ffmpeg Node

Overview

This node provides functionality related to media file processing using ffmpeg. Specifically, for the "Metadata" resource with the "Extract Metadata" operation, it extracts metadata information from a given media file. This is useful when you want to analyze or retrieve details such as codec, duration, format, resolution, or other embedded metadata from audio or video files.

Common scenarios include:

• Automatically gathering media file properties before further processing.
• Validating media files by checking their metadata.
• Extracting technical details for cataloging or reporting purposes.

Example: You provide a URL or binary input of a video file, and the node outputs detailed metadata about that video.

Properties

Output

The node outputs a JSON object containing the extracted metadata of the provided media file. This typically includes fields such as format, streams (video/audio), codec information, duration, bitrate, and other relevant technical details.

If the input was provided as binary data, the node processes this binary content to extract metadata accordingly.

Dependencies

• Requires an API key credential for accessing the underlying ffmpeg service.
• The node depends on an external ffmpeg-based service or library to perform media analysis.
• No additional environment variables are explicitly required based on the static code.

Troubleshooting

• Invalid Media Input: If the media URL is invalid or the binary field does not contain a proper media file, the node may fail to extract metadata. Ensure the input is correct and accessible.
• Authentication Errors: Missing or incorrect API credentials will prevent the node from functioning. Verify that the API key credential is properly configured.
• Unsupported Media Format: Some media formats might not be supported by the underlying ffmpeg service, leading to incomplete or failed metadata extraction.
• Timeouts or Network Issues: When providing URLs, network connectivity issues can cause failures. Check URL accessibility and network status.
