RSS media:content is not available for items in Flickr RSS feed

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Load a flickr RSS feed

     myfeed = feed.feedparse( 'http://api.flickr.com/services/feeds/photos_public.gne?tags=architecture&lang=en-us&format=rss_200' )

What is the expected output? What do you see instead?

       With view source in browser you can see media:content
       elements on each item.  The media content elements look 
       like 
          <media:content url="http://farm2.static.flickr.com/1275/5178814367_687c0489c2_m.jpg" .... />

       But searching the parsed feed's entry list, no entries can
       be found that have url data matching what's in the source
       feed's media:content elements.

What version of the product are you using? On what operating system?

       Version 4.1 on Linux and Mac

Here's the fix -

   1) Add http://search.yahoo.com/mrss/ to the _FeedParserMixin namespaces
   2) Add a _start_media_content handler to _FeedParserMixin

Here's the patch, and I've attached a test file.

Thanks,

Submitting a slightly better solution -- use FeedParserDict for element 
attributes.

Also implement same fix for media_thumbnail

Never mind -- similar to issue 192, which was fixed well enough in revision 296.

Weird, I'm using feedparser (__version__ is set to '4.1') to parse a Flickr 
feed, and while my entries do get some of the media_* fields, the important 
ones are empty which is a bummer. Here's what I get

from feedparser import parse

f = 
parse("http://api.flickr.com/services/feeds/photos_public.gne?id=37343463@N08&la
ng=en-us&format=rss_200")

e = f.entries[0]

In [79]: sorted(e.keys())
Out[79]: 
['author',
 'author_detail',
 'dc_date.taken',
 'guidislink',
 'id',
 'license',
 'link',
 'links',
 'media_category',
 'media_content',
 'media_credit',
 'media_thumbnail',
 'summary',
 'summary_detail',
 'title',
 'title_detail',
 'updated',
 'updated_parsed']

In [80]: (e.media_category, e.media_content, e.media_credit, e.media_thumbnail)
Out[80]: (u'barcamp unconference barcamplondon bcl8', u'', u'bfirsh', u'')

As you can see both 'media_content' and 'media_thumbnail' are empty, and those 
are *exactly* the fields I need, which renders feedparser completely useless in 
this particular case.

Any ideas on how to fix this?

This is what I get:
>>> from feedparser import parse
>>> 
>>> f = 
parse("http://api.flickr.com/services/feeds/photos_public.gne?id=37343463@N08&la
ng=en-us&format=rss_200")
>>> 
>>> e = f.entries[0]
>>> sorted(e.keys())
['author', 'author_detail', 'dc_date.taken', 'guidislink', 'href', 'id', 
'link', 'links', 'media_content', 'media_credit', 'media_thumbnail', 'summary', 
'summary_detail', 'title', 'title_detail', 'updated', 'updated_parsed']
>>> e.media_content
[{'url': u'http://farm5.static.flickr.com/4151/5196207597_80cef881c4_o.jpg', 
'width': u'5184', 'type': u'image/jpeg', 'height': u'3456'}]
>>> e.media_thumbnail
[{'url': u'http://farm5.static.flickr.com/4151/5196207597_37cb589e1f_s.jpg', 
'width': u'75', 'height': u'75'}]

The problem appears to be that you are using version 4.1 rather than the HEAD 
version from Subversion. If you switch to the latest code you should see that 
this has been fixed. I'm marking this as fixed but please update this thread if 
it still doesn't work using the latest code.
