Learning courses
Structured knowledge bases that walk through a topic end-to-end. Read in order, jump by chapter, or use the glossary as a reference. One more course ship in Q3 2026.
01 · Course
Codecs through 2030 — AV1, AV2, H.266, H.267, and end-to-end learned compression.
02 · Course
Video delivery end to end — HLS, DASH, LL-HLS, WebRTC, adaptive bitrate, CDNs, and DRM.
03 · Course
Computer vision, speech, multimodal models, generative video, real-time inference, and AI agents.
04 · Course
Sample rate, loudness, AAC, Opus, LUFS, the WebRTC audio pipeline, lip-sync, and Dolby Atmos.
05 · Course
IP cameras, ONVIF, RTSP, VMS and NVR, edge and cloud video analytics, and privacy compliance.
06 · Course
Clinical video with HIPAA compliance, WebRTC, EHR/FHIR integration, e-prescribing, and clinical AI.
07 · Course
Ingest to analytics — encoding ladder, CDN cost, multi-DRM, SVOD/AVOD/TVOD/FAST monetization, and QoE.
08 · Course
SCORM and xAPI, LTI and cmi5, interactive video, virtual classrooms, AI tutors, and learning analytics.
09 · Course
PSNR, SSIM, VMAF, subjective testing, artifact analysis, production QC, and streaming QoE benchmarks.
Architecture guides
Each guide is a long-form architecture explainer covering tradeoffs, vendor stack choices, scaling concerns, and what we'd do differently if we built it again.
01
Most read"P2P breaks at ~6 participants. Here's the SFU math."
02
Start here"Cloud at $0.005 per minute. Self-host at 10K minutes — the math flips fast."
03
"Sub-second translation is a budget, not a feature. Here's how to spend it."
04
"Vision, voice, reasoning — pick two for under 500 ms. The third costs."
05
"The vendor's demo runs on one user. Your product runs on 10K. Plan the gap."
06
Latest"Build vs buy is rarely the right question. It's almost always 'where do you draw the seam'."
