RTMP

LiveForge includes a full RTMP implementation supporting both ingest (publish) and playback (subscribe).

Configuration

rtmp:
  enabled: true
  listen: ":1935"
  chunk_size: 4096
  # tls: true          # Optional: override global TLS setting

Field	Type	Default	Description
enabled	bool	true	Enable/disable the RTMP module
listen	string	":1935"	TCP listen address
chunk_size	int	4096	RTMP chunk size in bytes
tls	*bool	nil	Per-module TLS override (see Server & TLS)

When TLS is enabled, the module serves RTMPS.

Supported Commands

• connect -- Client connection with app name
• createStream -- Create a new RTMP stream
• publish -- Begin publishing to a stream key
• play -- Begin subscribing to a stream key
• deleteStream -- Close a stream
• FCPublish / FCUnpublish -- Flash Communication publish commands
• releaseStream -- Release a stream key

Publish Examples

OBS Studio

1. Settings > Stream
2. Service: Custom
3. Server: rtmp://your-server:1935/live
4. Stream Key: stream1

FFmpeg

ffmpeg -re -i input.mp4 -c copy -f flv rtmp://localhost:1935/live/stream1

With Authentication Token

When JWT auth is enabled, pass the token as a query parameter:

ffmpeg -re -i input.mp4 -c copy -f flv "rtmp://localhost:1935/live/stream1?token=eyJhbGciOi..."

In OBS, append the token to the stream key:

stream1?token=eyJhbGciOi...

Play Examples

FFplay

ffplay rtmp://localhost:1935/live/stream1

VLC

Open Network Stream: rtmp://localhost:1935/live/stream1

Use Cases

• Primary ingest point for OBS, FFmpeg, GStreamer, and other RTMP encoders
• Low-latency distribution to RTMP-compatible players and CDNs
• Protocol bridging -- publish via RTMP and play via HLS, DASH, WebRTC, or any other protocol
