Articles, notes, and development tutorials
The history, design and real-world operation of ONVIF: from the 2008 agreement to Profile T and Profile V. WS-Discovery, profiles, WS-Security, GetStreamUri — with request examples and an analysis of where cameras break the standard.
Why designing an Edge node for an Edge-first VSaaS calls for a different approach. Security, reliability, hardware efficiency, co-design, and end-to-end observability: five new paradigms, the target architecture of an autonomous node, and which parts of it belong in the first “Walking Skeleton.”
The history of the RTP protocol, its packet format and the main difficulties of assembling video: fragmentation (FU-A and FU), Sequence Number arithmetic, the jitter buffer, synchronization via RTCP and the quirks of real IP cameras. With references to RFCs and tested Rust code.
Why a standard created for streaming multimedia in the late 1990s still underpins video capture from IP cameras, what trade-offs are built into its architecture, and which quirks of real hardware are worth taking into account. With references to RFCs and notes on what to verify on your own cameras.
