[SOLVED] Greenscreen in Firefox when playing HTML5 Videos

Hi! I don't think someone had this question before, google doesn't give me any good answers either. Move if this is the wrong section.
When I play HTML5 Videos like the Youtube HTML5 player I get a greenscreen, but I get sound.
Any info you need to know ? Just say it and I'll deliver.

pacman -Qs flashplugin

See if flashplugin is installed, that's all I can think of.

Why would it make a difference?


@heldiho53
Is your system up to date? What is your graphics hardware, which codecs do you have installed? When did it start happening? What have you changed since - post which packages have you updated etc.

HTML5 can be used as an alternative to Adobe Flash.[1] Both include features for playing audio and video within web pages

Even if flashplugin is installed, I think YT won't use it with the current firefox, you have to switch manually https://www.youtube.com/html5

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

I just upgraded to Firefox 34.0.5 and video stopped completely working on Youtube, with audio only on Vimeo. Downgraded back to 33 and works fine. Anyone else having the same issues?

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

Right after the upgrade I had problems with youtube too. Video was not loading not even the player showed up. But after reboot everything was fine. Did you try that already?


I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do.  (Gune | Titan A.E.)

Didn't reboot. Will re-install 34.05 and try later on.

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

What is your graphics hardware, which codecs do you have installed? Try a fresh firefox profile with all add-ons disabled.

Works fine on my firefox 34 and firefox-nightly from the AUR (version 36).
I'm running 32-bit Arch with [testing] on an old intel integrated card.


Edit: Are you sure you're using flash and not html5?

I am facing the same problem. Rebooting didn't help. Downgrading though works.

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

Maybe you changed something in about:config that used to work but now it breaks yt?

skip says he can't use flash and heldiho53 says it broke html5.
Has anyone tested it with their add-ons disabled? What about e.g. webkit-based browsers?

You were right, it seems that flashblock add-on is not compatible with the new firefox version yet. After disabling flashblock, videos are loading fine.

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

Some people on the internet said they either get a green background or a black one, but they can still hear the audio, see the player buttons and the seekbar, can interact with them and even see the thumbnails on the seekbar on mouseover.
Others said that with flash (not html5) they get just a black rectangle, no player, no audio.
It seems some users had this problem even with firefox 33, but at least on Arch it started with firefox 34.

Indeed, when I enabled flashblock (which is marked as incompatible with firefox 34) I got the black screen.

I had a similar problem. Fixed it by uninstalling gst-vaapi (Intel HD4000 here).

Are you talking about the firefox 34 issue?

No, this happened in previous versions. Haven't tried installing gst-vaapi alongside FF 34.

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

I disabled flashblock and it's working. According to the Add-Ons settings page it is not yet compatible with 34.05.

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

I feel a bit guilty, because I always recommend the Disable Add-on Compatibility Checks add-on, which stops firefox from automatically disabling extensions that are not compatible with the new browser versions. I don't recall having any problems with it: usually they either worked or not, but didn't break any other stuff. Sometimes enabling a big, complex add-on, like pentadactyl, resulted in a few minor glitches, that's all.


Let's blame Allan :-)

Re: [SOLVED] Greenscreen in Firefox when playing HTML5 Videos

Thx all! Just to re-confirm that even in latest Firefox (i.e. 42) unistalling gst-vaapi resolves the issue of "green screen" in youtube/html5 videos.
Changing the color depth, as I remember an old recommendation was, didn't do the trick...
