Comment (by ponpon):

 Replying to [comment:15 thilo.borgmann]:
 thank you for the attach.
 i can build and the filter functions.
 but slow and it seems the filter uses dGPU from gfxcardstatu.
 is there a penalty in deta transher by using dGPU?

 though graphic conveter use coreimage,  it seems graphic conveter uses
 iGPU.

 sorry. i hesitated. this is because junk mails are too many since my mail
 addresss is open to public inspection by work-related matters.
 i am preparing to subscribe to ffmpeg-devel temporarily. i can test and
 root for you.
