In addition, a driver module may also be added to the operating system when the application 254 is installed in the mobile terminal 200.

The program for executing the method 300 for acquiring a media stream resource provided by the embodiment of the present invention is one of the applications 254. In some embodiments, the mobile terminal 200 is configured to perform the method 300 for acquiring a media stream resource according to the present invention.

Fig. 3 shows a flowchart of a method 300 for acquiring a media stream resource, which is suitable for being executed in a mobile terminal, and in particular, can be executed in an application of the mobile terminal, such as a live video application, in which case the media stream may be a live video stream suitable for being played in a live broadcast room. As shown in fig. 3, the method begins at step S320.

In step S320, an obtaining route of the current media stream resource and a CDN node corresponding to the route are determined.

Usually, there are multiple lines in the live broadcast room, such as a main line, a standby line, an ultra-clear line, and a high-definition line, and each line has a corresponding CDN node and a CDN service provider, that is, each line can provide resources for the corresponding CDN service provider. For example, line one may be a CDN of a satellite domain service provider, line two may be a CDN of a wire speed service provider, and line three may be a CDN of an Tencent service provider. The user can independently select which line is used after entering the live broadcast room, and the live broadcast room can also switch default lines for the user according to the current network environment and the user attribute. If the user is a member of a service provider (e.g., a member in flight) but the line provided by the service provider is an alternate line, the present invention automatically switches the line and CDN provided by the service provider for the user.

Subsequently, in step S340, the CDN node is used as an obtaining source of the media stream resource, and the media stream resource is obtained therefrom and played, that is, the stream playing is pulled from the CDN node.

Subsequently, in step S360, in response to the user turning on the P2P resource acquisition mode, a P2P service interface corresponding to the CDN node is searched.

According to one embodiment, the P2P resource acquisition mode may be automatically turned on when the number of live rooms reaches a predetermined value, wherein the predetermined value may be 100, but is not limited thereto. Certainly, after the user enters the live broadcast room, the media stream resource in the initial period may be obtained in the CDN resource obtaining mode, and after a predetermined time (e.g., 3min) is reached, whether to start the P2P resource obtaining mode is determined according to whether the number of people in the current live broadcast room reaches a predetermined value. That is, when the live broadcast room is just opened, no matter whether the number of people in the live broadcast room meets a preset value or not, a section of media stream resource is acquired in a CDN resource acquisition mode, and then switching is performed as required. Therefore, the fluency of the initial media resource acquisition of the user can be ensured, the bandwidth can be saved in the subsequent media resource acquisition, and the user experience is integrally improved.

According to one embodiment, when searching for a P2P service interface corresponding to a CDN node, a configuration file of an application may be obtained from a server, where the configuration file defines a P2P service interface corresponding to each CDN node, and a P2P service interface corresponding to the CDN node is searched for from the configuration file. Wherein the server may generate the configuration file according to the following method: according to the network connectivity and the bandwidth structure between the CDN nodes and the P2P, the P2P service interface corresponding to each CDN node is determined, and the association relationship between each CDN node and the corresponding P2P service interface is generated in a configuration file.

Fig. 4A and 4B respectively show schematic diagrams of configuration files according to an embodiment of the present invention, where the configuration files include a main line available in a current live broadcast room, one or more standby lines, a CDN corresponding to each line, and a P2P service interface corresponding to each CDN. For example, in fig. 4A, main ═ 2_3 represents that the main line of the live broadcast room is a CDN of a network sink, slaveflag ═ 14_29 represents that the standby line is a CDN of flight, and then 2_3 ═ xy and 14_29 ═ xy are obtained from P2pConf (P2P configuration list), that is, both the main line and the standby line use P2P provided by the star domain service provider. Thus, no matter which line the current line is, the last P2P switch is to the P2P of the satellite domain service provider. In addition, a state table whether each P2P service provider provides P2P service is also maintained in the configuration file, where tx _ stat (flight P2P), ws _ stat (network speed P2P), xy _ stat (star field P2P), kcg _ stat (jinshan P2P), a value of 1 represents that the P2P service of the P2P service provider can be used, and a value of 0 represents that the service is not available.

In addition, each live broadcast room has a corresponding configuration file, and the server can also store the room identifier of each live broadcast room and the corresponding configuration file, so that the room identifier of the current live broadcast room can be obtained, and the configuration file of the current live broadcast room in the application can be obtained from the server according to the room identifier. Wherein the room identifier comprises at least one of a room number, a room name and a main play number. When the user enters the live broadcast room, the client acquires the configuration file from the server in a network request mode, and the network request can comprise at least one of an entering room number, a main broadcast identification, a room type, a room classification name, a room unique mark and a room number.

The following is a network request and its included request parameters:

subsequently, in step S380, the obtaining source of the media stream resource is switched from the CDN node to the determined P2P service interface, and the media stream resource is obtained from the P2P service interface for playing. That is, after the P2P resource obtaining mode is started, the media stream resource is not obtained from the original CDN, but is obtained from the P2P service interface corresponding to the CDN for playing, so as to save bandwidth. The media stream resource is obtained from the P2P service interface, which may be in a conventional manner, and the present invention is not limited thereto.

According to one embodiment of the invention, the server may generate the configuration file according to the following method: according to the network connectivity and the bandwidth structure between the CDN nodes and the P2P, the P2P service interface corresponding to each CDN node is determined, and the association relationship between each CDN node and the corresponding P2P service interface is generated in a configuration file. In addition, the server stores the room identifier of each live broadcast room and the configuration file corresponding to the room identifier, and the CDN determining module 520 is adapted to obtain the room identifier of the current live broadcast room, and obtain the configuration file of the current live broadcast room in the application from the server according to the room identifier. Wherein the room identifier comprises at least one of a room number, a room name and a main play number. In addition, the P2P resource acquisition mode is turned on when the number of live room people reaches a predetermined value, which may be, for example, 100, although not limited thereto.

The P2P resource obtaining module 580 is adapted to switch the obtaining source of the media stream resource from the CDN node to the P2P service interface, and obtain the media stream resource from the P2P service interface for playing.
