Abstract

The invention relates to the technical field of the video conference, and specifically relates to a test method and device of video delay in a video conference. The method comprises the following steps: acquiring first video data obtained by decoding a to-be-tested first data message by a multi-point control unit and a to-be-tested second data message with a time stamp; decoding the to-be-tested second data message to obtain the second video data and the time stamp; computing based on a timestamp of the first video data and the time stamp corresponding to the second video data to obtain delayof the multi-point control unit. Through the method disclosed by the invention, the timestamp is added when decoding the received to-be-tested first data message, wherein the timestamp is the corresponding timestamp when performing the decoding by the multi-point control unit; the time stamp is added when performing media processing on the decoded video data, and the time stamp is the corresponding time in the media processing; the delay caused by the transmission of the data message in the network can be avoided based on the timestamp and the time stamp, and the method has relatively high reliability.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a method and device for testing video delay in video conferencing. Background technique [0002] With the development of the times and the progress of society, people's communication methods are undergoing earth-shaking changes. Video conferencing has gradually become a mainstream communication method. It is convenient and fast, and its intuitive image is deeply loved by everyone. Among them, the video conferencing in the central point mode is widely used. The so-called central point mode means that in a video conference, audio and video data is sent from the source terminal to the multipoint control unit, and then sent to the destination terminal after being processed by the multipoint control unit. However, audio and video data will inevitably consume a certain amount of time during the processing of the multi-point control unit, causing the video images of the sou...
