@elizaos/plugin-streaming

Unified RTMP live streaming for Eliza agents. Supports Twitch, YouTube Live, X (Twitter), pump.fun, and custom or named RTMP ingest URLs.

What it does

• Adds a STREAM agent action so the agent can start/stop streams and check live status in response to natural-language requests ("go live on Twitch", "stop the YouTube stream", "is the X stream live?").
• Manages a local FFmpeg pipeline: screen/window capture, audio mixing, RTMP push.
• Supports Eliza Cloud relay mode: the cloud fans one inbound stream to N platform destinations using stored credentials.
• Provides a streamStatus context provider so the agent always knows which streams are live.
• Handles TTS-to-stream audio: agent speech is generated and piped directly into FFmpeg's audio track.

Capabilities added

Capability	Details
STREAM action	start, stop, status for twitch / youtube / x / pumpfun
streamStatus provider	Per-turn JSON snapshot of all platform stream states
Video capture	pipe (desktop UI), avfoundation (macOS), x11grab (Linux/Xvfb), file (headless browser), testsrc
Audio sources	silent, system, microphone, tts (ElevenLabs / OpenAI / Edge / local inference), audio file
Overlay layouts	Per-destination JSON widget layout; seeded from plugin defaults on first start
Stream settings	Visual settings (theme, avatarIndex, voice) persisted in data/stream/
Cloud relay	Push to Eliza Cloud ingest; cloud relays to platform RTMP endpoints

Requirements

• FFmpeg must be installed and on PATH. The plugin throws with install instructions if not found.
  • macOS: brew install ffmpeg
  • Linux: sudo apt install ffmpeg
• For TTS audio on streams: ElevenLabs, OpenAI, or Edge TTS API credentials (or a local inference model).
• For Eliza Cloud relay: ELIZAOS_CLOUD_API_KEY and cloud connection.

Enabling the plugin

The plugin activates automatically when any streaming destination is configured. Add to your agent config under the streaming key:

{
  "streaming": {
    "twitch": { "streamKey": "live_..." },
    "youtube": { "streamKey": "xxxx-xxxx-xxxx-xxxx" },
    "customRtmp": { "rtmpUrl": "rtmp://ingest.example.com/live", "rtmpKey": "my-key" },
    "rtmpSources": [
      { "id": "my-server", "name": "My Server", "rtmpUrl": "rtmp://...", "rtmpKey": "..." }
    ]
  }
}

Or via environment variables (all optional; any one enables the plugin):

Env var	Purpose
TWITCH_STREAM_KEY	Twitch RTMP stream key
YOUTUBE_STREAM_KEY	YouTube Live stream key
YOUTUBE_RTMP_URL	Override YouTube ingest URL
X_STREAM_KEY	X (Twitter) stream key
X_RTMP_URL	X RTMP ingest URL
PUMPFUN_STREAM_KEY	pump.fun stream key
PUMPFUN_RTMP_URL	pump.fun RTMP ingest URL
CUSTOM_RTMP_URL	Custom ingest URL
CUSTOM_RTMP_KEY	Custom stream key

Cloud relay vs. direct push

Set <PLATFORM>_STREAMING_BACKEND to control backend selection:

• direct — push to the platform's RTMP ingest using a local stream key (default when a key is set).
• cloud — request a per-session relay from Eliza Cloud; requires ELIZAOS_CLOUD_API_KEY.
• auto (default) — picks cloud when Eliza Cloud is connected and no local key is set; otherwise direct.

Stream key setup

Stream keys come from each platform's studio or dashboard — there is no OAuth in this package.

• Twitch: https://dashboard.twitch.tv/u/YOUR_USERNAME/settings/stream
• YouTube: https://studio.youtube.com → Go Live → Stream settings
• X (Twitter): https://studio.twitter.com → Go Live
• pump.fun: platform stream dashboard

Preset destination factories

import {
  createTwitchDestination,
  createYoutubeDestination,
  createXStreamDestination,
  createPumpfunDestination,
  createCustomRtmpDestination,
  createNamedRtmpDestination,
} from "@elizaos/plugin-streaming";

Pass a factory result to the streaming pipeline's destination map when constructing StreamRouteState.

Default export

import streamingPlugin from "@elizaos/plugin-streaming";
// or
import { streamingPlugin } from "@elizaos/plugin-streaming";

streamingPlugin is the Plugin object to register with an elizaOS agent runtime.
