What it does

  • Rbfimagesrc subscribes to ROS 2 image topics, accepting raw Image and CompressedImage messages and converting formats automatically.
  • Rbfimagesink publishes to ROS 2 topics, choosing raw or compressed messages based on the incoming caps.
  • Timestamps are carried through pipelines via GstReferenceTimestampMeta so time information survives processing.
  • Both elements offer configurable QoS settings for reliability, durability and history depth.
  • The sink can publish camera calibration info from a file or package URL and expose a set_camera_info service.
  • Example pipelines include displaying a topic, streaming test video, publishing JPEG streams and streaming a V4L2 camera.
