This is a pre-processing (red) element. It is placed after a Source and possibly other audio processing elements, to insert metadata into the audio encoding. Metadata can be added from different origins, including HTTP(S) pulls, UECP or API calls.

The aixtream solution separates metadata into three levels.
Static metadata should be filled manually. Dynamic metadata should be updated via a metadata ingest. When a metadata tag is filled in multiple levels, the following priority is used:
The default workflow is designed around using these categories as described above. While it is recommended to use them as described, it is possible to configure them differently. For example, you can leave Overlay metadata and Fallback data unconfigured and have both dynamic and static metadata tags as Base metadata. Note that this may cause undesireable behavior in case of a loss of the metadata ingest. |
| Metadata Inserter element configuration | |
|---|---|
| Element | Description |
| Base metadata | Edit button. Opens the Editing metadata menu to enter static metadata or configure a metadata ingest. See info box above for details on Base metadata. |
| Overlay metadata | Edit button. Opens the Editing metadata menu to enter static metadata or configure a metadata ingest. See info box above for details on Overlay metadata. |
| Fallback data | Edit button. Opens the Editing metadata menu to enter static metadata or configure a metadata ingest. See info box above for details on Fallback data. |
| Fallback timeout | The time interval in seconds after a loss of a metadata ingest after which the fallback metadata is used instead of the overlay metadata. |
| Drop upstream data | Toggles whether existing metadata already present in the input audio is maintained or discarded. While “On”, existing metadata is discarded. |

| Name | Sets the pretty name for the metadata ingest. |
| UECP Input | |
| Protocol |
Dropdown to select the transport protocol for the input.

| Dropdown |
Selects one of two options:
|
| Inputs / Pull | |
| URL | Sets the URL from which metadata updates are pulled. |
| Update interval | Sets the interval after which an update is pulled. |
| Placeholder |
Defines placeholders for use in the tag fields below. Example: If “HTTP1” is set as a placeholder, you can use “%HTTP1” in any tag field. |
| Outputs / Push | |
| Dropdown | Dropdown to select the metadata API format for the push. |
| QuantumCast MetaPort only | |
| Channel Key | Sets the channel identifier for the MetaPort API. |
| MetaPort Token | Sets the access token for the MetaPort API. |
