Please refer to fig. 1, which is a schematic structural diagram of an exemplary media streaming system of the present application, including a monitoring point device 11, a streaming media gateway 12, a VSM (Video Surveillance Management) server 13, and a mobile client 14, where the monitoring point device may be an NVR (Network Video Recorder) device or a monitoring camera, the monitoring camera is used to obtain a monitoring Video, and the NVR device is used to receive a media stream of the monitoring Video transmitted by the monitoring camera through a Network; the main functions of the streaming media gateway 12 are video distribution and network address translation (e.g., NAT translation); the VSM server 13 is used for detecting and analyzing the monitoring video, and has a function of a streaming media gateway; the mobile client 14 may be a mobile terminal such as a mobile phone, a tablet computer, or a notebook computer, and enables a user to check the media stream of the video monitoring through the login client. In practical applications, the mobile client 14 may access the VSM server 13 through an intranet access mode and an extranet access mode, for example, when the intranet is accessed, the mobile client 14 needs to input an intranet IP address of the VSM server 13, and the mobile client 14 and the VSM server 13 may log in the VSM server 13 only when they are under a local area network (as shown by the position of the mobile client on the left side in fig. 1); when the mobile client 14 inputs the extranet IP address of the VSM server 13 and the mobile client 14 uses a mobile network such as 4G/5G or a WiFi network of a public network (as shown by the location of the mobile client on the right side in fig. 1), the VSM server 13 can be logged in.
Referring to fig. 2, an interactive flowchart for determining a media streaming manner in the exemplary media streaming system of the present application is shown, which includes the following steps:
in this embodiment, the VSM server may receive a media stream request that requests a specified monitoring point device media stream and is sent by a mobile client, and obtain a source IP address and a destination IP address in the media stream request, where the source IP address is an IP address of the mobile client and the destination IP address is an IP address of the VSM server. The VSM server may determine an access manner in which the mobile client accesses the VSM server according to a destination IP address carried in the media stream request. Specifically, if the destination IP address in the media stream request is the intranet address of the VSM server, the VSM server may determine that the access mode of the mobile client accessing the VSM server is intranet access; if the destination IP address in the media stream request is the extranet address of the VSM server, the VSM server may determine the extranet access of the access mode in which the mobile client accesses the VSM server.
For example, as shown in fig. 3-1, the mobile client and the VSM server are in the same WiFi network, and it is assumed that the intranet IP address of the VSM server is 192.168.1.3, if the server IP address input when the mobile client accesses the VSM server is 192.168.1.3, it may be determined that the server IP address input by the mobile client is the intranet IP address of the VSM server, and since the VSM server and the mobile client are in the same WiFi network, the login message of the mobile client may be successfully sent to the VSM server, so that the login is successful. After the login is successful, the mobile client can send a media stream request to the VSM server, so that the VSM server can determine that the access mode of the mobile client is intranet access according to a destination IP address (192.168.1.3) carried in the received media stream request.
When the mobile client logs in the VSM server by using the external network IP address or domain name provided by the VSM server, the mobile client can successfully log in the VSM server only when the mobile client is in the 2G/3G/4G mobile network or in the wifi network (which may be the same as or different from the wifi network in which the VSM server is located) of the accessed public network, as shown in fig. 3-2, assuming that the internal network IP address of the VSM server is 192.168.1.3 and the external network IP address is 10.5.2.55, when the mobile client accesses the VSM server, the server IP address input is 10.5.2.55, and when the mobile client accesses the public network through the 2G/3G/4G mobile network or accesses the public network through the wifi network in which the public network is accessed, the login message of the mobile client can be successfully sent to the VSM server, so as to successfully log in. After the login is successful, the mobile client can send a media stream request to the VSM server, so that the VSM server can determine that the access mode of the mobile client is external network access according to a destination IP address (10.5.2.55) carried in the received media stream request.
As an embodiment, the VSM server may further determine the association information between the monitoring point device and the streaming media gateway by obtaining the identification of the monitoring point device in the media streaming request. Specifically, the VSM server locally records the corresponding relationship between the monitoring point device identifier and the streaming media gateway, so that the VSM server can determine whether the streaming media gateway corresponding to the monitoring point device identifier exists in the locally recorded corresponding relationship between the monitoring point device identifier and the streaming media gateway by acquiring the monitoring point device identifier in the media stream request, and if so, determine that the monitoring point device to be accessed by the mobile client is associated with the streaming media gateway; if not, determining that the monitoring point equipment to be accessed by the mobile client is not associated with the streaming media gateway.
In this embodiment, after the VSM server determines an access mode in which the mobile client accesses the VSM server and associated information between the monitoring point device to be accessed by the mobile client and the streaming media gateway, the transmission mode of the media stream may be further determined according to the access mode and the associated information.
As an embodiment, the VSM server is specifically configured to determine that a first target of the mobile client requesting a media stream is a monitoring point device, a second target of the mobile client is a streaming media gateway associated with the monitoring point device, and the second target is an updated target after the mobile client requests the first target for a media stream for a preset number of failures if an access mode of the mobile client is an intranet access and the monitoring point device is associated with the streaming media gateway; if the access mode of the mobile client is intranet access and the monitoring point equipment is not associated with a streaming media gateway, determining that the target of the mobile client for requesting the media stream is the monitoring point equipment; if the access mode of the mobile client is external network access and the monitoring point equipment is associated with a streaming media gateway, determining that the target of the mobile client for requesting the media stream is the streaming media gateway associated with the monitoring point equipment; and if the access mode of the mobile client is external network access and the monitoring point equipment is not associated with a streaming media gateway, determining that the target of the mobile client requesting the media stream is the VSM server.
After the VSM server determines the transmission mode of the media stream, the VSM server may notify the mobile client of the transmission mode. Specifically, if a first target of the mobile client requesting a media stream is a monitoring point device and a second target is a streaming media gateway associated with the monitoring point device, sending address information of the first target as the monitoring point device and address information of the second target as the streaming media gateway to the mobile client, so that the mobile client requests the media stream to the first target through the address information of the monitoring point device, and when the media stream requested to the first target reaches a preset failure number, requests the media stream to the second target through the address information of the streaming media gateway; if the mobile client requests the media stream to be the monitoring point equipment, the VSM server sends the address information of the monitoring point equipment to the client so that the client requests the media stream from the monitoring point equipment through the address information; if the mobile client requests a media stream to be a streaming media gateway associated with the monitoring point equipment, the VSM server sends address information of the streaming media gateway and address information of the monitoring point equipment to the client, so that the client is connected with the streaming media gateway through the address information of the streaming media gateway and sends a media stream request carrying the address information of the monitoring point equipment to the streaming media gateway; if the mobile client requests the media stream, the target of the media stream is the VSM server, the VSM server sends the specified address information built in the VSM server and the address information of the monitoring point equipment to the client, so that the client is connected with the VSM server through the specified address information and sends the media stream request carrying the address information of the monitoring point equipment to the VSM server.
The mobile client can request media stream from the corresponding target device according to the transmission mode informed by the VSM server.
As an embodiment, if a first target fed back to a VSM server is address information of a monitoring point device and a second target is address information of a streaming media gateway associated with the monitoring point device, the mobile client requests a media stream from the first target through the address information of the monitoring point device, and then requests the media stream from the first target through the address information of the streaming media gateway when a preset failure number of times is reached; if receiving the address information of the monitoring point device fed back by the VSM server, requesting a media stream from the monitoring point device through the address information of the monitoring point device, and for this situation, if the request fails, the mobile client may count the number of failures, and when the number of failures reaches a preset number, may display a prompt message for the user, and prompt the user to manually modify the media stream transmission mode, for example, the user may modify the media stream transmission mode by manually modifying the access mode, and the mobile client may also send a request failure message to the VSM server, so that the VSM server forwards the media stream requested by the mobile client to the mobile client; if receiving the address information of the streaming media gateway related to the monitoring point equipment fed back by the VSM server, connecting the streaming media gateway through the address information of the streaming media gateway, and sending a media stream request carrying the address information of the monitoring point equipment to the streaming media gateway; if the specified address information which is internally arranged in the VSM server and fed back by the VSM server and the address information of the monitoring point equipment are received, the VSM server is connected through the specified address information, and a media stream request carrying the address information of the monitoring point equipment is sent to the VSM server.
The following describes different transmission modes of media streams based on the interactive modes of the media stream transmission systems shown in fig. 4, fig. 5, fig. 6, and fig. 7.
Referring to fig. 4, an exemplary interaction flowchart for determining a media streaming manner according to the present invention includes a monitoring point device, a VSM server, a streaming media gateway, and a mobile client, and the specific method includes:

step 404, the VSM server informs the mobile client of the transmission mode;
the VSM server informs the mobile client of the transmission mode, specifically, the VSM server informs the mobile client of the address information of a first target, which is requested by the mobile client, of the monitoring point device, and informs a second target of the address information of the streaming media gateway, wherein the address information comprises an IP address and a port number;
step 405, the mobile client sends a media stream request to a first target (namely, a monitoring point device) according to the transmission mode;

step 410, the monitoring point device sends the requested media stream to the streaming media gateway;
step 411, after receiving the media stream sent by the monitoring point device, the streaming media gateway forwards the media stream to the mobile client.
In this embodiment, when the mobile client accesses the intranet and is associated with the streaming media gateway, the mobile client may first request the monitoring point device for the media stream directly, so as to reduce the process of forwarding the media stream by the intermediate device, so as to improve the transmission efficiency of the media stream, thereby reducing the load pressure of the streaming media gateway to the maximum extent, improving the transmission quality of the media stream, and reducing the user traffic cost. And the mobile client can send a media stream request to the streaming media gateway associated with the monitoring point device when the statistics of the failure times of sending the media stream by the monitoring point device reaches the preset times, so that the media stream transmission mode can be quickly adjusted, and the problem that the media stream cannot be normally obtained due to the time waiting when the media stream sent by the monitoring point device is lost is solved.

step 606, after receiving the media stream request, the streaming media gateway forwards the media stream request to the corresponding monitoring point device according to the address information of the monitoring point device carried in the media stream request;
step 607, the monitoring point device sends the requested media stream to the streaming media gateway;
step 608, the streaming media gateway receives the media stream sent by the monitoring point device and then forwards the media stream to the mobile client.
In this embodiment, when the mobile client accesses the external network and is associated with the streaming media gateway, the mobile client may directly send a media stream request to the streaming media gateway associated with the monitoring point device, and the streaming media gateway may forward the media stream of the monitoring point device.
Referring to fig. 7, an exemplary fourth interaction flowchart for determining a media streaming manner according to the present invention is shown, where the interaction flowchart includes a monitoring point device, a VSM server, and a mobile client, and the specific method includes:
step 701, accessing monitoring point equipment to a VSM server;
step 702, the mobile client accesses the VSM server through the external network IP address distributed by the VSM server and sends a media stream request to the VSM server, wherein the media stream request carries the equipment identifier of the monitoring point to be requested;
step 703, the VSM server determines that the access mode of the mobile client accessing the VSM server is external network access according to the destination IP address of the media stream request, and determines that the monitoring point device is not associated with a streaming media gateway according to the monitoring point device identifier in the media stream request, and then determines that the destination of the media stream requested by the mobile client is the VSM server according to the access mode and the associated information;
step 704, the VSM server notifies the mobile client of the transmission mode, specifically, the VSM server notifies the mobile client of the address information of the specified streaming media gateway in the VSM server and the address information of the monitoring point device;
step 705, the mobile client sends a media stream request to the VSM server according to the address information of the specified streaming media gateway in the VSM server, where the media stream request carries the address information of the monitoring point device;
step 706, after receiving the media stream request, the VSM server forwards the media stream request to the monitoring point device according to the address information of the monitoring point device carried therein;
step 707, the monitoring point device sends the requested media stream to the VSM server;
step 708, after receiving the media stream sent by the monitoring point device, the VSM server forwards the media stream to the mobile client.
In this embodiment, when the mobile client accesses the external network and does not associate with the streaming media gateway, the mobile client may directly send a media stream request to the VSM server, so that the VSM server may forward the media stream of the monitoring point device. Because the function of the streaming media gateway can be integrated in the VSM, the adoption of the mode of forwarding the media stream by the VSM can reduce the deployment of the streaming media gateway, thereby reducing the use cost of a user.
It should be noted that, in the above four cases, both the streaming media gateway and the VSM server may directly forward the received media stream sent by the monitoring point device to the mobile client, or transcode the media stream according to actual requirements and send the transcoded media stream to the mobile client.
As can be seen from the above embodiments, the present application may notify the transmission mode of the media stream of the mobile client according to the access mode of the mobile client and the situation that the monitoring point device is associated with the gateway, so that the mobile client may actually request the media stream in the most appropriate transmission mode, and may also change the transmission mode to ensure that the media stream may be normally transmitted when the transmission reaches the preset failure times. Compared with the prior art, the method and the device can avoid adopting a fixed mode to transmit the media stream, so that the mode of transmitting the media stream by the monitoring point device can be optimized.
