flag to switch between progressive and interlace encoding

Use AVFrame flag to switch between tff and bff frame organization.
If AVFrame->interlaced value is not set to 1, but +ildct is set (interlace
encoding of progressive frame), define field order to top (most common case
for prores file)

user can still use setparams filter, to force bff for progressive input if
need.

Pass fate test for me (x86_64, mac os x)

Martin
