DeckLinkDeviceIdentifier type

Stable DeckLink device identity, as reported per card by DeckLinkCard. cardIndex is just IDeckLinkIterator traversal order — it shifts whenever the visible device set changes (driver updates, added/removed cards, device-filtered containers); these identities do not. persistentID follows the physical card across slots; topologicalID follows the PCIe position; subDevice addresses one sub-device of a multi-device card by its device group and position within it.

Signature:

export type DeckLinkDeviceIdentifier = {
    idType: "persistentID";
    id: number;
} | {
    idType: "topologicalID";
    id: number;
} | {
    idType: "subDevice";
    deviceGroupId: number;
    subDeviceIndex: number;
};
