4. The method of claim 1, wherein sending a target message to the first device comprises:
determining address information of the third device;
and generating the target message based on the address information of the third equipment, and sending the target message to the first equipment.
5. An apparatus for processing media information, comprising:
the receiving module is used for receiving a first request sent by first equipment, wherein the first request is used for requesting to acquire media information acquired by second equipment in real time;
a sending module, configured to send a target message to the first device when it is determined that a third device exists, where the third device is a device that is currently acquiring the media information acquired by the second device in real time, and the target message is used to instruct the first device to acquire the media information from the third device;
wherein, the sending module includes: the acquisition unit is used for acquiring a target linked list, wherein the target linked list is a linked list generated according to an initiating device of a second request received by the second device; a determining unit, configured to determine that the third device exists in the target linked list when it is determined that the target linked list includes a device currently acquiring the media information acquired by the second device in real time; a sending unit, configured to send the target message to the first device;
the apparatus is further configured to: under the condition that it is determined that the target linked list includes a device currently acquiring the media information acquired by the second device in real time, after it is determined that the third device exists in the target linked list, a subsequent device of the third device in the target linked list is a fourth device, and after the first request is received, a first connection is disconnected, and a second connection and a third connection are generated, wherein the first connection is a connection in which the fourth device acquires the media information from the third device, the second connection is a connection in which the fourth device acquires the media information from the second device, and the third connection is a connection in which the first device acquires the media information from the third device; detecting the number of connections currently keeping acquiring the media information with the second equipment; and under the condition that the connection number is larger than or equal to a preset threshold value, disconnecting the second connection and generating a fourth connection, wherein the fourth connection is a connection for acquiring the media information from the first equipment by the fourth equipment.
6. A computer-readable storage medium, in which a computer program is stored, wherein the computer program is arranged to perform the method of any of claims 1 to 4 when executed.
7. An electronic device comprising a memory and a processor, wherein the memory has a computer program stored therein, and the processor is configured to execute the computer program to perform the method of any of claims 1 to 4.
