With continued reference to fig. 2, a flow 200 of one embodiment of a method for live video stream processing according to the present application is shown. The video stream processing method aiming at the live broadcast is used for a terminal and can be used for the terminal, and the method comprises the following steps:
In this embodiment, an execution body (for example, the terminal device shown in fig. 1) on which the live video stream processing method operates may capture a live video stream when receiving a command to start playing a live video stream from a main terminal. The playback instruction here refers to an instruction to start live broadcasting. Such as may be generated by a user activating a play key. The anchor terminal indicates that the user of the terminal is the anchor of the live broadcast. Specifically, the live video stream is a picture taken by a camera of the anchor terminal or a camera connected to the anchor terminal. The broadcast instruction here may be generated by a broadcast operation of a user of the terminal. In practice, the terminal in the present application may be an anchor terminal. The corresponding live broadcast of the live broadcast room is the live broadcast indicated by the live broadcast video stream.
The processed live video stream sent to the viewer terminal may be obtained by processing a shot video stream, that is, an original video stream, by the server. The processing herein may refer to a video stream to which a variety of display contents are added. Such as display content to which at least one of the following is added: barrage and advertisement. The processed live video stream is a live room picture.
In this embodiment, the execution main body may obtain a recorded broadcast instruction during the live broadcast, so as to start to extract an obtained live broadcast video stream, and use a formed extraction result as a recorded broadcast video stream. The recording and playing instruction may be generated by a recording and playing operation of a user, or may be generated by the execution main body in response to the terminal starting a live broadcast, for example, locally generated by receiving a playing instruction.
And step 203, responding to the operation of adding the item link in the live broadcast process, and acquiring the item link.
In this embodiment, the executing body may obtain the item link in response to monitoring that an item adding link operation of the user is received in a live broadcast process.
And 204, in response to the recorded broadcast stopping instruction, stopping extracting the live broadcast video stream to obtain a target recorded broadcast video stream, generating a video file corresponding to the target recorded broadcast video stream, and performing association processing on the video file and the article link.
In this embodiment, the execution main body may stop extracting the live video stream when the recording stop instruction is obtained from the target terminal, and record the live video stream extracted in the whole process as the target recording video stream from the start of extracting the live video stream to the stop of extracting the live video stream. In practice, the execution body described above may perform the association processing in various ways. For example, the video file and the item link are sent to the server, and the server stores the video file and the item link in association with each other.
In practice, the target recorded video stream may be associated with only one item link, or may include video stream segments associated with at least two item links, respectively.
In the method provided by the embodiment of the application, the terminal can extract the video shot by the anchor in the live broadcasting process and the item link recommended by the anchor, so that the extracted video and the item link can be released together subsequently. And the published content comprises an item link associated with the video file, so that a viewer watching the video can purchase an item recommended by the anchor in the video file through the item link. Meanwhile, the embodiment can also avoid the problem that the watching experience of recorded and broadcast videos is influenced due to excessive contents in the pictures brought by directly extracting the pictures of the live broadcast room.
In some optional implementations of the present embodiment, the target recorded video stream includes a plurality of video stream segments respectively associated with a plurality of item links.
In these implementations, the target recorded video stream may include a plurality of video stream segments, i.e., sub-video streams. Each video stream segment corresponds to, i.e. is associated with, an item link.
The implementation modes can acquire a plurality of video stream segments, so that the video stream segments associated with the item links can be comprehensively extracted in one live broadcast.
In some optional application scenarios of these implementations, the associating the video file with the item link in step 204 may include: splitting the video file into sub-video files respectively associated with different item links, wherein each sub-video file is associated with a video stream segment.
In these optional application scenarios, the execution subject may split the video file into at least two sub-video files. Each sub-video file is associated with an item link and different sub-video files are associated with different item links.
In practice, the execution body described above may be split in various ways. For example, the execution subject may use the end time of displaying the item link as the time point of splitting different sub video files, that is, use the end time as the end time point of the sub video file corresponding to the item link, and use the next time point of the end time as the start time point of the next sub video file adjacent to the sub video file.
The application scenes can determine the sub-video file corresponding to each article link by splitting the video file, so that the article links and the sub-video files corresponding to different articles can be respectively published.
Optionally, the splitting the video file into sub video files respectively associated with different item links may include: acquiring an image identification result of a video frame in a video file; and splitting the video file according to different identification results to obtain at least two sub-video files, wherein the different identification results comprise different labels of target articles, and the different target articles are respectively articles indicated by different article links.
Specifically, the execution main body or other electronic devices may perform image recognition on a video frame in a video file, so that the execution main body may split the video file into at least two sub-video files according to different recognition results. The other electronic device here is an electronic device which is connected in communication with the execution main body described above.
Several objects may be presented in the video frame, wherein one object is a target item, i.e. an item recommended by the anchor. In the different recognition results, there may be an identification tag of the same object, such as an identification tag of a face of the anchor, or there may be an identification tag of a different object, where the different object may be an item recommended by the anchor. For example, one target item recommended by the anchor is a pencil, and in the image recognition result of the video frame where the pencil is located, the identification label corresponding to the pencil is "1". The next target item recommended by the anchor is an eraser, and in the image recognition result of the video frame where the eraser is located, the identification label corresponding to the eraser is '2'.
The application scenes can accurately split the video file through image recognition.
In some optional implementations of this embodiment, the associating processing of the video file and the item link in step 204 above may include: acquiring video publishing information, wherein the video publishing information is used for indicating whether the video file is published; and in response to the fact that the video publishing information indicates that the video file is published, the video file is published in association with the item link, wherein a shopping cart identifier associated with the item link is presented in a video playing interface of the published video file.
The execution subject may perform the association distribution in a case where the acquired video distribution information indicates that the video file is distributed. Specifically, the execution main body may acquire video distribution information using various information, and the execution main body may acquire the video distribution information from a local or other electronic device (such as a server), where the video distribution information may be information stored in advance on a terminal or a server.
The implementation modes can automatically carry out associated publishing on the video file and the item link through the video publishing information.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the video stream processing method for live broadcasting according to the present embodiment. In the application scenario of fig. 3, in response to receiving a play instruction 302 of a terminal, an execution main body 301 obtains a live video stream by shooting, and sends a stream pushing request to a server, so that the server pushes the live video stream or a processed live video stream to a viewer terminal in a live broadcast room. The execution body 301 starts extracting the live video stream to form a recorded broadcast video stream in response to acquiring the recorded broadcast instruction 303. The execution main body 301 acquires the item link 304 in response to monitoring that an item link operation is added in the live broadcast process. In response to acquiring the recording stop instruction 305, the execution main body 301 stops extracting the live video stream to obtain a target recording and playing video stream 306, generates a video file 307 corresponding to the target recording and playing video stream, and performs association processing 308 on the video file 307 and the item link.

The anchor terminal indicates that the user of the terminal is the anchor of the live broadcast. Specifically, the live video stream is a picture taken by a camera of the anchor terminal or a camera connected to the anchor terminal. The broadcast instruction here may be generated by a broadcast operation of a user of the terminal.
In this embodiment, the execution main body may obtain a recorded broadcast instruction during the live broadcast, so as to start to extract an obtained live broadcast video stream, and use a formed extraction result as a recorded broadcast video stream. The recording and playing instruction may be generated by a recording and playing operation of a user, or may be generated by the execution main body in response to the terminal starting a live broadcast, for example, locally generated by receiving a playing instruction.
And 403, responding to the operation of adding the item link in the live broadcast process, and acquiring the item link.
In this embodiment, the executing body may obtain the item link in response to monitoring that an item adding link operation of the user is received in a live broadcast process.
And step 404, in response to the recorded broadcast stopping instruction, stopping extracting the live broadcast video stream to obtain a target recorded broadcast video stream, generating a video file corresponding to the target recorded broadcast video stream, and performing associated storage on the video file and the article link locally.

These implementations may store the video file and the item link locally in association, so that a user of the terminal, such as an anchor, may choose to publish both at any time.
In some optional implementations of this embodiment, the locally performing associated storage on the video file and the item link in step 404 may include: adding an identifier to a video file; and associating the identifier with the item link, and locally storing the video file, the item link and the identifier in an associated manner.
In these alternative implementations, the execution body may add an identifier to the video file. The identification is used to distinguish the video file from other video files. And, the execution subject may further associate the identifier with an item link. In this way, if the user wants to publish the video file, the terminal can find the item link associated with the identifier, so that the video file and the item link are published together.
Optionally, the method may further include: in response to detecting a video publishing operation on the video file, extracting an item link associated with an identifier of the video file; and performing associated publishing on the video file and the extracted item link, wherein the shopping cart identifier associated with the extracted item link is presented in a video playing interface of the published video file.
Specifically, the executing agent may determine the identifier of the video file when a video distribution operation on the video file is detected. And extracts the item link with which the identification is associated. In this way, the execution agent may publish the item link and the video file together. In practice, the execution subject can upload the video file and the article link to the server, so that the server can realize the distribution of the video.
The execution subject can display the shopping cart identifier in the published video, so that the audience of the video can quickly purchase the articles by operating the shopping cart identifier, and a more quick article purchase channel is provided for the user. Specifically, the shopping cart identification corresponds to the item link. When a user watching the recorded video file clicks the shopping cart identifier, a purchase entry, such as the purchase entry including the item name, the item price and the "go to see" button, may be displayed in the video frame corresponding to the video file. If the user clicks the button, the displayed screen may jump to the purchase page for the item indicated by the item link. Alternatively, the user clicks on the purchase entry and the displayed screen may jump directly to the purchase page.
The optional implementation modes can extract the video file and the item link at any time when the user wants to publish the video, so that the video file and the item link can be published together.
In some optional cases, the publishing the video file and the item link may include: and performing associated publishing on the video file and the extracted item link so that the shopping cart identifier associated with the extracted item link appears in a video playing interface of the published video file.
