Bug Info
------------------------
HRD failed because parameter failed to passed by the avcenc tool for the HRD testing, it is caused by avcenc tools not HRD algorithm/setting in driver.

1.   xinit &
2.   avcenc 1920 1080 /home/encoder/encoderbitstreams.bak/1080p_blue_sky.yuv
/tmp/1.264 fb=20000 mode=1
3.   Analysis the 1.264 file with Elecard Buffer Analyzer, then HRD test
passed.
4.   avcenc 704 576
/home/encoder/encoderbitstreams.bak/CITY_704x576_30_orig_01.yuv /tmp/2.264

Before used Yakui's latest patch(ww21.2) for libva, found the buffer over flow issue by using Vega for HRD buffer analysis for D1 resolution. (See more from the attached files) 
After the patch, the issue gone. So close the bug.
