Macroblocking artifact seen on a VC1 video file

[DaveBinM]

I'm seeing a very similar issue to intel/intel-vaapi-driver#13 in this driver as well, which I was able to replicate using the file linked here: https://docs.google.com/uc?id=0B9X316MN6HHvSlNWb1ZhSGo2X2M&export=download

This is on Ubuntu 18.04.3 (kernel 5.0.0-31-generic), with intel-media-driver/19.2.1 and a Kaby Lake G processor (https://ark.intel.com/content/www/us/en/ark/products/130411/intel-core-i7-8705g-processor-with-radeon-rx-vega-m-gl-graphics-8m-cache-up-to-4-10-ghz.html). @carpalis was able to resolve this last time.

@Tianhaol could you help to check it?

Just following up on this one to see if there's any further news on this one?

Confirmed that this issue is (still) present in 20.1.1 .

@carpalis, I'm sorry to ask, but is there any chance the work here is similar to what you did to resolve intel/intel-vaapi-driver#13? 🙂 🤞

Any updates? I saw the recent label "P3" means "no customer usage". I don't know what a "customer" means for intel, but there are hundreds of posts similar to this in other communities:

Any chance this issue can be given some development cycles?

[XinfengZhang]

sorry for late response, @guowillyy could you help to check whether the patch intel/intel-vaapi-driver#234 is applicable for media-driver, from the discussion, similar issue already been fixed in intel-vaapi-driver repo by the PR

Please do what you can as this is a showstopper, pun intended, for all users of Comet Lake and newer.

Hi @DaveBinM , the file link is out of date (https://docs.google.com/uc?id=0B9X316MN6HHvSlNWb1ZhSGo2X2M&export=download), could you please help to provide a valid file link that can replicate this issue? Thanks a lot.
