 S206: Determine whether the video encapsulation format of the video content data packet included in the associated video segment is the same as the video encapsulation format of the current video content data packet, and if yes, go to S207, if no, go to S208.

 Specifically, the commonly used video package formats generally include ".flv", ".mp4", "3gp", and ".ts", and a keyword for identifying a video encapsulation format is generally set in the video content data packet, and is parsed. The header information of the video content data packet can obtain the corresponding video encapsulation format, which is used as the encapsulation format of the current video segment. Of course, it is also possible to carry the identification video in the HTTP header field of the video request data packet and the video response data packet. The encapsulation format keyword can also determine the video encapsulation format by parsing the HTTP header field of the video request packet and/or the video response packet.

 S207: Combine the current video request packet, the current video response packet, and the current video content data onto the associated video segment.

 S208: The current video request data packet, the current video response data packet, and the current video content data are used as a new video segment.

 S209: Determine a KQI of the video service according to the obtained video segment.

Specifically, in the embodiment of the present invention, when determining that the encapsulation format of the video segment corresponding to the current video data packet is a non-TS format, such as video formats such as "ilv", ".mp4", and "3gp", the video data packet may be determined. Whether the begin, start, range, and the like identify the keyword at the beginning of the video, and determine whether the current video segment is a new video by using the value of the keyword that starts the video, for example, when begin, start, range is 0 or 13 , the video clip is a new video, and then step S405 is performed, and the video clip is used as a new video stream. If it is determined by the value of the keyword that starts the video that the current video segment is not a new video, then the process proceeds to S406, the associated video corresponding to the video segment is determined, and the current segment is associated with the associated video segment.

S405: Record the current video clip as a new video clip. The video segment to be combined is determined, and the current segment is associated with the determined video segment to be combined. Specifically, when the video request data packet included in the current video segment is a redirect request data packet, the video segment to be combined is determined in the associated video segment with the same video encapsulation format as the video content data packet included in the current video segment. And the uniform resource locator URL value carried in the header information carried in the header information of the response packet included in the video segment to be combined and the header information of the video request packet included in the current video segment Equal, combines the current video clips onto the determined video clips to be combined.

 The video encapsulation format of the video content data packet included in the current video segment is in the TS format, and when the video segment data packet included in the current video segment carries the content segment keyword, the video content data packet included in the current video segment The video segment to be combined is determined in the associated video segment with the same video encapsulation format, wherein the video request packet included in the video segment to be combined carries a content index keyword corresponding to the content segment keyword, and the current The video clips are combined onto the determined video clip to be combined.

 The video encapsulation format of the video content data packet included in the current video segment is in the TS format, and when the video request packet included in the current video segment carries the content index keyword, the video content data packet included in the current video segment The video segment to be combined is determined in the associated video segment with the same video encapsulation format, wherein the video request packet included in the video segment to be combined carries a bandwidth index keyword corresponding to the content index keyword, and the current The video clips are combined onto the determined video clip to be combined.

When the video encapsulation format of the video content data packet included in the current video clip is in a non-TS format, determining that the value of the keyword used to identify the start of the video carried in the video request data packet included in the current video clip is not used to identify new When the value of the video is started, it is determined that the combination is the same as the video encapsulation format of the video content data packet included in the current video segment. In the video association process of the embodiment of the present invention, the foregoing steps do not exist. In order, and not necessarily every step exists, for example, S401 is optional, in the judgment video Before the video encapsulation format of the fragment is the streaming media TS format, it is determined whether the current video segment is a redirected video segment.
