Fig. 2 is a flowchart illustrating a method for processing dubbing information in a video commentary according to another embodiment of the present invention. As shown in fig. 2, the method may further include the following steps based on the above steps 11 to 14:

step 21, obtaining a social relationship list of the first target audience, where the social relationship list includes at least one second target audience, and the second target audience is in a friend relationship with the first target audience;

specifically, a social relationship list of the first target audience is obtained, and a friend circle of the first target audience is created and maintained. The friend circle at least comprises a second target audience which is friend to the first target audience. The friend circles include self-built friend circles, WeChat friend circles and QQ friend circles but are not limited to the friend circles.

Step 22, pushing a third target video segment of which the second target audience has finished the commentary dubbing in the social relationship list to the first target audience;

specifically, after the second target audience completes dubbing, the third target video explained by the second target audience can be stored and downloaded, so that subsequent sharing is facilitated. And after the third target video is synthesized, the third target video is automatically pushed to the first target audience according to the friend circle of the second target audience.

Step 23, synthesizing the third target video segment and the second target video segment to obtain a playing video stream, and further, outputting the playing video stream to a playing device that plays the video data.

Specifically, after the second target audience completes dubbing, the comment fragments of the friends circle of the second target audience are preferentially selected for synthesis according to the friends circle of the social relationship of the second target audience. And secondly, preferentially selecting the comment audio track and the video track of the second target audience friend to synthesize and play the video stream in real time according to the friend ring of the second target audience, and sending the video stream to the audience player through a streaming media protocol. And finally, when the user switches the commentator, the player interacts with the server, the server end switches the audio track of the commentator, synthesizes a new video stream, and sends the new video stream to the players of the audiences to realize the switching of the commentator.

In still another alternative embodiment of the present invention, step 14 may be further followed by:

step 17, obtaining a social relationship list of the first target audience;

step 18, if the social relationship list is empty or there is no third target video segment of the commentary dubbing completed by the second target audience in the social relationship list, pushing a fourth target video segment of the commentary dubbing of a preset commentator segment to the first target audience, and synthesizing the fourth target video segment and the second target video segment to obtain a played video stream.

Specifically, the preset commentator segment commentary dubbing comprises the commentator segment with the highest system score, but is not limited to the above.

In this embodiment, the social relationship list of the first target viewer is first obtained, and if there is no commentary fragment that can be used in the friend circle, a preset commentator fragment is used for filling. (for example, the event a is divided into three sections, namely a, b and c, wherein a king explains the section b, and when the king downloads the event a explained by itself, whether friends of the king exist in the explanation corresponding to the section a and the section c can be judged firstly, if yes, explanation sections of the friends of the king are selected preferentially to be synthesized, and if not, the section b and the section c are filled with the commentator section with the highest system score). And finally, when the user switches the commentator, the player interacts with the server, the server end switches the audio track of the commentator, synthesizes a new video stream, and sends the new video stream to the players of the audiences to realize the switching of the commentator.

In this embodiment, the synthesizing of the audio information is to synthesize all the commentator audio contained in the second target video segment and the third target video into the video file at one time, and then issue the mapping relationship of the commentator audio track number to the player. The player selects and plays the audio track according to the mapping relation. When the user switches the commentator, only the corresponding audio track needs to be switched. The image information is synthesized by issuing a real-time synthesized streaming media file through a server. The server selects the video track and the audio track corresponding to the best commentator, synthesizes and plays the video stream in real time, and sends the video stream to the players of the audiences through a streaming media protocol. When the user switches the commentator, the player interacts with the server, the server end switches the audio track of the commentator, synthesizes a new video stream and sends the new video stream to the players of the audiences.

The processing method of the video commentary dubbing information provided by the above embodiments of the present invention can be applied to a terminal device equipped with a touch panel, and for convenience of description, the following steps are mainly performed by way of example, but are not limited thereto.

As shown in fig. 3, first, the user enters the event video interface, and clicks the "add commentary" button, the server may automatically match the optimal commentary fragment according to the user information and the tag of the commentator.

As shown in fig. 4, next, the user enters the video interface to be explained, the top left side shows the user information to be currently involved in the explanation, the right side shows all the commentators of the current clip, the bottom shows the progress bar of the current clip, and the "start" button.

As shown in fig. 5, when the user clicks the "start" button, the button pattern becomes "complete", and the user can start explaining according to the video content, and the user can finish clicking after saying. If the recording scene is recorded and played, the user can drag the progress bar at the bottom to explain again, so that the multi-time recording is supported, and for the live scene, the user can only explain according to the real-time progress.

As shown in fig. 6 and 7, if the user wants to use the comments of other people, the user needs to enter the comment fragment, click "50 people in total and comment" to view all the comment member information (the commentator with friend relationship is preferentially shown), then click a certain user avatar, the current video can play the comment of the user on the video, and when trying to listen to the comments of other people, the comment content can be "liked". Clicking the head portrait again, returning to the self to start the self explanation, enabling the user to return to any position in the recorded scene, enabling the live scene to acquire the current progress in real time, enabling the server to acquire the audio information explained by the user in real time, and filtering the sensitive information.

Finally, after the user completes dubbing, the user can store and download the game video explained by the user so as to facilitate subsequent sharing. And the synthesis of the complete video preferentially selects the comment segments of the friends circle of the user to synthesize according to the friends circle of the user. And if no commentary fragment can be used in the friend circle, filling the commentator fragment with the highest system score.

As shown in fig. 8 and 9, in addition to this, when a user watching an event enters the event video interface, how many people explain each video segment, and the user is recommended the highly rated instructor by default. The viewing user can select a different commentator for each video segment and can "like" the commentator, promoting the commentator's goodness. After the user finishes watching the whole game, a unique comment video is formed. The selection of each user on the current commentator is transmitted to the background server, the next user enters the current event again, and the server recalculates the commentator intelligently recommended by each segment according to the big data.

In the above embodiment of the present invention, by acquiring video data and user information of a first target viewer watching the video data; segmenting the video data to obtain a video segment; determining a first target video segment matched with the user information from the video segments; and synthesizing the commentary dubbing information of the first target video segment and the first target video segment by the first target audience to obtain a second target video segment. The method and the device have the advantages that the user can select the explicator, the problem that the user can only passively receive the information explicated by one explicator and cannot make other selections is solved, the personalized requirements of the user are met, and the participation sense of the user is improved. Meanwhile, when a user enters a very hot video, the server can recalculate the commentator intelligently recommended by each segment according to the big data, so that the optimal recommendation and explanation effects are achieved, thousands of people and thousands of faces of event explanation contents are formed, the personalized explanation requirements of the user are met, the interest and participation of audiences are aroused, and the enthusiasm and spirits of the whole population are stimulated.
