I installed the new Raspberry PI image of Focal but I am not getting youtube videos on Firefox (nor Chromium). The video starts buffering and then a message appear on top of the video that says: "If playback doesn't begin shortly, try restarting your device."
I should say that I have another RPI4 installation using the method of using rpi-imager + desktopify + dedoimedo approach and it works perfectly. Maybe its a bug?
Also maybe unrelated but each time I boot this image I get a Submit an Error Report window just after desktop shows completely.
Today I updated my "other" RPI4 and after the updates were applied now I dont have video here either. bummer. The same thing happens with Firefox and Chromium:
Sorry to inform that the reason it wasnt playing, in my case, was because of something trivial and not really trivial
It turns out that issue happens when the output device for the sound is left by default on a Raspberry Pi 4 which is the headphones output, instead of any of the two HDMI outputs.
For brevity of this post please see this other post for the details:
SOLVED!!!
