How to decompress compressed image topic?
Hello people,
I have a question on how to decompress image topics. I have a /D435/color/image_raw/compressed image and I am interested in decompressing it and get a new /D435/color/image_raw topic. My search led me to the image_transport package but probably I am not using it correctly. I am interested in using the nodes it has because I have 0 knowledge of cpp and I can not use the api. So far I've tried this and I got the following warning.
rosrun image_transport republish compressed in:=/D435/color/image_raw/compressed raw out:=/D435/color/image_raw
[ WARN] [1622914313.899141980]: [image_transport] It looks like you are trying to subscribe directly to a transport-specific image topic '/D435/color/image_raw/compressed', in which case you will likely get a connection error. Try subscribing to the base topic '/D435/color/image_raw' instead with parameter ~image_transport set to 'compressed' (on the command line, _image_transport:=compressed). See http://ros.org/wiki/image_transport for details.
Any idea how to cope with this or any other way to do it?? Thank you in advance.
