int libvlc_NothingSpecial=0;
    int libvlc_Opening=1;
    int libvlc_Buffering=2;
    int libvlc_Playing=3;
    int libvlc_Paused=4;
    int libvlc_Stopped=5;
    int libvlc_Ended=6;
    int libvlc_Error=7;

    /**
     * Returns true if any media is playing
     */
    public native boolean isPlaying();
 

可什麼是is playing呢？在vlc 原始碼中，能看到

(state == libvlc_Opening) || (state == libvlc_Buffering) ||
           (state == libvlc_Playing)

有時候我們的需求更細緻，如果要在網路視訊播放之前加上一個ProgressBar，視訊開始播放就取消ProgressBar，這時就必須知道libvlc_Playing何時出現。

為了獲得更細分的狀態，只有自己修改libvlcjni.c了，在該檔案最後加上

jint Java_org_videolan_vlc_LibVLC_getState(JNIEnv *env, jobject thiz)
{
    libvlc_media_list_player_t *mp = getMediaListPlayer(env, thiz);
    if (mp){
        libvlc_state_t state=libvlc_media_list_player_get_state(mp);
        return (jint)state;
    }
    else
        return -1;
}
 

    public native int getState();

例子如下，

        load(url);
        loadingDialog = ProgressDialog.show(this, "", "載入中，請稍等 …", false, true);
        new Thread(new Runnable() {
            @Override
            public void run() {
               while (true) {
                   try {
                       Thread.sleep(1000);
                       Log.d(TAG,"progress dialog():"+mLibVLC.getState());
                       if(mLibVLC != null &&mLibVLC.getState()==LibVLC_State.libvlc_Playing){
                           loadingDialog.dismiss();
                           break;
                       }
                   } catch (InterruptedException e) {
                       e.printStackTrace();
                   }
               }
            }
        }).start();
