 Posted: Sun Mar 01, 2015 5:10 pm Post subject: libav / ffmpeg blocking problem when updating [solved] |
 |
|
Hi all,
I am running across some blocked packages when trying to update the system. The problem seems to revolve around my having ffmpeg installed and some packages (xine, mplayer) trying to pull in libav. From what I can tell, and this may be more of a guess, this is partly due to the absence of something like virtual/libav. Any ideas on how to get around this problem?

# emerge -uDNp @world
These are the packages that would be merged, in order:

I simply put "-libav" in /etc/portage/make.conf. Not that I have anything against libav. I understand that there has been a contentious fork, and quite frequently the ones doing the fork are at least interested in better serviceability. But back when I built my systems, ffmpeg was the only game in town, and until either the dust settles or ffmpeg annoyes me, I'm probably going to stick with it.

Thanks, that did the trick. I'm like-minded in terms of libav/ffmpeg. I've been using ffmpeg and it's not broken, so I don't see much reason to change over.
Best,

Well, what I actually did was also putting '-libav' in make.conf  Just wanted to be specific to the error message in my comment. |

From "eselect news":

Title ffmpeg/libav conflict management: USE=libav
Author Michał Górny <mgorny@gentoo.org>
Posted 2015-02-01
Revision 1
The support for automatic choice between ffmpeg and libav is going to be
deprecated in favor of explicit choice via USE flags. This change aims
to solve multiple repeating issues, including Portage undesirably
wanting to replace one package with the other, lack of proper reverse
dependency on ffmpeg/libav upgrades and some of the hard-to-understand
upgrade failures involving blockers. It also may be used to make ffmpeg
and libav co-installable in the future.
The current USE=ffmpeg will maintain its role of enabling optional
support for ffmpeg or a compatible implementation (libav) in a package.
However, whenever appropriate additional USE=libav will be introduced to
control the preference of one implementation over the other.
Users who currently use libav (the Gentoo default) do not have to
perform any action since USE=libav is enabled by default. It should be
noted that the users still need to enable USE=ffmpeg on packages with
optional libav support as well. Users who want to use ffmpeg instead
need to specify USE=-libav in make.conf explicitly.
Please also note that some packages support only one of the two
implementations. An attempt to install one of those packages may result
in blockers requiring the user changes the global USE=libav state.
The most notable example of such package is media-video/mplayer.
media-video/mpv may be used as a replacement for users who prefer libav.
Please do not alter the state of 'libav' flag on a per-package basis
(e.g. via package.use). The flag needs to be set globally to have
consistent value throughout all packages. Otherwise, blockers will
prevent upgrades. |
@dmpogo
setting USE=-libav in /etc/portage/make.conf is the way to go in this case. |

If you haven't seen it, there is also a topic discussing how this move was handled: https://forums.gentoo.org/viewtopic-t-1010096.html.
