Mobile Safari Crash

I have a JWPlayer embedded in an AngularJS view and it's pointed at a video on a remote server to play. I'm seeing an issue on iPad when using Mobile Safari. We have navigation buttons on our page that allow us to move thru a set of pages. If I hit a button to navigate away from the page before the JWPlayer video loads, Safari crashes hard.

I don't see the issue when I browse from my Mac and I don't see the issue using Chrome on the iPad, just Safari on iPad.

Just wondering if anyone has seen anything like this before? And any ideas of where to start looking? Thanks.

Do you have a link we can look at?

Hey Ethan,

Sorry, I don't have a public link... maybe I can put together a little example that I can put on an external server. One thing we noticed tonight is that we get the same crash in Chrome on iPad also.

If I turn off the source, so it's not trying to load a video, then I don't see the crash. So it seems that the crash happens when the jwplayer is actively loading a video and we navigate away from the page. If we delay like 5 seconds, then navigate away, it works fine.

Hi Ethan, I work with Russell. Is there a way we can get a copy of 6.9 RC and see if that changes things?

Hi Ethan, Is a 6.9 zip downloadable for a self-hosting situation? When I click on download link my account I still get 6.8.

Not yet, but you can get the 3 files separately from:

http://p.jwpcdn.com/6/9/jwplayer.js
http://p.jwpcdn.com/6/9/jwplayer.html5.js

Thanks Ethan, gave 6.9 a try, but it didn't fix our crash.

Np.

I really need to be able to see something in order to debug properly.
