Summary of the bug:
When encoding with the h264_videotoolbox encoder on macOS, a warning is
given that says "No device available for encoder (device type videotoolbox
for codec h264_videotoolbox)". Since this message is confusing to users
and potentially sounds like a software fallback is being used or something
isn't configured correctly, it should be removed. Issue is similar to
#6492.
How to reproduce:
{{{
% ffmpeg -f lavfi -i smptebars=size=1280x720:rate=30 -c:v
h264_videotoolbox -color_range jpeg -pix_fmt nv12 -t 5 output.mp4
}}}
Confirmed on Macbook with Intel Core M CPU ; integrated GPU.
