Often , I have had this issue where random YouTube video wo n’t work on Firefox , while they work finely on Google Chrome . A flake of Google search and turn out TV that operate on license codecs like HEVC-265 do n’t work on Open Source web internet browser like Firefox and Vivaldi . For instance , I usedVivaldiand it only supports free loose - source video codecs . So , it does n’t support MPEG-4 and HEVC-265 . But , there is a workaround for Chromium - based browsers and here ’s how you fix YouTube video recording not playing on YouTube .
Which codec your internet browser does n’t support
Before we get to the fixture , it is important to see the problem . YouTube recently moved from ostentation videos to HTML5 embedded video actor . So , you do n’t require Adobe Flash to go videos on YouTube anymore . Your vane web browser has to be HTML5 compatible which most of them are . But , they do n’t support all the video codecs . To check what codecs your internet browser does n’t corroborate , head over to theHTML5 test website .
On the proper - hand side , you will see all the video codecs supported by your web web browser . In my case , I am using Vivaldi and it does n’t patronage MPEG-4 and H.265 which is evident from the HTML5 test below .
How to Fix YouTube Videos Not Playing On Linux
1. Chromium-based browsers
You need to instal the licensed codec . you’re able to use the following command or just run Vivaldi on the command job if you use the Vivaldi internet browser .
Head over to the end and type “ vivaldi ” and hit Enter . It will open up a unexampled browser app window and in the terminus , it will tell you the codecs found . Initially , there will only be undecided codecs installed and it will prompt you the command to set up the proprietary mastery . Use that dictation or you’re able to directly paste the next command .
If the above command does n’t work for you , you may or else download the “ .deb ” data file fromthis location . Once download , double - select the file and add the additional codecs . After installation , restart the chromium - web browser app . In my example , it is Vivaldi . Play the picture and now it should work .
2. Firefox
In the shell of Firefox , all you have to do is update to the latest variation of Mozilla Firefox for your Linux distro . But , there is a small caution . Firefox supportsOpenH.264which is different from proprietary HEVC 264 . So , the special video I was testing played well on OpenH.264 . However , not all H.264 videos would spiel on OpenH264 and there is no workaround to get the proprietary H.264 and H.265 work on Firefox .
