App::Info is Perl module information about software packages on a system.

SYNOPSIS

use App::Info::Category::FooApp;

my $app = App::Info::Category::FooApp->new;

if ($app->installed) {
print "App name: ", $app->name, "n";
print "Version: ", $app->version, "n";
print "Bin dir: ", $app->bin_dir, "n";
} else {
print "App not installed on your system. :-(n";
}

App::Info is an abstract base class designed to provide a generalized interface for subclasses that provide metadata about software packages installed on a system. The idea is that these classes can be used in Perl application installers in order to determine whether software dependencies have been fulfilled, and to get necessary metadata about those software packages.

App::Info provides an event model for handling events triggered by App::Info subclasses. The events are classified as "info", "error", "unknown", and "confirm" events, and multiple handlers may be specified to handle any or all of these event types. This allows App::Info clients to flexibly handle events in any way they deem necessary. Implementing new event handlers is straight-forward, and use the triggering of events by App::Info subclasses is likewise kept easy-to-use.

A few sample subclasses are provided with the distribution, but others are invited to write their own subclasses and contribute them to the CPAN. Contributors are welcome to extend their subclasses to provide more information relevant to the application for which data is to be provided (see App::Info::HTTPD::Apache for an example), but are encouraged to, at a minimum, implement the abstract methods defined here and in the category abstract base classes (e.g., App::Info::HTTPD and App::Info::Lib). See Subclassing for more information on implementing new subclasses.

SYNOPSIS

my $mi = Movie::Info->new || die "Couldnt find an mplayer to usen";

foreach my $file (@ARGV) {
my %info = $mi->info($file) || warn "Couldnt read info from $filen" && next;
print "$file (WxH) - $info{width}x$info{height}n";

}

Movie::Info is a thin layer around MPlayers --identify command line flag. As such it can only give you as much information as Mplayer is able to give you which is down to the quality and number of codecs you have installed.
MPlayer is available from http://www.mplayerhq.hu/

This module is largely based on the midentify script shipped with MPlayer.

METHODS

new [path to mplayer]

Returns a new Movie::Info instance or undef if it cant find an mplayer binary.
To find a binary it looks in three places - firstly if youve passed in a path to look at it checks there, secondly at the environment variable $MOVIE_INFO_MPLAYER_PATH and then finally it searches your $PATH like the standard which command in Unix.

info < filename >

Returns a hash representing all the meta data we can garner about file.
Returns undef if it cant read the file.

City info search enables you to get all the information about any city in the USA with a mouse click.

Get all the information about any city in the USA with a mouse click. This includes geography, population, ethnic composition, housing, climate, hospitals, airports, etc.

Usage: highlight the name on any US city on a page. Right click the mouse. Choose Get City Info.

No annoing toolbars.

Pin is package info searches the System (rpm -pi, -ql) and the SuSE table of contents file from the CD for a item.

The table of contents file is on the first SuSE CD (ARCHIVES.gz)

MP3::Info is a Perl module that can manipulate / fetch info from MP3 audio files.

SYNOPSIS

#!perl -w
use MP3::Info;
my $file = Pearls_Before_Swine.mp3;
set_mp3tag($file, Pearls Before Swine, q"77s",
Sticks and Stones, 1990,
q"(c) 1990 77s LTD.", rock & roll);

my $tag = get_mp3tag($file) or die "No TAG info";
$tag->{GENRE} = rock;
set_mp3tag($file, $tag);

my $info = get_mp3info($file);
printf "$file length is %d:%dn", $info->{MM}, $info->{SS};
my $mp3 = new MP3::Info $file;
$mp3->title(Perls Before Swine);
printf "$file length is %s, title is %sn",
$mp3->time, $mp3->title;

$mp3 = MP3::Info->new(FILE)

OOP interface to the rest of the module. The same keys available via get_mp3info and get_mp3tag are available via the returned object (using upper case or lower case; but note that all-caps "VERSION" will return the module version, not the MP3 version).

Passing a value to one of the methods will set the value for that tag in the MP3 file, if applicable.

use_mp3_utf8([STATUS])

Tells MP3::Info to (or not) return TAG info in UTF-8. TRUE is 1, FALSE is 0. Default is TRUE, if available.

Will only be able to turn it on if Encode is available. ID3v2 tags will be converted to UTF-8 according to the encoding specified in each tag; ID3v1 tags will be assumed Latin-1 and converted to UTF-8.

Function returns status (TRUE/FALSE). If no argument is supplied, or an unaccepted argument is supplied, function merely returns status.

This function is not exported by default, but may be exported with the :utf8 or :all export tag.

use_winamp_genres()

Puts WinAmp genres into @mp3_genres and %mp3_genres (adds 68 additional genres to the default list of 80). This is a separate function because these are non-standard genres, but they are included because they are widely used.

You can import the data structures with one of:
use MP3::Info qw(:genres);
use MP3::Info qw(:DEFAULT :genres);
use MP3::Info qw(:all);

remove_mp3tag (FILE [, VERSION, BUFFER])

Can remove ID3v1 or ID3v2 tags. VERSION should be 1 for ID3v1 (the default), 2 for ID3v2, and ALL for both.

For ID3v1, removes last 128 bytes from file if those last 128 bytes begin with the text TAG. File will be 128 bytes shorter.

For ID3v2, removes ID3v2 tag. Because an ID3v2 tag is at the beginning of the file, we rewrite the file after removing the tag data. The buffer for rewriting the file is 4MB. BUFFER (in bytes) ca change the buffer size.

Returns the number of bytes removed, or -1 if no tag removed, or undef if there is an error.

set_mp3tag (FILE, TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE [, TRACKNUM])

set_mp3tag (FILE, $HASHREF)

Adds/changes tag information in an MP3 audio file. Will clobber any existing information in file.

Fields are TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE. All fields have a 30-byte limit, except for YEAR, which has a four-byte limit, and GENRE, which is one byte in the file. The GENRE passed in the function is a case-insensitive text string representing a genre found in @mp3_genres.

Will accept either a list of values, or a hashref of the type returned by get_mp3tag.
If TRACKNUM is present (for ID3v1.1), then the COMMENT field can only be 28 bytes.

ID3v2 support may come eventually. Note that if you set a tag on a file with ID3v2, the set tag will be for ID3v1[.1] only, and if you call get_mp3tag on the file, it will show you the (unchanged) ID3v2 tags, unless you specify ID3v1.

get_mp3tag (FILE [, VERSION, RAW_V2])

Returns hash reference containing tag information in MP3 file. The keys returned are the same as those supplied for set_mp3tag, except in the case of RAW_V2 being set.
If VERSION is 1, the information is taken from the ID3v1 tag (if present). If VERSION is 2, the information is taken from the ID3v2 tag (if present). If VERSION is not supplied, or is false, the ID3v1 tag is read if present, and then, if present, the ID3v2 tag information will override any existing ID3v1 tag info.

If RAW_V2 is 1, the raw ID3v2 tag data is returned, without any manipulation of text encoding. The key name is the same as the frame ID (ID to name mappings are in the global %v2_tag_names).

If RAW_V2 is 2, the ID3v2 tag data is returned, manipulating for Unicode if necessary, etc. It also takes multiple values for a given key (such as comments) and puts them in an arrayref.

If the ID3v2 version is older than ID3v2.2.0 or newer than ID3v2.4.0, it will not be read.

Strings returned will be in Latin-1, unless UTF-8 is specified (use_mp3_utf8), (unless RAW_V2 is 1).

Also returns a TAGVERSION key, containing the ID3 version used for the returned data (if TAGVERSION argument is 0, may contain two versions).
get_mp3info (FILE)

Returns hash reference containing file information for MP3 file. This data cannot be changed. Returned data:

VERSION MPEG audio version (1, 2, 2.5)
LAYER MPEG layer description (1, 2, 3)
STEREO boolean for audio is in stereo

VBR boolean for variable bitrate
BITRATE bitrate in kbps (average for VBR files)
FREQUENCY frequency in kHz
SIZE bytes in audio stream
OFFSET bytes offset that stream begins

SECS total seconds
MM minutes
SS leftover seconds
MS leftover milliseconds
TIME time in MM:SS

COPYRIGHT boolean for audio is copyrighted
PADDING boolean for MP3 frames are padded
MODE channel mode (0 = stereo, 1 = joint stereo,
2 = dual channel, 3 = single channel)
FRAMES approximate number of frames
FRAME_LENGTH approximate length of a frame
VBR_SCALE VBR scale from VBR header
On error, returns nothing and sets $@.

print $file->achans; ## 1
print $file->arate; ## 128000 (bits/sec)
print $file->astreams ## 1

## Video information
printf "%0.2f", $file->fps ## 29.97
print $file->height ## 240
print $file->width ## 352

print $file->vcodec ## MPEG1
print $file->vframes ## 529
print $file->vrate ## 1000000 (bits/sec)

The Moving Picture Experts Group (MPEG) is a working group in charge of the development of standards for coded representation of digital audio and video.
MPEG audio and video clips are ubiquitous but using Perl to programmatically collect information about these bitstreams has to date been a kludge at best.

This module parses the raw bitstreams and extracts information from the packet headers. It supports Audio, Video, and System (multiplexed audio and video) packets so it can be used on nearly every MPEG you encounter.
