chore(libdca): remove DTS Coherent Acoustics decoder from distro#17330
Merged
Conversation
libdca provides DTS Coherent Acoustics audio decoding, a niche
multimedia codec we do not want to maintain.
Reverse-dependency check: the only spec referencing libdca is
gstreamer1-plugins-bad-free, whose 'BuildRequires: pkgconfig(libdca)'
is gated by '%if %{with extras}'. Our existing
base/comps/gstreamer1-plugins-bad-free overlay disables that bcond
(build.without = ["extras", ...]), so removing libdca has no effect
on any currently-built component.
Drops the component definition, lock file, and rendered spec in a
single commit so the tree remains bisectable and self-consistent.

Pull request overview
Removes the libdca (DTS Coherent Acoustics) decoder component from the Azure Linux distro to reduce long-term maintenance burden for a niche codec, relying on the existing gstreamer1-plugins-bad-free configuration that disables the extras bcond (where pkgconfig(libdca) is referenced).
Changes:
- Dropped
libdcafrom the base component list (base/comps/components.toml). - Removed the
libdcalock file (locks/libdca.lock). - Removed the rendered spec artifacts for
libdca(specs/l/libdca/*).
