[pwc] Delay capturing?

[Björn Annighöfer]

Hi,

I am trying to to synchronize two webcams so that the delay between two 
images taken by the cams becomes as small as possible. From experiments 
I see that the delay of the two cams is far from beeing constant. So my 
idea was it to build feedback control loop that whenever the time 
difference gets to big I delay one cam a little bit, to get the ime 
difference smaller again.

So far I found no way to delay the capturing of cam just al little bit. 
I tryied just to skip a frame in one cam but that has no effect (I think 
because the camera internaly follows it's fixed rate).

Any ideas?

Thanks Björn
