NAME

pw-metadata - The PipeWire metadata

SYNOPSIS

pw-metadata [/options/] [/id/ [/key/ [/value/ [/type/ ] ] ] ]

DESCRIPTION

Monitor, set and delete metadata on PipeWire objects.

Metadata are key/type/value triplets attached to objects identified by id. The metadata is shared between all applications binding to the same metadata object. When an object is destroyed, all its metadata is automatically removed.

When no value is given, pw-metadata will query and log the metadata matching the optional arguments id and key. Without any arguments, all metadata is displayed.

When value is given, pw-metadata will set the metadata for id and key to value and an optional type.
