h264_image_transport

^{Forked from tilk/h264_image_transport.}

H264 subscription plugin for the ROS image transport.
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 sensor_msgs/CompressedImage message.

How to use

Build

• Create a workspace

  mkdir -p catkin_ws/src
  cd catkin_ws

• Clone the repo

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

• Build and source the workspace

  catkin build
  source devel/setup.bash

• The H264 plugin for the ROS image transport is now available.

Usage

• You can verify that the plugin is loaded correctly with :

  rosrun image_transport list_transports

  You should see :

    "image_transport/h264"
  - Provided by package: h264_image_transport
  - No publisher provided
  - Subscriber:
    This plugin decodes a h264 video stream.
  

• You can then decompress h264 messages like so :

  rosrun image_transport republish h264 in:=/interfacea/link0/image out:=/interfacea/link0/image/repub

  For details see the image transport republish doc.
