Comment (by xamarin):
However disabling audio channel for output, there is no progress
indication on time or speed, only on frame:
{{{
% ffmpeg -i input.mp4 -an -c:v libvpx-vp9 -b:v 1000k -r 25 -pass 1 -f null
NUL && ffmpeg -i input.mp4 -an -c:v libvpx-vp9 -b:v 1000k -r 25 -pass 2
video.webm
...
frame= 1199 fps=132 q=0.0 size=N/A time=00:00:00.00 bitrate=N/A speed=
0x
}}}
