Cross-Application

Having producers and consumers in separate applications requires inter-process communication during every step of the process. At setup, all the requirements must be transmitted between the endpoints, and then the allocated objects must be shared between the processes. During streaming, every time the producer generates a frame, a message letting the consumer know it is ready, which includes the fence, must be sent to the other side. When the consumer is done reading from the frame, a similar message must be sent back in the other direction. Each application must be prepared to read and process these messages so streaming can occur in a timely fashion.
