11.2 performance issues (heads up!)

Recommended Posts

Adobe just release 11.2 of the flash player that appears to really mess up the seek function on netstream objects. I didn't delve very far into the issue but I wrote a little test app to confirm the issue. I have attached the project to help.

 

The summary is that I tested seeking to each frame of a video in a loop and got the following results:

 

-----------------------------------------------------

flash version: MAC 10,3,183,18

-----------------------------------------------------

complete - ready to loop through seek on 1273 frames

starting seek through video at: 4614

ending seek through video at: 4617

total time: 3ms

starting seek through video at: 6907

ending seek through video at: 6910

total time: 3ms

starting seek through video at: 9134

ending seek through video at: 9137

total time: 3ms

starting seek through video at: 11349

ending seek through video at: 11353

Hope this helps.

I'm working on a loops based project and client sees about 1 sec.stop on it.
