Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a method for displaying bullet screens and related devices. Background Art

[0002] Bullet screen is a form of information exchange that scrolls and displays the audience's comments and other content on the display screen during video playback. As a form of information exchange, bullet screen meets people's information exchange needs when watching videos.

[0003] There are some applications on the market that support controlling the display of barrage (including system applications or third-party applications). When an application that supports controlling the display of barrage is installed on a device, the device can rely on these applications that support the display of barrage to display barrage in response to the user's settings for the display effect of barrage (such as display area, display speed, font size, etc.)

[0004] However, in some scenarios, for example, in the device playback scenario, when the device uses an application that does not support the control of the barrage display to play content containing barrage data, or in the screen projection scenario, when the device is the receiving end of the screen projection content (including barrage data), and the device is displaying the screen projection content, the user cannot set the barrage display effect on the device, and accordingly, the device cannot respond to the user's setting of the barrage display effect and display the barrage according to the display effect expected by the user. Therefore, the current device's display of barrage is not intelligent enough, and the user experience is poor. Summary of the invention

[0005] The present application provides a method and related device for displaying barrage, in order to improve the intelligence of the device in displaying barrage and improve the user experience.

[0006] The first aspect provides a method for displaying barrage, which can be executed by a first device, or the method can also be executed by a component configured in the first device (such as a chip, a chip system, etc.), or it can also be implemented by a logic module or software that can realize all or part of the functions of the first device, and the present application does not limit this.

[0007] Exemplarily, the method includes: displaying barrage based on a first display effect; in response to user operation, displaying a setting interface for the barrage display effect, the setting interface being provided by an operating system or system application of the first device; and displaying barrage based on a second display effect set by the user on the setting interface.

[0008] Based on the above scheme, the operating system or system application of the device has a service for providing control over the barrage display effect, so that the device can provide the user with a setting interface for displaying the barrage display effect, and then can display the barrage according to the barrage display effect set by the user on the setting interface. Therefore, the intelligence of the device's display of the barrage can be improved, thereby improving the user experience.

[0009] In combination with the first aspect, in some possible implementations, the user operation is an operation on a control, and the control is displayed when the barrage control service is turned on. The barrage control service is a service for providing control over the barrage display effect.

[0010] In combination with the first aspect, in some possible implementations, before displaying the barrage based on the first display effect, the method further includes: acquiring barrage data for displaying the barrage.

[0011] In combination with the first aspect, in some possible implementations, obtaining barrage data for displaying barrage includes: receiving the address of barrage data from a second device, where the second device is a device that initiates screen projection, and the second device has established a screen projection connection with the first device; and obtaining barrage data based on the address.

[0012] In the screen projection scenario, the second device initiates screen projection to the first device, and the first device establishes a screen projection connection with the second device. The second device, as the source of data, can send the address of the barrage data to the first device. Correspondingly, the first device can receive the address of the barrage data from the second device. After receiving the address of the barrage data, the first device can obtain the barrage data based on the address, for example, download the barrage data based on the address.

[0013] In combination with the first aspect, in some possible implementations, obtaining barrage data for displaying barrage includes: receiving barrage data from a second device, where the second device is a device that initiates screen projection, and the second device establishes a screen projection connection with the first device.

[0014] In the screen projection scenario, the second device initiates screen projection to the first device, and the first device establishes a screen projection connection with the second device. The second device, as the source of data, can send barrage data to the first device. Correspondingly, the first device can receive the barrage data from the second device, so that the first device obtains the barrage data.

[0015] In combination with the first aspect, in some possible implementations, obtaining barrage data for displaying barrage includes: receiving an address of the barrage data from a server, where the server is also used to provide playback resources; and obtaining the barrage data based on the address.

[0016] In the local playback scenario, the first device can obtain the address of the playback resource and the barrage data from the server for providing the playback resource, and then download the playback resource and the barrage data based on the address, so that the first device obtains the barrage data.

[0017] The second aspect provides a method for displaying barrage, which can be executed by a second device, or the method can also be executed by a component configured in the second device (such as a chip, a chip system, etc.), or it can also be implemented by a logic module or software that can realize all or part of the functions of the second device. This application is not limited to this.

[0018] Exemplarily, the method includes: establishing a screen projection connection with a first device; obtaining barrage data when a protocol based on which the screen projection connection established with the first device is a mirroring screen projection protocol; and sending the barrage data to the first device.

[0019] Based on the above scheme, in the screen projection scenario, the second device that initiates the screen projection can obtain the barrage data and send the barrage data to the first device, so that the first device can display the barrage based on the barrage data and according to the barrage display effect set by the user. This can avoid the problem that the first device cannot control the barrage display effect due to the second device directly sending the recorded video screen including the barrage to the first device. This can improve the intelligence of the device's display of the barrage, thereby improving the user experience.

[0020] In combination with the second aspect, in some possible implementations, obtaining the barrage data includes: playing the projected content; screen recording the projected content to obtain a video screen; and separating the barrage data from the video screen.

[0021] A third aspect provides a device, which can be used to implement the method in the first aspect and any possible implementation of the first aspect, or can be used to implement the method in the second aspect and any possible implementation of the second aspect. The device includes a corresponding module for executing the above method. The module included in the device can be implemented by software and / or hardware.

[0022] A fourth aspect provides a device, the device comprising at least one processor and at least one communication interface. The processor is coupled to the communication interface and can be used to execute a program to implement the method for displaying a bullet screen in the first aspect and any possible implementation of the first aspect, or to implement the method for displaying a bullet screen in the second aspect and any possible implementation of the second aspect.

[0023] Optionally, the device further includes a memory, and the processor is coupled to the memory.

[0024] The fifth aspect provides a chip system, which includes at least one processor for supporting the implementation of the functions involved in the above-mentioned first aspect and any possible implementation method of the first aspect, or for supporting the implementation of the functions involved in the above-mentioned second aspect and any possible implementation method of the second aspect, for example, processing the data involved in the above-mentioned method, etc.

[0025] In one possible design, the chip system also includes a memory, which is used to store programs, instructions, or data, etc. The memory is located inside or outside the processor.

[0026] The chip system may be composed of the chip, or may include the chip and other discrete devices.

[0027] The sixth aspect provides a readable storage medium, on which a program (also referred to as code, or instruction) is stored. When the program is run by a device, the method in the above-mentioned first aspect and any possible implementation of the first aspect is executed, or the method in the above-mentioned second aspect and any possible implementation of the second aspect is executed.

[0028] The seventh aspect provides a program product, which includes: a program (also referred to as code, or instruction), which, when executed, causes the method in the above-mentioned first aspect and any possible implementation of the first aspect to be executed, or causes the above-mentioned second aspect and any possible implementation of the second aspect to be executed.

[0039] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0040] First, in the embodiments of the present application, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, the words "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first device and the second device are only used to distinguish different devices, and their order is not limited. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0041] Second, in the embodiments of the present application, "and / or" describes the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B may be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship, but does not exclude the situation where the associated objects before and after are in an "and" relationship. The specific meaning can be understood in conjunction with the context.

[0042] Third, in the present application, "when...", "in the case of...", "if" and "if" all mean that the device will take corresponding actions under certain objective circumstances, but do not limit the time, nor do they require that the device must have a judgment action when it is implemented, nor do they mean that there are other limitations.

[0043] Fourth, in this application, "send" and "receive" refer to the direction of transmission of information, messages, signals or messages.

[0044] For example, “the address at which the first receiving device receives the barrage data from the second device” can be understood as the destination end of the address of the barrage data is the first device, and the source end is the second device.

[0045] For another example, “the second device sends barrage data to the first device” can be understood as the source of the barrage data is the second device, and the destination is the first device.

[0046] Barrage is the scrolling display of audience comments and other content on the display screen during video playback. As a form of information interaction, barrage meets people's information exchange needs when watching videos. There are currently some applications on the market that support controlling the display of barrage (including system applications or third-party applications), such as but not limited to some video playback applications, audio playback applications, and e-book applications. If an application that supports controlling the display of barrage is installed on the device, the device can rely on these applications that support the display of barrage to display barrage in response to the user's settings for the display effect of barrage (such as display area, display speed, font size, etc.).

[0047] However, in some scenarios, for example, in the device playback scenario, when the device uses an application that does not support the control of the barrage display to play content containing barrage data, or in the screen projection scenario, when the device is the receiving end of the screen projection content (including barrage data), and the device is displaying the screen projection content, the user cannot set the barrage display effect on the device, and accordingly, the device cannot respond to the user's setting of the barrage display effect and display the barrage according to the display effect expected by the user. Therefore, the current device's display of barrage is not intelligent enough, and the user experience is poor.

[0048] In order to solve the above problems, the present application provides a method and related devices for displaying barrage, by deploying a service for providing control of barrage display effects in the operating system of the device, or encapsulating the service for controlling the barrage display effects as a system application of the device, so that the device can provide a setting interface for displaying barrage display effects for the user, and then can display the barrage according to the barrage display effects set by the user on the setting interface. Therefore, the intelligence of the device's display of barrage can be improved, thereby improving the user experience.

System applications may be understood as some applications that come with the system, such as camera, gallery, calendar, call, map, Bluetooth, video, and music applications. Third-party applications may be understood as non-system applications that can be downloaded and installed from an application store or the like.

[0096] The core library can include two parts: one part is the function that needs to be called by the Java language, and the other part is the core library of the Android operating system.

[0100] In the embodiments of the present application, Figure 2 or Figure 3 As shown, the device may include a barrage control module, an image acquisition module and a barrage separation module, so that the device has the ability to implement the method for displaying barrage provided in the present application.

[0101] It should be understood that Figure 1 , Figure 2 and Figure 3 This is only an example and should not limit the embodiments of the present application.

[0102] Figure 4 It is a schematic flowchart of a method for displaying barrage provided in an embodiment of the present application.

[0103] like Figure 4 As shown, method 400 may include steps 410 to 430. The steps of method 400 may be performed by the first device, or the method 400 may be performed by a component (such as a chip or a chip system, etc.) configured in the first device, or may be implemented by a logic module or software that can implement all or part of the functions of the first device, which is not limited in the present embodiment of the application. The first device may have Figure 1 , Figure 2 or Figure 3 The structure shown in the embodiment of the present application is not limited to this. Figure 4 Detailed description of each step in.

[0104] In step 410, the bullet screen is displayed based on the first display effect.

[0105] The first device can display the barrage based on the first display effect.

[0106] In one example, in a local playback scenario, the first device uses an application that does not support the control of barrage display to play content containing barrage data, and the first display effect can be the default barrage display effect played by the application that does not support the control of barrage display.

[0107] In another example, in a screen projection scenario, a first device establishes a screen projection connection with a second device, the second device is the device initiating the screen projection, that is, the second device is the source of the screen projection content, and the first device is the receiving end of the screen projection content (including bullet screen data). The first device can display the bullet screen based on the first display effect, and the first display effect can be the bullet screen display effect set by the user on the second device, or the first display effect can also be the default bullet screen display effect on the second device. In other words, the bullet screen display effect on the first device depends on the bullet screen display effect on the second device.

[0108] In step 420, in response to the user's operation, a setting interface for the barrage display effect is displayed, and the setting interface is provided by the operating system or system application of the first device.

[0109] The first device can display a setting interface for the barrage display effect in response to the user's operation, so that the user can set the barrage display effect that the user wants the first device to display through the setting interface according to personal needs.

[0110] The setting interface is provided by the operating system or system application of the first device. For example, a possible implementation is as follows: Figure 2 or Figure 3As shown, a bullet screen control module may be deployed in the operating system of the first device, and the bullet screen control module may be used to provide services including but not limited to bullet screen control services. Another possible implementation is to encapsulate the bullet screen control module as a system application of the first device to provide users with bullet screen control services. The setting interface is an interface provided by the bullet screen control service for interacting with the user.

[0111] In a possible implementation, the user operation is an operation on a control, and the control is displayed when a bullet screen control service is turned on. The bullet screen control service is a service for providing control over the bullet screen display effect.

[0112] It is understandable that the user can operate the control to call out the setting interface of the barrage display effect, that is, the control can be used to call out the setting interface.

[0113] As an example but not limitation, in some possible implementations, the first device may provide a control for turning on or off the bullet screen control service in a side toolbar (such as a side toolbar of a smart screen) or a drop-down toolbar (such as a drop-down toolbar of a mobile phone or tablet) or a control center (for ease of description, the control is referred to as a first control); in some other possible implementations, the first device may provide the first control in a service setting interface. This allows the user to turn on or off the bullet screen control service at any time by operating the first control as needed.

[0114] It is understandable that the above-mentioned user operation may be that the user operates the first control to start the bullet screen control service.

[0115] Figure 5 It is a schematic diagram of the first control provided in an embodiment of the present application.

[0116] like Figure 5 As shown, the control labeled with the words "bullet screen control" may be an example of the first control. Figure 5 In a), the style of the control marked with the words "bullet screen control" can indicate that the bullet screen control service is closed. The user can click the control marked with the words "bullet screen control" to turn on the bullet screen control service and switch the control to the following state: Figure 5 The style shown in b) of FIG. 1 may indicate that the bullet screen control service is turned on. It is understandable that Figure 5 This is only an example and should not be construed as limiting the present application.

[0117] When the bullet screen control service is turned on, the first device can display the above-mentioned control (for the convenience of description, the control is recorded as the second control), and the user can operate the second control to call out the setting interface of the above-mentioned bullet screen display effect.

[0118] Figure 6 It is a schematic diagram of the second control provided in an embodiment of the present application.

[0119] like Figure 6 The second control shown in a) of FIG. 1 may be operated by the user, for example, including but not limited to clicking the second control to call up a Figure 6 The setting interface of the barrage display effect shown in b).

[0120] In some possible implementations, the setting interface of the bullet screen display effect may include but is not limited to options for setting the display area, display speed, font size, font color, opacity, removing occlusion, removing duplication, removing advertisements, automatically avoiding portraits, and intelligent spoiler prevention. This application does not impose any restrictions on this. Figure 6 In b), options for setting the opacity, display speed, font size, display area, automatic avoidance of portraits, and intelligent spoiler prevention are shown by way of example. It is understandable that Figure 6 This is only an example and should not limit the present application in any way.

[0121] In one possible implementation, as an example but not a limitation, the priority of the bullet screen control service provided by the operating system of the first device is higher than the ability of third-party applications and system applications to control the display of bullet screens. For example, a video playback application installed on the first device has the ability to control the display of bullet screens. When the first device uses the video playback application to play a video resource with bullet screen data, when the bullet screen control service of the first device is turned on, the first device can display the bullet screen based on the bullet screen display effect set by the user on the setting interface of the bullet screen display effect provided by the bullet screen control service of the operating system of the first device, and the setting of the bullet screen display effect in the video playback application can be ignored.

[0122] In step 430, the bullet screen is displayed based on the second display effect set by the user on the setting interface.

[0123] Exemplarily, the user operates on the setting interface of the bullet screen display effect, and the first device can display the bullet screen with the second display effect in response to the user's operation. It is understandable that the second display effect is different from the first display effect, and the difference between the second display effect and the first display effect can be reflected in at least one of the following differences, including but not limited to the display area, display speed, font size, font color, opacity, removal of occlusion, removal of duplication, removal of advertisements, automatic avoidance of portraits, and intelligent spoiler prevention of the bullet screen, and this application does not make any limitation on this.

[0124] In a possible implementation, before displaying the barrage based on the first display effect, method 400 further includes: acquiring barrage data for displaying the barrage.

[0125] It is understandable that the premise that the first device displays the bullet screen based on the first display effect includes that the first device needs to obtain bullet screen data for displaying the bullet screen. The bullet screen data may be data having a certain encoding format, and the encoding format may include but is not limited to a file format, a real-time transport protocol (RTP) format, a video container format (such as MP4 format, etc.) or a transport stream (TS) format, etc., and this application does not impose any limitation on this.

[0126] In some embodiments, obtaining barrage data for displaying barrage includes: receiving an address of barrage data from a second device, where the second device is a device that initiates screen projection, and the second device has established a screen projection connection with the first device; and obtaining barrage data based on the address.

[0127] In the screen projection scenario, the second device initiates screen projection to the first device, and the first device establishes a screen projection connection with the second device. The second device, as the source of data, can send the address of the barrage data to the first device. Correspondingly, the first device can receive the address of the barrage data from the second device. After receiving the address of the barrage data, the first device can obtain the barrage data based on the address, for example, download the barrage data based on the address.

[0128] In other embodiments, obtaining barrage data for displaying barrage includes: receiving barrage data from a second device, where the second device is a device that initiates screen projection, and the second device establishes a screen projection connection with the first device.

[0129] In the screen projection scenario, the second device initiates screen projection to the first device, and the first device establishes a screen projection connection with the second device. The second device, as the source of data, can send barrage data to the first device. Correspondingly, the first device can receive the barrage data from the second device, so that the first device obtains the barrage data.

[0130] In some other embodiments, obtaining barrage data for displaying barrage includes: receiving an address of the barrage data from a server, where the server is also used to provide playback resources; and obtaining the barrage data based on the address.

[0131] It is understandable that the playback resources may include but are not limited to video resources, audio resources, and e-book resources.

[0132] In the local playback scenario, the first device can obtain the address of the playback resource and the address of the barrage data from the server used to provide the playback resource, and then download the playback resource based on the address of the playback resource, and download the barrage data based on the address of the barrage data, so that the first device obtains the barrage data.

[0133] Based on the above scheme, the operating system of the device has a service for providing control of the display effect of the bullet screen, so that the device can provide the user with a setting interface for displaying the display effect of the bullet screen, and then display the bullet screen according to the bullet screen display effect set by the user on the setting interface. Therefore, the intelligence of the device's display of the bullet screen can be improved, thereby improving the user experience. Furthermore, the method for displaying the bullet screen is applicable to local playback scenarios and screen projection scenarios, etc., does not depend on the provider of the bullet screen data, and has good universality.

[0134] Figure 7 It is another schematic flowchart of the method for displaying barrage provided in an embodiment of the present application.

[0135] like Figure 7 As shown, method 700 may include steps 710 to 730. The steps of method 700 may be performed by the second device, or the method 700 may be performed by a component (such as a chip or a chip system, etc.) configured in the second device, or may be implemented by a logic module or software that can implement all or part of the functions of the second device, which is not limited in the present embodiment. The second device may have the following features: Figure 1 , Figure 2 or Figure 3 The structure shown in the embodiment of the present application is not limited to this. Figure 7 Detailed description of each step in.

[0136] In step 710, a screen projection connection is established with the first device.

[0137] As an example and not a limitation, the second device and the first device may support the mirroring screen projection protocol and / or the digital living network alliance (DLNA) screen projection protocol, or the second device and the first device may also support shared playback over a local area network, which is not limited in this application. In an embodiment of the present application, sharing playback between the second device and the first device via a local area network can also be classified as a screen projection scenario between the first device and the second device. Among them, the mirroring screen projection protocol may include but is not limited to the Miracast screen projection protocol or the AirPlay screen projection protocol.

[0138] In the screen projection scenario, the second device can initiate screen projection to the first device in response to the user's operation and establish a screen projection connection with the first device.

[0139] In step 720, when the protocol based on which the screen projection connection established with the first device is a mirroring screen projection protocol, the barrage data is obtained.

[0140] The second device establishes a screen projection connection with the first device, and the second device can learn the protocol based on which the established screen projection connection is based. When the protocol based on which the screen projection connection established with the first device is a mirror screen projection protocol, the second device can first obtain the barrage data before sending the barrage data to the first device.

[0141] In a possible implementation, obtaining the barrage data includes: playing the projected content; screen recording the projected content to obtain a video screen; and separating the barrage data from the video screen.

[0142] It is understandable that the screen projection content may include but is not limited to video resources, audio resources or e-book resources containing barrage data. Figure 2 or Figure 3 As shown, an image acquisition module and a barrage separation module may be deployed in the operating system of the second device. When the protocol based on which the screen projection connection established with the first device is a mirror screen projection protocol, the second device can play the projection content and perform screen recording of the projection content based on the image acquisition module to obtain a video screen. Furthermore, the second device can separate the barrage data from the video screen based on the barrage separation module. For example, the second device can perform image recognition technology and / or layer separation technology on the video screen based on the barrage separation module to separate the barrage data from the video screen. This application does not impose any limitation on this.

[0143] In step 730, the bullet screen data is sent to the first device.

[0144] Exemplarily, after acquiring the barrage data, the second device may send the barrage data to the first device.

[0145] In some possible implementations, when the screen projection connection established with the first device is based on the DLNA screen projection protocol or the local area network shared playback protocol, the second device can directly send the address of the barrage data to the first device, so that the first device can obtain the barrage data based on the address of the barrage data. This application does not impose any limitations on this.

[0146] Based on the above scheme, in the mirror screen projection scenario, the second device that initiates the screen projection can obtain the barrage data and send the barrage data to the first device, so that the first device can display the barrage based on the barrage data and according to the barrage display effect set by the user. This can avoid the problem that the first device cannot control the barrage display effect due to the second device directly sending the recorded video screen including the barrage to the first device. This can improve the intelligence of the device's display of the barrage, thereby improving the user experience.

[0147] In order to better understand the method for displaying bullet comments provided by the present application, the following Figure 8 and Fig. 9 The method for displaying barrage provided in this application is further explained.

[0148] Figure 8 It is another schematic flowchart of the method for displaying barrage provided in an embodiment of the present application.

[0149] In step 810, the second device initiates screen projection in response to the user's operation; the first device negotiates screen projection with the second device and establishes a screen projection connection.

[0150] Exemplarily, the second device can initiate a screen projection connection request to the first device in response to the user's screen projection operation. The first device can respond to the request of the second device, and screen projection negotiation can be performed with the second device, and the first device and the second device establish a screen projection connection.

[0151] In step 820, when the protocol based on which the screen projection connection established with the first device is the mirroring screen projection protocol, the second device performs screen recording on the projection content to obtain a video image.

[0152] like Figure 2 or Figure 3 As shown, an image acquisition module can be deployed in the operating system of the second device. When the protocol based on which the screen projection connection established with the first device is a mirror projection protocol, the second device can play the projection content and perform screen recording of the projection content based on the image acquisition module to obtain a video screen.

[0153] In step 830, the second device separates the barrage data from the video screen to obtain the original playback resources and the barrage data.

[0154] The original playback resource may refer to a playback resource that does not include the bullet screen data. In this implementation, the original playback resource and the bullet screen data are stored in the same data file. If the second device directly sends the recorded video screen to the first device, the first device cannot control the display effect of the bullet screen. Therefore, the second device needs to separate the bullet screen data from the video screen.

[0155] like Figure 2 or Figure 3 As shown, a barrage separation module can be deployed in the operating system of the second device, and the second device can separate the barrage data from the video screen based on the barrage separation module. For example, the second device can perform image recognition technology and / or layer separation technology on the video screen based on the barrage separation module to separate the barrage data from the video screen.

[0156] In step 840, the second device sends the bullet screen data and the original playback resource to the first device. Correspondingly, the first device receives the bullet screen data and the original playback resource from the second device.

[0157] After separating the bullet screen data from the video screen, the second device can encode the bullet screen data and the original playback data respectively, and transmit them to the first device.

[0158] In step 850, the first device plays the original playback resource and displays the barrage based on the first display effect.

[0159] Exemplarily, the first device may start a player, decode and display the original playback resource, and create a surface view control to display the bullet screen based on the bullet screen data.

[0160] For a detailed description of the first device displaying the barrage based on the first display effect, please refer to the relevant description of step 410 in the above method 400. For the sake of brevity, it will not be repeated here.

[0161] In step 860, in response to the user's operation of calling up a setting interface for the barrage display effect, the first device displays the setting interface.

[0162] Exemplarily, the first device can create a view for controlling the display effect of the bullet screen on the surface view in response to the user's operation, that is, a setting interface for the display effect of the bullet screen, which includes but is not limited to setting options for controlling the display area, display speed, font size, font color, opacity, removing advertisements, removing occlusions, removing duplications, automatically avoiding portraits, and intelligent spoiler prevention for the bullet screen, so that the user can operate on the setting interface. When the user operates at least one option on the setting interface, the first device can adjust the surface view by setting the attribute value of the surface view in response to the user's operation, and generate a corresponding bullet screen control strategy, and a corresponding bullet screen display effect can be generated based on the generation of the corresponding bullet screen control strategy.

[0163] For a detailed description, please refer to the relevant description of step 420 in the above method 400, which will not be repeated here for the sake of brevity.

[0164] In step 870, the first device displays the barrage based on the second display effect set by the user on the setting interface.

[0165] It can be understood that each time the property value of the surface view is adjusted, the barrage can be displayed with the adjusted barrage display effect.

[0166] For a detailed description, please refer to the relevant description of step 430 in the above method 400, which will not be repeated here for the sake of brevity.

[0167] Fig. 9 This is another schematic flowchart of the method for displaying barrage provided in an embodiment of the present application.

[0168] In step 910, the second device initiates screen projection in response to the user's operation; the first device negotiates screen projection with the second device and establishes a screen projection connection.

[0169] For a detailed description, please refer to the relevant description of step 810 above, which will not be repeated here for the sake of brevity.

[0170] In step 920, when the protocol based on which the screen projection connection established with the first device is the DLNA screen projection protocol or the LAN shared playback protocol, the second device sends the address of the screen projection content to the first device, and the screen projection content includes the original playback resources and barrage data.

[0171] As mentioned above, the original playback resource may refer to a playback resource that does not include barrage data. In this implementation, the original playback resource and the barrage data are not stored in the same data file, and the address of the screen projection content includes the address of the original playback resource and the address of the barrage data.

[0172] When the screen projection connection established with the first device is based on the DLNA screen projection protocol or the LAN shared playback protocol, the second device can directly send the address of the original playback resource and the address of the barrage data to the first device, so that the first device can obtain the barrage data based on the address of the barrage data.

[0173] In step 930, the first device obtains the original playback resources and barrage data based on the address of the projected content.

[0174] The first device can obtain the barrage data based on the address of the barrage data, and obtain the original playback resource based on the address of the original playback resource.

[0175] In step 940, the first device plays the original playback resource and displays the barrage based on the first display effect.

[0176] For a detailed description, please refer to the relevant description of step 850 above, which will not be repeated here for the sake of brevity.

[0177] In step 950, in response to the user's operation of calling up a setting interface for the barrage display effect, the first device displays the setting interface.

[0178] For a detailed description, please refer to the relevant description of step 860 above, which will not be repeated here for the sake of brevity.

[0179] In step 960, the first device displays the barrage based on the second display effect set by the user on the setting interface.
