In the process of the above-mentioned directing, when there are unplanned emergency events, such as temporarily inserted advertisements, earthquake, fire alarm, etc., the directing user needs to cut such emergency events into the current video being live in the form of cut-in video, fig. 2 is a schematic diagram of a cut-in video provided by an embodiment of the present disclosure, as shown in fig. 2, the cut-in video is displayed on an upper layer of a current video, in order to reduce the occlusion of the cut-in video to the current video, the cut-in video is usually displayed in the edge or corner area of the current video, however, for example, the cut-in video is a temporarily inserted advertisement, because the cut-in video is located at the edge corner of the current video, the display effect is poor, and if the cut-in video only contains static characters or pictures, the cut-in video cannot attract the attention of the user and is easy to be ignored by the user, so that the cut-in video does not play an ideal role in popularizing and displaying the advertisement information. For the above reasons, in general, a cut-in video with a video special effect is formed by adding a dynamic special effect to information corresponding to an emergency event, such as a temporarily inserted advertisement, so as to improve the presentation effect of the cut-in video, enable the information in the cut-in video to draw sufficient attention of a user, and improve the transmission effect of the information.
In the prior art, in order to add a video special effect to a cut-in video, which can improve the video expressive power of the cut-in video and conforms to the content expressed by the cut-in video, a common method is that after a director user acquires the cut-in video corresponding to an emergency, the cut-in video is added with the video special effect according to manual experience to form a video with a special effect, and then the video with the special effect is added to a current video through a director platform to be displayed. However, adding special effects to the cut-in video manually wastes time and labor, and the real-time playing of the cut-in video is affected, so that the broadcasting effect and the propaganda effect of an emergency with higher real-time requirement are reduced, and the expressive force of the cut-in video is affected.

In the embodiment, by respectively extracting the features of the image data and the audio data in the cut-in video, more content information in the cut-in video can be obtained, and the accuracy of matching the video special effect of the cut-in video is improved.
S102: and fusing the video special effect information into the cut-in video to obtain the special effect video.
Exemplarily, after the video special effect information is determined, the video special effect information is fused into a cut-in video according to a preset characteristic generation method to obtain a special effect video, which is the cut-in video with the video special effect. More specifically, the video effect information may include modifications to the size and position of the cut-in video, and may also include an effect template added to the cut-in video, among other things. The special effect video comprises content information of the cut-in video, and the content information can be better displayed due to the fact that the special effect video is provided with the dynamic special effect, and the display effect is improved.
S103: and rendering the special effect video to the current video for displaying.
Specifically, after the special effect video is obtained, the special effect video is rendered into the current video, an output video is generated, and the current video and the special effect video are simultaneously displayed in the output video. And after the cloud service, the output video is distributed to the live broadcast platform, so that a network user can watch the output video by accessing the live broadcast platform through the terminal equipment.
In the embodiment, in the process of playing the current video, if the cut-in video is detected, video special effect information is determined according to the cut-in video, wherein the video special effect information is used for representing a video special effect matched with the video content of the cut-in video; fusing video special effect information into a cut-in video to obtain a special effect video; and rendering the special effect video to the current video for displaying. By detecting the cut-in video in real time and automatically adding and displaying the video special effect matched with the video content of the cut-in video, the automatic processing and displaying of the burst cut-in video in the video live broadcasting process are realized, manual intervention is not needed, the playing real-time performance of the burst video is improved, and the playing effect and the propaganda effect of the burst video in the live broadcasting process are improved.

s201: and acquiring a video access address through a preset video address channel.
S202: based on the video access address, it is true whether a cut-in video is detected.
Illustratively, the video address channel is a functional module implemented by a software program, and the functional module can output a video access address, and more specifically, the video address channel can receive the video access address sent by other terminal devices, so as to obtain the video access address. In a specific implementation manner, a director user inputs a specific video access address through a cloud director client operating in a terminal device, and the terminal device sends the video access address to a cloud server to be acquired by a video address channel of the cloud server, so as to acquire the video access address.
Further, in the video access address, if a valid video exists, it is determined that a cut-in video is detected, otherwise, it is determined that no cut-in video is detected.
In one possible implementation manner, detecting an incoming video according to a video access address includes:
if the video access address is an effective video address, determining that cut-in video is detected, wherein the effective video address is used for representing a network address capable of accessing and obtaining video data; and if the video access address is an invalid video address, determining that the cut-in video is not detected.
In the embodiment, the problem that the wrong cut-in video is obtained due to the fact that the video access address uploaded by the terminal device is wrong is solved by judging the validity of the video access address.
In another possible implementation manner, before obtaining the video access address of the cut-in video through a preset video address channel, the method further includes: and acquiring the currently detected video through a preset video detection channel. According to the video access address, detecting the cut-in video, comprising:
and if the currently detected video meets the preset requirement, sending the address of the video detection channel to a video address channel, and executing the step of obtaining the video access address of the cut-in video through the preset video address channel.
Fig. 5 is a schematic diagram of a process of obtaining a cut-in video according to an embodiment of the present disclosure, and as shown in fig. 5, a video monitor is in communication connection with a cloud server running a cloud director platform, the video monitor is used for collecting video data, a video detection channel obtains and identifies a data video collected by the video monitor, and after it is determined that the video data collected by the video monitor meets a preset requirement, an access address of the video monitor is sent to a video address channel, so that the cloud server obtains the cut-in video through the video address channel.
More specifically, the video detection channel is a functional module for detecting video content, and more specifically, for example, the video detection channel is connected to a video monitor in communication, and processes the content detected by the video monitor, such as performing video feature recognition, video feature classification, and the like. Because the video monitor is usually in a continuous working state, most of the collected video data is meaningless, after the content detected by the video monitor is processed through the video detection channel, valuable video images are identified, for example, special actions or expressions of strangers intruding and live audiences are detected, that is, if the video detected by the video monitor meets a preset requirement, the video detected by the video monitor is determined as a cut-in video, the address of the video detection channel is sent to the video address channel, and a step of obtaining a video access address of the cut-in video through the preset video address channel is executed, that is, after the address of the video detection channel is obtained by the video address channel, the video images which are collected by the video monitor and meet the preset requirement are obtained through the address.
In the embodiment, a large number of videos detected by a video monitor are processed and screened through a preset video detection channel, so that valuable video data are obtained, automatic cut-in video obtaining is achieved, a director does not need to manually input a video access address through terminal equipment to obtain the cut-in video, the automation degree of the cloud director platform for obtaining the cut-in video and the quality of the cut-in video are improved, and the timeliness of displaying the cut-in video is further improved because the cut-in video does not need to be manually screened.
S203: in the process of playing the current video, if the cut-in video is detected, feature extraction is carried out on the cut-in video to obtain feature information, and the video category is determined according to the feature information.
S204: the method comprises the steps of obtaining video content of a current video, and determining video special effect information according to the video content of the current video and video types.
For example, to improve the video performance, the video special effect needs to be matched with the cut-in video itself and the content played by the current video. If the video special effect of the cut-in video does not match with the video content of the current video, the understanding obstruction and the understanding deviation can be generated on the meaning expressed by the cut-in video and the meaning appearing at the moment when a viewer watches the cut-in video, so that the understanding of the viewer on the information really wanted to be expressed by the cut-in video is influenced, even the sense of incongruity is generated, and the expressive force of the cut-in video is influenced.
In the step of the embodiment, after the cloud server extracts and classifies the features of the cut-in video and determines the video category, the video special effect information is determined according to the video category of the cut-in video and the video content of the current video.
S205: and fusing the video special effect information into the cut-in video to obtain the special effect video.
S206: and acquiring the video content of the current video.
S207: and determining display parameters according to the video content of the current video.
S208: and rendering the special effect video to the current video according to the display parameters, generating an output video, and displaying the output video on the director window.
Optionally, the display parameters include one or more of: displaying position, displaying size and dynamically displaying track. After the special effect video is obtained, before the special effect video is displayed in the current video, the display parameters of the special effect video also need to be determined. Such as display position, display size, dynamic display trajectory, etc. In order to reduce the shielding of the special effect video on the current video and improve the expressive force of the special effect video, the display parameters of the special effect video need to be determined according to the content of the current video. Specifically, for example, according to the video content of the current video, the video content of the current video is divided into an important content area and a non-important content area in units of one frame image in the current video, and information such as the size and the dimension when the special effect video is displayed in the non-important area is determined as the display parameter.
In the embodiment, the display parameters are determined according to the video content of the current video, so that the special effect video can be displayed at a proper position in the current video, the effective information of the current video is prevented from being shielded, and the expressive force of the special effect video can be improved.
Optionally, after step S208, the present embodiment further includes:
s209: and acquiring a stopping instruction, wherein the stopping instruction is used for instructing and controlling the special effect video to stop displaying on the current video.
S210: and controlling the special effect video to stop displaying on the current video according to the stop instruction.
Exemplarily, after the special effect video is rendered to the current video and the output video is generated, one side of the terminal device can display the output video in real time through the cloud director client, if a director user on the side of the terminal device is unsatisfied with the video characteristic pattern in the special effect video, a stop instruction can be sent to the cloud server through the terminal device, and the cloud server obtains the stop instruction or stops displaying the stop special effect video on the current video, so that the influence on the live broadcast of the current video due to unreasonable video special effect matching of the cut-in video is avoided, live broadcast accidents are avoided, and the expressive force of the live broadcast of the video is improved.
