FLV::Info(3)	      User Contributed Perl Documentation	  FLV::Info(3)

NAME
       FLV::Info - Extract metadata from Adobe Flash Video files

SYNOPSIS
	   use FLV::Info;
	   my $reader =	FLV::Info->new();
	   $reader->parse('video.flv');
	   my %info = $reader->get_info();
	   print "$info{video_count} video frames\n";
	   print $reader->report();

DESCRIPTION
       This module reads Adobe Flash Video (FLV) files and reports metadata
       about those files.

LEGAL
       This work is based primarily on the file	specification provided by
       Adobe.  Use of that specification is governed by	terms indicated	at the
       licensing URL specified below.

       <http://www.adobe.com/devnet/flv/>

LICENSE
       Copyright 2006 Clotho Advanced Media, Inc., <cpan@clotho.com>

       Copyright 2007-2009 Chris Dolan,	<cdolan@cpan.org>

       This library is free software; you can redistribute it and/or modify it
       under the same terms as Perl itself.

METHODS
       $pkg->new()
	   Creates a new instance.

       $self->parse($filename)
       $self->parse($filehandle)
	   Reads the specified file.  If the file does not exist or is an
	   invalid FLV stream, an exception will be thrown via croak().

	   There is no return value.

       $self->get_info()
	   Returns a hash with all FLV metadata.  Any fields that are
	   multivalued are concatenated	with a slash ("/") with	the most
	   common values specified first.  For example,	a common case is the
	   "video_type"	which is often "interframe/keyframe" since interframes
	   are more common than	keyframes.  A less common case could be
	   "audio_type"	of "mono/stereo" if the	FLV was	mostly one-channel but
	   had some packets of two-channel audio.

       $self->report()
	   Returns a summary of	all FLV	metadata as a string.  This is a
	   human-readable version of the data returned by get_info().

       $self->get_file()
	   Returns the FLV::File instance.  This will be "undef" until you
	   call	parse().

SEE ALSO
       FLVTool2
	   This	is a rather nice Ruby implementation that can read and write
	   FLV files.  This code helped	me figure out that the FLV
	   documentation was wrong for the order of attributes in video	tags.
	   It also helped me understand	the meta tags.

	   <http://inlet-media.de/flvtool2>

       AMF::Perl
	   This	is a Perl implementation of the	<http://www.amfphp.org/>
	   project to create an	open source representation of the Flash	remote
	   communication protocol.  This module	leverages a small part of
	   AMF::Perl to	parse FLV meta tags.

       FFmpeg
	   FFmpeg is a powerful	media conversion utility.  It is capable of
	   reading and writing FLVs and	SWFs.  However as of this writing
	   (2006), I believe it	does not support fast transcoding between FLV
	   and SWF formats.  Please correct me if I'm mistaken.

	   <http://ffmpeg.mplayerhq.hu/>

COMPATIBILITY
       This module should work with FLV	v1.0 and FLV v1.1 files.  Any other
       versions	(none known as of this writing)	will certainly fail.

       Interaction with	FLVs using the screen video codec or using alpha
       channels	is not yet tested.  If someone has short videos	employing
       those features that can be released with	the FLV::Info test suite,
       please contact me.

       The AVC support comes from an external patch and	reading	documentation.
       I have not personally tested this code on any AVC FLV files.

AUTHOR
       Chris Dolan

       This module was originally developed by me at Clotho Advanced Media
       Inc. as part of our MediaLandscape project.  Now	I maintain it in my
       spare time.  I do not anticipate	adding new features without external
       input.

ACKNOWLEDGMENTS
       The FLV::Splice feature was created with	financial support from John
       Drago (CPAN:JOHND).  Thanks!

QUALITY
       I care about code quality.  The FLV-Info	distribution complies with the
       following quality metrics:

       o   Perl::Critic	v1.098 passes

       o   Devel::Cover	test coverage almost 90%

       o   Pod::Coverage at 100%

       o   Test::Spelling passes
