--- Comment #13 from Fei <fei.w.wang at intel.com> ---
I removed "lose frames" judgement from our test system, and get 3 fail case:
1./media/mvc/MVCICT-1.264
2./media/mvc/MVCICT-2.264
3./media/mvc/MVCSPS-2.264

With "fec82052d54daf1338f30d655a12fe6a72ea0a7f", only item 1 and item 2 fail.
Item 3 pass.

steps:
1. $tools_path/jmvc8.5/bin/H264AVCDecoderLibTestStatic /media/mvc/MVCDS-1.264
a.yuv 2

2. gst-launch-1.0 -v filesrc location=/media/a.yuv '!' videoparse format=i420
width=640 height=480 '!' vaapih264enc num-views=2 keyframe-period=30 '!'
filesink location=/tmp/gstEncJMVCdump.264

3. $tools_path/jmvc8.5/bin/H264AVCDecoderLibTestStatic
"/tmp/gstEncJMVCdump.264" "b.yuv" "2"

4. YSNR=$tools_path/metrics_calc_lite.ia32e -i1 a.yuv -i2 b.yuv -w 640 -h 480
-nopfm psnr y
   USNR=$tools_path/metrics_calc_lite.ia32e -i1 a.yuv -i2 b.yuv -w 640 -h 480
-nopfm psnr u
   VSNR=$tools_path/metrics_calc_lite.ia32e -i1 a.yuv -i2 b.yuv -w 640 -h 480
-nopfm psnr v

5. Only YSNR&USNR&VSNR all more than 40.0, then it pass, else it fail.

6. item 1 & item 2 YSNR is about 39.0+, Item 3 YSNR is 27.0+ with this patch.
