FLV player problem

I’m building a custom flv player using the FLVPlayback component.

I’m looking for a way to catch an event when the movie enters a new frame (in the flv and not on the timeline).

So I tried changing the playheadUpdateInterval of my player to a low rate of 0.25, but that causes the player to stop playing (for some unknown reason).

How can I catch an event on a FLV’s current frame playing?

Or maybe there’s a way to solve it with the update interval?

Thanks,
OML
