Operators no longer have to install ffmpeg manually. Both the release
tarballs (5 platforms × 2 binaries) and the Docker image now ship a
working ffmpeg + ffprobe pair adjacent to the unarr binary;
ResolveFFmpeg / ResolveFFprobe pick them up via the "adjacent to
executable" branch with zero configuration.
Tarball bundle (scripts/download-ffmpeg-static.sh + .goreleaser.yml):
- ffbinaries.com (johnvansickle / Zeranoe-style static GPL builds) for
linux-amd64, linux-arm64, darwin-amd64, windows-amd64
- evermeet.cx universal Mach-O for darwin-arm64 (ffbinaries lacks it)
- BtbN/FFmpeg-Builds for windows-arm64 (ffbinaries lacks it)
- Idempotent fetch with curl --retry 5 so transient github.com SSL
errors don't fail the goreleaser before-hook
- New `before.hooks` runs the script automatically per release; archive
files glob `dist-ffbinaries/{{ .Os }}-{{ .Arch }}/*` + strip_parent
- Migrated to non-deprecated `formats: [tar.gz]` / `formats: [zip]`
- Verified via `goreleaser release --snapshot --clean --skip=publish` —
6 archives all carry ffmpeg + ffprobe (~60-130MB each)
Docker image (Dockerfile):
- Replaced the failing BtbN static glibc binaries with Alpine's native
musl `apk add ffmpeg`. The static GPL builds need glibc + libmvec /
libgcc_s; gcompat alone is not enough (vector-math symbols unresolved).
Alpine ships ffmpeg 6.1.2 which is fine for the WebRTC transcoder.
- Image size 174MB, built + ffmpeg/ffprobe/unarr smoke OK.
Targets the v0.8 unarr release (per user direction — new feature, not
a patch). dist-ffbinaries/ added to .gitignore.
