failed case

Test Env:
============================================
Platform:               SKL/APL/KBL
Arch:                  x86_64
Kernel:            4.10.0-rc2-mainline
libva            b9a72b9d8ca14e159a67c368d966ed6276f49bc9 (1.8.4 pre1)
libva-intel        c3110dc5a57f1fa174b5605ea6e36fdae3c7333c (1.8.4 pre1)
gst-vaapi        9397cd7d4d487141346dbe28e1c21897960862b0


Reproduce Steps:
============================================
Take 720p5994_parkrun_ter.yuv-4-2-cqp for example:
inputfile: 720p5994_parkrun_ter.yuv-4-2-cqp
tmpqpbr=cqp
YUVFILENAME=720p5994_parkrun_ter.yuv
j=720p5994_parkrun_ter.yuv
QPVALUE=4
targetbitrate=4
MODE=2
intra_period=30
b_frame_num=2

1. Setup gstreamer env and export them:
export PATH LD_LIBRARY_PATH PKG_CONFIG_PATH GST_PLUGIN_PATH
2. Encoding raw yuv to 264 file by the commands:
gst-launch-1.0 -v filesrc
location=/media/encoderbitstreams/720p5994_parkrun_ter.yuv '!' videoparse
format=i420 width=1280 height=720 '!' vaapih264enc rate-control=cqp init-qp=4
keyframe-period=30 max-bframes=2 cabac=true '!' qtmux faststart=true '!'
filesink location=/home/work.dir/AVC_encoding/720p5994_parkrun_ter.yuv.enc.mp4
3. Decoding the output 264 file by ffmpeg:
cd /home/work.dir/AVC_encoding/
/opt/X11R7/ffmpeg/bin/ffmpeg -i 720p5994_parkrun_ter.yuv.enc.mp4
720p5994_parkrun_ter.yuv.jm.dump.yuv
4. Compute psnr between original .yuv and the loop-dumped .yuv.dump.yuv:
YSNR=`/GFX/Test/Infrastructure/infrastructure/tests/media_tools/encoder/metrics_calc_lite.ia32e
-i1 /media/encoderbitstreams/720p5994_parkrun_ter.yuv -i2
720p5994_parkrun_ter.yuv.jm.dump.yuv -w 1280 -h 720 -nopfm psnr y |awk -F '<'
'{printf $2}' |awk -F '>' '{printf $2}'`
YSNR=' 42.93544'
 echo 720p5994_parkrun_ter.yuv 1280 720 604 4 42.93544 56.45263 56.64170 197555

5. Compute corresponding psnr from that of windows driver by calculus of
interpolation:
lin_bitrate=202296320.0
winx0=176782124.0
winx1=138841163.0
winx2=104478226.0
winy0=54.4707
winy1=50.83775
winy2=47.35079
winy1=9.5752714329e-08
winy2=-7.91344861697e-17
winy=56.7856342091
lin_psnr=42.93544

6. Got FAIL by PASS standard winy-lin_psnr<=3db:
winy-lin_psnr>3db
