[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0043] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0044] In view of the problems in the background technology, the embodiments of the present disclosure provide a video playback method, device, equipment and storage medium. Specifically, the playback time of each switched video is obtained, wherein the video is pushed by an external video platform; according to the playback time of each switched video, the user's preference for different video types in the video types of each switched video is calculated; the videos belonging to the target video type in the to-be-played list are deleted, wherein the videos in the to-be-played list are pushed by an external video platform, and the target video type is a video type whose preference is lower than a preset threshold; and the video is played according to the deleted to-be-played list.

[0045] In this way, when playing videos pushed by external video platforms, the user's preference for different types of videos can be determined based on the playback time of each switched video, and then the videos that the user does not like in the to-be-played list can be deleted based on this, and the videos can be played according to the deleted to-be-played list, quickly skipping the content that the user is not interested in, thereby improving the user experience.

[0046] The video playback method, device, equipment and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings through specific embodiments.

[0047] Figure 1 A flow chart of a video playback method provided by an embodiment of the present disclosure is shown. Figure 1 As shown, the video playing method 100 can be applied to a client, and includes the following steps:

[0048] S210, obtaining the playing time of each switched video.

[0049] The video is pushed by an external video platform, which is a video platform other than the video platform corresponding to the client, and can be a representative platform such as a TV station or an online video platform.

[0050] S220, calculating the user's preference for different video types among the video types of the switched videos according to the playing time of each switched video.

[0051] In some embodiments, the user's preference for different video types among the video types of the switched videos may be calculated in real time based on the playback duration of the switched videos.

[0052] The number of video switching times can also be counted, and it is determined at preset time intervals whether the number of video switching times counted within the preset time is greater than or equal to a preset threshold. If it is greater than or equal to the preset threshold, the user's preference for different video types in the video types of the switched videos is calculated based on the playback time of each switched video. In this way, when the user switches videos too frequently within a cycle, the user's preference for different video types in the video types of the switched videos can be calculated in a timely manner, thereby reducing the usage of computing resources.

[0053] As an example, the switched videos can be grouped according to their video types, and the average playback time of each group can be calculated based on the playback time of each video in each group. The average total playback time of each group can be calculated based on the total time of each video in each group. The average playback time of each group can be divided by the corresponding average total time to quickly obtain the user's preference for the video type corresponding to each group, and then the user's preference for different video types in the video types of the switched videos can be determined.

[0054] For example, as of now, there are 10 videos that have been switched, namely video 1 to video 10. Among them, the playing time of videos 1-10 is 6s, 8s, 10s, 4s, 10s, 4s, 6s, 60s, 40s, 50s respectively; the total time of videos 1-10 is 400s, 400s, 700s, 300s, 400s, 500s, 400s, 600s, 400s, 500s respectively; the video type of videos 1-3 is news, the video type of videos 4-7 is drama, and the video type of videos 8-10 is animation. Optionally, the video type here can be further refined to specific video themes, video names, etc., which are not limited here.

[0055] At this time, the switched videos are grouped according to their video types, and groups 1-3 can be obtained. Among them, group 1 includes videos 1-3, group 2 includes videos 4-7, and group 3 includes videos 8-10. Next, the average playback time and average total time corresponding to each group are calculated. Among them, the average playback time of groups 1-3 is 8s, 6s, and 50s respectively; the average total time of groups 1-3 is 500s, 400s, and 500s respectively. Then the average playback time corresponding to each group is divided by the corresponding average total time to obtain the corresponding quotient of each group, which is 0.016, 0.015, and 0.1 respectively. The quotient corresponding to each group can be directly used as the user's liking for the video type corresponding to each group, that is, the user's liking for news is 0.016, the liking for drama is 0.015, and the liking for animation is 0.1.

[0056] As another example, the comment information (such as barrage) entered by the user when playing the video can also be obtained, and the user's preference for different video types among the video types of the switched videos can be calculated based on the playback duration and comment information of each switched video.

[0057] In this way, the dimension of user comments can be introduced on the basis of the playback duration, thereby more comprehensively calculating the user's preference for different video types among the video types that have been switched.

[0058] For example, keywords can be extracted from the comment information of each switched video, and the user's preference level for the corresponding video type can be determined based on the keywords of videos of the same type. For example, the keywords of videos of the same type are input into a pre-trained preference evaluation model to obtain the user's preference level for the corresponding video type, and the coefficient corresponding to the preference level is multiplied by the corresponding quotient (see the above example, that is, the quotient of the group corresponding to the corresponding video type) to obtain the user's preference degree for the corresponding video type, and then the user's preference degree for different video types among the video types of the switched videos can be determined.

[0059] S230, deleting the videos of the target video type in the to-be-played list.

[0060] The videos in the to-be-played list are pushed by an external video platform, and the target video types are video types whose popularity is lower than a preset threshold, that is, video types that the user is not interested in.

[0061] Referring to S220, the user's preference for news is 0.016, the preference for drama is 0.015, and the preference for animation is 0.1. At this time, the preset threshold may be 0.05, so the target type is news and drama, and the videos belonging to news and drama in the subsequent to-be-played list will be deleted. Optionally, before deleting, the user may be prompted "whether to collapse this type of video", and if the user chooses to collapse, the video will be deleted.

[0062] S240, playing the video according to the deleted to-be-played list.

[0063] In the embodiments of the present disclosure, when playing videos pushed by an external video platform, the user's preference for different types of videos can be determined based on the playback duration of each switched video, and based on this, the videos that the user does not like in the to-be-played list can be deleted, and the videos can be played according to the deleted to-be-played list, thereby quickly skipping the content that the user is not interested in, thereby improving the user experience.

[0064] In some embodiments, if the playing time of the current video is greater than a preset threshold, that is, the user is interested in the current video, it can be detected whether there is a target video related to the current video (a subsequent video of the current video) in the to-be-played list;

[0065] If there is a target video related to the current video, put it at the top of the to-be-played list;

[0066] If there is no target video related to the current video, the target video is obtained from the corresponding external video platform (a video platform that can provide the target video) and placed at the top of the to-be-played list.

[0067] In this way, the subsequent videos of the video that the user is interested in can be placed at the front of the to-be-played list, so that after the interested video is played, the corresponding subsequent videos can be played immediately, thereby further improving the user experience.

[0068] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously.
