Hi, When I run image_transport to decompress color images coming from openni I receive this error: >rosrun image_transport republish compressed in:=/camera/rgb/image_color/compressed terminate called after throwing an instance of 'image_transport::TransportLoadException' what(): Unable to load plugin for transport 'compressed', error string: According to the loaded plugin descriptions the class image_transport/compressed_sub with base class type image_transport::SubscriberPlugin does not exist. Declared types are compressed_sub image_transport/raw_sub theora_sub I also see that the "compressed" plugin is already installed: >rosrun image_transport list_transports Declared transports: compressed image_transport/raw theora (*): Not available. Try 'rosmake theora_image_transport'. Details: ---------- "compressed" - Provided by package: compressed_image_transport - Publisher: This plugin publishes a CompressedImage using either JPEG or PNG compression. - Subscriber: This plugin decompressed a CompressedImage topic. Does any one know why the decompression does not work? I am using Diamondback btw... Thanks, Akin
