Re: [Ekiga-list] Ekiga 4.0.1 and Renavisio

[Eugen Dedu <eugen dedu univ-fcomte fr>]

Hi Samuel,

I propose you to compile opal 3.10.10 with libav version 8, or with 
version 9 and the patch libav9 from 
https://sources.debian.net/src/opal/3.10.10~dfsg2-1/debian/patches/, or 
version 10 with patches libav9 and libav10.

(For your information, the unstable code should work without patches 
with ffmpeg, but not with libav.  Hehe, there are several if-s here, but 
hopefully in the near future everything will be settled.  Debian has 
just switched from libav to ffmpeg.)
