Conference Recording and Streaming
summary
A report on eight years of in-house conference recording and streaming describes a publishing pipeline built around media.ccc.de, SDI cameras feeding encoder cubes that produce three‑minute MPEG‑TS chunks via a patched ffmpeg, and a FuseTS FUSE filesystem plus tracker that auto‑generates Kdenlive projects. The stack includes nginx‑rtmp/HLS, Icecast for webm, haproxy for HTTP scaling, and hardware like Minions and 10Gbps Xeon edges reaching ~10 GBit; remaining issues are CPU‑bound webm encoding, framegrabber/EDID problems, and ongoing fixes such as voctomix and hdmi2usb, with a core team of about 15 people.
