Rationale: - Slower then other encoder - Less configurable - Does not support alpha profile - Does not set interlaced flag - Worse output quality - No need for 2 encoders Signed-off-by: Paul B Mahol <onemda@gmail.com> --- doc/encoders.texi | 5 +- libavcodec/Makefile | 1 - libavcodec/allcodecs.c | 1 - libavcodec/proresenc_anatoliy.c | 616 ---------------------------------------- 4 files changed, 1 insertion(+), 622 deletions(-) delete mode 100644 libavcodec/proresenc_anatoliy.c
