Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The method and the device aim to solve the problem that in the related technology, a terminal cannot timely acquire a highlight video segment required to be clipped by a user due to the fact that a server transcodes the video segment required to be clipped by the user in real time and needs a certain processing time, namely, the user needs to wait for a period of time to see the highlight video segment required to be clipped after clicking on a live video clip.

The embodiment of the disclosure provides a video clipping method and device, a video distribution server and a terminal.

For clarity of description of the solution, in the first aspect, a video clip system provided by the embodiments of the present disclosure is first briefly introduced in conjunction with an application scenario.

As shown in fig. 1, a video clip system provided by an embodiment of the present disclosure includes: a terminal 110, a source station server 120, and a video distribution service 130. The video distribution server 130 may also be referred to as a CDN (Content delivery network) node server.

Specifically, the interaction process among the terminal 110, the source station server 120, and the video distribution server 130 is as follows.

In step S11, the terminal 110 transmits a request to the source station server 120 to acquire live video from the video distribution server 130.

When a user wants to watch a live video by using the terminal 110, the terminal 110 needs to pull the live video to the video distribution server, at this time, the terminal 110 may send a request for the video distribution server 130 to obtain the live video to the source station server 120, so that in a subsequent step, the source station server 120 may feed back address information of the video distribution server 130 corresponding to the live video to the terminal 110.

In step S12, the terminal 110 receives the address information of the video distribution server 130 corresponding to the live video transmitted by the source station server 120.

Specifically, since the live video and the video distribution server 130 have a corresponding relationship, the source station server 120 may determine the address information of the video distribution server 130 corresponding to the live video after receiving the request for acquiring the live video sent by the terminal 110.

In step S13, a playback request for live video is transmitted to the video distribution server 130 based on the address information of the video distribution server 130.

Specifically, after obtaining the address information of the video distribution server 130 of the live video, the terminal 110 may send a play request for the live video to the video distribution server 130 according to the address information of the video distribution server 130.

In step S14, the video distribution server 130 transmits the live data stream of the live video to the terminal 110.

The video distribution server 130 may transmit a live video stream of the live video to the terminal 110 after receiving a play request of the terminal 110 for the live video.

In step S15, the terminal 110, upon receiving the clip operation, transmits a clip request for live video to the video distribution server 130.

Wherein the clipping request includes a live time at which the terminal 110 live the video upon receiving the clipping operation.

Specifically, in the process that the user watches the live video through the terminal 110, if the user watches the highlight video segment in which the user is interested, the user needs to clip the highlight video segment, at this time, the user performs a clipping operation on the live video, and thus the terminal 110 receives the clipping operation of the user on the live video.

In practical applications, in the process of playing the live video by the terminal 110, whether the user's clipping operation on the live video is received or not can be monitored in real time. When receiving a clipping operation of a live video by a user, the terminal 110 may send a clipping request to the video distribution server 130, where the clipping request carries a live time of the live video when the terminal receives the clipping operation.

In step S16, the video distribution server 130 determines, from the clip request, video address information of a target clip video including at least one video segment within a preset time period before the live time.

The video address information comprises sub-video address information corresponding to at least one video segment, and the target clip video is a segment of a live video stream with preset duration cached by a video distribution server in the live broadcasting process.

Specifically, the duration of the highlight video segment that the user wants to clip is not too long in general, and therefore, the video distribution server 130 may determine, after receiving the clip request for the live video sent by the terminal 110, the video address information of the target clip video of the at least one video segment included in the preset time period before the live time, where the video address information includes sub-video address information corresponding to the at least one video segment. In this way, in the subsequent steps, the target clip video acquired by the terminal 110 according to the video address information can meet the clipping requirement of the user, that is, the user can view the highlight video segment that the user wants to clip.

Moreover, since the duration of the highlight video segment that the user wants to clip is usually not too long, the preset time period may be 30 seconds, 60 seconds, or 90 seconds, and the like, and of course, the preset time period may be determined according to actual situations, and the preset time period is not specifically limited in the embodiment of the present disclosure.

It can be understood that, in the live broadcasting process, since the live video stream with the preset duration is cached in the video distribution server 130, the preset duration may be 1 minute, 2 two minutes, 3 minutes, and the like, and the size of the preset duration is not specifically limited in the embodiment of the present disclosure. And the target clip video is at least one video segment included in a preset time period before the live time, and thus, the target clip video is a segment of the live video stream of a preset duration cached by the video distribution server 130.

In step S17, the video distribution server 130 transmits the video address information to the terminal 110.

Specifically, after the video distribution server 130 determines the video address information, in order that the terminal 110 can acquire the target clip video from the video address information in the subsequent step, the video distribution server 130 may transmit the video address information to the terminal 110.

In step S18, the terminal 110 acquires the target clip video from the video address information.

Specifically, after the terminal 110 acquires the video address information of the target clip video, the target clip video may be acquired according to the video address information. Moreover, the target clip video is a clip video of at least one video segment included in a preset time period before the live broadcast moment, so that the target clip video acquired by the terminal can meet the clipping requirement of the user, namely the target clip video includes a wonderful video segment which the user wants to clip.

After the video clipping system provided by the embodiments of the present disclosure is introduced, in a second aspect, a video clipping method applied to a video distribution server provided by the embodiments of the present disclosure will be described in detail.

As shown in fig. 2, a video clipping method applied to a server according to an embodiment of the present disclosure may include the following steps:

in step S21, a clip request for live video sent by the terminal is received.

Wherein the clipping request comprises the live broadcast time of the live broadcast video when the terminal receives the clipping operation.

Specifically, in the process that a user watches live video through a terminal, if a highlight video segment which the user is interested in is watched, the user needs to clip the highlight video segment, at the moment, the user can perform clipping operation on the live video, and therefore the terminal receives the clipping operation of the user on the live video.

In practical application, in the process of playing the live video by the terminal, whether the editing operation of the live video by the user is received or not can be monitored in real time. When receiving a clipping operation of a user on a live video, the terminal can send a clipping request to the video distribution server, wherein the clipping request carries a live video live time when the terminal receives the clipping operation.

In step S22, video address information of a target clip video including at least one video segment within a preset time period before the live time is determined according to the clip request.

Specifically, the duration of the highlight video segment that the user wants to clip is usually not too long, and therefore, after receiving a clip request for the live video sent by the terminal, the video distribution server may determine video address information of a target clip video of at least one video segment included in a preset time period before the live time, where the video address information includes sub-video address information corresponding to the at least one video segment. Therefore, in the subsequent steps, the target clip video acquired by the terminal according to the video address information can meet the clipping requirement of the user, namely, the user can watch the wonderful video segment which the user wants to clip.

It can be understood that, in the live broadcasting process, since the live video stream with the preset duration is cached in the video distribution server, the preset duration may be 1 minute, 2 two minutes, 3 minutes, and the like, and the size of the preset duration is not specifically limited in the embodiment of the present disclosure. And the target clip video is at least one video segment included in a preset time period before the live time, and thus, the target clip video is a segment of the live video stream of a preset duration cached by the video distribution server 130.

In step S23, the video address information is transmitted to the terminal so that the terminal acquires the target clip video from the video address information.

Specifically, after the terminal acquires the video address information of the target clip video, the target clip video can be acquired according to the video address information. Moreover, the target clip video is a clip video of at least one video segment included in a preset time period before the live broadcast moment, so that the target clip video acquired by the terminal can meet the clipping requirement of the user, namely the target clip video includes a wonderful video segment which the user wants to clip.

On the basis of the example shown in fig. 2, in an implementation, in step S22, determining, according to the clip request, video address information of a target clip video including at least one video segment in a preset time period before the live time, as shown in fig. 3, the following three steps may be included, which are step S221 to step S223:

in step S221, at least one video segment within a preset time period before the live time is determined according to the clip request.

Specifically, the clipping request includes a live time of a live video when the terminal receives the clipping operation. Since the duration of the highlight video segment that the user wants to clip is usually not too long, in order to meet the video clip requirement of the user, the server may determine at least one video segment included in a preset time period before the live time after receiving a clip request for the live video sent by the terminal.

It is to be understood that, since the duration of the highlight video segment that the user wants to clip is usually not too long, the length of the preset time period is not too long, the preset time period may be 30 seconds, 60 seconds, or 90 seconds, etc., and the length of the preset time period may be determined according to practical situations, and the length of the preset time period is not particularly limited in the embodiment of the present disclosure.

In step S222, sub-video address information corresponding to each of at least one video clip is acquired.

Specifically, each video clip corresponds to one piece of sub-video address information, so that after the server determines at least one video clip, the server can acquire the sub-video address information corresponding to each video clip in the at least one video clip according to the corresponding relationship between the video clip and the sub-video address information.

In step S223, a target file in a preset format is generated.

Wherein the target file includes sub-video address information.

Specifically, after the server acquires the sub-video address information corresponding to each video clip of the at least one video clip, the server may generate the acquired sub-video address information into a target file in a preset format, so that in the subsequent steps, when the server transmits the video address information to the terminal, the server may transmit the target file in the preset format to the terminal.

It should be noted that each video clip included in the preset time period before the live broadcast time has a sequential playing sequence. For example, in a preset time period before the live broadcast time, 3 video clips are included, and the playing sequence is video clip 1, video clip 2 and video clip 3 in sequence. Video segment 1 corresponds to the first sub-video address information, video segment 2 corresponds to the second sub-video address information, and video segment 3 corresponds to the third sub-video address information, so that the generated target file may include a sub-video address information sequence composed of the first sub-video address information, the second sub-video address information, and the third sub-video address information. In this way, in the subsequent step, after acquiring the target file, the server may acquire the target clip video according to the sequence of the sub-video address information included in the target file.

Therefore, according to the technical scheme provided by the embodiment, after receiving the clipping request, the server can determine at least one video segment in a preset time period before the live broadcast time according to the clipping request; acquiring sub-video address information corresponding to each video clip in at least one video clip; and generating a target file with a preset format, wherein the target file comprises sub-video address information corresponding to each video clip in at least one video clip. Therefore, in the subsequent steps, after the terminal receives the target file with the preset format, each video clip in at least one video clip can be obtained according to the sub-video address information included in the target file.

On the basis of the embodiment shown in fig. 3, in an implementation manner, generating the target file in the preset format may include the following steps:

and generating the target file in the m3u8 format.

Specifically, since the common players all support the m3u8 format, the server may generate a target file in the m3u8 format, where the target file includes sub video address information corresponding to at least one video clip included in a preset time period before the live broadcast time.

Accordingly, the step S23 of sending the video address information to the terminal may include the steps of:

and transmitting the target file in the m3u8 format to the terminal.

Specifically, since the player of the terminal generally supports the m3u8 format, after acquiring the target file in the m3u8 format, the terminal may acquire each of the at least one video segment according to the sub video address information included in the target file in the m3u8 format.

Also, as an optional implementation manner of the embodiment of the present disclosure, after the target file in the m3u8 format is sent to the terminal, the video clipping method may further include:

receiving a video request sent by a terminal according to the address information of each sub video in the target file in the m3u8 format;

Specifically, after receiving the object file in the m3u8 format, the terminal may obtain the video clips corresponding to the sub video address information according to the sub video address information included in the object file in the m3u8 format.

Since the target file in the m3u8 format includes the sub-video address information corresponding to at least one video clip, after the terminal acquires one sub-video clip according to one sub-video address information, the terminal can simultaneously acquire the next video clip from the server in the process of previewing the video clip until all the video clips included in the preset time period are acquired, so that the user can watch the highlight video clip which the user wants to clip in time.

In a third aspect, a video clipping method applied to a terminal according to an embodiment of the present disclosure will be described in detail.

As shown in fig. 4, a video clipping method applied to a terminal according to an embodiment of the present disclosure may include the following steps:

in step S41, in the course of playing the live video by the terminal, when a user' S clipping operation on the live video is received, a clipping request for the live video is transmitted to the video distribution server.

In step S42, the video address information transmitted by the video distribution server is received.

The video address information is determined by the video distribution server according to the clipping request, the video address information is address information of a target clipping video including at least one video segment in a preset time period before the live broadcasting moment, the video address information includes sub-video address information corresponding to the at least one video segment, and the target clipping video is a segment of a live video stream with preset duration cached by the video distribution server in the live broadcasting process.

In step S43, the target clip video is acquired based on the video address information.

On the basis of the embodiment shown in fig. 4, in one implementation, before sending the clip request for the live video to the video distribution server, the video clip method applied to the terminal further includes the following steps, step a1 and step a 4:

in step a1, a request to obtain live video from a video distribution server is sent to a source station server.

When a user wants to watch live video by using the terminal, the terminal needs to pull the live video to the video distribution server, at the moment, the terminal can send a request for the video distribution server to acquire the live video to the source station server, so that in the subsequent steps, the source station server can feed back address information of the video distribution server corresponding to the live video to the terminal.

In step a2, address information of a video distribution server corresponding to the live video transmitted by the source station server is received.

Specifically, since the live video and the video distribution server have a corresponding relationship, the source station server can determine the address information of the video distribution server corresponding to the live video after receiving a request for acquiring the live video sent by the terminal. And sending the address information of the video distribution server corresponding to the live video to the terminal.

In step a3, a play request for the live video is sent to the video distribution server according to the address information of the video distribution server, so that the video distribution server sends the live data stream of the live video to the terminal when receiving the play request.

Specifically, after obtaining the address information of the video distribution server of the live video, the terminal may send a play request for the live video to the video distribution server according to the address information of the video distribution server.

In step a4, a live data stream sent by a video distribution server is received.

After receiving a play request of a terminal for a live video, the video distribution server may send a live video stream of the live video to the terminal.

On the basis of the embodiment shown in fig. 4, in an implementation manner, the step S42 of receiving the video address information sent by the video distribution server includes:

and receiving a target file in a preset format sent by the video distribution server.

The target file with the preset format is as follows: the video distribution server is generated according to the sub-video address information corresponding to each video clip in at least one video clip in a preset time period before the live broadcast time, and the target file comprises the sub-video address information.

Specifically, after the video distribution server acquires the sub-video address information corresponding to each video clip in the at least one video clip, the video distribution server may generate the acquired sub-video address information into a target file in a preset format, so that in the subsequent steps, when the video distribution server transmits the video address information to the terminal, the video distribution server may transmit the target file in the preset format to the terminal.

It should be noted that each video clip included in the preset time period before the live broadcast time has a sequential playing sequence. For example, in a preset time period before the live broadcast time, 3 video clips are included, and the playing sequence is video clip 1, video clip 2 and video clip 3 in sequence. Video segment 1 corresponds to the first sub-video address information, video segment 2 corresponds to the second sub-video address information, and video segment 3 corresponds to the third sub-video address information, so that the generated target file may include a sub-video address information sequence composed of the first sub-video address information, the second sub-video address information, and the third sub-video address information. In this way, in the subsequent step, after the video distribution server acquires the target file, the video distribution server may acquire the target clip video according to the sequence of the sub-video address information included in the target file.

Therefore, according to the technical scheme provided by the embodiment, after receiving the clipping request, the video distribution server can determine at least one video segment in a preset time period before the live broadcast time according to the clipping request; acquiring sub-video address information corresponding to each video clip in at least one video clip; and generating a target file with a preset format, wherein the target file comprises sub-video address information corresponding to each video clip in at least one video clip. Therefore, in the subsequent steps, after the terminal receives the target file with the preset format, each video clip in at least one video clip can be obtained according to the sub-video address information included in the target file.

On the basis of the video clipping method applied to the terminal, in an embodiment, receiving the target file in the preset format sent by the video distribution server may include:

Specifically, since the general players all support the m3u8 format, the video distribution server may generate a target file in the m3u8 format, where the target file includes sub video address information corresponding to at least one video clip included in a preset time period before the live broadcast time.

Correspondingly, acquiring the target clip video according to the video address information may include the following steps:

sending a video request to a video distribution server according to the address information of each sub video in the target file in the m3u8 format;

and receiving video clips corresponding to the sub-video address information sent by the video distribution server.

Specifically, after acquiring the target file in the m3u8 format, the terminal may send a video request to the video distribution server according to the sub-video address information included in the target file in the m3u8 format; after the video distribution server obtains the video request, the video distribution server can send the video clips corresponding to the sub-video address information to the terminal, so that the terminal can obtain the video clips corresponding to the sub-video address information.

Since the target file in the m3u8 format includes the sub-video address information corresponding to at least one video clip, after the terminal acquires one sub-video clip according to one sub-video address information, the terminal can simultaneously acquire the next video clip from the video distribution server in the process of previewing the video clip until all the video clips included in the preset time period are acquired, so that the user can watch the highlight video clip which the user wants to clip in time.

On the basis of the video clipping method applied to the terminal, the video clipping method applied to the terminal provided by the embodiment of the present disclosure may further include the following steps, which are respectively step b1 to step b 3:

in step b1, the target clip video is transcoded to obtain a target clip video with a preset video format.

Specifically, since a video file of a live video includes a plurality of video clips, the format of the video clips is generally the FLV format or the TS format. The terminal cannot edit the video segments in the FLV format and the TS format, and can transcode a plurality of FLV format or TS format video segments in the target clip video to obtain the target clip video in the preset video format in order to meet the editing requirements of users on the target clip video. It is understood that the target clip video in the preset video format is composed of a plurality of video segments in the preset video format, and the preset video format may be MP4 format, etc., and the preset video format is not specifically limited in the embodiment of the present disclosure.

In step b2, after the editing instruction of the user for the target clip video in the preset video format is acquired, the editing operation matched with the editing instruction is performed on the target clip video in the preset video format, so as to obtain the edited target clip video.

After the target clip video in the preset video format is obtained, the user can edit the target clip video in the preset video format, and when the user edits the target clip video in the preset video format, the terminal can obtain an editing instruction of the user on the obtained target clip video, and can execute an editing operation matched with the editing instruction, for example, a special effect liked by the user is added to a target video file in the preset video format, so that the edited target clip video is obtained.

In step b3, when an instruction to issue the edited target clip video by the user is acquired, the edited target clip video is transmitted to the video distribution server.

After the terminal obtains the edited target clip video, the user may want to release the edited target clip video. Therefore, the terminal can monitor whether the release instruction of the user to the edited target clip video is obtained in real time, for example, the terminal can monitor whether the user clicks the release button in real time, and when the release button is monitored to be clicked, the terminal obtains the release instruction.

After acquiring a user issuing instruction for the edited target clip video, the terminal can send the edited target clip video to the video distribution server.

Therefore, according to the technical scheme provided by the embodiment, the process of transcoding the target clip video by the terminal can be asynchronously carried out in the background, and the normal use of the terminal and the live broadcast watching of the user are not influenced. After the terminal obtains the target clip video in the preset video format, the terminal can edit the target clip video in the preset video format and distribute the edited target clip video. And, by transcoding the target clip video locally at the terminal, the amount of computation of the video distribution server can be reduced.
