Abstract

A method for acquiring a multimedia data stream includes establishing, by a terminal, a socket connection with a target camera device when a preset trigger event is triggered in the terminal and sending a transfer command to the target camera device through the socket connection when an event of starting preview is detected. The transfer command instructs the target camera to transfer the multimedia data stream. The method further includes receiving the multimedia data stream transferred by the target camera device and displaying the multimedia data stream in a specified preview interface.

Claims

1. A method for acquiring a multimedia data stream, comprising:

establishing, by a terminal, a socket connection with a target camera device when a preset trigger event is triggered in the terminal;

sending, when an event of starting preview is detected, a transfer command to the target camera device through the socket connection, the transfer command instructing the target camera to transfer the multimedia data stream;

receiving the multimedia data stream transferred by the target camera device; and

displaying the multimedia data stream in a specified preview interface.

2. The method according to claim 1, wherein establishing the socket connection includes:

acquiring a list of smart devices when an application for managing smart devices is started;

determining that the preset triggering event is triggered if the target camera device exists in the list and a connection state of the target camera device is an on-line state; and

establishing the socket connection with the target camera device.

3. The method according to claim 2, further comprising, after acquiring the list:

sending a starting command to the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are in a same network; and

updating the connection state of the target camera device.

4. The method according to claim 2, further comprising, after acquiring the list:

sending a starting command to a network device for accessing the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are not in a same network; and

updating the connection state of the target camera device.

5. The method according to claim 2, further comprising:

disconnecting the socket connection with the target camera device when the application for managing smart devices is closed.

6. The method according to claim 1, further comprising:

closing the specified preview interface when an event of pausing preview is detected; and

sending a pause command to the target camera device through the socket connection with the target camera device, the pause command instructing the target camera device to pause transferring the multimedia data stream.

7. The method according to claim 1, further comprising:

disconnecting the socket connection with the target camera device when the application for managing smart devices is closed.

8. A device for acquiring a multimedia data stream, comprising:

a processor; and

a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to;

establish a socket connection with a target camera device when a preset trigger event is triggered;

send, when an event of starting preview is detected, a transfer command to the target camera device through the socket connection, the transfer command instructing the target camera to transfer the multimedia data stream;

receive the multimedia data stream transferred by the target camera device; and

display the multimedia data stream in a specified preview interface.

9. The device according to claim 8, wherein the instructions further cause the processor to:

acquire a list of smart devices when an application for managing smart devices is started;

determine that the preset triggering event is triggered if the target camera device exists in the list and a connection state of the target camera device is an on-line state; and

establish the socket connection with the target camera device.

10. The device according to claim 9, wherein the instructions further cause the processor to:

send a starting command to the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are in a same network; and

update the connection state of the target camera device.

11. The device according to claim 9, wherein the instructions further cause the processor to:

send a starting command to a network device for accessing the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are not in a same network; and

update the connection state of the target camera device.

12. The device according to claim 9, wherein the instructions further cause the processor to:

disconnect the socket connection with the target camera device when the application for managing smart devices is closed.

13. The device according to claim 8, wherein the instructions further cause the processor to:

close the specified preview interface when an event of pausing preview is detected; and

send a pause command to the target camera device through the socket connection with the target camera device, the pause command instructing the target camera device to pause transferring the multimedia data stream.

14. The device according to claim 8, wherein the instructions further cause the processor to:

disconnect the socket connection with the target camera device when the application for managing smart devices is closed.

15. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a terminal, cause the terminal to:

establish a socket connection with a target camera device when a preset trigger event is triggered;

send, when an event of starting preview is detected, a transfer command to the target camera device through the socket connection, the transfer command instructing the target camera to transfer a multimedia data stream;

receive the multimedia data stream transferred by the target camera device; and

display the multimedia data stream in a specified preview interface.

16. The storage medium according to claim 15, wherein the instructions further cause the terminal to:

acquire a list of smart devices when an application for managing smart devices is started;

determine that the preset triggering event is triggered if the target camera device exists in the list and a connection state of the target camera device is an on-line state; and

establish the socket connection with the target camera device.

17. The storage medium according to claim 16, wherein the instructions further cause the terminal to:

send a starting command to the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are in a same network; and

update the connection state of the target camera device.

18. The storage medium according to claim 16, wherein the instructions further cause the terminal to:

send a starting command to a network device for accessing the target camera device if;

the connection state of the target camera device in the list is an off-line state, and

the terminal and the target camera device are not in a same network; and

update the connection state of the target camera device.

19. The storage medium according to claim 15, wherein the instructions further cause the terminal to:

close the specified preview interface when an event of pausing preview is detected; and

send a pause command to the target camera device through the socket connection with the target camera device, the pause command instructing the target camera device to pause transferring the multimedia data stream.

20. The storage medium according to claim 15, wherein the instructions further cause the terminal to:

disconnect the socket connection with the target camera device when the application for managing smart devices is closed.
