Abstract

The embodiment of the invention discloses a video evaluation method and a device. The method comprises: obtaining audio and video parameters, network transmission parameters and screen configuration parameters of the video; based on the audio and video parameters, network transmission parameters and screen configuration parameters, obtaining the video scoring output set by using the video perception evaluation model; obtaining the user experience score included in the rating output set as the result of the video evaluation. In this way, the effects of audio and video, network transmission andplaying screen on video user experience are considered comprehensively, and the video perception evaluation model is adopted to simplify the calculation complexity, improve the accuracy and efficiencyof video evaluation, and reduce the time cost.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video evaluation method and device. Background technique [0002] With the development of communication technologies, traditional voice calls are gradually replaced by video calls, such as Voice over Long Term Evolution (VoLTE) video calls and WeChat video calls. However, due to problems such as unclear video images, freezes, and long delays, the user experience is affected. Therefore, in order to determine the quality of the video at the receiving end, the evaluation of the user experience of the video at the receiving end has also become the focus of attention. [0003] Under the existing technology, the following methods are usually used to evaluate the user experience of the video at the receiving end: [0004] The first way is: through designated testers, in a specific test environment, score the quality of the video according to the preset test standards, and...
