Multistreaming maximizes your audience reach by broadcasting to multiple platforms at once. A VPS handles the heavy lifting so your gaming PC stays focused on gameplay.
Why Multistream from a VPS?
Streaming to one platform from home uses 6-10 Mbps upload. Three platforms: 18-30 Mbps. Most home connections can't sustain this reliably.
With a VPS:
- You stream once to your VPS
- The VPS restreams to multiple platforms
- Your home upload: 6-10 Mbps (single stream)
- VPS handles 3+ outbound streams with its datacenter bandwidth
Architecture
Your PC → (single stream) → VPS → Twitch
→ YouTube
→ Kick
Nginx-RTMP Setup
Install
sudo apt install nginx libnginx-mod-rtmp
Configure /etc/nginx/nginx.conf
rtmp {
server {
listen 1935;
chunk_size 4096;
application live {
live on;
record off;
# Restream to Twitch
push rtmp://live.twitch.tv/app/TWITCH_STREAM_KEY;
# Restream to YouTube
push rtmp://a.rtmp.youtube.com/live2/YOUTUBE_STREAM_KEY;
# Restream to Kick (via RTMP ingest)
push rtmp://kick-ingest.example/live/KICK_STREAM_KEY;
}
}
}
Start
sudo systemctl restart nginx
OBS Configuration
In OBS, set your stream target:
- Server:
rtmp://your-vps-ip/live - Stream Key: any key you want (it's your private server)
You stream once to your VPS, and Nginx pushes to all platforms.
FFmpeg Alternative
For more control, use FFmpeg directly:
# Read from Nginx RTMP and push to platforms
ffmpeg -i rtmp://localhost/live/stream \
-c copy -f flv rtmp://live.twitch.tv/app/TWITCH_KEY \
-c copy -f flv rtmp://a.rtmp.youtube.com/live2/YOUTUBE_KEY
The -c copy flag avoids re-encoding - just repackages the stream. Minimal CPU usage.
Platform-Specific Notes
Twitch
- Maximum bitrate: 6000 Kbps (8500 for partners)
- Audio: 160 Kbps AAC
- Keyframe interval: 2 seconds
YouTube
- Recommended bitrate: 4500-9000 Kbps for 1080p60
- Audio: 128 Kbps AAC
- More lenient on bitrate spikes
Kick
- Maximum bitrate: 6000 Kbps
- Similar to Twitch requirements
- RTMP ingest URL varies by region
VPS Requirements
| Setup | CPU | RAM | Bandwidth | |-------|-----|-----|-----------| | 2 platforms, passthrough | 1 core | 1GB | 20 Mbps | | 3 platforms, passthrough | 2 cores | 2GB | 30 Mbps | | 3 platforms + re-encode | 4 cores | 4GB | 30 Mbps |
Passthrough (no re-encoding) is extremely lightweight. A basic Space-Node VPS handles 3+ platforms with room to spare.
Reliability
Reconnection
Nginx-RTMP attempts reconnection automatically if a platform drops. Configure retry:
push rtmp://live.twitch.tv/app/KEY push_reconnect=3s;
Monitoring
Check stream health:
# View RTMP stats
curl http://localhost/stat
Add the stats module to see which streams are active and their bitrates.
Benefits
- Grow faster: Reach audiences on every platform simultaneously
- Platform independence: If one platform goes down, others stay live
- Lower cost: One VPS handles what used to require expensive restreaming services
- Full control: No third-party service limitations or branding requirements
