Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The video retrieval method provided by the embodiment of the application is applied to the video retrieval system shown in fig. 1, and the video retrieval system comprises a user terminal and a server.
The user terminal is used for generating target video picture information to be retrieved after detecting video retrieval operation of a user and sending the target video picture information to the server; then, the retrieval result obtained from the server is displayed, and the video selected by the user according to the retrieval result is played. For example, the user terminal may be an electronic device such as a mobile phone, a tablet computer, and a personal computer.
In the embodiment of the present application, the video picture information is information representing video content, and the video picture information includes at least one of voice, subtitles, and pictures. The voice can be an original sound audio clip containing a human conversation in the video, and can also be voice sent by a user; the caption may be a speech of a character in the video and the picture may be a video picture. Besides voice, subtitle and video pictures, the video picture information may also be other forms of video content, for example, the video picture information may be bullet screen information displayed when playing video, names of buildings and people in the video picture, and the like.
The server is used for receiving target video picture information to be retrieved sent by the user terminal, retrieving a target video containing the target video picture information, acquiring video playing information of the target video picture information in the target video, and generating a retrieval result containing a video identifier of the target video and the video playing information; then, the search result is sent to the user terminal, so that the user terminal displays the search result. The server may be an electronic device with video retrieval functionality, for example, the server may be a background server of a video website.
Based on the video retrieval system shown in fig. 1, an embodiment of the present application provides a video retrieval method, which is applied to the server shown in fig. 1, and as shown in fig. 2, the method includes:
step 201, receiving target video picture information to be retrieved sent by a user terminal.
In implementation, when a user wants to search a certain video and only memorizes the lines in the video or stores the video pictures of the video, the user can input the lines and/or the video pictures, and then the user terminal can generate target video picture information to be retrieved according to the lines and/or the video pictures input by the user. Thereafter, the user terminal may transmit the target video picture information to the server. The specific processing procedure of the user terminal generating the target video picture information to be retrieved will be described in detail later.
The server may then receive the target video picture information to be retrieved.
For example, the target video picture information may be a subtitle "tomorrow will be a nice day" or the target video picture information may be a video picture as shown in fig. 3.
And 202, matching the target video picture information with the video picture information of each video stored in advance, and determining the target video containing the target video picture information.
In an implementation, the server may determine a form of video picture information included in the target video picture information, where the form of the video picture information may be one of voice, subtitle, and picture.
Then, the server can determine the video picture information of the corresponding form of each video according to the form that the target video picture information contains the video picture information, and then search the matched video picture information matched with the target video picture information in the video picture information of the corresponding form of each video. Then, the server may take the belonging video matching the video picture information as a target video containing the target video picture information.
For example, the server may determine that the video picture information included in the target video picture information "will be a good day in the tomorrow" is in the form of subtitles, and then, the server may determine the subtitles of each video, and then search for a matching subtitle in the subtitles of each video that matches the target video picture information "will be a good day in the tomorrow". Then, the server can use the video "dinning world beauty" to which the subtitle is matched as the target video containing the target video picture information.
In the embodiment of the application, in order to facilitate the server to quickly determine the target video, the user terminal may further send attribute information of the video to be retrieved while sending the picture information of the target video, where the attribute information includes, for example, a video category and a video duration range. Therefore, the server can screen each video according to the attribute information, and then search the target video containing the target video picture information in the screened videos.
Step 203, acquiring video playing information of the target video picture information in the target video.
The video playing information comprises a playing time stamp and/or a preview video frame corresponding to the playing time stamp of the target video picture information. The server may store a correspondence between the video picture information and the play time stamp in advance.
In implementation, the server may determine, according to a correspondence between the pre-stored video picture information and the playing timestamp, the playing timestamp corresponding to the matching video picture information as the playing timestamp corresponding to the target video picture information in the target video.
For convenience of description, a playing time stamp corresponding to the target video picture information in the target video may be referred to as a matching playing time stamp, and after the matching playing time stamp is determined, the server may determine that the corresponding playing time stamp is a video frame of the matching playing time stamp, so as to obtain the preview video frame.
In this embodiment of the application, the preview video frame may be one video frame corresponding to the matching playing timestamp, or may be a plurality of video frames corresponding to the matching playing timestamp. For example, the matching playing time stamp is 15s, and the preview video frame may be a video frame with a playing time stamp of 15s, or may be a video frame with playing time stamps of 14s, 15s, and 16 s.
And 204, generating a retrieval result containing the video identifier of the target video and the video playing information, and sending the retrieval result to the user terminal so that the user terminal can display the retrieval result.
In implementation, the server may obtain the video identifier of the target video, generate a search result including the video identifier of the target video and the video playing information, and then send the search result to the user terminal, so that the user terminal displays the search result.
In the embodiment of the application, the server stores the video picture information of each video in advance, and after receiving the target video picture information, the server can match the target video picture information with the video picture information of each video to determine the target video containing the target video picture information. Then, the server can acquire video playing information of the target video picture information in the target video. Then, the server can generate a retrieval result containing the video identifier and the video playing information of the target video, and send the retrieval result to the user terminal, so that the user terminal can display the retrieval result.
On the other hand, compared with the related art that a user can only drag the play progress bar to search the video content to be watched, in the technical scheme provided by the embodiment of the application, the server can acquire the video playing information of the video picture information in the target video and generate a retrieval result containing the video identifier of the target video and the video playing information. Therefore, the user terminal can conveniently play the target video according to the video playing information, and the user experience can be improved.
Optionally, the server may store the video picture information of each video by storing a corresponding relationship between the video picture information and the video identifier, and for the video picture information of different forms, the server may store a corresponding relationship between the video picture information of the corresponding form and the video identifier in advance, so as to search the video picture information matched with the target video picture information based on the corresponding relationship.
For example, for video picture information in text form, the server may store a correspondence between subtitles and video identifiers to indicate subtitles appearing in a certain video. For the video picture information in the form of pictures, the server may store a corresponding relationship between a video frame and a video identifier to indicate a video frame included in a certain video. For the video picture information in the form of voice, the server may store the corresponding relationship between the audio clip and the video identifier to represent the sound appearing in a certain video.
For different forms of video picture information, the server searches for video picture information matched with target video picture information in the corresponding relationship between the video picture information and the video in different ways, and the embodiment of the application provides four implementation ways:
in a first mode, for video picture information in a picture form, the server may sequentially obtain video frames in a corresponding relationship between the video frames and the video identifiers, and calculate image similarity between a picture included in the target video picture information and the video frames. When the image similarity is greater than the preset image similarity threshold, the server may regard the video frame as a video frame matched with the target video picture information.
And secondly, aiming at the video picture information in the text form, the server can sequentially acquire the subtitles in the corresponding relation between the subtitles and the video identifications, and calculate the similarity between the texts contained in the target video picture information and the texts contained in the subtitles. When the similarity is greater than the preset similarity threshold, the server may regard the subtitle as a subtitle matched with the target video picture information.
In a feasible implementation manner, the video content information in the form of characters may be bullet screen information in a video, and the server may sequentially obtain the bullet screen information in the correspondence between the bullet screen information and the video identifier, and calculate the similarity between the characters contained in the target video content information and the characters contained in the bullet screen information. When the similarity is greater than the preset similarity threshold, the server may use the bullet screen information as bullet screen information matched with the target video content information. Then, the server may use the matched playing time stamp of the bullet screen information as the corresponding playing time stamp of the target video content information in the target video.
And thirdly, aiming at the video picture information in the voice form, the server can sequentially acquire the audio clips in the corresponding relation between the audio clips and the video identifications, and calculate the similarity between the voice contained in the target video picture information and the audio clips. When the similarity is greater than the preset similarity threshold, the server may regard the audio clip as an audio clip matching the target video picture information.
And in the fourth mode, aiming at the video picture information in the voice form, the server can convert the voice into characters, and then, in the second mode, the subtitle matched with the target video picture information is searched.
In the embodiment of the application, aiming at different forms of target video picture information, the server can search the video picture information matched with the target video picture information in various ways. Therefore, even when the user searches for video content such as a speech or a video screen, the server can search for a target video including the speech or the video screen, and the video search effect can be improved.
Compared with the prior art that a user can only retrieve videos in a video title retrieval mode, the technical scheme provided by the embodiment of the application can realize video content retrieval based on various forms of voice, subtitles, pictures and the like by using the association of the videos and the video picture information when the server retrieves the videos, so that the user can retrieve the videos in the video content retrieval mode, and the user experience can be improved while the video retrieval effect is improved.
Based on the video retrieval system shown in fig. 1, an embodiment of the present application further provides a video retrieval method, which is applied to the user terminal shown in fig. 1, and as shown in fig. 4, the method includes:
step 401, obtaining target video picture information to be retrieved input by a user, and sending the target video picture information to be retrieved to a server.
In practice, when a user wants to search a certain video and only remember the speech in the video or the video content information such as the video picture storing the video and the audio clip of the original sound of the character dialogue in the video, the user can input at least one of the speech, the video picture and the audio clip of the original sound. After detecting the input operation of the user, the user terminal may acquire the video content information input by the user.
The method for acquiring the video content information input by the user terminal can be various, and in a feasible implementation mode, the user terminal can acquire characters input by the user in an information search box of a video website; in another possible implementation manner, when the user adopts a voice input manner, the user terminal may capture voice uttered by the user, or the user terminal may receive an acoustic audio clip uploaded by the user and containing a character conversation in a video. In yet another possible implementation, the user terminal may receive a picture uploaded by the user.
Then, the user terminal can generate target video picture information to be retrieved according to the video content information input by the user. For example, the user terminal may use the acquired text and the received picture as the target video content information to be retrieved. If the voice received by the user terminal is the voice sent by the user, the user terminal can convert the voice into characters, and the characters obtained through conversion are used as target video content information to be retrieved. If the voice received by the user terminal is an acoustic audio clip, the user terminal can directly take the acoustic audio clip as the target video content information to be retrieved, and the user terminal can also convert the acoustic audio clip into characters and take the characters obtained through conversion as the target video content information to be retrieved.
And then, the user terminal can send the target video picture information to be retrieved to the server so that the server matches the target video picture information with the video picture information of each video stored in advance, determines the target video containing the target video picture information, acquires the video playing information of the target video picture information in the target video, generates a retrieval result containing the video identifier and the video playing information of the target video, and sends the retrieval result to the user terminal. The specific processing procedure of the server for generating the search result based on the target video picture information may refer to the related description of step 201 to step 204, which is not described herein again.
Step 402, receiving the search result sent by the server.
Step 403, displaying the search result.
In implementation, the retrieval result includes the video identifier of the target video and video playing information, and the video playing information includes a playing time stamp and/or a preview video frame corresponding to the playing time stamp of the target video frame information.
The user terminal can display the video identification of the target video in a preset display interface. The preset display interface may be a search result display interface of a video website, and the video identifier may be, for example, a video title or a video cover page. Fig. 5a is a schematic diagram of a display interface displaying a video identifier of a target video according to an embodiment of the present application.
While displaying the video identifier, the user terminal may also display a playing time stamp of the target video picture information in the target video and/or a preview video frame corresponding to the playing time stamp of the target video picture information, and a detailed description will be given later on a specific processing procedure.
In the embodiment of the application, the user terminal can acquire target video picture information to be retrieved input by a user, and send the target video picture information to be retrieved to the server, so that the server matches the target video picture information with video picture information of each video stored in advance, determines a target video containing the target video picture information, acquires video playing information of the target video picture information in the target video, generates a retrieval result containing a video identifier of the target video and the video playing information, and sends the retrieval result to the user terminal. In this way, the user terminal can display the retrieval result containing the video identification and the video playing information of the target video. When the user searches for video content such as a speech or a video picture, the user terminal can display a search result of a target video including the speech or the video picture and video playback information, and therefore the video search effect can be improved.
Optionally, under the condition that the video playing information includes the playing time stamp of the target video picture information, the user terminal may display the playing time stamp of the target video picture information while displaying the video identifier of the target video, as shown in fig. 5b, a schematic diagram of a display interface displaying the playing time stamp of the target video picture information provided in the embodiment of the present application is provided, where a video title of each target video and the playing time stamp of the target video picture information in the target video are displayed.
In the case that the video playing information includes a preview video frame corresponding to the playing time stamp of the target video frame information, if the preview video frame includes one video frame, the user terminal may use the video frame as a video cover of the target video, and display the video cover of the target video while displaying the video identifier of the target video in the display interface.
If the preview video frame comprises a plurality of video frames, the user terminal can select a certain video frame in the plurality of video frames as a video cover of the target video, and the video cover of the target video is displayed while the video identifier of the target video is displayed in the display interface; alternatively, the user terminal may cycle through multiple video frames.
In the embodiment of the application, under the condition that the retrieval result received by the user terminal includes video playing information of the target video picture information in the target video, the user terminal can display the video playing information on a preset display interface, so that a user can conveniently know more related information of the target video. Therefore, when the user terminal displays a plurality of target videos, the user can preview the target videos in a mode of watching preview video frames, or the user can filter the target videos by combining the playing time stamps with the playing time of the lines or video pictures in the memory, so that the target videos to be watched are quickly positioned, and the video retrieval efficiency is further improved.
Optionally, in a case that the video playing information includes a preview video frame corresponding to the playing timestamp of the target video picture information, the user terminal may directly display the preview video frame, or the user terminal may display the preview video frame after receiving a video preview request from the user. As shown in fig. 6, the specific process of the user terminal displaying the preview video frame based on the video preview request includes:
step 601, displaying the video identification of the target video.
Step 602, obtaining a video identifier of a target video to be previewed carried by the video preview request.
In implementation, when the user wants to further know the video content included in the target video, the user may perform a video preview operation to enable the user terminal to obtain a video preview request. A video preview operation, such as right-clicking on a video identification of the target video, hovers a cursor in a display area representing the target video in the display interface.
After the video preview request is obtained, the user terminal can obtain the video identifier of the target video to be previewed, which is carried by the video preview request.
Step 603, in the search result, determining a target preview video frame corresponding to the video identifier.
In implementation, since the video identifier of the target video and the preview video frame corresponding to the playing time stamp of the target video are stored in the retrieval result of the target video picture information, the user terminal may use the preview video frame corresponding to the video identifier of the target video to be previewed as the target preview video frame in the retrieval result of the video picture information.
Step 604, displaying the target preview video frame.
In implementations, the user terminal may display the target preview video frame in a display area of the target video.
In the embodiment of the application, the user terminal can acquire the video identifier of the target video to be previewed carried by the video preview request, determine the target preview video frame corresponding to the video identifier in the retrieval result, and then display the target preview video frame. Because the user terminal can respond to the video preview request and display the target preview video frame, under the condition that the user terminal displays a plurality of target videos, the user can know the video content contained in the target videos by watching the target preview video frame, quickly locate the videos to be watched and further improve the video retrieval efficiency.
Optionally, after the user determines the target video that the user wants to watch based on the retrieval result displayed by the user terminal, the user terminal may provide a skip playing function of the target video for the user, as shown in fig. 7, and the specific processing procedure includes:
step 701, acquiring a video identifier of a target video to be played, which is carried by the video playing request.
In implementation, when a user wants to play a certain target video, the user may perform a video display operation to enable the user terminal to obtain a video playing request. The video display operation is, for example, double-clicking a video flag of the target video with a left key, or selecting "on" in the displayed option menu bar in a state where the display area of the target video is indicated in the right key selection.
After the video playing request is obtained, the user terminal can obtain the video identifier of the target video to be played, which is carried by the video playing request.
Step 702, determining a target playing time stamp corresponding to the video identifier.
In implementation, the manner in which the user terminal determines the target play time stamp corresponding to the video identifier may be various. In a feasible implementation manner, when the retrieval result further includes video playing information of the target video picture information in the target video, and the video playing information includes a playing time stamp, since the video identifier of the target video and the playing time stamp of the target video picture information are correspondingly stored in the retrieval result of the target video picture information, the user terminal may use the playing time stamp corresponding to the video identifier of the target video to be played as the target playing time stamp in the retrieval result of the target video picture information.
In the embodiment of the application, when the retrieval result further includes video playing information of the target video picture information in the target video, and the video playing information includes the playing time stamp, the user terminal can acquire the target playing time stamp from the received retrieval result, so that the target playing time stamp can be quickly determined.
In another possible implementation manner, in a case that the retrieval result of the target video picture information does not contain the playing time stamp, the user terminal may obtain the playing time stamp of the target video picture information in the target video from the server.
And step 703, starting to play the target video to be played from the target playing time stamp.
As shown in fig. 5c, for a schematic view of a playing page provided in this embodiment of the application, in a possible implementation manner, the user terminal may further prompt a prompt such as "according to a search result, you have automatically jumped to the on-demand playing".
In the embodiment of the application, the user terminal can acquire the video identifier of the target video carried by the video playing request, then determine the target playing timestamp corresponding to the video identifier, and start playing the target video from the target playing timestamp. The user terminal can determine the target playing time stamp of the video content which the user wants to watch in the target video and starts to play the video from the target playing time stamp, so that the accurate positioning of the target video picture information and the jumping playing of the target video can be realized. By adopting the technical scheme provided by the embodiment of the application, the problem that a user can only search the video content to be watched by adjusting the playing progress bar in the related technology can be avoided, so that the user experience can be improved, and further, the user retention rate can be improved.
