FFmpeg Static Auto-Builds

Static Windows (x86_64) and Linux (x86_64) Builds of ffmpeg master and latest release branch.

Windows builds are targetting Windows 7 and newer.

Linux (x86_64) builds are targetting Ubuntu 16.04 (glibc-2.23 + linux-4.4) and anything more recent.

Linux (arm64) builds are targetting Ubuntu 18.04 (glibc-2.27 + linux-4.15) and anything more recent.

Auto-Builds

Builds run daily at 12:00 UTC (or GitHubs idea of that time) and are automatically released on success.

Auto-Builds run ONLY for win64 and linux(arm)64. There are no win32/x86 auto-builds, though you can produce win32 builds yourself following the instructions below.

Release Retention Policy

• The last build of each month is kept for two years.
• The last 14 daily builds are kept.
• The special "latest" build floats and provides consistent URLs always pointing to the latest build.

Package List

For a list of included dependencies check the scripts.d directory. Every file corresponds to its respective package.

How to make a build

Prerequisites

• bash
• docker

Build Image

• ./makeimage.sh target variant [addin [addin] [addin] ...]

Build FFmpeg

• ./build.sh target variant [addin [addin] [addin] ...]

On success, the resulting zip file will be in the artifacts subdir.

Targets, Variants and Addins

Available targets:

• win64 (x86_64 Windows)
• win32 (x86 Windows)
• linux64 (x86_64 Linux, glibc>=2.23, linux>=4.4)
• linuxarm64 (arm64 (aarch64) Linux, glibc>=2.27, linux>=4.15)

The linuxarm64 target will not build some dependencies due to lack of arm64 (aarch64) architecture support or cross-compiling restrictions.

• davs2 and xavs2: aarch64 support is broken.
• libmfx and libva: Library for Intel QSV, so there is no aarch64 support.

Available variants:

• gpl Includes all dependencies, even those that require full GPL instead of just LGPL.
• lgpl Lacking libraries that are GPL-only. Most prominently libx264 and libx265.
• nonfree Includes fdk-aac in addition to all the dependencies of the gpl variant.
• gpl-shared Same as gpl, but comes with the libav* family of shared libs instead of pure static executables.
• lgpl-shared Same again, but with the lgpl set of dependencies.
• nonfree-shared Same again, but with the nonfree set of dependencies.

All of those can be optionally combined with any combination of addins:

• 4.4 to build from the 4.4 release branch instead of master.
• 5.0 to build from the 5.0 release branch instead of master.
• 5.1 to build from the 5.1 release branch instead of master.
• debug to not strip debug symbols from the binaries. This increases the output size by about 250MB.
• lto build all dependencies and ffmpeg with -flto=auto (HIGHLY EXPERIMENTAL, broken for Windows, sometimes works for Linux)
