Audio Call fails due to linking both gstreamer 0.10 and 1.0

[David Henningsson]

While calling Arun, a gstreamer/pulseaudio hacker, the call fails with an error message. /usr/lib/empathy/empathy-call shows the errors below. According to Arun, this is due to empathy linking against gstreamer 0.10, but also against some other library, which in turn links against gstreamer 1.0.

Yeah, empathy can't move to 1.0 just yet because that would require taking new versions of the farstream stack, which has knock-on effects (a telepathy-farstream transition) that break some other (mainly KDE) packages.

We should wait some time to get Kubuntu a chance to port their stuff.

In the meantime if you don't need to use any of that stuff then you can give empathy from ppa:ubuntu-desktop/gstreamer1.0 a try.

[Iain Lane (laney)]

I believe this is fixed. I split telepathy-farstream into a compatibility package that Kubuntu can keep using for now and updated the main one, then uploaded empathy to enable GStreamer 1.0.

Let me know if you still have problems.
