Below with reference to the accompanying drawings the method obtaining key frame of video and the device of the embodiment of the present application are described.
Fig. 1 is the flow chart of the method obtaining key frame of video of one embodiment of the application, as it is shown in figure 1, the method for this acquisition key frame of video includes:
S101, the video receiving and preserving client upload clicks record, and wherein, video is clicked record and be included video labeling information, video duration and user corresponding video be clicked time point (in order to describe conveniently, be called for short clicking time point below).
Specifically, server clicks record by the video of the multiple client upload of interface, and whether judge that the video received clicks record correct, if correctly, then preserves video and clicks record；If incorrect, then corresponding video clicked record and delete.Wherein, video labeling information can be video ID (Identity, Identity Code).
Specifically, clicking record for each video, whether consistent server, after the video receiving client upload clicks record, can determine whether that video clicks the video labeling information preserved in the video labeling information and date storehouse in record, if inconsistent, then corresponding video clicked record and delete；If consistent, then judge that video is clicked and whether record click time point more than 0, if so, then corresponding video is clicked record and be saved in server, otherwise corresponding video is clicked record deletion.
S102, is divided into video duration at least one time slice in units of the first preset time period, and calculates the user's click volume in each time slice according to clicking time point.
In this embodiment, as in figure 2 it is shown, S102 may include that
S1021, is divided at least one time slice by video duration in units of the first preset time period.
For each video, server preserves substantial amounts of video and clicks record, it is possible in units of the first preset time period such as 1 minute, video duration is divided at least one time slice.
S1022, calculates the user's click volume in each time slice according to clicking time point.
Owing to corresponding video is clicked time point difference by user, therefore, after video duration being divided at least one time slice in units of the first preset time period, record can be clicked by video in traversal server, and the time point that clicks clicked in record according to video calculates the user's click volume in each time slice.
Such as, the video duration of current video is 150 seconds, total click time point is 100, namely user's click volume is 100 times, in units of 1 minute, video duration is carried out division and can obtain three time slices, respectively 1-60 second, 61-120 second and the 121-150 second, it is assumed that calculate and obtain user's click volume of three time slices according to clicking time point and be: the user's click volume in the 1-60 second is 20 times, user's click volume in the 61-120 second is 50 times, user's click volume of 121-150 second is 30 times.
S103, according to user's click volume screening time fragment, and obtains key frame of video from the time slice filtered out.
In this embodiment, as in figure 2 it is shown, S103 may include that
S1031, is ranked up time slice according to user's click volume, and obtains the time slice of predetermined quantity according to ranking results.
Wherein, predetermined quantity is relevant with the number of time slice, and predetermined quantity is less than or equal to the number of time slice.Such as, current video is divided into 10 time slices, after the user's click volume obtaining corresponding time slice, can filter out 5 time slices according to user's click volume from these 10 time slices.
Again such as, current video is divided into 4 time slices, after the user's click volume obtaining corresponding time slice, can filter out 1 or 2 time slices according to user's click volume from these 4 time slices.
Such as, user's click volume that the click volume that three time slices of current video are corresponding is respectively as follows: in the 1-60 second is 20 times, user's click volume in the 61-120 second is 50 times, user's click volume of 121-150 second is 30 times, according to the size of user's click volume, these three time slice can be ranked up, result after sequence is: the user's click volume in the 61-120 second is 50 times, user's click volume of 121-150 second is 30 times, and the user's click volume in the 1-60 second is 20 times.Now, the time slice that user's click volume is maximum, i.e. the 61-120 second of current video can be obtained according to sequence.
S1032, is divided at least one minor time slice section in units of the second preset time period by the time slice filtered out.
Wherein, the second preset time period in this embodiment is less than the first preset time period, and the second Preset Time can be such as 1 second.
In order to accurately obtain key frame of video, after the time slice obtaining predetermined quantity, for each time slice filtered out, the time slice filtered out is divided at least one minor time slice section in units of the second preset time period such as 1 second.
S1033, calculates the user's click volume in each minor time slice section according to clicking time point.
S1034, it is thus achieved that the minor time slice section that user's click volume is maximum, and according to the minor time slice section key frame of video corresponding with video labeling information acquisition.
Specifically, after the user's click volume obtained in each minor time slice section, and obtain, according to user's click volume, the minor time slice section that user's click volume is maximum, and according to the minor time slice section key frame of video corresponding with video labeling information acquisition.
In this embodiment, after obtaining key frame of video according to the time slice filtered out, it is also possible to preserve the key frame of video of correspondence in data base according to video labeling information, to facilitate editorial staff to edit key frame of video.Such as, editorial staff can add story of a play or opera summary or advertisement etc. at key frame of video place.
nullSuch as，The video duration of current video is 150 seconds，Assuming that the user's click volume in the 1-60 second of current video is 20 times、User's click volume in the 61-120 second is 50 times、User's click volume in the 121-150 second is 30 times，According to the 61-120 second that time slice is current video that user's click volume filters out，The time point corresponding at most in order to user's click volume can be obtained more accurately，This time point is the time point corresponding to the key frame of video of current video，With 1 second, the time slice of current video can be divided，Namely in units of 1 second, the 61-120 second of current video is divided into multiple minor time slice section，And obtain user's click volume that each minor time slice section is corresponding，If the user's click volume obtained in minor time slice section the 80th second is maximum according to analyzing，Now，The 80th second corresponding frame of video of current video can be obtained from server according to video labeling information，This frame of video is the key frame of video that current video is corresponding.Thus, the key frame of video of current video is obtained in conjunction with the service condition of user, facilitate editorial staff in this key frame of video, add the story of a play or opera summary of correspondence, and then facilitate user when watching current video, navigate to the time point that key frame of video is corresponding, to understand the excellent story of a play or opera summary at key frame of video place in advance, improve user and watch the Consumer's Experience of video.
The method obtaining key frame of video of the embodiment of the present application, video labeling information, video duration and the user video clicking time point to corresponding video that comprises receiving and preserving client upload clicks record, and in units of the first preset time period, video duration is divided at least one time slice, and calculate the user's click volume in each time slice according to clicking time point；And according to user's click volume screening time fragment, and obtain key frame of video from the time slice filtered out, this embodiment can accurately obtain, by analyzing the video click record of client upload, the key frame of video that user is interested, facilitate editorial staff to edit according to this key frame of video, and then the suggesting effect of key frame of video can be improved, improve user and watch the user experience of video.
