Description (last modified by )
I've just compiled the latest git version of FFmpeg to use the scale_vt filter.
When using:
ffmpeg -hwaccel videotoolbox -hwaccel_output_format videotoolbox_vld -i input.mov -c:v hevc_videotoolbox -b:v 5M -vf scale_vt=640:360 -an -tag:v hvc1 ouput.mp4
It does not scale the output.
But if I add hwdownload,format=nv12:
ffmpeg -hwaccel videotoolbox -hwaccel_output_format videotoolbox_vld -i input.mov -c:v hevc_videotoolbox -b:v 5M -vf scale_vt=640:360,hwdownload,format=nv12 -an -tag:v hvc1 ouput.mp4
The image is cropped to a 640x360 scale.
I've tried using various input files (8bit or 10bit) same result.
Tested on a Mac Mini M1.
