Play Audio with Netbeans and linking with LibVLC

In this blog i will demonstrate how to play mp3 file using simple LibVLC and Neatbeans on ubuntu.

  1. First you need to install LibVLC into your system. if you not, follow how to install tutorial to install LibVLC.
  2. Open Netbeans and create new C application.

    after project create, main file looks like this.

  3. Replace this main.c file with below content.
                #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, "/home/audio.mp3");
                    // create a media play playing environment
                    mp = libvlc_media_player_new_from_media(m);
                    // no need to keep the media now
                    // play the media_player
                    sleep(100);//play the audio 100s
                    // stop playing
                    // free the media_player
                    return 0;
  4. You need place mp3 file named audio.mp3 in your home directory.
  5. Try to run the project by clicking the Netbeans Run button.
    • But you will get this kind of error. It is because Project must be link to the LibVLC in netbeans.
                      /home/rukshan/NetBeansProjects/Audio/main.c:19: undefined reference to `libvlc_new'

    • To link it to the LibVLC follow the steps.
        • right click on the project Audio and select properties.
        • Select Linker menu from left pane.
        • Click the browse button right to the Libraries from the right pane.
        • from the poped window choose the usr/lib/libvlc.so by clicking add library.
      • Clicking ok exit from the windows.
  6. Run the project by clicking the Netbeans Run button again.
  7. Audio projct will run succesfully.
