MobileVLCKit如何播放带有空白帧的视频流？

我的代码如下：

NSMutableDictionary *mediaDictionary = [[NSMutableDictionary alloc] init];
[mediaDictionary setObject:@"50000" forKey:@"network-caching"];
self.vlcplayer = [[VLCMediaPlayer alloc] init];
// self.vlcplayer = [[VLCMediaPlayer alloc] initWithOptions:[NSArray arrayWithObject:@"-vvvv"]];
[self.vlcplayer setDelegate:self];
NSURL *url = [NSURL URLWithString:self.videoURL];
self.vlcplayer.media = [VLCMedia mediaWithURL:url];
[self.vlcplayer.media addOptions:mediaDictionary];
self.vlcplayer.drawable = _PlayView;
[self.vlcplayer play];

播放的效果是视频和音频不同步；视频流的帧率为30，其中5帧为空白帧；播放没有空白帧的视频流时，可以正常播放； 如何设置以空白帧播放视频流？谢谢！
