This is probably due to unsattisfied useflags on ffmpeg. Try to making both virtual/ffmpeg and media-video/ffmpeg have same useflag (for the subset provided by the virtual/ffmpeg). libav is just other implementation and is specified first so it prints out that one when useflags are not sattisfied.
Thanks Tomáš, setting the virtual/ffmpeg to those of media-video/ffmpeg the issue disappeared.
As per last comment
*** Bug 361613 has been marked as a duplicate of this bug. ***
Isn't this bug / missing feature of the ebuild or possibly portage? I mean, is it really normal that everyone must sync the flags of both ffmpegs by hand? (Portage already does solve correctly situation when ebuild change name ...)
