FFmpeg-Builds-master是FFmpeg在不同平台下的预编译版本

# 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)
