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! |
