File::Format::RIFF is a Perl module to Resource Interchange File Format/RIFF files.

SYNOPSIS

use File::Format::RIFF;

open( IN, file ) or die "Could not open file: $!";
my ( $riff1 ) = File::Format::RIFF->read( *IN );
close( IN );
$riff1->dump;

my ( $riff2 ) = new File::Format::RIFF( TYPE );
foreach my $chunk ( $riff1->data )
{
next if ( $chunk->id eq LIST );
$riff2->addChunk( $chunk->id, $chunk->data );
}
open( OUT, ">otherfile" ) or die "Could not open file: $!";
$riff2->write( *OUT );
close( OUT );

File::Format::RIFF provides an implementation of the Resource Interchange File Format. You can read, manipulate, and write RIFF files.

CONSTRUCTORS

$riff = new File::Format::RIFF( $type, $data );

Creates a new File::Format::RIFF object. $type is a four character code that identifies the type of this particular RIFF file. Certain types are defined to have a format, specifying which chunks must appear (e.g., WAVE files). If $type is not specified, it defaults to (four spaces). $data must be an array reference containing some number of RIFF lists and/or RIFF chunks. If $data is undef or not specified, then the new RIFF object is initialized empty.

$riff = File::Format::RIFF->read( $fh, $filesize );

Reads and parses an existing RIFF file from the given filehandle $fh. An exception will be thrown if the file is not a valid RIFF file. $filesize controls one aspect of the file format checking -- if $filesize is not specified, then stat will be called on $fh to determine how much data to expect. You may explicitly specify how much data to expect by passing in that value as $filesize. In either case, the amount of data read will be checked to make sure it matches the amount expected. Otherwise, it will throw an exception. If you do not wish it to make this check, pass in undef for $filesize.

Please note, if you wish to read an "in memory" filehandle, such as by doing this: open( $fh, read( $fh, $filesize );

The read constructor may also be used as a method. If used in this manner, then all existing data contained in $riff will be discarded, and replaced by the contents read from $fh.

$riff->write( $fh );

Outputs a properly-formatted RIFF file to the given filehandle $fh.

Format on Save is a Eclipse plugin to automatically organizes imports and formats code when saving a Java editor.

This is the exact equivalent as doing Ctrl-Shift-O, Ctrl-Shift-F before saving. New features: - Sort Members and Correct Indentation - preference page to configure defaults

File2Divx3Pass is a Perl-GTK frontend to mencoder for encoding media file to MPEG4.

It can encode any media file supported by mencoder to DiVX, in 1-, 2- or 3-pass encoding.

You can create new, save and load projects and you can batch encode your projects. It also has an automatic video bitrate and bits per pixel calculator.

File2DiVX3Pass2 is a Gtk2 version, with the same functionality as the Gtk version. I have added some new features (see changelog). Formats tested by me that work: MPEG-1, MPEG-2, DiVX, WMV, ASF, RM, MOV, DAT, CUE/BIN and OGM.

The Audio File Library provides a uniform and elegant API for accessing a variety of audio file formats, such as AIFF/AIFF-C, WAVE, NeXT/Sun .snd/.au, Berkeley/IRCAM/CARL Sound File, Audio Visual Research, Amiga IFF/8SVX, and NIST SPHERE. Supported compression formats are currently G.711 mu-law and A-law and IMA and MS ADPCM.

Key goals of the Audio File Library are file format transparency and data format transparency. The same calls for opening a file, accessing and manipulating audio metadata (e.g. sample rate, sample format, textual information, MIDI parameters), and reading/writing sample data will work with any supported audio file format. Likewise, the format of the audio data presented to the application need not be tied to the format of the data contained in the file.

Image::ExifTool::MPEG is a Perl module to read MPEG-1 and MPEG-2 meta information.

SYNOPSIS

This module is used by Image::ExifTool

This module contains definitions required by Image::ExifTool to read MPEG-1 and MPEG-2 audio/video files.

NOTES

Since ISO charges money for the official MPEG specification, this module is based on unofficial sources which may be incomplete, inaccurate or outdated.

Video::Info::Magic can resolve video filetype if possible.

SYNOPSIS

use strict;
use Video::Info::Magic qw(:all);

my $type = divine(/path/to/video.mpg );

print $type; #MPEG system stream data (maybe)

## ... see methods below

EXPORT

various constants related to video file formats. All are prefixed with "VIDEO_".
divine(): Employs /usr/share/magic entries to determine a files type, as well as GUID and other info from Microsoft, mplayer, transcode...

Video::Info::MPEG::System is a suite of modules to probe video files for various attributes.

Previous versions of Video::Info depended on external modules, such as RIFF::Info and ASF::Info. This is no longer the case, you dont need to install them. All the functionality is now included with the Video::Info distribution.

To contribute, use Video::Info::FOO as a template to write a module, and email it to the Allen Day. Also see t/FOO.t as an example test script to verify the sanity of your code.

Installation:

To install this module type the following:

perl Makefile.PL
make
make test (optional)
make install
