Nice to see someone's working on it. You beat me on it, the book on mp4
is still not delivered :-(. Maybe it can be helpful later, to clear up
the details, it looks like the ffmpeg mp4 muxer still lacks quite a few
things.

Is this the one for making b frames "work"?

Okay, nice.

Would this by any chance also fix the problem where MP4Box segfaults on
extracting raw h264 from mp4's muxed by ffmpeg? Can you check this
otherwise?

Do you have any means to check the validity of the stream produced by
ffmpeg, I guess something like Quicktime player? I don't have windows
nor macos, so for me it's going to get difficult to check, or
suggestions?
