The following describes a method for displaying information in the embodiment of the present application with reference to fig. 2.

In step S202, an acquisition request sent by a client logged in by a target account is received, where the acquisition request is used to request to acquire playing record information of an interactive video played by the target account, the interactive video includes a plurality of video segments, and the plurality of video segments include a played video segment that is selected to skip to be played according to target interaction with the target account.

The interactive video may include a plurality of video segments (e.g., segment 1, …, segment N) that may be jumped between based on the interactive selections at the key video segment in accordance with the jump logic.

The interactive video is represented by a plot structure diagram, and the plot structure diagram comprises: and video nodes corresponding to the video segments and used for indicating a jump indication with a jump relation among the video nodes, wherein the jump indication can be plot lines.

For example, in the interactive video story structure shown in (a) in fig. 3, the interactive video includes 6 video clips (clip 1 to clip 6). At segment 1, a jump to segment 2 or segment 3 may be made according to the user's interactive selection, and thus, there is an episode link between segment 1 and segment 2 and an episode link between segment 1 and segment 3. At segment 2, a jump to segment 4 or segment 5 may be made in accordance with the user's interactive selection, and thus, there is an episodic wiring between segment 2 and segment 4 and an episodic wiring between segment 2 and segment 5. At segment 3, a jump can be made to segment 6, so there is an episodic line between segment 3 and segment 6. At segment 5, a jump can be made to segment 4, so there is an episodic wiring between segment 5 and segment 4. At segment 6, a jump may be made to segment 5, so there is an episodic line between segment 6 and segment 5. In the interactive video story structure shown in (b) of fig. 3, the interactive video includes 8 video clips (clip 1 to clip 8), and the jumping relationship between the respective video clips is similar to that of (a) of fig. 3.

In order to display the playing record information, the plot structure diagram may be processed to obtain a first type of picture corresponding to the video node in the plot structure diagram and a second type of picture corresponding to the skip instruction.

As an optional embodiment, an episode structure diagram corresponding to an interactive video is obtained, wherein the episode structure diagram includes a plurality of target resources; and splitting the plot structure chart into a plurality of resource pictures according to a plurality of target resources.

The method can first obtain a plot structure diagram corresponding to the interactive video, wherein the plot structure diagram comprises a plurality of target resources, and the plurality of target resources comprise: the video node comprises a plurality of video nodes which are in one-to-one correspondence with the video segments and a plurality of jump indications which are used for indicating jump relations among the video nodes.

The manner of obtaining the plot structure diagram may be: and receiving a complete interactive video story structure diagram provided by interactive video editors, and beautifying the story structure diagram after obtaining the story structure diagram so as to improve the visual richness of the story structure diagram and facilitate subsequent chart cutting and splitting.

For example, an interactive video editor provides a complete interactive video story line structure diagram and makes style beautification according to the story. The storyline structure diagram depicts all plot branches and jump logic of the interactive video (as shown in fig. 3). After the user plays all plot branches, the whole playing recording page shows the effect which is completely the same as that of the interactive video plot structure chart.

After obtaining the plot structure diagram, the plot structure diagram may be split into a plurality of resource pictures according to a plurality of target resources, each resource picture may only include one target resource, and the resource pictures and the target resources may be in one-to-one correspondence. The splitting mode can be that the plot structure chart is split by manually positioning each target resource, or the plot structure chart is split by identifying the video node and the jump instruction through the image characteristics. The specific score checking method may be set as required, and this is not specifically limited in this embodiment.

The target resource comprises a video node and a jump instruction, and the obtained multiple resource pictures comprise: a plurality of pictures of a first type and a plurality of pictures of a second type. The size of each first type picture is the same as that of the plot structure chart, each first type picture only comprises one video node, the size of each second type picture is the same as that of the plot structure chart, and each second type picture only comprises one jump indication.

For example, the obtained complete story line structure diagram can be subjected to graph cutting and splitting, and split into two types of pictures, namely a story line and a video clip node, each story line and each video clip node (video node) are independently split into one picture, only one video node (shown as (a) in fig. 4) or one story line (shown as (b) in fig. 4) is arranged in each split picture, the size of each picture is the same as that of the original story line structure diagram, and the background is transparent.

By the embodiment, the obtaining efficiency of the playing record information and the accuracy of the synthesized playing record picture can be improved by obtaining the plot structure chart and splitting the plot structure chart.

As an optional embodiment, in order to improve the accuracy and the matching efficiency of information matching, after obtaining a plurality of resource pictures, an episode description file corresponding to the episode structure picture may be constructed, and the episode description file and the plurality of resource pictures may be saved in a database.

The constructed scenario description file may be in json (JavaScript Object Notation) or xml (eXtensible Markup Language), and various information may be marked in the description file in the form of a list, which may include but is not limited to at least one of the following:

(1) resource ID for uniquely identifying each target resource

The resource id may uniquely identify a resource, which may be a video node or a jump indicator (e.g., a storyline). The resource ID of each target resource has uniqueness, the resource ID of the same target resource may be one (or multiple), and the same resource ID is only used for identifying one target resource.

(2) Resource type for representing type of each target resource

The resource types may be: video node, jump indication (e.g., plot line).

(3) Picture name of each resource picture

Each resource picture may be named. The picture name of the resource picture may be a picture name of a video node or a skip indication picture (e.g., a plot line picture).

(4) Video ID for uniquely identifying each video node

For a video node, the video node can be configured as a unique id of the video. The video ID of the same video node may be one (or multiple), and the same video ID is used to identify only one video node.

The video node may be a video node in the indication plot structure diagram, or may be a picture including the video node. The video ID may also be used to uniquely identify a video clip within the interactive video.

(5) Location information for indicating the location of each target resource in the storyboard

The location information of the video node or the skip indication may be the location of the area where the video node or the skip indication is located in the plot structure chart, and the location information may be represented as the location information of the specific location point of the video node or the skip indication and/or the size of the area where the video node or the skip indication is located.

For example, the story description file may include the location and size of the video nodes or story lines in the overall story structure diagram: as shown in fig. 5, the dotted line area is the size of the entire scenario picture (plot structure diagram), only the video node of the segment 2 in the resource picture of the segment 2 has a map, and other positions are blank, and the position information of the segment 2 is: the position information of the upper left corner of the video node is as follows: (x, y), the size of the video node is: (w, h).

For a storyboard, the location information may be location information for a plurality of specific location points, the plurality of specific location points comprising: starting point, break point, end point (which may be arranged in order).

(6) Relational description Listing

Each entry in the relationship description list contains two first resource IDs or two video IDs corresponding to two video nodes having a jumping relationship, and a second resource ID corresponding to a jumping indication between the two video nodes.

For example, the scenario description file may include a resource relationship description list (listrelationship), only the video node has this content, and let the described video node be videonode a, where each piece of information in the list should include the following content: selecting a resource id of a certain video node to jump to by operating interaction in the video node, for example, VideoNodeB; the scenario link used for linking the videonode a and the videonode b is LineAB. Since one video node may be connected to other video nodes, there are a plurality of pieces of information corresponding to one video node. For example, one example of a description list is as follows:

[{VideoNodeA,VideoNodeB,LineAB},{VideoNodeA,VideoNodeC,LineAC},{VideoNodeA,VideoNodeD,LineAD}]

the sample shows: the video node VideoNodeA is connected with the video node VideoNodeB through an plot connecting line LineAB, is connected with the video node VideoNodeC through a plot connecting line LineAC, and is connected with the video node VideoNodeD through a plot connecting line LineAD.

After obtaining the episode description file, the episode description file and all picture resources may be entered into a resource information database of the background server, and the database is set as DatabaseRes. The total picture resources may include, but are not limited to, at least one of: plot structure, all resource pictures (video plot picture and plot line picture).

By the embodiment, the accuracy and the matching efficiency of information matching can be improved by generating and storing the episode description file and the resource picture in advance.

A client (which may be an application APP, a web page client, a player client, or other forms of clients) logged in through the target account may run on the terminal device. The client can be used for playing interactive videos, and the interactive videos can be stored on the terminal equipment or can be obtained from the server side in real time through a network and stored in a cache of the terminal equipment.

In the process of playing the interactive video through the client, the played video segments of the target account can be recorded in real time so as to quickly determine the played video segments.

Different video clips contained in the interactive video can be identified by different video IDs (identifiers). For example, an interactive video may include 6 video clips, which may be identified by 6 video IDs, respectively: video node a, video node b, video node c, video node d, video node e, video node f, or, video node0, video node1, video node2, video node3, video node4, video node 5.

When the player client is about to start playing the interactive video, the current latest playing record information of the interactive video may be requested from the background, where the latest playing record information at least includes the video ID of the video clip that is newly played by the user, and may be set to idA (latest video clip ID).

In the process of playing the interactive video by the client, the video ID corresponding to the video clip played by the client can be acquired.

As an optional embodiment, in a case that the client plays the first video segment, a first video ID sent by the client may be received, where the first video ID is used to uniquely identify a first video node corresponding to the first video segment, and the played video node includes the first video node, and the first video ID is used to obtain a first video node picture corresponding to the first video node in the first target picture.

The first video segment can be played on the client, for example, the user actively selects to play the first video segment while playing other video segments (the other video segments have no jumping relation with the first video segment), or the user interactively selects to jump to play the first video segment while playing the other video segments (the other video segments have jumping relation with the first video segment). When the first video segment is played, the client may send a first video ID to the background server, where the first video ID is used to uniquely identify the first video segment, or uniquely identify a first video node corresponding to the first video segment. The first video ID is used for acquiring a first video node picture corresponding to the first video node in the first target picture.

The background server can receive the first video ID sent by the client and store the first video ID, and the video ID can be stored in the played video clip list.

After the first video segment is played, according to the episode skipping logic, when the currently played video segment on the client is skipped from the first video segment to the second video segment, the client may send a second video ID to the background server, where the second video ID is used to uniquely identify the second video segment, or uniquely identify a second video node corresponding to the second video segment. The second video ID is used to obtain a second video node picture corresponding to the second video node in the first target picture.

For example, after playing video clip idA, when the user switches to another video clip idB after actively or passively selecting interaction, the client sends video id (idb) of the current video clip to the backend server, and the backend server can store the video id in the playing record database after receiving the video id, and the database is set as database History.

By the embodiment, the efficiency of determining the played video clip can be improved by sending the video identifier of the played video clip in the playing process of the interactive video.

It should be noted that the video segment played by the client may be regarded as a played video segment, where the played video segment refers to a played video segment, and is not necessarily a video segment whose playing is completed (100% playing is completed). The played video clips may be video clips that are jumped to play according to target interaction selection with the target account, but not all played video clips need interaction selection with the target account.

For example, for a first video clip in the interactive video, the first video clip can be played without interactive selection with the target account, and for a video clip with only one branch, the first video clip can be played sequentially without interactive selection with the target account after the previous video clip is played.

In the process of playing the interactive video, when the user selects to view the playing record of the video, the current interactive playing record information can be requested from the background server. The backend server may receive the request.

In step S204, in response to the acquisition request, a first target picture and a second target picture corresponding to the target account are determined.

After receiving the acquisition request, the background server may determine a first target picture corresponding to the target account, where the first target picture includes a played video node corresponding to a played video clip in the episode structure diagram of the interactive video. The first target pictures and the played video nodes can be in one-to-one correspondence, and each first target picture only contains one played video node. In the case that there are multiple played video nodes, there may be multiple first target pictures.

The background server may further determine a second target picture corresponding to the target account, where the second target picture includes a target skip indication between played video nodes in the plot structure diagram of the interactive video. The second target pictures and the target jump indications can be in one-to-one correspondence, and each second target picture only contains one target jump indication. In the case where there are a plurality of target skip indications, there may be a plurality of second target pictures.

As an optional embodiment, determining the first target picture and the second target picture corresponding to the target account includes: determining a played video node corresponding to the played video clip; determining a first target picture corresponding to a played video node; traversing the relation description list by using the played video node, and determining a target entry contained in the relation description list; determining a target jump instruction according to the target entry; and determining a second target picture corresponding to the target jump indication.

In order to determine the first target picture, a played video node corresponding to the played video segment may be first determined, where the played video node may be determined by a video identifier (or a resource identifier) received by the background server during the interactive video playing process.

For example, after receiving the request, the background server may sequentially obtain the video id of each played video clip from the database, and use the video id to look up a video node with the same video id in the database of database, and mark the node as read (viewed). After processing, all viewed video nodes are marked as read. Reading all video nodes marked as read in a database of database baseRes, composing the video nodes into a video NodeList, and creating an empty connection list, i.e. a video NodeLineList.

After the played video node is determined, the played video node may be used to traverse the relationship description list to determine a target entry contained in the relationship description list. Each entry in the relationship description list is used to indicate two video nodes having a jump relationship, and a jump indication between the two video nodes. Each target entry is used for indicating two target video nodes with a jump relation in the played video nodes and target jump indication between the two target video nodes. Through the target entry, a target jump indication may be determined.

It should be noted that the direction of the jump can be represented by the precedence order of the two video nodes in the entry. Meanwhile, the entries of the relationship description list starting from the same video node may be determined to form an entry group representing a plurality of plot branches starting from the video node.

For example, each element in the videonodeldist may be processed in sequence, where the currently processed element is a videonode m, and an element corresponding to the videonode m in the relationship description list (listrelationship) is read and traversed, where the currently traversed element is { videonode m, VideoNodeB, LineAB }, and if both the videonode m and the VideoNodeB in the element exist in the videonodeldist, information of the connection node LineAB is read from the database res and added to the videonodeldist.

After the played video node is determined, a first target picture corresponding to the played video node may be determined. For example, according to the corresponding relation between the video identifier and the resource picture, the resource picture corresponding to the received video identifier is extracted. The extracted resource picture is the first target picture.

After determining the target skip indication, a second target picture corresponding to the target skip indication may be determined. For example, according to the corresponding relationship between the resource identifier and the resource picture, the resource picture corresponding to the resource identifier indicated by the target jump is extracted. The extracted resource picture is also the second target picture.

For example, the resource pictures of all nodes in the video nodelinlistt (video node list) may be taken out, and the resource pictures of all nodes in the video nodelinelist (plot list) may be taken out, so that the first target picture and the second target picture may be obtained. And combining the pictures of each picture as a whole layer to form a new picture Img so as to obtain the playing record picture.

By the embodiment, the first target picture and the second target picture are determined by traversing the relationship description list, so that the process of acquiring the first target picture and the second target picture can be simplified, and the efficiency of acquiring the request response is improved.

In step S206, the first target picture and the second target picture may be combined into a play record picture, and the play record picture is displayed through the client, where the play record information is the play record picture.

After the first target picture and the second target picture are obtained, the first target picture and the second target picture can be synthesized into a play record picture. The synthesis mode can be as follows: and superposing the pixel values at the corresponding positions of all the pixel points. The first target picture comprises played video nodes in the plot structure chart, the second target picture comprises target jump instructions among the played video nodes in the plot structure chart, and the synthesized playing record picture comprises the played video nodes in the plot structure chart and the target jump instructions among the played video nodes, so that the playing record of the interactive video played by the target account can be represented.

After the playing record picture is obtained, the playing record picture can be sent to the client, and the playing record picture is displayed through the client.

The backend server may generate a network link to play the recorded picture (Img picture), calculate the size of the played recorded picture, e.g., set to (ImgW, ImgH), and send the network link and the picture size to the client. After receiving the network link and the picture size of the recorded picture, the client can display the historical record floating layer according to the network link and the picture size of the recorded picture to be played.

Through the embodiment, the recorded picture is played and displayed by sending the network link for playing the recorded picture and the size of the picture, so that the accuracy of displaying the recorded picture can be ensured, and the recorded picture cannot be played due to network transmission errors is avoided.

As an alternative embodiment, sending the network link and the picture size to the client includes: and sending the network link, the picture size and the node information of the played video node to a client, wherein the node information comprises: and the position information is used for indicating the position of the played video node in the plot structure chart.

Besides network link and picture size, the background server can also send the position information of each video node to the client, so that the client can provide an interactive function through the history floating layer.

Optionally, the client may also perform selective playing of the video clip according to a target operation (e.g., a click operation) of the user on the history floating layer. Displaying and playing the recorded pictures on the client through a history record floating layer; detecting a target operation performed on a target position in the history floating layer; responding to the target operation, and determining a third video node of which the position area in the played video node contains the target position according to the position information; and playing a third video clip corresponding to the third video node on the client.

When the play record picture is displayed on the client through the history floating layer, if a target operation (for example, a click operation, a slide operation using the target position as a start point, or the like) performed on a target position in the history floating layer is detected, a third video node whose position area in the played video node includes the target position may be determined according to the position information of the played video node, and a third video clip corresponding to the third video node is played on the client.

For example, when a user clicks on a history floating layer, the videoNodeListT is traversed in turn, and the click position (l)_x，l_y) Comparing the position and size of the element in the videoNodeListT, if a certain node videoNodeP (x)_p,y_p,w_p,h_p) While satisfying the condition x_p+w_p>＝l_x>＝x_p、y_p+h_p>＝l_y>＝y_pThen, the video id in the video node p is read for playing, and the history floating layer can be removed.

Through the embodiment, the selection of the video clip to be played is carried out according to the operation of the user on the history floating layer, so that the control capability of the interactive video can be improved, and the user experience is improved.

It should be noted that, in the process of playing the interactive video, the client may send, to the background server, the video identifier of the video segment before the jump (video identifier before the jump) and the video identifier of the video segment after the jump (video identifier after the jump) or send the video identifier of the video segment after the jump (video identifier after the jump) when the currently played video segment is switched due to the jump.

After receiving the pre-jump video identifier and the post-jump video identifier, or after receiving the pre-jump video identifier and the post-jump video identifier, the background server may put the pre-jump video identifier (the video identifier of the currently played video clip is the pre-jump video identifier) and the post-jump video identifier into the played video clip list, and match a jump indication between the pre-jump video clip (or the pre-jump video node) and the post-jump video clip (or the post-jump video node) from the relationship description list according to the received pre-jump video identifier and the post-jump video identifier, and put the jump indication list into the jump indication list.

And under the condition that the currently played video clip is switched due to non-skip, the client sends the video identifier (switched video identifier) of the switched video clip to the background server.

After receiving the switched video identifier, the background server may put the switched video identifier into the played video segment list.

In this way, the played video segment list stores the played video identifiers (which may be the resource IDs or video IDs of the played video segments or the played video nodes) corresponding to all the played video segments, and the jump indication list stores the target jump indication identifiers (which may be the resource IDs of the target jump indications) of all the target jump indications. The first target picture can be obtained by obtaining the first type of picture corresponding to the played video identifier, and the second target picture can be obtained by obtaining the second type of picture corresponding to the target skipping indication identifier.

The played video segment and the target jump instruction may also be determined in other manners, which are not described in this embodiment one by one, and all other manners capable of determining the played video segment and the target jump instruction may be used for determining the first target picture and the second target picture.
