This issue is caused by gst-vaapi layer, not our driver issue.
Maybe parameters exist problem or data in some frame lost ,now try to find the frame which causes the problem.

Created attachment 73914 [details] [review] This patch remove inverse zigzag in gstvaapi codecparser gstvaapi codecparse handles the data with inverse zigzag, and the intel-driver alse asks for original data to inverse zigzag. Here comes the contradiction.This patch remove inverse zigzag in gstvaapi codecparser,and it can solve this issue.
We need Gwenole and Haihao's comments.
In my opinion, firstly there is one codec paser's issue, when reading matrix from bitstream, it get the normal order matrix, but if not matrix in stream, the default matrix will be loaed, but it is zig order matrix, so the output format is not aligned in these two case.
This issue has been tracking here in upstream: https://bugzilla.gnome.org/show_bug.cgi?id=693000

I pushed your patch with some minor changes (comments + indent) into gst-plugins-bad master branch. Thanks. This issue is fixed in gstreamer-vaapi 0.4.3 release. I will update git master branch soon.
Issue still can be reproduced. Libva: (staging) bfa1553c18b7b12cf1c221cafdc1784672a7b4ac Intel-driver: (staging) 04d459f88353a5be82724e648bb30ddb37286d26 Gst-vaapi: (qa) 205ae880b7696dbd76d5a2968bb858a9fa7c5958
Below files are still failed by SSIM value < 0.99, and they are passed with mplayer. bits_conf_lep_11.bits gi4_video.bits gi6_bit_stream gi7_bit_stream gi_from_tape_gi_stream ibm-bw.BITS nokia7_dual.bit ntr_skipped_v3.bits sony-ct1.bits sony-ct2.bits sony-ct4.bs tceh_conf2.bits tcela-10-killer.bits tcela-6-slices.bits tcela-7-slices.bits tcela-8-fp-dp.bits tcela-9-fp-dp.bits
retest with the lastest gst-vaapi code, still some cases failed. att_mismatch_att.bits ibm-bw.BITS sony-ct1.bits sony-ct2.bits
