ffmpeg | branch: master | Timo Rothenpieler <timo at rothenpieler.org> | Wed May 11 10:34:31 2016 +0200| [3a9df7dfec89fadfee9e814e6adb2706908dffa4] | committer: Timo Rothenpieler

avcodec/nvenc: Generate bufferingPeriod/pictureTiming SEI

For some unknown reason enabling these causes propper CBR padding,
so as there are no known downsides just always enable them in CBR mode.
