Problems solved by technology
[0003] How to quickly locate the cause of audio and video file playback stuttering, the main technical means currently used by technicians in the technical field is to monitor the bottom buffer of the player in real time and obtain various abnormal information returned in the buffer step by step Carry out cause investigation, analysis and positioning. The use of such methods requires complete mastery of professional knowledge and skills in the field of player technology. Ordinary developers and testers cannot use such methods for analysis and positioning, thus limiting such methods At the same time, the analysis steps of this kind of method are cumbersome and the execution efficiency is low, which also hinders the rapid solution of the problem

Embodiment Construction
[0027] The following is attached figure 1 The implementation flow chart of the present invention is described in detail. The invention discloses a method for quickly locating the cause of audio and video file playback freeze phenomenon, and its specific implementation includes the following steps:
[0028] Start the video player of the device and play a video file saved in the local storage device. The name of the video file is "Test.ts":
[0029] Step 1: During the playback of the "Test.ts" file, extract and save the real-time bit rate information of the "Test.ts" file in real time, record the value as BR, and set the threshold value of the system CPU usage and memory Free thresholds, recorded as CPS and MFS respectively;
[0030] Step 2: During the playback of the "Test.ts" file, calculate the real-time reading rate of the "Test.ts" file read by the player in real time, and record it as DR;
[0031] Step 3, compare the two rate values obtained in step 1 and step 2, name...

The invention discloses a method for fast locating causes of unsmooth playing phenomena. The method includes the steps of firstly extracting and saving the real-time code rate value of an audio / video document in real time during playing of the audio / video document, and setting the threshold value of a system CPU occupancy rate and the threshold value of vacancy of an internal memory; during playing of the audio / video document, calculating the real-time reading rate of a player for reading the audio / video document in real time; judging various causes of unsmooth playing and prompting by continuously comparing the code rate value with the reading rate value, comparing the code rate value with a document reading rate value, comparing the CPU occupancy rate value with the threshold value of the CPU occupancy rate, comparing an internal memory vacancy value with the threshold valve of the vacancy of the internal memory and the like. By using the method for fast locating the causes of the unsmooth playing phenomena, developers can quickly obtain the fundamental causes of the unsmooth playing phenomena, and conduct a secondary analysis according to a prompted direction, so that the efficiency of solving the problem of the unsmooth playing phenomena in audio / video documents is greatly improved.
Description
technical field [0001] The invention relates to a method for locating the cause of playback freeze, in particular to a method for quickly locating the cause of playback freeze, and belongs to the technical field of multimedia playback. Background technique [0002] In recent years, with the rapid development of the mobile Internet, consumer electronics products have shown explosive growth, and the annual shipments of consumer electronics products have reached more than 100 million units. The audio and video content playback function is one of the core functions of consumer electronics products, and it is also one of the most frequently used functions by users in daily life. Therefore, the effect of audio and video content playback is directly related to the user's experience and evaluation of the product. How to improve the audio and video content? It has become one of the core requirements of consumer electronic products to improve the playback effect of content, thereby im...
