Auotplay not working on Safari, & can't even CLICK play either...

@John -

This was a known issue with the 'autostart' option in iOS. It will be fixed in 5.9.

Thanks @Pablo.

So, I just see that FIreFox (version 9, on Mac) is making the video not play either, and when clicked, opens the MP4 file in the URL/address bar, outside the context of the containing page.... doh! I think that's an entirely new behavior with Firefox?

And, for the Safari workaround, here's some code that I got working to turn on/off autostart for Safari:

function enable_autostart(){
var browser=navigator.appName;
var navindex=navigator.userAgent.indexOf('Safari');
var chromeindex = navigator.userAgent.indexOf('Chrome');
if ((navindex > 0 && chromeindex < 1 )|| browser=='Safari') {
//alert('safari=true');
return 'false';
} else {//alert('safari=false');
return 'true';}
}

That sounds like you may have disabled Flash in Firefox. The behavior you're describing occurs in Firefox when the player detects that the media can't be played in Flash or HTML5 mode, and reverts to a "download" mode (usually only used on older mobile devices).

@Pablo: That was it! Yes, I've been reading up more on video/html5 & such on your website, and LongTailVideo does have great expertise & responsiveness. Any time I have an issue, I find the answers here fast. Thanks so much!
