     DETAILED DESCRIPTION 
     Examples will be described here in detail and shown in the accompanying drawings. Unless otherwise stated, when the following description refers to the accompanying drawings, the same number in the different accompanying drawings indicates the same element or similar elements. Implementations described in the following examples do not represent all implementations consistent with the disclosure. On the contrary, they are merely examples of an apparatus and method consistent with some aspects of the disclosure as detailed in appended claims. 
     The disclosure relates to the technical field of multimedia, in particular to a method and apparatus for processing multimedia data, and a storage medium. 
     In the related art, with rapid development of an Internet technology, there are more and more types of smart devices that a user can select, and interaction between smart terminals is more and more common. Normally, data transmission between the smart devices (such as a smartphone and a tablet computer) needs to pass through a multi-verification and complicated connection process, and data generated in a smart terminal cannot be instantaneously transmitted to another smart terminal, so data transmission efficiency and time-efficient performance are low. 
     Before introducing a method and apparatus for processing multimedia data and a storage medium provided by the disclosure, first of all, application scenarios involved in various examples of the disclosure are introduced. The application scenarios may include at least one sending end and at least one receiving end, information interaction may be performed between the sending end and the receiving end, and the sending end and the receiving end can be switched to each other. Both the sending end and the receiving end may be any type of smart device capable of sending, receiving and processing multimedia information, for example, a smartphone, a tablet computer, a smart television, a personal digital assistant (PDA), a projector, a portable computer and other mobile terminals, or may also be a fixed terminal such as a desktop computer. 
       FIG.  1    is a flowchart of a method for processing multimedia data shown according to an example. As shown in  FIG.  1   , the method is performed by a sending end and includes the following steps. 
     In step S 101 , target multimedia data are obtained and displayed in response to a processing instruction. 
     For example, a user, when using the sending end, often browses photos, takes a picture, takes a screenshot, records a video and other operations, in the meantime, the user may also share multimedia data such as a picture, a video, a dynamic image generated by these operations to other terminals, namely, a receiving end. The user may perform a first specified operation on the sending end so as to trigger the processing instruction. The first specified operation may be an operation of taking a picture, an operation of taking a screenshot, a recording operation and the like, or may also be a selection operation implemented by gestures of clicking, swiping and the like in a preset multimedia library. The multimedia library may be a picture library, a video library and the like stored locally in the sending end, or may also be a picture library, a video library and the like obtained by the sending end through a network. The sending end, after receiving the processing instruction, can obtain the target multimedia data corresponding to the processing instruction and display the target multimedia data on a display interface of the sending end. The target multimedia data may be a photo shot by the operation of taking a picture, or may also be a picture generated by the operation of taking a screenshot, or may also be a video or a dynamic image recorded by the recording operation, or may also be a picture, a video or a dynamic image selected in the multimedia library by the selection operation, which is not specifically limited by the disclosure. 
     In step S 102 , the target multimedia data are sent to the receiving end through a preset communication connection so as to make the receiving end display the target multimedia data synchronously in a specified region of a display interface of the receiving end. 
     For example, the sending end, while displaying the target multimedia data on the display interface of the sending end, may send the obtained target multimedia data to the receiving end through the preset communication connection. Specifically, the sending end may directly send the target multimedia data to the receiving end when obtaining the target multimedia data, or may also further obtain a transmission instruction when obtaining the target multimedia data and send the target multimedia data to the receiving end according to the transmission instruction. The receiving end, after receiving the target multimedia data, may display the target multimedia data synchronously in the specified region of the display interface of the receiving end. The specified region may be, for example, an upper left angle, an upper right angle, a lower left angle, a lower right angle, a center region and the like of the display interface. Furthermore, the receiving end may also display the target multimedia data in the specified region according to a preset displaying mode. For example, the target multimedia data may be displayed in the specified region according to an air bubble displaying mode, or may also be displayed in the specified region according to a preset photo frame displaying mode, or may also be displayed in the specified region according to a preset filter or special effect displaying mode. In this way, through the preset communication connection between the sending end and the receiving end, transmission of the multimedia data can be performed fast and conveniently, and a data interaction efficiency is improved. 
     To sum up, in the disclosure, the sending end firstly obtains and displays the target multimedia data in response to the processing instruction and then sends the target multimedia data to the receiving end through the preset communication connection. The receiving end, after receiving the target multimedia data, displays the target multimedia data synchronously in the specified region of the display interface of the receiving end. In the disclosure, the multimedia data are sent to the receiving end through the preset communication connection such that the receiving end can display the target multimedia data synchronously, so the efficiency, the time-efficient performance and the convenience of transmission of the multimedia data are improved. 
       FIG.  2    is a flowchart of another method for processing multimedia data shown according to an example. As shown in  FIG.  2   , there are a plurality of receiving ends, and before step S 102 , the method includes step S 101  and further includes the following steps. 
     In step S 103 , a transmission instruction is obtained, and indication information included in the transmission instruction is identified. 
     In step S 104 , a target receiving end corresponding to the indication information is determined among the plurality of receiving ends. 
     Correspondingly, an implementation of step S 102  may be: the target multimedia data are sent to the target receiving end through the communication connection. 
     For example, there may be a plurality of receiving ends corresponding to the sending end, in other words, the sending end may establish the communication connection with the plurality of receiving ends at the same time. The sending end, after obtaining the target multimedia data, may further obtain the transmission instruction and parse the transmission instruction so as to obtain the indication information included in the transmission instruction. The transmission instruction may be triggered by the user when the first specified operation is performed, that is, the transmission instruction and the processing instruction may be triggered at the same time, or may be triggered when a second specified operation is performed after the user obtains the target multimedia data on the sending end. The second specified operation may be, for example, clicking, swiping or stretching the target multimedia data, and the indication information may be used to, for example, indicate a direction, or may also be used to indicate a terminal identifier, or may also be used to indicate a terminal type. 
     Furthermore, the sending end may determine the target receiving end corresponding to the indication information among the plurality of receiving ends according to the indication information and send the target multimedia data to the target receiving end through the communication connection. If the indication information can indicate the direction, a location where the target receiving end is located matches a direction indicated by the indication information. If the indication information can indicate the terminal identifier, a terminal identifier of the target receiving end matches the terminal identifier indicated by the indication information. If the indication information can indicate the terminal type, a type of the target receiving end matches the terminal type indicated by the indication information. Specifically, in response to determining that the second specified operation is swiping, the indication information may indicate a swiping direction, and the target receiving end is a receiving end matching the swiping direction. For example, when the user swipes the target multimedia data leftwards, the target receiving end may be a receiving end on left of the sending end. In response to determining that the second specified operation is to input a terminal identifier, the indication information may indicate the terminal identifier, and the target receiving end is a receiving end matching the terminal identifier. For example, when the user inputs a terminal identifier “123456”, the target receiving end is a receiving end with the terminal identifier “123456”. In response to determining that the second specified operation is to select the terminal type, the indication information may indicate the terminal type, and the target receiving end is a receiving end matching the terminal type. For example, in response to determining that the terminal type selected by the user is a tablet computer, the target receiving end is a receiving end with the terminal type of a tablet computer. In this way, through the communication connection between the sending end and the plurality of receiving ends, interaction of the multimedia data among the plurality of devices can be implemented faster and more conveniently, and the data interaction efficiency is improved. 
       FIG.  3    is a flowchart of another method for processing multimedia data shown according to an example. As shown in  FIG.  3   , the indication information includes: gesture direction information. Step S 104  may be implemented through the following steps. 
     In step S 1041 , a location relation between each of the receiving ends and the sending end is determined. 
     In step S 1042 , a receiving end which the location relation with the sending end matching the gesture direction information is used as the target receiving end. 
     For example, the indication information may be the gesture direction information, the gesture direction information may be the swiping direction on a screen by the user, or may also be a direction of a gesture executed on the screen by the user, which is not specifically limited by the disclosure. The sending end may firstly detect the location relation between each of the receiving ends and the sending end through a specified detection apparatus. The specified detection apparatus may be a radar, ultrasonic waves, an infrared detection apparatus, a signal intensity sensor and any other type of apparatus capable of identifying a direction of the receiving end. After that, the location relation with the sending end may be determined, and the receiving end matching the gesture direction information is used as the target receiving end. For example, there are three receiving ends, which are located in front, on left and on right of the sending end respectively, in response to determining that a direction indicated by the gesture direction information is left, it can be determined that the target receiving end is a receiving end located on left of the sending end, so that the target multimedia data are sent to the receiving end on left of the sending end. 
       FIG.  4    is a flowchart of another method for processing multimedia data shown according to an example. As shown in  FIG.  4   , before step S 102 , the method includes step S 101  and further includes the following steps. 
     In step S 105 , the transmission instruction is obtained, and the location information included in the transmission instruction is identified. 
     In step S 106 , the target multimedia data are divided into first multimedia sub-data and second multimedia sub-data according to the location information, and the first multimedia sub-data are displayed on the display interface of the sending end. 
     Correspondingly, an implementation of step S 102  may be: the target multimedia data and the identifier of the second multimedia sub-data are sent to the receiving end so as to make the receiving end display the second multimedia sub-data in the specified region of the display interface of the receiving end, in which the identifier is configured to indicate a location of the second multimedia sub-data in the target multimedia data. 
     For example, the sending end, after obtaining the target multimedia data, may further obtain the transmission instruction and parse the transmission instruction so as to obtain the location information included in the transmission instruction. The transmission instruction may be, for example, triggered when the user performs the operations such as clicking or swiping the multimedia data, and the location information may be configured to indicate a location of the target multimedia data on a display interface. After that, the target multimedia data may be divided into the first multimedia sub-data and the second multimedia sub-data according to the location information, and the first multimedia sub-data are displayed on the display interface of the sending end. In response to determining that the target multimedia data are a picture, the first multimedia sub-data and the second multimedia sub-data may be regarded as two sub-pictures divided from the picture. In response to determining that the target multimedia data are a video, the first multimedia sub-data and the second multimedia sub-data may be regarded as two sub-videos divided from the video, and a video frame included in each sub-video is a part of a video frame included in the video. Furthermore, the target multimedia data and the identifier of the second multimedia sub-data may be sent to the receiving end, and the identifier of the second multimedia sub-data is configured to indicate the location of the second multimedia sub-data in the target multimedia data. The receiving end, after receiving the target multimedia data and the identifier, may extract the second multimedia sub-data from the target multimedia data according to the identifier, and display the second multimedia sub-data in the specified region of the display interface of the receiving end. In this way, with change of the location information, the sending end can update the first multimedia sub-data, the second multimedia sub-data and the identifier in real time, in the meantime, the receiving end can also update the second multimedia sub-data in real time, such that a dynamic and synchronous displaying effect can be achieved on the display interfaces of the sending end and the receiving end in a transmission process of the target multimedia data. 
     Specifically, taking the transmission instruction being triggered by swiping target multimedia displayed on the display interface of the sending end by the user with a finger as an example, the sending end may detect a location of the finger on the display interface, and divide the first multimedia sub-data and the second multimedia sub-data according to a displacement between a current location of the finger and an initial location of the finger when the finger starts swiping. As shown in  FIG.  5   , a point a is the initial location of the finger on the display interface, a point b is the current location of the finger on the display interface, the target multimedia data are a picture, according to a location relation between the point a and the point b, the picture may be divided into a Region A and a Region B, a sub-picture composed of pixels in the Region A is the first multimedia sub-data, and a sub-picture composed of pixels in the Region B is the second multimedia sub-data. In other words, the sub-picture corresponding to the Region A is displayed on the sending end, and the sub-picture corresponding to the Region B is displayed on the receiving end. 
       FIG.  6    is a flowchart of another method for processing multimedia data shown according to an example. As shown in  FIG.  6   , the method includes steps S 101  and S 102  and further includes the following steps. 
     In step S 107 , updated multimedia data sent by the receiving end are received, in which the updated multimedia data are generated after the receiving end performs specified processing on the target multimedia data. 
     In step S 108 , the updated multimedia data are displayed, and/or the updated multimedia data are saved. 
     For example, the receiving end, after receiving the target multimedia data, may perform specified processing, generate the updated multimedia data and then send the updated multimedia data to the sending end. The sending end may receive the updated multimedia data and display the updated multimedia data on the display interface of the sending end or may also save the updated multimedia data. The specified processing may be regarded as editing the target multimedia data, for example, may be adding a filter, a title, a special effect and other processing, or may also be cutting, compressing and other processing, which is not specifically limited by the disclosure. 
     Specifically, taking the sending end being a smartphone, the receiving end being a tablet computer, and the target multimedia data being a photo as an example, after the smartphone shoots a photo, if the user intends to edit the photo on the tablet computer, then the photo can be sent to the tablet computer, after the tablet computer receives the photo, the user may edit the photo on the tablet computer, and the edited photo is sent to the smartphone. The smartphone, after receiving the edited photo, may display the edited photo on the display interface or may also save the edited photo. 
       FIG.  7    is a flowchart of another method for processing multimedia data shown according to an example. As shown in  FIG.  7   , the method further includes the following steps. 
     In step S 109 , the communication connection with the receiving end is established. 
     In step S 110 , device login information of the receiving end is verified so as to determine whether the device login information of the receiving end matches device login information of the sending end. 
     Steps S 109  and S 110  are performed prior to steps S 101  and S 102 . Correspondingly, an implementation of step S 102  may be: the target multimedia data are sent to the receiving end through the communication connection under the condition that the device login information of the receiving end matches the device login information of the sending end. 
     For example, before information interaction is performed between the sending end and the receiving end, the sending end may firstly establish the communication connection with the receiving end through a preset communication protocol. The communication protocol may be wireless-Fidelity (Wi-Fi) protocol, a Bluetooth protocol and the like, a Zigbee protocol, 6LoWPAN protocol and the like, which is not specifically limited by the disclosure. After the sending end and the receiving end establish the communication connection, the sending end may receive the device login information of the receiving end, verify the device login information of the receiving end and judge whether the device login information of the receiving end matches the device login information of the sending end. The condition that the device login information of the receiving end matches the device login information of the sending end may be that the sending end and the receiving end log in the same user account, or may also be that the sending end and the receiving end belong to the same local area network, or may also be that there is a social relation (for example, being friends with each other) between a user account which the sending end logs in and a user account which the receiving end logs in, which is not specifically limited by the disclosure. Under the condition that the device login information of the receiving end matches the device login information of the sending end, the sending end may send the target multimedia data to the receiving end through the communication connection. In this way, the communication connection is established between the receiving end and the sending end in advance, transmission of the multimedia data can be performed fast and conveniently, and the data interaction efficiency is improved. 
     To sum up, in the disclosure, the sending end firstly obtains and displays the target multimedia data in response to the processing instruction and then sends the target multimedia data to the receiving end through the preset communication connection. The receiving end, after receiving the target multimedia data, displays the target multimedia data synchronously in the specified region of the display interface of the receiving end. In the disclosure, the multimedia data are sent to the receiving end through the preset communication connection such that the receiving end can display the target multimedia data synchronously, so the efficiency, the time-efficient performance and the convenience of transmission of the multimedia data are improved.
