Demuxed 2025
Demuxed is video engineers talking about video technology
Our first meeting was a single day event back in 2015, born out of the SF Video Technology meetup. The video industry had plenty of trade shows and other opportunities for The Business, but our goal was to create a conference and community for the engineers building the technology powering video, from encoding, to delivery, to playback, and beyond. We’ve grown a lot since then, but our goal remains the same.
After creating Demuxed, some of the organizers went on to start and work at Mux. Mux continues to sponsor most of the organizational work behind the scenes (thanks for the salary!), but Demuxed is, at its core, a community-led event.
Every year we get a group together that’s kind enough to do things like schedule planning, help brainstorm cool swag, and, most importantly, argue heatedly over which talk submissions should make the final cut. These folks are the ones hanging out in Video Dev Slack, and they hail from all over the industry.
