Thanks for the advice. Have removed media-video/ffmpeg and emerge |
43 |
virtual/ffmpeg which is allowing me to emerge virtual/ffmpeg and libav. |

|
45 |
I suppose if I wanted to use media-video/ffmpeg and I could mask libav. |

Thanks for your help. I see this is allowing you to choose |
48 |
between libav and ffmpeg. The value of virtual packages. |
