Problems solved by technology

[0030] There are certain obstacles in the decoding test, because the encoded code stream data is related and contains a lot of information. The existing technical solutions In the decoding test, the code stream is usually manually generated by the reference model, or the encoded code stream is downloaded from the Internet, and then the reference model is used to decode the code stream. The decoding test effect is not good, and the test result data is not very accurate

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0042] A kind of video decoding efficient test method, see figure 1 The three stages shown include compatibility test, performance test and error correction ability test;

[0043] The compatibility test adopts the equivalent division method: firstly, the video data to be tested is classified, and the encapsulation format of the file type is distinguished by the suffix name of the file, thereby obtaining different types of encapsulation files, and the different types of encapsulation files are passed through the PC on the PC. Auxiliary tool distinguishes the file of the different encoding types of the same encapsulation file, and described auxiliary tool comprises Media info analysis software, Kmplayer video player; With the file input video player of the different encoding types of encapsulation file and carries out playing output corr...

Abstract

The invention provides an efficient test method for video decoding, which is characterized by comprising three stages such as a compatibility test, a performance test and an error correcting capability test, wherein an equivalent divide method is adopted in the compatibility test: video data to be tested is classified, files of the different coding types in the same packaging files are input into a video player for playing and outputting files results corresponding to different coding types, and the results are compared; a boundary test method is adopted in the decoding performance test: the video data to be tested is collected, the collected video data is played through a video player so as to test whether the video data can be played, and is fluent and synchronous, performance assessment is carried out based on the output result; and the equivalent divide method is adopted in the error correcting capability test: the stability and error correcting capability of a player are assessed after ensuring the basic work of the video player. By the test method, the test of the video decoding is more comprehensive and convenient.

Description

【Technical field】 [0001] The invention relates to the field of multimedia, in particular to an efficient testing method for video decoding. 【Background technique】 [0002] 1.1 Video Definition [0003] Video generally refers to various technologies that capture, record, process, store, transmit, and reproduce a series of static images in the form of electrical signals; another way of saying that continuous image changes exceed 24 frames per second At the same time, according to the principle of persistence of vision, the human eye cannot distinguish a single static picture, which appears to be a smooth and continuous visual effect. Such a continuous picture is called a video, which usually refers to the storage format of various dynamic images. The mentioned here Video refers to compression techniques and file attributes for video data. [0004] A file usually consists of three parts, namely the file header, data block and index block. [0005] The file header includes pa...
