When passing the first pass arguments to ffmpeg (-pass 1 -f null /dev/null), there is no time/speed recorded for the analysis:

ffpb doesn't seem to be able to report on this, and just sits at 0% for the entirety of the first pass:
2021-03-18 19-23-22.mkv: 0%| | 0/416340 [03:56<?, ? frames/s]
Which, it doesn't fail to pass any arguments, etc. so it's technically working, it just can't get any info from ffmpeg to display. Is there something that I'm missing that could be passed to enable status on firstpass analysis?
