##
## - san2(at)linuxchannel.net
##
## - 2003.04.29(Ver 0.6.7)
## fixed '+' string for user agent guly parsing
## - 2003.01.05(Ver 0.6.6)
## small bug fixed
## - 2002.08.20(Ver 0.6.5)
## support vorbis OGG file
## support RMA(ReadMedia-Player)
## support Zinf(FreeAmp)
## support XMPlay(win)
## - 2002.05.15(Ver 0.5)
## support access logging
## security
## support direct access(such as xmms, winamp ...), then random playing
## - 2002.05.14(Ver 0.3)
## support PHP/4.0.x
## - 2002.05.13(Ver 0.2)
##
## [download]
## - http://ftp.linuxchannel.net/devel/php_stream/
##
## There is no need to use together.
## (such as icecast, apache-mp3, mod_mp3 streaming server)
##
## [reference]
## 0. if mime type isn't registered by IANA(->ICANN),
## adding a "x-" before the subtype
## 1. /usr/local/apache/conf/mime.types.default
## 2. http://sander.vanzoest.com/talks/apachecon/2001/notes/notes_apachecon.txt
## 3. http://www.mp3dev.org/ support mp3 bitrate(use lame)
## 4. RFC 1806, The Content-Disposition Header
## 5. RFC 3003, The audio/mpeg Media Type
## 6. vorbis OGG : http://www.xiph.org/ and http://www.vorbis.com/faq.psp
##
## [test]
## 1. Linux/2.4 (redhat 7.x)
## 2. Apache/1.3.x
## 3. PHP/4.2.x PHP/4.1.x, PHP/4.0.x
## 4. useragent :
## - MSIE5/6
## - netscape/4,6 (linux,win)
## - mozilla/0.9.x(linux)
## - xmms/1.2.x(linux) : ok
## - winamp(win) : ok
## - winmap3(win) : ok
## - Zinf(FreeAMP) : ok
## - XMPlay(win) : ok
## - RMA, RealMedia-Player(win) : ok
## - Window-Media-Player(win) : fail
## - NSPlayer(win) : fail
## 5. test only *.mp3(korean file name success)
## 6. support lame(only *.mp3 bitrate)
## 7. support access log write(options)
## 8. support direct access(such as xmms, winamp ...)
## 9. support vorbis OGG file
##
## [TODO] - I just think.
## 1. user auth(option)
## 2. check more useragent
## 3. more useragent support
## 4. ID3tag support
## 5. mp3 list view and select playing(unit readdir()).
## 6. etc, .... T.T
##
## enjoy !!!
