[RELEASE] PodCatching Addon
#1
Thumbs Up 
Since yesterday a Addon for Podcast is online. Instead of the "built-in" way of XBMC, this addon take care of "Readed" and "Unreaded" items and is feedet by an opml file.

you find the plugin in the official repository under "audio"

Hey there - not sure if you've gotten any responses on this. I've downloaded and installed this add-on but I'm having a hard time figuring out why it doesnt like the OPML file that I gave it.

According to your README, the script is looking for the the OPML file in /userdata/addon_data/plugin.audio.PodCatcher (not sure if there's a specific name that the script is looking for). I dropped mine in there (podcasts.opml), but I'm getting an error "Unable to read the OPML-File".

Here's my OPML file - maybe there's specific tags that your script isnt finding in mine? If so, maybe you could share a "template" opml that people could paste their rss urls into.


thanks
jm

yeah, i fixed this problem. i didn't mentioned that some attributes are "optional".


but i didn't push this in the repository cause i'am hunting a additional problem.

for quick fix, replace your local __init__.py whit this https://github.com/raptor2101/PodCatcher..._init__.py

Thanks, I updated my install with this file, it gets further but still crashes when using the OPML file from http://www.npr.org/podcasts.opml

Seems that the xmlUrl is not well-formed,

Code:
<outline
                                text=""
                                title=""
                                type="rss"
                                version="RSS"
                                imageHref=""
                                description="Fifty of the most memorable stories from NPR in 2007, as selected by NPR.org's editorial team."
                                typicalDurationMins=""
                                orgId="1"
                                topicId="1008"
                                orgName="National Public Radio"
                                topicName="Arts &amp;amp; Life"
                                xmlUrl="http://www.npr.org/holidays"
                                htmlUrl=""
                        />

So the plugin should probably be made more robust by skipping individuals feeds that don't parse, rather than aborting completely, since most OPML files will often be long and have multiple feeds, which may or may not always parse.

OK, even when I comment-out those broken feeds, still get this error:

you suffer two different erros, with the same source. My parsing algorithm isn't very robust, cause of missing testers... *G*

I will fixe this as soon as possible. As a workaround remove your comments (i guessing you comment out that outline-element)

by the way xmlUrl should link to the RSS/Atom feed. in you case to http://www.npr.org/rss/rss.php?id=1008 instead of http://www.npr.org/series/holidays/.

the last link delivers normal XHTML (wich is seems to be not well formed).

greetings Raptor 2101

sorry for you overhead

OK, trying a more minimal example, I trimmed my OPML file to the following:

i take a closer look at the RSS-Feed. This seems to be a "simple" reding feed not a "podcast". No link to an mediafile is offered.

Code:
<item>
      <title>Wikileaks, the Law and the Press (On The Media: Friday, 10 December 2010)</title>
      <description>In the days since "Cablegate" became international news, there have been a number of suggested strategies to legally punish WikiLeaks and/or Julian Assange. But each would criminalize not only WikiLeaks but news organizations, like &lt;em&gt;The New York Times&lt;/em&gt;, that published those leaks. University of Chicago law professor Geoffrey Stone talks about how the long arm of the law might punish the leaker and the press too.&lt;div class="feedflare"&gt;

i quick fix you problems. now a "broken" link down cause a full crash of the plugin. But now error-detection is hard. I will seek to find a proper way to inform the user how to fix occurring errors...

for you special problem with npr i added a workaround. the addon trys to get the medialink from the feed. If that fails it seeks for a link-item load the page and seek for link with an media ending...

it's a hot fix, so i don't put it to the upstream now, if you want to test it here is the download: http://xbmc.raptor2101.de/plugin.audio.p...0.0.91.zip

Thanks, that seems to work, at least I can now download and play segments from On the Media from NPR. Where does it save the downloaded files, by the way? Does it download-on-the-fly as you play it, or does it download all podcasts at the time you enter? If so, that could be a lot of data for the default NPR OPML which has 100s of feeds.

Also, "Album info" doesn't seem to work (i.e. display information on that podcast), it just restarts the individual podcast.

Also it would be nice:
  • onscreen information in fullscreen mode would use the title information from the podcast, e.g. "December 17 podcast" for the title and "On the Media NPR/WNYC" for the album. Also the date of the podcast could be used (some skins display that in fullscreen mode).
  • display the logo for the individual podcast feed in the thumbnail

But it's great that it's working and thanks for making the plugin! It was a feature that XBMC was definitely lacking. Now all I need is the MythTV PVR addon (which is in the works).

Couldn't you just add an Exception clause to "skip" any feed that doesn't parse, and go to the next one as a workaround? That would enable at least the loading of feeds that did work, even if it didn't warn the user about the ones that didn't load. It's better than the whole plugin crashing.
