Hello everyone, i am running uvc_camera package and there are several released topics such as:

/camera_info
/image_raw
/image_raw/compressed
/image_raw/compressed/parameter_descriptions
/image_raw/compressed/parameter_updates
/image_raw/compressedDepth
/image_raw/compressedDepth/parameter_descriptions
/image_raw/compressedDepth/parameter_updates
/image_raw/theora
/image_raw/theora/parameter_descriptions
/image_raw/theora/parameter_updates

My idea is creating a subscriber to subscribe the topic /image_raw above.

How can i do that ?

Thanks in advance!
