Mostly repeats commit 917dce846463e4ae33067da3284c606517c3ffbd's
message that added it. Situation is not ideal so it may be
confusing to some.
An alternative to the postinst message would be to mask/unkeyword
the recent/latest nv-codec-headers and only expose the one that
works for all (non-masked/legacy) drivers.
^ as a bit of a middle ground, this changes the ebuild's stabilization
comment to only stabilize versions that work for all driver versions.
So only ~arch users using bleeding headers but old drivers will need to
juggle.
The other (messier) alternative would be to put nv-codec-headers:=
in RDEPEND for revdeps, depend on >=nvidia-${min} here, and do
SLOT="0/${min}":
Pros:
- ensures nvdec/nvenc will work
- no need to think about rebuilds when downgrading
Cons (not *major* issues except maybe the last one):
- confusing to have nv-codec-*headers* in RDEPEND for revdeps
- installs headers for nothing on binhosts (not that these are huge)
- rebuilds are not essential for using latest drivers, and ffmpeg
is not that trivial to rebuild
- prevents binhost from giving optional support without also pulling
the (big) nvidia-drivers even on e.g. amdgpu machines -- fwiw most
binary distros can (should) just enable this for everyone
- portage may give confusing conflicts if users mask latest drivers,
good to ensure nvenc/nvdec keeps working but that's often a low
priority for users trying to debug (other) issues with drivers
that often have nothing to do with nvenc/nvdec, rebuilds when
just testing drivers back&forth would also be *very* annoying
Note that in the past this did depend on >=nvidia-${min} (without
subslot), and revdeps were using USE=video_cards_nvidia to enable
support. This caused a lot of headaches for users of legacy drivers
that lost support without having explicitly opted in.
Eventually USE was renamed, and later someone (imo rightfully)
thought the dependency in a header-only package was weird and
dropped that too.
