I think that what he was suggesting is:

1: First pass: video encoding pass 1, audio encoding pass -of rawaudio.
The video is discarded, but that's okay because you weren't going to do
anything with that pass's video anyway - and the creation of the
statistics file should not, I think, be affected by the fact that you're
using -of rawaudio.

2: Second pass: video encoding pass 2, ignore the audio, -of rawvideo.
This time the audio is discarded, but thats okay, because you already
have the copy which was output in the previous pass.

 From there, proceed through your muxing steps as normal. Admittedly I
haven't tested this, but I see no reason offhand why it shouldn't work.
