如何用c ++在vlc中播放mp3文件

Question

I have to write a c++ code which plays a specified song in VLC. I've made some research but i didn't find too much.

#include <iostream>
#include <string>
//#include "VLCWrapper.h"
//#include<libvlccore.dll>
//#include<libvlc.dll>
using namespace std;
int main() 
{

    cout << "Welcome to VLC launcher program!" << endl;
    cout << "Please enter a filename: ";
    string filename;
    getline(cin, filename);

    string comm = "vlc \"";
    comm += filename + "\"";
    system(comm.c_str()); //call VLC with the file "filename"
    return 0;
 }

This is what i found, but when i compile appears 'vlc' is not recognized as an internal or external command operable program or batch file. I need some help, please.

Most likely you don't have vlc in path, since when I compile it

(had to add this)

#include <cstdlib>

it runs fine (I compiled it with g++ ):

$ ./a.out 
Welcome to VLC launcher program!
Please enter a filename: Darkside.mp4

You could try to replace vlc with the full path (eg. /usr/bin/vlc )...

In case you are on Windows (poor you), it will be the same, just google the "is not internal or external command" and there will be some tips on how to fix it.

Also, you will need vlc.exe probably, I have never used command line on Windows, so not sure how it works there.
