Normally, the size or proportion of the main screen window 302 in the VR scene matches the display screen of the traditional video playback terminal.

FIG. 4 is a schematic flowchart of a method for previewing a video based on a VR scene provided by an embodiment of the present application. The method can be applied to the VR device shown in FIG. 2 and mainly includes the following steps.

Step S401: In response to an instruction to open a preview window input by a user, draw a preview window in a virtual space other than the main screen window, where the main screen window is used to play the main video.

The embodiment of the present application does not specifically limit the triggering form of the instruction to open the preview window. For example, the user can trigger the trigger through a touch screen, a button on a VR handle, a visual focus in a VR scene, or the like.

5a is a schematic diagram of a video preview based on a VR scene provided by an embodiment of the present application. Under normal circumstances, a user watches a video playback screen through the main screen window 501. The preview window 502 is drawn in the virtual space 301 other than the main screen window 501 .

Since the preview window 502 is displayed in the virtual space 301 and will not block the main screen window 501, the preview window 502 can be set larger, for example, the same size as the main screen window 501, so that the user can use the preview window 502 Get the same movie viewing experience as the home screen window 501 . In addition, in the VR three-dimensional space, the preview window 502 and the main screen window 501 can be set horizontally, so that the user can shake his head left and right to switch the visual focus between the main screen window 501 and the preview window 502, as shown in FIG. 5a.

It should be pointed out that the embodiment of the present application does not limit the size and position of the preview window 502 . Those skilled in the art can set the preview window 502 at other positions or other sizes of the main screen window 501 according to actual needs. For example, in Figure 5b, in the VR three-dimensional space, the preview window 502 and the main screen window 501 are vertically arranged, and the user can switch the focus of the verse between the main screen window 501 and the preview window 502 by raising or lowering the head; in Figure 5c , the size of the preview window 502 is different from that of the main screen window 501 , and the preview window 502 is located at the upper right of the main screen window 501 . Of course, those skilled in the art can set the preview window 502 at other positions or other sizes of the main screen window 501 according to actual needs, which should all fall within the protection scope of the present application.

Step S402: Play the preview video of the main video in the preview window.

After the preview window is drawn, the preview video of the main video is played in the preview window. When the user watches the preview video image, it will not affect the video image in the main screen window.

In the embodiment of the present application, the preview window is displayed through the virtual space in the VR scene, and the preview window will not block the main screen window, thereby improving user experience.

In the embodiment of the present application, after the preview window is opened, the preview video in the preview window is kept synchronized with the main video by default. However, the playback mode of the preview video in the preview window can be adjusted accordingly according to the user's control, for example, fast forward, rewind, pause, turn on the audio of the preview window, switch the resolution of the preview video in the preview window, switch the playback of the preview video speed etc. Among them, after the audio in the preview window is turned on, the audio in the main screen window needs to be turned off synchronously. The following describes in detail with reference to specific embodiments.

FIG. 6 is a schematic flowchart of another VR scene-based video preview method provided by an embodiment of the present application. As shown in FIG. 6 , the method mainly includes the following steps.

Step S601: In response to an instruction to open a preview window input by a user, a preview window is drawn in a virtual space other than the main screen window.

In this embodiment of the present application, when a user watches a video based on a VR scene, a preview window can be triggered to open. The triggering manner may be a touch screen, a button on a VR handle, or a visual focus in a VR scene, etc., which is not limited in this embodiment of the present application.

After the VR device receives the instruction to open the preview window, in response to the instruction to open the preview window input by the user, it draws the preview window in the virtual space other than the main screen window, as shown in Figures 5a-5c.

Step S602: In the preview window, start playing the preview video from a position of a first time stamp, where the first time stamp is the current time stamp of the main video.

The time stamp is a time stamp in the audio or video, and the playback position of the video can be accurately located by the time stamp, for example, the playback of the preview video starts from the 35th minute and 20th second.

It can be understood that the main video and the preview video are the same video resource, then when the time stamps of the main video and the preview video are the same, the corresponding playback pictures are the same. Start playback so that the preview video and the main video are in sync.

After opening the preview window, the preview video is played from the current timestamp of the main video. That is, by default, the preview video and the main video keep playing in sync.

Step S603: Control the preview window to obtain the user operation focus.

It can be understood that if the preview window obtains the user operation focus, the controls in the preview window are activated, and the user can input corresponding control commands in the preview window; in the same principle, if the main screen window obtains the user operation focus, the controls in the main screen window will be activated. is activated, the user can enter the corresponding control commands in the main screen window.

FIG. 7 is a schematic diagram of another VR scene-based video preview provided by an embodiment of the present application. FIG. 7 shows a main screen window 701 and a preview window 702. In the preview window 702, there is a progress bar 703, and “Resolution Cut” ”, “Home screen playback”, “Cancel preview”, “Turn on audio” and other controls. To activate the controls in the preview window 702, it is first necessary to control the preview window 702 to obtain the user operation focus. After the preview window 702 obtains the user's operation focus, the user can input relevant control instructions by clicking or sliding the relevant controls. For example, fast forward, rewind, pause, turn on the audio of the preview window, switch the resolution of the preview video in the preview window, switch the playback speed of the preview video, etc. A detailed description will be given below.

Step S604: Determine whether a preview audio turn-on or turn-off instruction is received.

In this embodiment of the present application, since the main screen window and the preview window are equivalent to two independent windows, the audio can be selected to keep synchronization with the main video in the main screen window, or with the preview video in the preview window according to the needs of the user. .

If a preview audio on or off instruction is received, go to step S605; otherwise, go to step S606.

Step S605: Turn on or off the audio corresponding to the preview video, and turn off or turn on the audio corresponding to the main video in the main screen window.

For example, if a preview audio turn-on instruction is received, the audio corresponding to the preview video is turned on, and the audio corresponding to the main video in the main screen window is turned off; if a preview audio turn-off command is received, the audio corresponding to the preview video is turned off, Turn on the audio corresponding to the main video in the main screen window.

As shown in FIG. 7 , the user may click the “Turn on audio” control in the preview window 502 to input an instruction to turn on or turn off the preview audio, that is, to turn on or off the preview audio.

Step S606: Determine whether a fast-forward or fast-rewind command is received.

If the VR device has a touch screen, the user can swipe left or right or drag the progress bar on the touch screen with a finger to input fast-forward or fast-rewind commands. For example, the user inputs a fast-forward command by sliding the preview window to the right or dragging the progress bar in the preview window to the right; the user inputs a fast-rewinding command by sliding the preview window to the left or dragging the progress bar in the preview window to the left.

Of course, the user can also trigger the fast-forward or fast-rewind instruction in other manners, which will not be repeated here.

If a fast-forward or fast-rewind instruction is received, go to step S607; otherwise, go to step S608.

Step S607: Play the preview video from a second time stamp, where the second time stamp is the time stamp of the preview video corresponding to the fast-forward or fast-rewind command.

When the user slides or drags the progress bar left and right in the preview window, the time stamp corresponding to the position of the progress bar after the left and right sliding displacement or dragging the progress bar is recorded in real time, so that the playback position of the preview video can be located by the time stamp. For example, if the user drags the progress bar to the right to 30 minutes and 12 seconds, the preview video in the preview window starts to play from the 30th minute and 12 seconds. The video duration corresponding to the sliding distance is 2 minutes and 02 seconds, and the preview video in the preview window rewinds to 29 minutes and 10 seconds to start playing. That is to say, as the user slides or drags the progress bar left and right, the playback screen of the preview video changes in real time, which always corresponds to the left and right sliding displacement of the user or the drag position of the progress bar.

Among them, if the audio of the preview video is turned on when the user slides the screen left and right or drags the progress bar, discontinuous audio signals will be generated, which affects the user experience. In this embodiment of the present application, when the user slides the screen left and right or drags the progress bar, the audio of the preview video is turned off. That is, after receiving the fast-forward or fast-rewind instruction, it is determined whether the audio of the preview video is turned on, and if the audio of the preview video is turned on, the audio of the preview video needs to be turned off.

Step S608: Determine whether an end fast-forward or fast-rewind command is received.

In an optional embodiment, when the user stops triggering the preview window, the VR device receives an instruction to end fast-forward or fast-rewind. Also taking the touch screen as an example, when the user slides or drags the progress bar on the touch screen with his finger, the user lifts his finger on the touch screen, and the VR device receives an instruction to end fast forward or fast rewind.

If the VR device receives the end fast-forward or fast-rewind instruction, it goes to step S609; otherwise, returns to step S606, and continues to switch the video playback screen in the preview window according to the fast-forward or fast-rewind instruction.

Step S609: Start playing the preview video from a third time stamp, where the third time stamp is the time stamp of the preview video when the fast-forward or fast-rewind command ends.

If the VR device receives an end fast-forward or fast-rewind command, it starts playing from the position of the preview video when the fast-forward or fast-rewind command ends. For example, when the user drags the progress bar to the 22nd minute and 15th second, stops dragging and lifts the finger from the touch screen, the preview video starts to play from the 22nd minute and 15th second.

It should be noted that, in this embodiment of the present application, after the user stops triggering the preview window, the preview window still maintains the preview state. On the contrary, in the embodiment shown in FIG. 1a and FIG. 1b, after the user stops triggering the main screen window, the preview window disappears, the main screen window starts playing from the position where the progress bar is, and the preview mode ends. In other words, when performing fast-rewind or fast-forward preview in this embodiment of the present application, the user's finger does not need to always trigger the fast-forward or fast-rewind button or press the touch screen all the time. The preview window still maintains the playback state of the preview video.

Step S610: Determine whether a resolution switching instruction is received.

It can be understood that, in order to save resources, the preview video in the preview window does not need to have a very high resolution. Generally, the resolution of the preview video is set to be lower than the resolution of the main video.

However, the resolution of the preview video can also be adjusted accordingly according to the user's needs. As shown in FIG. 7 , there is a “Resolution Cut” control in the preview window 702, and the user can switch the preview video resolution by clicking the “Resolution Cut” control, for example, the resolution can be switched to 352x288, 720x576, 1920x1080 Wait.

If the VR device receives the resolution switching instruction, go to step S611, otherwise go to step S612.

Step S611: Switch the resolution of the preview video.

For example, the current resolution of the preview video is 720x576, and after receiving the resolution switching instruction, the resolution is adjusted to 352x288. Of course, the size of the specific resolution can be set and selected by users according to their own needs.

Step S612: Determine whether a playback speed switching instruction is received.

The playback speed refers to the speed at which the preview video is played, for example, it can be played at 1.5 times or 2.0 times the normal playback speed, so as to facilitate the user to preview quickly. Of course, it can also be set to 0.5 times, 0.8 times, etc. according to the special needs of the user, which is not specifically limited in the embodiment of the present application.

Step S613: Switch the playback speed of the preview video.

For example, the current playback speed of the preview video is 1.0 times the speed, that is, the preview video is played at the normal playback speed. After receiving the playback speed switching instruction, adjust the playback speed to 1.5 times the speed. Of course, users can set and select the specific speed according to their own needs.

Step S614: Determine whether an instruction to cancel the preview window is received.

After the user completes the preview of the video, the preview window can be canceled by inputting an instruction to cancel the preview window, and the normal playback mode can be restored. As shown in FIG. 7 , a “cancel preview” control is provided in the preview window 702 , and the user can cancel the preview window by clicking the “cancel preview” control.

If an instruction to cancel the preview window is received, go to step S617; otherwise, go to step S615.

It should be pointed out that, in the embodiment of the present application, after the preview window is canceled, the main screen window will not be affected, and the main screen window will still maintain the playback state before the preview. For example, when the preview window is canceled, the main video is played to 20 minutes and 13 seconds, and the preview video is played to 30 minutes and 25 seconds. After the preview window is canceled, the main video continues to be played from the 20 minutes and 13 seconds. That is to say, in the embodiment of the present application, after the preview mode ends, there is no need for the user to return the main video to the state before the preview by manually adjusting the progress bar or sliding the screen.

On the contrary, in the solutions shown in Figure 1a and Figure 1b, after the preview mode ends, the main screen window starts playing from the position where the current progress bar is by default. If the user wants to return to the position before the preview, he needs to drag the progress again. Bar or swipe the screen to adjust, the user experience is poor.

Step S615: Determine whether an instruction to start playing the main screen is received.

If the user needs to switch from the position of the previewed video to playing in the main screen window after completing the video preview, he or she can enter an instruction to start playing the main screen. As shown in FIG. 7 , the preview window 702 is provided with a “play on home screen” control, the user can cancel the preview window by clicking on the “play on home screen” control, and switch the playback state of the preview video to play on the home screen window.

Step S616: Control the main video in the main screen window to start playing from a fourth time stamp, where the fourth time stamp is the time stamp of the preview video when the preview window is closed.

For example, when receiving an instruction to start playing the main screen, the main video is played to the 20th minute and 13 seconds, and the preview video is played to 30 minutes and 25 seconds. After the preview window is canceled, the main video jumps to the 30th minute and 25 seconds to start playing.

Step S617: Close the preview window.

After receiving an instruction to cancel the preview window, or receiving an instruction to start playing the main screen, the preview window needs to be closed, and only the main screen window is retained to play the main video.

Step S618: Control the main screen window to obtain the user operation focus.

After the preview window is canceled, the main screen window regains the user's operation focus, and the user can input corresponding control instructions in the main screen window.

It should be pointed out that the technical solution shown in FIG. 6 is only a specific implementation manner listed in the embodiment of the present application, and should not be regarded as a limitation of the protection scope of the present application. For example, those skilled in the art can adjust the timing relationship in FIG. 6 according to actual needs, first determine "whether a fast-forward or fast-rewind command is received", and then determine "whether a preview audio on or off command is received"; "Whether a resolution switching instruction is received", and then determine "whether a playback speed switching instruction is received", etc. Alternatively, the above steps are deleted according to actual needs, and only some functions in the above solution are implemented.

To sum up, the technical solutions provided by the embodiments of the present application have the following advantages:

1. The preview window is displayed through the virtual space in the VR scene. The preview window will not block the main screen window and will not affect the normal viewing of the video in the main screen window.

2. Since there are many virtual spaces in the VR scene, the preview window can be set to be large enough to facilitate users to watch the preview video;

3. Since the main screen window and the preview window are two independent windows, users can slide or drag the progress bar to adjust at will when fast-forwarding or rewinding in the preview window, without having to keep the trigger state all the time, which is convenient for precise fine-tuning;

4. After the preview is over, cancel the preview window, and the user can choose to continue playing according to the playback time of the main video, so as not to manually adjust the viewing time before returning to the preview; in addition, the user can also choose to jump to the playback time of the preview video Start playing;

5. The user can start the audio of the preview window and mute the main screen window at the same time, so that the user can hear the preview audio while watching the preview video.

FIG. 8 is a block diagram of a software structure of an electronic device according to an embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, an application layer, an application framework layer, an Android runtime (Android runtime) and a system library, and a kernel layer.

The application layer can include a series of application packages.

As shown in Figure 8, the application package can include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and so on.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 8, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, take screenshots, etc.

Content providers are used to store and retrieve data and make these data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. View systems can be used to build applications. A display interface can consist of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide the communication function of the electronic device. For example, the management of call status (including connecting, hanging up, etc.).

The resource manager provides various resources for the application, such as localization strings, icons, pictures, layout files, video files and so on.

The notification manager enables applications to display notification information in the status bar, which can be used to convey notification-type messages, and can disappear automatically after a brief pause without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also display notifications in the status bar at the top of the system in the form of graphs or scroll bar text, such as notifications of applications running in the background, and notifications on the screen in the form of dialog windows. For example, text information is prompted in the status bar, a prompt sound is issued, the electronic device vibrates, and the indicator light flashes.

Android Runtime includes core libraries and a virtual machine. Android runtime is responsible for scheduling and management of the Android system.

The core library consists of two parts: one is the function functions that the java language needs to call, and the other is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, safety and exception management, and garbage collection.

A system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The Surface Manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display drivers, camera drivers, audio drivers, and sensor drivers.

The video application in the application framework layer may be a VR video application, and the video preview solution involved in the above embodiments may be implemented based on the VR video application.

However, there are many types of VR video applications. If each VR video application implements its own video preview solution, the workload is large, and the uniform video preview style cannot be guaranteed, which affects the user experience.

Software Development Kit (SDK) is a collection of development tools for building application software for a specific software package, software framework, hardware platform, operating system, etc. It can simply provide application programs for a programming language Some files for the interface API.
