It should be noted that, the embodiment of the present application is not limited to whether the target video is a complete video or a segment video in a complete video.
302. The terminal determines the number of the sub-play areas in response to the division operation of the play area.
In the embodiment of the application, after the terminal divides the playing area, the obtained divided playing area includes a plurality of partitions, each partition is a sub-playing area, and the size of the sub-playing area is smaller than that of the playing area. The terminal detects the dividing operation of the user to the playing area, and determines the number of the sub-playing areas based on the dividing operation.
Two implementations of the partitioning operation are explained below:
in some embodiments, the partitioning operation is implemented by a user editing operation on an editable dialog box. In the video playing interface, an editable dialog box for dividing the playing area is provided, a user inputs numbers in the editable dialog box to realize the dividing operation of the playing area, and when the terminal detects the editing operation of the user in the editable dialog box, the number of the sub-playing areas is determined based on the numbers input by the user. For example, if the user inputs the number 4 in the editable dialog box, the terminal determines that the number of the sub-play areas is 4.
In other embodiments, the partitioning is performed by a user selection of a partitioning option. In a video playing interface, a plurality of division options for the playing area are provided, a user realizes the division operation of the playing area by selecting the corresponding division options, and when the terminal detects the selection operation of the user on the division options, the number of the sub-playing areas is determined based on the division options selected by the user. For example, three division options for the playing area are provided in a video playing interface displayed by the terminal, namely "division into 2 areas", "division into 4 areas", and "division into 6 areas", the user selects the division option "division into 4 areas", and the terminal determines that the number of the sub-playing areas is 4 based on the selection operation of the user on the division option.
It should be noted that, in practical applications, the implementation manner of the dividing operation is not limited to the above two cases. Optionally, the user can implement the corresponding division operation by means of voice input, shortcut gestures, and the like. The embodiment of the present application does not specifically limit the specific implementation manner of the dividing operation.
303. The terminal displays a plurality of sub-play areas based on the size parameter of the play area and the number of the sub-play areas.
In the embodiment of the present application, the size parameter of the playing area refers to the width and height of the playing area. The terminal divides the playing area based on the size parameter of the playing area and the number of the sub-playing areas determined in the above step 302, and displays a plurality of sub-playing areas. Optionally, a cover picture of the target video is displayed in each sub-play area. Optionally, a default picture preset by the terminal is displayed in each sub-play area. The display content in the sub-play area in this step is not specifically limited in the embodiment of the present application.
Fig. 4 is a schematic diagram of a video preview provided in an embodiment of the present application. Referring to the left diagram in fig. 4, the size parameters of the playing area in the diagram are: width w and height h, wherein w >0 and h > 0. The terminal equally divides the playing area based on the size parameter and the number of the sub-playing areas, which may specifically refer to the right diagram in fig. 4, where the number of the sub-playing areas is 4, and the sizes of the sub-playing areas are the same.
The plurality of sub-play areas shown in fig. 4 are obtained by equally dividing the play area. In some embodiments, the terminal provides a size adjustment function for the sub-play area, and can obtain the sub-play area with a corresponding size based on the size adjustment requirement of the user for the sub-play area. For example, the terminal displays a size adjustment interface of the sub-play areas, on the size adjustment interface, the size parameter of each sub-play area is displayed, a user can trigger a corresponding size adjustment instruction by adjusting the size parameter of each sub-play area, and the terminal responds to the size adjustment instruction to display the corresponding sub-play area. For another example, the sub-play areas displayed by the terminal are operable, the user can perform zoom operation on the corresponding sub-play areas according to the size adjustment requirement on each sub-play area, trigger the corresponding size adjustment instruction, and the terminal responds to the size adjustment instruction to display the corresponding sub-play areas. The size display of the sub-play area is not specifically limited in the embodiment of the present application. By the method for adjusting the size of the sub-playing area, the personalized requirements of the user on the video preview effect can be met.
The above steps 302 to 303 are an embodiment in which the terminal displays a plurality of sub-play areas in response to the division operation of the play area. Optionally, after performing step 301, the terminal can display a plurality of sub-play areas in a default manner, for example, the default manner is to display 4 sub-play areas. The display mode of the multiple sub-play areas is not specifically limited in the embodiment of the present application.
304. And the terminal determines the playing information of each sub-playing area based on the plurality of sub-playing areas and the playing time of the target video.
In the embodiment of the application, the terminal acquires the playing time of the target video, and then determines the playing information of each sub-playing area based on the playing time and the number of the sub-playing areas. The playing information refers to the starting playing time and the playing duration of the target video in the sub-playing area.
The following describes a method for determining the playing information of each sub-playing area, and the method includes the following two steps:
the method comprises the following steps: and the terminal determines the playing duration of the target video in each sub-playing area based on the number of the sub-playing areas and the playing duration of the target video.
Optionally, the terminal averagely divides the playing time of the target video according to the number of the sub-playing areas to obtain the playing duration of the target video in each sub-playing area. For example, if the playing time of the target video is 20 minutes, and the number of the sub-playing areas is 4, the playing duration of the target video in each sub-playing area is 5 minutes.
Optionally, the terminal provides a function of setting the play duration. The terminal displays a setting interface of the playing duration, the playing duration of the target video and the time setting option of each sub-playing area are displayed on the setting interface, a user can adjust the time setting option of each sub-playing area to set the playing duration of the target video in each sub-playing area, and then the terminal determines the playing duration of the target video in each sub-playing area based on the adjustment operation of the user. For example, the playing time of the target video is 20 minutes, the number of the sub-playing regions is 4, the terminal displays time setting options of the 4 sub-playing regions, the user sets the playing durations of the target video in the 4 sub-playing regions to be 4 minutes, 5 minutes, 6 minutes and 5 minutes respectively by performing adjustment operation on each time setting option, and the terminal determines the playing durations of the target video in each sub-playing region based on the adjustment operation.
The method for determining the playing duration of the target video in each sub-playing area is not particularly limited in the embodiment of the present application.
Step two: and the terminal determines the initial playing time of the target video in each sub-playing area based on the playing duration of the target video in each sub-playing area and the playing duration of the target video.
In the embodiment of the application, the terminal takes the playing time length of the target video as the total playing time length, takes the playing duration time of the target video in each sub-playing area as the playing time length of the target video in each sub-playing area, and then sequentially determines the initial playing time of the target video in each sub-playing area according to the sequence of each sub-playing area.
Alternatively, this step is illustrated below with reference to fig. 4:
the right diagram of fig. 4 shows 4 sub-play areas, which are sub-play area 1, sub-play area 2, sub-play area 3, and sub-play area 4. The playing time of the target video is 20 minutes, the playing duration of the target video in each sub-playing area is 5 minutes, and the initial playing time of the target video in the sub-playing area 1 is 0 minute; the initial playing time of the target video in the sub-playing area 2 is 5 minutes; the initial playing time of the target video in the sub-playing area 3 is 10 minutes; the initial playing time of the target video in the sub-playing area 4 is 15 minutes.
Optionally, taking the playing durations of the target video in the 4 sub-playing regions as 4 minutes, 5 minutes, 6 minutes and 5 minutes, respectively, as an example, the starting playing time of the target video in the sub-playing region 1 is 0 minute; the initial playing time of the target video in the sub-playing area 2 is 4 minutes; the initial playing time of the target video in the sub-playing area 3 is 9 minutes; the initial playing time of the target video in the sub-playing area 4 is 15 minutes.
Through the first step and the second step, the terminal can determine the playing information of each sub-playing area, for example, the playing information of each sub-playing area is as follows:
"sub-play area 1: the initial playing time is 0 minute, and the playing duration time is 5 minutes;
sub-play area 2: the initial playing time is 5 minutes, and the playing duration time is 5 minutes;
sub-play area 3: the initial playing time is 10 minutes, and the playing duration time is 5 minutes;
sub-play area 4: the initial play time is 15 minutes and the play duration is 5 minutes ".
305. The terminal acquires a plurality of sub-videos of the target video based on the playing information of each sub-playing area, wherein one sub-video corresponds to one sub-playing area.
In the embodiment of the present application, each sub-play area corresponds to a decoder, and the decoder is configured to decode a target video to obtain a plurality of sub-videos of the target video. And the terminal decodes the target video by the decoder corresponding to each sub-playing area based on the playing information of each sub-playing area to obtain a plurality of sub-videos of the target video. Optionally, the terminal acquires the target video, and then sends a decoding instruction to the decoder of each sub-play area based on the play information of each sub-play area, where the decoding instruction carries video data of the target video, an area identifier of the sub-play area, and play information corresponding to the sub-play area, and the decoding instruction is used to instruct the decoder to decode the target video, so as to obtain a sub-video corresponding to the sub-play area.
The method specifically comprises the following steps of:
the method comprises the following steps: and the decoder corresponding to each sub-playing area locates each key frame corresponding to each starting playing time in the target video based on the starting playing time of the target video in each sub-playing area.
Step two: and the decoder corresponding to each sub-playing area decodes the target video by taking each positioned key frame as an initial frame based on the playing duration of the target video in each sub-playing area to obtain a plurality of sub-videos corresponding to each playing duration.
The following will specifically describe this step by taking the sub-play area 2 as an example with reference to fig. 4: the decoder corresponding to the sub-play area receives a decoding instruction, and the decoding instruction carries the video data of the target video, the area identifier "2" of the sub-play area 2, and the play information "sub-play area 2: the initial playing time is 5 minutes, the playing duration is 5 minutes ", then the decoder locates a key frame of the target video after playing for 5 minutes in a searching (seek) mode in the received video data of the target video based on the initial playing time, and then decodes the video within 5 minutes from the key frame in the target video based on the playing duration to obtain a video frame of a sub-video with the key frame as the initial frame and the duration of 5 minutes.
The method for acquiring a sub-video corresponding to a certain sub-play area is described above by way of example, and accordingly, the method for acquiring each sub-video may refer to the above method, which is not described herein again.
306. And the terminal plays the corresponding sub-video in each sub-playing area.
In the embodiment of the application, after the decoder corresponding to each sub-play area acquires the corresponding sub-video, the corresponding video frame is decoded, and then the terminal plays the corresponding sub-video in each sub-play area. Referring to the right diagram in fig. 4, there are 4 sub-play areas in total, and the terminal plays the corresponding sub-video in each sub-play area, so that the playing of the complete segment of the target video within 5 minutes is realized, the efficiency of video preview is improved to 4 times, and the complete content of the target video can be previewed.
This step can be achieved in any of three ways:
the first method is as follows: and the decoder of each sub-playing area scales the decoded video frame based on the size of each sub-playing area so as to adapt the size of the video frame to the size of the corresponding sub-playing area. And then the terminal respectively plays the corresponding sub-videos in each sub-playing area.
The second method comprises the following steps: the decoder of each sub-playing area scales the video frame obtained by decoding based on the size of each sub-playing area so as to enable the size of the video frame to be adapted to the size of the corresponding sub-playing area, then the decoder of the playing area performs real-time splicing on each frame of video in each video frame according to the time sequence to obtain the real-time spliced video frame adapted to the size of the playing area, and then the terminal plays the video in the playing area based on the real-time spliced video frame. In the embodiment, the video frames of the sub-playing areas are spliced in real time, and then the spliced video frames are played in the playing areas in real time, so that the playing effect of playing the corresponding sub-videos in the sub-playing areas is achieved.
The third method comprises the following steps: and the decoder of each sub-playing area scales the decoded video frame based on the size of each sub-playing area so as to enable the size of the video frame to be adapted to the size of the corresponding sub-playing area, then the decoder of the playing area splices the video frames to obtain a video frame adapted to the size of the playing area, and the terminal plays the video based on the video frame in the playing area. In the embodiment, the video frames of the sub-playing areas are spliced, and then the spliced video frames are played in the playing area, so that the playing effect of playing the corresponding sub-videos in the sub-playing areas is achieved.
It should be noted that, in practical applications, there may be other manners for the terminal to play the corresponding sub-video in each sub-play area, and the three manners described above are merely illustrative, and the manner for the terminal to play the sub-video is not specifically limited in the embodiment of the present application.
Through the above steps 301 to 306, a playing effect of simultaneously playing a plurality of segments of a segment of video in the whole video playing area is achieved, and optionally, after executing step 306, the terminal can also execute the following step 307.
307. And the terminal responds to the playing control operation of the user on any sub-playing area and plays the sub-video corresponding to the sub-playing area based on the playing control operation.
In this embodiment of the application, in step 306, when the implementation manner of playing the sub-video by the terminal is the first two manners, after the terminal plays the corresponding sub-video in each sub-play area, the user can perform play control operation on each sub-play area, so as to implement play control on video playing.
Optionally, the playing control operation is a full-screen playing operation, and the terminal switches the sub-video played in the sub-playing area to the full-screen playing in response to the full-screen playing operation on any sub-playing area. It should be noted that, after the terminal switches the sub-video played in the sub-play area to full-screen play, the terminal responds to the exit operation of the user on the current full-screen play, exits from full-screen play, and continues to play the corresponding sub-video in the sub-play area.
For example, the terminal displays a full-screen play button in a sub-play area, when the terminal detects that a user clicks the full-screen play button in a certain sub-play area, the sub-video played in the sub-play area is switched to full-screen play, the terminal displays a full-screen exit button in a full-screen play mode, when the terminal detects that the user clicks the full-screen exit button, the terminal exits full-screen play, and the corresponding sub-video continues to be played in the sub-play area. The embodiment of the present application does not specifically limit the implementation manner of the full screen play operation.
Optionally, the playing control operation is an enlargement display operation, the terminal responds to the enlargement display operation of any sub-playing area, enlarges and adjusts the size of the sub-playing area, and plays the sub-video corresponding to the sub-playing area in the adjusted sub-playing area.
For example, the sub-play area displayed by the terminal is operable, a user can perform an amplification display operation on the sub-play area according to an amplification display requirement on any sub-play area, trigger a corresponding size adjustment instruction, and the terminal responds to the size adjustment instruction to display the amplified sub-play area. It should be noted that, in the embodiment of the present application, when the terminal performs the enlargement adjustment on the size of the sub-play area, correspondingly, the size of the remaining sub-play areas that are not subjected to the enlargement display operation is reduced and adjusted to adapt to the entire play area; or, the terminal performs amplification adjustment on the size of the sub-playing area, so that the sub-playing area covers the rest sub-playing areas which are not subjected to amplification display operation. The embodiment of the present application does not specifically limit the implementation manner of adjusting the size of the sub-play area by the terminal.
Optionally, the playing control operation is a positioning playing operation, and the terminal, in response to the positioning playing operation for any one of the sub-playing areas, searches for a key frame corresponding to the positioning playing operation in the sub-video corresponding to the sub-playing area, and plays the corresponding sub-video in the sub-playing area with the key frame as an initial frame.
For example, the terminal displays a playing progress bar in a sub-playing area, and when the terminal detects a dragging operation performed by a user on the playing progress bar in a certain sub-playing area, or a clicking operation on a certain position on the playing progress bar, the terminal searches for a corresponding key frame in the sub-video based on the dragging operation or the clicking operation, and plays the corresponding sub-video in the sub-playing area with the key frame as a start frame.
Optionally, the play control operation is a pause play operation, a resume play operation, a fast forward operation, a fast backward operation, and the like, and in practical applications, the terminal provides multiple play functions, so that a user performs the play control operation based on different play functions to realize play control of video play, which is not specifically limited in this embodiment of the present application.
Optionally, the playing control operation is implemented by a playing control displayed in the sub-playing area by the terminal, and the user can implement playing control of video playing by operating the playing control. Next, how to implement the play control operation by the play control when the terminal plays the sub-video in the first two manners shown in step 306 is illustrated.
In a scenario where the terminal plays the sub-video in the first manner shown in step 306:
for example, the playing control is a full-screen playing button for providing a full-screen playing function, when the terminal detects a click operation performed by a user on the full-screen playing button in a certain sub-playing area, a decoder corresponding to the sub-playing area amplifies a video frame corresponding to the sub-playing area, so that the size of the video frame is adapted to the size of full-screen playing, and then the terminal performs full-screen playing on the adjusted video frame. It should be noted that, when the terminal detects that the user performs a click operation on a full-screen play button in a certain sub-play area, the other sub-play areas that are not subjected to the click operation continue to play the corresponding sub-video, or the playing of the corresponding sub-video is suspended, and the user can set the play states of the other sub-play areas according to the requirement, which is not specifically limited in this embodiment of the application.
For another example, the playing control is a playing button, and is configured to provide a playing function of pausing and continuing to play the video, when the terminal detects a click operation performed by the user on the playing button, the terminal pauses to play the sub-video in the sub-playing area, and when the terminal detects a click operation performed by the user on the playing button again, the terminal continues to play the sub-video in the sub-playing area.
In a scenario where the terminal plays the sub-video in the manner shown in step 306:
for example, the playing control is a full-screen playing button for providing a full-screen playing function, when the terminal detects that a user clicks the full-screen playing button in a certain sub-playing area, a decoder corresponding to the sub-playing area amplifies a video frame corresponding to the sub-playing area, so that the size of the video frame is adapted to the size of full-screen playing, and then the terminal performs full-screen playing on the adjusted video frame. It should be noted that, for other sub-play areas where the click operation is not performed, the terminal suspends splicing the video frames in the sub-play areas, or continues to splice and play the video frames in the sub-play areas in real time according to the time sequence, and the user can set the play states of the other sub-play areas according to the requirement, which is not specifically limited in this embodiment of the present application.
For another example, the playing control is a playing button for providing a playing function of pausing and continuing to play the video, when the terminal detects the click operation performed by the user on the playing button, the terminal continues to splice and play the video frames in the sub-playing areas in real time according to the time sequence only for other sub-playing areas not subjected to the click operation, that is, only the video in the sub-playing area subjected to the click operation is in the paused playing state, and the other sub-playing areas are in the normal playing state; when the terminal detects the click operation performed by the user on the play button again, the terminal uses the currently displayed video frame in the sub-play area where the click operation is performed as the starting frame to be spliced with the video frames to be spliced currently in other sub-play areas in real time, and then plays the spliced video frames in the play area in real time, that is, the videos in all the sub-play areas are in a normal play state at this time.
In the embodiment of the application, a video preview method is provided, in which for a segment of video that a user wants to quickly preview, before playing the video, the video is divided into a plurality of sub-videos according to the playing time length, and then corresponding sub-videos are respectively played in each sub-playing area of a playing area. By the method, the playing effect of simultaneously playing the plurality of sub-videos of the video segment in the whole playing area is realized, so that a user can quickly preview the complete content of the video segment, and the efficiency of previewing the video by the user is greatly improved.
