I'm a complete noob on this subject, so I am hoping that someone can educate me. 98% of the time, I have no problems, whatsoever, watching YouTube vids. Periodically, I will come across a vid that simply will not play, accompanied by a message indicating that my browser does not support any of the available formats. A link accompanies this message, which probes the browser to determine which codecs are supported. When I experience this issue, the link says that H.264 and MSE & H.264 are not supported.
Last night I came across this problem. A specific YouTube vid refused to play on Vivaldi and it also refused to play on Opera. It played just fine on Chrome and Firefox, however. As usual, the probe said that I had no H.264 support. I looked in the Software Center and I have the x264 codec installed, so I'm not sure what to make of this.
I had a look at the Vivaldi forum and lots of people are complaining that they have no video playback and the solution is to install the H.264 codec from this site: https://gist.github.com/ruario/bec42d156d30affef655
So, this morning, the vid that would not play is now playing just fine on both Vivaldi and on Opera!!! In the meanwhile, I have not updated my distro, rebooted my machine, restarted Vivaldi, installed/removed any codecs, or done anything else, which would seemingly affect this problem. The response that I received on the Vivaldi forum is that I need to install the H.264 codec mentioned above and that if that doesn't sort my problem, the vid must be wrapped in DRM. DRM? Why would Gamer's Nexus https://www.youtube.com/channel/UChIs72 ... 6d6FhwGGHA be wrapping their vids in DRM?!?!?!
Does anyone have any insights, or suggestions that may may help me to better understand why this is happening?
BTW - I do not have Flash installed.
