rospy.wait_for_message change queue size
Hi,
I am grabbing images from a topic published by a camera plugin in gazebo. The problem is, that the camera topic has a queue size of 2 (according to rviz). So whenever I get an image it is the oldest of the two on the topic and not of interest.
The rospy.wait_for_message API has no parameter to change the queue size, or flush the queue. https://docs.ros.org/diamondback/api/...
Also for the camera plugin I haven't found a configuration parameter to change the queue size .. http://gazebosim.org/tutorials?tut=ro...
A workaround of course would be to grab an image 2 times from the topic and discarding the first message. But this isn't really elegant.
I guess it has to come out to change the queue size on the plugin side, so any hint is really appreciated.
