Abstract

The invention relates to a coding and decoding quality test method and device, computer equipment and a storage medium. The method comprises the following steps of: in response to a test request for a to-be-tested product, acquiring to-be-analyzed audio data and to-be-analyzed video data output by the to-be-tested product; performing frame extraction on the to-be-analyzed audio data and the to-be-analyzed video data to obtain at least one to-be-tested video frame with a timestamp and at least one to-be-tested audio frame with a timestamp; extracting a sample video frame having the same timestamp as the to-be-tested video frame from the sample data, and comparing the sample video frame with the to-be-tested video frame to obtain image similarity; extracting a sample audio frame having the same timestamp as the to-be-tested audio frame from the sample data, and comparing the sample audio frame with the to-be-tested audio frame to obtain audio similarity; and if the image similarity reaches an image similarity threshold and the audio similarity reaches a first audio similarity threshold, determining that the coding and decoding quality of the to-be-tested product is qualified. By adopting the coding and decoding quality test method, the coding and decoding quality testing efficiency can be improved.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular to a codec quality testing method, device, computer equipment and storage medium. Background technique [0002] In the traditional codec quality test, the codec quality (including encoding quality or decoding quality) of the product under test is judged by arranging personnel to watch the playback of the output signal of the product under test. However, during manual testing, each person can only test one product to be tested at a time, which is inefficient. Contents of the invention [0003] The present application provides a codec quality testing method, device, computer equipment and storage medium, which can improve the efficiency of codec quality testing. [0004] A codec quality testing method, said method comprising: [0005] In response to the test request for the product under test, obtain the audio data to be analyzed and the video data to be analyzed cor...
