Bug 506542 – x11-drivers/xf86-video-intel-2.99.911[sna] www-client/firefox-bin-28.0-r1: Embed WebM video blinks on playback

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Amadeusz Żołnowski (RETIRED) 2014-04-02 11:51:07 UTC]

After upgrade to 28.0 HTML5 YouTube video player doesn't work good anymore.

Reproducible: Always

Steps to Reproduce:
1. Go to youtube.com/html5
2. Switch to HTML5 player
3. Pick up some YT video and watch
Actual Results:  
Video blinks and some artifacts show up. For me it's frequently enough I am unable to watch it. The sound is OK.


www-client/firefox-bin-24.4.0 doesn't have this issue. I've downgrade firefox-bin to this version and it's all fine.

Just to note:

I tested this with latest firefox 28.0-r1 and I am not able to reproduce your issue. Anyone else have it?

This is very much an issue, I will get the bug report sumbitted upstream shortly.

If you're testing it on YouTube, are you sure you use HTML5 player and not default Flash player?

The problem still occurs for me with 28.0-r1.

And to note, I've got Intel's graphics card.

when I was performing tests I joined html5 trials, so I am sure it was on. My GPU is nvidia 8600m. Some test was also made on vimeo as vimeo has moved by default to html5.

My own temporary solution is use my firefox-30.0_beta1.ebuild to build with gst 1.0 support to use gst-plugins-vaapi,when I unmerge gst-plugins-vaapi to use software decoding,it still blinks.

OK, so Arch ran into this issue as well.

It's not a firefox bug, but rather a bug affecting xf86-video-intel-2.99.911 and gstreamer-0.10 and possibly something else within firefox-26 and above.

Is there anyone having this bug that *isn't* using xf86-video-intel?  (this includes those with Nvidia Optimus that aren't in discrete mode)

As the upstream bug is now fixed I am marking this as fixed too. Please reopen if you still see the problem.
