on_attach()

void FrameAccessProcessor::on_attach ( const std::shared_ptr< SignalSourceContainer > &  container )

overridevirtual

Attach the processor to a video container.

Reads dimension metadata (TIME, SPATIAL_Y, SPATIAL_X, CHANNEL), caches frame geometry, initialises the temporal cursor, and marks the container ready for processing.

Parameters

container

The SignalSourceContainer to attach to.

Implements MayaFlux::Kakshya::DataProcessor.
