Ogg Video Tools 0.6 (Default branch)
The Ogg Video Tools is a toolbox for manipulating Ogg video files, which usually consist of a video stream (Theora) and an audio stream (Vorbis). It includes a number of handy command line tools for manipulating these video files, such as for splitting the different streams. License: GNU General Public License (GPL) Changes:
This release offers two new command line tools. The first is oggSlideshow, which creates a video slideshow from a number of given images, e.g. with the Ken Burns Effect. The second is oggThumb, which creates thumbnail images from a Theora video stream. There are additional changes like support for kate streams, handling of files beyond 4 GB in size, and some minor bugfixes. Image

ogg::vorbis::header::pureperl

PurePerl(3pm)						User Contributed Perl Documentation					     PurePerl(3pm)

NAME

       Ogg::Vorbis::Header::PurePerl - An object-oriented interface to Ogg Vorbis information and comment fields, implemented entirely in Perl.
       Intended to be a drop in replacement for Ogg::Vobis::Header.

       Unlike Ogg::Vorbis::Header, this module will go ahead and fill in all of the information fields as soon as you construct the object.  In
       other words, the "new" and "load" constructors have identical behavior.

SYNOPSIS

	       use Ogg::Vorbis::Header::PurePerl;
	       my $ogg = Ogg::Vorbis::Header::PurePerl->new("song.ogg");
	       while (my ($k, $v) = each %{$ogg->info}) {
		       print "$k: $v
";
	       }
	       foreach my $com ($ogg->comment_tags) {
		       print "$com: $_
" foreach $ogg->comment($com);
	       }

DESCRIPTION

       This module is intended to be a drop in replacement for Ogg::Vorbis::Header, implemented entirely in Perl.  It provides an object-oriented
       interface to Ogg Vorbis information and comment fields.	(NOTE: This module currently supports only read operations).

CONSTRUCTORS

   "new ($filename)"
       Opens an Ogg Vorbis file, ensuring that it exists and is actually an Ogg Vorbis stream.	This method does not actually read any of the
       information or comment fields, and closes the file immediately.

   "load ([$filename])"
       Opens an Ogg Vorbis file, ensuring that it exists and is actually an Ogg Vorbis stream, then loads the information and comment fields.
       This method can also be used without a filename to load the information and fields of an already constructed instance.

INSTANCE METHODS

   "info ([$key])"
       Returns a hashref containing information about the Ogg Vorbis file from the file's information header.  Hash fields are: version, channels,
       rate, bitrate_upper, bitrate_nominal, bitrate_lower, bitrate_window, and length.  The bitrate_window value is not currently used by the
       vorbis codec, and will always be -1.

       The optional parameter, key, allows you to retrieve a single value from the object's hash.  Returns "undef" if the key is not found.

   "comment_tags ()"
       Returns an array containing the key values for the comment fields.  These values can then be passed to "comment" to retrieve their values.

   "comment ($key)"
       Returns an array of comment values associated with the given key.

   "add_comments ($key, $value, [$key, $value, ...])"
       Unimplemented.

   "edit_comment ($key, $value, [$num])"
       Unimplemented.

   "delete_comment ($key, [$num])"
       Unimplemented.

   "clear_comments ([@keys])"
       Unimplemented.

   "write_vorbis ()"
       Unimplemented.

   "path ()"
       Returns the path/filename of the file the object represents.
