=== DESCRIPTION ============================================================== Loomiere is a highly scalable and secure HTTP a/v streaming server able to serve a massive amount of streaming requests simultaneously using commonly available (commodity) hardware. It makes use of a bandwidth conservation algorithm designed to provide smooth playback, which, together with many other features, cuts down streaming production costs considerably. See the features described further down for more detailed information. === TERMS ==================================================================== See the LICENSE file! Copyright (C)2010 Valeriu Paloş. All rights reserved. === FEATURES ================================================================= - Able to serve *massive* amounts of clients simultaneously. Visit http://valeriu.palos.ro/980/loomiere-2-0-teaser-reloaded/ for some real-life data. - Very lightweight, built for maximum throughput on multi-core machines and specifically designed to completely eliminate software bottlenecks (e.g. it should allow you use your hardware components to the full physical extent). - Strong bandwidth conservation that uses a smart and easy to configure throttling system which is VBR-aware (variable bitrate) for smooth playback. - High-speed memory-based cache to accelerate request responses. - URL Rewriting/Redirection: Support for URL routing using regular expressions or even custom Lua scrips, making it very easy to integrate with (or replace) another existing system. - Virtual Hosting: Name-based virtual hosting support with regular expression matching. - Monitoring: Detailed statistics published on separate port at "/monitor" URL. === REQUIRED ================================================================= - Lua(5.1) ............ http://www.lua.org/ - Luarocks ............ http://www.luarocks.org/ - alt-getopt ...... http://luaforge.net/projects/alt-getopt/ - lpeg ............ http://www.inf.puc-rio.br/~roberto/lpeg/lpeg.html - luabitop ........ http://bitop.luajit.org/ - lua-ev .......... http://github.com/brimworks/lua-ev - lrexlib-pcre .... http://lrexlib.luaforge.net/ - luasocket ....... http://w3.impa.br/~diego/software/luasocket/ - LibEV ............... http://software.schmorp.de/pkg/libev.html - PCRE ................ http://www.pcre.org - TokyoCabinet ........ http://fallabs.com/tokyocabinet/ === COMPILE ================================================================== Currently I only compiled this on Debian and Ubunutu (other distros should work with minor editing of makefiles). Just run: $ make -f makefile.ubuntu === SUGGESTED ================================================================ To run Loomiere in production you should use a service supervisor such as: - runit ............... http://smarden.org/runit/index.html === CHANGE LOG =============================================================== Loomiere 2.0.1-beta - 2011-12-07 - Minor bug fixes and improvements. Loomiere 2.0-beta - 2010-08-15 - First working release of Loomiere (2.0). === IDEAS ==================================================================== - Anti-DOS Prevention System: Based on the number of connections per second coming from a single IP. - Whitelist/Blacklist: Banning system based on a list of IPs and/or referrer domains. - Throttling Hinting: adaptive throttling based on hint commands sent by the player during playtime. This interprets calibration hints from the video-player during playtime and also enables streaming to be suspended while the player is paused (but only if there is enough bandwidth to ensure smooth playback on resume). - Controlled Client Identity: Content protection based on token exchange (via custom Lua script). This will deny streaming everywhere except in your custom-compiled players and also will prevent others to download your movies straight from the server. - Controlled Domain Identity: Serve certain media only when the player comes from specific domains. This will deny streaming everywhere except in video-players coming from specific domains. - Geo-location: Controlled access based on geo-location information (via GeoIP). This can currently be achieved by using GeoIP from the options.lua file (in Lua) but I guess it should be nicer. - Loomiere must run as user 'loomiere' (not as 'root'). - Re-organized host definition in options.lua. - Add ability to respond with HTTP error codes (302, 404, 500 etc.) straight from the host's URL routing table (in options.lua). - Add (optional) HTTP caching headers (for selected types of files). - Add '?terse=true|false' parameter to the '/monitor' URL. - Add '/space?path=/var/www' control parameter to check disk usage. - Add multiple sandbox paths for each host, with individual statistics.
