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.

after reboot test machine, cannot reproduce this problem anymore. this problem found on the nightly test. before running this case, the test machine already ran A large number of tests case. so maybe this fail depend on other problem. change Importance from high to medium as it's very difficult to reproduce.
According to comment 1, closed it as invalid. Feel free to reopen it if you can reproduce it again.
use command: mplayer -nosound -fps 30 -vo vaapi -va vaapi hhi_burst_long.bits to reproduce this problem. sometimes(test 20 times, only arise 1 times) mplayer will display following message.

We can't and won't help unless you provide this information when reporting a possible bug.
it's mplayer-vaapi's issue. not our bug. so close it, only test the two cases with gstreamer.
