Analyze Media Package Workflow Operation

ID: analyze-mediapackage

Description

The analyze media package operation analyzes the mediapackage and sets workflow instance variables based on the content of the medapackage. These variables can then be used to control if workflow operations should be executed or skipped.

Workflow Instance Variables

Name	Example	Description
*flavor*_exists	presenter_source_exists=true	Whether an element with given flavor is in the mediapackage.
*flavor*_type	presenter_source_type=Track	The type of the element with the given flavor. Possible values are: Attachment, Catalog, Track.
*flavor*_hastag_*tag*	presenter_source_hastag_archive	Whether an element with given flavor and tag is in the mediapackage (only if set-tag-variables is set).

Parameter Table

If no configuration keys are specified, workflow instance variables will be set for every mediapackage element.

If no mediapackage element matches a configuration key, no workflow instance variables will be set for that key. For example, the operation will never generate presentation_work_exists=false.

Configuration Key	Example	Description
source-flavors	*/work	The comma separated list of flavors of the elements we are interested in.
source-tags	delivery, 1080p	The comma separated list of tags of the elements we are interested in.
set-tag-variables	true	Whether to set tag variables (default: false).
