RTMP and RTSP do different jobs. RTMP commonly sends an encoder’s live feed to a streaming server over a persistent TCP connection. RTSP sets up and controls a media session; the audio and video are commonly carried separately using RTP. For a typical streaming workflow, RTMP is a common choice for encoder-to-platform ingest, while RTSP/RTP is common for bringing an IP-camera feed into a media server. The right choice depends on what both endpoints support.
What is the difference between RTMP and RTSP?
| Question | RTMP | RTSP with RTP |
|---|---|---|
| Common role | Contribution or ingest: an encoder sends a feed to a server or streaming service. | Session setup and control, commonly for camera or media-server sessions. |
| How media travels | Audio and video are commonly carried within RTMP over a persistent TCP connection. | RTSP controls the session; RTP commonly carries the media separately. Implementations can vary. |
| Common source | Software or hardware encoder, such as one configured to send to a platform’s ingest URL. | An IP camera or surveillance source that supports RTSP/RTP. |
| Viewer playback | A media server can ingest either workflow and deliver to viewers using a separate protocol, such as HLS, MPEG-DASH or WebRTC, depending on its configuration and supported clients. | |
RTSP is not simply another name for a stream carrying video. RFC 2326, the IETF’s RTSP 1.0 specification, says: “It does not typically deliver the continuous media.” RTSP 2.0 is specified in RFC 7826 and is not generally backwards-compatible with RTSP 1.0 beyond basic version negotiation, so a device labelled “RTSP” should not be assumed to implement version 2.0. Many deployed camera products and guides still describe RTSP 1.0-era behavior. RFC 2326 · RFC 7826
Which should you use for live streaming?
Use RTMP when an encoder is sending to an ingest endpoint
If your encoder—such as a software or hardware production tool—asks for a server URL and stream key, and the destination provides an RTMP ingest endpoint, RTMP is the straightforward match. Follow the destination’s current ingest requirements; prefer RTMPS, which protects RTMP contribution with TLS, when the platform supports it. This is a common workflow, not a universal rule for every service. Wowza’s protocol comparison
Use RTSP/RTP when pulling from a compatible IP camera
If a camera exposes an RTSP URL and your media server accepts RTSP/RTP, use that workflow to ingest the camera feed. Check the exact camera model’s documentation for URL syntax, authentication, supported codecs and transport options; an RTSP label alone does not guarantee compatibility. Wowza’s IP-camera guidance

Choose viewer delivery separately
Ingest and playback are separate decisions. A server can receive an RTMP or RTSP/RTP source and then provide a viewer-oriented output such as HLS, MPEG-DASH or WebRTC, where supported. Do not assume that an RTMP or RTSP source URL is also the right URL for a browser, phone app or OTT player. Wowza Streaming Engine technical specifications
What to check before connecting a camera or encoder
- Endpoint support: confirm that the source can publish or expose the protocol the server accepts. For cameras, verify the exact model and firmware documentation.
- URL and credentials: camera stream paths and authentication requirements can be manufacturer-specific. Keep credentials private and avoid exposing camera endpoints directly to the public internet.
- Codecs: confirm that the receiving server supports the camera’s or encoder’s audio and video codecs. Protocol compatibility does not by itself mean codec compatibility.
- Transport and network policy: RTMP commonly uses TCP. RTSP control and RTP media have distinct roles; RTP may use UDP or be interleaved over TCP, depending on implementation. Firewalls, NAT and blocked UDP ports can prevent an otherwise valid session from working.
- Security: check protection for both control and media. RTMPS uses TLS for RTMP contribution when supported. RTSPS protects the RTSP control connection, but does not by itself encrypt RTP media; assess media protection separately, such as SRTP where supported. Wowza’s security guidance
Ports and firewall behavior
Port numbers are configuration defaults, not universal protocol requirements. Wowza documents TCP 1935 as its RTMP default and TCP 554 as its RTSP default. An RTSP deployment may also need media ports for RTP, particularly when using UDP; the actual ports and transport behavior depend on the server and endpoints.

If a camera works on the local network but not through a firewall or NAT, inspect the selected RTP transport and the network rules for both control and media traffic. Interleaved RTP over TCP may work where UDP is blocked, but both endpoints must support that mode. Opening ports broadly is not a substitute for securing the camera and server.
Troubleshooting RTMP and RTSP connections
| Symptom | Likely checks and fixes |
|---|---|
| Encoder cannot connect to the ingest server | Check that the server URL and stream key match the destination’s current settings, the selected protocol is accepted, and the relevant outbound TCP connection is allowed. If available, try the destination’s RTMPS endpoint. |
| Camera URL is rejected or returns no stream | Recheck the exact model’s RTSP path, username and password, codec support, and whether the server accepts the camera’s RTSP/RTP behavior. Do not assume one manufacturer’s URL syntax works for another. |
| RTSP control connects but there is no picture or audio | Check RTP media transport and ports separately from the RTSP control connection. Confirm the selected UDP or TCP-interleaved mode is supported at both ends, and verify the media codecs. |
| Camera works on LAN but fails across NAT or a firewall | Review firewall rules and NAT handling for the media path, not only the RTSP connection. Where UDP is blocked, test interleaved RTP over TCP if both endpoints support it. |
| Source connects but viewers cannot play it | Check the server’s configured output protocol and the player’s support. Ingest success does not establish browser or mobile playback compatibility; configure a suitable viewer delivery protocol. |
| Stream works but is not protected as expected | Check encryption separately for control and media. RTMPS/TLS protects the RTMP connection; RTSPS alone does not protect RTP media. |
