It is currently in alpha stage. -Copyright 2013 Steinar H. Gunderson . -Licensed under the GNU GPL, version 2. +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). + - 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), patch VLC with the +included file vlc-metacube.diff. 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: -More information to come here, later. :-) + 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.
