I'm by no means an x264 expert, but the encoder tuning may not be the only thing to take into consideration: http://stackoverflow.com/a/20244541 "What you want to do for low latency encode is to use CBR, and set the VBV buffer to the size of one frame, exactly. This enables a special VBV calculation, if you look in the x264 source." Technical details are here: http://x264dev.multimedia.cx/archives/249 and it does sound as if you need to do stuff in addition to the "-tune" parameter: "Because with –tune zerolatency, single-frame VBV, and intra refresh, x264 can achieve end-to-end latency (not including transport) of under 10 milliseconds for an 800×600 video stream."
