Hi all!
I cannot use this type of data: sensor_msgs/CompressedImage. I've trasformed the originale image stream with the "image_transport" package, to send image over internet. Now i need to trasform this compressed image in a usable image (a sensor_msgs/Image or somethink like).
Any suggestions??
Thanks a lot!
SOLVED:
With instruction: cv::Mat matrix = cv::imdecode(cv::Mat(buffer_image_compressed),1)
it's possibile to use the compressed image in opencv!
If you're using ROS check out this answer: http://answers.ros.org/question/35183/compressed-image-to-image/
You would use this like:
rosrun image_transport republish compressed in:=/internet/image out:=/camera/image
Where the topic for your internet stream is:
/internet/image/compressed
Thank you @Chad Rockey . It was quite thoughtful of you to say that the internet stream image topic name. Very Useful!

Are you attempting to decompress the raw bytes outside of ROS or simply to subscribe to a compressed image stream using ROS on a remote machine?
I need to use image stream in ros. I hope to transform compressImage data in a CvMat :D or any opencv data format.
