... while no package seems to need it!
Hi.
I'm facing a curious issue with portage: as I'm emerging -avquDN --changed-use --keep-going=y world it wants to pull down >=ffmpeg-2.8 (masked) although I found no clue any package requires it. Currently version 2.6 (stable) is installed. Portage pretended version 2.8 was required by mpd:
| Code: | The following keyword changes are necessary to proceed:
(see "package.accept_keywords" in the portage(5) man page for more details)
# required by media-sound/mpd-0.19.10::gentoo[-libav,ffmpeg]
# required by @selected
# required by @world (argument)
=media-video/ffmpeg-2.8.3 ~amd64 |
So I upgraded mpd yet portage sticks on ffmpeg-2.8.3. Just this time it lies because not mpd requires it. I then demanded the dependency tree (emerge -tav...) and saw ffmpeg-2.8 was also pulled by gst-plugins-libav-1.4.5-r2... which I upgraded independently: no masked ffmpeg was pulled! I then tried once again to emerge ... world and once again >=ffmpeg-2.8 was requested.
I repeated this process and found kodi-15.2 (I have version 15.1) also allegedly relied upon ffmpeg-2.8. Did upgrade kodi then retried upgrading world, same, nonsensical request upon ffmpeg-2.8 pulled by mpd – WTF?
In an attempt to nail down the "culprit", I tried the following:
| emerge -pu1 $(equery -q d ffmpeg | sed -r 's/-[0-9.]+.*$//g'): | These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild rR ] net-fs/libnfs-1.9.7 [1.9.7]
[ebuild U ~] media-libs/babl-0.1.14 [0.1.12]
[ebuild U ~] media-video/ffmpeg-2.8.3 [2.6.3] USE="-libressl% -snappy%" FFTOOLS="sidxindex%*"
[ebuild NS ~] media-libs/gegl-0.3.4 [0.2.0-r2] USE="cairo ffmpeg jpeg lcms lensfun openexr png sdl svg tiff v4l -debug -introspection -jpeg2k -raw {-test} -umfpack -vala -webp" CPU_FLAGS_X86="mmx sse"
[ebuild U ] media-video/vlc-2.2.1-r1 [2.1.5-r1] USE="jpeg%* libsamplerate* zeroconf%* -postproc* -qt5% -vpx% -x265%"
[ebuild U ] net-misc/freerdp-1.2.1_pre20150326-r1 [1.2.1_pre20150326] USE="(-libressl)"
[ebuild U ] media-sound/audacious-3.6.2 [3.4.1] USE="-gtk3% -qt5%"
[ebuild U ] media-plugins/audacious-plugins-3.6.2-r1 [3.4.1] USE="-gtk3% -http% -qt5%"
[ebuild U ~] media-tv/kodi-15.2 [15.1]
The following keyword changes are necessary to proceed:
(see "package.accept_keywords" in the portage(5) man page for more details)
# required by media-libs/gegl-0.2.0-r2::gentoo
# required by media-libs/gegl (argument)
=media-video/ffmpeg-2.8.3 ~amd64 |
... aaaaand *bingo* ! There we are: media-libs/gegl-0.2.0-r2 is the one requiring ffmpeg-2.8!
The question is «why the Hell didn't portage figure it out while emerging world?»
Bug?

| Sorry for replying to such an old thread, but I'm curious how you solved this. I suspect you needed to add "-ffmpeg" to USE in make.conf. |

Astronome ... no, because media-video/ffmpeg is satisfying virtual/ffmpeg and one or other of [-libav,ffmpeg] or [libav,-ffmpeg] is required. I suspect the above was a teathing issue related to 2015-04-16-ffmpeg-default.

Well, first off, I didn't solve this issue, I got rid of the package that exhibited the issue. In fact it's not about masking any of ffmpeg or libav rather than some portage "deficiency" at tracing dependencies properly or showing them properly... or whatever it is.
The problem is *I* have been required to track down what package was pulling down an unwanted version of ffmpeg while portage should have done that on itself and properly shown which package it depended on. It forced me to do the digging all on my own. And I still have got no explanation on this. Both suck.
