CEF可以通过命令行设置加载flash插件，有两种方式:

*  在程序启动时添加命令行参数

`cef.exe --ppapi-flash-path=ppflash/18_0_0_209/pepflashplayer32_18_0_0_209.dll --ppapi-flash-version=18.0.0.209`

*  `override` OnBeforeCommandLineProcessing函数

class CCefClientApp : public CefApp, public CefBrowserProcessHandler
    {
    public:
        CCefClientApp();
        ~CCefClientApp();
    
        // CefApp methods:
        virtual CefRefPtr<CefBrowserProcessHandler> GetBrowserProcessHandler() override 
        {
            return this;
        }
    
        virtual void OnBeforeCommandLineProcessing(const CefString& process_type, CefRefPtr<CefCommandLine> command_line) override;
    
        // CefBrowserProcessHandler methods:
        virtual void OnContextInitialized() override;
    
    private:
        // Include the default reference counting implementation.
        IMPLEMENT_REFCOUNTING(CCefClientApp);
    
    private:
    
    };

--------------------

void CCefClientApp::OnBeforeCommandLineProcessing(const CefString & process_type, CefRefPtr<CefCommandLine> command_line)
    {
        //加载flash插件
        command_line->AppendSwitchWithValue("--ppapi-flash-path", "ppflash/18_0_0_209/pepflashplayer32_18_0_0_209.dll");
        //manifest.json中的version
        command_line->AppendSwitchWithValue("--ppapi-flash-version", "18.0.0.209");
    
    
    }
