1 Cubemap is a high-performance, high-availability video reflector,
2 specifically made for use with VLC.
4 A short list of features:
6 - High-performance, through a design with multiple worker threads,
7 epoll and sendfile (yes, sendfile); a 2GHz quadcore can saturate
8 10 gigabit Ethernet, given a modern kernel, a modern NIC
9 and the right kernel tuning.
10 - High-availability. You can change any part of the configuration
11 (and even upgrade to a newer version of Cubemap) by changing cubemap.config
12 and sending a SIGHUP; all clients will continue as if nothing had happened
13 (unless you delete the stream they are watching, of course).
14 Cubemap also survives the encoder dying and reconnecting.
15 - Support for setting max pacing rate through the fq packet scheduler
16 (depends on Linux 3.13 or newer).
17 - Reflects anything VLC can reflect over HTTP, even the muxes VLC
18 has problems reflecting itself (in particular, FLV).
19 - Multicast support, both for sending and receiving (supports only protocols
20 that can go over UDP, e.g. MPEG-TS). Supports both ASM and SSM.
21 - IPv4 support. Yes, Cubemap even supports (some) legacy protocols.
26 sudo aptitude install libprotobuf-dev protobuf-compiler libsystemd-dev
29 If you want to use HTTP input (you probably want to), you want VLC 2.2.0
30 or newer. Then start the VLC encoder with the “metacube” flag to the http
31 access mux, like this:
33 cvlc [...] --sout '#std{access=http{metacube,mime=video/x-flv},mux=flv,dst=:4013/test.flv}'
35 Then look through cubemap.config.sample, copy it to cubemap.config,
36 compile and start cubemap.
38 To upgrade cubemap (after you've compiled a new binary), or to pick up new
43 Cubemap will serialize itself to disk, check that the new binary and config
44 are OK, and then exec() the new version, which deserializes everything and
50 To activate these, symlink them into /etc/munin/plugins. If you don't put
51 the files in the expected default locations (as done by 'make install'),
52 you probably want some configuration in /etc/munin/plugin-conf.d/cubemap or
57 env.cubemap_config /etc/cubemap/cubemap.config
58 env.cubemap_stats /var/lib/cubemap/cubemap.stats
59 env.cubemap_input_stats /var/lib/cubemap/cubemap-input.stats
