Again I am wondering if there is interest of having gl and/or Vulkan filters in ffmpeg, along with direct transfer support where the source/target is on gpu, as with many of the hwaccel targets?

That is what we do in our pipeline to get high throughput, and i‘d be happy in pushing some of that back into ffmpeg.
