Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, the application scenario involves a signal acquisition device 101, a server 102, and a recording device 103.
The signal acquisition device 101 acquires audio and video data of a live broadcast site to obtain a live broadcast video stream. The live broadcast site can broadly include an offline live broadcast site and an online live broadcast site, for example, a government affair public meeting, a public audiences conference, a court trial live broadcast, a officer examination training, a product release meeting, an enterprise meeting, an industry meeting, an exhibition live broadcast and the like.

For example, providing storage, computing, and processing services.
The recording device 103, such as a Digital Video Recorder (DVR), can record and store audio and Video information, including but not limited to a Video camera, a Video Recorder, a computer, and a mobile phone.
The recording device 103 automatically generates a video file when the acquired video stream is over or interrupted.

The technical solution of the present application will be explained with reference to specific examples. It should be noted that the following several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a first flowchart of a live video processing method according to an embodiment of the present application. As shown in fig. 2, the live video processing method includes: in the live broadcasting process, the following operations are executed to obtain a video file:
s201: and recording the live video stream, and detecting whether the live video stream is interrupted.
Video streaming refers to the transmission of video data that can be handled as a steady and continuous stream through a network. A live video stream is a video stream captured from a live scene. Illustratively, a live video stream can be obtained by pushing a collected live video source to a recording module by a director platform, and the recording module records the pushed live video stream. The recording module continuously detects whether the live video stream is interrupted while recording the live video stream. Illustratively, when the recording module detects that the video stream is not received within a specified time, it is determined whether the live video stream is interrupted.
S202: and responding to the detection of the interruption of the live video stream, switching to the standby video stream for recording, and detecting whether the live video stream is recovered.
The standby video refers to a standby video which is recorded before live broadcast and is used for replacing and playing when the live broadcast has an emergency condition so that the live broadcast cannot be normally carried out. For example, the content of the standby video may be the same as or similar to the live content of the live broadcast, such as a related lecture video or a previously recorded live broadcast video, and may also be unrelated video content such as an advertisement, a black screen, or a white screen. The duration of the standby video may be longer than the duration expected from the live site to provide sufficient standby video streaming; or a short video, which is scrolled as the method is performed to provide a sufficient standby video stream.
The standby video can be stored in the cloud in advance, or stored in other storage media which can be processed into a video stream. In the embodiment of the application, when interruption of a live video stream is detected, the recording module is switched to a standby video stream for recording.
Optionally, in response to detecting that the live video stream is interrupted, the method for switching to the standby video stream for recording may include: acquiring a standby video stream, and traversing video frames in the standby video stream from the recording start moment, wherein the traversing and the recording are synchronous; in response to detecting interruption of the live video stream, determining a traversed target position in the standby video stream; and switching the standby video stream to record based on the target position.
Where video is composed of still pictures, each still picture may be referred to as a video frame. The frames of each video frame include specific recognizable elements and corresponding time instants, which can be obtained during traversal. The target position may refer to a position in a time dimension, for example, in an embodiment where a process of the standby video is substantially the same as a live broadcast process of a live broadcast site, the target position may refer to a position of a video frame in the standby video corresponding to a live broadcast video stream interruption time, and considering that some unpredictable time delay or advance exists in the live broadcast site, the target position may have a small difference in time with content of the standby video, and thus the target position may also refer to a position of a video frame in the standby video at a time near the live broadcast video stream interruption time.
The target position may refer to a position in a content dimension, for example, in an embodiment where the content of the standby video is substantially the same as the live content of the live broadcast site, the target position may refer to a position of a video frame corresponding to the content at the time of interruption of the live video stream in the standby video.
Optionally, the method for acquiring the standby video stream may include: determining the similarity of each video stream and a live video stream in a plurality of video streams; and determining the video stream with the similarity meeting the similarity requirement as the standby video stream. In this embodiment, the standby video may be one. Or a plurality thereof. And when the interruption of the live video stream is detected, selecting one of the one or more standby videos as a standby video for switching recording. Optionally, the multiple standby videos may be divided into different categories in advance, and may be identified with identifiable codes, and when determining the similarity between the standby video stream and the live video stream, a preliminary determination may be performed according to the codes.
Optionally, a plurality of video frames of the standby video may also be acquired, and the determination may be performed according to the content of the video frames. For example, a video stream between similar video frames is selected as the standby video stream. In some further embodiments, a depth algorithm may also be used to determine the similarity of each standby video stream to the live video stream. The similarity requirement may be set to be the highest similarity of the standby video stream, or may be set to be the similarity exceeding a set threshold, which is not limited herein.
In addition, whether the live video stream is recovered or not is continuously detected during the period of switching to the standby video stream for recording.
S203: and switching to the live video stream for recording in response to the detection of the recovery of the live video stream.
And when the recovery of the live video stream is detected, switching to the live video for recording. That is, the live video stream is recorded preferentially, and the live video stream is switched to be recorded and prepared within the time when the live video stream is interrupted, so that the video stream acquired in the recording stage is ensured to be continuous in time.
In the embodiment of the application, in the live broadcasting process, the following operations are executed to obtain a video file: recording a live video stream, detecting whether the live video stream is interrupted, switching to a standby video stream for recording in response to detecting that the live video stream is interrupted, detecting whether the live video stream is recovered, and switching to the live video stream for recording in response to detecting that the live video stream is recovered. Through the method and the device, a video file can be generated by directly recording in the live broadcast recording process, later-stage merging operation is not needed, time consumption is saved, and watching-back experience of recorded videos is enhanced. Specifically, a plurality of video files generated by interruption of the recording process are recorded, recording is stopped due to the interruption, and then new recording is started, so that time loss exists in the period, the total duration of the combined plurality of video files is shorter than the total duration of the actual live broadcast process due to the loss, the duration of the video files obtained by the live broadcast video processing method is the same as the live broadcast duration of the live broadcast site, and the problems of short duration and disordered time sequence are solved.
On the basis of the foregoing embodiment, optionally, in response to detecting that the live video stream is interrupted, the method for switching to the standby video stream for recording may further include: in response to detecting that the live video stream is interrupted, determining the video stream related to the recorded content as a standby video stream according to the recorded content before the interruption moment; and switching to the standby video stream for recording. In this embodiment, when it is detected that a live video stream is interrupted, a recorded content before the interruption time is obtained, a category of the recorded content is identified and determined, and a video stream related to the content is matched in a standby video stream as a standby video stream.
Optionally, the method for determining, according to the recorded content before the interruption time, that the video stream related to the recorded content is a standby video stream may include: identifying the recorded content to obtain an identification result; determining a target object related to the recognition result, wherein the target object comprises at least one of a document, a questionnaire, interactive content which may exist and a multimedia object; and determining the video stream related to the target object as a standby video stream.
The interactive content may include on-site questions, questionnaires, barrage messages and the like, and the multimedia objects may include lectures, songs, advertisements and the like, and may also be white screens or black screens and the like. The switching recording is carried out by acquiring the video stream related to the recorded content from the standby video, so as to further improve the fluency of the recorded video file during review and improve the review experience.
In other embodiments, the number of standby video streams involved in the live video processing method provided by the present scheme is at least one, and the method further includes: if the complete broadcast video stream is recorded and whether the broadcast video stream is recovered is not detected, executing the following operations: circularly recording and preparing a broadcast video stream; and switching to other standby video streams of the at least one standby video stream for recording. Therefore, in a related review scene, various interactions in live broadcast such as chat, document operation, whiteboard operation and the like can be associated according to the video playing time sequence, and the live broadcast process is more truly restored.
Fig. 3 is a schematic flow diagram of a live video processing method according to an embodiment of the present application, which is used to additionally explain the above-mentioned method embodiment. As shown in fig. 3, in the method, an alternative video file (i.e., alternative video) may be uploaded to a server, and an alternative video source is streamed from the server to a live recording module (i.e., recording module); the anchor video source (also called live video source) is pushed to the live recording module by the director, specifically, the video of the live broadcast site can be collected and sent to the server, the anchor video source is pushed to the live recording module by the slave server, and the live recording module records and generates a video file.
The live broadcast recording module is set to preferentially acquire the push stream (namely, live broadcast video stream) of the main broadcast video source and record the video, and when the push stream of the main broadcast video source is interrupted, the live broadcast recording module immediately acquires the push stream of the standby broadcast video source from the server and records the continuous video. And when the push stream of the main broadcast video source is recovered, the live broadcast recording module is immediately switched to acquire the push stream of the main broadcast video source and continuously records. Therefore, under the seamless switching of the plug flow of the main video source and the standby video source, the recording is not interrupted, and only one video file is produced all the time. In addition, the standby video source is an independent video source, so that the recording interruption caused by the fault problem of a director end (director equipment or a director platform) is effectively avoided.
