It should be noted that, the information (including but not limited to user equipment information, user personal information, etc.), data (including but not limited to data for analysis, stored data, presented data, etc.), and signals related to the present disclosure are all authorized by the user or are fully authorized by the parties, and the collection, use, and processing of relevant data is required to comply with relevant laws and regulations and standards of relevant countries and regions. For example, live recorded video and the like referred to in the embodiments of the present disclosure are all acquired with sufficient authorization.
Fig. 1 is an environmental schematic diagram of an implementation of a live broadcast method according to an embodiment of the disclosure. As shown in fig. 1, the implementation environment includes: the terminal 101 and the server 102 are directly or indirectly connected by wired or wireless communication between the terminal 101 and the server 102, which is not limited.
The terminal 101 is at least one of a smart phone, a smart watch, a desktop computer, a laptop computer, a virtual reality terminal, an augmented reality terminal, a wireless terminal, and a laptop portable computer. Terminal 101 may be referred to generally as one of a plurality of terminals, with embodiments of the present disclosure being illustrated only by terminal 101. Those skilled in the art will recognize that the number of terminals may be greater or lesser. Illustratively, the terminal 101 can be provided with an application program for providing a time-lapse live broadcast function, such as a live broadcast type application program (also referred to as a live broadcast platform), a video type application program, and the like, which is not limited thereto.
The server 102 is an independent physical server, may be a server cluster or a distributed file system formed by a plurality of physical servers, and may be a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligence platforms, and the like. The number of servers 102 may be greater or lesser, and embodiments of the present disclosure are not limited in this regard. The server 102 is illustratively used to provide background services for applications running on the terminal 101. Illustratively, taking a live broadcast application program running on the terminal 101, the server 102 is configured to provide a background service for the live broadcast application program, where a target object (such as a related person responsible for live broadcast) can trigger the terminal to receive a live broadcast signal (i.e. an audio/video signal) of a live broadcast through the live broadcast application program, record the live broadcast signal, obtain a live broadcast recorded video, and delay and live broadcast the live broadcast recorded video through the server 102, so as to facilitate viewing of the live broadcast video of the live broadcast by a viewer. Of course, server 102 may also include other functional servers to provide more comprehensive and diverse services, which are not limited.
Based on the above implementation environment, the live broadcast method provided by the embodiment of the present disclosure is described below.
Fig. 2 is a flowchart of a live broadcast method provided in an embodiment of the present disclosure. As shown in fig. 2, the live broadcast method is performed by a terminal, and includes the following steps 201 to 204.
In step 201, the terminal plays an un-live video of the live recorded video, where the un-live video includes a video segment of the live recorded video that is not subjected to delayed live broadcast.
In the embodiment of the present disclosure, live recorded video refers to video obtained by recording live broadcast signals (i.e., audio/video signals) on live broadcast sites, for example, a concert site, a conference site, a evening site, and a sports event site, which are not limited thereto. The terminal is provided with a target application program providing a time-delay live broadcast function, relevant personnel can carry out time-delay live broadcast on live broadcast recorded video through the target application program, accordingly, the terminal plays non-live broadcast video on an application interface of the target application program so as to be convenient for relevant personnel to check, and it is understood that the time-delay time length of the terminal for time-delay live broadcast based on the live broadcast recorded video can be set according to requirements, and the time-delay time length is not limited. For example, taking a delay time of 5 minutes as an example, in a case where the real time of the live broadcast is 18:05, the real time of the current playing segment of the video being broadcast is 18:00 through delay live broadcast, and the video segment with real time between 18:00 and 18:05 is not broadcast, that is, the video segment with no delay live broadcast in the live broadcast recorded video.
In step 202, the terminal displays an edit track for the non-live video.
In an embodiment of the present disclosure, the editing track is used to edit video clips in the live video. The terminal displays the editing track for the non-live video on the application interface of the target application program, for example, the terminal displays the editing track below the playing area of the non-live video on the application interface, which is not limited. The terminal can synchronously display the editing track aiming at the live video and the non-live video under the condition of playing the live video and the non-live video; the editing track can also be displayed in response to the triggering operation of the video editing control on the application interface under the condition of playing live video and non-live video, which is not limited.
In step 203, the terminal responds to the editing operation of the target video segment on the editing track, and generates the edited non-live video, wherein the target video segment refers to the video segment meeting the filtering condition of the live content.
In the embodiment of the present disclosure, the editing operations include a deleting operation, a replacing operation, and a volume editing operation, which will be described in detail in the embodiment shown in fig. 3, which will not be described herein. The live content filtering condition means that the content of the live video does not meet the live requirement or is not compliant, and the live content comprises sound content and image content. For example, if the sound content of a video clip includes a sensitive word, or the image content includes a sensitive image, the video clip meets the live content filtering criteria. It should be understood that the specific form of the live content filtering condition can be set according to actual requirements, which is not limited.
In step 204, the terminal performs live broadcasting with time delay based on the edited live video.
In the embodiment of the disclosure, after editing the target video segment meeting the live content filtering condition, delay live broadcasting is performed based on the edited non-live video, so that the finally broadcasted live video meets the live broadcasting requirement, and the safety of the live broadcasting content is ensured.
In summary, in the live broadcast method provided by the embodiment of the disclosure, by playing the live broadcast video of the live broadcast recorded video, relevant personnel can find out the target video segments meeting the live broadcast content filtering conditions in the live broadcast video in time, and further, by displaying the editing track aiming at the live broadcast video, relevant personnel can edit the target video segments in time, so that delayed live broadcast is performed based on the edited live broadcast video. By the method, the light live broadcast method is provided, man-machine interaction efficiency can be effectively improved on the basis of ensuring the compliance of live broadcast contents, and live broadcast cost is greatly reduced.
Fig. 2 above presents a simplified flow of a live broadcast method provided by an embodiment of the present disclosure. The live broadcast method will be described in detail based on the embodiment shown in fig. 3.
Fig. 3 is a flowchart of another live method provided by an embodiment of the present disclosure. As shown in fig. 3, the live broadcasting method is performed by a terminal, and includes the following steps 301 to 306.
In step 301, the terminal records the received live broadcast signal on the live broadcast spot, and obtains a live broadcast recorded video.
In the embodiment of the disclosure, the terminal is in communication connection with the live broadcast equipment on the live broadcast by a wired or wireless mode, and the live broadcast signal on the live broadcast is sent by the live broadcast equipment, for example, the live broadcast equipment is a broadcast guiding station equipment, which is not limited. The terminal is schematically provided with and runs a target application program for providing a time-delay live broadcast function, and a target object (such as a related person responsible for live broadcast) can trigger the terminal to record a received live broadcast signal on a live broadcast site through the target application program so as to obtain a live broadcast recorded video.
In some embodiments, the terminal is configured with a capture card (a capture device that captures analog signals such as external photoelectricity, video, audio, etc., and digitally directs the analog signals to a computer for digital processing, including an image capture card, a video capture card, an audio capture card, etc.), the live broadcast device processes real-time signals (i.e., audio and video signals) of the live broadcast to obtain Program video signals (Program, PGM), also referred to as Program bus, of the live broadcast, the PGM signals of the live broadcast are sent to the terminal through a digital component serial interface (Serial Digital Interface, SDI) interface, and the terminal records the PGM signals of the live broadcast through the capture card to obtain live broadcast recorded video. It should be understood that the process of recording the live broadcast signal by the terminal is a process of storing the live broadcast signal on the live broadcast site.
In step 302, the terminal performs time-delay live broadcast on the live broadcast recorded video to obtain a live broadcast video.
In the embodiment of the disclosure, the terminal is in communication connection with a server in a wired or wireless manner, and the server is used for providing background service for a target application program running on the terminal. Schematically, the terminal responds to the time-delay live broadcast operation of the live broadcast recorded video, generates the live broadcast video based on the time-delay time length corresponding to the time-delay live broadcast operation, and sends the live broadcast video to the server (namely, live broadcast push stream) to realize time-delay live broadcast. The delay time can be set according to requirements, and will not be described herein.
In step 303, the terminal plays live recorded video, live video, and non-live video.
In the disclosed embodiments, the video segment of the live video follows the currently playing segment of the live video. And the terminal plays the live broadcast recorded video, the live broadcast video and the non-live broadcast video on an application interface of the target application program. By synchronously playing the videos on the application interface, relevant personnel can conveniently and clearly see live videos on the live broadcast site, live videos which are played and non-live videos which are not played temporarily, so that the man-machine interaction efficiency is improved, and the user experience is improved.
In step 304, the terminal displays an edit track for the non-live video.
In the embodiment of the present disclosure, the step 304 is the same as the step 202 in the embodiment shown in fig. 2, and thus will not be described again.
In some embodiments, the terminal also displays a recording track of the live recorded video and a playout track of the live video. Through displaying the recording track and the broadcasting track, relevant personnel can clearly know the difference between the live broadcast recording condition and the live broadcast broadcasting condition, and therefore the man-machine interaction efficiency is improved. It should be noted that, the broadcast track of the live video and the edit track of the non-live video may be displayed on the basis of the same track, or may be displayed separately, which is not limited thereto. For example, referring to fig. 4, fig. 4 is a schematic diagram of an application interface provided in an embodiment of the present disclosure, taking a broadcast track of a live video and an edit track of an un-live video as shown in fig. 4, for example, where the broadcast area 401 of the application interface 400 plays live recorded video (i.e. a real-time signal), live video (i.e. a broadcast signal), and un-live video (i.e. an edit signal), and the record track and the target track of the live recorded video are displayed in the edit area 402, where the target track includes the broadcast track of the live video and the edit track of the un-live video (i.e. a broadcast+edit track). On the target track, the video segments before the broadcasting time axis belong to live videos, and the video segments after the broadcasting time axis belong to non-live videos.
It should be understood that, in the process of time-lapse live broadcasting, steps 301 to 304 are synchronously performed, that is, when the terminal receives the live broadcast signal, the terminal records the live broadcast recorded video, performs time-lapse live broadcasting, and synchronously plays the live broadcast recorded video, the live broadcast video and the non-live broadcast video on the application interface, so that the relevant personnel can clearly see the whole time-lapse live broadcast condition, and thus, the relevant personnel can edit the target video segment in time when the target video segment meeting the live broadcast content filtering condition appears in the non-live broadcast video, so that the edited non-live broadcast video meets the requirement in the live broadcast, and the editing process of the target video segment is described in detail through step 305.
In step 305, the terminal responds to the editing operation on the target video segment on the editing track, and generates the edited non-live video, wherein the target video segment refers to the video segment meeting the filtering condition of the live content.
In the embodiment of the disclosure, the target video segment includes at least one video frame, and the terminal is used for editing the at least one video frame in response to the editing operation of the at least one video frame in the target video segment to generate the edited non-live video. In this way, real-time editing in frame units can be realized, improving the accuracy of video editing. In addition, as is known from the foregoing step 203, the editing operation includes a deletion operation, a replacement operation, a volume editing operation, and the like, which are described below, respectively.
First, delete operation.
Schematically, the terminal responds to the deleting operation of the target video segment on the editing track to delete the target video segment, and the edited non-live video is obtained. In some embodiments, the terminal displays a plurality of editing options in response to a positioning operation of a target video clip on the editing track, and deletes the target video clip in response to a triggering operation of a deletion option in the plurality of editing options, so as to obtain an edited non-live video. For example, referring to fig. 5, fig. 5 is a schematic diagram of an editing operation provided by an embodiment of the present disclosure. As shown in fig. 5, the terminal displays an editing track of the live video in the editing area 402 of the application interface 400, the terminal responds to the positioning operation of the target video segment 501, displays a plurality of editing options 502, responds to the triggering operation of the "delete" option in the plurality of editing options, deletes the target video segment 501, and obtains the edited live video.
