Fatal error: Call to a member function attributes() on a non-object when unsupported type of feed is provided

Please, could you post us the URL of the feed which are you trying to parse? Thanks

But this is a bug anyway, maybe we didn't consider all possible types of youtube feeds and also we didn't implemented any validation, that you are trying parse wrong feed yet... and we should.

@Toxid: We have already link to this tool in the project description, I'm going to place it to the top, to make it more visible.

Currently this module supports Programmatic access projection for YouTube feeds. See the YouTube API index. Supports both types of possible RSS feeds: Atom or RSS2.0.

Can anyone please post a working feed URL, I keep getting this error and I'm using the Interactive YouTube API Demo

Edit: I'm using this URL and it's not working:

http://gdata.youtube.com/feeds/base/videos?alt=rss&q=drupal&orderby=published&format=5

thanks, I'll try it

Same Error here .. and here is my URL:

http://gdata.youtube.com/feeds/base/videos?max-results=5&alt=rss&orderby=published&author=NBAHiighlights

and same error with another URL:

http://gdata.youtube.com/feeds/base/users/NBA/uploads?alt=rss

@ezfranca: Please, read the module instructions, you are using base URL not API url.

Try this one: http://gdata.youtube.com/feeds/api/videos?author=NBA

Ok, I read it and try it with another URL: http://gdata.youtube.com/feeds/api/users/NBA/uploads?alt=rss

Now, I have the description, but I still do not have the video. I want the each feed entry with the embedded video and not only the text part with a link to youtube. There is a way to do this ? Thank you in advance.

@ezfranca You need the Media field http://drupal.org/project/media for Drupal 7 or http://drupal.org/project/emfield for Drupal 6.

There should be an exception handler to display more friendly message + *document* how to use it in README file.

I am having the same problem and also tried this url: http://gdata.youtube.com/feeds/api/videos?author=NBA
Still no luck

#13 @good_man yeah, exception handler would be nice. However we are dealing with the fatal error... anyway probably the best way how to get rid of these errors will be FeedsYoutubeHttpFetcher, which could validate the URL and prevents to run the parser if the URL will not match against supported pattern, because parser gets only raw data from Feeds and it doesn't have access to the URL from which the data was fetched. Or aternatively we need to develop some fingerprinting methods to detect with what type of feed we are dealing with before we start to parse it.

#14 @Mozzy 7.x-2.x-dev should be working now for this URL.

What configuration is being used here?

Like what kind of a field, which Widget is applied to the field, and then how is that mapped in the "Mapping" area of the parser? I can get the video description, but that is all. The "api"-style link has really helped, but the video itself is still elusive.

EDIT: see this post http://drupal.org/node/1358558

I to ran into this error. Updating the feed url changed the error, but didnt fix the problem. Note: running the latest Feeds -dev branch. So i went from the above stated error message. Switched the feed to http://gdata.youtube.com/feeds/api/videos?author=IMAItsMyArt and now i get the following error message

Service unavailable (with message) ResponseText: Recoverable fatal error: Argument 2 passed to FeedsProcessor::process() must be an instance of FeedsParserResult, null given, called in /var/www/artbabble/drupal/sites/all/modules/feeds/includes/FeedsSource.inc on line 357 and defined in FeedsProcessor->process() (line 105 of /var/www/artbabble/drupal/sites/all/modules/feeds/plugins/FeedsProcessor.inc).

The URL that worked for me was:

http://gdata.youtube.com/feeds/api/videos?author=NBA&alt=rss

But it filled no media youtube fields, just copied the titles.

The users I'm creating a project for will need to add individual YouTube feeds, but are not technical enough to use the YouTube API tool to locate feed URLs. (Indeed, they aren't technical enough to do more than copy and paste the page URL from a YouTube page...) So, we needed a more automatic solution. The attached patch adds a fetcher plugin that extends FeedsHTTPFetcher to correct YouTube feed URLs after they are auto-detected. If the auto-detect checkbox is not selected, the URL will not be modified in any way, so users may still choose the exact URL they need.

I had a similiar need as #19 and wrote a custom solution. sharing incase someone else finds this useful

define('FEEDS_YOUTUBE_URL', 'http://gdata.youtube.com/feeds/api/videos?v=2&author=');

function artbabble_form_institution_node_form_alter(&$form, &$form_state) {
    // The feeds_youtube module requires a specific feed to work properly.  So only
    // require the user to enter the user name and we will take care of the rest.
    $form['feeds']['FeedsHTTPFetcher']['source']['#required'] = FALSE;
    $form['feeds']['FeedsHTTPFetcher']['source']['#title'] = t('YouTube Username');
    $form['feeds']['FeedsHTTPFetcher']['source']['#description'] = t('Enter institutions YouTube username');
    $form['feeds']['FeedsHTTPFetcher']['source']['#default_value'] = parse_feeds_remove_url($form['feeds']['FeedsHTTPFetcher']['source']['#default_value']);
    array_unshift($form['#validate'], 'artbabble_form_institution_node_form_validate');
}

function artbabble_form_institution_node_form_validate(&$form, &$form_state) {
    $form_state['values']['feeds']['FeedsHTTPFetcher']['source'] = parse_feeds_add_url($form_state['values']['feeds']['FeedsHTTPFetcher']['source']);
}

function parse_feeds_remove_url($url, $link = FEEDS_YOUTUBE_URL) {
    return str_replace($link, '', $url);
}

function parse_feeds_add_url($url, $link = FEEDS_YOUTUBE_URL) {
    return $link . $url;
}

My URL works (kinda). It imports videos but the descriptions are trimmed to a max length and it only imports 25 videos max... It seems as if its hitting a paged feed that trims the descriptions (even adding elipsis) and is paged to 25 results. Any idea how to avoid this? This is the URL: http://gdata.youtube.com/feeds/api/videos?author=cangrejerossanturce&alt...

Same here.

I have Youtube URLs with the exact same syntax running without any problems. One special URL throws this error.
They are all Playlist URLs

http://gdata.youtube.com/feeds/api/playlists/...
