# 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 [addins]`
### Build FFmpeg
* `./build.sh target variant [addins]`
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:
* `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.
* `debug` to not strip debug symbols from the binaries. This increases the output size by about 250MB.
