In summary, the embodiment of the present application provides a screen recording method for a mobile terminal, where the mobile terminal may adjust the volume of a collected audio stream to an initial volume in a screen recording process, and may also adjust the volume of the collected audio stream to a target volume in response to a volume adjustment instruction. The mobile terminal provided by the embodiment of the application supports adjustment of the volume of the acquired audio stream in the screen recording process, so that the screen recording flexibility of the mobile terminal is effectively improved.
Fig. 2 is a flowchart of another screen recording method of a mobile terminal according to an embodiment of the present application, where the method may be applied to a mobile terminal. Referring to fig. 2, the method may include:
In the process of recording the screen of the mobile terminal, the mobile terminal can adjust the volume of the collected audio stream to the initial volume in real time.
The initial volume may be determined by the mobile terminal in response to a volume setting operation of the user before screen recording, or may be a default volume pre-stored in the mobile terminal. The volume of the collected audio stream may be a system volume of the mobile terminal, and the system volume may refer to a current volume of a speaker of the mobile terminal. That is, the mobile terminal may adjust the volume of the acquired audio stream from the system volume to the initial volume.
The audio stream collected by the mobile terminal may include: an audio stream captured by a microphone of the mobile terminal, and/or an audio stream in a play state in the mobile terminal (may also be referred to as a system audio stream). That is, in the process of recording the screen, the mobile terminal may collect the audio stream through the microphone, and/or collect the audio stream in the playing state in the mobile terminal.
For example, the audio stream captured by the mobile terminal may include: the audio stream collected by the microphone and the audio stream which is stored in the mobile terminal in advance and is in a playing state. In the process of recording the screen, the mobile terminal can acquire the audio stream through the microphone and can acquire the audio stream in the playing state in the mobile terminal.
Optionally, the audio stream in the playing state may include at least one audio stream.
In this embodiment of the present application, if the audio stream collected by the mobile terminal includes: through the audio stream collected by the microphone and the audio stream in the playing state, the process of the mobile terminal adjusting the volume of the collected audio stream to the initial volume may include:
the mobile terminal adjusts the volume of the audio stream collected by the microphone to a first initial volume, and adjusts the volume of the collected audio stream in the playing state to a second initial volume. Wherein the second initial volume may be different from the first initial volume.
Therefore, the mobile terminal provided by the embodiment of the application supports adjusting the volume of the audio stream collected by the microphone and the volume of the collected audio stream in the playing state to different volumes. Therefore, the screen recording flexibility of the mobile terminal is further improved, the playing effect of the subsequently synthesized screen recording file can be ensured, and the user experience is effectively improved.
For a scene in which the audio stream in the playing state includes a plurality of audio streams, the mobile terminal may adjust the volumes of the plurality of audio streams to the second initial volume. I.e. the adjusted volume of the plurality of audio streams in the playing state is the same.
In the embodiment of the present application, the volume is determined by the amplitude (i.e., amplitude) of the vibration of the object, and the larger the amplitude is, the larger the volume is; the smaller the amplitude, the smaller the volume. Based on this, the process of the mobile terminal adjusting the audio collected by the microphone to the first initial volume and adjusting the volume of the collected audio stream in the playing state to the second initial volume may include:
the mobile terminal determines a first initial amplitude corresponding to the first initial volume and determines a second initial amplitude corresponding to the second initial volume based on a relationship between the volume and the amplitude which is stored in advance. Then, the mobile terminal may adjust the amplitude of the audio stream collected by the microphone to a first initial amplitude during the screen recording process, and may adjust the amplitude of the collected audio stream in the playing state to a second initial amplitude.
In the embodiment of the application, a screen recording application can be installed in the mobile terminal. After the mobile terminal runs the screen recording application, a first selection control for acquiring the audio stream through the microphone and a second selection control for acquiring the system audio stream can be displayed. Optionally, the first selection control and the second selection control may be switch controls.
If the user selects the first selection control, the mobile terminal may load audio parameters (such as a sampling rate, a bit rate, and the like) for a process of acquiring an audio stream by using a microphone after a screen recording is started (i.e., a screen recording instruction is received) in response to a selection operation of the user for the first selection control, that is, the process of acquiring an audio stream by using a microphone is initialized, and an audio stream is acquired by using a microphone after the initialization is completed. If the user selects the second selection control, the mobile terminal may respond to a selection operation of the user for the second selection control, initialize a process of acquiring the audio stream in the playing state after the screen recording is started, and acquire the audio stream in the playing state after the initialization is completed. If the mobile terminal selects the first selection control and the second selection control, the mobile terminal may respond to the selection operation of the user for the first selection control and the second selection control, initialize the process of acquiring the audio stream through the microphone and the process of acquiring the audio stream in the playing state after the screen recording is started, acquire the audio stream through the microphone after the initialization is completed, and acquire the audio stream in the playing state.
In this embodiment, after the screen recording starts, the mobile terminal may collect an audio stream collected by the microphone from a first buffer (also referred to as a first buffer queue), and adjust the volume of the audio stream collected from the first transfer area to a first initial volume. And, the mobile terminal may further collect an audio stream in a playing state from a second buffer (also referred to as a second buffer queue), and adjust a volume of the audio stream collected from the second buffer to a second initial volume.
For example, it is assumed that the first selection control and the second selection control are both switch controls, and the first initial volume and the second initial volume are both default volumes. Referring to fig. 3, the user touches the application identifier of the screen recording application in the mobile terminal. Correspondingly, the mobile terminal can respond to the touch operation of the user for the application identifier, and the floating window is displayed on the desktop of the mobile terminal. A screen recording control 01 and a setting control 02 may be displayed in the floating window.
The user touches the setting control 02, and accordingly, the mobile terminal can respond to the selection operation of the user for the setting control 02, and display the first switch control 03 acquired by the microphone and the second switch control 04 for acquiring the system audio stream.
The user touches the first switch control 03 and the second switch control 04. Correspondingly, the mobile terminal may determine to acquire the audio stream through the microphone after the screen recording starts in response to the touch operation of the user on the first switch control 03 and the second switch control 04, and acquire the audio stream in the playing state in the mobile terminal.
After completing the setting of the sound source (i.e., the above-mentioned collecting by the microphone and the system audio stream collecting), the user can touch the screen recording control 01 in the floating window. Correspondingly, the mobile terminal can respond to a screen recording instruction triggered by the touch operation of the user on the screen recording control 01 to start screen recording, adjust the volume of the audio stream acquired by the microphone to a first initial volume in real time in the screen recording process, and adjust the volume of the acquired system audio stream to a second initial volume.
After the screen recording is started, the mobile terminal can display an interface in the screen recording process in the floating window. Referring to fig. 3, the interface during the screen recording process displays a setting control 02, a pause control 05, and a current recording duration T (in this case, T is 00:00:10, i.e., 10 seconds).
In addition, as can be seen from fig. 3, applications for users to enjoy leisure, such as reading applications, music applications, chat applications, video applications, game applications, and applications for providing basic services to users, such as applications for calls, short messages, address books, browsers, clocks, cameras, galleries, and settings, may be installed in the mobile terminal. Also, the mobile terminal 110 may display the current time, the current weather, and the temperature.
In the screen recording process, the mobile terminal can receive a volume adjusting instruction. The volume adjustment instruction may be used to instruct real-time adjustment of the volume of the captured audio stream to a target volume.
Optionally, the process of the mobile terminal receiving the volume adjustment instruction for instructing to adjust the volume to the target volume may include:
the mobile terminal receives the volume setting instruction firstly and responds to the volume setting instruction to display the volume adjusting control. The volume adjustment control may include a slider and a slider located on the slider, and a position of the slider on the slider may be used to indicate a volume level.
Then, the user can touch the volume adjustment control, and correspondingly, the mobile terminal receives a volume adjustment instruction triggered by the touch operation of the user on the volume adjustment control. And the volume corresponding to the action position of the touch operation is the target volume.
In the embodiment of the application, a user can touch any position on the slider of the volume adjustment control. Accordingly, the mobile terminal may receive a volume adjustment instruction triggered by the touch operation. Alternatively, the user may drag the slider to move on the slider bar. After stopping moving the slider, the mobile terminal may receive a volume adjustment command triggered by the moving operation.
Optionally, for a scene in which the captured audio stream includes the audio stream captured by the microphone and the system audio stream, the mobile terminal may display, in response to the volume setting instruction, a first volume adjustment control for adjusting the volume of the audio stream captured by the microphone and a second volume adjustment control for adjusting the volume of the system audio stream.
And step 203, responding to the volume adjusting instruction, and adjusting the volume of the audio stream acquired after receiving the volume adjusting instruction to the target volume.
After receiving the volume adjusting instruction, the mobile terminal can respond to the volume adjusting instruction and adjust the volume of the audio stream acquired after receiving the volume instruction to the target volume in real time. That is, the mobile terminal may adjust the volume of the audio stream collected after receiving the volume instruction to the target volume from the system volume.
In this embodiment of the present application, if the audio stream collected by the mobile terminal includes: through the audio stream collected by the microphone and the audio stream in the playing state, the process of the mobile terminal adjusting the volume of the collected audio stream to the target volume may include:
the mobile terminal may adjust, in response to the volume adjustment instruction, the volume of the audio stream collected through the microphone after receiving the volume adjustment instruction to a first target volume, and may adjust, in response to the volume adjustment instruction, the volume of the audio stream in the play state collected after receiving the volume adjustment instruction to a second target volume. Wherein the second target volume may be different from the first target volume.
Therefore, the mobile terminal provided by the embodiment of the application can adjust the volume of the audio stream acquired by the microphone in the screen recording process, adjust the volume of the acquired audio stream in the playing state, and adjust the volume of the audio stream and the volume of the audio stream in the playing state to different volumes. Therefore, the screen recording flexibility of the mobile terminal is effectively improved, and the user experience can be improved.
Optionally, for a scene in which the audio stream in the playing state includes multiple audio streams, the mobile terminal may adjust the volumes of the multiple audio streams collected after receiving the volume adjustment instruction to the second target volume.
In this embodiment of the application, the process of adjusting the volume of the audio stream collected by the microphone to the first target volume and adjusting the volume of the audio stream in the playing state to the second target volume by the mobile terminal may include:
the mobile terminal may determine a first target amplitude corresponding to the first target volume and determine a second target amplitude corresponding to the second target volume based on a relationship between the volume and the amplitude stored in advance. After that, the mobile terminal may adjust the amplitude of the audio stream collected by the microphone to a first target amplitude after receiving the volume adjustment instruction, and may adjust the amplitude of the collected audio stream in the playing state to a second target amplitude.
For example, the mobile terminal may store a correspondence relationship between the system volume, the target volume, and the amplitude scaling factor in advance. The mobile terminal may determine a first scaling factor corresponding to the first target volume from the corresponding relationship based on the first target volume and the current system volume of the mobile terminal, and may determine a second scaling factor corresponding to the second target volume from the corresponding relationship based on the second target volume and the current system volume.
Thereafter, the mobile terminal may multiply the amplitude of the audio stream collected by the microphone by the first scaling factor, thereby adjusting the volume of the audio stream collected by the microphone to a first target volume. And the mobile terminal may multiply the amplitude of the collected audio stream in the playing state by the second scaling factor, so as to adjust the volume of the collected audio stream in the playing state to a second target volume.
Optionally, for a scene in which the volume adjustment instruction is triggered by a touch operation for the volume adjustment control, before adjusting the volume of the acquired audio stream to the target volume, the mobile terminal may further determine, in response to the volume adjustment instruction, the volume corresponding to the action position of the touch operation as the target volume.
In addition, in this scenario, if the volume adjustment instruction is triggered by a touch operation on a slider of the volume adjustment control, the mobile terminal may further move the slider from the previous position to the action position in response to the volume adjustment instruction.
For example, assuming that the volume adjustment instruction received by the mobile terminal is triggered by the user touching any position on the slider bar, referring to fig. 4, in the screen recording process, the user touches the setting control 02. Accordingly, the mobile terminal may receive a volume setting instruction triggered by a touch operation of the user on the setting control 02, and may display the first volume adjustment control 06 and the second volume adjustment control 07 in response to the volume setting instruction. The first volume adjustment control 06 may include a first slider 061 and a first slider 062 disposed on the first slider 061. The second volume adjustment control 07 may include a second slider bar 071 and a second slider 072 located on the second slider bar 071.
As can be seen from fig. 3, the first slider 062 is now located at position x1 on the first slider bar 061, and the second slider 072 is located at position y1 on the second slider bar 071.
The user touches the second slider 071 of the second volume adjustment control 07, and the active position of the touch operation is position y2 shown in fig. 3. Accordingly, the mobile terminal receives a volume adjustment instruction triggered by the user for the touch operation, and may move the second slider 072 from the position y1 to the position y2 of the second slider 071 in response to the volume adjustment instruction. And, the mobile terminal may further determine the volume corresponding to the position y2 as a second target volume, and may adjust the volume of the audio stream in the playing state, which is acquired after receiving the volume adjustment instruction, to the second target volume.
In the same operation as for the second volume adjustment control 07, as shown in fig. 3, the touch position of the user with respect to the first slider 061 of the first volume adjustment control 06 is position x 2. Accordingly, the mobile terminal may receive a volume adjustment instruction by a touch operation of the user, and may move the first slider 062 from the position x1 of the first slider bar 061 to the position x2 in response to the volume adjustment instruction. And, the mobile terminal may further determine the volume corresponding to the position x2 as the first target volume, and may adjust the volume of the audio stream captured by the microphone after receiving the volume adjustment instruction to the first target volume.
And step 204, synthesizing the acquired audio stream with image data acquired by recording the screen.
The mobile terminal can synthesize the acquired audio stream with the image data acquired by recording the screen in real time, so that a screen recording file is obtained. Wherein the audio stream for synthesizing with the image data is a volume-adjusted audio stream.
In this embodiment of the application, for a scene in which the acquired audio stream includes an audio stream acquired by a microphone and an audio stream in a playing state, the mobile terminal may synthesize the audio stream acquired by the microphone and the audio stream in the playing state in real time to obtain a mixed audio stream. And then, the mobile terminal can synthesize the mixed audio stream and the image data obtained by recording the screen to obtain a screen recording file.
Optionally, after obtaining the mixed audio stream, the mobile terminal may perform compression coding on the mixed audio stream by using an audio encoder in the mobile terminal. Then, the mobile terminal may use a media synthesizer therein to encapsulate the compressed and encoded mixed audio stream and the image data into a playable video file, thereby obtaining a screen recording file.
In the embodiment of the application, after the screen recording is started, the mobile terminal acquires the audio stream through the microphone and acquires the audio stream which is stored in advance and is in a playing state. That is, after the screen recording is started, the audio stream collected by the mobile terminal includes: audio streams collected by a microphone and audio streams in a play state. The mobile terminal may also perform the following steps during the recording process.
In the process of recording the screen, if the mobile terminal receives a first acquisition stopping instruction for the microphone, the mobile terminal may stop acquiring the audio stream through the microphone in response to the first acquisition stopping instruction.
Alternatively, the mobile terminal may turn off the microphone in response to the first stop collecting instruction, thereby stopping collecting the audio stream through the microphone.
Optionally, the mobile terminal may display a first selection control acquired by the microphone in the screen recording process, and may detect whether a deselection operation for the first selection control is received. If the mobile terminal receives the deselection operation, a first acquisition stopping instruction triggered by the deselection operation may be received.
For example, assuming that the first selection control is a switch control, referring to fig. 5, the user touches a setting control 02 included in an interface displayed during the screen recording process. Accordingly, the mobile terminal may display the first switch control 03 in response to the touch operation for the setting control 02. As shown in fig. 5, the first switch control 03 is in an open state at this time.
Thereafter, the user can touch the first switch control 03 in the open state. Accordingly, the mobile terminal may receive a first acquisition stopping instruction triggered by a touch operation of the user on the first switch control 03, and may stop acquiring the audio stream through the microphone in response to the first acquisition stopping instruction.
In the process of recording the screen, if the mobile terminal receives a second acquisition stopping instruction for the audio stream in the playing state, the acquisition of the audio stream in the playing state may be stopped in response to the second acquisition stopping instruction.
Optionally, the mobile terminal may display a second selection control for acquiring the audio stream of the system in the screen recording process, and may detect whether a deselection operation for the second selection control is received. If the mobile terminal receives the deselection operation, a second acquisition stopping instruction triggered by the deselection operation may be received.
For example, assuming that the second selection control is a switch control, referring to fig. 6, the user touches a setting control 02 included in the interface displayed in the screen recording process. Accordingly, the mobile terminal may display the second switch control 04 in response to the touch operation for the setting control 02. As shown in fig. 6, the second switch control 04 is in an open state at this time.
Thereafter, the user may touch the second switch control 04 in the open state. Correspondingly, the mobile terminal may receive a second acquisition stopping instruction triggered by the touch operation of the user on the second switch control 04, and may stop acquiring the audio stream in the playing state in the mobile terminal in response to the second acquisition stopping instruction.
