And 106, generating participant identifications according to the audio data of the participants.
The participant id is a name or number of a participant for distinguishing different participants in the video conference.
In the embodiment of the invention, the corresponding participant identification can be generated according to the audio data of each participant so as to distinguish different participants participating in the video conference. Specifically, the audio data of my party and the other party may be extracted from the video stream data, and then the corresponding participant identifier may be generated according to the audio data, for example, the participant identifier "my party" may be generated according to the audio data of my party, and the participant identifier "other party" may be generated according to the audio data of the other party, where the number of the other parties may be one or more, and when the number is two or more, the participant identifiers "other party 1" and "other party 2" … … may be generated.
And step 108, displaying the participant identification.
In embodiments of the present invention, participant identities may be displayed. Specifically, when video stream data of the video conference is played, a corresponding participant identifier may be played at a specified position in the video conference interface, for example, the participant identifier may be displayed below the played video stream data, or the participant identifier may be displayed on the right side of the played video stream data.
For example, assuming that the video conference is a three-party conference, and the audio data of my party, the counterpart 1, and the counterpart 2 are extracted from the video stream data of the video conference, the participant identifiers "my party", "counterpart 1", and "counterpart 2" may be generated according to the audio data, and then sequentially displayed below the video conference interface according to the speaking sequence of the participants, and assuming that the speaking sequence is the counterpart 1, my party, counterpart 2, and my party, the participant identifiers are displayed as "counterpart 1, my party, counterpart 2, my party".
In the video processing method, the audio data of each participant is extracted from the video stream data of the video conference to be processed, the participant identifier is generated according to the audio data of each participant, and then the participant identifier is displayed.
