LabelsReal-time Transport Protocol media data (RTP) (RFC 3551 RFC 4571)

Synopsis

  • UDP 5004 is the IANA-registered port for Real-time Transport Protocol (RTP) media data.
  • VLC media player’s RTP/UDP streaming uses port 5004 for the media stream (with RTCP typically on 5005).
  • FFmpeg commonly sends or receives RTP on 5004 in its RTP workflows and sample configurations.
  • GStreamer RTP pipelines frequently bind udpsink/udpsrc to port 5004 for media transport.
  • Live555-based RTSP stacks (e.g., openRTSP, live555MediaServer) use 5004 for multicast RTP sessions in examples and deployments.
  • Wowza Streaming Engine can deliver RTP/UDP on 5004 for broadcast/OTT workflows.
  • IP cameras and NVRs (e.g., Axis, Hikvision) are often configured to multicast their RTP video streams to 239.x.x.x:5004.
  • Security note: exposed RTP on 5004 has been abused for eavesdropping on camera/VoIP streams when encryption (SRTP) is not used.
