Re^3: explore a complexe hash structure return by Webservices::GData::YouTube

[Anonymous Monk]

So you're using http://search.cpan.org/perldoc/WebService::GData::YouTube#search_video which returns a WebService::GData::YouTube::Feed::Video which says in SYNOPSIS to use

    foreach my $video (@$videos) {
        say $video->video_id;
        say $video->title;
        say $video->content;
        say $video->view_count;
        say $video->favorite_count;
        say $video->duration;
    }

You're after thumbnails and there is a http://search.cpan.org/perldoc/WebService::GData::YouTube::Feed::Video#thumbnails

A grep thumbnails returns

lib/WebService/GData/YouTube/Doc/GeneralOverview.pod

254:           my $thumbs =$video->thumbnails;

lib/WebService/GData/YouTube/Feed/Video.pm

158:sub thumbnails {
633:=head3 thumbnails

t/56-WebService-GData-YouTube-Feed-Video-instance.t

91:ok( @{ $entry->thumbnails } == 5, 'number of thumbnails is right.' 
+);
93:ok($entry->thumbnails->[0]->url eq 'http://i.ytimg.com/vi/qWAY3YvHq
+LE/default.jpg','thumbnail is properly set.');

So thumbnails returns a list, and there is an example of usage in WebService::GData::YouTube::Doc::GeneralOverview , a sub display_video which contains

           my $thumbs =$video->thumbnails;
           foreach my $thumb (@$thumbs) {
                say $thumb->url;
                say $thumb->time;
                say $thumb->width;
                say $thumb->height;
           }

So there you go

    $yt->query()->q( $query )->limit( 10, 2 );
    $yt->query()->maxresults( 20 );
    my $videos = $yt->search_video();

    display_videos( $videos );

    my $videos = shift;
