ffmpeg Node

Overview

The node provides functionality related to FFmpeg operations, including RTMP restreaming. Specifically, the "Start Restream" operation under the "RTMP Restreaming" resource allows users to stream a media file to a specified RTMP URL. This is useful for live broadcasting scenarios where you want to take an existing media file or stream and push it to an RTMP server, such as streaming to platforms like YouTube Live, Twitch, or custom RTMP endpoints.

Practical examples include:

• Streaming a prerecorded video file to a live RTMP server.
• Restreaming a media input from another source to a different RTMP destination.
• Automating live broadcasts by triggering restreams via workflows.

Properties

Output

The node outputs JSON data representing the result of the restreaming operation. While the exact structure is not detailed in the provided code, typically this would include status information about the streaming process, such as success confirmation, error messages if any, and possibly metadata about the stream.

If the node supports binary data output (e.g., processed media files), it would be included in the output's binary fields, but this is not explicitly shown here.

Dependencies

• Requires an API key credential for FFmpeg-related services (referred generically as "an API key credential").
• Depends on FFmpeg functionality exposed via an external service or API.
• The node internally uses a router mechanism to delegate execution to specific action handlers, including one for restreaming.

Troubleshooting

• Invalid Media Input: If the media file input URL or binary field name is incorrect or inaccessible, the restream will fail. Ensure the media source is valid and reachable.
• Invalid RTMP URL: Providing an incorrect or malformed RTMP URL will cause connection failures. Verify the RTMP endpoint format and credentials if required.
• API Credential Issues: Missing or invalid API authentication tokens can prevent the node from executing FFmpeg operations. Confirm that the necessary API credentials are configured correctly in n8n.
• Timeouts or Network Errors: Streaming requires stable network connectivity. Network interruptions may cause errors during restreaming.
• Error Messages: The node may throw errors related to FFmpeg processing or connection issues. Review error details in the node execution logs to identify specific causes.
