Internet Explorer ActiveX detection and minimum Flash version


Hullo,

While testing the player we discovered an issue with Flash version detection due to the change in how IE11 exposes ActiveX to JS.

https://msdn.microsoft.com/en-us/library/ie/dn423948(v=vs.85).aspx
As of IE11 ¨typeof window.ActiveXObject¨ will always be undefined, so we changed the check to ¨"undefined"!==typeof window.ActiveXObject||("ActiveXObject" in window)¨

Furthermore, Flash version 10 is not really the minimum supported. The lowest version we could load the SWF with was 10.1.53.64. And the lowest version that supported HLS in Flash 10.1.82.76

So you might consider updating Flash version checks, though this probably affects a very small subset of users.

Testing environment:
Internet Explorer 11 on Windows 7
Internet Explorer 8 on Windows XP
Flash ActiveX plugin
JW Player 6.11.4923 Enterprise
