So i try to "disable" this if-sentence .
//Currently use native support when available, e.g. Safari desktop
if (Hls.isSupported() && !mw.isDesktopSafari() && !mw.getConfig("disableHLSOnJs") && 1==2 ) {
var orig_supportsFlash = mw.supportsFlash;
mw.supportsFlash = function () {
But still no success.
Or did I think in the wrong Direction ?
