Re: [Playerstage-users] single player driver instead of libplayerdriver

[Vinh <arb...@go...>]

Ok, I found the problem. My CMVision_Register is not called at all.
Maybe the player_driver_init is actually getting the implementation
from an integrated driver (since I derived mine from the cmvision
driver). Changing the class name worked for me now. Thanks everyone
for helping!!
