h264_image_transport

H264 plugin for the ROS image transport. Forked from tilk/h264_image_transport.

There are two packages :

  • h264_image_transport
    • Contains a H264 subscription plugin for the ROS image transport only,
  • h264_image_transport_msgs
    • Contains messages for the plugins above.

This repo has been created to be used in pair with the nvidia_gmsl_driver_ros but can be used to decode any h264 packets published with the correct message.

How to use

  • Create a workspace 
    mkdir -p catkin_ws/src
cd catkin_ws

    git clone git@github.com:UT-ADL/h264_image_transport.git ./src
