-
-v 0.2g (3rd August 2002):
-- finally fixed the bug that made oggcast~ crash after a
- while. seems to be realted with output from child thread
- using t_clocks but couldn't proove that
-
-v 0.2f (20st july 2002):
-- recompiled with the final 1.0 release of Ogg Vorbis
-- changed the URL to the new akustische-kunst.org domain
-
-v 0.2e (5th july 2002):
-- added simple downsampling to stream at lower sample rates
-
-v 0.2d (21st june 2002 - stable release!):
-- cleaned up code a bit
-- now clean disconnect in case server dies or closes
- socket
-
-v 0.2c (13th june 2002):
-- fixed some small bugs
-- buffer size now in kbytes per channel
-- some more info-printout
-
-v 0.2b (12th june 2002):
-- completetly rewritten multithreaded version, first
- sort of stable release
-- KNOWN BUG: eats too much CPU power
-
-v 0.1g (23rd feb. 2002, not for public use!):
-- added multithreading functionality: now sending data
- to server in a second thread
-- now included the static ogg vorbis libraries - no dll's
- needed under win any longer
-- fixed a bug that sometimes made pd crash
-
-v 0.1f (11th feb. 2002):
-- converted ringbuffer to simple buffer of fixed size
-
-v 0.1e (10th feb. 2002):
-- now really fixed the bug that made pd die when server
- disconnected
-
-v 0.1d (9th feb. 2002):
-- fixed a bug in the "vorbis" setting that made on-the-run
- changes impossible
-- introduced a function to check writeability of the socket
-- fixed the bug that crashed pd due to an access violation
- in vorbis.dll when send() returned an error (more of a
- fast workaround)
-- corrected bitrate setting, now it really is _k_bps
-
-
-v 0.1c (9th feb. 2002):
-- added support for setting / changing the comment tags in
- the ogg/vorbis header, spaces have to be replaced by '='
-- fixed a bug in oggcast_stream() that made Pd crash - now
- it's vorbis.dll that makes Pd crash... ;-(
-
-v 0.1b (not released):
-- added support for changing encoder settings when stream
- is running (no need to disconnect), seems to be unstable
- on linux (with JRoar)

-oggcast~ is a ogg/vorbis streaming external for pd (by Miller
-Puckette) that connects to an IceCast2 server.
-
-
-To run oggcast~ place the file oggcast~.dll for win or oggcast~.pd_linux
-in the directory of our patch or start pd with '-lib oggcast~' flag.
-
-To compile oggcast~ on Linux get the ogg/vorbice library from
-http://www.vorbis.com/.
-You have to modify the makefile to make it point to the place where the
-ogg/vorbis library is.

-Usage:
-
-Use message "vbr <samplerate> <channels> <quality>" to set the vorbis
-encoding parameters. Resampling is currently not supported, so 'samplerate'
-should be the one pd is running at. 'channels' specyfies the number of channels
-to stream. This can be set to 2 (default) or 1 which means mono stream taking
-the leftmost audio input only. 'quality' can be a value between 0.0 and 1.0
-giving the quality of the stream. 0.4 (default) results in a stream that's
-about 128kbps.
-
-Since Vorbis uses VBR encoding, bitrates vary depending on the type of audio
-signal to be encoded. A pure sine [osc~] results in the smalest stream, com-
-plex audio signals will increase this value significantly. To test the maximum
-bitrate that might occur for a quality setting use noise~ as signal input.
-
-Use message "vorbis <samplerate> <channels> <maximum bitrate> <nominal bit-
-rate> <minimal bitrate>" to set encoding quality on the basis of bitrates.
-When setting all three bitrate parameters to the same value one gets a
-constant bitrate stream. Values are in kbps!
-
-Message "connect <host> <mountpoint> <port>" connects to the IceCast2 server.
-Note that no response about succesfull connection is send by the server. All
-messages in the pd console window about connection status depend on the ability
-to send data to the server.
-The mountpoint should end with '.ogg' to indiocate to the player/client that
-it is an ogg/vorbis encoded stream.
-
-Use "passwd <passwort>" to set your password (default is 'letmein') and
-"disconnect" to disconnect from the server. "print" prints out the current
-vorbis encoder settings.
-
-To set the comment tags in the ogg/vorbis header (which can be displayed by
-the receiving client) use message "<NAMEOFTAG> <comment>". Supported tags are:
-TITLE, ARTIST, GENRE, PERFORMER, LOCATION, COPYRIGHT, CONTACT, DESCRIPTION and
-DATE (which is automatically set to the date/time the broadcast started). To
-get spaces use '=' or '_' instead. Note that under Win2k '=' sometimes get lost
-from the patch after saving!!!
-
-
-Listening to it:
-
-To listen to ogg/vorbis encoded livestreams many player need an extra plug-in.
-Have a look at http://www.vorbis.com/ to find the appropiate plug-in for your
-player.
-To play back the stream just open lacation http://<server>:<port>/<mountpoint>.
-
-Note that changing encoding parameters or header comments while oggcast~ is
-streaming to the server might result in audible dropouts.
