How to deactivate those topics which are not needed? #239

Closed Shibaditya99 closed 2 years ago

Shibaditya99 commented 2 years ago

I've successfully transfered the video stream one to another process with it. But in the ros topic list I can see there's several topics are activate like "compressed", "theora" etc. which I don't need. So how to deactivate those topics? I only need the raw data. Thank you so much.

I actually came across this the last few days, too. It seems like there was the option to deactivate plugins by adding them to the parameter disable_pub_plugins. However, with the current ros2 branch, I'm slightly confused about what happened with reading the parameter.

With #84 the line reading the parameter was commented out, but the blacklist remained. From how I understand the current code, the blacklist is always empty, no matter what value is set for the parameter. This line (https://github.com/ros-perception/image_common/blob/ros2/image_transport/src/publisher.cpp#L115) should actually be used, shouldn't it?
