FFmpeg Builds

Prebuilt, self-contained FFmpeg libraries and binaries for every major platform, in four license variants — multiple major lines (currently 8.x and 9.x) built in parallel, each with the whisper.cpp speech-to-text filter (af_whisper) built in. No network, no external services; every artifact ships the governing license text and each bundled dependency's license under legal/.

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	ios-arm64 (device) + ios-sim-arm64 (simulator), shipped as one .xcframework
Mac Catalyst	maccatalyst-arm64 + maccatalyst-x64, fused into one universal slice of that same .xcframework

Every platform ships dynamic libraries (.dll / .so / .dylib; iOS as a dynamic-framework .xcframework). The glibc Linux builds are self-contained (old-glibc floor, hwaccel libs static-linked) so they run on a bare system with no package install; linux-x64 and linux-arm64 additionally bundle a Vulkan loader, while linux-armhf does not (it has no Vulkan Whisper backend and reaches any system loader through FFmpeg's dlopen path).

License variants

Each platform is built in four cells — pick by family and version:

• Family — gpl adds the x264 + x265 encoders; lgpl uses kvazaar for HEVC and omits x264/x265, so linking it doesn't force your app to the GPL. The one exception is the lean ios-sim-arm64 slice, which carries none of the three software H.26x encoders in any cell.
• Version — v3 is (L)GPLv3 and may link the Apache-2.0 dependencies (OpenSSL TLS + Vulkan); v2 is GPLv2 / LGPLv2.1 with no Vulkan. lgplv2 is the App-Store-safe cell — v3's anti-tivoization terms are incompatible with the Apple App Store, so LGPLv2.1 is the variant you ship to iOS.

Artifact naming: ffmpeg-{version}-{rid}-{gplv3|gplv2|lgplv3|lgplv2}.tar.gz, except the four Apple mobile RIDs (ios-arm64, ios-sim-arm64, maccatalyst-arm64, maccatalyst-x64), which are merged into one ffmpeg-{version}-ios-{cell}.tar.gz asset. The two Catalyst RIDs are lipo-fused into one universal slice, so each xcframework there carries three slices: device, simulator, and Catalyst.

The TLS backend depends on the cell: OpenSSL on v3 (Linux/Android/Mac Catalyst), GnuTLS on gplv2, and no TLS at all on lgplv2 (Linux/Android/Mac Catalyst — no LGPLv2.1-compatible backend exists); Windows uses SChannel and macOS/iOS use SecureTransport in every cell. Mac Catalyst is the exception among Apple targets — SecureTransport is unavailable there, so it follows the Linux/Android ladder. See the docs for the full breakdown.

Documentation

• Install & usage — download, link, and consume per platform, plus the Whisper filter and the development (headers / import-lib) packages.
• Build coverage matrix — every library FFmpeg supports × every platform × license, ✓ where this repo builds it.
• Development — how the builds are produced: the build scripts, CI, and how to add a platform or dependency.
• Security — the security model and how to report an issue.

License

FFmpeg and its dependencies are licensed under the GNU (L)GPL and various permissive licenses. Each release artifact carries its effective-license notice and the full text of every bundled component under legal/ — see the install docs for what to ship.
