No.packagesis just a staging dir and should not be used. What you should use is the vcpkg cmake toolchain. It is not just setting up paths but also loading wrappers for CMake modules. Really: vcpkg portffmpeginstalls a wrapper and a Find module which enablesfind_package(FFMPEG)to work....

通过AVCodecFindDecoder() 函数查找 MPEG 音频解码器并得到其指针,如果为空则表示未找到对应的解码器。接着调用 AVParserInit() 函数初始化一个解析器,用于从输入文件中解析出音频数据帧。同时也需要分配一个编解码器上下文(AVCodecContext)对象,并调用 AVCodecOpen2() 函数打开编解码器。
