NGINX RTMP模块无法手动控制录制，请求技术支持

Hey Pedro, let's get that manual recording control working properly for your NGINX RTMP setup. The issue with your current config is that it's still set to auto-record streams by default—here's how to adjust it step by step:

Key Issues in Your Current Config #

Your recorder block uses record all manual;, which tells NGINX to target all streams for recording (even with a manual trigger). Plus, there's no explicit setting to disable automatic recording at the application level, so NGINX falls back to default behavior.

Modified Working Config #

Replace your existing RTMP server block with this adjusted version:

rtmp {
    server {
        listen 1935;
        chunk_size 4000;
        notify_method get;

        application live {
            live on;
            hls on;
            hls_path /hls/;
            hls_fragment 20s;
            hls_playlist_length 60;
            
            # Disable auto-recording by default for all streams in this app
            record off;

            recorder rec {
                # Enable manual-only recording trigger via HTTP control API
                record manual;
                record_path /mp4/;
                record_suffix .flv;
                record_notify on;
            }
        }
    }
}

What Changed & Why #

• record off; at the application level: This overrides any default recording behavior, ensuring NGINX won't start recording streams automatically when they're pushed to the live application.
• record manual; in the recorder block: This removes the redundant all flag and explicitly tells NGINX that this recorder should only activate when triggered by your HTTP control endpoints.

Verification Steps #

1. Restart NGINX to apply the config changes:

   sudo systemctl restart nginx  # For systemd-based systems
   # OR
   sudo service nginx restart    # For older init systems
   

2. Push a test stream to rtmp://your-server-ip/live/your-stream-name—you shouldn't see any .flv files appearing in /mp4/ automatically.
3. Trigger recording via your start endpoint:
   https://mydomain:8080/control/record/start?app=live&name=your-stream-name&rec=rec
   Check /mp4/—you should now see the recording file being created.
4. Stop recording with your stop endpoint:
   https://mydomain:8080/control/record/stop?app=live&name=your-stream-name&rec=rec
   The recording file will be finalized and saved in /mp4/.

Quick Troubleshooting Tip #

If recording still doesn't work as expected, check NGINX's error log (usually located at /var/log/nginx/error.log) to ensure:

• The NGINX process has read/write permissions for the /mp4/ directory.
• Your control endpoint requests are reaching NGINX (check for any 404 or permission errors in the logs).
