I am an average c/c++ programmer. Recently i took a project to make a media player with a smart playlist. So it will work like zune's SmartDj. I have decided to use libvlc for playing. i have never coded an open source software ever. So i know nothing about git and all. Please help me to write at least a c program to play a mp3 file.

我应该在哪里开始呢？

和如何从MP3中提取歌曲的艺术家和其他信息文件本身？

and how to extract song's artists and other information from the mp3 file itself ?

问候。

推荐答案

请确保您已经安装了以下软件包（否则安装）：

be sure that you have installed the following packages (else install it):

$ apt-get install libvlccore-dev libvlc-dev

test.c的：

#include <stdio.h>
#include <stdlib.h>

#include <vlc/vlc.h>

int main(int argc, char **argv)
{
    libvlc_instance_t *inst;
    libvlc_media_player_t *mp;
    libvlc_media_t *m;

    // load the vlc engine
    inst = libvlc_new(0, NULL);

    // create a new item
    m = libvlc_media_new_path(inst, "path to MP3 file");

    // create a media play playing environment
    mp = libvlc_media_player_new_from_media(m);

    // no need to keep the media now
    libvlc_media_release(m);

    // play the media_player
    libvlc_media_player_play(mp);

    sleep(10);

    // stop playing
    libvlc_media_player_stop(mp);

    // free the media_player
    libvlc_media_player_release(mp);

    libvlc_release(inst);


    return 0;
}

如何链接和编译：

$ gcc $(pkg-config --cflags libvlc) -c test.c -o test.o

$ gcc test.o -o test $(pkg-config --libs libvlc)
