[FFmpeg-user] vulkan video

[Daniel Oberhoff via ffmpeg-user]

Hello,

I saw recently on phoronix that there was a vulkan video branch. Unfortunately 
that seems to have grown stale. Is there any chance vulkan video will make it 
into ffmpeg any time soon? I could also help if help is needed. We could really 
use that.

Best

Daniel

Definitely not crop, that will remove part of the image.
Instead, pillarbox it, using the pad filter, if needed in combo with scale.
