Multistreaming Mastery: Stream to Twitch, YouTube, and Kick

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:

1. You stream once to your VPS
2. The VPS restreams to multiple platforms
3. Your home upload: 6-10 Mbps (single stream)
4. 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

Passthrough (no re-encoding) is extremely lightweight. A basic Space-Node VPS handles 3+ platforms with room to spare. Those VPS plans are out of stock until about the end of October, though. If you would rather multistream straight from OBS on the server, our streaming VPS has OBS pre-installed.

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

1. Grow faster: Reach audiences on every platform simultaneously
2. Platform independence: If one platform goes down, others stay live
3. Lower cost: One VPS handles what used to require expensive restreaming services
4. Full control: No third-party service limitations or branding requirements

Kick RTMP and YouTube backup URL quick answers

For production multistreaming, document every platform target, keep stream keys outside Git, and add service restarts so one platform failure does not kill the whole pipeline.
