Problems solved by technology

[0008] However, using the second method, firstly, the recorded video needs to be post-processed, which will also cause video distortion, and secondly, since screen recording will occupy a large amount of system resources, it will have a certain impact on video communication , thereby reducing the quality of the video received by the receiving end. Further, screen recording has higher requirements on the configuration of the receiving end device, which increases the hardware cost

Abstract

The invention discloses a video restoration method and device, and the method comprises the steps: obtaining video information uploaded by a receiving end; decoding the video information to obtain decoded information, wherein the decoded information includes load information and data packet header information; performing recombination processing of the load information to obtain a decoded video, and performing the sequence analysis of the packet header information to obtain video frame loss information; carrying out the frame loss compensation processing of the decoded video based on the videoframe loss information to obtain a restored video. Therefore, the device does not need additional equipment, reduces software and hardware cost, and simplifies the steps of video acquisition, reducesthe distortion of the video and improves the accuracy of the restored video.

Description

technical field [0001] The present invention relates to the technical fields of wireless communication and computer, in particular to a video restoration method and device. Background technique [0002] With the wide application of 4G IP data transmission technology (Voice over Long Term Evolution, VoLTE), the demand for video calls through VoLTE is also increasing. Therefore, the quality test of video calls has also become the focus of attention. [0003] In the prior art, when testing the video quality, firstly, the video data of the sending end and the receiving end are obtained, and then the video data of the sending end and the receiving end are compared and analyzed frame by frame, so as to obtain the test result of the video quality. [0004] Among them, the following two methods are mainly used to obtain the video data of the receiving end: [0005] The first method is: use a high-definition camera to shoot video data at the receiving end, that is, place a high-defi...
