Guardian plugin doesn't work

[Amr Ibrahim]

There are two bugs here:
1. packagekit was using app-install-data to search for missing codecs
2. The Guardian Videos channel does not work

(1) is supposedly fixed in all cases.

To reproduce:

1. Open Totem
2. Go to Channels and select The Guardian Videos
3. Select any video
4. Totem complains about missing codecs
5. GNOME Software then complains that app-install-data is missing

See screenshots.

It's possible this is a totem or gst bug. What I currently see -
1. The app-install-data warning is longstanding, bug here
  https://bugs.launchpad.net/ubuntu/+source/packagekit/+bug/1716137
2. At least here 'easy-codec-install' works fine on supported local files
3. A text/html decoder missing usually refers to unsupported or unknown type
4. If one was to install gst libav, bad & ugly plugins the Guardian vids still won't work, same error about text/html

Noting this isn't a fresh install from latest image I'm checking on..

[Matthias Klumpp (ximion)]

Indeed, I can reproduce this. This issue affects Debian as well, and I wonder why nobody noticed it so far.
I have an idea on how to fix it.

[Doug McMahon (mc3man)]

Just tried latest image updated.
See no issue with local files that gst supports
As far as channels the guardian one is broken, apple trailers is ok

Ex.
guardian -
$ totem

As far as guardian videos this bug doesn't seem to have ever been fixed, if that's true it should be removed from grilo or grilo-plugins
https://bugzilla.gnome.org/show_bug.cgi?id=771215

[Matthias Klumpp (ximion)]

I fixed the bug mentioned in this report (the error message should be gone now and you should be able to search for mimetypes with PackageKit again).
However, it could be possible that the error described here was masking another issue with missing codecs itself (I can't test that at time).

In any case, you can test this by upgrading PackageKit to version 1.1.7-1 (currently in Debian, maybe synced to Ubuntu), or by applying https://github.com/hughsie/PackageKit/commit/5e8a20440ca53080d5409a10f211a0979545816f

[Doug McMahon (mc3man)]

I'm not sure if this is a dupe, this bug should be only about the non working grilo plugin for guardian videos. Can't see how fixing the erroneous error message is going to change that.

[Doug McMahon (mc3man)]

Using as example the 1st vid shown in that channel -
quvi dump https://www.theguardian.com/football/video/2016/sep/26/is-leicester-ready-for-the-champions-league-video
error: libquvi: while parsing media properties: /usr/share/libquvi-scripts/0.9/media/guardian.lua:91: attempt to perform arithmetic on a nil value

If you used mpv the vid would play (thanks to youtube-dl
