NAME
XML::FeedPP::MediaRSS - MediaRSS support for XML::FeedPP
VERSION
version 0.02
SYNOPSIS
use XML::FeedPP;
my $feed = XML::FeedPP->new('http://a.media.rss/source');
my $media = XML::FeedPP::MediaRSS->new($feed);
for my $i ( $feed->get_item ) {
for my $content ( $media->for_item($i) ) {
die "18 or over" if $content->{adult};
}
}
DESCRIPTION
XML::FeedPP does not support Yahoo's MediaRSS extension, and it shouldn't. It's only
supported in some formats, and XML::FeedPP is a lowest-common-denominator kind of module.
That said, sometimes you need to consume feeds with MediaRSS in them.
METHODS
new ( feed )
You have to pass in an XML::FeedPP object. "XML::FeedPP::MediaRSS" isn't a subclass of
XML::FeedPP - it has one, and inspects its dirty innards (which is somewhat safe since
they're produced by XML::TreePP) to find media content.
for_item ( item )
Pass in a feed item (the things returned by "$feed->get_item") and get back a list of
"XML::FeedPP::MediaRSS::Content" objects.
KEYS
adult
1 or ''
rating
A hash of all the ratings found, schema => rating.
title
A hash of all titles found, type => value.
keywords
An arrayref of all the keywords found. The comma-delimiting is undone and duplicates are
removed.
thumbnails
All thumnails found, from most specific (deepest) to least specific. This means that if
the channel has a thumbnail and the item has a thumbnail, you'll get the item first, then
the channel. If there are multiple thumbnails at the same level, you'll get them in
document order. Time coding is not considered. They look like this:
{ url => '...', width => 400, height => 300, time => 'timecode' }
category
Hash of scheme => plain contents of tag
hash
Deepest only.
{
algorithm => 'md5',
checksum => 'dfdec888b72151965a34b4b59031290a',
}
player
Deepest only.
{
url => '...',
height => 300,
width => 400
}
credit
Hash of scheme to role-hash, like this:
{
'urn:ebu' => {
actor => [
'Julia Roberts',
'Tom Hanks',
],
director => [
'Stevan Spielberg',
]
}
}
copyright
Deepest only.
{ url => '...', text => '2005 Foobar Media' }
text
A list of text objects in document order, like this:
[
{
type => 'plain',
lang => 'en',
start => 'timecode',
end => 'timecode',
text => 'The actual value',
},
]
restriction
{
allow => (1|0),
type => (country|uri|sharing)
list => [ ... ] | 'all' | 'none'
}
If allow is false, that means deny.
community
Deepest only.
{
starRating => {
average => 3.5,
count => 20,
min => 1,
max => 10,
},
statistics => {
views => 5,
favorites => 5,
},
tags => {
news => 5,
abc => 3,
reuters => undef,
},
}
comments
Simple list of strings.
embed
Hash of key-value pairs. Deepest only.
responses
Simple list of strings
backlinks
Simple list of strings
status
Deepest only.
{ state => 'status', reason => 'reason' }
price
List of pricing structures, which are hashes with the keys "currency" (optional), "info"
(optional), "type" (optional), and "price" (optional). If none of these is present for a
given price tag, we're going to pretend it doesn't exist.
license
Hash of type, href, and name. Deepest only.
subTitle
Only one per language as per the spec.
{
'en_us' => {
href => 'http://www.example.org/subtitle.smil',
type => 'application/smil',
}
}
peerLink
Deepest only, hash of type and href.
location
NOT SUPPORTED, mostly cause I don't need it and I don't feel like reading the geoRSS spec
right now. Patches welcome!
rights
value of the status attribute for the deepest rights element.
scenes
Deepest only, list of hashes with keys title, description, start_time, and end_time.
ALPHA
This software hasn't yet been tested beyond the examples provided in the mRSS spec.
Failing tests (even better, with patches that fix the failures) are very welcome! Fork and
send a pull request on "GITHUB".
XML::FeedPP::MediaRSS::Content
These are blessed hashes, but you're allowed to look inside them. In fact, you're really
supposed to. It's okay, don't be nervous.
The mapping from the MediaRSS spec (<http://video.search.yahoo.com/mrss>) to this hash is
really straightforward. See the "KEYS" section for more detail. The shallowness-rules
talked about in the spec are applied, e.g. specifiers at higher levels are applied to
lower level objects unless they have a more specific rule.
LIMITATIONS
Groups
You don't have to (get to?) deal with media groups. All the content for an item gets
flattened into one list. Future versions of this module may add support for media groups
under a different method name ("groups_for_item") if anyone ever sends me a patch or I can
ever find an actual use for it.
Order
The MediaRSS spec says some things about order being dependent on document order. We go by
the order we get things from XML::FeedPP's hashes, which will only be the same as document
order if you "use_ixhash => 1" in the feed. And even then, content in media:groups will
come before content outside them.
Read-Write
This module only supports reading MediaRSS information from a feed, not adding it. I might
add this someday, but of course patches are welcome in the meantime.
