I even tried with USE=mplayer but it still pulls ffmpeg. So I can not do an emerge -uD world How do I resolve this?
IIRC k9copy hard-requires ffmpeg, thus there is no solution.
Ok is there a proper way to keep ffmpeg instead of libav? I tried masking stuff but that didn't seem to work.
You could try turning off the libav USE flag and running emerge --changed-use world
