参照网上说明编译成功
播放本地部分文件出现声音卡顿，修改- (NSArray *) decodeFrames: (CGFloat) minDuration方法，
//if (_videoStream == -1) {

                        _position = frame.position;
                        decodedDuration += frame.duration;
                        if (decodedDuration > minDuration && ((_videoStream == -1) || (decodedDuration >= decodedVideoDuration) ))
                            finished = YES;
                    //}

声音不卡了，但是出现视频缓冲现象。
从io监视来看，本地文件io分布极度不均匀，经常是0，偶尔突发2M/s读写
内存也是忽高忽低，但是似乎没溢出
