Ever since Yosemite and also with El Capitan the videos on Kelby One and Lynda.com will not play correctly. The video is out of sync with the audio and stutters like a bad DVD. The videos play fine in Firefox. I submitted the question to Kelby One and their only solution was to use a different browser. These videos played fine before Yosemite. Any clue? I am up to date on everything.
iMac, OS X El Capitan (10.11.1), 12 gig of ram
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data...
and confirm. Close the window. Then select
▹ System Preferences… ▹ Flash Player ▹ Advanced ▹ Delete All...
In the sheet that opens, check the box marked
Delete All Site Data and Settings
then click Delete Data. Close the preference pane. Test.
If you use a FireWire audio interface, disconnect it and test again. If you don't know what a FireWire audio interface is, you don't have one.
No difference. The video halts like a DVD that is bad. Plays fine on the iPAD,but that uses HTML5
