This bug can't be reproduced when gfx.webrender.software set to true.

Entire frame visible on Galaxy A52s 5G, Firefox 111.1.1.

Severity: -- → S3
Summary: Incorrect VP9 Video Scale → Incorrect hardware VP9 Video Scale on Huawei Nova 5 Pro

I also cannot reproduce this on a Samsung Galaxy S10, which has the same GPU as the reporter.

We've had similar bugs in the past due to the OS providing us with an incorrect SurfaceTexture transform, so that is probably the case here. @heptadecagon, do you know if this is an old bug or whether it just recently started occuring?

Flags: needinfo?(heptadecagon)

Yeah, this may be a old bug. On ftp.mozilla.org/pub/fenix/releases/, 101.0.0-beta.1 is the earliest version that can reproduce this bug.

Thank you very much for testing that! That makes perfect sense: Bug 1731980 landed in 101. That made us do the right thing and actually apply the transform that the system tells us to apply to a video. Previously we always just flipped it upside down, which is correct 90% of the time. That bug fixed it for 9.9% of remaining devices that also need it to be scaled and tell us that correctly.

But unfortunately there is a remaining 0.1% of devices that actually only need the video to be flipped upside down, so used to work correctly prior to bug 1731980. But for some reason they tell us to apply a scale as well, so we now render the video at the wrong scale. See bug 1784109 for a previous example of this. I will apply the same workaround as in that bug for this chipset too

Regressed by: 1731980

Hi heptadecagon, would you please be able to install this apk I made. That will install an application called "GeckoView example" which is a very barebones browser, and I included a potential fix in it. Would you be able to test whether video renders correctly in it? If possible could you test a variety of codecs just to make sure fixing VP9 doesn't break anything

Comment on attachment 9327195 [details] Big Buck Bunny on "GeckoView example" (1920×1080) @jnicol "GeckoView example" renders the VP9 video correctly now. Thank you! ![Big Buck Bunny](https://bugzilla.mozilla.org/attachment.cgi?id=9327195) I have tested a H264 video and a VP8 video, "GeckoView example" also renders them correctly. Do I need to test various resolutions (480×360 to 3840×2160) ?

If you could test various resolutions that would be great, as I know the transform value can change for different resolutions. Thanks very much!

In bug 1731980, we started correctly applying the provided
SurfaceTexture transform when rendering videos. However, we have since
discovered that some devices provide an incorrect value which we must
override in order for the video to be rendered correctly. This patch
extends the existing workaround for such devices, originally added in
bug 1784109, to also be used on the Kirin 980 board.
