Description: FFmpeg provides Windows32 bit, Windows 64 bit and MacOS applications. For each operating system, three modes of Static/Shared/Dev are provided: Static uses static library loading, the downloaded file does not contain dynamic library, and the volume of the whole program will be larger; Shared uses dynamic library loading, and the downloaded file contains dynamic link libraries, which are represented as dll libraries and lib libraries on Windows Dev provides the FFmpeg development package, which can be understood as the development of SDK for programmers!
