Flash freeze for 60 seconds in Chrome
Hi Guys,
I am working on some Adobe Flex (v. 4.5.0) application (it using a lot of
javascript also through ExternalInterface) and from some time we are
noticing freeze of these application for 60 seconds in Google Chrome with
default Flash Player plugin.
I spend some time to optimize some logic in the application, but it didn't
help.
I'm wondering whether this could be problem with default Chrome flash
player.
If you guys had any similar problems - some information on that would be
precious.

I would like to summarize my freeze problem in Chrome just for those of you
witch could have same problem.
I had two places witch caused freeze of whole application in Google Chrome
In both cases I had javascript function with lots of logic inside it. I have
called them from Flex app by ExternalInterface.
In first case I didn't recognize witch line of code in js function caused
freeze, as for the second case it was JQuery function.
My workaround for this problem was add timeout for logic inside js function:
ExternalInterface.call("myJSFunction"); - stopped in this place caused
freeze only in Google Chrome
function myJSFunction() {
setTimeout(function(){
//some logic caused freeze
}, 50);
}

Alex,
I have found yesterday that one of JQuery javascript function witch we are
using caused these freeze - app just stuck on ExternalInterface. I did some
workaround, tests passed.
Thanks,

My version of Safari claims to have JavaScript profiling. Haven't tried
it, but maybe it would help?

It didn't help Om - I didn't see anything when this option was On. Our
testers had old Google Chrome v. 32 and pepper Flash Player 12 and had
freeze in some other javascript function.
I did add setTimeout in these function and it help reduce a bit these
freeze, but still this is not a solution.
I am wondering what is happening in the ExternalInterface class during these
freeze.

Try setting
ExternalInterface.marshallExceptions = true;
before making the ExternalInterface call. Also enclose the call in a
try...catch. If something is going wrong on the JS side, you should be
able to catch it with this setup.
Thanks,
Om

I have found that flash is freezing probably on ExternalInterface.call. -
It's just stuck for 60 seconds or less.

If it happens in one player but not the other it's a player problem :)

@João you mean just use regular flash player ? - This doesn't occur so far in
the regular flash player.
@Avi that's why I wrote on the dev list, because from that point where I'm
now I'm still not sure whether this is Flash Player problem.

You could try to install the regular flash player (non debug) in chrome and
disable the default bundled with it.

For my day to day browsing, I try to use the debug player in chrome,
because I find it's performance is much better. There seems to be some
restrictions with the Pepper Flash api on what resources it can access vs
NPAPI. It's worth the time to isolate if it's a flash player version
problem or a code problem on your side.
