hook_camera_to_buffer()

std::shared_ptr< Buffers::VideoContainerBuffer > MayaFlux::IO::IOManager::hook_camera_to_buffer

(

const std::shared_ptr< Kakshya::CameraContainer > &

container

)

Wire a CameraContainer to the graphics buffer system.

Creates a VideoContainerBuffer via BufferManager with GRAPHICS_BACKEND token, stores it keyed by container pointer, and returns it. Identical to hook_video_container_to_buffer() but accepts CameraContainer.

Parameters

container

Opened CameraContainer from open_camera().

Returns

Created VideoContainerBuffer, or nullptr on failure.
