$summary [snip] configure: error: Requested 'libavformat >= 54.29.104' but version of libavformat is 54.20.4
The deps may need tweaking. Can you try it with latest stable ffmpeg?
Latest stable is media-libs/libav-9.14, which I have been using.
...but builds successfully with libav-9.17 :)
Sorry, last message is wrong (me being on the wrong system). :| So, it also fails to build with libav-9.17. Success with libav-10.5 instead.
I get the same error.
Marked it as needing libav-10 or ffmpeg 2.4 + 12 Dec 2014; Ian Whyman <thev00d00@gentoo.org> + mediatomb-0.12.2_pre20140810.ebuild: + Bump libav/ffmpeg deps +
