Why won't YouTube play HTML5 video since I upgr...

Since I updated to Sierra, the new Safari won't play videos from YouTube, saying "Your browser does not currently recognize any of the supported video formats available". I didn't have this problem before upgrading.

Ok, after a bit of research I have found an answer for this that works for me.

It turns out that I had the "Click to Flash" plugin enabled in Safari Extensions.

If you have this plugin installed just disable it and the YouTube videos will load in the HTML5 player again.

I'm guessing the "Click to Flash" plugin needs an update to function correctly with Safari 10.

Hello,

It is just the video format incompatibility issue, with a video converter, you can easily solved this problem. And i have been using Doremisoft easy HD video converter from https://itunes.apple.com/jm/app/easy-hd-video-converter/id488066888?mt=12

to do the converting job, and it is great. You can have try. By the way, have a nice day.

We really should not have to run video conversion software just to view YouTube videos.

Something has changed with the latest version of Safari regarding the way it plays HTML5 videos.

It would be nice to know how to fix this without downloading the video and running video conversion software on the file.

If you have the extension "ClickToFlash" installed, uninstall it.

Indeed Click to Flash does not work in Safari 10. The author has stated that due to Apple changes he will not be able to fix this so effectively Click to Flash is dead and discontinued.

Note: The new default behaviour for Safari is not to enable flash on web sites. You have to explicitly enable it per website in Safari Preferences. Since most of YouTube content is available in HTML5 you do not need to enable Flash for YouTube, you would need to enable Flash for BBC iPlayer though as one example.

Worked like a charm.  Should have realized that before....... Thanks
