Bypassing dumpcap with TShark and pipes

Because of Bug 2874 in dumpcap, tshark will normaly only respond every 500ms. I need lower latency as I am feeding a live application. I heard this can be accomplished with pipes, but am completely inexperienced with pipes. How would this be done? What I need is for the dissectors to be running in realtime, continually.

Did you mean dumpcap -w - -P | tshark -r - ? Or does dumpcap spawned by tshark really behave differently if that tshark writes to stdout than if it writes to a regular file?
