Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, a flowchart of a first video recording method provided in an embodiment of the present invention is shown, where the method is applied to an electronic device, and the method may include:
In the embodiment of the present invention, before recording a screen of a target application in an electronic device of a user, the user needs to set a video length that the target application needs to record, that is, the user inputs a target duration. The target duration may also be automatically determined according to the type of the target application, and specifically, according to the content of different target applications, a corresponding default target duration may be preset, for example, the duration of a round of game in the application of the game type is about 10 to 20 minutes, so that the target duration may be set to 5 minutes to cover the highlight time in the game; for music type applications, the target duration may be set to 3 minutes to cover a major portion of a song, since a song is approximately 2 to 4 minutes in time.
And step 102, determining a target frame rate according to the target duration.
In the embodiment of the invention, in order to ensure that the data size of the subsequent recorded video does not occupy too much memory so as to avoid that the normal operation condition of the target application is influenced by insufficient memory, the system adjusts the target frame rate of the recorded video according to the target duration input by the user so as to ensure that the data volume of the finally recorded target video data does not exceed the data volume threshold, wherein the data volume threshold is determined according to the memory of the electronic equipment and the memory occupied by the running application.
The process of setting for the target application may be before the target application is started or after the target application software is started.
In the embodiment of the present invention, when the target duration input for the target application is not received or the target duration is less than or equal to the system default duration, the target application may be configured by using the system default duration, the system default duration is used as the target duration, and the system default frame rate is used as the target frame rate of the target application, where the system default duration and the system default frame rate may be preconfigured for the target application, for example, the system default duration of the game application may be 5 minutes, the system default duration of the instant messaging application may be 3 minutes, and the system default frame rate may be preconfigured according to actual needs of the target application, and a specific configuration manner is not limited herein. The target application is configured by setting the default system time length and the default system frame rate, and a user does not need to specially configure the target time length of the target application, so that the user experience of the user in recording a screen picture of the target application is improved.
And 103, recording target video data according to the target frame rate under the condition that the target application is detected to run.
In the embodiment of the present invention, the target application may be one or more application software or/and system applications installed in the electronic device. The electronic device may receive a target duration set by a user for a target application. If the target duration set for the target application is longer than the default duration of the system, it is required to ensure that the data volume of the target video data does not exceed the data volume threshold. Since the target frame rate is inversely proportional to the target duration, the target frame rate can be calculated by formula (1).
F1＝T0/T1×F0 (1)
Wherein, T0 indicates the default duration of the system, T1 indicates the target duration, F0 indicates the default frame rate of the system, and F1 indicates the target frame rate.
According to the embodiment of the invention, the target frame rate for recording the target video data is adjusted when the target time length input by the user is too large, so that the user can flexibly configure the target time length, the data volume of the target video data is ensured not to be too large to influence the normal operation of the target application, and the stability of the dynamic recording process aiming at the target application is improved.
Of course, the user may start a recording end operation, and the electronic device stores the target video data in response to the recording end operation. The recorded video is generally stored in a cache, and then the target video data can be transferred from the cache to a nonvolatile storage device for storage.
In the embodiment of the invention, when the target application starts to run, the screen picture of the target application is automatically recorded according to the target frame rate. The recording process is dynamically circulated, the duration of target video data stored in a memory of the electronic equipment is always kept to be not more than a data volume threshold preset by a system, and the target frame rate of the target video data is adjusted, so that the data volume of the target video data cannot exceed the data volume threshold as long as the duration of the target video data does not exceed the target duration, and unnecessary influence on the normal operation of target applications and other applications in the electronic equipment is avoided.
And 104, reducing the data volume of the target video data according to a preset deletion strategy under the condition that the recording duration is longer than the target duration.
In the embodiment of the present invention, if the length of the video recorded by the user exceeds the target duration, the data volume of the recorded target video data will exceed the data volume threshold, and at this time, the redundant data in the target video data can be deleted by performing configuration adjustment on the target video data. Specifically, the data amount of the target video data may be reduced by adjusting a configuration that affects the video data amount, such as a frame rate and a resolution of the target video data, or compressing the target video data. Further, data in the target video data may be deleted directly, for example, a portion of the video data with high picture similarity, a portion that does not meet the content requirement of the user, and expired video data may be deleted.
In the embodiment of the invention, the user can quickly store the recorded target video data only by inputting the preset selection operation in the running process of the target application after the electronic equipment receives the selection operation, so that the user can conveniently acquire the picture required by the user in the running process of the target application. For example: in the running process of the game application, when the game picture has the wonderful moment, a user can input selection operation and store the recorded target video data, the target video data starts to be recorded when the game starts, and the recording is not triggered by the user after the wonderful moment occurs, so that the wonderful moment required by the user is included, and the user cannot miss the video data of the wonderful moment required to be recorded because the user cannot grasp the recording starting moment in the screen recording process.
The embodiment of the invention provides a first video recording method, which is applied to electronic equipment and comprises the following steps: acquiring a target duration for a target application; determining a target frame rate according to the target duration; under the condition that the target application is detected to run, recording target video data according to the target frame rate; and reducing the data volume of the target video data according to a preset deletion strategy under the condition that the duration of the recording is longer than the target duration. By adjusting the target frame rate according to the target duration and dynamically adjusting the data volume of the recorded target video according to the target duration, the situation that the operation of the target application is affected due to the overlarge memory of the recorded video is avoided, the optimal screen recording time in the application operation process is guaranteed not to be missed by a user, and the user experience of the screen recording function is improved.
Referring to fig. 2, a flowchart of a second video recording method provided in an embodiment of the present invention is shown, where the method is applied to an electronic device, and the method may include:
In the embodiment of the invention, a user can configure the target time length for recording the video data through the target application before recording the video, and if the user does not configure the target time length, the system automatically confirms the default target time length of the system as the target time length so as to reduce the operation required by the user.
In the embodiment of the invention, if the duration of the video recorded by the user does not exceed the target duration, the data volume of the target video data recorded according to the target frame rate does not exceed the data volume threshold, and at this time, the video is recorded according to the target frame rate.
And 203, reducing the frame rate of the recorded target video data according to the duration when the duration of the recording is greater than the target duration.
In the embodiment of the present invention, the process of adjusting the frame rate of the recorded target video data may be specifically determined according to the original target frame rate, the target duration, and the duration. Because the data volume of the recorded target video data is in direct proportion to the duration and the frame rate, the ratio between the adjusted target frame rate and the original target frame rate can be determined according to the ratio between the target duration and the duration, and the adjusted target frame rate is determined under the condition that the original target frame rate is known. For example: the target duration of a certain target application is 20 minutes, the target frame rate is 60 frames, and when the duration is 40 minutes, the target frame rate is adjusted to 30 frames, so as to ensure that the data volume of the recorded target video data is unchanged. Further, in practical application, since the process is a dynamic process, when the distance that the duration of recording approaches the target duration is less than the distance threshold, the frame rate of the recorded target video data can be dynamically adjusted, so as to avoid the influence on the normal operation of the target application caused by the duration exceeding the target.
And 204, under the condition that the duration of the recording is greater than the target duration, reducing the frame rate of the recorded target video data and reducing the target frame rate during the recording according to the duration.
In the embodiment of the present invention, on the basis of the scheme of adjusting the frame rate of the recorded target video data in step 203, the target frame rate during recording may also be adjusted at the same time. Specifically, if the duration of the recorded video exceeds the target duration, it indicates that the data volume of the target video data recorded at the target frame rate exceeds the data volume threshold, the original target frame rate of the recorded video may be adjusted according to the ratio between the duration of the recorded video and the target duration, and the recording may be performed at the adjusted target frame rate, so as to reduce the data volume of the recorded target video data as much as possible, thereby reducing the memory occupied by the recorded video data, and avoiding the situation that the normal operation of the target application is affected by the large data volume of the recorded target video book. And changing the frame rate of the recorded target video data to the adjusted target frame rate while adjusting the target frame rate of the recorded video. In practical application, at least one preset time node can be preset according to the target duration, and each preset time node has different duration and target frame rate. And when the recording duration reaches a preset time node, adjusting the target frame rate to a target frame rate corresponding to the preset time node, and adjusting the frame rate of the recorded target video data to the adjusted target frame rate. For example: the target duration of a certain target application is 10 minutes, the target frame rate is 80 frames, two preset time nodes are set to be 5 minutes and 15 minutes respectively, and the corresponding target frame rates are 40 frames and 20 frames respectively. When the recording duration reaches 5 minutes, the recorded target frame rate is adjusted to 40 frames in advance, the frame rate of the recorded target video data is adjusted to 40 frames, and when the recording duration reaches 15 minutes, the recorded target frame rate is adjusted to 20 frames in advance, and the frame rate of the recorded target video data is adjusted to 20 frames.
Compared with the scheme in step 203, the dynamic frame rate adjustment method does not need to adjust the frame rate of the recorded target video data continuously after the target frame rate is adjusted, thereby saving data processing resources and further effectively avoiding the situation that the normal operation of the target application is affected by the overlarge data amount of the recorded target video data.
The scheme for adjusting the target frame rate in step 203 and step 204 may be selected according to actual requirements, and is not limited herein.
In the embodiment of the invention, a user can configure the preset screen area of the recording screen for the target application, and record the screen picture of the specified area or the specified window of the target application software after configuration, wherein the configuration process can be performed before the recording process or during the recording process, and the user can configure the preset screen area according to the actual requirement. By configuring the screen recording area, the flexibility of the screen recording function for the target application is improved.
In the process of recording the target application, a user can pause recording the target video data through a first operation acting on the electronic equipment, generate a section of target video data from the recorded video, and can re-record a second section of target video data through a second operation acting on the electronic equipment, so that the target video data can have multiple sections in the whole recording process. It can be understood that a user may perform the first operation and the second operation multiple times, so that multiple segments of target video data are generated in the running process of the target application, and in a time period between the first operation and the second operation, the content displayed by the target application is not recorded, so that the recorded target video data better meets the user requirements. The first operation and the second operation may be simultaneous pressing of a key combination in the electronic device, or sequential pressing of a case combination in the electronic device, and the key combination and the pressing mode respectively corresponding to the first operation and the second operation may be determined by a user through preset, or may be default by a system; the first operation and the second operation may also be touch screen operations acting on a sensing screen of the electronic device, a user may trigger the touch screen operations by performing sliding operations on the screen of the electronic device, and a specific manner of the first operation and the second operation may be configured according to a command receiving function of the electronic device and actual needs of the user, which is not specifically limited herein.
According to the embodiment of the invention, the video is recorded for many times according to the operation of the user in the process of recording the target application, so that the time period which is not wanted to be recorded by the user can be skipped over in the process of recording the dynamic video screen aiming at the target application, and the flexibility of the video recording process is improved.
And step 206, responding to the selection operation, splicing at least two sections of target video data selected by the selection operation to obtain spliced target video data.
After the process of recording the screen image of the target application is completed, a user can select the recorded multiple sections of target video data according to own requirements through selection operation acting on the electronic equipment, and splice at least two sections of selected target video data to obtain final target video data, wherein the target video data which are not selected by the selection operation can be stored individually, and the target video data which are not selected can also be deleted to reduce the data storage pressure of the electronic equipment deployed by the target application. According to the method, after the process of recording the target application, the currently recorded multiple sections of target video data are spliced according to selection operation, so that the recorded target video data can be freely spliced according to user requirements, and the flexibility of video recording for the target application is improved.
In the second video recording method provided by the embodiment of the present invention, the recorded target frame rate and the frame rate of the recorded target video data are dynamically adjusted according to the recording duration in the video recording process, so that a situation that the operation of a target application is affected due to an excessive memory of the recorded video is avoided, and a user can stop and continue the recording process through an input operation, so that the user is ensured not to miss the optimal screen recording time in the application operation process, and the user experience of the application screen recording function is improved.
Referring to fig. 3, a flowchart of a second video recording method provided in an embodiment of the present invention is shown, where the method is applied to an electronic device, and the method may include:
This step can refer to the detailed description of step 201, and is not described herein again.
This step can refer to the detailed description of step 103, which is not repeated herein.
In the embodiment of the present invention, the expired video data refers to a portion of video data that is recorded first and exceeds a target duration in the target video data. When the duration of the recorded target video data does not exceed the target duration, continuously recording a screen picture of a target application, and when the duration of the recording exceeds the target duration, deleting outdated video data in the recording process in order to ensure that the target video data does not exceed a data volume threshold, so that the duration of the target video data does not exceed the target duration while continuously recording the target video data in a recording and deleting mode. The deleting process may be performed according to a preset frequency, and when the target video data exceeds the target duration preset duration, the video data with the preset duration recorded first in the target video data is deleted, for example, when the length of the target video data exceeds 5 seconds, the data in the first 5 seconds of the target video data is deleted, where the preset frequency may be determined according to the size of a memory of the electronic device and the size of a memory occupied by application software running.
This step can refer to the detailed description of step 205, which is not repeated herein.
And 305, responding to the selection operation, splicing at least two sections of target video data selected by the selection operation to obtain spliced target video data.

The third video recording method provided in the embodiment of the present invention dynamically deletes the first recorded data exceeding the target duration in the process of recording the video while adjusting the target frame rate according to the target duration, thereby not only avoiding the situation that the operation of the target application is affected by an excessive memory of the recorded video, but also ensuring that the user does not miss the optimal screen recording time in the process of operating the application, and improving the user experience of the screen recording function.
