Here's my running config with FFMPEG if you'd like to compare:īut really, if you want to get the lowest latencies, look into intra-refresh ( ). It's all self-taught with virtually no media background though, so I'm very glad I've gotten as far as I have. It's been a fight with FFMPEG along the way with weird issues, but I've been trucking along somehow. The big latency crushers for me were -intra-refresh 1, -tune zerolatency, and -pix_fmt yuv420p. To be honest though, I should have much lower latencies (under 50ms at least, given they expect 10ms from an 800圆00 stream - ) so I'm still working on my setup.

I just subtracted the times in the picture. There's a screenshot of the actual time/method I used to find that latency.

As far as the encode goes, my aim was the lowest latency possible, so it absolutely eats at my processor. The stream was encoded and sent to a virtual machine, pushed back, and played in an embedded video player (Flowplayer because JWPlayer wouldn't get past some built-in buffer) on a webpage from the web server that I have the virtual machine setup as. LAN, technically, though it wasn't even that.
