Fig. 2 is a flowchart of a video segment acquiring method provided in an embodiment of the present application, where the method is applied to a server. Referring to fig. 2, the method includes:
step 201: and in the live broadcasting process of the live broadcasting room, obtaining gift sending data of the live broadcasting room.
It should be noted that the anchor may have its own live broadcast room, and in the process of live broadcast in its own live broadcast room, viewers watching the live broadcast may give gifts to the anchor.
For example, the anchor may register its user account (hereinafter, referred to as an anchor account) in a terminal used by itself (hereinafter, referred to as an anchor terminal), create a live broadcast room, and then record a live video using the anchor terminal and upload it to a server. The server can send the live video to other terminals displaying the live room, so that the live broadcast of the anchor in the live room can be realized.
The viewer may also log in his user account (hereinafter, referred to as a viewer account) in a terminal used by the viewer (hereinafter, referred to as a viewer terminal), open the live broadcast room in the viewer terminal, and watch the live broadcast of the anchor broadcast in the live broadcast room. In the process of watching the live broadcast, the audience can give a gift to the main broadcast, and specifically, the audience account can be used for giving the gift to the main broadcast account.
In addition, the gift sending data is used for indicating the gift received by the main broadcasting account number of the live broadcasting room and the time of receiving the gift. That is, the gift data may include a gift time and gift information, and the gift information may include a gift identification, a gift number, a gift value, and the like, which is not limited in this embodiment of the present application. The gift identification is used for uniquely identifying the gift, and may be the name, number, etc. of the gift.
For example, in the live broadcasting process of the live broadcasting room, 999 roses are received by the anchor account number of the live broadcasting room at 13:30:05 of 12, month and 4 days in 2019, and the value of each rose is 3, then the server may determine that the gift sending data of the live broadcasting room is as follows: 13:30:05 (presentation time), rose (gift identification), 999 (gift number), and 3 (gift value) on 12, 4 and 2019.
Step 202: and determining a target time period from the live broadcast time period of the live broadcast room according to the gift sending data of the live broadcast room.
Note that the live time period of the live broadcast room is a time period from a time when the live broadcast starts to a time when the live broadcast ends.
In addition, the duration of the target time period is preset duration, and gifts given in the target time period meet preset conditions. The preset time period may be preset, for example, the preset time period may be 20 seconds, 30 seconds, 40 seconds, or the like. The preset condition can also be preset, and the preset condition is used for indicating a gift sending peak. For example, the preset condition may include at least one of the following four items: (1) the total amount of gifts given is the most; (2) the total value of gifts given is the maximum; (3) the total number of gifts given is greater than or equal to a first threshold; (4) the total value of the gifted gift is greater than or equal to the second threshold.
Further, both the first threshold value and the second threshold value may be set in advance. The first threshold value is a threshold value for measuring the number of gifts. When the total number of the gifts is larger than or equal to the first threshold value, the total number of the gifts is more; when the total number of gifts is less than the first threshold value, the total number of gifts is less. The second threshold is a threshold for measuring the value of the gift. When the total value of the gifts is greater than or equal to the second threshold value, the total value of the gifts is larger; when the total value of the gift is less than the second threshold value, it indicates that the total value of the gift is smaller.
It should be noted that the target time period is a time period in which the gifts given within a preset time length in the live broadcast time period of the live broadcast room meet a preset condition, that is, the target time period is a gifting peak time period in the live broadcast process of the live broadcast room. For example, the preset time period is 30 seconds. Assuming that the preset condition is that the total number of gifts to be given is the largest, the target time period is 30 seconds of the largest total number of gifts to be given in the live broadcast time period of the live broadcast room. Assuming that the preset condition is that the total value of gifted gifts is the largest, the target time period is 30 seconds when the total value of gifted gifts in the live broadcast time period of the live broadcast room is the largest. Assuming that the preset condition is that the total number of gifts given is greater than or equal to the first threshold value, and the first threshold value is 100, the target time period is 30 seconds in which the total number of gifts given in the live time period of the live broadcast room is greater than or equal to 100. Assuming that the preset condition is that the total value of gifted gifts is greater than or equal to the second threshold value, and the second threshold value is 1000, the target time period is 30 seconds in which the total value of gifted gifts in the live time period of the live broadcast room is greater than or equal to 1000.
In addition, when step 202 is executed, the server may try to determine the target time period in real time according to the obtained gift-offering data during the live broadcast of the live broadcast room, and then may obtain the target time period when the live broadcast is finished in the live broadcast room. Of course, the server may also determine the target time period according to all the obtained gift-offering data when the live broadcast is finished in the live broadcast room.
Specifically, the operation of determining the target time period from the live broadcast time period of the live broadcast room by the server according to the gift sending data of the live broadcast room may be: the server configures the processing rule of the streaming computation engine to enable gifted gifts in a preset time length to meet a preset condition; and inputting the gift sending data of the live broadcast room into the streaming calculation engine, and outputting the target time period by the streaming calculation engine. Of course, the server may also determine the target time period from the live broadcast time period of the live broadcast room in other ways according to the gift sending data of the live broadcast room, which is not limited in the embodiment of the present application.
It should be noted that the streaming computation engine can analyze large-scale streaming data in real time during the changing motion process. For example, the streaming computing engine may be a storm computing engine, spark computing engine, flink computing engine, and the like, which is not limited in this embodiment of the present application.
In addition, after the processing rule of the streaming computing engine is configured that the gifts given within the preset time length meet the preset condition, the streaming computing engine can process the input gifting data according to the processing rule. Specifically, the streaming calculation engine may determine a live broadcast time period according to the presentation time in the gift data, determine a time period, of which the duration is a preset duration and during which the presented gift meets a preset condition, as a target time period from the live broadcast time period according to the gift information in the gift data, and finally output the target time period.
Furthermore, when the server inputs the gift sending data of the live broadcast room into the stream type calculation engine, the server can input the gift sending data into the stream type calculation engine every time one gift sending data is obtained in the live broadcast process of the live broadcast room, namely, the gift sending data is input into the stream type calculation engine in real time, so that when the live broadcast is finished, the stream type calculation engine can output a target time period; or, the server may input all the obtained gift-sending data into the streaming computing engine when the live broadcast is finished in the live broadcast room, and the streaming computing engine outputs the target time period.
Step 203: and acquiring a target video clip according to the live video and the target time period of the live broadcast room.
Since the target time period is the gift sending peak time in the live broadcast time period of the live broadcast room, the target video clip in the gift sending peak time period can be obtained according to the live broadcast video and the target time period of the live broadcast room, namely the target video clip is a video clip capable of reflecting the gift sending peak time in the live broadcast process of the live broadcast room. That is, in the embodiment of the application, the climax fragment where the gift sending peak is located in the live broadcast can be accurately acquired.
Specifically, the operation of the server obtaining the target video clip according to the live video and the target time slot of the live broadcast room may be: and the server intercepts the video clips in the target time period from the live video of the live broadcast room as target video clips. Or the server firstly intercepts the video clip in the target time period from the live video of the live broadcast room, then acquires the animation of the gift given in the target time period, and then superimposes the animation on the video clip according to the time of the gift given in the target time period to obtain the target video clip.
It should be noted that, in a possible case, the server may directly intercept the target video segment from the live video, so that the target video segment is obtained efficiently. In another possible case, the server may first cut a video clip from the live video, and then superimpose the gift animation on the cut video clip to obtain the target video clip, so that the target video clip includes the live video clip and the gift animation, and the user can directly and clearly see the gift service from the target video clip.
The operation of the server for intercepting the video segments in the target time period from the live video in the live broadcast room is similar to the operation of intercepting the video segments in the certain time period from a certain video in the related art, and details of the operation are not described in the embodiment of the present application. For example, the server may determine a timestamp of each video frame in the live video, acquire all video frames in the live video within a target time period, and then combine all the acquired video frames into a video clip.
When the server obtains the animation of the gift given in the target time period, for each gift given in the target time period, the server can obtain the corresponding animation as the animation of the gift from the corresponding relationship between the gift identifier and the animation according to the gift identifier of the gift. Of course, the server may also obtain the animation of the gift given in the target time period in other manners, which is not limited in the embodiment of the present application.
When the server superimposes the animation onto the video clip according to the time for presenting the gift in the target time period, for each gift presented in the target time period, the server may determine the playing time length of the animation of the gift, then take the presenting time of the gift as a first time, take a time after the presenting time and apart from the presenting time by the playing time length as a second time, take a time period between the first time and the second time as a superimposing time period, and finally superimpose the animation of the gift onto a video frame in the video clip within the superimposing time period. In this way, after the animation of all gifts given in the target time period is superimposed in the video clip, the target video clip can be obtained.
Further, after the server acquires the target video clip, the server can also store the target video clip into the video storage system, so that a subsequent user can view the target video clip at any time. And the server can also store the anchor account of the live broadcast room, the storage address of the target video clip in the video storage system and the video information of the target video clip in a database in a correlated manner.
It should be noted that the video information of the target video segment may include a title, a generation time, and the like of the target video segment. The title of the target video segment may contain information such as the anchor account number, the target time period, the total value of the gifts, or the total number of the gifts. For example, the title of the target time slice may be: anchor a received gifts with a total value of 1000 at 13:30:05 to 13:30:35 on 12, 4, 2019.
In addition, the anchor account of the live broadcast room, the storage address of the target video clip in the video storage system, and the video information of the target video clip are stored in the database in a correlated manner, so that the target video clip of the anchor account and the video information of the target video clip can be conveniently acquired. For example, the storage address and the video information associated with the anchor account may be first queried from the database, and then the target video segment may be obtained from the video storage system according to the storage address, so that the target video segment of the anchor account and the video information of the target video segment may be obtained.
Further, after the server acquires the target video clip, the server can also issue the target video clip as dynamic information of the anchor account of the live broadcast room.
It should be noted that the dynamic information of the anchor account is information displayed on the homepage of the anchor account. When the terminal opens the personal homepage of the anchor account, the dynamic information of the anchor account can be displayed on the personal homepage.
In addition, the dynamic information may include not only the target video clip but also video information of the target video clip. For example, the dynamic information may include a target video segment and a title of the target video segment, so that a user can quickly know the content of the target video segment according to the title.
When the server issues the target video clip as dynamic information of the anchor account of the live broadcast room, the server can display the dynamic information on a personal homepage of the anchor account, and for the account paying attention to the anchor account, the server can send a dynamic reminding message to the terminal logged in with the account, and can display the dynamic information in a dynamic special area displayed in the terminal logged in with the account.
It should be noted that the dynamic reminding message is used to remind the user that the account concerned by the user issues a new dynamic state. The terminal logged in with the account number can display the dynamic reminding message after receiving the dynamic reminding message, and can jump to a dynamic display page to display the dynamic information when receiving a confirmation instruction aiming at the dynamic reminding message.
In addition, the confirmation instruction is used for confirming the dynamic state prompted by displaying the dynamic prompting message, the confirmation instruction can be triggered by a user, and the user can trigger through operations such as click operation, sliding operation, voice operation and gesture operation. The dynamic display page is a page for displaying dynamic information, and may be a personal homepage directly or a page for displaying a piece of dynamic information alone.
The dynamic region is a region for displaying dynamic information of all accounts to which the account is interested. The dynamic information of all the accounts concerned by the account can be displayed in the dynamic special area according to the sequence of the release time.
In the embodiment of the application, the server may obtain the gift sending data of the live broadcast room in the live broadcast process of the live broadcast room, and the gift sending data may include the presentation time and the gift information. And then, the server can determine a target time period from the live broadcast time period of the live broadcast room according to the gift sending data of the live broadcast room, wherein the duration of the target time period is preset duration, and gifts given in the target time period meet preset conditions. And finally, the server acquires a target video clip according to the live broadcast video and the target time period of the live broadcast room. Because the target time period is the gift sending peak time in the live broadcast time period of the live broadcast room, the determined target video clip is a video clip capable of reflecting the gift sending peak time in the live broadcast process of the live broadcast room. That is, in the embodiment of the application, the climax fragment where the gift sending peak is located in the live broadcast can be accurately acquired.
