FFmpeg builds

Prebuilt, self-contained FFmpeg libraries and programs for every major platform: FFmpeg 8.x and 9.x, each in four license variants, with the whisper.cpp speech-to-text filter (whisper) built in. Download them from the releases.

They are built from ffmpeg-build.yml by ffmpeg-build: every library version is locked in ffmpeg.lock, every license is checked before anything builds, and each archive carries its license notices. Using the builds covers each platform.

Platforms

OS	RIDs
Windows	win-x64, win-arm64
Linux (glibc)	linux-x64, linux-arm64, linux-armhf
Linux (musl / Alpine)	linux-musl-x64, linux-musl-arm64
macOS	osx-x64, osx-arm64
Android	android-arm64, android-x64
iOS and Mac Catalyst	ios-arm64, ios-sim-arm64, maccatalyst-arm64 + maccatalyst-x64, in one .xcframework bundle

Every platform ships shared libraries (.dll, .so, .dylib; iOS as dynamic frameworks). The Linux builds are self-contained: nothing to install to run them.

License variants

Each platform is built four times. Pick by family and version:

• Family: gpl adds the x264 and x265 encoders; lgpl uses kvazaar for HEVC and leaves x264/x265 out, so linking it doesn't put your app under the GPL.
• Version: v3 (GPLv3 / LGPLv3) may use the Apache-2.0 libraries: OpenSSL, the Vulkan loader, and MoltenVK on Apple. v2 (GPLv2 / LGPLv2.1) can't. lgplv2 is the App Store variant: v3's anti-tivoization terms don't fit the App Store.

Variant	TLS (Linux, Android, Mac Catalyst)	SRT/RIST encryption	Vulkan filters	Whisper on the GPU (Vulkan)
gplv3	OpenSSL	yes	yes	Linux, Windows, Android
lgplv3	OpenSSL	yes	yes	Linux, Windows, Android
gplv2	GnuTLS	yes	no	Windows, Android
lgplv2	none	no	no	Windows, Android

Windows always uses SChannel and macOS/iOS SecureTransport for TLS. Whisper uses Metal on every Apple build, and the CPU on linux-armhf (and wherever no GPU is found). On v2 Windows and Android builds, Whisper's GPU path uses the system's own Vulkan library, so nothing Apache-2.0 is shipped.

Releases

Releases are tagged <FFmpeg version>.<build>, e.g. 9.0.2.4; the build number goes up whenever anything a release is made of changes (a library version, the build definition, the engine). Each release has, per platform and variant:

• ffmpeg-<version>-<rid>-<variant>.tar.gz: the programs and shared libraries, with THIRD-PARTY-NOTICES.txt (the variant's license, how FFmpeg was built, and every bundled library's license texts).
• ffmpeg-<version>-<rid>-<variant>-dev.tar.gz (desktop platforms): headers, pkg-config files and, on Windows, MSVC import libraries.
• ffmpeg-<version>-ios-<variant>.tar.gz: the iOS and Mac Catalyst .xcframework bundle.

plus SHA256SUMS, manifest.yml (what each build contains) and ffmpeg-<version>-sources.tar.gz (the source of every library in the release).

License

The build definition in this repository is MIT (LICENSE). FFmpeg and the libraries are under the GNU (L)GPL and various permissive licenses; each archive's THIRD-PARTY-NOTICES.txt says which, in full.
