  • 略

2.使用whisper初始化上下文，并根据给定的模型文件和参数进行配置

  • webassembly003 whisper.cpp的main项目-2:根据给定的模型文件和参数进行配置

3.对输入文件列表进行循环处理

3.1解析参数

        const auto fname_inp = params.fname_inp[f]; // "/home/***/whisper.cpp-1.5.0/samples/jfk.wav"const auto fname_out = f < (int) params.fname_out.size() && !params.fname_out[f].empty() ? params.fname_out[f] : params.fname_inp[f]; // "/home/***/whisper.cpp-1.5.0/samples/jfk.wav"
