ffmpeg Node

Overview

The node provides functionality to start RTMP restreaming of a media file. It takes an input media source (either a URL or a binary media file) and streams it to a specified RTMP URL. This is useful in scenarios where you want to broadcast or redistribute live or prerecorded media content to streaming platforms that accept RTMP input, such as YouTube Live, Twitch, or custom streaming servers.

Practical examples:

• Restream a recorded video file to a live streaming platform.
• Redirect a live media feed from one source to multiple RTMP endpoints.
• Automate streaming workflows by integrating with other n8n nodes for media processing before restreaming.

Properties

Output

The node outputs JSON data representing the result of the restreaming operation. The exact structure is not detailed in the provided code, but typically it would include status information about the streaming session, such as success confirmation, error messages if any, or 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 in the provided snippet.

Dependencies

• Requires an API key credential for the underlying ffmpeg-related service or API.
• Depends on an external ffmpeg-based service or library capable of handling RTMP restreaming.
• The node internally uses a router mechanism (router.call(this)) to delegate execution to appropriate handlers, which likely manage the actual streaming logic.

Troubleshooting

• Invalid Media Input: If the media input URL or binary field is invalid or inaccessible, the node may fail to start the stream. Ensure the media source is reachable and correctly specified.
• Invalid RTMP URL: Providing an incorrect or malformed RTMP URL will cause connection failures. Verify the RTMP endpoint format and credentials if required.
• Credential Issues: Missing or incorrect API authentication tokens can prevent the node from functioning. Confirm that the necessary API key or authentication token is configured properly.
• Streaming Failures: Network issues or server-side problems at the RTMP destination can interrupt streaming. Check network connectivity and RTMP server status.
• Error Messages: The node might throw errors related to ffmpeg processing or connection timeouts. Review error details to identify whether the issue is with input media, network, or configuration.
