Embodiment Construction

[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0045] In the context of the above problems, in order to effectively and accurately test the audio and video synchronization performance of the video conference, especially the multimedia flow unit (because the synchronization performance of the terminal side can be evaluated through point-to-point communication tests, and there is no intuitive test method on the platform side) , the present invention proposes an audio and vid...

Abstract

The invention provides an audio and video synchronization performance test method and device, electronic equipment and a storage medium. The audio and video synchronization performance test method comprises the following steps: acquiring first audio and video data with a time mark sent by a source terminal and received by a multimedia through a stream unit; Obtaining second audio and video data which is used for being sent to a target terminal after the first audio and video data is processed by the multimedia through a streaming unit, wherein the second audio and video data has a time mark; And playing the first audio and video data and the second audio and video data through a video editing tool, and detecting the delay of audio and video and video synchronization performance before andafter the multimedia is processed by a streaming unit according to the time marks of the first audio and video data and the second audio and video data and audio and video data feature matching. According to the method and the device provided by the invention, the audio and video synchronization performance test of the multimedia through the streaming unit side is realized.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to an audio and video synchronization performance testing method, device, electronic equipment, and storage medium. Background technique [0002] Multimedia technology has developed rapidly, and the application of multimedia systems has penetrated into various fields of human life, such as communications, industry, medicine, teaching, etc., bringing great convenience to people's lives. [0003] Video conferencing is a multimedia communication technology that allows people in different places to realize "real-time, visual and interactive" through a certain transmission medium. Modern video conferencing systems are mainly used for audio and video meetings. In a video conference, audio, video and video data are collected and sent to a multipoint control unit (MCU) after being processed by the source terminal, and then forwarded to the target terminal after processing. However, in...
