Some terms/nouns referred to in the embodiments of the present invention are explained below.
Frame rate: is a measure for measuring the number of frames, i.e. the number of frames in a unit of time.
Frame rate for screen refresh: the number of refresh frames of a picture displayed by a mobile terminal in a unit time is measured.
The screen recording frame rate is as follows: the method is used for measuring the frame number of the recorded screen of the picture displayed by the mobile terminal in unit time.
Screen recording: the method refers to a process that the mobile terminal encodes multi-frame pictures displayed on a screen and synthesizes videos according to the operation of a user. In the embodiment of the present invention, the screen recording specifically may be a process in which the mobile terminal continuously captures the screen of the picture displayed on the screen according to the trigger operation of the user, generates a bitmap, performs format conversion on the bitmap, and then synthesizes the bitmap after the format conversion into a video.
When a dynamic picture is displayed on a screen of the mobile terminal, if a user wants the mobile terminal to record the dynamic picture displayed on the screen of the mobile terminal, the user may trigger the mobile terminal to record the screen through one input (for example, the user may click a screen recording control on the currently displayed picture of the mobile terminal to trigger the mobile terminal to record the screen), so that, after the mobile terminal detects the input of the user, the mobile terminal may record the currently displayed dynamic picture in a screen recording manner.
Based on this, an embodiment of the present invention provides a method for adjusting a screen recording frame rate and a mobile terminal, which may acquire a first screen recording frame rate (where the first screen recording frame rate is a refresh frame rate of a currently displayed screen of the mobile terminal) and a first screen recording frame rate (where the first screen recording frame rate is a frame rate of the currently displayed screen of the mobile terminal), and when an absolute value of a first difference (where the first difference is a difference between the first screen recording frame rate and the first screen recording frame rate) is greater than or equal to a first preset threshold, adjust the first screen recording frame rate to a second screen recording frame rate (where an absolute value of a second difference is smaller than an absolute value of the first difference, and the second difference is a difference between the second screen recording frame rate and the first screen recording frame rate). According to the scheme, in the screen recording process of the mobile terminal, the frame rate of the screen recording of the currently displayed picture (namely the first screen recording frame rate) by the mobile terminal can be dynamically adjusted according to the refreshing frame rate of the currently displayed picture (namely the first screen recording frame rate), so that the adjusted screen recording frame rate (namely the second screen recording frame rate) of the mobile terminal is closer to the first picture refreshing frame rate, and therefore, the mobile terminal can reduce resources occupied by the screen recording as much as possible on the premise of ensuring the screen recording effect by flexibly adjusting the screen recording frame rate.
The mobile terminal in the embodiment of the present invention may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a Personal Digital Assistant (PDA), and the like, and the embodiment of the present invention is not limited specifically.
The execution main body of the screen recording frame rate adjustment method provided by the embodiment of the present invention may be the mobile terminal, or may also be a functional module and/or a functional entity capable of implementing the screen recording frame rate adjustment method in the mobile terminal, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a mobile terminal as an example to exemplarily describe the screen recording frame rate adjustment method provided by the embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for adjusting a frame rate of a video recording, where the method may include the following steps 10 to 11.
And step 10, the mobile terminal acquires a first picture refreshing frame rate and a first screen recording frame rate.
The first frame rate for refreshing the image is a frame rate for refreshing the image currently displayed by the mobile terminal, and the first frame rate for recording the image is a frame rate for recording the image currently displayed by the mobile terminal.
Optionally, in an embodiment of the present invention, a unit of the first screen refreshing frame rate and the first screen recording frame rate is a Frame Per Second (FPS). For example, the first screen refresh frame rate is 60FPS, and the first screen recording frame rate is 30 FPS.
For example, in the embodiment of the present invention, the first screen recording frame rate may be a frame rate for recording a screen of an operation screen currently displayed by the mobile terminal (for example, a courseware making screen and a Word editing screen), may also be a frame rate for recording a screen of a video screen currently displayed by the mobile terminal (for example, an online teaching screen, an online television screen, a video chat screen, and the like), and in an actual application, may also be a frame rate for recording a screen of any other screen currently displayed by the mobile terminal, which meets an actual use requirement.
Optionally, in the embodiment of the present invention, the first screen recording frame rate may be a screen recording frame rate when the mobile terminal records a display screen for the first time, or may be a screen recording frame rate after the mobile terminal adjusts the frame rate when the mobile terminal records the display screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Alternatively, in the embodiment of the present invention, the step 10 may be specifically implemented by a step 10a described below.
Step 10a, the mobile terminal obtains a first picture refreshing frame rate and a first screen recording frame rate according to a preset period.
The preset period may be determined according to a maximum refresh frame rate of a picture that can be displayed by the mobile terminal.
For example, assuming that the maximum refresh frame rate of a screen that can be displayed by the mobile terminal (hereinafter, referred to as the maximum screen refresh frame rate) is 60FPS, the refresh period of each frame of the screen corresponding to the maximum screen refresh frame rate is 16.67 ms. It is understood that, in the case that the preset period is greater than the refresh period of the picture per frame (i.e. 16.67ms described above), the number of frames refreshed by the mobile terminal within the preset period, which is acquired by the mobile terminal, is inaccurate, so that the mobile terminal may not accurately acquire the refresh frame rate of the picture currently displayed by the mobile terminal, and therefore, the preset period may be set to be less than or equal to 16.67 ms.
Optionally, the preset period may be any value in an interval of [4.17ms-16.67ms ].
Of course, it is understood that, in the embodiment of the present invention, the mobile terminal may also execute the screen recording frame rate adjusting method provided in the embodiment of the present invention when the mobile terminal displays each frame, for example, the mobile terminal executes the step 10 when the mobile terminal displays each frame.
And step 11, when the absolute value of the first difference is greater than or equal to a first preset threshold, the mobile terminal adjusts the first screen recording frame rate to a second screen recording frame rate.
Wherein, the first difference is a difference between the first screen recording frame rate and the first picture refreshing frame rate. In an embodiment of the present invention, an absolute value of a second difference is smaller than an absolute value of the first difference, and the second difference is a difference between the second frame recording rate and the first frame refreshing rate. That is to say, in the embodiment of the present invention, the second screen recording frame rate adjusted by the mobile terminal is closer to the first screen refreshing frame rate than the first screen recording frame rate.
It should be noted that, in the embodiment of the present invention, the first preset threshold may be determined according to parameters such as performance (e.g., processor performance) of a hardware platform of the mobile terminal and an acceptable level of power consumption of the mobile terminal, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, after the mobile terminal obtains the first image refresh frame rate and the first screen recording frame rate, the mobile terminal may first obtain an absolute value of a difference between the first image refresh frame rate and the first screen recording frame rate (that is, an absolute value of the first difference), then determine whether the absolute value of the first difference is greater than or equal to a first preset threshold, and when the absolute value of the first difference is greater than or equal to the first preset threshold, the mobile terminal may adjust the first screen recording frame rate to the second screen recording frame rate. Because the absolute value of the difference between the second screen recording frame rate and the first picture refreshing frame rate (i.e. the absolute value of the second difference) is smaller than the absolute value of the first difference, the adjusted second screen recording frame rate of the mobile terminal is closer to the first picture refreshing frame rate, so that resources occupied by screen recording can be reduced as much as possible on the premise of ensuring the screen recording effect.
For example, in an embodiment of the present invention, it is assumed that the first preset threshold may be 10FPS, the first screen recording frame rate is 30FPS, the first screen refresh frame rate is 60FPS, and the second screen recording frame rate is 35 FPS. The mobile terminal can acquire that the absolute value of the difference between the first image refresh frame rate and the first screen recording frame rate is 30FPS, and then can judge that the absolute value of the difference between the first image refresh frame rate and the first screen recording frame rate (namely, the 30FPS) is greater than a first preset threshold value (namely, the 10FPS), at this moment, the mobile terminal can adjust the first screen recording frame rate (namely, the 30FPS) to a second screen recording frame rate (namely, the 35FPS), so that the adjustment of the screen recording frame rate by the mobile terminal is realized.
For example, in an embodiment of the present invention, it is assumed that the first preset threshold may be 10FPS, the first screen recording frame rate is 40FPS, the first screen refreshing frame rate is 25FPS, and the second screen recording frame rate is 35 FPS. The mobile terminal may obtain that an absolute value of a difference between the first image refresh frame rate and the first screen recording frame rate is 15FPS, and then may determine that the absolute value of the difference between the first image refresh frame rate and the first screen recording frame rate (i.e., the 15FPS) is greater than a first preset threshold (i.e., the 10FPS), at this time, the mobile terminal may adjust the first screen recording frame rate (i.e., the 40FPS) to a second screen recording frame rate (i.e., the 35FPS), so that the adjustment of the screen recording frame rate by the mobile terminal is achieved.
In the method for adjusting the screen recording frame rate provided by the embodiment of the invention, in the screen recording process of the mobile terminal, the frame rate of the screen recording of the currently displayed picture (namely, the first screen recording frame rate) by the mobile terminal can be dynamically adjusted according to the refreshing frame rate of the currently displayed picture (namely, the first screen recording frame rate), so that the adjusted screen recording frame rate of the mobile terminal (namely, the second screen recording frame rate) is closer to the first screen refreshing frame rate, and therefore, the mobile terminal can reduce resources occupied by the screen recording as much as possible on the premise of ensuring the screen recording effect by flexibly adjusting the screen recording frame rate.
Optionally, with reference to fig. 1 and as shown in fig. 2, before the mobile terminal adjusts the first screen recording frame rate to the second screen recording frame rate in step 11, the method for adjusting the screen recording frame rate according to the embodiment of the present invention may further include step 12 as described below. Step 11 can be specifically realized by step 11a described below.
And step 12, when the absolute value of the first difference is greater than or equal to a first preset threshold, the mobile terminal acquires a second screen recording frame rate.
And 11a, the mobile terminal adjusts the first screen recording frame rate to a second screen recording frame rate.
In the embodiment of the present invention, after the mobile terminal obtains the second screen recording frame rate, the mobile terminal may adjust the first screen recording frame rate to the second screen recording frame rate.
Optionally, in the embodiment of the present invention, the step 12 may be specifically implemented by the following step 12a, step 12b, or step 12 c.
And step 12a, the mobile terminal increases or decreases a second preset threshold value to the first screen recording frame rate to obtain a second screen recording frame rate.
It should be noted that, in the embodiment of the present invention, the second preset threshold may be determined according to parameters such as performance (for example, processor performance) of a hardware platform of the mobile terminal and an acceptable degree of power consumption of the mobile terminal, and the embodiment of the present invention is not limited specifically.
Optionally, in an embodiment of the present invention, the second preset threshold may be any one of 3FPS, 4FPS, 5FPS, … …, and 10 FPS. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in an embodiment of the present invention, in a possible implementation manner, if the first screen recording frame rate is less than the first screen refreshing frame rate, and an absolute value of a difference between the first screen recording frame rate and the first screen refreshing frame rate is greater than or equal to a first preset threshold, the mobile terminal may increase a second preset threshold to the first screen recording frame rate to obtain a second screen recording frame rate.
In another possible implementation manner, if the first screen recording frame rate is greater than the first screen refreshing frame rate, and an absolute value of a difference between the first screen recording frame rate and the first screen refreshing frame rate is greater than or equal to a first preset threshold, the mobile terminal may decrease the first screen recording frame rate by a second preset threshold to obtain a second screen recording frame rate.
In the embodiment of the invention, when the absolute value of the difference value between the first screen recording frame rate and the first picture refreshing frame rate is greater than or equal to the first preset threshold, the mobile terminal increases or decreases the second preset threshold to the first screen recording frame rate, so that the mobile terminal can obtain the second screen recording frame rate, and the adjustment of the screen recording frame rate of the mobile terminal can be realized.
And step 12b, the mobile terminal acquires a second screen recording frame rate corresponding to the first image refreshing frame rate according to the first image refreshing frame rate and the first preset corresponding relation.
Wherein the first preset corresponding relationship is a corresponding relationship between the first frame refreshing rate and the second frame recording rate.
Optionally, in the method for adjusting a frame rate of a screen recording provided in the embodiment of the present invention, the mobile terminal may include a plurality of preset corresponding relationships, and each preset corresponding relationship may be a corresponding relationship between one screen refreshing frame rate and one screen recording frame rate. The first predetermined corresponding relationship is one of the predetermined corresponding relationships. Specifically, in actual implementation, which preset corresponding relationship is adopted may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
Illustratively, table 1 is a preset corresponding relationship table between the frame rate for refreshing the image and the frame rate for recording the image. As shown in table 1, assuming that the first frame rate is 40FPS, according to the preset mapping table, when the first frame rate is 40FPS, the second frame rate corresponding to the first frame rate is 20 FPS.
Table 1 preset correspondence table between frame refreshing rate and frame recording rate
| Frame rate for refreshing picture (Unit: FPS) | Recording screen frame rate (Unit: FPS) |
| 20 | 10 |
| 30 | 15 |
| 40 | 20 |
| 50 | 25 |
| 60 | 30 |
When the absolute value of the difference value between the first screen recording frame rate and the first picture refreshing frame rate is greater than or equal to a first preset threshold value, the mobile terminal can acquire a second screen recording frame rate corresponding to the first picture refreshing frame rate according to the first picture refreshing frame rate and the first preset corresponding relation, and therefore adjustment of the screen recording frame rate of the mobile terminal can be achieved.
And step 12c, the mobile terminal acquires a second screen recording frame rate corresponding to the first picture refreshing frame rate according to the first picture refreshing frame rate and a preset formula.
Wherein, the preset formula may be: a1 is k × S1, a1 indicates the second frame rate, S1 indicates the first frame rate, and k indicates a reference ratio between a preset frame rate and a preset frame rate.
It should be noted that, in the embodiment of the present invention, k in the preset formula may be determined according to parameters such as performance (e.g., processor performance) of a hardware platform of the mobile terminal and an acceptable level of power consumption of the mobile terminal, which is not limited in the embodiment of the present invention.
Optionally, an embodiment of the present invention provides a method for determining k in the preset formula, where the method includes the following steps a to e:
step a: the frame rate of frame refreshing is set to S.
Step b: and setting the screen recording frame rate corresponding to the picture refreshing frame rate S as K according to experience.
Step c: and acquiring the screen recording power consumption and the screen recording effect of the mobile terminal when the screen recording frame rate is K.
Step d: and adjusting the screen recording frame rate K according to the screen recording power consumption and the screen recording effect of the mobile terminal, and setting the adjusted screen recording frame rate A.
Step e: and d, repeatedly executing the step c and the step d until the screen recording power consumption and the screen recording effect of the mobile terminal meet the actual use requirements, and recording the picture refreshing frame rate and the screen recording frame rate corresponding to the picture refreshing frame rate at the moment. It is assumed that the frame rate of the recorded screen refresh is S, the frame rate of the screen recording is a, and k is a/S.
For example, assuming that the picture refresh frame rate value S is 60FPS, the screen recording frame rate value a is 30FPS, and the first picture refresh frame rate S1 is 50FPS, then k is equal to a/S equal to 30FPS/60FPS equal to 1/2, and the second screen recording frame rate a1 is:
A1＝k*S1＝1/2*50FPS＝25FPS。
in the embodiment of the invention, when the absolute value of the difference value between the first screen recording frame rate and the first picture refreshing frame rate is greater than or equal to the first preset threshold, the mobile terminal can acquire the second screen recording frame rate corresponding to the first picture refreshing frame rate according to the first picture refreshing frame rate and the preset formula, so that the adjustment of the screen recording frame rate of the mobile terminal can be realized.
Optionally, with reference to fig. 1, as shown in fig. 3, in the embodiment of the present invention, before step 10, the method for adjusting the frame rate for recording a screen according to the embodiment of the present invention may further include the following steps 13 to 16.
And step 13, the mobile terminal detects the input of the user.
And 14, under the condition that the mobile terminal detects the first input of the user, the mobile terminal acquires a second picture refreshing frame rate.
The first input may be used to trigger the mobile terminal to start recording a screen, and the second frame rate is a frame rate at which the mobile terminal detects the first input of the user.
Optionally, in this embodiment of the present invention, when the user triggers the mobile terminal, the mobile terminal may detect the first input of the user, and acquire the refresh frame rate of the picture displayed by the mobile terminal when the first input of the user is detected (that is, the refresh frame rate of the second picture).
Optionally, in this embodiment of the present invention, the first input may be a click or a slide operation of a screen recording control on a currently displayed screen of the mobile terminal by a user, may also be a click or a slide operation of a prompt message (which is used to prompt the user to trigger the mobile terminal to record a screen on the currently displayed screen) on the screen displayed by the mobile terminal by the user, and may also be a press operation of a physical key of the mobile terminal by the user (for example, the user may press a volume key and a power-off key of the mobile terminal at the same time to trigger the screen recording of the mobile terminal). The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
And step 15, the mobile terminal acquires a first screen recording frame rate corresponding to the second image refreshing frame rate according to the second image refreshing frame rate and a second preset corresponding relation.
Wherein the second preset corresponding relationship is a corresponding relationship between the second frame refreshing rate and the first frame recording rate.
Optionally, in this embodiment of the present invention, the mobile terminal may include a plurality of preset corresponding relationships, each preset corresponding relationship may be a corresponding relationship between one screen refresh frame rate and one screen recording frame rate, and the second preset corresponding relationship is one preset corresponding relationship among the plurality of preset corresponding relationships. For the description of the multiple preset correspondences, reference may be specifically made to the related description of step 12 in the foregoing embodiment, and details are not described here again.
For example, with reference to table 1, assuming that the second screen refresh frame rate is 50FPS, according to the preset correspondence table shown in table 1, when the second screen refresh frame rate is 50FPS, the first screen recording frame rate corresponding to the second screen refresh frame rate is 25 FPS.
And step 16, the mobile terminal records the screen according to the first screen recording frame rate.
It can be understood that, in the embodiment of the present invention, after the user triggers the mobile terminal to record the screen, before the mobile terminal starts to record the screen, the mobile terminal may first obtain a screen recording frame rate (i.e., a first screen recording frame rate) corresponding to a refresh frame rate of a picture currently displayed by the mobile terminal (i.e., a picture displayed by the mobile terminal when the mobile terminal detects a first input of the user), and then start to record the screen according to the first screen recording frame rate, that is, after the user triggers the mobile terminal to record the screen, the mobile terminal records the screen according to the first screen recording frame rate. And in the screen recording process, the mobile terminal dynamically adjusts the screen recording frame rate of the mobile terminal according to the refreshing frame rate of the picture displayed by the mobile terminal in real time.
Certainly, in the embodiment of the present invention, after the user triggers the mobile terminal to record the screen, the mobile terminal may also start to record the screen according to the default initial screen recording frame rate in the mobile terminal, and then during the screen recording process, the mobile terminal dynamically adjusts the screen recording frame rate of the mobile terminal according to the refresh frame rate of the picture displayed by the mobile terminal in real time.
According to the screen recording frame rate adjusting method provided by the embodiment of the invention, the mobile terminal can acquire the refresh frame rate (the second screen refresh frame rate) of the picture displayed by the mobile terminal when the first input of the user is detected according to the input (the first input) that the mobile terminal starts to record the screen detected by the user, and further acquire the first screen recording frame rate corresponding to the second screen refresh frame rate, so that after the user triggers the screen recording of the mobile terminal, the mobile terminal starts to record the screen according to the first screen recording frame rate corresponding to the second screen refresh frame rate, and therefore, the mobile terminal can reduce resources occupied by screen recording as much as possible on the premise of ensuring the screen recording effect by flexibly adjusting the screen recording frame rate.
Optionally, with reference to fig. 1, as shown in fig. 4, in the embodiment of the present invention, after step 11, the method for adjusting the frame rate for recording a screen according to the embodiment of the present invention may further include step 17 described below.
And step 17, the mobile terminal records the screen according to the second screen recording frame rate.
In the embodiment of the invention, after the mobile terminal adjusts the first screen recording frame rate to the second screen recording frame rate, the mobile terminal can record the screen according to the adjusted screen recording frame rate (namely the second screen recording frame rate), so that the mobile terminal can reduce the resources occupied by the screen recording as much as possible on the premise of ensuring the screen recording effect as the mobile terminal can flexibly adjust the screen recording frame rate.
It should be noted that, in the embodiment of the present invention, the mobile terminal may circularly execute the screen recording frame rate adjusting method provided in the embodiment of the present invention, so as to dynamically adjust the screen recording frame rate in the screen recording process of the mobile terminal. In the above embodiments, the method for adjusting the frame rate of the screen recording once executed by the mobile terminal is taken as an example for exemplary explanation, and in particular, for the description of the method for adjusting the frame rate of the screen recording executed by the mobile terminal cyclically, reference may be made to the related description in the above embodiments, and details are not described here again.
In the embodiment of the invention, the screen recording frame rate can be closer to the refreshing frame rate of the display picture of the mobile terminal by adjusting the screen recording frame rate by the mobile terminal, so that the mobile terminal records the screen according to the adjusted screen recording frame rate (namely the second screen recording frame rate), and resources occupied by screen recording can be reduced as much as possible on the premise of ensuring the screen recording effect.
Optionally, in this embodiment of the present invention, before the mobile terminal adjusts the first screen recording frame rate to the second screen recording frame rate in step 11, the method for adjusting the screen recording frame rate according to this embodiment of the present invention may further include step 18 described below.
And step 18, the mobile terminal judges whether the current electric quantity is greater than or equal to a preset electric quantity threshold value.
The preset electric quantity threshold value can be the preset minimum electric quantity capable of supporting the mobile terminal to record the screen of the current picture.
For example, if the current electric quantity of the mobile terminal is greater than or equal to the preset electric quantity threshold, the mobile terminal may continue to adjust the first screen recording frame rate to the second screen recording frame rate according to step 11; and if the current electric quantity of the mobile terminal is smaller than the preset electric quantity threshold value, the mobile terminal stops recording the current picture.
In the embodiment of the invention, before the mobile terminal adjusts the first screen recording frame rate, the mobile terminal judges whether the current mobile electric quantity can support the mobile terminal to record the screen of the current picture in advance, so that the problem that the mobile terminal cannot normally work due to continuous screen recording under the condition that the current mobile electric quantity of the mobile terminal is too low can be avoided, and the working stability of the mobile terminal can be ensured.
