Unrecognized image encoding

[zfxw0206]

I am using aravis to drive Teledyne DALSA camera.

After running "ROS_NAMESPACE=cam1 rosrun camera_aravis camnode Teledyne DALSA-S1099729"
I got the error "[ERROR] [1455917134.838548734]: cv_bridge exception: 'Unrecognized image encoding [bayerrg8]'"

Does anybody know how to fix it?

Thank you!

which image encodeing from your camera? until to now this pkg only support image pixel format that in sensor_msgs::image_encodings.

@SwastikNandan Hi ! How did you solve this problem ?

[SwastikNandan]

@ghost sorry for the late reply! Are you facing this problem while converting streaming images using the cvbridge ?
