[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Thanks.

• Has this always been an issue, or did it work at some point then stop working?
• When crashing does the whole tab crash with a notification replacing the page, or do you just get a yellow bar at the top of the page saying a plugin has crashed?
• Is it all Amazon Prime videos that fail, or only specific ones?
• Do any other sites fail when playing video?

Comment 6

[adbuchanan]

The issue started when I updated from firefox 76.0 to 76.0.1
The whole tab crashes with a notification replacing the page.
It seems to be all amazon prime videos that fail when an ad plays before the video.
I have not experienced any other sites failing. I have played videos on netflix, youtube and disney+ since this issue began and all work fine.

Comment 7

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Based on this (and other crash reports) it looks like something is going wrong in colour conversion. Moving to graphics based on that and the rest of the stack. Gfx folks, let me know if there's any help needed from the media side.

Comment 8

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Resetting severity so this gets re-triaged.

Comment 9

[Nicolas Silva [:nical]]

Sotaro, do you know if something happened between 76.0 to 76.0.1 with the video code that could have caused invalid reads in the software YUV conversion code? Looks like it's a fairly high volume crash.

Comment 10

[Sotaro Ikeda [:sotaro]]

Hmm, I have no idea about it around gfx area. The crash happen in content process with SharedPlanarYCbCrImage. It seemed to mean that VideoData::CreateAndCopyData() was called in content process.

I tested the STR in comment 0 with latest m-c, but I could not reproduce the crash.

Comment 11

[Paul Adenot (:padenot)]

https://bugzilla.mozilla.org/show_bug.cgi?id=1635823 happened in this range. Should we be taking this software path at all?

Comment 12

[Paul Adenot (:padenot)]

Sotaro, maybe you know then answer to the question in comment 11.

Comment 13

[Nicolas Silva [:nical]]

There are very few occurrences of this crash before 76.0.1. I see all desktop GPU vendors. The strongest correlation is obviously software video decoding (the backtrace of the crash is on the software decoding path). I suppose the effect of bug 1635823 is that more users ended up on software decoding but it is surprising to me that we had so few instances of this before 76.0.1 if this is simply a bug in the software playback code.

Comment 14

[Jessie [:jbonisteel] pls NI]

Bryce, out of curiosity, have you been able to repro this crash?

Comment 15

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

I have not reproduced this.

I don't know if bug 1639258 is related, but it has some similarities.

• recent increase around 76.0.1 (though I see this has a number of reports from 75)
• happening in lower level colour conversion/decoding code.

My assumption is it's not related at this stage, but bring mention it in case something stands out to anyone else.

https://bugzilla.mozilla.org/show_bug.cgi?id=1635823 happened in this range. Should we be taking this software path at all?

When hw decoding is not used, we need to use software decoding. And when we want to convert YUV->RGB by software, gecko needs to use gfx::ConvertYCbCrToRGB().

(In reply to Bryce Seager van Dyk (:bryce) from comment #15)

I don't know if bug 1639258 is related, but it has some similarities.

Almost every crash in bug 1639258 is a cpu with "family 23 model 1 stepping 1".

I looked at crashes in crash-stats in I422ToARGBRow_AVX2 based on the crashes in comment 4, they seem to have a much wider spread of cpus.

Comment 18

[Sotaro Ikeda [:sotaro]]

Crash happened in I422ToARGBRow_AVX2().

In I422ToARGBRow_AVX2(), some registers were used like the following on x64

• width: r11(decremented for each iteration)
• y_buf: RCX(incremented for each iteration)
• u_buf: RDX(incremented for each iteration)
• v_buf: R8(befre iteration, store diff between v_buf and u_buf)

From the above and register values of crash reports, video width seemed like the following. And crashes seemed to happen during first iteration in I422ToARGBRow_AVX2().

• 1280(0x500)
• 1920(0x780)

And I wonder if the crashes might happen around READYUV422_AVX2.

vmovq xmm0,mmword ptr [rdx]
vmovq xmm1,mmword ptr [rdx+r8]

Comment 19

[Sotaro Ikeda [:sotaro]]

From crash reports, when width(r11) was 1280(0x500) and crash happned, "u_buf address(RDX)" - "y_buf address(RCX)" was always 0xA83C0. It seems that crash happened at same place when width was 1280(0x500). Hmm.

Comment 20

[Sotaro Ikeda [:sotaro]]

During looking into related soure, I noticed that YCbCrTextureClientAllocationHelper::IsCompatible() has a problem. And Bug 1639874 was created.

Comment 21

[Pascal Chevrel:pascalc (PTO until April 26)]

Sotaro, do you think this bug was fixed by the patch in bug 1639874 ? Thanks

Comment 22

[Tim Spurway [:tspurway]]

S1 or S2 bugs need an assignee - could you find someone for this bug?

Comment 23

Yes, it seems to be fixed by bug 1639874 fix.

Comment 24

[Sotaro Ikeda [:sotaro]]

:adbuchanan, can you check if the problem is addressed for you?

Comment 25

[adbuchanan]

It appears to have been fixed in 78.0beta as far as I can tell.

Great. Thank you for the checking!
