ffmpeg | branch: master | Jason Garrett-Glaser <jason at x264.com> | Tue Feb 8 15:51:15 2011 -0800| [a97b9325cbb96bbd517a8a4c2987e893a5ba51d3] | committer: Michael Niedermayer
Update qmin/qmax values for libx264 presets
Also allow qmin/qmax to go up to 69 (the current max value for libx264). This
will have to increase when we add 9/10-bit support.
(cherry picked from commit c7ac200d15e3240972d269df768068f0e3bb9c2f)
