Since two days, I can't play YouTube videos. They just hang forever. At some point I get a message like this
If playback doesn't begin shortly, try restarting your device.
I tried this in Chrome and in Firefox. Both hang forever. I can actually skip through the video and see different images, but I can't play the video.
I have the same issue with local files that I open with the Videos application.
What may I do to fix this?
I am using Ubuntu 18.04 since a year or so and never had this issue before.
