[Jason Garrett-Glaser]

x264 | branch: master | Jason Garrett-Glaser <jason at x264.com> | Tue Jan 18 00:52:03 2011 -0800| [cd53fa47afadb563eefb72c137fb30bd06d26c85] | committer: Jason Garrett-Glaser

VBV emergency mode
Allow ratecontrol to select "quantizers" above the maximum.
These "quantizers" progressively decimate the source to avoid VBV underflow.
x264 is now VBV compliant even with input as evil as /dev/random.
