[0023] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0026] First of all, it should be noted that ValueAnimator: the attribute animation in Android development, it can realize attribute animation effects such as scaling, translation, rotation, etc. Here I use its attribute value change monitoring to continuously control the volume value from 0-1 (or 1-0). Here and below, 0 is equivalent to mute, and 1 is equivalent to the original volume set by the system for multimedia.

[0027] VideoPlayer: Android develops its own player, which can be ExoPlayer, IJKPlayer, or other customized MediaPlayer.

[0028] VideoUI: Video playback interface, including a video presentation interface and button controls on the video, such as play / pause, previous / next, progress bar and other button components.

[0029] Figure 1 It is a schematic diagram of an implementation environment of a method for controlling gradual sound change in video playback shown in an exemplary embodiment of the present application.

[0030] like Figure 1 As shown, the implementation environment diagram of the sound gradient control method in video playback includes a data acquisition device (or interface) 101 and a computer device 102. Among them, the data acquisition device or interface 101 is responsible for collecting original data related to video playback, which includes but is not limited to basic information of the video (such as playback address, title, duration, etc.), user preference information and status information of the playback device. The data acquisition device can be a sensor or interface integrated in the playback device (such as a touch screen, remote control, etc.), or it can be data collected by an external device after being connected to the playback device wirelessly or wired. This application does not impose any restrictions on the specific implementation form of the data acquisition device or interface.

[0031] The computer device 102 is used to process the raw data collected by the data acquisition device or the interface 101, and control the audio output of the video according to the attribute animation, specifically including setting the local variables of the attribute animation, i.e., the preset duration of the attribute animation and the linear change value of the volume within the preset duration, and then controlling the target video to be played according to the attribute animation, so that when the target video is played, its volume is gradually increased or reduced within the preset duration. The computer device 102 can be a high-performance processor, a dedicated video playback computing platform, or an embedded system integrated on a playback device. The present application does not impose any restrictions on the specific type of the computer device either. In this way, the system can provide users with a smooth and comfortable volume transition experience in different playback environments, improve the quality of video playback and user satisfaction.

[0032] Figure 2 It is a flowchart of a method for controlling gradual sound change in video playback, shown as an exemplary embodiment of the present application.

[0033] like Figure 2 As shown, in an exemplary embodiment, the method for controlling the gradual change of sound in video playback includes at least steps S210 to S230, which are described in detail as follows:

[0034] Step S210, obtaining video information corresponding to the target video to be played.

[0035] In one embodiment of the present application, after obtaining the video information corresponding to the target video to be played, it also includes: transmitting the video information to the video playback interface, so as to forward the video to be played to the video player based on the video playback interface, and the video player is encapsulated in the video playback interface.

[0036] In a specific embodiment of the present application, when implementing video playback in an Android application, it is first necessary to obtain the target video information selected by the user from a video list. When the user clicks on a video item in the video list, the application captures key information such as the playback address, title, and duration of the video, which is then encapsulated and passed to a new activity VideoUI, i.e., the video playback interface, through an intent. Once the VideoUI activity is started, it will extract the relevant data of the video from the received intent. Next, VideoUI will initialize a custom video player component VideoPlayer and pass all the previously acquired video information to this player. VideoPlayer is responsible for handling the actual video playback tasks, including setting the media source, preparing the player, and starting to play the video.

[0037] Step S220, parsing the video information to obtain the target video.

[0038] In one embodiment of the present application, after parsing the video information, it also includes: verifying the video information, generating a video playback signal if the verification is successful, and feeding back the video playback signal to the video playback interface; the information verification includes at least one of the following: checking whether the playback address in the video information is valid, if so, it is deemed to have been verified; verifying whether the format in the video information complies with the preset media format standard, if so, it is deemed to have been verified; checking whether the video length in the video information meets the preset duration range, if so, it is deemed to have been verified.

[0039] In a specific embodiment of the present application, in an Android application, when a user selects a video from a video list to play, the system first parses the information of the selected video (such as the playback address, title, and duration). Subsequently, the system performs a series of verification steps on this information to ensure its validity. These verifications include checking whether the playback address of the video is accessible, confirming whether the video format meets the preset media format standard (such as MP4 or AVI), and verifying whether the video duration is within a reasonable range. If all verifications are passed, a video playback signal is generated and the signal is fed back to the video playback interface VideoUI.

[0040] After receiving the video playback signal, VideoUI starts the VideoPlayer component encapsulated inside it and passes the verified video information to it. VideoPlayer configures itself based on this information and starts loading and playing the video content. During the whole process, in order to provide a better user experience, some additional features can be added, such as displaying a loading progress bar or implementing a volume fade-in effect, so that users can perceive that the video is preparing to play and is about to start.

[0041] It can be understood that through strict verification of video information, only valid and standard-compliant videos can be played, reducing playback failures caused by invalid links or incompatible formats; effective information verification avoids unnecessary data processing and network requests, thereby saving computing resources and bandwidth; and it can effectively prevent malicious or damaged video files from entering the playback process, protecting user devices from potential security threats.

[0042] Step S230, playing the target video according to the attribute animation, so that when the target video is played, its volume gradually increases or decreases within a preset duration; wherein the attribute animation is created based on pre-configured local variables, and the local variables include a preset duration and a linear change value of the volume within the preset duration.

[0043] In one embodiment of the present application, a property animation is created based on preconfigured local variables, including: creating a property animation from an initial value to a final value, and setting the duration of the property animation based on the local variables, so that the property value of the property animation changes from the initial value to the final value within the duration; adding an update listener to the created property animation, and the update listener is valid during the execution of the property animation.

[0044] In a specific embodiment of the present application, in an Android application, in order to achieve a smooth fade-in effect of the volume during video playback, a property animation (ValueAnimator) can be created based on a pre-configured local variable. First, use this local variable to create a property animation from an initial value to a final value, for example, from 0 to 1, indicating that the volume gradually increases from silent to maximum. At the same time, set the duration of the animation, such as 500 milliseconds (0.5 seconds), to ensure that the animation completes the change from the initial value to the final value within this period of time. Next, add an update listener to this property animation, which will be continuously called during the execution of the animation. Whenever the current value of the animation changes, the listener will receive the new value and adjust the volume or other related properties in real time accordingly.

[0045] It can be understood that, first of all, by changing the property value linearly or nonlinearly within a certain period of time, property animation can provide a very natural and smooth transition effect, which significantly improves the user experience. Secondly, developers can flexibly set the start value, end value and duration of the animation according to specific needs, and even customize the interpolator to control the change curve of the animation, so as to achieve richer visual effects. In addition, ValueAnimator provides an efficient animation mechanism, which triggers callbacks only when the interface needs to be updated, reducing unnecessary computing overhead and ensuring the smooth operation of the application. This method also makes the code more modular, which is convenient for later maintenance and function expansion. Finally, since ValueAnimator is one of the standard animation APIs provided by the Android system, it has good backward compatibility and can work stably on different versions of Android devices, ensuring the consistency and reliability of the application. In summary, creating and managing property animations based on pre-configured local variables can not only improve the interactive experience of the user interface, but also improve development efficiency and application performance.

[0046] In one embodiment of the present application, before playing the target video according to the attribute animation, it also includes: identifying the creation status of the attribute animation according to the attribute variable; wherein, when the value of the attribute variable is empty, the creation status of the attribute animation is determined to be uncreated, and when the value of the attribute variable is not empty, the creation status of the attribute animation is determined to be created; if the creation status of the attribute animation is created, then identifying the playback status of the created attribute animation, the playback status includes playing and playback ended; if the playback status of the attribute animation is playing, then stopping the attribute animation, and clearing the animation record that has been played, and played includes playback stopped and playback ended.

[0047] In a specific embodiment of the present application, in an Android application, in order to ensure that attribute animations (such as volume fade-in effects) can be correctly created and managed, a series of status checks are required before playing the target video. First, a local variable is defined to store an instance of the attribute animation. When preparing to play the video, the creation status of the attribute animation is identified by checking the value of this local variable: if the variable is empty, it means that the attribute animation has not been created; if the variable is not empty, it means that the attribute animation has been created.

[0048] Once it is confirmed that the property animation has been created, the next step is to further identify the current playback state of the animation. The playback state can be divided into "playing" and "end of playback". By calling a specific method to determine whether the animation is playing. If the animation is found to be playing, the system will immediately stop the current animation and clear the played animation record. Specifically, the operation of stopping the animation includes calling the cancel method to interrupt the execution of the animation, and setting the local variable to null to release memory resources and clear the reference to the old animation.

[0049] Subsequently, the system creates a new property animation. This new animation changes from the initial value to the final value, for example, from 0 to 1, indicating that the volume gradually increases from silent to maximum. The duration of the animation is also set to a fixed value, such as 500 milliseconds (0.5 seconds). Next, add an update listener to the newly created animation, which will be called continuously during the execution of the animation. Whenever the current value of the animation changes, the listener will receive the new value and adjust the volume or other related properties in real time accordingly.

[0050] Finally, the newly created property animation is started and the video begins to play. It is understandable that in this way, it is ensured that each time the video is played, the property animation is a new animation that starts from the beginning, avoiding problems caused by repeated starts or uncleaned animations. This practice not only prevents memory leaks, but also ensures that users can experience a consistent and expected volume fade-in effect every time, thereby improving the user's audio-visual experience and the overall performance of the application. In addition, this approach also enhances the maintainability of the code, making the development and debugging process more efficient.

[0051] In one embodiment of the present application, playing a target video according to an attribute animation includes creating an attribute animation, configuring local variables of the attribute animation, and then synchronously starting the attribute animation when the target video is displayed.

[0052] In a specific embodiment of the present application, playing a target video according to an attribute animation also includes: during the execution of the animation, dynamically obtaining a linear change value from an initial value to a final value; and setting the linear change value as a volume value in an audio player to adjust the volume of the player.

[0053] In a specific embodiment of the present application, in an Android application, in order to achieve a smooth fade-in effect of the volume when playing a video, a property animation (ValueAnimator) can be used to dynamically adjust the volume of the audio player. The specific process is as follows:

[0054] Before preparing to play the target video, first check and process the status of the existing property animation. If there is already a property animation created and playing, stop the animation and clear the record to avoid problems caused by repeated starts or uncleaned animations.

[0055] Next, create a new property animation that changes from an initial value of 0 to a final value of 1, indicating that the volume gradually increases from silent to maximum. Set the duration of the animation to 500 milliseconds (0.5 seconds) to ensure that the change from the initial value to the final value is completed within this time.

[0056] Add an update listener to the newly created property animation. This listener will be called continuously during the animation, and each time the current value of the animation changes, the listener will receive new values. These values ​​are linearly changing between 0 and 1, reflecting the gradual increase in volume.

[0057] In the listener, the received linear change value is set as the volume value in the audio player. The audio player usually provides a setVolume method. By calling this method and passing the linear change value, the volume of the player can be adjusted in real time, thereby achieving a smooth transition of the volume.

[0058] Finally, start the property animation, start playing the video, and gradually increase the volume from silent to maximum. In this way, you can ensure that every time you play a video, the volume can smoothly transition from silent to maximum, providing a natural and smooth audio-visual experience.

[0059] It can be understood that the method proposed based on this implementation not only improves the performance and stability of the application, but also significantly enhances the user experience. Through clear state management and resource release, the code is more robust and easy to maintain; in addition, the smooth volume transition effect makes the video playback more natural and smooth, improving user satisfaction.

[0060] Figure 3 This is a schematic diagram of an exemplary embodiment of the present application showing the entire process of video playback.

[0061] In a specific embodiment of the present application, Figure 3 As shown, when the user clicks on a video as the target video from the video list, the video information of the target video is sent to the video playback interface and the target video player, so that the video information is verified based on the target video player, and after the verification is passed, the video screen is played based on the video playback interface player, and the target animation controller is started at the same time, so as to control the output of the audio information of the target video based on the animation control parameters of the target animation controller, and finally the video screen and the controlled output audio are fed back to the user.

[0062] In a specific embodiment of the present application, when a user clicks a video from a video list as a target video, the system captures the relevant information of the video, including the playback address, title, and duration, and passes this information to the video playback interface VideoUI through an intent. After receiving the video information, VideoUI forwards it to the target video player VideoPlayer encapsulated inside.

[0063] VideoPlayer first verifies the video information, including checking the validity of the playback address to ensure that it can be loaded; verifying whether the video format conforms to the preset media format standard (such as MP4, AVI, etc.); and verifying whether the video length is within a reasonable range (for example, between 10 seconds and 60 minutes). If all verifications pass, VideoPlayer starts preparing to play the video and displays the video screen in VideoUI.

[0064] At the same time, the system creates a property animation (ValueAnimator) and sets it to change from an initial value of 0 to a final value of 1 with a duration of 500 milliseconds. An update listener is added to this property animation, and the listener will continuously receive new linear change values ​​during the animation execution. In the update listener, the received linear change value is set as the volume value to the audio player, thereby achieving a smooth transition of the volume.

[0065] Then, the attribute animation is started and the video screen is played at the same time. As the attribute animation is executed, the volume gradually increases from silent to maximum, and the user can see the video screen and hear the audio with smooth transition processing. Finally, the user can get a natural and smooth audio-visual experience.

[0066] It can be understood that the method proposed in this embodiment not only ensures the validity and compatibility of video information, but also provides a smooth volume fade-in effect, improving the user's audio-visual experience. Therefore, not only the performance and stability of the application are improved, but also the user experience is significantly enhanced, making the video playback more natural and smooth, and improving user satisfaction. In addition, clear state management and resource release also make the code more robust and easy to maintain.

[0067] In addition, if the content to be played is audio information, it is transmitted to the audio player through the audio playback interface, which specifically includes: parsing the audio information to obtain the target audio; playing the target audio according to the attribute animation, so that when the phonetic video is played, its volume gradually increases or decreases within a preset duration; wherein the attribute animation is created based on pre-configured local variables, and the local variables include a preset duration and a linear change value of the volume within the preset duration.

[0068] In a specific embodiment of the present application, when a user clicks an audio file from the audio list, the system captures the relevant information of the audio, including the playback address, title, and duration, and passes this information to the audio playback interface AudioUI through an intent. After receiving the audio information, AudioUI forwards it to the audio player AudioPlayer encapsulated inside.

[0069] AudioPlayer parses the audio information to obtain the specific data of the target audio file. Next, the system creates a property animation (ValueAnimator) to control the gradual increase or decrease of the volume. First, define a local variable mVolumeAnimator to store the instance of the property animation, and set the preset duration to 500 milliseconds (0.5 seconds), indicating the duration of the volume change. Based on this local variable, create a property animation that changes from an initial value of 0 to a final value of 1, with a duration of 500 milliseconds.

[0070] Add an update listener to this property animation. The listener will be called continuously during the animation execution. Whenever the current value of the animation changes, the listener will receive the new linear change value. In the update listener, the received linear change value is set as the volume value to the audio player to achieve a smooth transition of the volume.

[0071] Then, the property animation is started and the target audio is played at the same time. As the property animation is executed, the volume gradually increases from silent to maximum (or gradually decreases from maximum to silent), and the user can hear the effect of smooth volume transition. Ultimately, the user can get a natural and smooth listening experience.

[0072] It can be understood that the method proposed in this example not only ensures the validity and compatibility of audio information, but also provides a smooth volume fade-in or fade-out effect, which improves the user's auditory experience. It not only improves the performance and stability of the application, but also significantly enhances the user experience, making audio playback more natural and smooth, and improving user satisfaction. In addition, clear state management and resource release also make the code more robust and easy to maintain.

[0073] Finally, it should be emphasized that the sound gradient control method in video playback proposed in this application has many beneficial effects, especially in improving user experience and enhancing application performance. Specifically, the method controls the sound gradient of video or audio during playback through attribute animation (ValueAnimator), including the gradual increase of sound when starting to play and the gradual decrease of sound when pausing / stopping playback, and can accurately control the specific duration and change rate of its sound change. The following are the main beneficial effects of the method: First, the volume gradient effect achieved by attribute animation enables users to hear the volume gradually increase from mute to maximum when the video or audio starts to play, and the volume gradually decreases from maximum to mute when pausing or stopping playback. Its smooth transition effect avoids abrupt sound changes and provides a more natural and smooth auditory experience. Second, this method allows developers to set the duration of volume change according to specific needs, such as 500 milliseconds, 1 second, etc. This allows the speed of volume change to be adjusted according to different scenarios to meet different user experience requirements. Third, by checking and clearing old animation instances before creating new attribute animations, memory leaks are prevented. This not only improves the performance of the application, but also extends the battery life of the device. Fourth, the volume gradient logic is encapsulated in the attribute animation, making the code more modular and easy to maintain. If you need to modify or expand the function in the future, you only need to adjust the relevant parts without affecting the overall architecture. In summary, the method proposed in this application controls the sound gradient of video or audio during playback through attribute animation, which not only improves the user experience, but also enhances the performance and stability of the application. By accurately controlling the specific duration and change rate of the volume change, the volume gradient effect is more natural and smooth, thus providing users with a more comfortable and immersive audio-visual experience.
