Hong Kong VPS for Live Streaming: RTMP Server for Twitch, YouTube & Bilibili (2026)

Live streaming from mainland China or Southeast Asia to global platforms like Twitch and YouTube involves a fundamental routing problem: your home internet connection exits through congested international routes, causing dropped frames, stream instability, and inconsistent upload speeds. A Hong Kong VPS as an RTMP relay server solves this — you stream once from your home to Hong Kong over a stable CN2 GIA path, and the VPS re-streams to all your platforms simultaneously with reliable, dedicated bandwidth.

This guide sets up an RTMP relay server on a Hong Kong VPS using Nginx-RTMP, enabling simultaneous streaming to Twitch, YouTube, and Bilibili (哔哩哔哩) with low latency for Asia-Pacific viewers.

Why Hong Kong VPS for Streaming?

• Stable upload path — CN2 GIA routing gives mainland China streamers a consistent, low-jitter path out of China to the VPS, reducing dropped frames from unstable residential ISP routes
• Geographic advantage — Hong Kong is well-connected to both Asian CDNs (Bilibili, Douyu, Huya) and global platforms (Twitch Frankfurt ingest, YouTube primary ingest)
• Multi-platform simultaneous streaming — stream once to your VPS; the VPS pushes to all platforms in parallel
• Low latency for Asian viewers — Bilibili and Asian-focused platforms have ingest points near Hong Kong, giving Asian viewers lower latency than streaming from Europe or US
• Transcoding capability — the VPS can transcode your stream to multiple resolutions (1080p/720p/480p) for platforms that don’t transcode automatically

Required VPS Specifications

For relay-only (no transcoding) — which is sufficient for most streamers — a 2 GB VPS handles the workload comfortably. CPU transcoding requires significantly more compute.

Step 1: Install Nginx with RTMP Module

apt update && apt upgrade -y
apt install -y build-essential libpcre3 libpcre3-dev libssl-dev \
  zlib1g zlib1g-dev libnginx-mod-rtmp nginx

Verify the RTMP module is available:

nginx -V 2>&1 | grep rtmp

If the package version doesn’t include the RTMP module, build from source:

# Build Nginx with RTMP module from source
apt install -y libpcre3-dev zlib1g-dev libssl-dev
wget http://nginx.org/download/nginx-1.25.3.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.tar.gz -O nginx-rtmp-module.tar.gz

tar xzf nginx-1.25.3.tar.gz
tar xzf nginx-rtmp-module.tar.gz

cd nginx-1.25.3
./configure \
  --prefix=/etc/nginx \
  --sbin-path=/usr/sbin/nginx \
  --modules-path=/usr/lib64/nginx/modules \
  --conf-path=/etc/nginx/nginx.conf \
  --with-http_ssl_module \
  --with-http_v2_module \
  --add-module=../nginx-rtmp-module-master

make -j$(nproc)
make install

Step 2: Configure Nginx RTMP for Multi-Platform Streaming

Edit /etc/nginx/nginx.conf — add the RTMP block at the end, outside the http {} block:

rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        timeout 30s;

        application live {
            live on;
            record off;
            
            # Stream key authentication
            on_publish http://127.0.0.1:8080/auth;

            # Push to Twitch
            push rtmp://live.twitch.tv/app/YOUR_TWITCH_STREAM_KEY;

            # Push to YouTube
            push rtmp://a.rtmp.youtube.com/live2/YOUR_YOUTUBE_STREAM_KEY;

            # Push to Bilibili
            push rtmp://live-push.bilivideo.com/live-bvc/YOUR_BILIBILI_RTMP_KEY;

            # Push to additional platforms as needed
            # push rtmp://sg.pushlive.douyu.com/live/YOUR_DOUYU_KEY;
        }
        
        application local {
            live on;
            record off;
            # Local-only stream (no push) for recording or monitoring
        }
    }
}

nginx -t && systemctl reload nginx

# Open RTMP port in firewall
ufw allow 1935/tcp

Step 3: Set Up Stream Key Authentication

Without authentication, anyone who finds your RTMP endpoint can push a stream to it. Add a simple authentication layer:

apt install python3-flask -y

cat > /opt/rtmp-auth/auth.py << 'EOF' from flask import Flask, request app = Flask(__name__) VALID_KEYS = {"YOUR_PRIVATE_STREAM_KEY"} @app.route('/auth', methods=['POST']) def auth(): key = request.form.get('name', '') if key in VALID_KEYS: return '', 200 return '', 403 if __name__ == '__main__': app.run(host='127.0.0.1', port=8080) EOF # Run as a systemd service cat > /etc/systemd/system/rtmp-auth.service << 'EOF'
[Unit]
Description=RTMP Auth Service
After=network.target

[Service]
ExecStart=python3 /opt/rtmp-auth/auth.py
Restart=always

[Install]
WantedBy=multi-user.target
EOF

systemctl enable --now rtmp-auth

In Nginx RTMP config, the on_publish callback checks your stream key before allowing the push. Only streams with your private key are accepted.

Step 4: Configure OBS to Stream to Your VPS

In OBS Studio:

1. Open Settings → Stream
2. Service: Custom…
3. Server: rtmp://YOUR_HK_VPS_IP/live
4. Stream Key: YOUR_PRIVATE_STREAM_KEY

Your OBS stream goes to Hong Kong; the VPS distributes to Twitch, YouTube, and Bilibili simultaneously.

Step 5: Add an HLS Stream for Web Playback

Add HLS output to serve your stream directly from your VPS via HTTP — useful for embedding on your own website or providing a backup viewing option:

application live {
    live on;
    record off;
    
    # HLS output
    hls on;
    hls_path /var/www/hls;
    hls_fragment 2s;
    hls_playlist_length 10s;
    
    # Push to platforms...
}

mkdir -p /var/www/hls
chown -R www-data:www-data /var/www/hls

Add to Nginx HTTP block to serve HLS:

location /hls {
    types {
        application/vnd.apple.mpegurl m3u8;
        video/mp2t ts;
    }
    root /var/www;
    add_header Cache-Control no-cache;
    add_header Access-Control-Allow-Origin *;
}

Your stream is then playable at https://yourdomain.com/hls/YOUR_STREAM_KEY.m3u8 in any HLS-compatible player.

Step 6: Monitor Stream Health

Add the RTMP statistics endpoint to monitor active streams:

http {
    server {
        listen 8088;
        location /rtmp-stat {
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }
        location /stat.xsl {
            root /usr/share/nginx/html;
        }
    }
}

Access http://YOUR_VPS_IP:8088/rtmp-stat (restrict access with ufw to your IP only) to see active connections, bitrate, and stream health in real time.

Bandwidth Planning

Calculate your monthly bandwidth requirement:

• Typical 1080p60 stream: 6 Mbps upload from OBS to VPS
• VPS outbound to 3 platforms at 6 Mbps each: 18 Mbps
• 4 hours streaming per day × 30 days × 18 Mbps = ~97 GB/month outbound

Most Server.HK VPS plans include generous monthly bandwidth allocations sufficient for regular streaming schedules. Check your plan’s bandwidth allocation and ensure it covers your streaming hours.

Latency Comparison: Direct vs VPS Relay

Conclusion

A Hong Kong VPS as an RTMP relay server solves the live streaming bottleneck for Asia-Pacific content creators — stable upload over CN2 GIA routing eliminates the dropped frames and reconnections that plague direct streaming from mainland China, and simultaneous multi-platform push to Twitch, YouTube, and Bilibili is handled automatically by Nginx-RTMP.

For streamers, the cost is minimal — a 2 GB VPS handles relay-only streaming comfortably — and the improvement in stream quality and stability is immediate and measurable in your OBS statistics.
