[Bug 1916301] Re: I can't play live videos on YouTube (problem with live transmission) - Ubuntu 18.04.5

[Piotr]

Today I updated my firefox to the newest version 86.0. Bug still exists.

** Description changed:

  Dear Launchpad Team,
  
  I can't play live videos from Youtube. I have problem only with live
  transmission. Normal videos works fine. I noticed that I also have this
  same problem on Focal (now I checked this on Bionic - Ubuntu 18.04.5).
  On Lubuntu 18.04.5 on other machine I don't have this problem. I can
  play on Lubuntu all Youtube videos. What is a problem? Do you know? I
  think that by default Ubuntu have not necessary package to play live
  videos on Youtube. Have I right or this is a bug? On Answers section on
  launchpad anyone can't tell me if it is a bug so this is why I report
  this bug now. If it is not a bug I am very sorry and you can delete this
  report now.
  
  Example I have problem with this video:
  https://www.youtube.com/watch?v=21X5lGlDOfg
  
  I used debugger by youtube and this is output of this:
  
  "debug_error": {
      "errorCode": "html5.unsupportedlive",
      "errorMessage": "Ten format wideo nie jest obsługiwany.",
      "Nx": "HTML5_NO_AVAILABLE_FORMATS_FALLBACK",
      "cj": "","
  
+ If it is a bug can you fix it?
