Bug 45726 – Crash when binding to <audio> 'play' event

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: Media

[Alexander Kahn]

On the page I'm working on, when I bind a function the the play event of an audio element, the browser crashes. I'm binding to the event using jQuery with the code below:

        $('audio').bind('play', function() {
          alert('started playing');
        });

Attached is the page. It's simple but not all the way reduced.

Maybe this has to do with the fact that the MP3 file I'm playing with my audio tag is a stream as opposed to a file. But that's just a guess.

I should add that since this page makes an AJAX request, it needs to be downloaded and run locally, or else the AJAX request fails due to cross domain restrictions.

I'm adding a reduced test page. The page indicates that the crash occurs when binding using jQuery, but not when simply using addEventListener.

It seems that part of the problem is, indeed, the fact that the media is an audio stream as opposed to a discrete file. Change the audio src to http://dl.dropbox.com/u/2104764/test.mp3 (an actual MP3 file) and the browser no longer crashes.

This seesm to be a crash in QuickTime itself?  The Apple folks are needed here.

It doesn't crash for me.

This works for me on 10.6.4 with both Safari 5 and TOT WebKit. 

From the crash log I wonder if this was a CFNetwork but that was fixed in 10.6.4?

Are you able to reproduce this with 10.6.4?
