| Performing Transcription of WebRTC Media Streams in Browser | Rob Pickering | 25m |
A Chrome extension captures tab audio via tabCapture and runs Whisper in WASM locally (tiny quantized Q5 model ≈50 MB, base ≈150 MB, larger models 0.5–2 GB)… | ||
| Building Jellyfish: Multimedia Server Powered by Membrane and Phoenix | Łukasz Wala | 23m |
Jellyfish is a multimedia SFU server built in Elixir, Membrane, Phoenix that accepts WebRTC peers and RTSP camera inputs and produces HLS outputs by composing… | ||
| Video Creation in a JavaScript World | Jonny Burger | 21m |

| Getting Started with WebRTC: An Outsider's View | Ritvi Mishra | 15m |
Starts from being stuck on jargon after "40 minutes" of reading, builds a word cloud to surface mental models, and shows a concrete path: use a TouchDesigner… | ||
| The User (has) Generated Content... so what now? | Bartosz Studnik | 22m |
Handles thousands of short UGC videos by adding a heavier analysis step, a normalization stage that fixes PCM audio, broken PTS, empty frames and HDR→SDR, and… | ||
| Concurrency, Functional Paradigm and Dynamic Flow Control in Multimedia Processing | Łukasz Kita | 28m |

| Different Strategies for Dynamic Media Pipelines in Recording Video Calls | Rishit Bansal | 19m |
Three practical pipelines: use the MediaRecorder API in-browser for quick client-side clips but risk lost recordings and high RAM as duration grows; run… | ||
| Sex, Lies & Videotapes: The Truth Behind Your CDN Logs | Javi B | 29m |
Claims that 95% of errors originate in the CDN and that routine 4:00 a.m. maintenance spikes explain odd overnight failures. Recommends multi‑CDN + redundancy… | ||
