GOP = Group of Picture
URL: https://en.wikipedia.org/wiki/Group_of_pictures
In video coding, a group of pictures, or GOP structure, specifies the order in which intra- and inter-frames are arranged. The GOP is a collection of successive pictures within a coded video stream. Each coded video stream consists of successive GOPs, from which the visible frames are generated. Encountering a new GOP in a compressed video stream means that the decoder doesn't need any previous frames in order to decode the next ones, and allows fast seeking through the video.
谷歌翻译：
在视频编码中，一组图片或GOP结构指定帧内和帧间排列的顺序。 GOP是编码视频流内的连续图像的集合。 每个编码视频流由连续的GOP组成，从中生成可见帧。 在压缩视频流中遇到新的GOP意味着解码器不需要任何先前的帧以便解码下一帧，并允许快速搜索视频。

Video data in TS2 does not start with a closed GOP. 是 PlayItem 选择无缝链接后，大金检测视频开头不符合一个完整的 GOP 时出现的报错！
大意是这个视频开头不是一个正确的起始帧！而是切在了 a group of pictures 的中间部分！
无缝链接，要求视频起始帧是一个完整的GOP，这样才符合无缝组合的要求！
遇到这种，选择有缝链接就能解决报错！只要播放器和碟机测试播放肉酱衔接部分时，没有出现问题就行了！ |
