Plugin for GStreamer

[TheAssassin]

We need a plugin that bundles GStreamer related files and updates the AppDir so these files will be loaded by the bundled GStreamer libraries.

The big question is whether GStreamer supports relocation at all.

CC #12.

Seems like bundling the plugins (as a start, all the ones installed should be installed) and then setting an env var is enough. See ubuntu/snapcraft-desktop-helpers#49 and https://developer.gnome.org/gstreamer/stable/gst-running.html.

Therefore: blocked by #81.

Now that the feature is there in linuxdeploy, we could make such a plugin. Volunteers welcome, though; this needs some testing. Writing plugins for linuxdeploy is quite easy, as even shell scripts can be used. @probonopd wanna give it a try?

To be honest I would not even know where to begin.

I guess bundling all GStreamer plugins and then setting the two or three environment variables required to make GStreamer find them should do. Perhaps we'll find some user who needs GStreamer support and implements that then. I don't have a GStreamer app on hand that I could test this with, let's rather do it once there's someone who needs that.
