Embodiment Construction

[0048]In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0049] Live streaming refers to live video streaming over the Internet. During the live broadcast, the terminal held by the host (hereinafter referred to as the host terminal) can shoot video, and the host terminal preprocesses the captured video and then encodes it, and sends the encoded stream to the server. The server transmits the code stream to the terminal held by the viewer after transcoding and other operations (hereinafter referred to as the viewer terminal). After the viewer terminal decodes the received code stream, it can be rendered and displayed on the scr...

Abstract

The invention relates to a live video quality evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: periodically cutting video frames from afirst live video according to a preset time interval; for each intercepted video frame, inputting a brightness component in the video frame into an image quality classification model to obtain a quality category of the video frame output by the image quality classification model, the image quality classification model being obtained by training according to a plurality of training samples, whereineach training sample comprises a brightness component and a quality category label of the sample distorted image, and each quality category label is obtained by performing quality evaluation according to the corresponding sample distorted image and a standard definition image corresponding to the sample distorted image; and reporting the quality category of the first live video to a server according to the quality category of each video frame. By adopting the method, the quality evaluation efficiency and accuracy of the audience terminal live video can be improved.

Description

technical field [0001] The present application relates to the field of Internet technologies, and in particular, to a quality evaluation method, apparatus, computer equipment and storage medium for live video. Background technique [0002] With the rapid development of the webcasting industry, more and more users meet their daily entertainment needs by watching webcasting. [0003] In the process of live webcasting, after the host terminal captures the video, it will preprocess and encode the video, upload the encoded stream to the server, and the server will then perform video transcoding and other operations on the encoded stream. Afterwards, it is delivered to the viewer's terminal as a live video for the user to watch. [0004] However, in the above-mentioned online live broadcast process, the live video received by the viewer terminal may be distorted, and how to quickly and accurately evaluate the quality of the live video received by the viewer terminal has become an...
