low ssim value when decoding hhi_burst_long.bits. random issue(test 5 times, this issue only arise 1 time), the ssim is: e.g. filename Y SSIM extreme Y SSIM average U SSIM extreme U SSIM average V SSIM extreme V SSIM hhi_burst_long.bits 0.239132 0.368341 0.720362 0.813650 0.785594 0.86527 1.

Testing Steps: ======================================================================== 1.run command "gst-launch-1.0 filesrc location=/root/media_tools/decoder/bitstreams/hhi_burst_long.bits '!' mpegvideoparse '!' vaapidecode '!' vaapisink sync=false" 2.run command "/root/media_tools/decoder/video/decoder/mpeg2decode -b hhi_burst_long.bits -f -r -o0 hhi_burst_long.bits%d" 3.judge the YUV file that create by above command to get ssim value. 3. Bisect Information: it's intel driver's issue, git bisect information is: fbbe401aa28a0b3859d587ef08f0df15a2f7c8f2 is the first bad commit commit fbbe401aa28a0b3859d587ef08f0df15a2f7c8f2 Author: Sreerenj Balachandran <sreerenj.balachandran@intel.com> Date: Wed May 28 15:02:41 2014 -0600 Fix the segfault while encoding multiple slice per frame.
