video encoding stream comprises
Examples with "video encoding stream comprises" and their translation in Chinees
Further, the video encoding stream comprises a plurality of groups of pictures. Each GOP is a picture set consisting of an I frame, as well as a refreshment P frame and a common P frame that are located after and have the direct or indirect reference relation with the I frame.
进一步地，所述视频编码码流中包括多个图像组，每个图像组包括一个I帧与其后同其存在直接或间接参考关系的刷新P帧、普通P帧组成的图像集合。
If the stream is determined to comprise the stream tag, the type of each encoded frame can be identified quickly by further determining the packaging layer of the video encoding stream comprises the frame tag, i.e., the tags with type information added for the encoded frames.
其中，如果确定码流包含码流标记，进一步的判断确认在视频编码码流的封装层还包含帧标记即为编码帧添加的带有类型信息的标记，则可以快速地识别出每个编码帧的类型。
Determining whether a packaging layer of the video encoding stream comprises the stream tag is to determine whether the video encoding stream is generated by the encoding method (Embodiment 1) of the video encoding stream provided by the invention.
其中，判断视频编码码流封装层是否包含码流标记，也即是判断该视频编码码流是否为经过本发明的视频编码码流的编码方法（实施例一）所生成的视频编码。
Group of pictures: the video encoding stream comprises a plurality of groups of pictures. Each GOP comprises a plurality of encoded frames having reference relation.
图像组：视频编码码流中包括多个图像组，在每个图像组中包括存在参考关系的多个编码帧，
That is to say, when the video encoding stream comprises the stream tag, and is further provided with the frame tags, the stream is generated by the encoding method of the invention, and the encoded frames of the stream are further provided with the frame tags comprising the type information of the encoded frames.
也就是说，当所述视频编码码流包含码流标记、并且该码流中还具有帧标记时，即该码流由本发明的编码方法产生，同时，其编码帧还具备相应的包含该编码帧的类型信息的帧标记。
In one embodiment, the code stream information of the video encoding stream comprises the code stream frame rate information, the code stream frame rate information is a measure for measuring the number of display frames, namely frames per second (referred to as FPS) or "Hertz" (Hz).
在一个实施方式中，视频编码码流的码流信息中包括了码流帧率信息，该码流帧率信息是用于测量显示帧数的量度，即每秒显示帧数（Frames per Second，简称：FPS）或"赫兹"（Hz）。

As shown in Fig. 4, the playing control method of the video encoding stream of the invention comprises the following steps
如图4所示，本发明的视频编码码流的播放控制方法包括下述步骤：
As shown in Figure 7, the video encoding stream may comprise a plurality of GOPs, while each GOP may comprises a number of encoded frames having reference relation, wherein the encoded frames include I frame, common P frame and refreshment P frame.
参见图7所示，在该视频编码码流中，可以包括多个图像组GOP；而在每个图像组中，可以包括存在参考关系的多个编码帧；其中，编码帧的类型包括：I帧、普通P帧和刷新P帧。
A first determination module 910, configured to obtain the video encoding stream to be accessed and determine whether the stream comprises a stream tag.
第一判断模块910，用于获取待访问的视频编码码流，以判断该码流是否包含码流标记。
If the stream comprises the stream tag but is not provided with the frame tags, the stream is generated by the encoding method provided by the invention, so that the I frame, the refreshment P frame and the common P frame exist in the video encoding stream, and only the stream tag rather than the frame tags is added in the encoding process.
这种码流包含码流标记但不具有帧标记的情形，说明码流采用的是本发明的编码方法生成，因而，视频编码码流中存在I帧、刷新P帧和普通P帧，只是在编码过程中只添加了码流标记，而未添加帧标记，
Since each index node information or each index record of the index comprises the position information, the timestamp information and the number information of each frame, the encoded frames in the video encoding stream can be located quickly.
由于该索引的各个索引节点信息或者说索引记录中包含各个帧的位置、时间戳、帧号信息，从而其可以用于快速定位视频编码码流中编码帧的位置。
If the packaging layer comprises the stream tag, the video encoding stream is generated in an encoding manner provided by Embodiment 1.
如果包含码流标记，则表示该视频编码码流为实施例一编码方式生成的码流。
If the steam does not comprise the stream tag, the video encoding stream is a video encoding stream of other type (for example, other known stream in the prior art), and is not generated by the encoding method provided by the invention, so that the type of each encoded frame cannot be identified directly.
其中，如果不包含码流标记，则表示视频编码码流为其他方式（例如现有技术其他已知）的视频编码码流，非本发明的编码方法产生的码流，从而不能直接识别出每个编码帧的类型。
