Probably something with the the frame crop metadata.

Comment 3

[Jean-Yves Avenard [:jya]]

From talking to roc, this is due to our dxva compositor not handling offsets. Which vp9 videos often uses

@Ralph Giles:   The regression window is provided in comment 0. Btw, I got the same regression window

[Anthony Jones (:ajones, :kentuckyfriedtakahe, :k17e)]

Milan - who fixes compositor bugs?

Comment 6

[Jean-Yves Avenard [:jya]]

I have a suspicion on what's going on with the dimensions returned by WMF. I'll look into it later today. Still need to implement margins support with dxva

Comment 7

[Jean-Yves Avenard [:jya]]

Attachment: Only use container calculated dimensions

Use calculated dimensions found in SPS rather than the values returned by the WMF.
Turned out that the attribute MF_MT_FRAME_SIZE is actually the stride size rather than the usable size and previously we would use the values returned by GetPictureRegion. I got incorrectly stirred by the name of the attribute and the name of the variables.

Looks like we'll need a similar change to media/gmp-clearkey/0.1/WMFH264Decoder.cpp.

no it's fine there.
It calls wmf::GetPictureRegion(aMediaType, pictureRegion); which does the proper thing (or at least get the right value).

The alternative approach would be to re-add the use of GetPictureRegion().. I'm in two mind about it, as it guarantees that there's no regression over the earlier code which has worked fine for a long time now

Tracking as this is a high end-user impact regression.

Jean-Yves, should we consider uplifting this to Aurora44? Thanks!

Alice0775 White, could you please verify that this issue is fixed as expected on a latest Nightly build? Thanks!

Approval Request Comment
[Feature/regressing bug #]: 1222201
[User impact if declined]: Visual corruptions in MP4 data on windows (obvious when using YouTube)
[Describe test coverage new/current, TreeHerder]: In central for 2 weeks.
[Risks and why]: Low, however the fix may not be sufficient and there may be a need to revert the entire set of changes in the WMF which were made to support the intel hardware decoder (now disabled by default)
[String/UUID change made/needed]: None

I cannot reproduce the problem on latest Nightly45.0a1 anymore.

But, of course, I can still reproduce the problem on Aurora44.0a2.

Thank you for doing the verification! We will uplift the fix to Aurora44.

This fix has been verified on Nightly, it makes sense to uplift to Aurora44.
