[gentoo-user] ffmpeg and libav

[john]

Hello,

I have changed by use flag for ffmpeg to include theora. When i try
emerge I get the following

[blocks B      ] media-video/ffmpeg ("media-video/ffmpeg" is blocking
media-video/libav-0.8.2)

 * Error: The above package list contains packages which cannot be
 * installed at the same time on the same system.

  (media-video/ffmpeg-0.10.2::gentoo, ebuild scheduled for merge)
  pulled in by media-video/ffmpeg required by @selected

  (media-video/libav-0.8.2::gentoo, ebuild scheduled for merge) pulled
  in by
  >=media-video/libav-0.8.1[X,encode,-jpeg2k,-mp3,-sdl,-theora,-threads,-truetype,-vaapi,-vdpau,-x264]
  required by (virtual/ffmpeg-0.10.2-r1::gentoo, ebuild scheduled for
  merge)


This happens for several use flags (mp3 aac)


Does this mean that ffmpeg no longer supports mp3 x264 theora etc?

And if I need to codecise an mp3 I cannot use ffmpeg?

Or have I lost the plot?
