// Interface for an object capable of vending video frames. There is no

// pinned to a specific thread. Indeed, |VideoFrameFactory| implementations are
// created by cast on the main cast thread then used by unknown client threads
// via the |VideoFrameInput| interface.
//
// Clients are responsible for serialzing access to a |VideoFrameFactory|.
// Generally speaking, it is expected that a client will be using these objects
// from a rendering thread or callback (which may execute on different threads
// but never concurrently with itself).
