Referring to fig. 2, fig. 2 is a schematic flow chart of a method for transmitting streaming media data according to an embodiment of the present invention. The main execution body of the method for transmitting the streaming media data in this embodiment is the server. The method of transmitting streaming media data as shown in fig. 2 may include:
s101: when acquiring streaming media data request information sent by a terminal, generating a data session identifier corresponding to each piece of streaming media data request information; the data session identifier is used for identifying a data session corresponding to the streaming media data request information.
The terminal sends the streaming media data request information to the server, and the server receives the streaming media data request information sent by the terminal. When only one piece of streaming media data request information is sent by the terminal, the server may generate a data session identifier for identifying a data session corresponding to the streaming media data request information, with respect to the streaming media data request information. In this embodiment, in order to enable the server and the terminal to perform multiple unrelated data sessions simultaneously, that is, the server and the terminal transmit multiple unrelated streaming media data simultaneously, when receiving at least two different streaming media data request messages sent by the terminal, the server generates a data session identifier corresponding to each streaming media data request message; the data session identifier is used to identify a data session corresponding to the streaming media data request information. It can be understood that when the server acquires the streaming media data request information, a data session identifier is generated, and the session identifier can identify a data session corresponding to the streaming media data request information. The data session may be understood as data interaction between the server and the terminal for the streaming media data request information, that is, the terminal sends the streaming media data request information to the server, and the server gives a response and transmits corresponding streaming media data to the terminal.
Each data session identifier uniquely identifies the data session corresponding to the streaming media data request information, the data session identifier may be set by the user or randomly generated by the server, and the form of the data session identifier may be a number, a character, or a combination of a number and a character, and the like, which is not limited herein.
S102: and sending the data session identifier corresponding to each piece of streaming media data request information to the terminal based on the equipment identifier information of the terminal.

When the terminal sends the streaming media data request information, the terminal can carry the equipment identification information of the equipment, and the server obtains the equipment identification information. And the server sends the streaming media data request information and the data session identification corresponding to the streaming media data request information to the terminal based on the equipment identification information of the terminal. Further, the server may also obtain response information corresponding to the streaming media data request information, and send the streaming media data request information, the data session identifier corresponding to the streaming media data request information, and the response information to the terminal based on the device identifier information of the terminal.
S103: and acquiring the streaming media data corresponding to each piece of streaming media data request information.
And the server acquires the streaming media data corresponding to each piece of streaming media data request information. Specifically, different streaming media data corresponding to different streaming media request information are pre-stored in the server; the server can search the streaming media data corresponding to the request information according to different streaming media data request information. For example, the streaming media data request information requests a type of video data, and the corresponding streaming media data is video data; the streaming media data request information requests audio data, and the corresponding streaming media data is the audio data; the streaming media data request information requests a picture data, and the corresponding streaming media data is the picture data; the description is given for illustrative purposes only and is not intended to be limiting.
S104: and sending the data session identifier corresponding to each piece of streaming media data request information and the streaming media data to the terminal based on the equipment identifier information of the terminal.
And the server sends the data session identification and the streaming media data corresponding to each streaming media data request message to the terminal based on the equipment identification information of the terminal. Specifically, each piece of streaming media data request information corresponds to a data session identifier, each piece of streaming media data request information also has streaming media data corresponding to the streaming media data request information, and the server sends the data session identifier corresponding to the streaming media data request information and the streaming media data corresponding to the streaming media data request information to the terminal based on the equipment identifier information of the terminal; further, the server may also associate the data session identifier corresponding to the streaming media data request information with the streaming media data corresponding to the streaming media data request information, and send the associated data session identifier and the streaming media data to the terminal based on the device identifier information of the terminal.
Further, in order to meet different requirements of the user and change the attribute of the streaming media data in time, S104 may include S1041-S1042, which are as follows:
s1041: when an attribute modification request containing a data session identifier sent by the terminal is acquired, modifying the attribute of the streaming media data corresponding to the streaming media data request information associated with the data session identifier.
The attribute modification request sent by the terminal is used for requesting the server to modify the attribute of the streaming media data. The terminal sends an attribute modification request containing the data session identifier to the server, and when the server receives the attribute modification request sent by the terminal, the server modifies the attribute of the streaming media data corresponding to the streaming media data request information associated with the data session identifier.
Specifically, the data session identifier has streaming media data request information corresponding thereto, and the server may search for the corresponding streaming media data request information according to the data session identifier in the attribute modification request, search for the corresponding streaming media data according to the streaming media data request information, and modify the attribute of the streaming media data to the attribute included in the attribute modification request.
For example, when streaming media data is used to form an image and the attribute modification request wants to request the server to modify the resolution of the streaming media data, the server modifies the resolution of the corresponding streaming media data; when the attribute modification request wants to request the server to modify the audio format of the streaming media data, the server modifies the format of the corresponding streaming media data; the description is given for illustrative purposes only and is not intended to be limiting.
S1042: and sending the data session identification and the streaming media data with the modified attributes to the terminal based on the equipment identification information of the terminal.
And the server associates and sends the data session identification and the stream media data with the modified attribute to the terminal based on the equipment identification information of the terminal. Specifically, the server acquires the streaming media data with the modified attribute, sends the streaming media data with the data session identifier in the attribute modification request and sends the information to the terminal based on the equipment identifier information of the terminal; further, the attribute modification request can also be associated with the data session identifier in the attribute modification request, and the associated data can be sent to the terminal based on the device identification information of the terminal. When receiving the data session identifier and the stream media data with the modified attributes sent by the server, the terminal can identify which data session corresponds to the data session identifier according to the data session identifier, can know which stream media data request information the stream media data with the modified attributes aim at according to the data session identifier, and then plays the stream media data with the modified attributes on a corresponding playing interface.
Further, in the middle of data transmission between the server and the terminal, the terminal may also send an attribute modification request including a data session identifier to the server, and the server receives the attribute modification request; acquiring streaming media data request information corresponding to the data session identifier according to the data session identifier, and searching corresponding streaming media data which are not sent to the terminal according to the streaming media data request information; and modifying the attribute of the streaming media data which is not sent according to the content of the attribute modification request, associating the streaming media data with the data session identifier after the attribute is modified, and sending the associated data to the terminal based on the equipment identifier information of the terminal. The server receives the attribute modification request, modifies the attribute of the streaming media data, and sends the streaming media data with the modified attribute to the terminal.
In the embodiment of the application, the server generates corresponding data session identifiers for different streaming media data request information, and the data session identifiers can identify data sessions corresponding to the streaming media data request information; when the server transmits the streaming media data corresponding to the streaming media data request information to the terminal, the streaming media data can be transmitted in the data session corresponding to the data session identifier, so that the server and the terminal can simultaneously perform a plurality of unrelated data sessions, namely, the server and the terminal can simultaneously transmit a plurality of unrelated streaming media data, the transmission speed of the streaming media data is improved, network resources are saved, and the playing quality of the streaming media data is improved. And the server can receive the attribute modification request, modify the attribute of the streaming media data and send the streaming media data with the modified attribute to the terminal, and in the whole process, the data session between the server and the terminal does not need to be interrupted, so that the efficiency and the quality of streaming media data transmission are ensured.
Referring to fig. 3, fig. 3 is a schematic flowchart of a method for transmitting streaming media data according to another embodiment of the present invention. The main execution body of the method for transmitting the streaming media data in this embodiment is the server.
The differences between the embodiment of the present embodiment and the embodiment corresponding to fig. 2 are S201, S205 to S209, where S202 to S204 in the present embodiment are completely the same as S101 to S103 in the embodiment corresponding to fig. 2, and refer to the description of S101 to S103 in the embodiment corresponding to fig. 2, which is not repeated herein.
In order to accurately and quickly transmit the streaming media data and improve the playing quality of the streaming media data, the embodiment may further include S201, which is specifically as follows:
s201: when a transmission link connection request sent by the terminal is received, a data transmission link between the terminal and the terminal is established; the data transmission link is used for transmitting data to the terminal.
Before data transmission, the terminal and the server establish a data transmission link, and stream media data information, signaling, response information, request information and the like can be transmitted through the data transmission link. Specifically, the terminal sends a transmission link connection request to the server, and when the server receives the request, the server establishes a data transmission link with the terminal based on the device identification information of the terminal.
Further, in order to distinguish streaming media data in different data formats, the speed of identifying different streaming media data by the terminal is increased, and S205 is further included after S204, specifically as follows:
