[FFmpeg-devel] avcodec/proresenc_aw : add support for prores 444

[Martin Vignali]

Hello

Patch in attach add support for prores 444 profile in AW prores encoder

Need to be apply after patch in discussion "avcodec/proresenc_aw
improvments"

Speed (from prores 422 HQ file -> Prores 444)

./ffmpeg -i prores422hqfile.mov -pix_fmt yuv444p10 -c:v prores -an
-profile:v 4 res_aw.mov -y
==> 25 fps

./ffmpeg -i prores422hqfile.mov -pix_fmt yuv444p10 -c:v prores_ks -an
-profile:v 4 res_ks.mov -y
==> 10 fps


001 : Add support for Prores 444 (without alpha)
002 : change the frame flag in header part, to be the same than the
official encoder in 422 mode
(and update fate test)
