Subject: Re: Seek problem in rendering plugin
It sounds like you have a reentrancy problem. Where are you calling Seek()
from? Inside OnPacket? That is likely confusing the player's timeline or
some other internal mechanism. I know of one customer that called Stop()
on the player from his OnPacket() and this wreaked all sort of havoc. As a
general rule of thumb you are not supposed to call back into the player
when you receive a callback.
I suggest that you use the player's IRMAScheduler and schedule a callback
for 0ms. The player will call back into your renderer when it is safe for
you to do a seek.
Try implementing the IRMACallback interface on your renderer and inside
Func() call Seek() on the player. Then when you want to do a seek, query
the IRMAPlayer for IRMAScheduler and call RelativeEnter(this, 0) to
schedule a callback. It should call back into you almost immediately.
Also, be sure to store the handle it returns and set it to NULL in your
Func(). If your renderer is stopped or destroyed before you receive your
callback (not likely... but it never hurts to write clean code) you'll need
this handle so you can call RemoveCallback() on the scheduler.
