如何使用libvlc播放RTSP流

Question

我正在尝试使用libvlc播放RTSP流。下面是我的代码：

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    const char* fileName = "rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov";
    int windId = this->winId();

    libvlc_instance_t *instance = libvlc_new(0, NULL);
    libvlc_media_t *vlcMedia = libvlc_media_new_location(instance, fileName);
    libvlc_media_player_t* player = libvlc_media_player_new_from_media(vlcMedia);

    libvlc_media_player_set_xwindow(player, windId);
    libvlc_media_player_play(player);
}

问题是libvlc会像这样向服务器发送一个SETUP命令：

SETUP rtsp://184.72.239.149:554/vod/mp4://bigbuckbunny_175k.mov RTSP/1.0

vlc播放器发送的是：

SETUP rtsp://184.72.239.149:554/vod/mp4://bigbuckbunny_175k.mov/trackID=0  
SETUP rtsp://184.72.239.149:554/vod/mp4://bigbuckbunny_175k.mov/trackID=1 

Answer 1

libvlc中有多个RTSP访问插件。确保您使用的是live555而不是realrtsp。
