Audio and video coding and transcoding problem quick checking method and system

Abstract

The invention discloses a method and system for rapid checking audio and video encoding and transcoding problems. The method includes the steps of reading data from a file or stream, conducting first process to obtain a first processing result, writing the first processing result to a designated storage path, conducting a second processing for the first processing result to obtain a second processing result, writing the second processing result to the designated storage path, conducting a third processing for the second processing result to obtain a third processing result, writing the third processing result to the designated storage path, and conducting a fourth processing for the third processing result to obtain a fourth processing result, and writing the fourth processing result to the designated storage path. During diagnosing the problems occurred in audio and video encoding and transcoding, comparing of data and internal state variables can be conducted frame by frame and data by data, so that problems can be positioned rapidly. The method is efficient and convenient.

Description

technical field [0001] The invention belongs to the field of video processing, in particular to a method and system for quickly checking audio and video encoding and transcoding problems. Background technique [0002] In the audio and video encoding and transcoding system, the common method of troubleshooting is generally to locate the problem through the on-site operation and maintenance personnel to capture the input and output signals and system operation logs, and further improve some modules to output more detailed information after the problem is located. Or take further experiments to locate the problem. As follows: [0003] read data from a file or stream; [0004] Decapsulate the read data, send the separated audio data to the audio decoder, and send the separated video data to the video decoder; [0005] The audio decoder decodes the received audio data into audio decoding data; [0006] The video decoder decodes the received video data into image data; [000...

AI Technical Summary

Problems solved by technology

[0012] In the above-mentioned normal video encoding activities, there are often 7x24 hours of uninterrupted encoding (such as live encoding of TV channels). When troubleshooting after a problem occurs, because the data from the file or stream often no longer exists, the troubleshooting is extremely difficult. Difficult, often can only be analyzed based on a large number of logs, and the changes of various data in the entire encoding and transcoding process have not been recorded, which often leads to only relying on log analysis to verify and find the final reason

The above methods often lead to too long problem solving time, it is necessary to introduce a further method to improve the efficiency of problem diagnosis
