Trigger camera via MAVROS

Hello,
I use a Pixhawk with Arducopter 3.3 and I want to trigger the camera with mavros.
I try with
rosservice call /mavros/cmd/trigger_control 1 0
but it answer :
success: False
result: 3
And nothing in mavros terminal:
The link is working as when I call :
rosrun mavros mavsafety arm
In terminal:
Request failed. Check mavros logs
And in mavros terminal:
[ERROR] [1476375492.460409636]: FCU: PreArm: inconsistent compasses

Is /mavros/cmd/trigger_control supposed to work with ArduCopter or only with PX4 firmware ?
How to trigger camera via mavros ? With RC_Override ?

Thanks for your help
