Firefox 43 quits when attempting to display HTML 5 video
Last modified: 2016-01-06 05:56:38 EST
Description of problem:
The new Firefox 43 build that was released today crashes when trying to display HTML 5 video. The previous Firefox 42 build (as of yesterday) was fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Go to https://www.google.com/?gws_rd=ssl#q=html+5+video+test
2. All links with HTML 5 video crash the browser
The browser crashes.
The browser should not crash and display HTML 5 video.
Not sure whether the problem is upstream or a problem with the build. If you go to the URL http://youtube.com/html5 you can see whether your browser is set up for HTML 5. Notably, mine is. Youtube does not crash the browser. It attempts to play HTML 5 video but then falls back to Flash.
This does appear to be a problem with the Fedora 22 build.
If you use Mozilla's x86_64 Firefox 43.0 build with the same profile, the following page not only loads but the bottom two videos play fine.
The H.264/MP4 video does not play for me but that is probably a separate issue.
Interestingly, Youtube HTML 5 playback with Firefox 43.0 appears to be broken for both builds.
Normally, if you go to the URL
You want to have everything checked.
It looks like the regression with Firefox 43 was with the setting
MSE & H.264
In order to turn this specific setting off, you need to adjust the about:config setting
and set it to false. With this setting disabled HTML5 video playback seems stable again.
Can you please test this package?
I have re-enabled
and this new release looks good to me. No crashes.
Thanks for your hard work.
