V1.60

on GitHub

Highlights

• FFmpeg 9.0 (was 8.1).
• Subtitle rendering: libass is now built and enabled, together with fribidi
  (bidirectional text), harfbuzz (text shaping), libunibreak (Unicode line breaking for
  CJK/Thai) and fontconfig (font lookup by name). SRT/ASS subtitles can be burned into video
  via the subtitles and ass filters, and drawtext now accepts font=Helvetica instead of
  requiring an explicit fontfile= path.
• AviSynth+ support (--enable-avisynth, GPL/non-free builds only). Only the headers are
  built; the AviSynth+ library is loaded at runtime and has to be installed separately.
• libxml2 is built and enabled, which the DASH and IMF demuxers require.
• lcms2 is now actually enabled, giving ICC profile support in the image decoders and the
  iccdetect/iccgen filters.
• CUDA 13.3.1 for the CUDA docker image (was 12.6.2/12.9.0).
• The README now documents what every optional library actually enables.

Fixes

• ffplay was silently not being built. ffmpeg 9.0 requires SDL2 (sdl2 >= 2.0.1, < 3.0.0),
  so the SDL3 build produced no usable sdl2.pc and configure quietly dropped ffplay. The build
  still reported success and the docker images then failed copying a binary that never existed.
  The script is back on SDL2.
• --enable-vaapi was never passed. library_exists() tested pkg-config's (empty) output
  instead of its exit code and always reported the library as missing.
• A failed cd after extraction only exited a subshell, so the script kept building in the
  previous package's directory.
• Unknown --options were silently ignored. The argument parser now has one explicit case
  per option and errors out on anything else; cleanup is deferred until the whole command line
  has been parsed.
• .git is restored from .git.bak via an EXIT trap, so a failed build no longer leaves
  the repository renamed.
• Binaries are portable again: removed -march=native (zix) and -C target-cpu=native
  (rav1e).
• The install step checks each copy, only handles ffplay and manpages when they were actually
  built, and no longer prints a misleading "already built" message for ffmpeg itself.
• --enable-libzmq was only added inside the libzmq build block, so it was dropped on rebuilds.
• Fixed the giflib 6.x install, the fontconfig tools linking against static brotli, GNU mirror
  downloads, and the OpenCL ICD loader building its test suite unnecessarily.
• gperf is now built, since fontconfig needs it on Linux.
• Fontconfig configuration and DejaVu fonts are shipped in the docker images
  (FONTCONFIG_PATH=/etc/fonts); without this, drawtext cannot resolve fonts by name and
  libass falls back to a default font.
• The full-static CI job pulled a CUDA base image it never used — it builds FROM ubuntu:24.04.

Build script / CI

• Every dependency now builds in its own build_<package>() function, dispatched from the
  ordered PACKAGE_BUILD_ORDER array. Behavior is unchanged — verified against stubbed execution
  transcripts in 17 configurations and a full docker build producing an identical ffmpeg
  configure line.
• Shell formatting is pinned with .editorconfig and enforced in CI by a new lint job running
  shfmt and shellcheck --severity=error. The reformatting commits are listed in
  .git-blame-ignore-revs.
• actions/checkout updated to v5 (v4 runs on the deprecated Node.js 20 runtime).
• The cuda-samples checkout is pinned to a tag matching the CUDA version instead of tracking
  master, whose directory layout changed in v13.0.
