I having performed an install running from a CD only of Ubuntu 18.04 AMD 64 with SHA 256 5748706937539418ee5707bd538c4f5eabae485d17aa49fb13 ce2c9b70532433 running Firefox 61.01 and noticed it does not run any Youtube videos becuase it is missing HTML5.

I do not understand why HTML5 is not included is this correct?

Video stuttering on YouTube was fixed in Firefox 64.0.2 if anyone is experiencing that problem.

Is Firefox html5 dependant on the operating system? Or should it be built in to Firefox?

I'm not sure how necessary it is to do this but go to https://www.youtube.com/html5 to check that you have set the browser to use html5 as default player.

I have performed the check from youtube nad it shows H.264 and MSE & H.264 with a red exclamation mark. This is after I performed a update with "Software updater"

How can I identify the missing components? I have another workstation that does not have this problem.

You might also have to install package libavcodec-extra to get the codecs:


sudo apt install libavcodec-extra
Also if those streaming services use DRM, you must enable DRM in Firefox's settings: Preferences -> General -> Play DRM-controlled content

I appreciate the suggestion but I don't understand why Firefox on a updated operating system is unable to play live videos from Youtube such as https://www.youtube.com/watch?v=JUCekz5k9E4. Other Youtube videos play but Live items do not. What is wrong with the newly installed Ubuntu with Firefox?

Because it is an old version of Firefox. The current version should be 64.0.2.

Try updating, or installing it from Mozilla. https://www.mozilla.org/en-US/firefox/all/

No. Initially a new install starts with version 61.01 but after updating as of Jan-19-2019 Firefox was upgraded to version 64.0 and the same problem occurs. I tested playing live youtube links like "https://www.youtube.com/watch?v=JUCekz5k9E4" on a Mac OS running Firefox 61.01 and it works which suggest the Ubuntu from a fresh install should play.

In Ubuntu youtube live doesn't run on either versions of Firefox on a newly installed Ubuntu 18.04.1 LTS

Try 64.0.2?


Fixed video stuttering on Youtube (bug 1513511 (https://bugzilla.mozilla.org/1513511))

REF: https://www.mozilla.org/en-US/firefox/64.0.2/releasenotes/

You could also try Help > Restart in Safe Mode or a test profile.

Provide a link to a video that doesn't play. Happy to check it out.

It appears that Ubuntu 18.04.1 LTS does not come with FFMPEG preinstalled on the intial installation of the operating system is this correct?

To correct the problem I had to install "ffmpeg" I used the command "sudo apt install ffmpeg"

Is FFMPEG not installed by default with Ubuntu 18.04.1 LTS which has been fully updated?

To correct this problem you have to install ffmpeg using the following command.

sudo apt install ffmpeg

I placed this already on this site but it was removed.

To play most media you need something from the restricted-extras package(codecs etc) IIRC you need some gstreamer packages not installed by default to play youtube on Firefox (these will be pulled in if you install restricted-extras)


sudo apt install ubuntu-restricted-extras

This is one of the first things I install whenever I set up Ubuntu.

To correct the problem you have to install ffmpeg for youtube live and others to run

enter the following command

sudo apt install ffmpeg

Should ffmpeg be installed by default in Ubuntu 18.04.1 KTS

Can anyone tell me if FFMPEG is installed by default on Ubuntu 18.04.1. LTS?

No, it's not in my Ubuntu 18.04.1, so it wouldn't be in a default install.

No, you need ubuntu-restricted-extras.

the ubuntu-restricted-extras adds a litle more than I need. I don't remember installing anything special for video in my 16 version of Ubuntu and it worked.

Does the libavcodec-extra allow you to play Youtube live videos?

On my Ubuntu 18.04.1, I can play all the YouTube videos (including the eaglets in the nest you linked in post #8) and don't have libavcodec-extra installed, so it must not be necessary. I've not found any that won't play.
