.ogv Crash

Unread post by EbonJaeger » 2017-06-24, 18:43

Hello,

Not sure if this is exactly the correct place for this, and if it isn't please feel free to move it.
When a webpage contains a video in the .ogv (a member of the OGG family) format, Pale Moon crashes. I discovered this when someone embedded this in a forum post on a forum I frequent. Upon investigation (in Firefox), the video is the culprit. A direct link to the video is here: https://www.quirksmode.org/html5/videos ... _bunny.ogv

I haven't yet had a chance to test this on Windows, so I suppose being Linux, it could be a missing codec problem. Even so, I would expect some sort of error to appear, and not the entire web browser to crash.

ETA: This indeed does not happen on Windows 10; the video plays fine there.

No problem with your link in Xubuntu 16.04! Video plays just fine!

Most interesting... That further complicates things. For the record, I am using Solus OS. I'll do some more poking around...

Are there any sort of crash logs that might be of any use for tracking this down?

It doesn't crash for me either. I'm on Linux Mint 18.2. Are you running the latest version of Pale Moon? Is your OS up to date?

See if you get the crash in safe mode.

Huh. After restarting in safe mode, the video plays just fine, and no crash happens.

For reference, Pale Moon is version 27.3.0 on my system (64 bit), and there are no OS or package updates available for install.

ETA: Once my new Linux Mint 18.1 VM is ready I'll install my addon's one by one to see if that's doing this.

Safe mode does more than just disable add-ons, so this may also be a video driver issue.

Noted. Going through add-ons is still a good starting point though, right?

It would appear that it's the theme I'm using that's somehow doing this (I was using the BlackFox V2 (2.5.1) theme). First thing I did was switch to the default theme, restart PM, and the video plays as normal. As for how a theme could cause the browser to crash when a certain video format is in the page, I am not quite sure.

Semi-educated guess, no having looked at the theme myself:
If an incompatible theme changes the browser XUL and causes an invalid layering of drawing surfaces for accelerated video, it can cause a crash.
