Synopsis

  • TCP port 1935 is the default port for RTMP (Real-Time Messaging Protocol) live streaming.
  • Adobe Flash Media Server/Adobe Media Server and Wowza Streaming Engine listen on 1935 for RTMP publish and playback.
  • Other servers using 1935 for RTMP include Nginx with the RTMP module, Red5/Red5 Pro, and Ant Media Server.
  • Major platforms accept RTMP ingest on 1935, including Twitch, YouTube Live, Facebook Live, Vimeo Live, and Restream.io.
  • Broadcasters commonly push to 1935 using OBS Studio, XSplit, Wirecast, vMix, and hardware encoders like Teradek VidiU, LiveU units, AJA HELO, and Magewell Ultra Stream.
  • Many streaming services and CDNs (e.g., Akamai, Wowza Cloud, Brightcove Live) provide RTMP ingest on 1935.
  • Security: RTMP on 1935 is typically unencrypted, and exposed RTMP services (e.g., Adobe Media Server, Red5, Wowza) have had RCE/DoS CVEs; open 1935 endpoints are often probed and abused to steal or restream live feeds.
