It's for implementing Cisco's clearpath technology (http://www.cisco.com/c/dam/en/us/td/docs/telepresence/endpoint/software/clearpath/clearpath_whitepaper.pdf) Basically one would periodically mark a P frame as long term reference, in case of packet loss one can thus refer to this one instead of restarting the stream with an idr. I'm not too concerned about the encoding speed as long as it's above realtime (60fps 1920x1080)
