Hi Eugen,

Thanks for your offer, but I won't have too much free time today for
testing, sorry. I could be more available tomorrow morning, I'll let
you know.

I found something quite interesting: even though the Raspberry Pi 2
supports the NEON set of instructions, I couldn't get libav-0.8.17 to
compile with NEON enabled.

I just checked with libav-11.4, and the configure script seems to like
NEON better :) Using these instructions could lead to a significant
performance boost on ARM platform, and maybe make Ekiga usable on the
Raspberry Pi 2. I'll give this a try ASAP !

Ultimately, If that doesn't work, we'll have to use a beefier, x86
based machine (which is already ordered).

Cheers, Samuel
