It's not that the VBV constraints were causing the hiccup, but that
your method of multi-process encoding can't guarantee VBV-compliant
output, which is a problem you didn't seem aware of.

I'm not familiar with the process of combining h264 streams like you
suggest. If you think the decoding/resizing step is the bottleneck,
have you considered doing that outside x264 in a multi-threaded
process and piping raw video into x264?
