The application provides a method for acquiring a video picture, and as shown in fig. 1, the method describes a technical scheme by taking a cloud server as an execution subject. The method illustrated in fig. 1 mainly comprises steps S101 to S103, detailed as follows:
step S101: and before receiving an acquisition instruction of the video call message, establishing communication connection with the video equipment end through interaction with the video equipment end.
Different from the prior art that an intelligent terminal sends a video call message firstly, and the video call message triggers a cloud server to establish communication connection with a video equipment terminal, the technical scheme of the application is that before an acquisition instruction of the video call message is received, the communication connection with the video equipment terminal is established through interaction with the video equipment terminal.
As an embodiment of the present application, the implementation of step S101 can be implemented through step S1011 to step S1013, which are described as follows:
step S1011: and forwarding the early conference access message sent by the intelligent terminal to the video equipment terminal, wherein the early conference access message contains an instruction for establishing a conference in advance.
In the embodiment of the application, the cloud server receives the early conference information sent by the intelligent terminal, and then forwards the early conference information to the video equipment terminal, wherein the early conference information contains an early conference creation instruction for indicating that the video equipment terminal can create a video conference in advance. Here, the early conference Message is based on a protocol of Message Queue Telemetry Transport (MQTT). It should be noted that the early-joining message is sent to the cloud server through an application App installed on a smart terminal (e.g., a smart phone, a tablet computer, etc.), and the early-joining message does not need to be sent under the operation of a smart terminal user, but is sent to the cloud server in the background automatically by the application after the application is opened, and the user does not perceive the message.
Step S1012: and creating the video conference according to the message submitted by the video equipment terminal based on the pre-created conference instruction.
And after receiving the early conference information containing the early conference establishing instruction, the video equipment terminal interacts with the cloud server according to the early conference establishing instruction. Specifically, the implementation of step S1012 may be: the cloud server receives a video conference creation request sent by the video equipment terminal based on the pre-created conference instruction, then returns a video conference creation success notification and a video conference identifier to the video equipment terminal after the video conference is successfully created, the third step is that the cloud server receives a video conference joining request sent by the video equipment terminal according to the video conference identifier, and finally, the cloud server returns a video conference joining success notification to the video equipment terminal.
Step S1013: and receiving a message queue telemetering and transmitting an MQTT message sent by a video equipment terminal, wherein the MQTT message comprises the identification of the video conference and the identification of the video equipment terminal.
After receiving the notification that the video conference joining is successful, the video device side sends an MQTT message to the cloud server, wherein the MQTT message comprises information such as identification of the video conference, identification of the video device side, identification of the message and the like, and the cloud server receives the MQTT message, so that the cloud server has successfully established communication connection with the video device.
Step S102: and establishing communication connection with the intelligent terminal through interaction with the intelligent terminal.
As described above, when the cloud server successfully establishes the communication connection with the video device, the cloud server receives information including the identifier of the video conference, the identifier of the video device, the identifier of the message, and the like, which are returned by the video device, and accordingly, the cloud server can establish the communication connection with the intelligent terminal. Specifically, the implementation of step S102 may be: and forwarding a message containing information such as the identification of the video conference, the identification of the video equipment terminal and the identification of the message to the intelligent terminal, receiving a request for joining the video conference sent by the intelligent terminal according to the MQTT message, and returning a notification of successful joining of the video conference to the intelligent terminal, wherein the cloud server also successfully establishes communication connection with the intelligent terminal.
Step S103: and when an acquisition instruction of the video call message is received, forwarding the video stream to the intelligent terminal so as to display a video picture on the intelligent terminal.
Specifically, as an embodiment of the present application, when an acquisition instruction of a video call message is received, forwarding a video stream to an intelligent terminal, so as to display a video picture on the intelligent terminal, may be: when an acquisition instruction of the video call message is received, the acquisition instruction of the video call message is forwarded to a video equipment end, so that a video stream is pushed by the video equipment end; and forwarding the video stream pushed by the video equipment terminal to the intelligent terminal so as to display a video picture on the intelligent terminal.
After passing through steps S101 and S102, the cloud server has successfully established communication connections with the video device and the smart terminal, respectively. Therefore, when the acquisition instruction of the video call message is received, the cloud server can forward the acquisition instruction of the video call message to the video equipment end through the communication connection established between the cloud server and the video equipment end so as to push the video stream by the video equipment end; here, the instruction for obtaining the video call message may be sent to the cloud server by the smart terminal (or the application) after the user performs an operation on the smart terminal (for example, clicks a button provided on the user interface by the application).
As described above, since the early conference message in step S101 is automatically sent to the cloud server in the background, the user cannot perceive the sending process, in other words, since the user does not need to perform any manual operation, the completion processes of step S101 and step S102 cannot be perceived by the user, and therefore, it does not appear to the user that the communication connection between the cloud server and the smart terminal and the video device is established, that is, the user only starts to perceive the time of acquiring the video picture from step S103, or the user only starts to perceive an operation (for example, clicks a button provided on the user interface) of the smart terminal that the user performs an acquisition instruction corresponding to the video call message in mind, as the timing start time of acquiring the video picture.
After receiving an acquisition instruction of a video call message sent by the cloud server, the video device side pushes a video stream required to be acquired by the acquisition instruction to the cloud server through the communication connection established between the video device side and the cloud server. The cloud server forwards the video stream pushed by the video equipment terminal to the intelligent terminal through the communication connection established between the cloud server and the intelligent terminal so as to display the video picture on the intelligent terminal.
It is the time when the user starts sensing the acquisition of the video picture from step S103, and therefore, the user feels that it takes a particularly short time to acquire the video picture as compared with the related art. For example, according to the prior art, although the application also provides a button corresponding to the instruction for acquiring the video call message on the application installed on the smart terminal, the user cannot acquire the video picture in a short time after clicking the button, but the cloud server starts to establish the communication connection with the smart terminal and the video device after receiving the instruction for acquiring the video call message, assuming that the user clicks the button at 9:00:00, further assuming that the time for establishing the communication connection with the smart terminal and the video device by the cloud server is 8 seconds, according to the prior art, the cloud server needs to complete the establishment process of the communication connection with the smart terminal and the video device at 9:00:08, after the establishment of the communication connection is completed, the time for loading the video is generally 2 seconds, the whole process takes about 10 seconds, and in this process, the user is in a waiting state from 9:00:00 to 9:00:08, anxiety then develops. According to the technical scheme, when the user opens the application, the application actually sends the early conference information to the cloud server, the cloud server establishes connection with the video equipment and the intelligent terminal according to the early conference information, the moment when the application sends the early conference information to the cloud server to establish the connection with the video equipment and the intelligent terminal is 10:00:00, and the time consumed for the cloud server to establish the connection with the video equipment and the intelligent terminal according to the early conference information is 8 seconds, so that the cloud server completes the establishment process of the connection with the video equipment and the intelligent terminal at 10:00: 08; after the communication connection is established, it generally takes 2 seconds to load the video, and the whole process takes about 10 seconds. However, since sending the early-joining message to the cloud server by the application is an automatic and spontaneous process of the application in the background, the user does not know or feel the process of establishing the connection with the video device and the intelligent terminal by the cloud server, and therefore, although it also takes 8 seconds to establish the communication connection, it takes 10 seconds to complete the acquisition of the video picture, however, the user cannot perceive the video picture at all from 8 seconds of 10:00:00 to 10:00:08, so that the user thinks that the whole process of acquiring the video picture starts from the moment of 10:00:08, namely when a certain button operation provided by the user on the application interface, the application (or the intelligent terminal) sends an acquisition instruction of a video call message corresponding to the operation to the cloud server, the 10:00:10 is already finished, and the whole process only lasts for 2 seconds (the 2 seconds are the time consumption of video loading), so that the experience of the user is very good.
As can be seen from the above method for acquiring a video frame illustrated in fig. 1, communication connections with the video device and the intelligent terminal are respectively established before an acquisition instruction of a video call message is received, and when the acquisition instruction of the video call message is received, a video stream at the video device end is forwarded. The method comprises the steps that the video picture is acquired by the cloud server, the video equipment and the intelligent terminal, and the video picture is acquired by the cloud server.
