Video file quality detection system and method

Abstract

The invention discloses a video file quality detection system and method. The system comprises a Web interaction client which delivers a video quality detection task to a WebService managing server and displays a video quality detection state and detection result; the WebService managing server which sends the video quality detection task to a video quality detection server, reads the video quality detection state and detection result from a database and sends to the Web interaction client; and the video quality detection server which downloads to-be-detected video files from an Ftp video server, detects the video qualities of an ordinary video file and a video file containing HLS (Http Live Streaming) format according to file types and stores the video quality detection state and detection result in the database.In adoption of the video file quality detection system and method, the video quality detection of the ordinary video and the video quality detection of the video containing the HLS format are compatible; and the application range is wide.

Description

technical field [0001] The present invention relates to the field of computers, in particular to video processing, in particular to a video file quality detection system and method. Background technique [0002] Before a video program goes online, it is an important link to check the quality of the video source. This method is usually used for quality inspection of common video files (such as ts, mp4, avi, flv, mkv, rmvb, etc.): first decode the video file, and find out whether the video file has an encoding during the decoding process. Syntax errors, and then analyze the decoded audio and video data to find out whether there are defects such as black field, static frame, image blur, skipped frame, clipped frame, blurred screen, etc. in the video image data, and find out whether there is silence, Defects such as clipping and UV exceeding the standard, and finally evaluate and score the quality of the video file objectively according to the degree and duration of defects in ...

AI Technical Summary

Problems solved by technology

[0004] Because in the conventional film source quality detection method, only the quality detection of each ts video file is carried out, and the m3u8 file is not analyzed. However, the correctness of the m3u8 file is the most critical to whether the video file in HLS format can be played smoothly.

Moreover, separate video quality analysis for each ts video file cannot fully evaluate the quality of the entire continuous video stream, because the separate video quality detection for each fragmented ts video file will miss the possible existence of Defects such as frame skipping and clamping

Therefore, conventional video source quality detection methods cannot comprehensively and correctly detect and evaluate video files containing HLS format.
