register_camera_source()

uint64_t MayaFlux::IO::IOManager::register_camera_source

(

std::shared_ptr< CameraSource >

source

)

Assign a globally unique reader_id and take ownership of a CameraSource that is already open.

The backend-agnostic entry point for camera hosting: any CameraSource implementation, from any backend, is registered identically. open() and configuration are entirely the caller's concern beforehand — this call never touches either.

Parameters

source

Fully-opened CameraSource.

Returns

Globally unique reader_id assigned to this source.
