Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the invention belong. The terms (such as those defined in commonly used dictionaries) will be interpreted as having a meaning that is the same as the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in connection with the various embodiments of the invention.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a music playing control method applied to a first device according to an embodiment of the present application is shown in fig. 1, where the method mainly includes:
step S101 of transmitting a control request corresponding to a second music playing application in a second device to the second device via a preset communication channel.
The preset communication channel is a dedicated communication channel for connection and data transmission between the second device and the first device. Before a preset communication channel between the first device and the second device is established, whether the first device and the second device are both preset type operating systems, such as an Android system or an iOS system, can be judged. If the first equipment and the second equipment are both the preset type operating systems, a preset communication channel is established through a TCP/IP Socket protocol or an Rfcomm protocol; if the first device and/or the second device is not the preset type of operating system, a preset communication channel is established through a TCP/IP Socket protocol. Most of the existing mobile terminal control software needs to be remotely controlled under the same operating system, such as android control android and iOS control iOS, so that the existing mobile terminal control software has a large limitation. According to different preset types of operating systems, different protocols are adopted to establish corresponding preset communication channels for data transmission, and good compatibility among devices can be achieved.
A connection is required before a preset communication channel is established between the first device and the second device. The manner in which the first device is connected to the second device includes, but is not limited to, bluetooth and local area networks. In the Bluetooth mode, selecting a second device from a connectable device list displayed by the first device to connect; in the local area network mode, the connection can be performed by inputting the IP address of the second device into the control interface of the first device. After the first device sends a control request to the second device, if the second device allows control, a preset communication channel between the first device and the second device is established according to the technical means.
After the first device and the second device establish the preset communication channel, the user clicks the first music playing application on the first device to enter the corresponding display interface, and a control request can be sent to the second device according to user input or automatically. The control request sent by the first device is for requesting control of a second music playing application running in the second device. In particular, the types of the first music playing application and the second music playing application may be different applications. The account information associated with the different types of music playing applications is different, for example, the second music playing application logs in to a member account, and the first music playing application logs in to a non-member account, so that a user can play music files which are not associated with and stored in the first music playing application on the first music playing application by controlling the second device and acquiring the music data associated with the second music playing application through the technical means.
Step S102, receiving current playing information of the second music playing application returned by the second device, where the current playing information includes a music file list and playing states of all music files in the music file list.
After the first device sends a control request to the second device and the second device allows control, the first device receives a music file list of the second music playing application and playing states of all music files in the music file list, wherein the number of the music file lists is at least one. For example, there are a plurality of music file lists such as "history play" and "favorite music" on the second music play application, each of which includes 10 pieces of song display information, and the second music play application is playing the 2 nd song of "favorite music". Then the first device receives the following types of data: a. the two music file lists each include 10 song display information; b. a first type of play state: the second music playing application is playing the 2 nd song in the favorite music; c. the second type of playing state, i.e. the other music files in the second music playing application are in an unplayed state.
Step S103, sending a play control instruction corresponding to the current play information to the second device.
In the implementation, the first device displays the current playing information of the second music playing application on the display interface of the first music playing application, for example, three types of data, namely a, b and c in step S102, so that the user performs music playing control on the second music playing application according to the current playing state of the second music playing application.
Compared with the existing remote control method, the method only analyzes and executes the data sent by the second device, and screen mirroring is not needed. Therefore, in the application, the first device and the second device execute different instructions or operations during control, and operation conflict cannot be generated to influence the other device.
Step S104, receiving, through the preset communication channel, an audio file in a second format returned by the second device based on the play control instruction, and converting the audio file into an audio file in a first format.
In implementation, a target data packet returned by the second device based on the play control instruction can be received through a preset communication channel, wherein the target data packet corresponds to the audio file in the second format. And then judging whether the target data packet received in the preset time is complete or not. If the target data packets received within the preset time are complete, converting all the target data packets into audio files in a first format; if the target data packet received within the preset time is incomplete, outputting a receiving abnormal signal. Because the first music playing application running on the first device and the second music playing application running on the second device may be of different types, the audio file formats that the two types of music playing applications can receive or play may also be different, and it is necessary to convert the audio files of the two different formats.
In specific implementation, the method can further comprise the following steps of judging whether the target data packet received in the preset time is complete: the method comprises the steps of firstly obtaining marking information contained in a last target data packet received within preset time, wherein the marking information comprises the sequence of the current target data packet in all target data packets and the number of all target data packets. And then judging whether the sequence of the current target data packet in all the target data packets is the same as the number of all the target data packets. If the target data packets are the same, judging that the target data packets received in the preset time are complete; if the target data packets are different, the incomplete target data packets received in the preset time are judged.
Step S105, controlling the first music playing application in the first device to play the audio file in the second format.
The first device may also receive current volume data associated with the audio file while receiving the audio file returned by the second device. By the technical means, the first device can not only play the second device according to the received current playing information of the second music playing application, but also further receive the audio file returned by the second device according to the playing control instruction. By playing the audio file with the corresponding volume size on the first device, the user can more intuitively feel the sound size of the music played on the second device, so that the user can send more accurate music playing control to the second device through the first device.
Referring to fig. 2, a music playing control method applied to a second device according to an embodiment of the present application is shown in fig. 2, where the method mainly includes:
step S201, a first device receives a control request via a preset communication channel, where the preset communication channel is a dedicated communication channel between the second device and the first device, and the control request indicates to control a second music playing application in the second device.
In practice, there may be situations where multiple first devices control the same second device within the same time frame. At this time, the second devices simultaneously connected to the plurality of first devices may respectively establish preset communication channels with the respective first devices.
Step S202, sending current playing information of the second music playing application to the first device, where the current playing information includes a music file list and playing states of music files in the music file list.
Step S203, receiving a play control instruction sent by the first device and corresponding to the current play information.
The specific implementation process of step S202 and step S203 may refer to step S102 and step S103, which are not described in detail herein.
Step S204, sending, to the first device, an audio file in a second format corresponding to the play control instruction through the preset communication channel.
In the implementation, after the second device establishes the corresponding preset communication channels with the plurality of first devices, the corresponding audio files can be sent through the corresponding preset communication channels of the first devices respectively. When the number of the preset communication channels is greater than one, at the same time point, the second device may receive a plurality of play control instructions, and at this time, it is necessary to further determine the priority order among the play control instructions, and respond to the corresponding play control instructions according to the priority order. The method comprises the following specific steps: if the number of the received play control instructions is greater than one, judging whether each play control instruction conflicts or not; if not, sending the audio file in the second format corresponding to the playing control instruction to the corresponding first equipment through each preset communication channel; if so, sending the audio file in the second format corresponding to the playing control instruction to the first device with the highest priority.
The priority order of each play control instruction may be associated with a corresponding permission level of the first device. For example: after the second device allows the first devices to control, each first device may be assigned a permission level value, where the higher the permission level value, the higher the priority order of its corresponding play control instruction, which is not specifically limited herein.
In particular, the second device may send the audio file in the second format to the first device in the form of a target data packet. Tag information may be added to each of the target data packets, the tag information including an order of a current target data packet among all of the target data packets and a number of all of the target data packets, and then each of the target data packets is transmitted to the first device in order based on a preset communication channel. For example, if the data corresponding to the audio file is divided into 10 target data packets and sent sequentially, the first target data packet will have a subscript 1, and information of 10 target data packets in total, and so on. When the subscript of the last target packet received by the first device reaches 10, it represents that the audio file received by the first device is complete.
Before dividing the audio file in the second format into a plurality of data packets, it may be determined whether the length of the initial target data corresponding to the audio file is greater than the maximum data length allowed to pass through the preset communication channel. If the length of the initial target data is greater than the maximum data length allowed to pass through the preset communication channel, dividing the initial target data into at least two target data packets with the length smaller than the maximum data length; if the length of the initial target data is smaller than or equal to the maximum data length allowed to pass through the preset communication channel, determining the initial target data as a target data packet.
According to the music playing control method, according to different preset types of operating systems, different protocols are adopted to establish corresponding preset communication channels for data transmission, and good compatibility among devices can be achieved. The first device in the application analyzes and executes the data sent by the second device, screen mirroring is not needed, different instructions or operations are executed when the first device and the second device are controlled, and operation conflicts are not generated to influence the other device. And the second equipment can respectively establish preset communication channels with the first equipment, and respectively send corresponding audio files through the preset communication channels, so that the control of the second equipment by the first equipment is realized.
