Is it not possible for RViz to subscribe to compressed image topics? I'm using the raspicam_node to publish a compressed image stream from a camera on a raspberry pi:
https://github.com/fpasteau/raspicam_...
I can display in RViz fine if I republish the topic locally on my desktop, but it would be nice to have RViz subscribe directly. Is that possible?
1) Published the compressed image on /your_topic_here/compressed
2) Add an Image in rviz. Under Image Topic fill in /your_topic_here (without the compressed)
3) Select compressed from the dropdown.
I believe compressed does not appear in the dropdown unless the compressed sub-topic is available.

You may be able to make rviz subscribe to the compressed image by changing the
Transport Hintproperty of the Image View or Camera View.I also thought that, but the only hint listed is 'raw'; I can't change it to something else.
Typing
compressedin the Transport Hint might work.Would be nice, but it's only a dropdown box; can't type anything in it.
Can someone please complete the solution. How can we add compressed to the transport hint?
