%description
FFmpeg -- built as a real, moderately-featured library-only stack
(no command-line programs/doc) specifically as a prerequisite for
KPipeWire, which hard-requires libavcodec/libavutil/libavformat/
libavfilter/libswscale via unconditional REQUIRED pkg_check_modules()
calls with no graceful degradation path. FFmpeg itself is confirmed
entirely absent from Azure Linux's package repos (unlike GStreamer,
which turned out to be available for Kamoso earlier this phase --
this is a genuine, verified gap, not an unchecked assumption).
Enabled libvpx (VP8/VP9, real encode+decode, no patent/licensing
issues, confirmed available) instead of chasing libx264 (GPL,
confirmed NOT packaged here) for H.264 -- VP8/VP9 is a fully
functional choice for PipeWire-based Wayland screen-recording
pipelines. zlib/bzlib auto-detected and enabled since their -devel
packages are present. No X11/SDL/ALSA/PulseAudio program-level
integration needed since --disable-programs skips building the
ffmpeg/ffplay/ffprobe binaries entirely -- only the shared libraries
KPipeWire links against are built.

%changelog
* Sun Aug 30 2026 Smech <smechlabs@proton.me> - 7.1-4
- R3 fixed debugsource packaging cleanly; final gap was
  %{_datadir}/ffmpeg/examples/ (source .c files + Makefile + README
  from FFmpeg's own unconditional make install-examples target --
  there's no ./configure flag to skip it). Claimed as %%doc.

* Sun Aug 30 2026 Smech <smechlabs@proton.me> - 7.1-3
- R2's -fno-lto fix worked -- the real compile+link succeeded
  cleanly this time. Only remaining failure was RPM-level: "Empty
  %%files file debugsourcefiles.list", a standard find-debuginfo.sh
  quirk that shows up when a build's debug source-file references
  don't line up with rpmbuild's automatic debuginfo/debugsource
  subpackage generation (plausibly related to the -fno-lto override
  changing how source paths get embedded). Disabled debugsource
  subpackage generation via %%undefine _debugsource_packages, the
  standard fix for this exact error class.

* Sun Aug 30 2026 Smech <smechlabs@proton.me> - 7.1-2
- R1 failed at final link: "relocation R_X86_64_PC32 against
  undefined symbol `mask24l' can not be used when making a shared
  object; recompile with -fPIC" while linking libswscale.so, coming
  from an LTO partition temp file (ltrans*.ltrans.o) -- a real
  interaction bug between this distro's baked-in hardened-gcc LTO
  specs and libswscale's hand-written nasm RGB24 conversion routines
  (rgb_2_rgb.asm), which aren't LTO bitcode and don't mix cleanly
  with LTO-optimized C objects at final link under redhat-hardened-ld.
  Disabled LTO narrowly via --extra-cflags/--extra-ldflags="-fno-lto"
  rather than the much broader --disable-x86asm (which would kill
  nasm-optimized routines across every FFmpeg library, not just this
  one legacy code path).

* Sun Aug 30 2026 Smech <smechlabs@proton.me> - 7.1-1
- Real upstream source. Built specifically as a KPipeWire prerequisite
  after confirming FFmpeg is genuinely absent from this distro's
  repos (per explicit user instruction to pursue this rather than
  skip Spectacle). Library-only build (--disable-programs/--disable-doc)
  with libvpx (real VP8/VP9 codec) instead of the unavailable libx264.
  %%files is a first-pass estimate of standard FFmpeg library/header
  naming, not yet verified against a real build log -- FFmpeg's own
  build system doesn't use CMake/ECM like everything else this
  session, so this is the first classic autoconf-style ./configure
  package built in this repo; expect a real-error correction round.
