That means that the cDevice class has no method DeviceStillPicture(...). 
Looking at device.h you can see that there is a method 
StillPicture(...). Maybe you want to use this one.
In the file player.h there is a method cPlayer::DeviceStillPicture(...), 
which is a forwarder function to device->StillPicture(...).
