libav and ffmpeg blocking problem

How do I get past this blocking problem?
I've tried unmerging vlc, mplayer, libav and ffmpeg, but that has not worked. I added -libav and ffmpeg to USE in make.conf, but that did nothing.

Code:

[blocks B      ] media-video/ffmpeg:0 ("media-video/ffmpeg:0" is blocking media-video/libav-9.17)

Total: 99 packages (58 upgrades, 8 new, 5 in new slots, 28 reinstalls, 1 uninstall), Size of downloads: 520,342 KiB

 * Error: The above package list contains packages which cannot be

Hi
Is this still open?
Not too easy to change from ffmpeg to libav, but definitely possible... .
You basically have to force everything - you're getting all the warnings because the other packages that you have installed are currently pointing to the ffmpeg libs (and have therefore to be rebuilt so that they point to the libav libs)

I've worked around the problem. The command I normally use for updating is

Code:

emerge -avDu --keep-going --autounmask-write world

I removed -D and emerged vlc on its own.

At times like this I'm tempted to start from scratch again with current stuff rather than trying to update.

Eh well, swapping ffmpeg to libav has been hard as well for me.
But since I successfully swapped I can run "emerge --update --deep --newuse world" without any problems related to ffmpeg/libav.
One thing that keeps creating issues since years is Perl: I hate Perl on both sides - I hate the language itself and as well its management in Gentoo.
But otherwise I love the install_once-update_forever approach of Gentoo - in my opinion all distributions should adopt it

Would you believe I forgot to use --newuse after changing USE?

I belong in a nice, warm padded cell!
