Could I ask what on earth is the point of this????????

If you're encoding the audio file with lame ahead of time, you already
know the audio size. Therefore, using the "audio pre-pass" with -ovc
frameno is totally worthless, and it may even be buggy with
-audiofile. Instead, you can just use -audiofile in pass 1/2 to read
from audiodump.wav.mp3.
