|---|---|---|
| Measuring Perceptual Video Quality at Scale | Anne Aaron | 33m |
A concrete metric is available: open‑sourced VMAF model that fuses VIF and DLM plus a simple temporal feature via support‑vector regression to predict… | ||
| Why People Really Abandon Playbacks | Steve Robertson | 46m |
Many observational studies misidentify cause and effect; YouTube A/B experiments and ABR analysis show faster playbacks actually lower retention and paradoxes… | ||
| In a Perfect World: Why Media Sources Are a Hassle | David LaPalomento | 31m |
Media Source Extensions (MSE) promise adaptive web video but practical workarounds matter: fragmented MP4s and HLS transmuxing expose a recurring gap in… | ||
| Hardware Encoding in a Container | Adam Brown | 26m |
Running FFmpeg in Docker can leverage hardware encoders but requires exact kernel module and user‑space driver matching and device nodes on the host, otherwise… | ||
| WebRTC: From The Ground Up | Nick Chadwick | 37m |
Walks the protocol stack from discovery to media so you know what actually runs and what you must implement: ICE with STUN and TURN for NAT traversal… | ||
| ogv.js: Rebuilding the Web Video Stack From Scratch in JS | Brion Vibber | 33m |
ogv.js reconstructs the HTML5 video stack in pure JavaScript and actually plays Ogg/WebM where browsers lack support, using asm.js-compiled libtheora/libvorbis… | ||
| DASHing Into the Wild with VP9 | Pooja Madan, Nuno Pinge | 26m |
JW Player’s VP9 over DASH implementation claims ~50% bitrate savings at higher resolutions and uses libvpx/ffmpeg/WebM with Shaka and JW Player for MSE… | ||
| Popcorn Reborn! Open Video Editor from Mozilla | Tracey Jaquith | 31m |
PopcornMaker gets rebuilt as a mostly client-side only web editor that rips out the backend, runs faster, and lets projects be saved to archive.org (anonymous… | ||
| Developing VR Media Technology | Andrew Scherkus | 31m |
Prototype GoPro jump rig outputs 5,700×2,800 stereo at 60 fps (~2 billion pixels/sec) and exposes a real problem: current codecs hit H.264 level limits so… | ||
| An overview of AOM: The Alliance for Open Media | Jai Krishnan | 28m |
Seven companies form the Alliance for Open Media to produce AV1 an open and royalty-free next gen codec targeting ~50% bitrate savings over VP9 with full spec… | ||
