Description

4 years ago
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 (Beta/Release)
Build ID: 20140815004001

Steps to reproduce:

1. Start a completely clean profile to ensure it's not the fault of any add-ons
2. Go to https://www.youtube.com/html5 to verify that the HTML5 player is being used
3. Navigate to any video on YouTube


Actual results:

The video loading animation briefly plays, then Firefox crashes.
Crash report here: https://crash-stats.mozilla.com/report/index/642e20eb-3631-4421-8ce7-f63d92140816


Expected results:

The video should have played.

GPUs are an Intel HD 4000 and NVIDIA GeForce 610M. Both have their drivers up-to-date. Disabling hardware acceleration beforehand still crashes the browser, although now Windows says "Firefox is not responding" instead of the Crash Reporter coming up.

Is this your crash too https://crash-stats.mozilla.com/report/index/da7183c6-1432-4172-ba6b-a650b2140816 ?

Do the videos at http://ie.microsoft.com/testdrive/Graphics/VideoFormatSupport/Default.html also cause the crash?

That UUID is not listed in my about:crashes, so I suppose not. 

Yes, (one of) those videos causes the crash as well.

I'm not sure how useful of a datapoint this is, but the crash does not happen when running Firefox inside a VM on the same machine.

Safe mode does not improve things.

I'm not 100% sure which video causes the crash, since the entire browser just stops working, but part of the webm video appeared to have loaded and I have viewed other .webms without issue, so it's very likely one of the h.264 videos.

The crash ID of this latest crash is bp-67370869-9616-46d5-b00f-734262140818

Tracy, this isn't a high volume crash but since it mainly appears on 33 I thought you might want to take a look.

I think the reason it happens mostly on 33 is that for this version and above YouTube offers html5 video by default, as opposed to flash-based videos. The issue is present in 31 as well, but its users are less likely to come across these problematic videos.
heh, with fx33, 18 crashes on 10 installations in 28 days isn't something I have the bandwidth to investigate.  If/when it becomes a top crasher, I'll certainly set my attention to it.

That said, nyubis, please keep trying to figure out why vm works but not on hardware. what's differently configured?

Unfortunate, but I understand.

Nothing in the Firefox configuration itself seems to be different, and I uninstalled any programs that might interfere with it. My best bet is something relating to drivers, but I'm not entirely sure how VMWare handles those.

Is the OS fully updated? What about IE? Some patches for OS and IE fix things on Firefox strangely...

This dll file belongs to Windows' media foundation things, AFAICT, so I'm moving this to Core::Audio/Video.

If you toggle media.windows-media-foundation.enabled to false in about:config, does that fix the crash? (I actually think it might make it impossible to watch H264 media, and thereby "fixes" the issue, but it's worth checking, I suppose...)

It's as you thought, H264 video no longer works, but the browser doesn't crash any more. 
So if the problem exists in the WMF code, does that mean it's something you have no control over?

Thanks for confirming that.

I don't really know the video/audio code, so I can't knowledgeably answer that question, but it is at least possible that that is the case.

It's strange though, because I expect this isn't universally reproducible, or we would have noticed before now and/or there'd be more people crashing. If you can reproduce this with any HTML5 h264 video on youtube, that's pretty terrible. In other words, I'm wondering why this crashes reliably on your machine and doesn't on most other people's copies of win7 (at least, I'm assuming it doesn't). Perhaps Chris can help and/or knows of a way to gather more data? Maybe we have contacts with MS that can help?

Try toggling the pref media.windows-media-foundation.use-dxva to false.

This means we won't try to use your GPU to accelerate the video decoding, which is often where these problems lie.

Basically yes.

It looks like you're crashing right at the start of decoding. We'll be replacing the code that calls thing in a few months, so likely we'll see a change in behaviour here soon.

Setting media.windows-media-foundation.enabled back to true and media.windows-media-foundation.use-dxva to false causes Firefox to crash on the test page. Unfortunately it's one of those crashes where the Crash Reporter doesn't come up, so I can't report it.

msmpeg2vdec.dll crashed too on http://ie.microsoft.com/testdrive/Performance/FishBowl/
in SeaMonkey 2.32 (64 bit)

https://crash-stats.mozilla.com/report/index/cf82ca15-61e6-417c-929a-495bc2140904

SeaMonkey 2.31 crashed too, but older SeaMonkey 2.30 (20140722191524) is O.K. and NOT crashed !!!
(and latest FireFox on same PC too not crashed)

With media.windows-media-foundation.enabled set to false SM 2.32 NOT crashed !!!
But water is in rot color, and not in blue.

And with media.windows-media-foundation.use-dxva to false is O.K. (in blue color and NOT crashed),
but older SM 2.30 not crashed with both set to true.
Does the crash still occur today's Nightly? Some major changes were made recently to our Windows video decoding code.

I can't really say, I don't run Windows on this machine any more. For what it's worth, it works without problems on Debian.
