Free stream software for linux

Stream-2-Stream project (abbreviated "s2s" or "S2S") allows anyone with a normal broadband connection to set up their own radio station or internet television, for free.
Stream-2-Stream stations have no user limit; stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another, rather than everyone getting a stream from one central server (Shoutcast/Icecast).
Supported codecs are MP3, NSV, and Ogg Vorbis.
Main features:
- Integrated MP3, Ogg media player. No external media player needed to listen!!!
- Easy to use GUI
- Bandwidth is tested automatically for the best p2p streaming performance
- Settings are saved to xml
- Easy to use server command-line
- A shoutcast/icecast internet radio/TV Station is used as the source
- Freeloaders/Leechers (peers that only listen but dont want to send out the stream to other listeners) will be detected
- The data stream can be signed; you can be sure that it arrives unchanged
- Very efficient communication (low overhead).
- The network structure can be viewed with a monitor
- Peers can be denied service
- Streams can be recorded to files for later viewing
Enhancements:
- s2s protocol version 3 provides streaming through TCP, UDP, and Multicast+.
- The number of listeners can be seen.
- GUI mechanics fixed
- Connecting improved
- LanPages changed to multicast
- Player and Web ports switched for easy port forwarding.
- Public player connections can now be toggled in the options menu.
- Xml file can be specified with the arg -x file.xml

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.

Audio::Mad::Stream is a Perl interface to mad_stream structure.

SYPNOSIS

my $stream = new Audio::Mad::Stream ($options);
$stream->buffer($scalar);

my $remain = substr($scalar, $stream->next_frame);
my $position = $stream->this_frame;

$stream->skip($position + 400);
$stream->sync();

$options = $stream->options();
$options |= MAD_OPTION_IGNORECRC;
$stream->options($options);

unless ($stream->err_ok()) {
print "error code was: " . $stream->error() . "n";
}

This package provides an interface to the underlying mad_stream structure used in the decoder library. Almost all of the methods from the library are implemented, and work on regualar perl data types.

FFmpeg::Stream::Audio is an audio 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::Audio objects using methods in FFmpeg::StreamGroup. See FFmpeg::StreamGroup for more information.

This class represents an audio stream in a multimedia stream group, and has audio-specific attributes. General stream attributes can be found in the FFmpeg::Stream class.

XML::Parser::Style::Stream is a Stream style for XML::Parser.

SYNOPSIS

use XML::Parser;
my $p = XML::Parser->new(Style => Stream, Pkg => MySubs);
$p->parsefile(foo.xml);

{
package MySubs;

sub StartTag {
my ($e, $name) = @_;
# do something with start tags
}

sub EndTag {
my ($e, $name) = @_;
# do something with end tags
}

sub Characters {
my ($e, $data) = @_;
# do something with text nodes
}
}

This style uses the Pkg option to find subs in a given package to call for each event. If none of the subs that this style looks for is there, then the effect of parsing with this style is to print a canonical copy of the document without comments or declarations. All the subs receive as their 1st parameter the Expat instance for the document theyre parsing.

It looks for the following routines:

StartDocument

Called at the start of the parse .

StartTag

Called for every start tag with a second parameter of the element type. The $_ variable will contain a copy of the tag and the %_ variable will contain attribute values supplied for that element.

EndTag

Called for every end tag with a second parameter of the element type. The $_ variable will contain a copy of the end tag.

Text

Called just before start or end tags with accumulated non-markup text in the $_ variable.

PI

Called for processing instructions. The $_ variable will contain a copy of the PI and the target and data are sent as 2nd and 3rd parameters respectively.

EndDocument

Called at conclusion of the parse.
