I'd agree, that you probably don't want to change it.
The patch "rids the first few encoded frames of their blockyness"
because the old default was 0.
I took the description from the x264enc section, which already had a
'vbv_init' parameter.

How about "This tells the encoder how much data the player will
prefetch into its vbv-buffer, before it starts playing"?
