Stream247 — 24/7 VOD streamer and Twitch relay (to any RTMP/RTMPS)

Stream247 can either:

• Loop a public or unlisted YouTube playlist or single video as a 24/7 livestream, or
• Relay any Twitch channel (or direct .m3u8 HLS URL) to your target ingest.

All outputs go to virtually any RTMP/RTMPS ingest: YouTube Live, Twitch, Facebook Live, Owncast, Restream, custom Nginx-RTMP, and more. Stream247 automatically selects the best encoder available (NVENC/QSV/AMF with x264 fallback).

Features

• Input sources:
  • YouTube playlists (public or unlisted)
  • YouTube single videos
  • Twitch channels (auto-resolves to HLS via yt-dlp)
  • Direct HLS .m3u8 URLs (acts as a generic HLS relay)
• Destinations: any RTMP/RTMPS endpoint
  • Examples: YouTube Live, Twitch, Facebook Live, Owncast, Restream, custom RTMP servers
• Supports 480p, 720p, 1080p, 1440p & 4K output (configurable)
• Adjustable bitrate and buffer size; stream buffering presets (Low/Medium/High/Ultra) to smooth network hiccups
• Options to:
  • Overlay current title (YouTube) or Twitch channel name
  • Shuffle playlist order (for YouTube playlists)
  • Save source & key to config file
  • Test your RTMP endpoint with a 1s preflight push
• Smart encoder selection: NVENC > QSV > AMF > x264 automatically
• RTMP and RTMPS supported; optional RTMP "live mode" for Owncast compatibility
• Windows convenience: auto-downloads FFmpeg and yt-dlp next to the app if missing

Usage

1. Paste a Source URL:

• YouTube playlist (list=...), or
• YouTube video (watch?v=...), or
• Twitch channel (e.g., https://www.twitch.tv/<channel>), or
• Direct HLS .m3u8 URL

2. Enter your RTMP/RTMPS ingest URL for the destination (e.g., rtmp://a.rtmp.youtube.com/live2, rtmp://live.twitch.tv/app, rtmps://live-api-s.facebook.com:443/rtmp/, rtmp://<your-server>/live).
3. Enter your destination Stream Key.
4. Choose your desired quality and bitrate.
5. (Optional) Enable extras like overlays, shuffle (YouTube playlists only), or "RTMP live mode" (Owncast).
6. (Optional) Click Test RTMP to verify connectivity.
7. Click Start Stream to go live!

Example

Notes

• Destinations: Any platform that accepts RTMP or RTMPS should work. Check your platform’s recommended bitrates and resolutions.
• Input sources:
  • YouTube: playlists/videos should be public or unlisted so yt-dlp can fetch them.
  • Twitch: paste a channel URL and the app will resolve its HLS automatically; or paste a direct .m3u8 URL.
• Overlay behavior:
  • YouTube: shows "<Title> • " with smart truncation
  • Twitch: shows "Twitch • "
• Windows: If not found, the app can auto-download FFmpeg and yt-dlp next to the executable.
• Owncast: Enable the "RTMP live mode" toggle for improved compatibility.
• Networking: Ensure outbound traffic to your ingest host/port (commonly 1935 for RTMP or 443 for RTMPS) is allowed.
• Designed for 24/7 operation — great for music channels, replay loops, relays, or archives.

Linux AppImage build

AppImage builds are supported via the helper script in appimage/.

Requirements:

• python3 with venv support
• appimagetool in your PATH (from AppImageKit releases)
• Runtime dependencies on the host: ffmpeg and yt-dlp available in PATH

Build:

./appimage/build_appimage.sh

The output will be Stream247.AppImage in the repo root.

Current scope

Stream247 now operates as both a 24/7 VOD streamer (YouTube playlists or single videos) and a stream relay (Twitch channels or direct HLS) to your chosen RTMP/RTMPS destination. More input sources may be considered in the future.
