AVSampleBufferDisplayLayer 更新 vi

    参考 stackoverflow

    setting the AVPlayerLayer's bounds to the AVPlayerLayer's bound seemed to do the trick. although i don't really get why.

    self.displayLayer.videoGravity = gravity;
    //通过改变bounds, 触发gravity 生效
    CGRect bounds = self.displayLayer.bounds;
    self.displayLayer.bounds = CGRectZero;
    self.displayLayer.bounds = bounds;
