I installed Safari 10 on my Macbook and now any JW video is missing the Adaptive Bit Rate HD Icon. The old Safari 9.x worked fine and Google Chrome still works fine. Can anyone tell us how to accommodate the new Safari 10 browser?
Since HLS is natively supported in Safari, the player will not show the HD button in the control bar in that browser if the player is rendered in HTML5 because Safari itself does not allow for the manual switching of qualities in their native player. To workaround this, you could set the player to always render in Flash which is most likely what you are doing and this will show the HD button and allow users to switch qualities.
The issue you are having now is most likely because the update to Safari, version 10, now automatically blocks Flash and since Flash would be blocked, our player falls back on playing the HLS stream in HTML5, thus not giving users the ability to switch qualities via the HD button. The blocking of Flash can be overridden in Safari 10, via the steps on this article on Apple’s Support site, but there is no way for the player itself to force itself into Flash if it is blocked.
I hope this helps. Thank you.
