Created attachment 307297 [details] build.log $summary
Seems it's not dup of bug 393313, the error message is different. But why you are not using 2.17? Do you have same problem with 2.17 or 9999? maksbotan, may be it's time to remove <2.17 versions?

Created attachment 307761 [details, diff] patch to the source code and makefile I have test it on my pc . Can compile correctly!
2.16 fails the same way for me on x86. 2.17 indeed wants a newer ffmpeg then requested (0.10.2). only media-libs/ffmpegsource-2.16.2.1_pre587 works for me! Should we proceed with that one in regard to Bug 401069?
I still suggest removing all 2.16 ebuilds.
2.16 was removed from tree.
