this is the error I get on a newly installed mg 0.5.0
OS: debian 7.0.

[Boris Bobrov]

This should be fixed in gst10 branch of ​https://gitorious.org/mediagoblin/bretons-mediagoblin/ because playbin was removed

[ayleph]

This is a fairly common message, and it doesn't necessarily indicate a problem. Sometimes the playbin requires a couple of attempts to get playback data. The important part is that a thumbnail was created, which is the desired outcome.

I don't think this is an actual issue; it's just debug messages doing what they're supposed to do. I propose to mark this issue closed/invalid.

[Boris Bobrov]

This does indicate a problem, though it was solved in my branch. This ticket needs to be closed after Chris and I review my code and merge it.

I'll assign the bug on me for now and change its status.

[starwar46]

Facing the exact issues, in my case I experienced:

1. Screenshot/thumbnail captured successfully and it gets displayed on the album page properly.
2. Playback of the video results in audio only, no video.

I am hoping that this is confirmed as a bug and will be fixed soon, any updates?

[Boris Bobrov]

new_gst10 branch in bretons-mediagoblin on gitorious.

breton:

I'm testing this merged with git master... audio works great! Unfortunately I'm hitting a problem with video:

This has happened with all files I've tried updating. I'm using Debian testing over here.

Here's an example file I'm having problems with: ​http://dustycloud.org/tmp/creature_teaser.ogg

[Boris Bobrov]

Could you please post your output of "dpkg-query -s python-gst-1.0"?

[Christopher Allan Webber]

So yeah, python-gst-1.0 wasn't specified by the docs, but now it is! And everything seems to be working well... now merged!

Whooooooo! Thanks for your long work on this, breton!

[ayleph]

Something doesn't seem to work right in the merge. When I run dbupdate, I get:

  File "/srv/mediagoblin/mediagoblin-dev/mediagoblin/media_types/tools.py", line 20, in <module>
    import gi
ImportError: No module named gi

So I installed gi-1.2 via pip. Now when I run dbupdate, I get:

  File "/srv/mediagoblin/mediagoblin-dev/mediagoblin/media_types/tools.py", line 21, in <module>
    gi.require_version('Gst', '1.0')
AttributeError: 'module' object has no attribute 'require_version'

I'm running in a python2.7 environment.

[ayleph]

I found a workaround to my problem. It's not really intuitive though.

I already had the following Arch Linux repository packages installed on my machine:

pygobject2-devel
python2-gobject2

I used pip to remove gi-1.2 from my virtualenv. I used my package manager to install gobject-introspection which didn't solve the issue. Then I used my package manager to install python2-gobject which also pulled in pygobject-devel (py3 version).

It seems that I already had "Python 2 bindings for GObject2" but I was missing "Python 2 bindings for GObject." I don't really get it, but it seems to have worked.

I had warnings about being unable to load plugins for libgstkate.so and libgstopencv.so, but I think I'm okay with that.

[sazius]

Just a note that it seems to be hard to get the right version on Debian wheezy (current stable). There is no python-gst-1.0 in the repos and gi-1.2 via pip doesn't work either as ayleph said.

[Boris Bobrov]

gi is not the package you want. I don't know what's the name of the package on pypi and suggest using packages listed on ​http://mediagoblin.readthedocs.org/en/latest/siteadmin/media-types.html#video

python-gst-1.0 is in debian testing, which is now in freeze. Supporting both gst-0.10 and gst-1.0 branches was not easy and we decided not to include gst-0.10. Maybe it will be in 0.8.1 (though I cannot promise)
