Overview
This node provides functionality related to media files using ffmpeg, a powerful multimedia framework. Specifically, for the "Metadata" resource with the "Extract Metadata" operation, it extracts metadata information from a given media file. This can be useful in scenarios where you need to analyze or process media files based on their properties such as duration, codec, resolution, bitrate, and other embedded metadata.
Practical examples include:
- Automatically retrieving video or audio metadata to decide further processing steps.
- Extracting technical details of media files for cataloging or reporting.
- Validating media files before upload or conversion by checking their metadata.
Properties
| Name | Meaning |
|---|---|
| Media File Input | A valid media URL or the name of the input binary field containing the media file to analyze. |
Output
The node outputs JSON data containing the extracted metadata of the provided media file. This typically includes detailed information about the media's format, streams (audio, video), codecs, duration, bitrates, and other relevant technical attributes.
If the input is provided as binary data, the node processes that media content directly. The output does not include binary data but rather structured metadata information derived from the media file.
Dependencies
- Requires an API key credential for accessing the underlying ffmpeg service.
- Depends on the external ffmpeg framework or service accessible via the configured API.
- No additional environment variables are explicitly required beyond the API authentication setup.
Troubleshooting
- Invalid Media Input: If the media URL or binary field name is incorrect or inaccessible, the node will fail to extract metadata. Ensure the input points to a valid media source.
- Authentication Errors: Missing or invalid API credentials will prevent the node from communicating with the ffmpeg service.
- 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 using URLs, network problems can cause failures; verify connectivity and URL accessibility.
Common error messages may indicate issues like "Unable to read media file," "Authentication failed," or "Unsupported format." Resolving these involves verifying inputs, credentials, and media compatibility.
