Description
Technical field
The present invention relates to a kind of efficient regression testing methods based on audio and video encapsulated layer parameter detecting.
Background technology
The audio and video package type that present multimedia field is related to is more, for the encapsulation parsing module after edition upgrading
Test be required for covering a large amount of test materials every time, such as TS, FLV, MKV, AVI, MPG, MXF, MP4, WMV are per a kind of envelope
The test for filling format, is required for traversing the parameter that it is supported, more repetitive operation can all occur in each iteration, this
Sample is very big to the input of manpower, and is directed to a large amount of material and a large amount of parameter in each iterative process into pedestrian
The repeated authentication of work unavoidably will appear omission, result caused to be distorted.
Invention content
Based on this, it is necessary to provide a kind of automate and export result and can avoid one kind of other factors interference based on sound
The efficient regression testing method of video encapsulation layer parameter detection.
According to an aspect of the present invention, a kind of efficient regression test side based on audio and video encapsulated layer parameter detecting is provided
Method includes the following steps：
Conventional parameter and metadata in one media file are extracted using analytical tool, and by conventional parameter and metadata
It is written in a newly-built tag file A and preserves；
After analytical tool more new version, the new routine in the same media file is extracted by the analytical tool of new version
Parameter and new metadata, and new conventional parameter and new metadata are written in another newly-built tag file B and are preserved；
By comparing tag file A and tag file B, comparison result is exported.
The store method of tag file is as follows in one of the embodiments,：
By " | Start Code | packet length | Payload | " structure information storage in a manner of store the parsing of each media file
Each wide-angle data afterwards, wherein Start Code represent the start code of each structure information storage, and packet length represents
The length of Payload, Payload represent valid data.
Each wide-angle data corresponds to an audio stream after media file parsing or one in one of the embodiments,
Video flowing corresponds to for each wide-angle data that media file parses and generates a tag file.
The method for comparing tag file in one of the embodiments, specifically by the Start in two tag files
Tri- Code, packet length and Payload parts are compared respectively.
This efficient regression testing method based on audio and video encapsulated layer parameter detecting is parsed by each encapsulation
Audio and video conventional parameter and metadata are marked, and are synthesized according to the frame mode of each encapsulation itself, generate one
A new tag file that former media file characteristic value is marked, when each regression test, the solution with new version
The tag file that analysis tool needle generates the media file is compared to confirm whether update occurs rollback problem, this method
Automation output is realized as a result, a large amount of repeated works can be saved, the efficiency of test job is not only increased, also avoids other
The interference of factor.

Specific implementation mode
It to facilitate the understanding of the present invention, below will be with specific embodiment to invention is more fully described.But this
Invention can be realized in many different forms, however it is not limited to embodiment described herein.On the contrary, providing this embodiment
Purpose be to make the disclosure of the present invention more thorough and comprehensive.
A kind of efficient regression testing method based on audio and video encapsulated layer parameter detecting of one embodiment of the invention, including such as
Lower step：
Step 1, as shown in Figure 1, extracting conventional audio and video parameter and the first number in a media file using analytical tool
According to, and conventional audio and video parameter and metadata are written in a newly-built tag file A and are preserved.Specific to the present embodiment
In, then it is Video Parameter, the Audio that TS file video contents are extracted by the Parser modules of analytical tool
The information of Parameter and Element Stream three parts, and be written in a newly-built tag file, create tag file
Name it is consistent with the TS file names, preserved as test case；
Step 2, after analytical tool more new version, extracted in the same media file by the analytical tool of new version
New conventional parameter and new metadata, and new conventional parameter and new metadata are written in another newly-built tag file B and are protected
It deposits, principle is the same as step 1.
Step 3, as shown in Fig. 2, by compare tag file A and tag file B, export comparison result.Pass through upper one
As original record, the parameter information obtained with a collection of content with next version carries out the parameter information that a iteration version obtains
Regression test obtains final testing result.
Specifically, in the present embodiment, the store method of tag file is as follows：
As shown in figure 3, by " | Start Code | packet length | Payload | " self-defined information storage organization in a manner of store
Each wide-angle data after each TS document analysis, the starting that wherein Start Code represent each structure information storage are compiled
Code, packet length represent the length of Payload, and Payload represents valid data.
Each wide-angle data corresponds to an audio stream or a video flowing after media file parsing, for media file
Each the wide-angle data parsed, which correspond to, generates a tag file.Each for being directed to that each media file parses is wide
Angular data can all generate a corresponding tag file.As shown in figure 4, for the preserving type of each wide-angle data, when one
Media file has a video and an audio, then two tag files can be generated for this file, if corresponding matchmaker
Body file has multiple video flowings and audio stream, then can then be directed to each video flowing and the corresponding feature text of audio stream generation
Part, version is compared by these tag files before and after analytical tool, exports comparison result.
Specifically, in the present embodiment, the method for comparing tag file, as shown in figure 5, being specifically by two tag files
In Start Code, tri- parts of packet length and Payload are compared respectively.
For in various encapsulated layer regression tests, method through the embodiment of the present invention then only needs to prepare in first time
Upper some times of consumption can save the input of the module 80% test manpower in regression test from now on, pass through automation
Output result can quickly be found, and evade the rollback problem occurred because increasing new function rapidly.
This efficient regression testing method based on audio and video encapsulated layer parameter detecting is parsed by each encapsulation
Audio and video conventional parameter and metadata are marked, and are synthesized according to the frame mode of each encapsulation itself, generate one
A new tag file that former media file characteristic value is marked, when each regression test, the solution with new version
The tag file that analysis tool needle generates the media file is compared to confirm whether update occurs rollback problem, this method
Automation output is realized as a result, a large amount of repeated works can be saved, the efficiency of test job is not only increased, also avoids other
The interference of factor.
Above example only expresses the individual embodiments of the present invention, the description thereof is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
