我想做一个播放器，已经适配了vlc，现在有一些问题1.视屏只播放前面一段2.控制台输出报错[04215c58] mmdevice audio output error: cannot initialize COM (error 0x80010106)3.我想让他在easyx窗口，我获得了窗口句柄，但不知添加到哪4.我的程序附近包含了vlc安装目录的所有文件夹和dll。

最后附上我的代码：

#include <stdio.h>
#include "vlc/vlc.h"
#include <windows.h>
#pragma comment(lib, "libvlc.lib")
#pragma comment(lib, "libvlccore.lib")
using namespace std;
HWND hwnd = GetHWnd();
int main(int argc, char* argv[])
{
    initgraph(1600, 900, EW_SHOWCONSOLE);
    libvlc_instance_t* inst;
    libvlc_media_player_t* mp;
    libvlc_media_t* m;

    inst = libvlc_new(0, NULL);        /* Load the VLC engine */
    m = libvlc_media_new_path(inst, "test.mp4");  // 必须为英文路径  
    mp = libvlc_media_player_new_from_media(m);    /* Create a media player playing environement */
    libvlc_media_release(m);           /* No need to keep the media now */

    // 播放文件
    libvlc_media_player_play(mp);      /* play the media_player */
    Sleep(100 * 1000);                 /* Let it play a bit */

    libvlc_media_player_stop(mp);      /* Stop playing */
    libvlc_media_player_release(mp);   /* Free the media_player */
    libvlc_release(inst);
    return 0;
}

请大家解答。
