In order that the aspects shown in the embodiments of the present application can be easily understood, several terms appearing in the embodiments of the present application will be explained below.
Target storage allowance: refers to the remaining capacity of the target storage space, may refer to the data storage capacity of the storage medium, and is a constant with a certain unit. For example, 1.34GByte, 529MByte or 800 Kbyte.
Target storage space: is a storage space for storing data generated by screen recording. In the scheme provided by the embodiment of the application, the terminal acquires the picture displayed in the terminal screen in the screen recording process, namely, data for storing the acquired picture is generated in the screen recording process, and the storage space for storing the data is the target storage space.
Alternatively, the target storage space may be a storage space of a storage medium on a terminal performing screen recording, including but not limited to an internal memory and an external memory of the terminal.
Alternatively, the target storage space may also be a storage space provided by a plurality of storage devices connected to the terminal for screen recording, where the storage devices include, but are not limited to, other terminals, lan hosts, workstations or storage servers, and the like.
The first screen recording parameter is as follows: may include at least one of resolution, coding format, code rate, and frame rate. The parameter may be one of a resolution, a coding format, a code rate or a frame rate, or may be a set of parameters including at least two of a resolution, a coding format, a code rate and a frame rate. The parameter is used when the terminal records the screen. Optionally, the parameter may be a parameter that is not changeable by a user and is built in the terminal, or a parameter that is provided by the terminal for the user to set. When a parameter is a non-modifiable parameter, neither the data type nor the value of the parameter may be modified.
And a second screen recording parameter: similar to the first screen recording parameter, at least one of resolution, encoding format, code rate and frame rate is also possible. The parameter may be one of a resolution, a coding format, a code rate or a frame rate, or may be a set of parameters including at least two of a resolution, a coding format, a code rate and a frame rate. And also for use when the terminal performs screen recording. Compared with the first screen recording parameter, the data volume generated by screen recording according to the second screen recording parameter in unit time of the terminal is smaller than the data volume generated by screen recording according to the first screen recording parameter. Optionally, the second screen recording parameter may be a parameter that is not changeable by a user and is built in the terminal, or a parameter that is provided by the terminal for the user to perform autonomous setting.
An information output component: the information can be perceived by a user through visual information, auditory information or somatosensory information, and the information comprises at least one of a screen, a loudspeaker, a vibration component, a prompt lamp and other components.
Illustratively, the screen recording method disclosed by the embodiment of the application can be applied to a terminal, and the terminal has a display screen and a screen recording function. The terminal may include a mobile phone, a tablet computer, a laptop computer, a desktop computer, a computer all-in-one machine, a server, a workstation, a television, a set-top box, smart glasses, a smart watch, a digital camera, an MP4 player terminal, an MP5 player terminal, a learning machine, a point-and-read machine, an electronic book, an electronic dictionary, a vehicle-mounted terminal, a Virtual Reality (VR) player terminal, an Augmented Reality (AR) player terminal, or the like.
Optionally, the function of the terminal to record the screen may be implemented by at least one of an operating system having a screen recording process, an application program having a screen recording function, or an application program capable of running a screen recording process.
(1) When the terminal realizes the screen recording function through an operating system with a screen recording process, the screen recording process can be a system process carried by the operating system, and the system process can display a corresponding screen recording control in a notification bar or a screen floating window of the terminal. The user controls the screen recording to start, pause, end and other operations by controlling the screen recording control.
(2) When the terminal realizes the screen recording function through the application program with the screen recording function, the application program can be a third-party application program installed under the operation of a user or an application program carried by the terminal when the terminal leaves a factory. When the application program is running, it is provided with a screen recording function so that the terminal can record a screen.
(3) When the terminal realizes the screen recording function through an application program capable of running the screen recording process, the screen recording process can be executed through a plug-in or a control. For example, an application may not have screen recording functionality originally, but may run a screen recording plug-in or screen recording control. And when the screen recording plug-in or screen recording control is installed in the application program, the terminal can record the screen when the screen recording plug-in or screen recording control is operated. For example, an application program a runs in the terminal, and the application program a does not have a screen recording function originally, and when the screen recording process a is downloaded by the terminal and the screen recording process a is run by the screen recording application a, the terminal can record a screen.
Please refer to fig. 1, which is a flowchart illustrating a screen recording method according to an exemplary embodiment of the present application. The screen recording method can be applied to the terminal shown above. In fig. 1, the screen recording method includes:
and step 110, recording the screen according to the first screen recording parameter.
In the embodiment of the application, the terminal has a screen recording function and can record the screen according to the first screen recording parameter. When recording the screen, the terminal firstly acquires the pictures displayed in the screen within each unit time. Herein, a picture within a unit time may be referred to as a frame picture. After the terminal acquires each frame of picture, the terminal can encode each frame of picture to obtain a corresponding screen recording file. The screen recording file is a file that can be played by a video player.
And step 120, monitoring a target storage allowance, wherein the target storage allowance is the residual capacity of a target storage space, and the target storage space is used for storing screen recording data.
Taking the terminal as a mobile phone as an example, when the mobile phone records the screen according to the first screen recording parameter, the mobile phone stores the monitoring target for the margin. Alternatively, when the target storage space is the storage space designated in the mobile phone, the terminal will call the relevant function to determine the remaining capacity of the designated storage space.
For example, the operating system hosted in the terminal is an Android operating system, and when the target storage space is a memory card, the terminal may call a getavailallesize () function to determine the storage capacity remaining in the memory card. When the target storage space is the internal storage of the mobile phone, the terminal may determine the storage capacity remaining in the internal storage by reading the data in the configuration file (e.g., "/proc/meminfo").
For another example, the operating system installed in the terminal is an iOS operating system, and when the target storage space is an external storage, the terminal may call a getAvailableDiskSize () function to determine the remaining capacity of the external storage. When the target storage space is the internal storage of the mobile phone, the terminal may determine the remaining capacity of the internal storage by calling the getavailablememorsize () function.
Optionally, if the target storage space includes storage spaces of at least two different storage spaces, the terminal sums the acquired remaining capacities of the at least two storage spaces, and determines the sum as the target storage remaining capacity.
The screen recording data generated by the terminal during screen recording can be stored in a temporary file, and the temporary file is temporarily stored in the target storage space during screen recording of the terminal. And after the screen recording process is finished, the terminal processes the temporary file to obtain a screen recording file which can be played by the player. The screen recording file stores multimedia data generated by screen recording of the terminal. Alternatively, the multimedia data may be at least one of video data, audio data, text data, and the like. For example, the temporary file may be a file with a suffix name of. avw, which may be converted into a screen-recording file with a suffix name of.avi after being processed by the terminal.
And step 130, when the target storage allowance is not larger than a preset threshold value, acquiring a second screen recording parameter.
In the embodiment of the application, the terminal acquires the second screen recording parameter when the target storage allowance is determined to be smaller than or equal to the preset threshold. It should be noted that the terminal may monitor the target storage margin in a periodic manner. Therefore, in a possible implementation manner, the terminal may acquire that the target storage allowance in one monitoring period is greater than the preset threshold, and acquire that the target storage allowance in the next adjacent monitoring period is less than the preset threshold. In another possible implementation, the target storage margin that the terminal may directly monitor is equal to the preset threshold. In the two possible implementation manners, the terminal acquires the second screen recording parameter.
And the screen recording data volume generated according to the second screen recording parameter is smaller than the screen recording data volume generated according to the first screen recording parameter in unit time. For example, the first screen recording parameter includes a resolution of 1080p and a frame rate of 30fps, and the second screen recording parameter may be a parameter whose resolution is less than 1080p and whose frame rate is maintained at 30fps, or the second screen recording parameter may also be a parameter whose resolution is 1080p and whose frame rate is less than 30fps, or the second screen recording parameter may also be a parameter whose resolution is less than 1080p and whose frame rate is less than 30 fps. It should be noted that, in the embodiment of the present application, the type and the value of the parameter specifically included in the first screen recording parameter and the second screen recording parameter are not limited.
Alternatively, the preset threshold may be a storage capacity set by an operating system of the terminal or an application program with a screen recording function. In some possible implementations, the preset threshold may be modified by a user.
And 140, recording the screen according to the second screen recording parameter.
In the embodiment of the application, after the terminal acquires the second screen recording parameter, the screen is recorded according to the second screen recording parameter. And storing screen recording data generated by recording the screen according to the second screen recording parameter.
In a possible implementation manner, screen recording data generated by screen recording according to the first screen recording parameter by the terminal can be processed together with screen recording data generated by screen recording according to the second screen recording parameter, and the processed screen recording data are spliced into a screen recording file. The screen recording file comprises a multimedia file segment recorded according to the first screen recording parameter and a multimedia file segment recorded according to the second screen recording parameter. When the screen recording file needs to be played, the terminal can directly play the screen recording file through the player.
In another possible implementation manner, screen recording data generated by screen recording according to the first screen recording parameter and data generated by screen recording according to the second screen recording parameter are respectively processed by the terminal to generate respective corresponding screen recording files. The screen recording file generated by screen recording according to the first screen recording parameter contains an identifier pointing to the screen recording file generated by screen recording according to the second screen recording parameter. In practical application, after the screen recording file generated by screen recording according to the first screen recording parameter is played, the player automatically acquires a file path of the screen recording file generated by screen recording according to the second screen recording parameter according to the identifier, and plays the screen recording file, so that a user can see complete screen recording content.
In summary, in the screen recording method provided in this embodiment, a screen is recorded according to the first screen recording parameter, the target storage allowance is monitored, when the target storage allowance is not greater than the preset threshold, the second screen recording parameter is obtained, and a screen is recorded according to the second screen recording parameter. The screen recording method provided by the embodiment of the application can obtain longer screen recording time under the condition that the target storage allowance is the same, and the success rate of long-time screen recording is improved.
Unlike the previous embodiment, the terminal is also capable of determining corresponding screen recording parameters for the recorded application, please refer to the following embodiment.
Please refer to fig. 2, which is a flowchart illustrating a screen recording method according to another exemplary embodiment of the present application. The screen recording method can be applied to the terminal shown above. In fig. 2, the screen recording method includes:
and step 201, starting to record the screen according to a screen recording starting instruction.
In the embodiment of the application, the terminal can start to record the screen according to the screen recording starting instruction. Wherein, the screen recording starting instruction can be realized as at least one of the following instructions.
(1) When the screen recording control is provided in the process or the application program for screen recording, the screen recording starting instruction may be an instruction generated when the user clicks the screen recording control for instructing to start screen recording.
(2) When the screen recording function is started in a mode of shaking the terminal or changing the posture of the terminal in the process or the application program for recording the screen, the terminal can acquire designated data through sensors such as a speed sensor, an acceleration sensor or a gyroscope. The screen recording start instruction may be an instruction generated based on specified data.
(3) When the screen recording function is started by receiving a voice instruction in a process or an application program for recording the screen, the terminal can collect the sound matched with the preset voice template. The screen recording starting instruction can be an instruction generated according to the sound matched with the preset voice template.
(4) When the process or the application program for recording the screen starts the screen recording function by receiving the touch signal, the terminal may acquire a designated touch signal, such as a short-press touch signal, a long-press touch signal, a light-press touch signal, a heavy-press touch signal, a sliding touch signal, or a multi-point touch signal. Optionally, for a terminal capable of distinguishing a knuckle touch signal, a palm touch signal, and a back-of-hand touch signal, the terminal may further collect signals such as the knuckle touch signal, the palm touch signal, or the back-of-hand touch signal. Alternatively, for a terminal capable of recognizing a Floating Touch (Floating Touch) signal, the terminal may also collect the Floating Touch signal. Optionally, for a folding screen terminal (including but not limited to an outer folding screen terminal and an inner folding screen terminal), the terminal may further collect a signal indicating that a folding angle of the folding screen is changed, for example, a signal generated when the folding screen of the folding screen terminal is changed from an unfolded state to a folded state. Alternatively, for a full-screen terminal, the terminal may collect specific data collected by the thermal sensor and/or the optical sensor, and the specific data indicates that the finger of the user performs a specified touch action in a specified area. The screen recording starting instruction is an instruction generated according to the signal acquired by the terminal.
(5) When the screen recording function is started through image recognition in the process or the application program for recording the screen, the terminal can acquire gestures, postures or expressions made by the user through the camera. The screen recording starting instruction can be an instruction generated after recognition according to at least one image in a designated gesture, posture or expression and the like.
In the embodiment of the application, the terminal can acquire the identifier of the first application program running in the foreground. If the operating system installed in the terminal is an android operating system, the terminal may determine the first application running in the foreground by obtaining an identifier of activity at the top of an activity stack (activity). Wherein the identifier of the activity is an identifier of the first application program.
In this embodiment of the application, the terminal may determine the first screen recording parameter according to the identifier of the first application. Please refer to fig. 3, which is an interface diagram of a screen recording provided based on the screen recording method shown in fig. 2. In fig. 3, the terminal is recording the screen, and a floating window 31 is displayed in the user interface in the screen, and the currently recorded duration (24 seconds) is displayed in the floating window 31. The terminal determines the identity of the application to which the user interface 32 belongs, which may be the name of the application or the name of the installation package of the application.
Optionally, the terminal is preset with two types of identifiers of the application program, one type of identifier corresponds to the high-quality image recording parameter, and the other type of identifier corresponds to the low-quality image recording parameter. And the terminal determines the corresponding screen recording parameters according to the identification of the application program. And if the application program is identified to be a slide show application program, an image-text editing application program, an image-text display application program or a video editing application program and the like, the terminal determines the low-image quality screen recording parameter as a first screen recording parameter. If the application program is identified to be a game application program, a video playing application program or a live broadcast application program, and the like, the terminal determines the high-image-quality screen recording parameter as a first screen recording parameter. In an application scenario, the terminal may preset a low-quality image capture parameter and a high-quality image capture parameter, wherein values of the two parameters may be as shown in table one.
Watch 1
| Parameter(s) | Resolution ratio | Coding format | Code rate | Frame rate |
| Low picture quality recording screen parameter | 480p | H.264 | 512Kbps | 24fps |
| High picture quality recording screen parameter | 1080p | H.264 | 2048Kbps | 30fps |
Optionally, besides the identifier of the application corresponding to the user interface displayed when the mobile phone terminal determines to record the screen as shown in fig. 3, the screen of the terminal may also display the user interfaces of multiple applications (for example, the terminal is a device such as a laptop, a desktop, or a computer all-in-one). When a plurality of application user interfaces are displayed in a screen of the terminal, the terminal can respectively determine application programs for displaying the user interfaces in the screen, and respectively acquire corresponding first screen recording parameters according to the application programs for displaying the user interfaces.
For example, when the terminal is a mobile phone, the interface displayed when the terminal records the screen is as shown in fig. 3. The name of the application program corresponding to the user interface 32 is "drawing assistant", and the name of the installation package is "huituxiaozhushou. In the embodiment of the application, the identifier corresponding to the application program can be generated in advance. For example, the terminal may determine that the identifier corresponding to the application is an image-text editing application identifier according to a "small drawing assistant" or a "huituxiaozhushou. Because the image-text editing application program has low requirements on image quality, the terminal can determine the first screen recording parameter according to the low-image-quality screen recording parameter.
For another example, when the terminal is a desktop computer, the desktop computer simultaneously displays a window of a live sports game player a, a window of an instant messaging application B and a window of a web browser C during screen recording. The desktop computer can respectively acquire respective identifiers of a live game player A, an instant messaging application program B and a web browser C, and respectively determine respective corresponding first screen recording parameters according to the three identifiers. At this time, the terminal can respectively determine the first screen recording parameters corresponding to the three windows according to the three identifiers, so that the watching effect of the screen recording file generated by the screen recording is ensured. For example, the window of live game player a uses a resolution of 720p, and the windows of instant messenger application B and web browser C use a resolution of 240 p.
And 204, recording the screen according to the first screen recording parameter.
The execution process of step 204 is the same as the execution process of step 110, and is not described here again.
And step 205, monitoring a target storage allowance, wherein the target storage allowance is the residual capacity of a target storage space, and the target storage space is used for storing screen recording data.
The execution process of step 205 is the same as the execution process of step 120, and is not described herein again.
As an alternative implementation, step 205 may be replaced by the following steps 1), 2) and 3) to implement the function of monitoring the target storage margin.
Step 1) determining a storage space for storing a screen recording file, wherein the screen recording file is a file generated according to screen recording data.
For a screen recording file, a storage space for storing the screen recording file is usually specified by an operating system of the terminal or an application program with a screen recording function. For example, the operating system in the mobile phone designates the storage space for storing the screen recording file in the data card.
And step 2) determining the residual storage capacity of the storage space and the specified residual capacity of the screen recording file, wherein the specified residual capacity is equal to the maximum storage capacity allowed to be occupied by the screen recording file minus the storage capacity occupied by the screen recording file.
In the embodiment of the application, the terminal determines the residual storage capacity of the storage space and the specified residual capacity of the screen recording file. It should be noted that the specified remaining capacity is equal to the maximum storage capacity allowed to be occupied by the screen recording file minus the storage capacity already occupied by the screen recording file.
For example, the maximum storage capacity allowed to be occupied by the screen recording file in the terminal is 200MByte, the storage space for storing the screen recording file is the memory card, and the screen recording file occupies the storage capacity of 80MByte at present, so that the specified remaining capacity is determined to be 120 MByte.
And 3) determining the smaller value of the residual storage capacity and the specified residual capacity of the screen recording file as the target storage allowance.
Based on the example of step 2), when the remaining storage capacity of the memory card is 350MByte, the terminal compares the 350MByte with the specified size of 120MByte, and determines the smaller 120MByte of the two as the target storage remaining capacity.
It should be noted that, after the execution of step 205 is completed, the terminal may execute step 2061, step 2062, and step 208, or execute step 2071, step 2072, and step 208.
In the embodiment of the application, when the target storage allowance is not larger than the preset threshold, the terminal queries the corresponding relation between the preset threshold and the second screen recording parameter from the terminal. The correspondence may be a correspondence table, or other data indicating the correspondence. For example, please refer to table two, which shows a corresponding relationship between a preset threshold and a second screen recording parameter.
Watch two
| Preset threshold (MByte) | 100 | 300 | 500 |
| Second recording screen parameter | Resolution 480p | Resolution 720p | Resolution 1080p |
In table two, the second screen recording parameter is illustrated as a single parameter (resolution), and when the preset threshold is 100MByte, 300MByte or 500MByte respectively, the value of the corresponding second screen recording parameter is correspondingly determined.
Step 2062, determining a second screen recording parameter corresponding to the preset threshold according to the corresponding relation.
In this embodiment of the application, when the target storage allowance is not greater than the preset threshold, the terminal may determine an identifier of the second application program running in the foreground. The terminal can use the system tool of its operating system hosted to obtain the identity of the second application.
In the embodiment of the application, when the identifier of the second application program is matched with the preset identifier, the terminal acquires the second screen recording parameter. The preset identifier may be an identifier preset by an operating system of the terminal or an application program with a screen recording function. The preset identifier may include at least one of the following identifiers: a social communication application identifier, a web browser identifier, a text editing application identifier, a text presentation application identifier, a video editing application identifier, an audio editing application identifier, a photographing application identifier, a map navigation application identifier, a security antivirus application identifier, or a financial payment application identifier, etc.
It should be noted that the preset identifier in the embodiment of the present application corresponds to an application program that does not have a high requirement on the image quality of a video recorded on a screen. Therefore, when the terminal determines that the identifier of the second application program is matched with the preset identifier, the terminal can acquire the second screen recording parameter.
Alternatively, as an alternative to step 2072, when the identifier of the application program does not match the preset identifier, the terminal may keep recording the screen using the first screen recording parameter. For example, if the identifier of the application is a game application identifier, a video playing application identifier, a live application identifier, or a short video playing application identifier, the terminal may keep recording the screen using the first screen recording parameter.
And step 208, recording the screen according to the second screen recording parameter.
And after the terminal determines the second screen recording parameter, the terminal records the screen according to the second screen recording parameter.

Different from the foregoing embodiments, the present application further provides a screen recording method, which enables a user to know that a terminal changes a screen recording parameter while prolonging a screen recording time, and please refer to the following embodiments.
Fig. 4 is a flowchart of a part of steps provided based on the screen recording method shown in fig. 2, and in fig. 4, after the terminal performs step 205, it may perform a first flow including step 2061 and step 2062, or may perform a second flow including step 2071 and step 2072. While the terminal performs the process one or the process two, the terminal may simultaneously perform the process three including the step 2091, the step 2092 and the step 2094. Alternatively, after completing step 205, the terminal may directly perform a fourth process including step 2091, step 2092 and step 2093. The execution process of steps 2091 to 2094 is as follows:
In the embodiment of the application, when the target storage allowance is not greater than the preset threshold, the terminal can display the reminding information through the information output component of the terminal, wherein the reminding information is used for reminding a user that the target storage allowance is not greater than the preset threshold. It should be noted that the display mode of the reminding information can be determined according to the form of the information output component. For example, if the information output component includes a screen, the display mode of the reminder information may be image display, and specifically may be text information, picture information, or animation information. If the information output component comprises a loudspeaker, the display mode of the reminding information can be voice reminding or ringing reminding. If the information output component comprises a prompting lamp, the display mode of the prompting information can be a light-emitting mode of the prompting lamp, such as normal lighting, flickering or color changing.
In a possible implementation display mode of the reminding information, the terminal is a mobile phone, and the information output component is a screen. Please refer to fig. 5, which is an interface diagram for displaying the reminding information provided based on the screen recording method shown in fig. 2. In fig. 5, when the terminal monitors that the target storage allowance is not greater than the preset threshold, the terminal displays a popup window 33 in the screen, and a prompt text "storage capacity is insufficient, and a low-capacity screen recording mode is performed after 3 seconds" is displayed in the popup window 33. In this case, the user can know the information that the storage capacity of the terminal is insufficient through the popup.
The terminal monitors whether a preset operation is received or not from the moment when the reminding information starts to be displayed, and sets a timer, wherein the preset operation is any one of operation of stopping screen recording, suspending screen recording or recording a screen by using a first screen recording parameter. Still taking the scenario shown in fig. 5 as an example, after the user sees the interface shown in fig. 5, the user may stop recording the screen or pause recording the screen. If the user wishes to stop recording the screen, the user may click on stop button 311, and if the user wishes to pause recording the screen, the user may click on pause button 312. Alternatively, the user still wishes to record the screen with the first screen recording parameter, the user may click the reject button 331.
At step 2093, if the timer is not over time and a preset operation is received, the display of the reminding information is stopped.
In the embodiment of the application, the terminal may stop displaying the reminding information when receiving the user operation within the timeout period of the timer. For example, when the timeout duration is 3 seconds, when the terminal starts monitoring the preset operation at the time 09:49 when the reminding message starts to be displayed, and if the preset operation is received before 09:52, the displaying of the reminding message is stopped. For example, hide a text pop-up box, stop a ring alert, stop a vibration, or stop an alert light from illuminating.
At step 2094, if the timer is over time, the display of the reminder information is stopped.
In the embodiment of the application, if the timer is overtime, the terminal stops displaying the reminding message after the duration of displaying the reminding message is equal to the overtime of the timer. For example, please refer to fig. 6, which is a schematic interface diagram provided based on the screen recording method shown in fig. 2. Fig. 6 may be an interface displayed after the terminal does not monitor the preset operation within the timeout period of the timer. In fig. 6, a notification window 34 is displayed in the user interface of the terminal, and the notification window is used to notify the user that the terminal records the screen according to the second screen recording parameter, for example, "the screen recording quality has been switched from 720p to 480 p" displayed in the notification window 34, which indicates that the terminal has entered the low-capacity screen recording mode.
In summary, according to the screen recording method provided by this embodiment, when the target storage allowance is not greater than the preset threshold, the information output component of the terminal displays the reminding information, and from the time when the reminding information starts to be displayed, whether the preset operation is received is monitored, and a timer is set, and if the timer is not overtime and receives the preset operation, or if the timer is overtime, the display of the reminding information is stopped. When the user can be reminded that the target storage allowance is not larger than the preset threshold value, the interference to the user is avoided, and the working efficiency of the user using the terminal is improved.
