What are the differences between win64 static and shared builds?
Static builds of FFmpeg for Windows 64-bit include all the required libraries and dependencies compiled directly into the executable, making the file size larger but standalone and self-contained.
Shared builds of FFmpeg for Windows 64-bit rely on separate DLL files for the libraries and dependencies, resulting in a smaller executable size but requiring those DLL files to be present on the target system.
Static FFmpeg builds can be more reliable and portable as they don't require external DLLs, but they also tend to have larger file sizes compared to shared builds.
Shared FFmpeg builds allow for smaller executable sizes and potentially better memory management, but they require additional DLL files to be distributed or installed on the target system.
The GitHub repository "ottverse/ffmpeg-builds" provides regularly updated static and shared builds of FFmpeg for Windows 64-bit, with new releases every Wednesday by 9 PM IST.
The GitHub repository "BtbN/FFmpeg-Builds" also offers static Windows (x86_64) and Linux (x86_64) builds of FFmpeg, targeting Windows 7 and newer, and RHEL/CentOS 8 or newer.
The "BtbN/FFmpeg-Builds" repository provides detailed information on the differences between static and shared libraries, as well as guidance on when to use each type of library.
Static FFmpeg builds are typically preferred by end-users who want a self-contained and reliable executable, while shared builds are often preferred by developers who need more flexibility in managing dependencies.
The choice between static and shared FFmpeg builds may also depend on the target system's available disk space, memory constraints, and the specific requirements of the software or application using FFmpeg.
FFmpeg's build system allows for the compilation of both static and shared libraries, but enabling shared libraries will automatically disable the static ones due to the way MSVC and ICL handle DLL imports and exports.
Static FFmpeg builds may be larger in size but can be more suitable for deployment on systems with limited internet access or where the availability of specific DLL files cannot be guaranteed.
Shared FFmpeg builds can potentially offer better performance and resource utilization, as they allow for the sharing of common library code across multiple applications on the same system.
The "ottverse/ffmpeg-builds" repository provides detailed information on the specific commit IDs and branch versions used for their static and shared FFmpeg builds.
The "BtbN/FFmpeg-Builds" repository also offers builds targeting different versions of Windows and Linux distributions, allowing users to choose the most suitable build for their target environment.
Both the "ottverse/ffmpeg-builds" and "BtbN/FFmpeg-Builds" repositories provide build scripts and instructions, enabling users to create their own custom static and shared FFmpeg builds if desired.
The choice between static and shared FFmpeg builds may also depend on the licensing requirements of the project or application, as static builds can include components that require the GPL license, while shared builds may use more LGPL-licensed libraries.
FFmpeg's build system supports a wide range of configuration options, allowing users to customize the included codecs, features, and dependencies in both static and shared builds.
The performance difference between static and shared FFmpeg builds can vary depending on the specific use case and the overhead of dynamic library loading and linking.
Static FFmpeg builds may be preferred in environments with strict security policies or where the system administrator has full control over the target environment, as they reduce the risk of DLL conflicts or missing dependencies.
Shared FFmpeg builds can be more suitable for software distribution and deployment, as they allow for smaller download sizes and the ability to leverage system-wide DLL caching and sharing mechanisms.
