Abstract
The invention provides a method for simulating an input video monitoring system of a multi-channel video coder. The method includes following steps: obtaining audio-video data, wherein the audio-video data are audio-video code streams obtained from coder equipment or directly-read local audio-video files; storing the obtained audio-video data in a buffering area, simultaneously setting an upper limit for the buffering area, and deleting the earliest data if exceeding the upper limit; and setting a sending buffering area corresponding to sending objects of each video monitoring system, sending the audio-video data stored in the buffering area to each sending buffering area, simultaneously setting an upper limit for the sending buffering areas, and deleting the earliest data if exceeding the upper limit. By the method, the input video monitoring system of the multi-channel coder can be simulated, so that investment cost for platform testing of the video monitoring system is substantially lowered, and testing period can be shortened.
Description
Technical field
The present invention relates to technical field of video monitoring, specifically, related to a kind of method of Multipexer video encoder input video supervisory control system.
Background technology
Video monitoring system generally comprises the component devices such as rig camera, DVR, The Cloud Terrace, The Cloud Terrace decoder.Make up a video monitoring system, most importantly exactly the performance of this system is tested, and the performance test of video monitoring system need to be simulated the video image on a lot of roads.In existing processing method, general actual encoder or IP video camera (the containing high definition) analog video image of adopting inputted, must need to drop into a large amount of equipment and build a such test environment, this will certainly strengthen the cost of investment and the cycle of test.And, for the analysis of video image content, need on-the-spot video recording data toward contact, and how these video recording data import in the video monitoring system as test sample book, also do not have the effective approach of a kind of ideal always.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby provide a kind of method of Multipexer video encoder input video supervisory control system, the method has solved the problem that need use a large amount of encoding devices when tradition is built the video monitoring system platform, has to be easy to realize the advantage low with cost of investment.
To achieve these goals, the technical solution adopted in the present invention is: a kind of method of Multipexer video encoder input video supervisory control system, and it may further comprise the steps:
Step 1: obtain audio, video data, described audio, video data is the audio-video code stream of obtaining from encoder device, or the local audio-video document that directly reads;
Step 2: the audio, video data that obtains is kept at buffering area, described buffering area capping simultaneously, the upper limit that surpasses described buffering area is then deleted data the earliest;
Step 3: the transmission object of corresponding each video monitoring system arranges the transmission buffering area, the audio, video data that is kept in the buffering area is sent to each transmission buffering area, described transmission buffering area capping simultaneously, the upper limit that surpasses described transmission buffering area is then deleted data the earliest.
Based on above-mentioned, described buffering area and described transmission buffering area all adopt the memory pool mode.
The relative prior art of the present invention has substantive distinguishing features and progress, specifically, support of the present invention is obtained code stream and reader ground file dual mode from encoder, can satisfy the multiple demand such as performance test, functional test demonstration, parser test of video monitoring system; The inventive method can Multipexer encoder input video supervisory control system, thereby decrease the cost of investment of video monitoring system platform test, can also shorten test period simultaneously.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
A kind of method of Multipexer video encoder input video supervisory control system, it may further comprise the steps:
Step 1: obtain audio, video data, described audio, video data can be the audio-video code stream of obtaining from real encoder, IP video camera, also can be the local audio-video document that directly reads;
Step 2: the audio, video data that obtains is kept at buffering area, and described buffering area capping if surpass the upper limit of described buffering area, is then deleted data the earliest;
Step 3: the transmission object of corresponding each video monitoring system arranges the transmission buffering area, the audio, video data that is kept in the buffering area is sent to each transmission buffering area, one tunnel audio-video code stream can be simulated the audio-video code stream input video supervisory control system up to the hundreds of road, when sending audio, video data, adopt multithreading, asynchronous transmission mechanism is then adopted in network service, thread traverses sends audio, video data after sending object, thereby the data that send between each object are independent of each other, and have guaranteed transmitting efficiency and accuracy; Described transmission buffering area capping if surpass the upper limit of described transmission buffering area, is then deleted data the earliest.
In order to improve the response performance of video monitoring system, described buffering area and described transmission buffering area all adopt the memory pool mode, and energy minimizing system is to frequent application and the release of internal memory like this.
Use the method after video monitoring system access audio-video code stream, can transmit the software of video monitoring system, the performance test such as storage; When the audio, video data that obtains is the local audio-video document that reads, can also reproduce on-the-spot real scene in live video actual scene mode, not only can be used for System Functional Test, client's demonstration, can also be used for the parser test of video image.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
