hook_video_container_to_buffer()

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

(

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

container

)

Wire a video container to the graphics buffer system.

Creates a VideoContainerBuffer via BufferManager with GRAPHICS_BACKEND token, stores it keyed by container pointer, and returns it. A VideoFileContainer or a DynamicVideoStream can be wired. A DynamicVideoStream needs frames or an enabled ring before it can be hooked, and gets its seek processor.

Parameters

container

Video container to wire.

Returns

Created VideoContainerBuffer, or nullptr on failure.
