Low-Latency Video Streaming

Live video pipelines over RTSP, WebRTC, SRT, RTMP and HLS, designed against an agreed latency budget and tested on the networks you actually have.

Live video is a chain of buffers, and every stage adds delay: capture, encoder lookahead and frame reordering, packetization, the network, the receiver’s jitter buffer, decoding and display. I start by agreeing a glass-to-glass budget with you, then choose the transport and encoder settings that can meet it. Protocol choice follows the network and the audience: RTSP with RTP over UDP is the norm for IP cameras on a LAN. Interleaving RTP inside the RTSP TCP connection helps through firewalls, at the cost of stalls when packets are lost. WebRTC delivers sub-second, interactive video through…
