Trying to do an emerge world:

Code:
# emerge -av --update --newuse --deep --with-bdeps=y  --keep-going @world


And I get the following:

Code:

Add vaapi USE flag to media-video/ffmpeg and try again.

You need to decide if you want libav or ffmpeg.

If you want ffmpeg, add -libav to your USE in make.conf, i.e.:

Code:
USE="... -libav"


If you want libav, then deselect ffmpeg which is in your world file for some reason:

Code:
emerge --deselect media-video/ffmpeg


Then try again.

Can you elaborate on this? Going forward is it no longer possible to have both on one system? Is there a way to take advantage of vaapi offloading with ffmpeg and not libva?

It's never been possible to have both on one system. The system was simply changed to ask for an informed decision instead of picking a default based on politics. vaapi and vdpau both work in ffmpeg, if you bother to set the use flags correctly.

That doesn't appear to be true; I have both and I don't have anything unmasked or forced/nodeps:
<<<<<
$ eix-installed all | egrep 'libva|ffmpeg'
media-video/ffmpeg-2.2.12
media-video/ffmpegthumbnailer-2.0.8
virtual/ffmpeg-9-r2
x11-libs/libva-1.5.0
x11-libs/libva-intel-driver-1.5.0
x11-libs/libva-vdpau-driver-0.7.4-r2
>>>>>

When I updated yesterday, which was the first time in about a week, it was the first time I ran into conflicts with having them both.

Basically, I just want to ensure I'm able to use VA-API with mpv, Handbrake, & XBMC. If that all works fine with FFmpeg by just adding the vaapi USE flag, then I'm good, but I wasn't clear on that. I also use VDPAU and know that it works with ffmpeg, but it's a pain with primus/optimus (I have a hybrid card, and sticking with Intel/VA-API is much easier to maintain).

Just a small note, it's not libva, it should be libav. Those 2 are completely different packages

Well, I don't have libav installed. I did add -libav to the USE flag, but no dice. :(

I alos got this:

Code:
(media-video/libav-11.2:0/10::gentoo, ebuild scheduled for merge) pulled in by
    >=media-video/libav-9.12[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?,X?,encode?,gsm?,jpeg2k?,mp3?,opus?,sdl?,speex?,theora?,threads?,truetype?,vaapi?,vdpau?,x264?] (>=media-video/libav-9.12[abi_x86_64(-),X,encode,mp3,truetype,x264]) required by (virtual/ffmpeg-9-r2:0/0::gentoo, ebuild scheduled for merge)


Suggesting that ffmpeg requires libav?

  media-video/libav-11.2 pulled in by:
    virtual/ffmpeg-9-r2 requires >=media-video/libav-9.12[abi_x86_64(-),X,encode,mp3,truetype,x264]


So it seems that ffmpeg requires libav?

Ok, you are doing 2 counterdicting things. When you put -libav, it means you do NOT want libav.
That flag also tells virtual/ffmpeg to NOT use libav, while your command of emerge -avc libav is asking to install libav even though you do NOT want it (set by the -libav Use flag).

Virtual/ffmpeg and media-video/ffmpeg are 2 differents. Virtual/ffmpeg is only there to make sure you can only install EITHER libav or ffmpeg set by the libav USE flag.

As mgorny just said, setting -libav meas you want ffmpeg, setting libav means you want libav.

Also, it should be a capital C, not lower case for uninstall. (linux is case sensitive, uppercase means something different than lower case)
The safer method of removing a package is, using --depclean instead of -C

I realize that. I was using -c (of --deplcean) to show dependency. I did not install libav. (that why the -a was in). Sorry if I wasn't clear. libav was not installed on my system.

I did not try to uninstall libav, since libav was not installed.

I need to put -libav in package.use for ffmpeg. Not sure why adding -libav in make.conf didn't do the trick.

It should, so check for typos!

I have a similar issue: I can see some “ffmpeg -libav” in the packages useflags so I think that I have the appropriated USE but I can’t upgrade my system and I can’t explicitly install ffmpeg.

Code:
pikachu ~ # emerge -va --update --newuse --deep --with-bdeps\=y @world

You currently have libav and libpostproc installed. If you want to keep using that, you need to add USE=libav to your make.conf. If you want to switch to media-video/ffmpeg, then you need to unmerge libav and libpostproc.

I can’t unmerge this package although I have the useflags -libav and ffmpeg.
Code:
pikachu ~ # emerge -va --depclean media-libs/libpostproc
!!! SYNC setting found in make.conf.
    This setting is Deprecated and no longer used.  Please ensure your 'sync-type' and 'sync-uri' are set correctly in /etc/portage/repos.conf/gentoo.conf
