Publish

Send a broadcast to the MoQ CDN from OBS, FFmpeg, a WHIP or SRT encoder, or a native MoQ client.

Every protocol lands as the same MoQ broadcast, so viewers, recordings, and usage do not care how it arrived. The dashboard's Guides page fills in the URLs below for your project and broadcast.

Before you start

You need a project id and a publish token for the broadcast. The quickstart creates both, and Tokens covers scoping one. Skip the token if public access already lets anyone publish the path.

In the URLs below, replace <project> with the project id, <broadcast> with a name of your choice, and <jwt> with the token. Drop ?jwt=<jwt> (or SRT's ,jwt=<jwt>) for a public path. End the name in .hang so the dashboard can preview it and recordings line up.

Protocol	Use it for	Video	Audio
RTMPS	OBS, FFmpeg, and most hardware encoders	H.264, H.265, VP9, AV1	AAC, MP3, Opus
SRT	Contribution encoders on lossy links	H.264, H.265	AAC, Opus
WHIP	Browsers and WebRTC publishers	H.264, VP8, VP9	Opus
MoQ	The lowest latency, with no conversion	What the client sends	What the client sends

RTMPS

rtmps://cdn.moq.pro:1935/<project>/<broadcast>.hang?jwt=<jwt>

RTMPS uses port 1935; port 443 is QUIC and fails the RTMP handshake. A broadcast name cannot contain ?. Upstream's RTMP page covers the bridge.

OBS

In Settings → Stream, set Service to Custom, paste the URL as the Server, and leave Stream Key empty: the token rides in the URL. If an encoder insists on a stream key, drop ?jwt=<jwt> from the Server and use the token as the stream key instead.

FFmpeg

Set RTMP_URL to the URL above. This publishes a test pattern with a tone. Replace the two lavfi inputs with your source:

ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=30 -f lavfi -i sine=frequency=440 \
  -c:v libx264 -preset veryfast -tune zerolatency -g 60 -pix_fmt yuv420p \
  -c:a aac -f flv "$RTMP_URL"

Quote the URL: an unquoted ? or & is shell syntax.

SRT

srt://cdn.moq.pro:877?streamid=#!::r=<project>/<broadcast>.hang,jwt=<jwt>

SRT has no path, so the broadcast and token ride in the streamid, as upstream's SRT page describes. A broadcast name cannot contain ,. The handshake sends the token in the clear, so avoid SRT on networks you do not trust.

To raise the receive buffer above its 200 ms floor, add latency before streamid. FFmpeg and OBS read it in microseconds (latency=500000&streamid=... for 500 ms); GStreamer reads milliseconds.

WHIP

https://cdn.moq.pro/whip/<project>/<broadcast>.hang?jwt=<jwt>

Paste it into any WHIP publisher. WebRTC carries no AAC, so send Opus audio. Upstream's WebRTC page covers the bridge.

MoQ

Native MoQ clients publish straight to the relay with no conversion. Connect to https://cdn.moq.pro/<project>?jwt=<jwt> and publish <broadcast>.hang:

• The moq CLI pipes FFmpeg's output in, as the quickstart shows.
• The OBS plugin adds a MoQ dock to OBS 32 or newer. Paste the URL without the token as Relay URL, the token as Publish token, and the name as Broadcast name, then Go Live.
• The GStreamer plugin publishes with moqsink.
• The <moq-publish> element publishes a camera or screen from a browser.

doc.moq.dev covers each client, the media formats, and the protocol.

While the encoder runs, the project's Broadcasts page lists the broadcast with a live preview. To watch it elsewhere, see Embed playback.
