Description
Technical field
The invention belongs to technical field of video monitoring, and in particular to a kind of video big data cloud platform streaming media service side
Method.
Background technique
Raising with society to demand for security, video monitoring are that every profession and trade key sector or important place are supervised in real time
The physical basis of control, administrative department can obtain valid data, image or acoustic information by it, to the mistake of paroxysmal abnormality event
Cheng Jinhang timely monitors and remembers, to provide efficiently, in time commander and height, arrangement police strength, settle a case.
Streaming media service is mainly responsible for the access of monitor camera audio/video flow, and provides forwarding media stream, distribution service,
Realize the connection of video big data cloud platform front end applications and rear end video camera.
Summary of the invention
In view of the technical problem present on, the present invention is for providing a kind of video big data cloud platform streaming media service side
Method.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of video big data cloud platform stream media service method, comprising the following steps:
Streaming media service includes that Streaming Media mould shunts distribution module STDU and stream media scheduling module SS, is responsible for receiving front-end
The code stream of equipment PU is transmitted to client unit CU, and supports distributed deployment；
Stream media scheduling module is singleton service, is responsible for the STDU of management distributed deployment, and manages the stream of all distributions
State, and be recorded in redis, wherein STDU is used for multiple instances deployment, supports privately owned code stream, the input of third party's code stream, defeated
Out；
Request takes stream order C_SCHEDULER_StartStream, carries the PUID of needs, and returning response (IP,
Port, Token), call the library data transmission channel DTC to realize that client takes stream.
Preferably, client take stream detailed process is as follows:
Client initiation takes stream to request；
User's access service UAS forwards a request to Stdu_Scheduler dispatch service, Stdu_Scheduler according to
It loads discourse on politics selection and connects least STDU, STDU service generates tocken according to solicited message inside and returns to information
Stdu_Scheduler；
Link information and tocken are returned to user's access service UAS to information one by Stdu_Scheduler, finally
Client is returned to, another returns to equipment access service, equipment access service and PU interaction, takes by equipment access service
Band tocken information is sent to STDU；
Client establishes DTC with STDU with tocken information according to the link information of return and connects progress tocken verifying,
Receive code stream.
Using the present invention with following the utility model has the advantages that multilevel flow media cascade implementation, realization monitor camera view
Single channel access, the distribution of super multichannel of frequency, and support the elastic shrinkage of system, extension to meet under various emergency cases and video is supervised
Control the resilient expansion of system video distribution capability.
Detailed description of the invention
Fig. 1 is the realization process flow signal of the video big data cloud platform stream media service method of the embodiment of the present invention
Figure.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
In order to enable term involved in the embodiment of the present invention is more clear, it is right before to the description of embodiment implementation process
Technical term is illustrated.Streaming media distribution module (Stream Transfer&Dispatch Unit, STDU)；Flow matchmaker
Body scheduler module (STDU Scheudler, abbreviation SS)；Token: input/output stream unit；The administrative unit of Cell:Token,
Cell can be divided into PP, DP, CC three classes；Wherein PP is PingPong, is responsible for the one-to-one forwarding of Media Stream；DP is Dispatch,
It is responsible for one-to-one or one-to-many；CC is Cascade, is responsible for cascading between two STDU；SO:Stream Out, stream output
Module is responsible for distribution third party's code stream, has RTMP, RTSP, HLS, be all loaded into STDU with plug-in mode.
The invention discloses a kind of video big data cloud platform stream media service methods, which is characterized in that including following step
It is rapid:
Streaming media service includes that Streaming Media mould shunts distribution module STDU and stream media scheduling module SS, is responsible for receiving front-end
The code stream of equipment PU is transmitted to client unit CU, and supports distributed deployment；
Stream media scheduling module is singleton service, is responsible for the STDU of management distributed deployment, and manages the stream of all distributions
State, and be recorded in redis, wherein STDU is used for multiple instances deployment, supports privately owned code stream, the input of third party's code stream, defeated
Out；
Request takes stream order C_SCHEDULER_StartStream, carries the PUID of needs, and returning response (IP,
Port, Token), call the library data transmission channel DTC to realize that client takes stream.
In specific application example, referring to Fig. 1, client takes stream, and detailed process is as follows:
Client initiation takes stream to request；
User's access service UAS forwards a request to Stdu_Scheduler dispatch service, Stdu_Scheduler according to
It loads discourse on politics selection and connects least STDU, STDU service generates tocken according to solicited message inside and returns to information
Stdu_Scheduler；
Link information and tocken are returned to user's access service UAS to information one by Stdu_Scheduler, finally
Client is returned to, another returns to equipment access service, equipment access service and PU interaction, takes by equipment access service
Band tocken information is sent to STDU；
Client establishes DTC with STDU with tocken information according to the link information of return and connects progress tocken verifying,
Receive code stream.
The video big data cloud platform stream media service method realized by the above process can be used for the cascade of multilevel flow media
It realizes, realizes single channel access, the distribution of super multichannel of monitor camera video, and the elastic shrinkage of system, extension is supported to meet
To the resilient expansion of video monitoring system video distribution ability under various emergency cases.
It should be appreciated that exemplary embodiment as described herein is illustrative and be not restrictive.Although being retouched in conjunction with attached drawing
One or more embodiments of the invention is stated, it should be understood by one skilled in the art that not departing from through appended right
In the case where the spirit and scope of the present invention defined by it is required that, the change of various forms and details can be made.
