[0075] Figure 2 This is a flow chart of a video preview method provided in an embodiment of the present application. This embodiment is described with a terminal as the execution subject. Figure 2 , the embodiment comprises:

[0076] 201. The terminal determines a playback area for a target video to be played.

[0077] In the embodiment of the present application, the target video is a video that the user wants to preview. Optionally, the target video is a local video stored on the terminal. Optionally, the target video is an online video. The embodiment of the present application does not specifically limit the source of the target video.

[0078] 202. The terminal divides the playback area into multiple sub-playback areas.

[0079] In the embodiment of the present application, after the terminal divides the playback area, the obtained divided playback area includes multiple partitions, each partition is a sub-playback area, and the size of the sub-playback area is smaller than the size of the playback area.

[0080] 203. The terminal determines playback information of each sub-playback area based on the multiple sub-playback areas and the playback duration of the target video.

[0081] In the embodiment of the present application, the playback information refers to the start playback time and playback duration of the target video in the sub-playback area.

[0082] 204. The terminal obtains multiple sub-videos of the target video based on the playback information of each sub-playback area, where one sub-video corresponds to one sub-playback area.

[0083] In the embodiment of the present application, each sub-playback area corresponds to a decoder, and the decoder is used to decode the target video to obtain multiple sub-videos of the target video.

[0084] 205. The terminal plays the corresponding sub-video in each sub-playing area of ​​the playing area.

[0085] In an embodiment of the present application, a video preview method is provided. For a video that a user wants to preview quickly, before playing the video, the video is divided into multiple sub-videos according to the playing time, and then the corresponding sub-videos are played in each sub-playing area of ​​the playing area. Through the above method, the playing effect of playing multiple sub-videos of a video at the same time in the entire playing area is achieved, so that the user can quickly preview the complete content of a video, which greatly improves the efficiency of the user's video preview.

[0086] Figure 3 This is a flowchart of another video preview method provided by an embodiment of the present application. This embodiment is described with a terminal as the execution subject. Figure 3 , the embodiment comprises:

[0087] 301. In response to a user clicking operation on a target video to be played, the terminal displays a play area of ​​the target video.

[0088] In an embodiment of the present application, the terminal provides a video playback function. The user clicks on the target video he wants to preview on the terminal. The terminal responds to the click operation, starts the video playback function, obtains the video playback interface, and displays the playback area of ​​the target video on the video playback interface.

[0089] Optionally, the target video is a local video stored on the terminal, and a local video selection interface is displayed on the terminal. The user can select the target video for preview by clicking on the video he wants to preview. The terminal then responds to the click operation, obtains a video playback interface, and displays the playback area of ​​the target video on the video playback interface.

[0090] Optionally, the target video is an online video, and an online video selection interface is displayed on the terminal. The user can select the target video for preview by clicking on the video he wants to preview. In response to the click operation, the terminal sends a request to obtain the target video to the target server. The request carries the identifier of the target video and the identifier of the terminal. Based on the request, the target server sends the video resources of the target video to the terminal. The terminal receives the video resources of the target video and obtains a video playback interface, and displays the playback area of ​​the target video on the video playback interface.

[0091] It should be noted that in other embodiments, the terminal provides multiple videos on the acquired video playback interface, and the user can select a target video for preview by clicking on the video to be previewed. The embodiment of the present application does not specifically limit the method for selecting the target video.

[0092] In addition, in some embodiments, the target video is a segment video in a complete video. Specifically, after the user clicks on the first video that he wants to preview on the terminal, the terminal responds to the click operation, turns on the video playback function, obtains the video playback interface, and provides a segment selection operation for the first video on the video playback interface. The terminal detects the user's segment selection operation for the first video, and based on the segment selection operation, determines the second video, which is the target video. For example, the segment selection operation is implemented by the user's editing operation on an editable dialog box. The user enters the start time and end time of the segment video that he wants to preview in the editable dialog box to select the segment video. The embodiment of the present application does not limit the specific implementation method of the segment selection operation.

[0093] It should be noted that the embodiment of the present application does not limit whether the target video is a complete video or a fragment of a complete video.

[0094] 302. The terminal determines the number of sub-playback areas in response to the division operation on the playback area.

[0095] In the embodiment of the present application, after the terminal divides the playback area, the obtained divided playback area includes multiple partitions, each partition is a sub-playback area, and the size of the sub-playback area is smaller than the size of the playback area. The terminal detects the user's operation of dividing the playback area, and determines the number of sub-playback areas based on the division operation.

[0096] The following are two ways to implement the partitioning operation:

[0097] In some embodiments, the division operation is implemented by the user's editing operation on the editable dialog box. In the video playback interface, an editable dialog box for dividing the playback area is provided, and the user enters a number in the editable dialog box to implement the division operation of the playback area. When the terminal detects the user's editing operation in the editable dialog box, the number of sub-playback areas is determined based on the number entered by the user. For example, the user enters the number 4 in the editable dialog box, and the terminal determines that the number of sub-playback areas is 4.

[0098] In other embodiments, the division operation is implemented by the user's selection operation of the division option. In the video playback interface, multiple division options for the playback area are provided. The user selects the corresponding division option to implement the division operation of the playback area. When the terminal detects the user's selection operation of the division option, the number of sub-playback areas is determined based on the division option selected by the user. For example, the video playback interface displayed by the terminal provides three division options for the playback area, namely "divided into 2 areas", "divided into 4 areas" and "divided into 6 areas". The user selects the division option of "divided into 4 areas". Based on the user's selection operation of the division option, the terminal determines that the number of sub-playback areas is 4.

[0099] It should be noted that, in actual applications, the implementation of the division operation is not limited to the above two cases. Optionally, the user can implement the corresponding division operation through voice input, quick gestures, etc. The embodiment of the present application does not specifically limit the specific implementation of the division operation.

[0100] 303. The terminal displays multiple sub-playback areas based on the size parameter of the playback area and the number of sub-playback areas.

[0101] In the embodiment of the present application, the size parameter of the play area refers to the width and height of the play area. Based on the size parameter of the play area and the number of sub-play areas determined by the above step 302, the terminal divides the play area and displays multiple sub-play areas. Optionally, a cover image of the target video is displayed in each sub-play area. Optionally, a default image pre-set by the terminal is displayed in each sub-play area. The embodiment of the present application does not specifically limit the display content in the sub-play area in this step.

[0102] Figure 4 is a schematic diagram of a video preview provided by an embodiment of the present application. Figure 4 In the left figure, the size parameters of the playback area in the figure are: width w, height h, where w>0, h>0. The terminal divides the playback area equally based on the size parameters and the number of sub-playback areas. For details, please refer to Figure 4 In the right figure, the number of sub-playback areas is 4, and the sizes of each sub-playback area are the same.

[0103] It should be noted that Figure 4The multiple sub-playback areas shown are obtained by dividing the playback area evenly. In some embodiments, the terminal provides a size adjustment function for the sub-playback area, and can obtain a sub-playback area of ​​corresponding size based on the user's size adjustment requirements for the sub-playback area. For example, the terminal displays a size adjustment interface for the sub-playback area, on which the size parameters of each sub-playback area are displayed. The user can adjust the size parameters of each sub-playback area to trigger a corresponding size adjustment instruction, and the terminal responds to the size adjustment instruction to display the corresponding sub-playback area. For another example, the sub-playback area displayed by the terminal is operable, and the user can perform a zoom operation on the corresponding sub-playback area according to the size adjustment requirements for each sub-playback area, triggering a corresponding size adjustment instruction, and the terminal responds to the size adjustment instruction to display the corresponding sub-playback area. The embodiment of the present application does not specifically limit the size display of the sub-playback area. The above-mentioned method of adjusting the size of the sub-playback area can meet the user's personalized needs for the video preview effect.

[0104] The above steps 302 to 303 are an embodiment of the terminal displaying multiple sub-playing areas in response to the operation of dividing the play area. Optionally, after executing step 301, the terminal can display multiple sub-playing areas in a default manner, for example, the default manner is to display 4 sub-playing areas. The embodiment of the present application does not specifically limit the display manner of multiple sub-playing areas.

[0105] 304. The terminal determines playback information of each sub-playback area based on the multiple sub-playback areas and the playback duration of the target video.

[0106] In the embodiment of the present application, the terminal obtains the play time of the target video, and then determines the play information of each sub-play area based on the play time and the number of sub-play areas, wherein the play information refers to the start play time and play duration of the target video in the sub-play area.

[0107] The following is a specific description of a method for determining the playback information of each sub-playback area. The method includes the following two steps:

[0108] Step 1: The terminal determines the playback duration of the target video in each sub-playback area based on the number of sub-playback areas and the playback duration of the target video.

[0109] Optionally, the terminal evenly divides the play duration of the target video according to the number of sub-play areas to obtain the play duration of the target video in each sub-play area. For example, if the play duration of the target video is 20 minutes and the number of sub-play areas is 4, the play duration of the target video in each sub-play area is 5 minutes.

[0110] Optionally, the terminal provides a function of setting the duration of the playback. The terminal displays a setting interface for the duration of the playback, on which the playback duration of the target video and the time setting options for each sub-playback area are displayed. The user can adjust the time setting options for each sub-playback area to set the playback duration of the target video in each sub-playback area, and then the terminal determines the playback duration of the target video in each sub-playback area based on the user's adjustment operation. For example, the playback duration of the target video is 20 minutes, the number of sub-playback areas is 4, and the terminal displays the time setting options for 4 sub-playback areas. The user adjusts each time setting option to set the playback duration of the target video in the 4 sub-playback areas to 4 minutes, 5 minutes, 6 minutes, and 5 minutes, respectively. The terminal determines the playback duration of the target video in each sub-playback area based on the adjustment operation.

[0111] The embodiment of the present application does not specifically limit the method for determining the playback duration of the target video in each sub-playback area.

[0112] Step 2: The terminal determines the start time of the target video in each sub-playing area based on the play duration of the target video in each sub-playing area and the play duration of the target video.

[0113] In an embodiment of the present application, the terminal uses the playback duration of the target video as the total playback duration, and uses the playback duration of the target video in each sub-playback area as the playback duration of the target video in each sub-playback area, and then determines the starting playback time of the target video in each sub-playback area in sequence according to the order of each sub-playback area.

[0114] Optionally, refer to Figure 4 , an example is given to illustrate this step:

[0115] Figure 4 The right figure shows 4 sub-playing areas, namely, sub-playing area 1, sub-playing area 2, sub-playing area 3 and sub-playing area 4. The playing time of the target video is 20 minutes, and the playing time of the target video in each sub-playing area is 5 minutes. Then, the starting playing time of the target video in sub-playing area 1 is 0 minutes; the starting playing time of the target video in sub-playing area 2 is 5 minutes; the starting playing time of the target video in sub-playing area 3 is 10 minutes; and the starting playing time of the target video in sub-playing area 4 is 15 minutes.

[0116] Optionally, taking the example that the playback duration of the target video in four sub-playback areas is 4 minutes, 5 minutes, 6 minutes and 5 minutes respectively, the starting playback time of the target video in sub-playback area 1 is 0 minutes; the starting playback time of the target video in sub-playback area 2 is 4 minutes; the starting playback time of the target video in sub-playback area 3 is 9 minutes; and the starting playback time of the target video in sub-playback area 4 is 15 minutes.

[0117] Through the above steps 1 and 2, the terminal can determine the playback information of each sub-playing area. For example, the playback information of each sub-playing area is:

[0118] "Sub-playing area 1: the starting playing time is 0 minutes, and the playing duration is 5 minutes;

[0119] Sub-playing area 2: the starting playing time is 5 minutes, and the playing duration is 5 minutes;

[0120] Sub-playing area 3: the starting playing time is 10 minutes and the playing duration is 5 minutes;

[0121] Sub-playing area 4: The starting playing time is 15 minutes and the playing duration is 5 minutes.

[0122] 305. The terminal obtains multiple sub-videos of the target video based on the playback information of each sub-playback area, where one sub-video corresponds to one sub-playback area.

[0123] In an embodiment of the present application, each sub-playback area corresponds to a decoder, and the decoder is used to decode the target video to obtain multiple sub-videos of the target video. Based on the playback information of each sub-playback area, the terminal decodes the target video respectively by the decoders corresponding to each sub-playback area to obtain multiple sub-videos of the target video. Optionally, the terminal obtains the target video, and then sends a decoding instruction to the decoder of each sub-playback area based on the playback information of each sub-playback area. The decoding instruction carries the video data of the target video, the area identifier of the sub-playback area, and the playback information corresponding to the sub-playback area. The decoding instruction is used to instruct the decoder to decode the target video to obtain the sub-video corresponding to the sub-playback area.

[0124] This step specifically includes the following steps 1 and 2:

[0125] Step 1: The decoder corresponding to each sub-playback area locates each key frame corresponding to each start playback time in the target video based on the start playback time of the target video in each sub-playback area.

[0126] Step 2: The decoder corresponding to each sub-playback area decodes the target video based on the playback duration of the target video in each sub-playback area and takes each located key frame as the starting frame to obtain multiple sub-videos corresponding to each playback duration.

[0127] Reference below Figure 4 , taking sub-playback area 2 as an example, this step is specifically explained: the decoder corresponding to the sub-playback area receives a decoding instruction, which carries the video data of the target video, the area identifier "2" of the sub-playback area 2, and the playback information "Sub-playback area 2: the starting playback time is 5 minutes, and the playback duration is 5 minutes". Then, based on the starting playback time, the decoder locates the key frame of the target video after 5 minutes of playback by searching (seeking) in the received video data of the target video, and then decodes the video within 5 minutes after the key frame in the target video based on the playback duration, and obtains the video frame of the sub-video with the key frame as the starting frame and the duration of 5 minutes.

[0128] The above describes the method of obtaining a sub-video corresponding to a sub-playback area by way of example. Correspondingly, the method of obtaining each sub-video can refer to the above method, which will not be repeated here.

[0129] 306. The terminal plays the corresponding sub-video in each sub-playing area.

[0130] In the embodiment of the present application, after the decoder corresponding to each sub-playing area obtains the corresponding sub-video, it decodes the corresponding video frame, and then the terminal plays the corresponding sub-video in each sub-playing area. Figure 4 As shown in the right figure, there are 4 sub-playback areas in total. The terminal plays the corresponding sub-video in each sub-playback area, achieving the goal of playing the entire target video within 5 minutes, increasing the efficiency of video preview to 4 times, and being able to preview the complete content of the target video.

[0131] This step can be achieved in any of the following three ways:

[0132] Method 1: The decoder of each sub-playing area scales the decoded video frame based on the size of each sub-playing area so that the size of the video frame adapts to the size of the corresponding sub-playing area. Then the terminal plays the corresponding sub-video in each sub-playing area.

[0133] Method 2: The decoder of each sub-playback area scales the decoded video frame based on the size of each sub-playback area so that the size of the video frame adapts to the size of the corresponding sub-playback area, and then the decoder of the playback area splices each frame of the video in real time in time sequence to obtain a real-time spliced ​​video frame adapted to the size of the playback area, and then the terminal plays the video in the playback area based on the real-time spliced ​​video frame. This implementation achieves the effect of playing the corresponding sub-video in each sub-playback area by splicing the video frames of each sub-playback area in real time and then playing the spliced ​​video frames in real time in the playback area.

[0134] Method 3: The decoder of each sub-playback area scales the decoded video frame based on the size of each sub-playback area so that the size of the video frame adapts to the size of the corresponding sub-playback area, and then the decoder of the playback area splices the video frames to obtain a video frame that adapts to the size of the playback area, and the terminal plays the video in the playback area based on the video frame. This implementation achieves the effect of playing the corresponding sub-video in each sub-playback area by splicing the video frames of each sub-playback area and then playing the spliced ​​video frames in the playback area.

[0135] It should be noted that, in actual applications, there may be other ways for the terminal to play the corresponding sub-video in each sub-playback area. The three ways described above are only exemplary, and the embodiment of the present application does not specifically limit the way in which the terminal plays the sub-video.

[0136] Through the above steps 301 to 306, the effect of playing multiple segments of a video simultaneously in the entire video playing area is achieved. Optionally, after executing step 306, the terminal can also execute the following step 307.

[0137] 307. In response to the user's playback control operation on any sub-playback area, the terminal plays the sub-video corresponding to the sub-playback area based on the playback control operation.

[0138] In an embodiment of the present application, in the above step 306, when the terminal plays the sub-video in the first two ways, after the terminal plays the corresponding sub-video in each sub-playback area, the user can perform playback control operations on each sub-playback area to achieve playback control of the video playback.

[0139] Optionally, the playback control operation is a full-screen playback operation, and the terminal switches the sub-video played in the sub-playback area to full-screen playback in response to the full-screen playback operation on any sub-playback area. It should be noted that after the terminal switches the sub-video played in the sub-playback area to full-screen playback, in response to the user's exit operation on the current full-screen playback, the terminal exits the full-screen playback and continues to play the corresponding sub-video in the sub-playback area.

[0140] For example, the terminal displays a full-screen play button in a sub-play area. When the terminal detects that a user clicks on a full-screen play button in a sub-play area, the sub-video played in the sub-play area is switched to full-screen play. In the full-screen play mode, the terminal displays an exit full-screen play button. When the terminal detects that a user clicks on the exit full-screen play button, the full-screen play is exited and the corresponding sub-video continues to be played in the sub-play area. The embodiments of the present application do not specifically limit the implementation method of the full-screen play operation.

[0141] Optionally, the playback control operation is a zoom display operation, and the terminal responds to the zoom display operation on any sub-playback area by zooming in and adjusting the size of the sub-playback area, and plays the sub-video corresponding to the sub-playback area in the adjusted sub-playback area.

[0142] For example, the sub-playback area displayed by the terminal is operable, and the user can enlarge and display the sub-playback area according to the enlarged display requirements of any sub-playback area, triggering the corresponding size adjustment instruction, and the terminal responds to the size adjustment instruction to display the enlarged sub-playback area. It should be noted that in the embodiment of the present application, when the terminal enlarges and adjusts the size of the sub-playback area, the size of the remaining sub-playback areas that have not been enlarged and displayed is reduced and adjusted to adapt to the entire playback area; or, the terminal enlarges and adjusts the size of the sub-playback area so that the sub-playback area covers the remaining sub-playback areas that have not been enlarged and displayed. The embodiment of the present application does not specifically limit the implementation method of the terminal adjusting the size of the sub-playback area.

[0143] Optionally, the playback control operation is a positioning playback operation. In response to the positioning playback operation on any sub-playback area, the terminal searches for a key frame corresponding to the positioning playback operation in the sub-video corresponding to the sub-playback area, and plays the corresponding sub-video in the sub-playback area with the key frame as the starting frame.

[0144] For example, the terminal displays a playback progress bar in a sub-playback area. When the terminal detects that the user drags the playback progress bar in a sub-playback area, or clicks a certain position on the playback progress bar, the terminal searches for the corresponding key frame in the sub-video based on the dragging operation or clicking operation, and plays the corresponding sub-video in the sub-playback area with the key frame as the starting frame.

[0145] Optionally, the playback control operation is a pause playback operation, a resume playback operation, a fast forward operation, and a fast rewind operation, etc. In actual applications, the terminal provides multiple playback functions so that users can perform playback control operations based on different playback functions to achieve playback control of video playback. The embodiments of the present application do not make specific limitations on this.

[0146] Optionally, the playback control operation is implemented by a playback control displayed by the terminal in the sub-playing area, and the user can implement playback control of the video playback by operating the playback control. The following is an example of how to implement the playback control operation through the playback control when the terminal plays the sub-video in the first two ways shown in step 306 above.

[0147] In the scenario where the terminal plays the sub-video in the manner shown in step 306 above:

[0148] For example, the playback control is a full-screen play button, which is used to provide a full-screen playback function. When the terminal detects that the user has clicked the full-screen play button in a sub-play area, the decoder corresponding to the sub-play area enlarges the corresponding video frame in the sub-play area to adapt the size of the video frame to the size of the full-screen playback, and then the terminal plays the adjusted video frame in full screen. It should be noted that when the terminal detects that the user has clicked the full-screen play button in a sub-play area, the remaining sub-play areas that have not been clicked continue to play the corresponding sub-videos, or pause the corresponding sub-videos. The user can set the playback status of the remaining sub-play areas as needed, and the embodiments of the present application do not specifically limit this.

[0149] For another example, the playback control is a play button, which is used to provide the playback function of pausing and continuing to play the video. When the terminal detects that the user clicks the play button, the terminal pauses the sub-video in the sub-playback area. When the terminal detects that the user clicks the play button again, the terminal continues to play the sub-video in the sub-playback area.

[0150] In the scenario where the terminal plays the sub-video in the second manner shown in step 306 above:

[0151] For example, the playback control is a full-screen play button, which is used to provide a full-screen playback function. When the terminal detects that the user has clicked the full-screen play button in a sub-play area, the decoder corresponding to the sub-play area will enlarge the corresponding video frame in the sub-play area to adapt the size of the video frame to the size of the full-screen playback, and then the terminal will play the adjusted video frame in full screen. It should be noted that for other sub-play areas that have not been clicked, the terminal pauses splicing the video frames in these sub-play areas, or continues to splice and play the video frames in these sub-play areas in real time in chronological order. The user can set the playback status of the remaining sub-play areas as needed, and the embodiment of the present application does not specifically limit this.

[0152] For another example, the playback control is a play button, which is used to provide the playback function of pausing and continuing to play the video. When the terminal detects a user click operation on the play button, the terminal only continues to splice and play the video frames in the other sub-playback areas that have not been clicked in real time in chronological order. That is, at this time, only the video in the sub-playback area where the click operation is implemented is in a paused playback state, while the other sub-playback areas are in a normal playback state; when the terminal detects the user click operation on the play button again, the terminal uses the video frame currently displayed in the sub-playback area where the click operation is implemented as the starting frame, and splices the video frames to be spliced ​​in other sub-playback areas in real time, and then plays the spliced ​​video frames in real time in the playback area. That is, at this time, the videos in all sub-playback areas are in a normal playback state.

[0153] In an embodiment of the present application, a video preview method is provided. For a video that a user wants to preview quickly, before playing the video, the video is divided into multiple sub-videos according to the playing time, and then the corresponding sub-videos are played in each sub-playing area of ​​the playing area. Through the above method, the playing effect of playing multiple sub-videos of a video at the same time in the entire playing area is achieved, so that the user can quickly preview the complete content of a video, which greatly improves the efficiency of the user's video preview.
