Code:

emerge -a ffmpeg


output

Code:

* IMPORTANT: 2 config files in '/etc/portage' need updating.

These are the packages that would be merged, in order:

Calculating dependencies 
 * IMPORTANT: 9 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.

 * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
 * sections of the emerge man page to learn how to update config files.
... done!

!!! The ebuild selected to satisfy "media-libs/libsdl2[sound,video,abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?]" has unmet requirements.
- media-libs/libsdl2-2.24.0-r2::gentoo USE="X alsa dbus jack joystick opengl pipewire sound threads udev video wayland (-aqua) (-custom-cflags) -doc -fcitx4 -gles1 -gles2 -haptic -ibus -kms -libsamplerate -nas -oss -pulseaudio -sndio -static-libs -vulkan -xscreensaver" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="mmx sse sse2 -3dnow" VIDEO_CARDS="(-vc4)"

  The following REQUIRED_USE flag constraints are unsatisfied:
    wayland? ( gles2 )

  The above constraints are a subset of the following complete expression:
    alsa? ( sound ) fcitx4? ( dbus ) gles1? ( video ) gles2? ( video ) haptic? ( joystick ) ibus? ( dbus ) jack? ( sound ) nas? ( sound ) opengl? ( video ) pulseaudio? ( sound ) sndio? ( sound ) vulkan? ( video ) wayland? ( gles2 ) xscreensaver? ( X )

(dependency required by "media-video/ffmpeg-4.4.2::gentoo" [ebuild])
(dependency required by "ffmpeg" [argument])


Come si risolve?

Questo è il mio make.conf
Code:

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
COMMON_FLAGS="-march=native -O2 -pipe"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"

MAKEOPTS="-j16"

# NOTE: This stage was built with the bindist Use flag enabled
PORTDIR="/var/db/repos/gentoo"
DISTDIR="/var/cache/distfiles"
PKGDIR="/var/cache/binpkgs"

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.
LC_MESSAGES=C

USE = "qt5 -kde X gtk -gnome pipewire alsa systemd networkmanager wayland initramfs bluetooth dbus gstreamer jack"

Code:
  The following REQUIRED_USE flag constraints are unsatisfied:
    wayland? ( gles2 )

Il messaggio dice che se hai la use flag wayland settata (wayland?) allora devi anche abilitare la use flag gles2.
Per fare questo puoi usare /etc/portage/package.use.
