Unable to read video

Hi I’m using Firefox (up-to-date) and Ubuntu 18.04, the chapter1 video about “MongoDB Documents: Fields with Arrays as Values” and in chapter2 video " Cursors" are not working with this error message : “Your browser does not recognize any of the available video formats.” (original message in French : “Votre navigateur ne reconnaît aucun des formats vidéo disponibles.”)

All others videos are working well…

Thank you by advance,


Did your try any alternate browser?
If yes are you getting same error
May be html5 video support missing in your browser or extensions or addons causing the issue
Please check these links. May help

Hi guys,
Thanks for sharing the link,
I tried with Opera, same issue, I don’t have the add-ons discussed installed and with firefox in safe-mode it doesn’t work too…
Others videos from the course are working well…
