The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Many users are more concerned about the characters or actors that are interested in them when watching the video, for example, by looking at or reviewing segments of the characters or actors multiple times. In the existing video selection playing mode, if the user wants to select the viewing segment, the playing progress adjustment control is usually adjusted manually, for example, so as to select the position of the video that the user wants to view. Or, the video frame positions of some key plots are displayed to the user, so that the user can directly adjust the playing progress adjusting control to start playing from the video frame of a certain key plot, or the user selects the video frames before and after the key plot as reference points to start playing after watching the video. For example, if the user wants to review a shot of a star after watching the video, the play progress adjustment control may be adjusted segment by segment, or adjusted according to a reference point, so as to focus on the segments of some movie stars and skip a segment when watching the segment of an uninteresting character.
Therefore, the conventional adjustment mode needs a user to manually search in the whole video playing time period, so that the operation is complex, the user can select the starting video frame by adjusting the playing progress adjusting control, the interested segment is likely to be skipped in the adjustment process, and the user experience of the conventional video selection playing mode is poor.
In order to solve the problems in the prior art, the invention provides a video selection playing method, wherein a user side displays roles in a video to a user, the user only needs to select interested roles, and a server extracts key video clips from the video according to the interested roles of the user, so that the user side presents the video clips containing the interested roles of the user to the user. The user side needs simple operation performed by the user, the obtained selective playing effect completely meets the attention of the user to interested roles, the user can selectively watch or selectively review the original video conveniently, and the user experience is improved.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention. In the application scenario shown in fig. 1, a user terminal 1 is a terminal device such as a mobile phone and a video player, and a server 2 is a background server providing a video playing service. The user watches the video data provided by the server 2 through the user terminal 1, and in a play interest mode provided by the user terminal 1, for example, the user can also send a search request for one or more user interested characters in the video to the server 2 through the operation of the user terminal 1. The server 2 responds to the search request to extract video segments of the characters which are interesting to the user from the video data watched by the user, and the video segments are played to the user through the user terminal 1. The video data is transmitted between the user terminal 1 and the server 2, for example, the video stream data can be transmitted in a breakpoint continuous transmission mode.
Referring to fig. 2, which is a schematic flowchart of a video selection playing method according to an embodiment of the present invention, an execution subject of the method shown in fig. 2 may be a user side and a server. Both the client and the server can be software and/or hardware devices. The user terminal may be a mobile terminal or a fixed terminal. The mobile terminal includes, but is not limited to, a mobile device having video playing and user interaction functions, such as a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, a portable device (e.g., a laptop computer, a pocket computer, or a handheld computer), a video player, and the like. The fixed terminal includes but is not limited to a door access, a smart phone, a console and other fixed devices with video playing and user interaction functions. The server may be various servers providing video services, such as a background server providing support for video played by a user terminal. The background server may analyze and perform other processing on the received data such as the video acquisition request and the search request, and feed back a processing result (e.g., video data requested by the user) to the user side. The embodiment of the present invention does not limit the forms of the client and the server.
The method shown in fig. 2 includes steps S101 to S107, which are specifically as follows:
s101, a user side displays a role control corresponding to an original video in a playing interface of the original video.
For example, a user clicks on a video to be viewed (e.g., a tv show, a movie, other user uploading a video file, etc.) on the user side, so that the user side sends a video acquisition request to the server. When receiving a video acquisition request, the server acquires an original video which a user wants to watch according to the video acquisition request. The server also acquires role information in the original video and then determines a plurality of role images, role names and/or actor names according to the role information, wherein the role images comprise role figure images in the original video or actor face images playing roles in the original video. The character image is, for example, a screenshot of a face portion of a character in a video frame image of an original video, or a character snapshot image corresponding to the original video. The image features of the character such as hair style, makeup, etc. should be consistent with the make-up of the character in the original video. The actor face image is, for example, an actor face image obtained by searching in the network based on the actor list information. The pose of the actor's face image may be inconsistent with the pose of the actor in the original video. And the server sends the original video and the role image, the role name and/or the actor name to the user side. So that the user can select the character image, the character name and/or the actor name provided by the user terminal when watching the original video. Fig. 3 is a schematic view of a video playing interface according to an embodiment of the present invention. Fig. 3 illustrates a tablet computer as a user side, and in the video playing interface shown in fig. 3, when a user watches a video, an operable role list is further displayed on one side of the video playing area, so that the user can select a role that the user is interested in, and the video is selectively played.
The method comprises the steps that a client side obtains an original video and a role image, a role name and/or an actor name corresponding to the original video from a server, wherein the role image comprises a role character image in the original video or an actor face image playing a role in the original video. Because the user may need to select the interested role in the watching process, the original video acquired by the user can be understood as the original video stream data which is continuously transmitted at the breakpoint, and the complete original video data is stored in the server. And the user side displays role controls containing the role images, the role names and/or the actor names in a playing interface of the original video, wherein each role control corresponds to one role image, the role name and/or the actor name. Referring to fig. 3, each character image is itself a character control that can be manipulated while the user views the video. It should be understood that the information displayed to the user by each character control may be a character image, a character name, and/or an actor name. For example, as shown in fig. 3, for the role control of the role a, a character image of the role a, the role name "zhang san" of the role a, and the actor name "lie XX" playing the role "zhang san" are displayed. Fig. 3 is intended as an example only, and in other examples, each character control may also display only the character image and character name of the respective character to the user. For example, a character image of character a and a character name "zhang san" of character a are displayed for the character control of character a. The information displayed by the character control to the user may be one of a character image, a character name, and an actor name, and the present invention is not limited thereto.
And S102, the user side generates a search request indicating a target role according to the operation input by the user to the role control.
The user's operation of the character control input may be a click trigger. The search request is, for example, to search for key video snippets that contain any user-selected character. For example, the user clicks a character image of character a and a character image of character C, thereby regarding character a and character C as target characters.
For example, a user side determines at least one target role to be searched according to an operation input by a user on at least one role control, wherein each target role corresponds to one role control; a lookup request indicative of the at least one target role is then generated.
If there is only one target character selected by the user, the search request may be understood as a request to the server to search for a key video clip containing the target character.
If the number of target roles selected by the user is multiple, the process of generating the search request may include, for example: the user side acquires logic information used for indicating the searching relation among the target roles; and then generating a search request indicating the target roles according to the target roles and the logic information.
In some embodiments, the logical information may be preset. For example, after the role a and the role C are taken as target roles, if the preset logic information is logic and information, the generated search request may be a request for acquiring a key video clip simultaneously including the role a and the role C; if the preset value is reached; the logical information is a logic or information, and the generated search request may be a request to obtain a key video clip containing role a or role C.
In other embodiments, the logic information may be input by the user, so that a richer search request more meeting the user requirement may be provided, and the acquired key video clip more meets the user requirement, thereby improving the user experience. For example, the terminal also displays a logic selection control in the playing interface of the original video, see the and button for indicating logic and information and the or button for indicating logic or information shown in fig. 3. When the target roles to be searched are determined, the user side determines a plurality of target roles to be searched and logic information for indicating the searching relation among the plurality of target roles according to the operation input by the user on the logic selection control and the at least one role control, wherein the logic information comprises logic and information and/or logic or information. With continued reference to the example shown in fig. 3, the user terminal may display a logical selection control to the user. If the user sequentially clicks the role image of role a, the logic selection control of logic and information, and the role image of role B, the generated search request may be a request to obtain a key video clip simultaneously containing role a and role C. In addition, the user side may display an input box to the user, and generate the search request according to the logical character string input in the input box by the user.
S103, the server obtains a search request for the original video from the user side, wherein the search request indicates a target role.
Specifically, the user side may generate a search request and then send the search request to the server, or the server may poll and detect that the user side generates a new search request and then actively read the new search request.
And S104, the server acquires the key video frame corresponding to the target role in the original video according to the search request.
The information indicating the target character in the search request may specifically be identification information of the target character (for example, a character name or an actor name), or may be a character image of the target character.
If the search request indicates the target role by using the identification information of the target role, the server may first obtain the target face image of the target role according to the identification information of the target role and a pre-established correspondence between the identification and the face image. The target face image may be the character image mentioned in the above embodiment, or may be one or more images that are additionally provided and can represent the face features of the target character. If the search request indicates the target character as the character image of the target character, the server may directly use the received character image as the target face image, or obtain one or more target face images according to the character image and the face images stored in advance for the respective characters.
In some embodiments, step S104 may specifically be: the server acquires a target face image corresponding to the target role indicated by the search request; then, in the original video, a video frame including the target face image is taken as a key video frame.
After the target face image is acquired, the manner of acquiring the key video frame can be understood as the process of identifying the target face image. Namely, the target face image is taken as a search target, face recognition is carried out in all video frames of the original video, and the video frames which are recognized to contain the target face image are marked as key video frames.
If the search request includes at least one target role. Then, the server may use, as a key video frame, a video frame including target face images of all the target characters in the original video, or use, as a key video frame, a video frame including a target face image of at least one of the target characters.
If the search request comprises a plurality of target roles and logic information used for indicating search relations among the plurality of target roles. Then, the server may take, as a key video frame, a video frame including a target face image of the target character satisfying the logical information in the original video.
S105, the server acquires a key video clip according to the key scene characteristics corresponding to the key video frames, wherein the key video clip is a continuous video frame which comprises at least one key video frame and has the key scene characteristics.
It will be appreciated that due to the continuity of the scenario in the original video, given that in conversational scenarios, both roles of the conversation are typically involved, the roles involved in successive video frames should be switched back and forth between the roles of the conversation. If the user only wants to acquire the video clip of one of the roles and only extracts the video frame of the speech of a single role in the conversation process, the finally obtained video clips are extremely incoherent, and the watching effect of the user is poor. In order to improve the watching effect of the user, the embodiment expands the videos before and after the key video frame according to the scene identification, and expands the video frame range related to the target role, so that the obtained key video clip has a more coherent plot effect, and the watching experience of the user is improved.
Specifically, for example, the server first obtains a key scene feature corresponding to each key video frame. The key scene features are obtained, for example, by performing scene recognition on each key video frame, for example, determining that a scene in the key video frame is a restaurant scene. Then, the server acquires a plurality of adjacent video frames which have the key scene characteristics and are before and/or after the key video frame from a plurality of video frames adjacent to the key video frame. For example, it is determined whether a plurality of consecutive video frames preceding the key video frame are both a restaurant scene, and if so, a video frame preceding and consecutive to the key video frame, which has a restaurant scene characteristic, is included in the neighboring video frames of the key video frame. Similarly, it is determined whether a plurality of consecutive video frames following the key video frame are both a restaurant scene, and if so, a video frame following the key video frame and consecutive to the key video frame, having a restaurant scene characteristic, is included in the neighboring video frames of the key video frame. After determining the adjacent video frames, the server acquires key video clips according to the key video frames which are continuous in the original video and the adjacent video frames corresponding to the key video frames. For example, in a scenario in which the character a collides with another character in a restaurant, a video frame including the character a is used as a key video frame, and video frames before and after the key video frame, which are also scenarios of a restaurant scene, may be determined as adjacent video frames, so that consecutive video frames corresponding to the scenario in which the character a collides with another character in the restaurant are acquired as a key video clip. Through the identification of scene characteristics, the acquired key video clips have higher accuracy, the accuracy and the continuity of video selection playing are further improved, and the user experience is better.
And S106, the server sends the target video information indicating the key video clip to the user side.
In this embodiment, the target video information may be description type information indicating a frame position where the key video clip is located, or may be a video spliced by the key video clip.
In some embodiments, the target video information may include video frame indication information indicating a start frame and an end frame of at least one key video clip corresponding to the target character in the original video. Then, step S106 may specifically be: the server acquires a starting frame and an ending frame of each key video clip in the original video; then according to the starting frame and the ending frame corresponding to the key video clip, acquiring video frame indication information of the key video clip; and sending the video frame indication information to the user side.
