* all: Patch from Måns Rullgård <mru AT mru DOT ath DOT cx>
"Here's a patch that adds some kind of rate control. I suppose it is by no means perfect, but it's much better than constant quantizer. It also has a very crude scene change detection that sometimes avoids a buffer underflow by reencoding oversized P/B frames as I frames." git-svn-id: svn://svn.videolan.org/x264/trunk@17 df754926-b1dd-0310-bc7b-ec298dee348c
