build with the VMAF lib, I got the following error messages. I could build x265 and
VMAF separately though. I think the reason was because that Netflix changed compute_vmaf()
interface (added more input arguments) but x265 was not updated for that change.  I used the latest code for both x265 and VMAF
as of 10/26. </span></p>
