Large QT video's and QT transition errors

Post by Simon » Fri Aug 03, 2007 7:14 pm

Hi,
I'm displaying QT video's (.mov Sorenson3) of about 200 MB each, not doing anything fancy with them, just Play with option to Exit back to the main menu. From the main menu I use QT transitions to dissolve to the next selected video or next page (cards). With small video's I can do this all day long and not have any problems, with the large video's the app shuts down with a "send error report". This happens right after the transition or at the start of the transition.
Using dontUseQTEffects does solve the problem so I guess QT is the problem.
My question is, is this a QT memory problem? Is there a way to "Destroy" the QT in memory?

Thanks for any help,
Simon

Hi Simon,

Do you still have the stack that is causing this crash? It does sound like it might be a QT bug, but if we can reproduce the crash on our test systems then we should be able to pinpoint the exact cause of the problem.

Hi Oliver,
Yes, I still have the stack. I have to check the NDA status of the assets but if it clears who do I send it to?
It's a nice error that repeats on a regular basis.

Thanks,
Simon

I did leave one very important fact:
The QT .mov data rate is 1.4 MB/sec.

So it's not just a 200 MB file, I expect the data rate has something to do with it as well.

Thanks,
Simon
