When loading a list of video files, firefox circular preloader crashes

[Qaaj]

Hi!

I'm trying to load a list of files, a couple of images and mostly videos (mp4 or webm). It's about 20 videos and loading in chrome is not a problem. There's a problem in firefox though, after loading about 17% of the assets, the preloader goes completely haywire (I'm using the circular loader example, just changed the files in the JSON file). It displays negative numbers like -5452592952 or so and then firefox crashes (windows + mac).

I thought this might be because my filesize in the JSON was too low and it caused an error in the calculations or something, so I made all video files 5% bigger in the JSON just to be sure but that didn't work. Any idea what might be causing this?

Here's how my JSON looks: http://pastebin.com/ta4KsXRA

Thanks a lot in advance!

Here's where it goes wrong:

_bytesLoaded = 9500

It seems that for webm in firefox, the value for this.buffered.end(0) is sometimes a big negative number.. hope that helps.

I managed to fix it by changing

bytesTmpLoaded = (size / this.duration) * this.buffered.end(0);

to

bytesTmpLoaded = size;

this gives it a less smooth loading progress but avoids the weird numbers and crashes. Maybe something to look into (webm + FF + buffered.end(0) don't play nice)

Hmm, first of all, I'd file a bug against Firefox. Can you give me bit more specifics as to how big the files are in total and such?
