web_video_server

HTTP Streaming of ROS Image Topics in Multiple Formats

This node combines the capabilities of ros_web_video and mjpeg_server into a single node.

For full documentation, see the ROS wiki.

Doxygen files can be found on the ROS wiki. mjpegcanvasjs can be used to display a MJPEG stream from the ROS web_video_server

This project is released as part of the Robot Web Tools effort.
