       FIG.  1    is a schematic flowchart of a video playback control method provided by an embodiment of the present disclosure. The method may be executed by a video playback control apparatus, where the apparatus may be implemented by software and/or hardware, and may be configured in an electronic device; typically, it may be configured in a smart phone or a tablet computer. In an implementation, the video playback control method provided by the embodiment of the present disclosure is applicable to a scenario of watching videos through a music list, and in particular, to the scenario of watching short videos shot by other users, where the background music of the short video is the music in the music list. 
     As shown in  FIG.  1   , the video playback control method provided by the embodiment of the present disclosure may include the following. 
     S 101 , receive a first video playback instruction, where the first video playback instruction is triggered to be generated when a user clicks a video playback control within a first target display area in a music list display interface. 
     The first video playback instruction may be used to instruct the electronic device to play a video whose background music is the first target music corresponding to the first target music item, the music list display interface is used to display corresponding music list to the user, the music list may include one or more music items, and one music item in the music list may be considered as music information of certain music that needs to be displayed in the music list. For example, the music item of the certain music may include at least one of: a name of the music, singer information and music length information; each music item in the music list may corresponds to a display area, and each music item may be displayed in its corresponding display area. Accordingly, the first target display area may be considered as the display area clicked by the user in the music list display interface, and the first target music item may be considered as the music item displayed in the first target display area. 
     In this embodiment, the music list displayed in the music list display interface may be a similar (that is, a same type of) music list of certain music or a music list created and collected by the user. For example, the music list is taken as a similar music list of the original music for description below. At this point, the music list display interface displayed by the electronic device may be the similar music list display interface of the original music. 
     For example, please refer to  FIG.  2   , the electronic device may display the music list to the user in the music list display interface, where the music list display interface includes at least one display area  21  (for example, there are three display areas in  FIG.  2   ), and the display areas may have the same height and the display areas are in the original height. Each display area may display a music item having a piece of music within the music list and a video playback control  211  for the user to trigger the electronic device to play a video whose background music is the music corresponding to the music item in the display area; and the display area may also display a collection button  212  for the user to collect/un-collect the music corresponding to the music item in the display area, so that the user may collect or un-collect the music corresponding to the music item displayed in the display area by clicking the collection button  212  in one display area. In addition, each display area may also display a music icon  213  of the music corresponding to the displayed music item, and an audio playback control (not shown in the figure) for the user to play/stop playing the music corresponding to the music item in the display area, so that the user may control the electronic device to play/stop playing the corresponding music by clicking the audio playback control. 
     Specifically, please continue to refer to  FIG.  2   . After the electronic device displays the music list display interface on the screen, when the user wants to watch the video whose background music is a certain music, he clicks the video playback control displayed in the display area (that is, the first target display area) of the music item (that is, the first target music item) having this piece of music. Accordingly, after the electronic device monitors that the user clicks the video playback control displayed in the first target display area, it is determined that the first video playback instruction is received. 
     In a specific implementation, it can be switched into the similar music list display interface of the original music from the music detail interface of the original music. At this point, before receiving the first video playback instruction, it may further include: receiving a similar music display instruction when displaying a music detail interface of the original music, where the similar music display instruction is triggered to be generated when the user clicks a similar music control in the music detail interface; and switching the current display interface from the music detail interface to the similar music list display interface of the original music, where the similar music list display interface includes at least one display area, a height of the display area is an original height value, and a music item of similar music of the original music is displayed in the display area. Where the original music may be music being played by the electronic device or the background music of the video being displayed by the electronic device before the similar music list display interface is displayed. 
     For example, the background music of the video being displayed before the electronic device displays the similar music list display interface is the original music. The electronic device displays the video playback interface based on the trigger operation by the user and plays the video in the video playback interface, as shown in  FIG.  3   , where the background music of the video is the original music, that is, the background music added in the video being played by the electronic device is determined as the original music. When the user wants to view music details of the background music (that is, the original music) added in the video, he clicks the music icon in the video playback interface or the display area of the background music information. Accordingly, when detecting that the user clicks the music icon, the electronic device determines that the music detail display instruction is received and displays the music detail interface, as shown in  FIG.  4   . The music detail interface displays a display music control for the user to view the similar music list of the original music. In addition, the music detail interface may also display an audio playback control for the user to play/stop playing the original music and a collection button for the user to collect/un-collect the original music. Therefore, when the user wants to view the similar music list of the original music, he clicks the display music control in the music detail interface; accordingly, when detecting that the user clicks the similar music control, the electronic device determines that the similar music display instruction is received and displays the similar music list display interface of the original music, as shown in  FIG.  2   . The video displayed in a certain display area may be considered as the video to which the currently displayed video frame in the display area belongs. 
     S 102 , play a first target video in the first target display area and expanding a height of the first target display area to a set height value, where the first target video takes first target music, corresponding to a first target music item displayed in the first target display area, as background music. 
     As for the case that the first target video takes the first target music as the background music, it may be understood as that the background music added in the first target video is the first target music, and the first target video may or may not have audio data other than the added background music; and the set height value may be a preset fixed value or an appropriate height value to which the first target display area may be expanded at present, that is, in case of different locations and/or height expansion modes of the first target display area, the set height value, to which the first target display area is expanded, may be the same or different, and the set height value may be smaller than the height value of the music list display interface. 
     Specifically, after receiving the first video playing instruction, the electronic device acquires the first target video whose background music is the first target music, and plays the first target video in the first target display area; and moves the upper boundary line of the first target display area displayed in the music list display interface upwards and/or moves the lower boundary line of the first target display area displayed in the music list display interface downwards, to expand the height of the first target display area to a set height value. Where the upper boundary line/the lower boundary line of the first target display area displayed in the music list may be considered as that the upper boundary line/the lower boundary line of the first target display area is required to be within the display range of the electronic device screen during height expansion. At this point, accordingly, if the upper boundary line/the lower boundary line of the first target display area is outside the display range of the electronic device screen, the electronic device may first move the location of the first target display area, so as to move the upper boundary line/the lower boundary line outside the display range of the electronic device screen to the location of the upper interface boundary/the lower interface boundary of the music list display interface, and then expand the height of the first target display area to a set height value. 
     In this embodiment, in case of expanding the first target display area to the set height value, only the upper boundary line of the first target display area displayed in the list display interface may be moved, or only the lower boundary line of the first target display area displayed in the list display interface may be moved; or both the upper and lower boundary lines of the first target display area displayed in the list display interface may also be moved simultaneously. 
     In an implementation, the expanding the height of the first target display area to a set height value includes: moving the upper boundary line of the first target display area in the music list display interface upwards until the height of the first target display area reaches the set height value. Where the set height value may be the height value of the first target display area when the upper boundary line of the first target display area is moved upwards to overlap with the interface boundary of the music list display interface, or the set height value may be may be a preset fixed height value. 
     Specifically, the electronic device moves the upper boundary line of the first target display area upwards until the upper boundary line of the first target display area overlaps with the upper interface boundary of the music list display interface. Alternatively, the electronic device moves the upper boundary line of the first target display area upwards until the height of the first target display area reaches a preset fixed height value. Alternatively, the electronic device moves the upper boundary line of the first target display area upwards until the upper boundary line of the first target display area overlaps with the upper interface boundary of the music list display interface or the height of the first target display area reaches the preset fixed height value, for example, the electronic device moves the upper boundary line of the first target display area upwards, and periodically determines, in the moving process, whether the ordinate of the upper boundary line of the first target area is equal to the ordinate of the upper interface boundary on the music list display interface and whether the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value. If the ordinate of the upper boundary line of the first target display area is equal to the ordinate of the upper interface boundary of the music list display interface or the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value, the upper boundary line of the first target display area is stopped from moving upwards; otherwise, the upper boundary line of the first target display area is continuously moved upwards until the ordinate of the upper boundary line of the first target display area is equal to the ordinate of the upper interface boundary of the music list display interface or the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value. 
     In this implementation, when moving the upper boundary of the first target display area upwards, the electronic device may also synchronously move display areas of other music items above the first target display area upwards, so as to prevent other music items above the first target display area from being blocked by the expanded first target display area. At this point, preferably, the expanding the height of the first target display area to the set height value further includes: controlling the other display areas above the first target display area in the music list display interface to move upwards synchronously with the upper boundary line. 
     In another embodiment, the expanding the height of the first target display area to the set height value includes: moving the lower boundary line of the first target display area in the music list display interface downwards until the height of the first target display area reaches the set height value. Where the set height value may be the height value of the first target display area when the lower boundary line of the first target display area is moved downwards to overlap with the interface boundary of the music list display interface, or the set height value may be the preset fixed height value. 
     Specifically, the electronic device moves the lower boundary line of the first target display area downwards until the lower boundary line of the first target display area overlaps with the lower interface boundary of the music list display interface. Alternatively, the electronic device moves the lower boundary line of the first target display area downwards until the height of the first target display area reaches the preset fixed height value. Alternatively, the electronic device moves the lower boundary line of the first target display area downwards until the lower boundary line of the first target display area overlaps with the lower interface boundary of the music list display interface or the height of the first target display area reaches the preset fixed height value, for example, the electronic device moves the lower boundary line of the first target display area downwards, and periodically determines, in the moving process, whether the ordinate of the lower boundary line of the first target area is equal to the ordinate of the lower interface boundary on the music list display interface and whether the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value. If the ordinate of the lower boundary line of the first target display area is equal to the ordinate of the lower interface boundary of the music list display interface or the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value, the lower boundary line of the first target display area is stopped from moving downwards; otherwise, the lower boundary line of the first target display area is continuously moved downwards until the ordinate of the lower boundary line of the first target display area is equal to the ordinate of the lower interface boundary of the music list display interface or the distance between the upper and lower boundary lines of the first target display area reaches the preset fixed height value. 
     In this embodiment, when moving the upper boundary of the first target display area downwards, the electronic device may also synchronously move display areas of other music items below the first target display area downwards, so as to prevent other music items below the first target display area from being blocked by the expanded first target display area. At this point, preferably, the expanding the height of the first target display area to the set height value further includes: controlling the other display areas below the first target display area in the music list display interface to move downwards synchronously with the upper and lower boundary lines. 
     In the third implementation, the expanding the height of the first target display area to the set height value includes: moving the upper boundary line of the first target display area in the music list display interface upwards until the upper boundary line overlaps with the interface boundary of the music list display interface or the height of the first target display area reaches the set height value; and moving the lower boundary line of the first target display area in the music list display interface downwards until the lower boundary line overlaps with the interface boundary of the music list display interface or the height of the first target display area reaches the set height value. Where the set height value may be the preset fixed height value. 
     Specifically, when simultaneously moving the upper and lower boundary lines of the first target display area, the electronic device may periodically determine, in the moving process, that whether the ordinate of the upper boundary line of the first target display area is smaller than the ordinate of the upper interface boundary of the music list display interface, whether the ordinate of the lower boundary line of the first target display area is greater than the ordinate of the lower interface boundary of the music list display interface, and whether the distance between the upper and lower boundary lines of the first target display area reaches the set height value. If the ordinate of the upper boundary line of the first target display area is equal to the ordinate of the upper interface boundary of the music list display interface and the distance between the upper and lower boundary lines of the first target display area does not reach the set height value, the upper boundary line of the first target display area is stopped from moving upwards and the lower boundary line of the first target display area is continuously moved downwards until the distance between the upper and lower boundary lines of the first target display area reaches the set height value. If the ordinate of the lower boundary line of the first target display area is equal to the ordinate of the lower interface boundary of the music list display interface and the distance between the upper and lower boundary lines of the first target display area does not reach the set height value, the lower boundary line of the first target display area is stopped from moving downwards and the upper boundary line of the first target display area is continuously moved until the distance between the upper and lower boundary lines of the first target display area reaches the set height value. Otherwise, the upper lower boundary line and the lower boundary line of the first target display area are continuously moved at the same time until the distance between the upper boundary line and the lower boundary line of the first target display reaches the set height value. Where the moving speed values of the upper boundary line and the lower boundary line of the first target display area may be equal. 
     It can be understood that the electronic device may not simultaneously move the upper boundary line and the lower boundary line of the first target display area. For example, the electronic device preferentially moves the upper boundary line of the first target display area upwards until the upper boundary line of the first target display area overlaps with the upper interface boundary of the music list display interface or the height of the first target display area reaches the set height value, and then moves the lower boundary line of the first target display area downwards until the height of the first target display area reaches the set height value, only when the upper boundary line of the first target display area overlaps with the upper interface boundary of the music list display interface and the height of the first target display area has not yet reached the set height value; alternatively, the electronic device preferentially moves the lower boundary line of the first target display area downwards until the lower boundary line of the first target display area overlaps with the lower interface boundary of the music list display interface or the height of the first target display area reaches the set height value; and then moves the upper boundary line of the first target display area upwards until the height of the first target display area reaches the set height value, only when the lower boundary line of the first target display area overlaps with the lower interface boundary of the music list display interface and the height of the first target display area has not reached the set height value, which is not limited in this embodiment. 
     In this embodiment, when moving the upper boundary line/the lower boundary line of the first target display area, the electronic device may simultaneously move the display areas of other music items above/below the first target display area, so as to prevent other music items from being blocked by the expanded first target display area. At this point, preferably, the expanding the height of the first target display area to the set height value further includes: controlling the other display areas above the first target display area in the music list display interface to move upwards synchronously with the upper boundary line; and controlling the other display areas below the first target display area in the music list display interface to move downwards synchronously with the lower boundary line. After the height of the first target display area is expanded to the set height, the music list display interface is shown in  FIG.  5   , which takes the first target music item as the music item  1  in the music list display interface shown in  FIG.  2    as an example. 
     In addition, when the height of the first target display area is expanded, the first target music item, the music icon, the video playback control and the collection button displayed in the first target display area may move synchronously with the upper boundary line of the first target display area. 
     It can be understood that in the process of expanding the height of the first target display area from the original height value to the set height value, the video frames of the first target video may be displayed completely or incompletely in the first target display area. For example, it is assumed that the current video frame that is required to be displayed currently of the first target display area is shown in  FIG.  6   , when the height to which the first target display area is currently expanded is lower than the height of the current video frame, the electronic device may display, in the first target display area, only part of the picture whose height is equal to the current height of the first target display area among the current video frame, as shown in  FIG.  7   . Alternatively, the height and width of the current video frame is reduced in equal proportion until the height of the current video frame coincides with the current height of the first target display area, and the reduced current video frame is displayed in the first target video, as shown in  FIG.  8   , which is not limited in this embodiment. 
     In the video playback control method provided by this embodiment, the first video playback instruction, which is generated when the user clicks the video playback control in the first target display area of the first target music item in the music list display interface, is received, the first target video whose background music is the first target music corresponding to the first target music item is played in the first target display area, and the height of the first target display area is expanded to the set height. By adopting the above technical solution, this embodiment may realize the function of playing, through the music list, the video whose background music is the music in the music list. When a user wants to watch the video, he may only directly click the video playback control in the corresponding display area in the music list, and there is no need for the user to search for the video based on the music item in the music list, thereby improving the convenience for the user to watch videos and saving time for the user to search videos. 
       FIG.  9    is a schematic flowchart of another video playback control method provided by an embodiment of the present disclosure. The solution of this embodiment may be combined with one or more alternative solutions in the above embodiments. In this embodiment, after playing the first target video in the first target display area, it further includes: receiving a video switching instruction, where the video switching instruction is triggered to be generated when the user swipes left and right on the first target display area; and switching the first target video to other target videos whose background music is the first target music. 
     In an implementation, after playing the first target video in the first target display area, the method further includes: receiving a list return instruction, where the list return instruction is triggered to be generated when the user clicks a non-control display sub-area in the first target display area; and shrinking a height of the first target display area to an original height value, and stopping displaying the first target video in the first target display area. 
     In an implementation, after playing the first target video in the first target display area, the method further includes: receiving a music usage instruction, where the music usage instruction is triggered to be generated when the user clicks a usage control in the first target display area; and switching a current display interface from the music list display interface to a video recording interface, and turning on a camera to record a self-made video whose background music is the first target music. 
     Accordingly, as shown in  FIG.  9   , the video playback control method provided by this embodiment may include the following. 
     S 201 , receive the first video playback instruction, where the first video playback instruction is triggered to be generated when the user clicks the video playback control in the first target display area of the first target music item in the music list display interface. 
     S 202 , play the first target video in the first target display area, expand the height of the first target display area to the set height value, and perform S 203 , S 205  or S 207 , where the first target video takes the first target music corresponding to the first target music item as the background music. 
     S 203 , receive the video switching instruction, where the video switching instruction is triggered to be generated when the user swipes left and right on the first target display area. 
     S 204 , switch the first target video to other target videos whose background music is the first target music, and end the operation. 
     In this embodiment, the video switching instruction may be used to switch the video displayed in the first target display area. 
     Specifically, the electronic device displays the first target video whose background music is the first target music to the user through the first target display area, and the user swipes left and right on the first target display area through a touch pen or a finger when wanting to watch other videos whose background music is the first target music. Accordingly, when monitoring the sliding gesture of the user in the first target display area, the electronic device determines that the video switching instruction is received, the other videos whose background music is the first target music is acquired, and the other videos are displayed in the first target display area; for example, when the loading of other videos is not completed, a certain video frame of the other videos is displayed in the first target display area; and when the loading of other videos is completed, the other videos are played in the first target display area. 
     The video switching instruction may be a video forward switching instruction or a video backward switching instruction. For example, the video backward switching instruction may be generated when the user swipes left on the first target display area, and the video forward switching instruction may be generated when the user swipes right on the first target display area. Accordingly, the electronic device may switch videos in a certain order, for example, the videos whose background music is the first target music may be sorted according to a preset rule, a certain number (for example, 3, 5, 10, etc.) of videos may be selected therefrom as the target videos based on a sorting result, the target video behind the currently displayed target video in the sorting result is displayed every time the video backward switching instruction is received, and the target video before the currently displayed target video in the sorting result is displayed every time the video forward switching instruction is received. 
     S 205 , receive a music usage instruction, where the music usage instruction is triggered to be generated when the user clicks a usage control in the first target display area. 
     S 206 , switch the current display interface from the music list display interface to the video recording interface, and turn on a camera to record a self-made video whose background music is the first target music, and end the operation. 
     The music usage instruction may be used for the user to trigger the operation of recording videos whose background music is the first target music. The usage control may pop out from one side (such as the right side) of the first target display area when the electronic device receives the first video playback instruction, and move synchronously with the upper boundary line of the first target display area during or after the pop-out; accordingly, the usage control may be retracted to one side of the target display area according to its pop-out route when the electronic device receives a second video playback instruction or the list return instruction, and move synchronously with the upper boundary line of the first target display area in the retraction process. In addition, when the usage control pops out or retracts from a display side of the collection button (such as the right side of the first target display area), the collection button displayed in the first display area may also move synchronously with the usage control to avoid being blocked by the usage control. 
     Specifically, the electronic device displays the first target video whose background music is the first target music to the user through the first target display area, and the user clicks the usage control in the first target display area when he wants to record the video with the background music as the first target music; accordingly, when detecting that the user clicks the usage control in the first target display area, the electronic device determines that the music usage instruction is received, and displays the video recording interface and turns on the camera (such as a front camera or a rear camera), so that the user may control the camera in the video recording interface to record the video; and after the video recording is completed, a self-made video whose background music is the first target music may be obtained. 
     S 207 , receive a list return instruction, where the list return instruction is triggered to be generated when the user clicks the non-control display sub-area in the first target display area. 
     S 208 , shrink the height of the first target display area to the original height value, and stop displaying the first target video in the first target display area. 
     The list return instruction may be used to return the status that none of the display areas of the music list display interface is performed by a height expansion or displays videos. The non-control display sub-area may be understood as the sub-area in which no control is displayed in the first target display area. Stopping displaying the first target video in the first target display area may be understood as stopping displaying any video frame of the first target video in the first target display area, that is, the video frame is no longer displayed in the first target display area. 
     Specifically, as shown in  FIG.  5   , the electronic device displays the target video whose background music is the first target music to the user through the first target display area, and the user clicks the non-control display sub-area in the first target display area when the user does not want to watch the video corresponding to the music which is corresponding to any music item in the music list; accordingly, when detecting that the user clicks on the non-control display sub-area of the first target display area, the electronic device determines that the list return instruction is received, shrinks the height of the first target display area to the original height value, and stops displaying videos in the first target display area. After the shrinking process, the music list display interface of the first target display area can be shown in  FIG.  2   . 
     In this embodiment, the shrinking method adopted for shrinking the height of the first target display area to the original height value may be selected as required, for example, only the lower boundary line of the first target display area may be moved upwards, only the upper boundary line of the first target display area may be moved downwards, or the lower boundary line of the first target display area may be moved upwards and the upper boundary line of the first target display area may be moved downwards, at the same time. In this embodiment, it is preferably to control the boundary line (i.e., the boundary line of the first target display area that is moved when the height of the first target display area is expanded) to move a distance which is the same as it moves during expanding, with the same speed value as the speed value and in an opposite direction from the direction during the expanding, so that the music item displayed in the music list display interface after shrinking and the music item displayed in the music list before expansion are at the same display location. 
     It can be understood that when the upper boundary line of the first target display area moves, other display areas above the first target display area and the first target music item, the music icon, the video playback control and the collection button displayed in the first target area may move synchronously with the upper boundary line; and when the lower boundary line of the first target display area moves, other display areas below the first target display area may move synchronously with the lower boundary line. 
     In an implementation, the above video playback control method may further include: receiving a second video playback instruction, where the second video playback instruction is triggered to be generated when the user clicks a video playback control in a second target display area in the music list display interface; shrinking a height of the first target display area to an original height value, and stopping displaying the first target video in the first target display area; and playing a second target video in the second target display area and expanding a height of the second target display area to a set height value, where the second target video takes second target music corresponding to a second target music item displayed within the second target area as the background music. 
     The second video playback instruction may be used to instruct the electronic device to play, in the second target display area, the video whose background music is the second target music corresponding to the second target music item. 
     Specifically, as shown in  FIG.  5   , when the electronic device plays the first target video in the first target display area, the user may view music items in the music list (such as a music item  3  in  FIG.  5   ) whose display area is completely or partially outside the screen display area of the electronic device by swiping up and down, and the user may click the video playback control in the second target display area that displays the music item when he wants to watch the video whose background music is the music (i.e., the second target music) corresponding to other music items (i.e., the second target music item). Accordingly, when monitoring that the user clicks the video playback control in the second target display area, the electronic device determines that the second video playback instruction is received, stops displaying the first target video in the first target display area, shrinks the height of the first target display area to the original height value, plays the second target video whose background music is the second target music in the second target display area and expands the height of the second target display area to the set height value. The height of the first target display area is shrank to the original height value, and after the height of the second target display area is expanded to the set height value, the music list display interface is shown in  FIG.  10   . In  FIG.  10   , for example, the second target music item is taken as the music item  3  in  FIG.  5   . 
     Therefore, based on the received different instructions, the electronic device may realize: the switching of the videos displayed in the music list display interface, the recording of the video whose background music is the background music of the currently displayed video, and the return of the original status of the music list, thereby providing more reference videos for the user to record a video and reducing the difficulty of recording a video by the user.
