/**
 A stable public description of the source being evaluated by a
 ``VideoAssetTransportProvider``.

 This type exists to give external transports the information they need to match
 and configure loading without exposing `expo-video`'s internal `VideoSource`
 model directly. This allows us to more easily introduce changes to `VideoSource`
 while keeping compatibility with external modules.
