Change:
After installing and running doesn't show the additional plugins. Anyway, one can set to e.g. and the plugins are properly loaded.
Wasn't this fixed yet?
Doesn't work for me on master.
I think it's questionable whether this is desirable. We've had a similar discussion about python packages. In the case of similar plugins there's also the possibility that the version combination might make them incompatible; upstream packages typically assume that the packaging system ensures consistency, so this may result in ugly failures.
It seems like we still need some solution to this; we're shipping stuff that can't work: That's with all the plugin packages and everything installed. Add to the environment, though:
I have same thing here, 17.09. gst-play-1.0 foo Failed to create 'playbin' element. Check your GStreamer installation.

Also setting doesn't help as doesn't even exist. Is there something I'm missing? EDIT: works. Now I'm wondering if there is a way to make this more seamless? EDIT2: Apperently the is already properly set in  to: However for some reason it gets replaced in the final file the get replaces by which causes the expasion to fail. It is probably an issue with . EDIT3: Issue might be caused by this:
