Stream::Reader is a stream reader Perl class.

SYNOPSIS

# Input stream can be reference to TYPEGLOB or SCALAR, output stream
# can be the same types or undefined

# Constructor
$stream = Stream::Reader->new( *IN,
{ Limit => $limit, BuffSize => $buffsize, Mode => UB } );

# Reading all before delimiter beginning from current position.
# Delimiter is SCALAR or reference to array with many SCALARs.
# Returns true value on succesfull matching or if end of stream
# expected at first time
$bool = $stream->readto( $delimiter,
{ Out => *OUT, Limit => $limit, Mode => AIE } );

# Reading fixed number of chars beginning from current position.
# Returns true value if was readed number of chars more then zero or
# end of stream was not expected yet
$bool = $stream->readsome( $limit, { Out => *OUT, Mode => A } );

# Mode is string, what can contains:
# U - modificator for constructor. disable utf-8 checking
# B - modificator for constructor. enable second buffer for speed up
# case insensitive search
# A - modificator for readto() and readsome(). appending data to
# output stream, if stream is SCALAR
# I - modificator for readto(). enable case insensitive search
# E - modificator for readto(). at end of input stream alltimes
# returns false value

$number = $stream->{Total}; # total number of readed chars
$number = $stream->{Readed}; # number of readed chars at last
# operation (without matched string
# length at readto() method)
$number = $stream->{Stored}; # number of succesfully stored chars
# at last operation
$string = $stream->{Match}; # matched string at last operation
# (actually for readto() only)
$bool = $stream->{Error}; # error status. true on error

METHODS

OBJ = Stream::Reader->new( INPUT, { ... Params ... } )

The constructor method instantiates a new Stream::Reader object.

INPUT - is a reference to file stream, opened for reading, or reference to defined string. This is an obligatory parameter.

Params (all optionaly):

Limit - limit size of input stream data in characters. If this parameter is absent, not defined or less then zero, then all data from input stream will be available for reading.

BuffSize - size of buffer in characters. If this parameter is absent, not defined or less then zero, then will be used default buffer size 32768 characters.

Mode - is string with letters-modificators:

B - use second buffer. Can really speed up search in case insensitive mode.
U - disable UTF-8 data check in UTF-8 mode. Use this flag if you are absolutely sure, that your UTF-8 data is valid.

RESULT = OBJ->readto( DELIMITER, { ... Params ... } )

This method reads all data from input stream before first found delimiter, beginning from current position.

RESULT - boolean value. True value if successfuly found delimeter or and of input stream has expected at first time. False value otherwise, or in case of reading error.

DELIMETER - is a string-delimeter or reference to array with many delimeters. This is an obligatory parameter and must be defined.

Remember! In case of many delimiters, left delimiter alltimes have more priority then right!

Params (all optionaly):

Out - is a reference to file stream, opened for writing, or reference to string. If this parameter is absent then data will not stored.
Limit - size in characters. Defines, the maximum number of characters that must be stored in Out. If this paramter is absent, not defined or less then zero, then this method will be trying to store all readed data.
Mode - is string with letters-modificators:
A - appendig data to Out if Out is a reference to string.
I - search in case insensitive mode.
E - at the end of input stream returns only false value. Without this modificator, if end of stream expected at first time, then will be returned true value.

RESULT = OBJ->readsome( LIMIT, { ... Params ... } )
This method reads fixed number of characters from input stream beginning from current position.

RESULT - boolean value. True value, if any characters were read or end of input stream is not expected yet. False value otherwise, or in case of reading error.

LIMIT - limit size in characters, how many it is necessary to read. If this parameter is absent, not defined or less then zero, then will be read all available data from input stream.

Params (all optionaly):

Out - the same as in readto() method.
Mode - is string with letters-modificators:
A - the same as in readto() method.

Statistics:

OBJ->{Total} - total number of readed characters. Warning! This module using block reading and real position in stream is different.
OBJ->{Readed} - number of readed characters at last operation (without matched string length at readto() method).
OBJ->{Stored} - number of succesfully stored chars at last operation
OBJ->{Match} - matched string at last operation (actually for readto() only)
OBJ->{Error} - boolen error status. At any reading erorrs all operations will be stopes and this flag turned to true value.

streamripagent is a simple Amarok script that watches the tracks streamed in Amarok. If any of the regexps in ~/.streamripagent matches the current title, streamripper is started and the track is ripped to a specified directory.

Its not exactly an amarok script that you can manage with the amarok script manager, but its related to amarok, so I put it in this category.

Please read the README before installing and running streamripagent!

MuSE is a user-friendly tool for network audio streaming.
MuSE provides the free software community with a user friendly but powerful tool for network audio streaming, making life easier for indypendent free speech online radios.
MuSE is an application for the mixing, encoding, and network streaming of sound: it can mix up to 6 encoded audio bitstreams (from files or network, mp3 or ogg) plus a souncard input signal, the resulting stream can be played locally on the sound card and/or encoded at different bitrates, recorded to harddisk and/or streamed to the net.
When sent to a server, the resulting audio can be listened thru the net by a vast number of players available on different operating systems.
To be operated MuSE offers graphical interfaces and a documented commandline interface in the good old unix style.
Main features:
- Mixes up to 6 channels + 1 soundcard input channel simultaniously
- decodes and mixes both ogg and mp3, from files or network streams
- encodes at different bitrates and sends multiple mp3 or ogg streams to icecast, shoutcast and darwin servers.
- offers two different intuitive user interfaces and a documented command line interface
- play, stop, pause/resume, position and volume for each channel, looping thru playlists and reconnecting automatically to lost server connections
- efficient multithreaded architecture with emphasys on performance to support older CPUs
- reusable API interface to the core mixing engine permits to adapt new interfaces

FFmpeg::Stream is an audio or video stream from a (multi)media file.

SYNOPSIS

$ff = FFmpeg->new(); #see FFmpeg
#...
$sg = $ff->create_streamgroup(); #see FFmpeg
$st = ($sg->streams())[0]; #this is a FFmpeg::Stream

FFmpeg::Stream objects are not instantiated. Rather, objects are instantiated from FFmpeg::Streams subclasses FFmpeg::Stream::Video for video streams, FFmpeg::Stream::Audio for audio streams, and FFmpeg::Stream::Data for streams containing neither audio nor video data. Streams identified in the file whose content type cannot be determined are represented by FFmpeg::Stream::Unknown objects.

Access FFmpeg::Stream objects using methods in FFmpeg::StreamGroup. See FFmpeg::StreamGroup for more information.

This class has attributes applicable to any stream type in a multimedia stream, or stream group. FFmpeg-Perl represents multimedia stream group information in a FFmpeg::StreamGroup object, which is a composite of FFmpeg::Stream objects.

FFmpeg::Stream objects dont do much. They just keep track of the media streams ID within the multimedia stream group, and hold an instance to a FFmpeg::Codec object if the codec of the stream was deducible. See FFmpeg::Codec for more information about how codecs are represented.

wmstradio is a doc app that acts as a radio for streamed media. It reads a list of "channels" and allows them to be selected in a radio like interface. wmstradio launches Real Player connecting to the site that you select.
The only configuring wmstradio needs is a list of RealAudio sites to connect to. This is provided through a directory called ~/.wmstradio which contains link files to the sites. These link files are what you get when you try to save the link through a web browser. They are text files containing a URL to the server real audio streamer. The name of this file is used as the name of the chanel in the wmstradio display window.
Enhancements:
- BUGFIX: shaifuljahari at yahoo.com pointed out that an empty .wmstradio directory caused the app to core on load. Fixed.
- MISC: Empty directories are now detected at load, and during the lifetime of the app. Appropriate error message given on standard error and lcd.
- DOCUMENTATION: CREDITS added.

FFmpeg::Stream::Video is a video stream from a (multi)media stream group.

SYNOPSIS

$ff = FFmpeg->new(); #see FFmpeg
#...
$sg = $ff->create_streamgroup(); #see FFmpeg
$st = ($sg->streams())[0]; #this is a FFmpeg::Stream

Objects of this class are not intended to be instantiated directly by the end user. Access FFmpeg::Stream::Video objects using methods in FFmpeg::StreamGroup. See FFmpeg::StreamGroup for more information.

This class represents a video stream in a multimedia stream group. General stream attributes can be found in the FFmpeg::Stream class.
