All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In addition, the character "/" in the embodiment of the present application generally indicates that the preceding and following associated objects are in an "or" relationship.
Fig. 1 is a schematic flowchart of a screen recording method according to an embodiment of the present application, as shown in fig. 1.
101. Monitoring an application switching event of the terminal in a screen recording process of the terminal.
102. And setting mark information of the recorded video according to the monitored application switching event and the to-be-screen recording application of the terminal, so as to indicate the part of the recorded video related to the to-be-screen recording application.
103. And generating a screen recording file of the to-be-screen-recorded application according to the recorded video and the mark information of the recorded video.
It should be noted that part or all of the execution subjects of 101 to 103 may be an application located in the terminal, or may also be a functional unit such as a plug-in or Software Development Kit (SDK) set in the application located in the terminal, or may also be a processing engine located in a network side server, which is not particularly limited in this embodiment.
It is to be understood that the application may be a native app (native app) installed on the terminal, or may also be a web page program (webApp) of a browser on the terminal, which is not limited in this embodiment.
In this way, by monitoring the application switching event of the terminal during the screen recording process of the terminal, and further setting the mark information of the recorded video for indicating the part of the recorded video related to the application to be screen recorded according to the monitored application switching event and the application to be screen recorded of the terminal, so that the screen recording file of the application to be screen recorded can be generated according to the recorded video and the mark information of the recorded video, since the mark information indicating the part of the recorded video related to the application to be screen recorded is set during the screen recording process of the terminal, the part of the recorded video related to the application to be screen recorded is identified from the recorded video according to the mark information to synthesize the screen recording file of the application to be screen recorded, and the part irrelevant to the application to be screen recorded is filtered out, thereby effectively improving the reliability of screen recording.
In the present application, the application to be screen-recorded of the terminal that is to perform screen recording may be determined before the screen recording function is started, or the application to be screen-recorded of the terminal that is to perform screen recording may also be determined after the screen recording function is started, which is not particularly limited in the present application.
Optionally, in a possible implementation manner of this embodiment, the application to be screen-recorded may be determined specifically in response to an operation of the user based on the supported screen recording application list before the screen recording process of the terminal.
In this implementation, a list of applications that support screen recording, which may be referred to as a screen recording application list, may be provided to the user. The list may include all applications installed on the terminal, or may further include a part of applications installed on the terminal, which is not particularly limited in this embodiment.
According to the screen recording requirement, a user can select one corresponding application, two corresponding applications or a plurality of corresponding applications from the screen recording application list of the terminal to serve as the applications to be recorded on the screen of the terminal.
Therefore, the screen recording application of the terminal can be determined.
After the screen recording application to be processed of the terminal is determined, the screen recording function can be further started in response to the operation of the user based on the screen recording interface, so that the screen recording of the terminal is started.
Optionally, in a possible implementation manner of this embodiment, the application to be screen-recorded may be determined specifically in response to an operation of the user based on the application to be screen-recorded during the screen recording process of the terminal.
In the implementation manner, the screen recording function can be started in response to the operation of the user based on the screen recording interface so as to start the screen recording of the terminal. In the screen recording process of the terminal, a user can select one application from all applications installed on the terminal according to the screen recording requirement and start to operate the application as the application to be screen recorded of the terminal.
Therefore, the screen recording application of the terminal can be determined.
In the application, since the screen recording requirement of the user is generally to perform screen recording on one or two or more designated applications to be screen-recorded, if the terminal switches to operate other applications instead of the applications to be screen-recorded during the screen recording process, the recorded video is the content that the user does not want to record at all. Therefore, the application switching event of the terminal can be monitored, and whether the screen recording application is in screen recording or not can be found in time by monitoring that the screen recording application is switched to other applications or other applications are switched to the screen recording application.
In the application, in the screen recording process, if an application switching event is not monitored, a screen recording method in the prior art can be adopted, a frame image on a terminal screen is intercepted through an API (application programming interface) provided by an operating system according to a specified frequency, the intercepted frame image is stored on a terminal in a video form, only when the application switching event is monitored, 102 is executed, and when the intercepted frame image is stored on the terminal in the video form, mark information of a recorded video can be further set according to the monitored application switching event and a to-be-screen recording application of the terminal, and the mark information is stored.
Optionally, in a possible implementation manner of this embodiment, in 101, it may be specifically determined that an application switching event of the terminal is monitored by monitoring a specified monitored object.
In a specific implementation process, the running state of the to-be-screen recorded application may be monitored, and then, according to the monitored running state, it may be determined that the application switching event of the terminal is monitored.
The content recorded by the screen is the content displayed by the screen of the acquisition terminal, so that the relevant operation of the application to be screen-recorded can be acquired only when the running state of the application to be screen-recorded of the terminal is foreground running, and the relevant operation of the application to be screen-recorded cannot be acquired when the running state of the application to be screen-recorded of the terminal is background running. Therefore, by monitoring the running state of the to-be-screen recorded application, once the running state of the to-be-screen recorded application is monitored to change, namely the running is performed from the foreground to the background and from the background to the foreground, the application switching event of the terminal can be determined to be monitored.
In another specific implementation process, the screen recording interface of the terminal may be monitored, and then, the monitored application switching event of the terminal may be determined according to the monitored switching of the applications in the screen recording interface.
The content recorded by the screen is the content displayed in the screen recording interface of the acquisition terminal, so that the related operation of the application to be screen recorded can be acquired only when the application interface of the application to be screen recorded of the terminal appears in the screen recording interface of the terminal, and the related operation of the application to be screen recorded cannot be acquired when the application interface of the application to be screen recorded of the terminal does not appear in the screen recording interface of the terminal or other applications appear in the screen recording interface of the terminal. Therefore, by monitoring the screen recording interface of the terminal, once the application in the screen recording interface is monitored to be changed, namely the application to be recorded on the screen is changed into other applications, and the other applications are changed into the application to be recorded on the screen, the application switching event of the terminal can be determined to be monitored.
The application switching event may refer to a terminal operation event for switching from one application to another application, and the event may include, but is not limited to, an application identifier of one application before switching and an application identifier of another application after switching.
Optionally, in a possible implementation manner of this embodiment, in 102, as long as an application switching event is monitored, the mark information of the recorded video may be set according to the monitored application switching event and the application to be screen-recorded of the terminal.
At this time, because the mark information of the recorded video is set, a part of the recorded video related to the application of the screen recording to be performed can be indicated, and only this part of the content is the content which needs to be subjected to the screen recording and corresponds to the screen recording requirement of the user this time.
During the screen recording process, the user can switch the application of the terminal at will without any restriction. By adopting the technical scheme, any application switching performed by the user can be monitored and marked.
After the application switching event is monitored, the application switching event can be further determined to be an application switching event for switching from the application to be screen recorded to other applications or an application switching event for switching from other applications to the application to be screen recorded according to the monitored application switching event and the application to be screen recorded of the terminal, so that the mark information of the recorded video can be set.
In a specific implementation process, the marking information of the part of the recorded video related to the to-be-screen recording application may be specifically set according to the monitored application switching event and the to-be-screen recording application of the terminal.
For example, the start mark and/or the end mark of the part of the recorded video related to the application to be screen recorded may be specifically set according to the monitored application switching event and the application to be screen recorded of the terminal.
If the monitored application switching event is that the application to be screen recorded is switched to other applications, an end mark of a part of the recorded video, which is related to the application to be screen recorded, can be set at the current position in the recorded video, so as to indicate that the part of the recorded video, which is before the end mark, is the part related to the application to be screen recorded.
At this point, the part before the end mark in the recorded video can be determined as the part related to the to-be-screen-recorded application according to the end mark. If other marks are further set before the end mark, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with other marks. For example, a start mark of a portion of the recorded video related to the to-be-screen-recorded application is further set before the end mark, and then a portion between the start mark and the end mark in the recorded video may be determined as the portion related to the to-be-screen-recorded application according to the start mark and the end mark.
If the monitored application switching event is that other applications are switched to the application to be screen recorded, a start mark of a part of the recorded video related to the application to be screen recorded can be set at the current position in the recorded video, so as to indicate that the part of the recorded video after the start mark is the part related to the application to be screen recorded.
In this case, the part after the start mark in the recorded video may be determined as the part related to the to-be-screen-recorded application according to the start mark. If other marks are further set after the start mark, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with other marks. For example, after the start mark, an end mark of a portion of the recorded video related to the to-be-screen-recorded application is further set, and then, according to the start mark and the end mark, a portion between the start mark and the end mark in the recorded video may be determined as the portion related to the to-be-screen-recorded application.
Or, for another example, the start time and/or the end time of the part of the recorded video that is related to the application to be screen recorded may be recorded specifically according to the monitored application switching event and the application to be screen recorded of the terminal.
If the monitored application switching event is that the screen-waiting recording application is switched to other applications, the recording time from the current time to the recording start time can be recorded as the end time of the part of the recorded video related to the screen-waiting recording application, so as to indicate the part of the recorded video before the end time is the part related to the screen-waiting recording application.
In this case, the portion of the recorded video before the end time may be determined as the portion related to the to-be-screen-recorded application according to the end time. If other time is further recorded before the ending time, the specific range of the part related to the to-be-screen recorded application in the recorded video needs to be determined in further combination with other time. For example, before the end time, a start time of a portion of the recorded video related to the to-be-screen-recorded application is further recorded, and then, according to the start time and the end time, a portion between the start time and the end time in the recorded video may be determined as the portion related to the to-be-screen-recorded application.
If the monitored application switching event is that other applications are switched to the application to be screen recorded, the recording time from the current moment to the moment of starting recording can be recorded as the starting time of the part of the recorded video related to the application to be screen recorded, so as to indicate that the part of the recorded video after the starting time is the part related to the application to be screen recorded.
In this case, the part of the recorded video after the start time may be determined as the part related to the to-be-screen-recorded application according to the start time. If other times are further recorded after the start time, the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with the other times. For example, after the start time, an end time of a portion of the recorded video related to the to-be-screen-recorded application is further recorded, and then, according to the start time and the end time, a portion between the start time and the end time in the recorded video may be determined as the portion related to the to-be-screen-recorded application.
Or, for another example, the start frame number and/or the end frame number of the part of the recorded video that is related to the application to be screen recorded may be recorded specifically according to the monitored application switching event and the application to be screen recorded of the terminal.
If the monitored application switching event is that the application to be screen recorded is switched to other applications, the current frame number can be recorded as the end frame number of the part of the recorded video related to the application to be screen recorded, so as to indicate that the part of the recorded video before the end frame number is the part related to the application to be screen recorded.
At this point, the part before the ending frame number in the recorded video can be determined according to the ending frame number, and is the part related to the to-be-screen recording application. If other frame numbers are further recorded before the ending frame number, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with the other frame numbers. For example, before the ending frame number, a starting frame number of a part of the recorded video, which is related to the application for recording to be screen, is further recorded, then a part between the starting frame number and the ending frame number in the recorded video may be determined to be the part related to the application for recording to be screen according to the starting frame number and the ending frame number.
If the monitored application switching event is switching from other applications to the application to be screen recorded, the current frame number can be recorded as the starting frame number of the part of the recorded video related to the application to be screen recorded, so as to indicate that the part of the recorded video after the starting frame number is the part related to the application to be screen recorded.
At this point, the part after the starting frame number in the recorded video can be determined according to the starting frame number, and is the part related to the to-be-screen recording application. If other frame numbers are further recorded after the starting frame number, the specific range of the part related to the to-be-screen recorded application in the recorded video needs to be determined in further combination with the other frame numbers. For example, after the start frame number, an end frame number of a portion of the recorded video related to the recording application to be screen-recorded is further recorded, and then, according to the start frame number and the end frame number, a portion between the start frame number and the end frame number in the recorded video may be determined to be the portion related to the recording application to be screen-recorded.
In another specific implementation process, the marking information of the part of the recorded video that is not related to the application for screen recording may be specifically set according to the monitored application switching event and the application for screen recording of the terminal.
For example, the start flag and/or the end flag of a portion of the recorded video that is not related to the application for recording on the screen may be specifically set according to the monitored application switching event and the application for recording on the screen of the terminal.
If the monitored application switching event is that the application to be screen recorded is switched to other applications, a start mark of a part, which is not related to the application to be screen recorded, in the recorded video can be set at the current position in the recorded video, so as to indicate that a part, which is in front of the start mark, in the recorded video is the part related to the application to be screen recorded.
At this point, the portion before the start mark in the recorded video may be determined as the portion related to the to-be-screen-recorded application according to the start mark. If other marks are further set before the start mark, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with other marks. For example, an end mark of a portion of the recorded video that is not related to the to-be-screen-recorded application is further set before the start mark, and then a portion between the start mark and the end mark in the recorded video may be determined as a portion related to the to-be-screen-recorded application according to the end mark and the start mark.
If the monitored application switching event is that other applications are switched to the application to be screen recorded, an end mark of a part of the recorded video, which is not related to the application to be screen recorded, can be set at the current position in the recorded video, so as to indicate that a part of the recorded video, which is behind the end mark, is a part related to the application to be screen recorded.
At this point, the part after the end mark in the recorded video can be determined as the part related to the to-be-screen recording application according to the end mark. If other marks are further set after the end mark, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with other marks. For example, after the end mark, a start mark of a part of the recorded video that is not related to the to-be-screen-recorded application is further set, and then a part between the start mark and the end mark in the recorded video may be determined to be a part related to the to-be-screen-recorded application according to the end mark and the start mark.
Or, for another example, the start time and/or the end time of a part of the recorded video that is not related to the application for recording on the screen may be recorded specifically according to the monitored application switching event and the application for recording on the screen of the terminal.
If the monitored application switching event is that the application to be screen recorded is switched to other applications, the recording time from the current time to the time of starting recording can be recorded as the starting time of the part, irrelevant to the application to be screen recorded, of the recorded video, so as to indicate that the part, before the starting time, of the recorded video is the part, relevant to the application to be screen recorded.
In this case, the portion of the recorded video before the start time may be determined as the portion related to the to-be-screen-recorded application according to the start time. If other time is further recorded before the start time, the specific range of the part related to the to-be-screen recorded application in the recorded video needs to be determined in further combination with other time. For example, before the start time, an end time of a part of the recorded video that is not related to the to-be-screen recorded application is further recorded, and then a part between the end time and the start time in the recorded video may be determined as a part related to the to-be-screen recorded application according to the end time and the start time.
If the monitored application switching event is switching from other applications to the application to be screen-recorded, the recording time from the current time to the time of starting recording can be recorded as the end time of the part of the recorded video which is irrelevant to the application to be screen-recorded, so as to indicate that the part of the recorded video after the end time is the part relevant to the application to be screen-recorded.
In this case, the portion of the recorded video after the ending time may be determined as the portion related to the to-be-screen-recorded application according to the ending time. If other time is further recorded after the ending time, the specific range of the part related to the to-be-screen recorded application in the recorded video needs to be determined in further combination with other time. For example, after the end time, a start time of a portion of the recorded video that is not related to the to-be-screen-recorded application is further recorded, and then a portion between the end time and the start time in the recorded video may be determined as the portion related to the to-be-screen-recorded application according to the end time and the start time.
Or, for another example, the start frame number and/or the end frame number of the part of the recorded video that is not related to the application for recording on the screen may be recorded specifically according to the monitored application switching event and the application for recording on the screen of the terminal.
If the monitored application switching event is that the screen-waiting recording application is switched to other applications, the current frame number can be recorded as the starting frame number of the part of the recorded video which is irrelevant to the screen-waiting recording application, so as to indicate that the part before the starting frame number in the recorded video is the part relevant to the screen-waiting recording application.
At this point, the part before the start frame number in the recorded video can be determined as the part related to the to-be-screen recording application according to the start frame number. If other frame numbers are further recorded before the starting frame number, then the specific range of the part related to the to-be-screen-recorded application in the recorded video needs to be determined in further combination with the other frame numbers. For example, before the start frame number, an end frame number of a part of the recorded video that is not related to the to-be-screen recorded application is further recorded, and then a part between the end frame number and the start frame number in the recorded video may be determined as a part related to the to-be-screen recorded application according to the end frame number and the start frame number.
If the monitored application switching event is switching from other applications to the application to be screen recorded, the current frame number may be recorded as an end frame number of a part of the recorded video that is not related to the application to be screen recorded, so as to indicate that a part of the recorded video that follows the end frame number is a part related to the application to be screen recorded.
At this point, the part after the ending frame number in the recorded video can be determined according to the ending frame number, and is the part related to the to-be-screen recording application. If other frame numbers are further recorded after the ending frame number, the specific range of the part related to the to-be-screen-recorded application in the recorded video is further determined in combination with the other frame numbers. For example, after the ending frame number, a starting frame number of a part of the recorded video, which is not related to the to-be-screen recorded application, is further recorded, then a part between the ending frame number and the starting frame number in the recorded video may be determined to be a part related to the to-be-screen recorded application according to the ending frame number and the starting frame number.
It can be understood that, the above two technical solutions in the implementation processes may be further combined to set the mark information of the recorded video.
Therefore, by monitoring that the application for recording the screen to be recorded is switched to other applications, or other applications are switched to the application for recording the screen to be recorded, whether the application for recording the screen to be recorded is screen-recorded or not can be timely found, and meanwhile, the setting of the marking information of the recorded video is carried out, so that the part, related to the application for recording the screen to be recorded, or the part, not related to the application for recording the screen, in the recorded video is marked, and therefore the part, related to the application for recording the screen, in the recorded video is indicated.
After the content that the user wants to perform screen recording is recorded, the screen recording function may be further turned off in response to an operation of the user based on the screen recording interface, so as to terminate the screen recording of the terminal.
In the application, after the screen recording is completed, the recorded video and the marking information of the video can be further stored.
Specifically, the recorded video and the mark information of the video may be stored in a storage device of the terminal.
In a specific implementation process, the storage device of the terminal may be a slow storage device, specifically, a hard disk of a computer system, or may also be a non-operating Memory of a mobile phone, that is, a physical Memory, such as a Read-Only Memory (ROM), a Memory card, and the like, which is not limited in this embodiment.
In another specific implementation process, the storage device of the terminal may also be a fast storage device, specifically, a Memory of a computer system, or may also be an operating Memory of a mobile phone, that is, a system Memory, for example, a Random Access Memory (RAM), and the like, which is not limited in this embodiment.
Optionally, in a possible implementation manner of this embodiment, in 103, the recorded video may be specifically subjected to a segmentation process according to the mark information of the recorded video to obtain a portion related to the to-be-screen recording application, and then, the obtained portion related to the to-be-screen recording application may be subjected to a synthesis process to obtain a screen recording file of the to-be-screen recording application.
In this implementation manner, after the screen recording is completed, all recorded videos and the mark information thereof may be further acquired, and the recorded videos are identified according to the mark information, and then may be subjected to subsequent processing according to the identification result of the identification processing.
Specifically, the recorded video may be segmented according to the mark information of the recorded video.
At this time, the recorded video may be divided into a plurality of segments, and the content corresponding to each segment may be determined as a part related to the application to be screen-recorded or a part unrelated to the application to be screen-recorded according to the mark information corresponding to the segment.
