[workaround] Fiirefox stops to play Youtube after a second

student975 · 2015-08-14 13:25:36

Hi!

After upgrading to v.40 Firefox stops to play any Youtube video after a second (or few seconds, or part of second) regardless video itself (resolution and so on) - I haven't met a video with different behavior, they all stops. After seeking forward or backward playing back takes pace again during second or so, and stops again.

Any hints to cure?

Are you using the html5 player? Do you have all the needed optional dependencies installed? Are you using firefox from the repos?
Does it work on e.g. vimeo?

From what I know, this happens if you have enabled the options to utilise mp4/webm/whathaveyou in order to get full hd youtube playback. There's a reason these aren't enabled by default, they aren't completely stable yet. And I experienced that with earlier versions of FF already if the mentioned settings have been enabled

Yes to all question except for the last one. If I enable webm, playing back doesn't stop, but I haven't a sound.

On vimeo I haven't a sound, just video is playing back.

Chrome hasn't any problems at any use case.

mp4/webm are disabled at the moment (I have tried them also).

And - yes, I have tried to start Firefox in safe mode with the same result.

To be sure it isn't video driver problem, I have switch from proprietary NVIDIA driver to nouveau, and the issue takes place exactly the same way.

This has fixed it for me. I had changed some values in about:config previously for testing HTML5 playback and since Firefox 40, if these values are set then I had the same issue you described.

The solution was to go to about:config and set these entries back to their default value:

media.mediasource.enabled => false
media.mediasource.webm.enabled => false

Basically, just make sure every value that appears when you search for "mediasource" has its default value (does not appear in bold).

@spiridow,

The thing is, the issue appeared with default settings as you wrote.

The problem is: with "media.mediasource.enabled => false" and "media.mediasource.webm.enabled => false" the only resolution I can get is the lowest possible, 360p.

I still haven't resolved the issue. But today my mother told me she has got the same problem (I maintain her Arch installation remotely).
So, it isn't personal issue. And it is interesting, her computer has absolutely different hardware (motherboard, processor, audio, video, ...).

Has anybody got some new information regarding the problem?

Another additional information: I have installed VirtualBox guest Manjaro, and Youtube plays without any problems. So, the issue is in local Arch installation. And it isn't Firefox config as far as I have tried safe mode.

Also I have tried being logged in with different (test) account, the issue still takes place. That is the issue doesn't depend on user level configuration.

Also have tried with Midori, and the last one plays Youtube without problems also.

Is gst-vaapi installed? That one used to give problems, nothing in the terminal if you start firefox in one?

I have tried with and without gst-vaapi with the same result.

To be a pedant, the package is named gstreamer-vaapi

Also have tried firefox-developer from AUR (v.42.0a2 (2015-08-26)) - the issue still occurs.

As well as lts kernel. You are right, with the same result

If to guess the issue will be resolved in future Firefox version, at the moment it is possible to use https://addons.mozilla.org/en-US/firefo … sh-player/ to temporary dirty workaround the issue.

Arch Linux
