Documentation
image_transport_plugins contains plugins to image_transport for sending sensor_msgs/Image topics in compressed representations. Its contents include:
compressed_image_transport is a plugin providing JPEG and PNG compression of still images. Most useful for low-framerate/discontinuous image sources (e.g. a polled camera), or when lossless compression (PNG) is required.
theora_image_transport is a plugin that compressed image topics using the Theora video codec. Useful for live video feeds.
libtheora (http://www.theora.org) is the open source Theora video codec.
These transports will only be available if the plugins are built on your system! On Ubuntu, they are included in the ros-<distro>-image-transport-plugins deb for each distribution. If building from source, you must explicitly build the image_transport_plugins stack.
Stability
As of Diamondback, this stack has a stable ROS API.
