Re: [Java-player-users] camera problems

[Radu B. R. <ru...@cs...>]

I had the same problem while playing with the CMUcam2 some months ago. I 
had to go into the player driver and modify a lot of things in order to 
get stuff to work.

What player driver are you using? I have a hunch that is a player issue 
(since Javaclient worked just fine with the CMUcam2), but we could check 
Javaclient as well. :)

Cheers,
Radu.
