Compare to Master branch, 6 of 60 couldn't get the bit match result with the SW. zhixin, please help to attached the 6 files which failed the test. If the clips size are too big, you can just give their names. The MVC clips can be found on the link http://tinderbox.sh.intel.com/media_streams/mvc/ (In reply to Focus.Luo from comment #2) > zhixin, please help to attached the 6 files which failed the test.

It cannot bit match when doing MVC decoding test 1. Testing Steps: ======================================================================== 1.use following command to get hardware decoding md5 "gst-launch-1.0 -q filesrc location=/media/mvc/MVCICT-1.264 ! vaapiparse_h264 ! video/x-h264,stream-format=avc,alignment=au ! vaapidecode ! videoconvert ! fdsink 2>/dev/null | /opt/X11R7/ffmpeg/bin/ffmpeg -v 0 -f rawvideo -s 768x480 -pix_fmt yuv420p -i pipe:0 -filter:v crop=720:480:0:0 -f md5 -" and get the hardware decoding md5 is 96365cd72678edbfa313f1cb1e889d3e the software decoding md5 is 394e14805bad1626ea4210008bcfe3ee 2.
