In this document, terms such as first, second, third, etc. are used solely to distinguish one entity (or action) from another entity (or action) without necessarily requiring or implying any order or relationship between such entities (or actions). Fig. 2 is a flowchart of a video positioning playing method based on a user playing portrait according to an embodiment of the present application, the method includes the following steps:
s1: when a first user plays a first video file through application, determining that the first user belongs to a preset user play portrait database, wherein the total number of times of user history playing videos in the user play portrait database is greater than or equal to a preset threshold value; wherein a single video file in the application comprises a plurality of video clips, each video clip having at least one preset tag, the video clips with the same preset tag belonging to the same category;
S2: acquiring a historical clip playing heat value of a first user, wherein the historical clip playing heat value represents the historical playing heat of the user on video clips of different categories in the application; acquiring accumulated use frequency of a first user on a non-default playing mode in the playing process of video clips of various categories;
s3: according to the historical fragment play hotness value of the first user, ranking the hotness values of the video fragments of the categories in the application; video clips of a plurality of categories with the heat values sequenced are subjected to sequencing, a play mode sequence corresponding to each category is generated according to the accumulated use frequency of the first user in the non-default play mode corresponding to each category, and a play mode display label is generated for each play mode;
s4: determining the ordering of each video segment in the first video file based on the hotness value ordering, and determining the ordering of the play mode display tags under each video segment in the first video file based on the play mode ordering;
s5: and sequentially displaying each video clip in the first video file and the playing mode display tag under each video clip in the positioning play list of the first video file.
When a user requests to play a target video, sequencing the playing heat values of the fragments of different categories in all historical video fragments according to the user, sequencing all the fragments according to the use frequency of a non-default playing mode in the playing process under the sequencing, and generating a mode label; then, for the target video requested to be played by the user, the target video comprises a plurality of video clips, the labels (default labels and mode labels) corresponding to the clips of the target video are ordered according to the ordering mode, and the default labels and the ordering of the mode labels of the video clips are sequentially displayed in a positioning play list of the target video.
In different embodiments of the present application, the play heat value of the video clip can be counted in various ways, not limited to the play times, play time, average play time, play times or play time ratio, and the click frequency of slow play, mirror, and circulation buttons of each clip. For example:
clip play heat value = clip play count/total play count for each clip
Clip play heat value = clip play duration/video play duration
Segment play heat value = segment average play time length
By using the embodiment of the application, the video clips currently watched by the user can be sequenced based on the historical watching preference of the user, so that the real watching preference of the user can be fitted to the maximum extent, the user can quickly locate the playing position of real interest, and the use experience of the user is improved. The embodiment of the application is especially suitable for video playing occasions such as teaching videos, long videos and the like which comprise multiple video clips and have different content attributes of different clips, and can provide unexpected convenience for users.
It should be noted that, when the ranking of the playing heat value is performed, the objects to be ranked are a plurality of video clips in the first video file, the ranking is based on the historical playing heat value of each video clip, and the higher the heat value, the more popular the description is, and the higher the ranking order of the corresponding video clip is.
It should be noted that, when the playing mode ordering is performed, the ordered objects are still video clips, and the difference between the ordering and the hotness value ordering is that the playing mode ordering is based on the frequency (or called the call number) of the playing modes corresponding to each video clip, in other words, the playing mode ordering is based on the playing times of each video clip in different playing modes, so that the clips participating in the ordering may include a plurality of clips different from each other, or may include a plurality of the same clips in different playing modes. This will be illustrated and explained in detail hereinafter.
In some embodiments of the present application, the historical clip play heat value may be calculated using the following equation:
wherein (1)>For the first user to play the play heat value of the ith video clip in the total historical video,/for the first user to play the ith video clip>The total duration of playing the ith video clip for the first user,/for the first user>The total duration of the entire historical video is played for the first user.
Specifically, the first video file to be played may include a plurality of video clips, for example, the first video file may be segmented by a video dotting technique, and a segment mark may be added at a time of the first video file, so that the first video file may be divided into two video clips. Wherein a video clip may be simply referred to as a "clip," or may also be referred to as a "sub-video" of a first video file.
Illustratively, assuming that the first video file contains 9 segments in total, the heat value of the 6 th segment can be calculated according to the above formula as:
wherein->And playing the total duration of the 6 th video clip for the first user.
According to the formula, the playing heat value of all 9 video clips can be calculated, the popularity of each clip can be reflected through the heat value, and the higher the heat value of a clip is, the more popular the video content in the clip is. And sorting according to the heat value from high to low, namely finishing the sorting of the play heat values in the embodiment of the application.
In the embodiment of the application, besides sorting the clips according to the historical play heat value, the play modes used when each clip is played are considered, and the play modes are sorted according to the use frequency of the play modes. This will be explained in detail below.
For example, a play mode presentation tag in an application includes: a single mode tag and a combined mode tag; wherein the single mode tag comprises: slow play, mirror play and cyclic play mode labels; the combined mode tag includes: slow play and mirror play combination, slow play and cyclic play combination, mirror play and cyclic play combination, slow play, mirror play and cyclic play combination mode labels. It should be understood that, the playing modes mentioned in the embodiments of the present application may be various video playing modes that are already available in the market or not yet released in the market, and the present application is not limited to or limited by the specific form of the playing modes.
In some embodiments of the present application, when the playing modes under each video clip in the first video file are ordered according to the number of times of calling the playing modes, at least two cases may be:
case one: if the first video file comprises a first video clip, the first user uses the first playing mode in the playing process of the first video clip, the using times are K times, and K is larger than or equal to a preset threshold value, the first playing mode under the first video clip participates in the playing mode sequencing.
And a second case: if the first video file comprises a second video clip, a second playing mode is used in the playing process of the second video clip, the using times are R times, and R is smaller than a preset threshold value, the second playing mode under the second video clip does not participate in the playing mode sequencing.
For example, the user a often uses the APP to play the video, and according to the log data, it is obtained that the number of times the user a plays the video in the APP exceeds a preset statistical threshold (for example, 1000 times), that is, the number of times the user a plays the video is higher than the threshold, so that the play behavior preference of the user can be categorized, and thus the user is counted in the play portraits of the user.
It is assumed that the first video file is a complete dance video of modern dance, which includes a plurality of segments, such as a start segment, a dance segment, etc. According to log data, wherein the collar segment obtains a higher playing frequency (for example, 1400 times for the history playing frequency of the collar segment of the mirror and 1300 times for the history playing frequency of the collar segment of the loop playing) in two playing modes (for example, mirror and loop playing), the preset statistical threshold value (for example, 1000 times) is exceeded, in this case, the system may generate two playing mode display labels for the collar segment, for example: "dancing segment-mirror", "dancing segment-loop play", and when the play modes are ordered, the rank of "dancing segment-loop play" is higher than "dancing segment-mirror".
For clips whose frequency of use is below the threshold, no secondary ordering is performed, excluding them from the play mode ordering.
Here, in view of the fact that no separate mirror segment or cyclic segment exists in the original modern dance video, in the embodiment of the present application, a positioning playlist of the original video is expanded to a certain extent, that is, a playing mode display tag of an independent mirror segment (or cyclic segment, or segment of other modes) is additionally added in addition to a default tag of the original video, so that it can be understood that the embodiment of the present application expands a playing function based on the original video, and an expanded video segment in a multi-playing mode can be explicitly added in the playlist, so that a user can browse and position the video fast, and the video segment can be played by one key, and the operation is convenient.
In the above example, if the number of play times of the play segment in the slow play mode in the dance video of the modern dance is 800 and is lower than 1000 times specified by the threshold value, it is indicated that the play amount of the play segment played in the slow play mode is smaller, that is, less attention is paid to the user, the play mode ordering is not performed on the play segment in the slow play mode, the system will not generate the display tag and the extended video segment, and the slow play category recommendation will not be displayed to the user.
Regarding the presentation tags, the system may set a default presentation tag, i.e., a default play mode tag, for each video clip, containing the basic information of the clip, and be a conventional play mode without special effects, such as "start-up clip of modern dance", "neck-dance clip of modern dance". When the user clicks the pre-default play mode tab, the player plays the video clip in a regular mode, such as regular playing of a dance clip in a dance video file of a modern dance.
Unlike the default play mode tab, when the user clicks the show tab with play mode, the player plays the present video clip in the corresponding mode, e.g., plays the dance clip in mirror.
The default playing mode label and the playing mode display label can be sequentially displayed in the positioning playing list of the original complete video, so that a user can conveniently and quickly select to play.
Various implementations and technical advantages of the video clip ordering method according to the embodiments of the present application are described above through various embodiments. The following describes the specific operation of the embodiment of the present application in detail with reference to specific examples.
Example 1
As an example, zhang III is an old user of the video application APP, loves to watch the teaching video of dance class, user playing portraits generated based on statistics of log data of Zhang III are stored in the system, video playing preference of Zhang III is reflected, for example, playing heat values of historical video clips of Zhang III can be calculated according to the playing portraits (or log data), and the historical use frequency of Zhang III in different video clips can be counted and ranked according to the category of the clips.
In the case of dance teaching video, i.e., video content is video for dancer or dancer to demonstrate, teach, and guide dance movements, such video typically includes a plurality of video clips, which may be defined as different categories according to clip content, such as front dance demonstration teaching clips, back dance demonstration teaching clips, group dance movement demonstration teaching clips, and the like.
