In order to support capture, the pipeline handler needs methods to allocate and free buffers, to start and stop the capture and to queue requests. Define those interfaces in the PipelineHandler class and implement them as stubs in the existing pipeline handlers. This initial implementation only considers the allocation of new buffers. Future work would need to expand this to also cover importing buffers from an external source.
