Cubemap is a high-performance, high-availability video reflector, specifically made for use with VLC. A short list of features: - High-performance, through a design with multiple worker threads, epoll and sendfile (yes, sendfile); a 2GHz quadcore can saturate 10 gigabit Ethernet, given a modern kernel, a modern NIC and the right kernel tuning. - High-availability. You can change any part of the configuration (and even upgrade to a newer version of Cubemap) by changing cubemap.config and sending a SIGHUP; all clients will continue as if nothing had happened (unless you delete the stream they are watching, of course). Cubemap also survives the encoder dying and reconnecting. - Per-stream fwmark support, for TCP pacing through tc (separate config needed). - Support for setting max pacing rate through the fq packet scheduler (obsoletes the previous point, but depends on Linux 3.13 or newer). - Reflects anything VLC can reflect over HTTP, even the muxes VLC has problems reflecting itself (in particular, FLV). - IPv4 support. Yes, Cubemap even supports (some) legacy protocols. HOWTO: sudo aptitude install libprotobuf-dev protobuf-compiler make -j4 If you want to use HTTP input (you probably want to), you want VLC 2.2.0 or newer. Then start the VLC encoder with the “metacube” flag to the http access mux, like this: cvlc [...] --sout '#std{access=http{metacube,mime=video/x-flv},mux=flv,dst=:4013/test.flv}' Then look through cubemap.config.sample, copy it to cubemap.config, compile and start cubemap. To upgrade cubemap (after you've compiled a new binary), or to pick up new config: killall -HUP cubemap Cubemap will serialize itself to disk, check that the new binary and config are OK, and then exec() the new version, which deserializes everything and keeps going. Munin plugins: To activate these, symlink them into /etc/munin/plugins. If you don't put the files in the expected default locations (as done by 'make install'), you probably want some configuration in /etc/munin/plugin-conf.d/cubemap or similar, like this: [cubemap*] user env.cubemap_config /etc/cubemap/cubemap.config env.cubemap_stats /var/lib/cubemap/cubemap.stats env.cubemap_input_stats /var/lib/cubemap/cubemap-input.stats Legalese: Copyright 2013 Steinar H.
