On the basis of the basic characteristics of the video network, one of the core ideas of the embodiments of the present invention is that if there are many audio interfaces on the video network terminal in the video conference, when the audio interface on the video network terminal needs to be switched, the video network terminal can flexibly switch the audio interface currently acquiring the audio to the audio interface corresponding to the audio interface switching instruction according to the audio interface switching instruction, and the switched audio interface is adopted to acquire audio data, so that the switching flexibility of the audio interface is improved, and the audio interface switching requirement of the user is met.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a data processing method of a video network according to an embodiment of the present invention is shown, where the video network includes a video network terminal.
The video network terminal may be a terminal that implements functions such as video conferencing or monitoring through a video network, for example, the video network terminal may be a mobile terminal, such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device (such as glasses, a watch, and the like).
The video network terminals participating in the video conference are called participant terminals, so that the video network terminals may include a plurality of participant terminals, and the plurality of participant terminals are in the same video conference. Each participant terminal may be configured with multiple audio interfaces, each audio interface having a matching audio connector, the types of audio interfaces including, but not limited to: a USB (Universal Serial Bus) Interface or a TRS (Tip Ring Sleeve) connector, a cardon Interface, and an HDIM (high definition Multimedia Interface) Interface; in addition, the audio interface of the participant terminal may also be a composite interface, including but not limited to a USB to cardon interface (i.e. the participant terminal does not have a cardon interface but has a USB interface, and the cardon interface is connected with the USB interface, so as to construct the USB to cardon interface).
For the audio interface and the matched audio connector, for example, the participant terminal may have a USB interface, and then the USB connector of the microphone may be plugged into the USB interface of the participant terminal, so that the participant terminal can collect audio data by using the microphone.
With the aid of the above-mentioned video networking terminal, the method may specifically include the steps of:
the audio interface switching instruction may be triggered by the participant terminal user performing an audio interface switching operation on the participant terminal, or may be received by the participant terminal from the control terminal side, which is not limited in the present invention.
In addition, it should be noted that the participating terminal that receives the audio switching instruction in the embodiment of the present invention is a video networking terminal in the video conference, that is, the method in the embodiment of the present invention may perform the audio interface switching operation on the video networking terminal that is performing the video conference service, and it is not necessary to first quit the video conference, manually perform the audio interface switching, and then participate in the video conference.
In addition, a plurality of participating terminals in the same video conference can be provided, so that a multi-party video conference is carried out.
In one example, a user of a certain participant terminal may trigger an audio interface switching instruction by operating conference control software of the participant terminal, so that the participant terminal may receive the audio interface switching instruction triggered by the user of the participant terminal.
in this step, the participant terminal may obtain the preset identification information of the first audio interface according to the audio interface switching instruction.
It should be noted that the relevant information of the first audio interface carried in the audio interface switching instruction may be preset identification information, or may be other information associated with the preset identification information. By means of the audio interface switching instruction it can be determined to which audio interface the currently in use audio interface of the participant terminal needs to be switched.
In addition, the number of the first audio interfaces to be switched to may be one or more. That is, in the present invention, when switching the audio interface of a certain participant terminal, the audio interface in use can be switched to any one or more other unused audio interfaces.
When the conference terminal is switched to a plurality of audio interfaces, the conference terminal can use the plurality of audio interfaces to collect audio information, and multi-channel audio output of the conference terminal in a video conference is realized.
a second audio interface corresponding to the second audio acquisition thread is different from the first audio interface;
in order to distinguish the audio interface before switching from the audio interface after switching, in the embodiment of the present invention, the audio interface of the participating terminal that is acquiring audio before switching the audio interface is referred to as a second audio interface, and the audio interface to be switched is referred to as a first audio interface.
Wherein the number of the second audio interfaces can be multiple.
Then to determine which audio interface is being used by the participant terminal to capture audio, the audio capture threads running in the participant terminal may be identified, where the audio capture threads corresponding to different audio interfaces are different, and the audio capture thread corresponding to the second audio interface may be referred to herein as a second audio capture thread. Therefore, the running second audio acquisition thread can be controlled to stop running in the step, so that the purpose of no longer using the second audio interface corresponding to the second audio acquisition thread to acquire audio data is achieved.
The execution sequence of step 502 and step 503 is not limited in the present invention.
wherein, the preset identification information includes but is not limited to one of the following: ID. Name, preset flag, etc.
It is mentioned above that each audio interface corresponds to an audio acquisition thread one-to-one, and in the embodiment of the present invention, the audio acquisition thread uniquely associated with the audio interface may be identified by using the preset identification information of the audio interface. Therefore, in this step, a first audio capturing thread may be started according to the preset identification information, for example, the audio capturing thread 1 is determined according to the ID of the first audio interface, so as to start the audio capturing thread 1.
Optionally, in an embodiment, when step 504 is executed, if the first audio interface of the participant terminal is connected to the corresponding first audio connector, the participant terminal may start a first audio acquisition thread according to the preset identification information.
In the foregoing, it is described that an audio interface needs to be used in cooperation with a corresponding audio connector to acquire audio through a certain audio interface, so in this embodiment, the participant terminal may further detect whether the first audio interface to be switched to is connected to the corresponding first audio connector, and if so, start a first audio acquisition thread corresponding to the first audio interface according to the preset identification information of the first audio interface.
On the contrary, if the first audio interface of the participant terminal is not connected with the corresponding first audio connector, the participant terminal user can be prompted to insert the first audio connector, so that the subsequent audio interface switching operation is completed.
Therefore, the first audio acquisition thread corresponding to the first audio interface is started according to the preset identification information of the first audio interface when the first audio interface to be switched of the terminal to be participated is detected to be connected with the corresponding first audio connector, so that the condition that the audio interface is failed to be switched can be avoided.
And 505, the participating terminal acquires audio information by adopting the first audio acquisition thread.
After the participant terminal starts the first audio acquisition thread, for example, the second audio interface is an HDMI interface, the HDMI interface is connected to a notebook computer, the first audio interface is a USB interface, and the USB interface is connected to a microphone. Before the above five steps of the embodiment of the present invention are performed, the participating terminal originally collects the audio data played by the notebook computer as the output audio of the participating terminal in the video conference. However, with the method of the embodiment of the present invention, when the participant terminal is in the video conference, the participant terminal may stop collecting the audio data from the notebook computer through the HDMI interface after receiving the audio interface switching instruction, and switch to collecting the audio data from the microphone through the USB interface, so that the audio data collected by the participant terminal from the microphone is used as the output audio of the participant terminal in the video conference.
Therefore, when the participant terminal is in the video conference, the participant terminal can acquire the preset identification information of the first audio interface to be switched to according to the received audio interface switching instruction, stop the second audio acquisition thread which is acquiring the audio, start the first audio acquisition thread corresponding to the preset identification information, and control the first audio acquisition thread to acquire the audio data, so that the switching from the second audio interface to the first audio interface of the participant terminal in the video conference is realized, and the first audio interface which needs to be switched to when the audio interface is switched can be dynamically changed according to the difference of the audio interface switching instruction, thereby improving the flexibility of audio interface switching and being capable of meeting the user requirements.
Optionally, in an embodiment, the video networking terminal further includes a control terminal.
The control terminal is also a video network terminal, but the control terminal is different from the participant terminal in that the control terminal does not participate in the video conference. Instead, the control terminal may control the video conference.
The controlled content includes but is not limited to the conference entering operation of the terminal of the video network, so that the terminal of the video network becomes a participant terminal;
the conference quitting operation is carried out on the participant terminals participating in the video conference, so that the participant terminals are recovered to be video networking terminals not participating in the video conference;
controlling the participant terminals to speak, for example, controlling the participant terminals 1, 2 and 3 to speak, and then outputting the audio data collected by the participant terminals 1, 2 and 3, so that the other participant terminals except the participant terminal receive the audio data;
controlling the participant terminal not to speak, for example, controlling the participant terminal 4 not to speak, if the audio interface of the participant terminal 4 collects audio, the collected audio data is not output to the video conference, and other participant terminals except the participant terminal 4 cannot receive the audio data;
and switching the audio interface used by the participating terminal.
Then, this embodiment focuses on the operation of the control terminal for switching the audio interface used by the participating terminal, in this embodiment, the control terminal is installed with the conference control software according to the embodiment of the present invention, and specifically, before step 101, the method according to the embodiment of the present invention may further include S601 to S603:
s601, the control terminal receives an audio interface switching request, wherein the audio interface switching request comprises target meeting participating terminal information and preset identification information of a first audio interface to be switched;
an administrator (i.e., a control terminal user) at the control terminal side can operate conference control software installed on the control terminal, so that the control terminal receives an audio interface switching request triggered by the administrator.
The audio interface switching request may include information about which participating terminal performs audio interface switching (i.e., target participating terminal information), and information about which audio interface the target participating terminal is currently using to switch to (i.e., preset identification information of the first audio interface).
The target participating terminal information may include, but is not limited to, name information, IP address information, ID information, and the like of the participating terminal, which may uniquely identify the participating terminal.
S602, the control terminal generates an audio interface switching instruction according to the audio interface switching request;
after receiving the audio interface switching request, the control terminal may generate an audio interface switching instruction according to preset identification information of the first audio interface in the audio interface switching request, where the audio interface switching instruction includes the preset identification information of the first audio interface.
The audio interface switching request is data which can be identified by the control terminal, the audio interface switching instruction is data which can be identified by each participating terminal, and the codes of the two data can be different.
S603, the control terminal responds to the audio interface switching request and sends the audio interface switching instruction to a target conference participating terminal corresponding to the target conference participating terminal information;
the control terminal can respond to an audio interface switching request triggered by an administrator to send the generated audio interface switching instruction to the target participating terminal corresponding to the target participating terminal information.
Then, on the basis of this embodiment, when step 101 is executed, it is embodied that the target participating terminal receives the audio interface switching instruction from the control terminal.
That is to say, the participant terminal in step 101 is the target participant terminal in this embodiment, and the audio interface switching instruction received by the participant terminal is from the control terminal, rather than the audio interface switching instruction triggered by the participant terminal user
Therefore, the method provided by the embodiment of the invention controls the switching of the audio interface of which participant terminal and the switching to which audio interface through the control terminal, compared with the method that each participant terminal controls the switching of the own audio interface, the method provided by the embodiment of the invention can avoid the disorder of the switching of the audio interface of each participant terminal, can realize the uniform control of the audio interface of each participant terminal, flexibly selects which audio interface or audio interfaces of which participant terminal to switch and which audio interface to switch to, and compared with the method that the audio interface to which audio interface is determined according to the priority of the audio interface, the method provided by the embodiment of the invention improves the switching flexibility of the audio interface.
Optionally, in an embodiment, before S601, the method according to an embodiment of the present invention may further include:
the control terminal acquires an audio interface list of each participating terminal in the plurality of participating terminals and the state of each audio interface in the audio interface list;
the control terminal can acquire the audio interfaces of the participating terminals for each participating terminal participating in the same video conference, so that an audio interface list is acquired for each participating terminal, and the audio interface list can comprise preset identification information of the audio interfaces.
In addition, the control terminal can also acquire the state of each audio interface of each participating terminal, wherein the state of each audio interface comprises an open state or a closed state;
the audio interface in the on state is that the participating terminal is running an audio acquisition thread corresponding to the audio interface, so as to acquire audio data;
the audio interface in the off state means that the participating terminal does not start the audio acquisition thread corresponding to the audio interface at present, and does not use the audio interface to acquire audio data.
The control terminal provides the audio interface list of each participating terminal and the state of each audio interface in the audio interface list to a control terminal user;
the control terminal can display the acquired audio interface list of each participating terminal and the state of each audio interface in each audio list on a screen in an interface mode, so that the audio interface list is provided for an administrator to view.
The administrator can know the state of each audio interface of each participant terminal by checking the interface, so that the administrator can control which participant terminal or terminals are switched with the audio interface, and the audio interface of the participant terminal is switched to which audio interface, thereby avoiding switching the audio interface which is originally in the open state to the open state again, and wasting operation resources.
Of course, the above-mentioned audio interface list of each participating terminal and the providing mode of the status information of each audio interface are not limited to the interface, and may also include graphics, audio, and the like, which is not limited by the present invention.

In this embodiment, when S601 is executed, the control terminal receives an audio interface switching request triggered by a user of the control terminal.
After the administrator knows the audio interface list of each participating terminal provided by the control terminal and the state of each audio interface in the audio interface list, the administrator can select which participating terminal to switch the audio interface, and select which audio interface in the on state that the participating terminal is using to switch to which audio interface in the off state originally.
Therefore, the control terminal may receive an audio interface switching request triggered by an administrator, where the audio interface switching request includes a target participant terminal selected by a user of the control terminal and preset identification information of a first audio interface selected from the audio interface list of the target participant terminal, where the first audio interface is in an off state.
Therefore, the control terminal of the embodiment of the invention obtains the audio interface list of each participating terminal in a plurality of participating terminals participating in the video conference and the state of each audio interface in each audio interface list and provides the audio interface list to the control terminal user, so that the control terminal user can conveniently and reasonably control the switching of the audio interfaces of the participating terminals according to the development condition of the video conference, the purpose of uniformly controlling the audio interfaces used by the participating terminals can be achieved, the audio interface switching of which participating terminal is flexibly selected and the audio interface to which the participating terminal is switched can be flexibly selected according to the requirements of the control terminal user, and the switching flexibility of the audio interface is improved.
Optionally, the video network further comprises a video network server, then after step 505, the method according to an embodiment of the present invention may further comprise:
if the participant terminal is in the speaking state, the participant terminal sends the audio information to the video networking server;
as described above, when the participant terminal is not in the speech state, the audio data collected by the audio collection thread corresponding to the audio interface in the open state of the participant terminal is not received by other participant terminals, and may be only buffered locally. Therefore, in this embodiment, if the participant terminal (i.e. the target participant terminal with the switched audio interface in the above embodiment) is in the speaking state, the participant terminal may send the audio information collected by the first audio collecting thread to the video network server.
Optionally, the video network server may distribute the audio data from the participant terminal to each of the other participant terminals in the same video conference as the participant terminal.
For example, the video conference includes a participant terminal 1, a participant terminal 2, and a participant terminal 3, for example, the target participant terminal is the participant terminal 1, and then the video networking server receives the audio data 1 collected by the microphone connected to the participant terminal 1 through the USB interface, and then the audio data 1 can be distributed to the participant terminal 2 and the participant terminal 3 in the video conference, so that the participant terminal 2 and the participant terminal 3 can both output the audio data 1, and the user at the participant terminal 1 is heard by the users at the other two participant terminals in the video conference through the words spoken by the microphones.
Therefore, the embodiment of the invention can switch the audio interface no matter whether the participant terminal switching the audio interface is in the speaking state or not, once the participant terminal is in the speaking state, the method of the embodiment of the invention can distribute the audio data collected by the switched audio interface of the participant terminal to the other participant terminal sides except the participant terminal in the video conference by means of the video networking server, so that users of other participant terminals can listen to the latest audio data collected by the audio interface switched by the participant terminal, and the video conference is conveniently and accurately executed.
