Function: isMetadataProperty()

function isMetadataProperty(name: string): boolean;

Defined in: packages/player/src/properties.ts:384

Whether a property change means "the current entry's metadata changed".

Both names are invalidated by mpv's single MP_EVENT_METADATA_UPDATE (player/command.c: E(MP_EVENT_METADATA_UPDATE, "metadata", "filtered-metadata", "media-title")), and either arriving is enough. Two triggers rather than one because mpv only re-emits an observed property when its value compares unequal (player/client.c, send_client_property_changes): if the metadata string read ever fails — which is what the manual says should happen — that observation goes quiet after its initial event, and media-title still carries ICY now-playing changes.
