 Hello,
  I am using ffmpeg version N-56143-gd1a1656, when i set threads 8 and
 trying reencode like : hi-res source -> filter
 (postprocesor,scale,unsharp,gradfun) -> output , then i see only one core
 is busy.
  Adding frame multi-threading for whole filter line would be welcome, as
 that would allow filters that can't generally use slice threading to
 benefit of multiple cores like in my case
