Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the video playing process, a plurality of playing speeds are usually set for users to select, and the users can adjust the playing speed according to their own preferences. However, the playing speed is continuously adjusted in the process of watching the video, so that the operation of a user is inconvenient, and the watching experience is influenced. According to the technical scheme provided by the embodiment of the disclosure, the plot information of the video to be played and the video clips corresponding to the plot information are obtained, wherein the video to be played comprises the video clips; acquiring preference information of a user; acquiring the playing speed of each video clip according to the plot information and the preference information; and playing the video to be played according to the playing speed. The playing speed of each video clip is obtained according to the plot of each video clip in the video to be played and the emotional preference of the user, so that the playing speed of each video clip in the video to be played meets the requirements of the user, manual adjustment of the user is not needed, and the user experience is improved.
Fig. 1 is a flowchart illustrating a video playing method according to an exemplary embodiment, where, as shown in fig. 1, the video playing method includes steps 101-104:
in step 101, episode information of a video to be played and video clips corresponding to the episode information are obtained.
The video to be played comprises one or more video clips. The episode information for each video clip may be used to indicate the emotion of the video clip to the viewer.
Here, two specific examples are listed to explain how to acquire scenario information:
in a first example, obtaining episode information of a video to be played and video clips corresponding to the episode information includes: and identifying the content of each video clip in the video to be played to acquire plot information and video clips.
The emotion tendency of the video clips can be accurately reflected by the plot information acquired by identifying the content of each video clip in the video to be played.
In a second example, obtaining episode information of each video clip of at least one video clip of a video to be played includes: acquiring at least one piece of bullet screen information of a video clip; and generating the plot information of the video clip according to at least one piece of bullet screen information of the video clip.
The plot information of each video clip is generated according to the barrage information, because the number of the audiences sending the barrage is more and more, the feeling and the sense of the audience brought by each video clip can be objectively reflected.
For example, taking the second example as an example, 10 emotion types may be set, and for a video segment, the types of emotions expressed by each piece of barrage information of the video segment may be analyzed, the number of pieces of barrage information of each emotion type may be counted, and the emotion type with the largest number of pieces of barrage information may be determined as the emotion type of the video segment and generating episode information.
For another example, 10 emotion types may be set, the number of pieces of barrage information for each emotion type may be counted as a score for each emotion type, and the scenario information of the video clip may be generated.
Of course, this is merely an example and does not represent a limitation of the present disclosure.
In step 102, preference information of a user is acquired.
The preference information of the user is used to indicate the emotional preference of the user.
In one embodiment, obtaining preference information of a user includes: acquiring historical data of a video watched by a user; determining emotional preference of the user according to the historical data and generating preference information.
The history of the user viewing the video may include the length of time the user viewed the video of at least one emotion type, the playing speed, etc. The preference information of the user is generated according to the historical data of the video watched by the user, and the user does not need to manually set, so that the operation of the user is further simplified, and the user experience is improved.
In another embodiment, obtaining user preference information comprises: and receiving preference information input by a user.
The user directly inputs the preference information, so that the calculation amount of the device is reduced, and the user can more accurately reflect the requirements of the user by setting by himself.
It should be noted that there is no sequence between step 101 and step 102, and the steps may be executed simultaneously, and after step 101 and step 102, the method further includes step 103 and step 104:
in step 103, the playing speed of each video clip is obtained according to the episode information and the preference information.
In one embodiment, obtaining the playing speed of each video clip according to the episode information and the preference information includes: acquiring a matching value of each video clip, wherein the matching value of each video clip is used for indicating the matching degree between the plot information and the preference information; and acquiring the playing speed according to the matching value, wherein the matching value and the playing speed are in a negative correlation relationship.
The plot information of each video clip is matched with the preference information to obtain a matching value, so that the matching degree between the plot information of each video clip and the preference of a user can be obtained, the set playing speed is more in line with the subjective requirements of the user, and the user experience is improved.
The matching value of each video clip is obtained, and there are multiple application scenarios for obtaining the playing speed according to the matching value, and here, two specific application scenarios are listed for description:
in a first application scenario, the plot information of each video segment includes a score of at least one emotion, the score is used for indicating the intensity of one emotion in the video segment, and the user preference information includes the user preference for at least one emotion;
acquiring a matching value of each video clip, wherein the method comprises the following steps: weighting the score of at least one emotion of each video segment according to the preference of the user for at least one emotion to obtain a weighted value of at least one emotion of each video segment; and determining the matching value of each video segment according to the weighted value of at least one emotion of each video segment.
Each video clip can be represented by one or more emotion scores, so that the emotion feelings brought to audiences by one video clip are reflected comprehensively, and then the matching values are determined by weighting the video clips according to the emotion preferences of the users, so that the video clips are matched with the emotions of the users more accurately, and the emotion preferences of the users can be more accurately approached.
Here, a specific example is illustrated, for example, as shown in fig. 2, fig. 2 is a schematic diagram illustrating a matching value calculation process according to an exemplary embodiment, where a target video segment is taken as an example, the target video segment is any one of at least one video segment of a video to be played, and the target video segment may include three emotional scores, namely 20 scores for making a beat, 30 scores for hurting a heart, and 15 scores for fear; the preference degrees of the user for the three emotions are respectively 10 for the fun, 0 for the hurt and-5 for the frightening; the weighting of the scores of the three emotions can be realized by respectively multiplying the scores of the three emotions by the preference of the user for the three emotions and calculating the weighted values of the three emotions to be 200, 0 and-75 respectively; the weighted values of the three emotions are added to obtain a matching value of the target video segment of 125. Of course, the examples herein are only for illustrating the implementation process of the present solution, and do not represent that the present disclosure is limited thereto, and the processes of setting the preference degree, calculating the weighted value, and calculating the matching value may be implemented in other ways, and the present disclosure does not limit the present disclosure.
In another embodiment, the episode information for each video clip indicates an emotion type of the video clip, and the user preference information includes at least one user preferred emotion type and at least one user disliked emotion type. Determining a matching value of each video clip according to the plot information of each video clip in at least one video clip and the preference information of the user, comprising: when determining that the emotion type of one video clip belongs to the emotion type liked by the user according to the plot information of each video clip and the preference information of the user, setting the matching value of the video clip to be 1; when the emotion type of a video clip is determined to belong to the emotion type disliked by the user, the matching value of the video clip is set to 0.
Of course, the above two embodiments are exemplary illustrations, and there are more specific implementations, and the disclosure is not limited thereto.
In a second application scenario, obtaining the play speed according to the matching value includes: when the matching value of the video clip is smaller than a first preset threshold value, acquiring a first preset playing speed, wherein the first preset playing speed is larger than the normal playing speed of the video; and when the matching value of the video clip is greater than or equal to a first preset threshold and less than a second preset threshold, acquiring a second playing speed, wherein the second playing speed is less than the first playing speed and greater than the normal playing speed of the video.
The video clips which are lower in matching with the emotional preference of the user can be played faster, the video clips which are higher in matching with the emotional preference of the user can be played slower, the user can quickly see the video clips which are disliked, the user can normally watch the video clips which are liked, and the user experience is improved.
Of course, the playing speed of the video may also be set to more playing speeds, and the setting is performed in a hierarchical manner according to the difference of the matching values, and the setting manner is similar to that in the two embodiments in step 104, and is not described herein again.
In step 104, the video to be played is played according to the playing speed.
The video playing method provided by the embodiment of the disclosure acquires the preference information of a user; acquiring the playing speed of each video clip according to the plot information and the preference information; and playing the video to be played according to the playing speed. The playing speed of each video clip is obtained according to the plot of each video clip in the video to be played and the emotional preference of the user, so that the playing speed of each video clip in the video to be played meets the requirements of the user, manual adjustment of the user is not needed, and the user experience is improved.
Based on the video playing method provided by the embodiment corresponding to fig. 1, fig. 3 is a flowchart of a video playing method according to an exemplary embodiment, and referring to fig. 3, the video playing method provided by the embodiment includes steps 301 and 307:
in step 301, at least one piece of barrage information of each of at least one video clip is obtained.
In step 302, at least one sentiment score of each video segment is determined according to at least one bullet screen information of each video segment.
For example, taking the score of each video segment containing T emotions as an example, where T is an integer greater than 1, the score can be calculated according to the formula (P) for one video segmentiK) x 100, calculating the score of the ith emotion of the video segment, i being [1, T]Wherein P is an integer ofiThe number of pieces of bullet screen information representing the ith emotion of the video clip, and K represents the number of all the pieces of bullet screen information of the video clip. The sentiment score thus calculated is always 0,100]The proportion of each emotion is reflected, and the calculation result error is not large due to the fact that the standard is different when the final matching value is calculated due to the fact that the number of the bullet screen information of each video clip is different.
In step 303, historical data of the user viewing the video is obtained.
In step 304, a user's preference for at least one emotion is determined based on the historical data.
The user's preference for each emotion can be considered as a weight for that emotion.
It should be noted that there may be no sequence between the steps 301-:
in step 305, the score of at least one emotion of each video segment is weighted according to the user's preference for at least one emotion to obtain a weighted value of at least one emotion of each video segment.
And for one video segment, multiplying the scores of the T emotions by the corresponding preference degrees of the user to the T emotions respectively, namely multiplying the score of the ith emotion by the preference degree of the user to the ith emotion, and calculating to obtain the weighted value of the T emotions of each video segment.
In step 306, a matching value for each video segment is determined based on the weighted value of the at least one emotion for each video segment.
For a video segment, the weighted values of the T emotions are added to obtain the matching value of the video segment.
