[Libva] H264 CBR Encode with libva-intel-driver

[Jonathan Short]

Hi,

I'm using libva-1.1.1 with libva-intel-driver-1.0.20 to encode h264 
on SandyBridge / QuickSync.  Using the avcenc test program as reference, I 
have encoding working, but i'd like to use CBR rather than VBR.  Does 
this driver support CBR, and is there any example code or documentation 
showing how to set the bitrate for the encode?

Thanks,

Jonathan
