I'm using ffmpeg git on MacOS 10.13.1
In my system, I have a iGPU (HD630) and an AMD Vega64.
I can use videotoolbox to encode video on both GPU's but can't select which one to use.
When iGPU is enabled, this one is always used.
But when I disable the iGPU in bios, the Vega64 card is used.
I've encoded several video's and for h264, I want to use the HD630 iGPU because it produces better quality. But for HEVC, the Vega64 produces much beter quality and is 4 times faster.
So, it would be very nice if it is possible to switch between the available GPUS.
