Abstract
The invention provides it is a kind of based on RTMP without plug-in unit preview video method, comprise the following steps：Handshake data to RTMP is encrypted using AES；Service end obtains the data type of client request by interactive command；RTMP service ends are judged the type after Video coding, and are selectively accepted or rejected, and encapsulate audio, video data, are only sent and the related coding unit of broadcasting pictures to client.Beneficial effect of the present invention：Browser can be realized under different operating system without plug-in unit preview video, and the network bandwidth can be reduced, while reducing the workload of client decoding, and then reduce the broadcast time-delay of client；The encryption of the handshake data avoids the connection of illegitimate client, improves the security of service end.
Description
Technical field
The invention belongs to preview video technical field, more particularly, to it is a kind of based on RTMP without plug-in unit preview video side
Method.
Background technology
RTMP agreements (real time message protocol, real-time messages agreement) be by adobe companies formulate with
A kind of Streaming transfer protocol safeguarded, request is connected to service end and sends correct data to client since client,
This process is related to the shaking hands (simply shake hands, complexity is shaken hands) of RTMP, the encapsulation of command interaction, audio, video data.FLASH
PLAYER is currently the built-in module of many browsers, and itself also can be cross-platform with browser-cross, so adaptability is non-
Chang Qiang.The use of RTMP collocation FLASH PLAYER is to solve current video monitoring device and chrome browsers, safri browsers
Optimal case, compatible PC, android, ios system without plug-flow software, but is related to the security of service end and asks among these
Topic.
The content of the invention
In view of this, the present invention is directed to propose it is a kind of based on RTMP without plug-in unit preview video method, with different operating
Browser is realized under system without plug-in unit preview video, and avoids the connection of illegitimate client, improve the security of service end.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
Based on RTMP without plug-in unit preview video method, comprise the following steps：
A. the handshake data to RTMP is encrypted using AES；
B. service end obtains the data type of client request by interactive command；
C.RTMP service ends are judged the type after Video coding, and are selectively accepted or rejected, and encapsulate audio frequency and video
Data, only send and the related coding unit of broadcasting pictures to client.
Further, the handshake procedure in the step A is comprised the following steps：
A1. client sends C0, C1 data block, and server sends S0 and S1 after receiving C0 or C1；
A2. client sends C2 after collecting S0 and S1, and server sends S2 after collecting C0 and C1；
A3. after client and server receives S2 and C2 respectively, completion of shaking hands.
Further, the encryption method of handshake data is comprised the following steps in the step A：
A. the data S1 of server authentication client, the public key of generation is stored in the rear 4B of 1536B；
B. the data S2 of client validation server, the wherein generating process of S2 is：
B1. the genuineFMSKey that the KeyC1, KeyC1 and 68B of 32B are first found from C1 is generated by SHA256 algorithms
The pTempHash of 32B；
The pTempHash of the data and 32B that b2. take the preceding 1536B-32B in S2 generates the pLastHash of 32B,
PLastHash has been placed on the last 32B of S2.
It is of the present invention to be had the advantage that without plug-in unit preview video method based on RTMP relative to prior art：
(1) it is of the present invention can be realized under different operating system without plug-in unit preview video method based on RTMP it is clear
Device is look at without plug-in unit preview video, and the network bandwidth can be reduced, while reducing the workload of client decoding, and then reduced
The broadcast time-delay of client；The encryption of described handshake data avoids the connection of illegitimate client, improves the peace of service end
Quan Xing.
(2) RTMP agreements collocation FLASH PLAYER of the present invention are to solve current video monitoring device and chrome
The optimal case of browser, safri browsers, compatible PC, android, ios system, without plug-flow software, with other scheme phases
Than time delay is smaller, and user is more understood that and receives, and so as to reduce the operating procedure of user, improves Consumer's Experience.
Brief description of the drawings
The accompanying drawing for constituting a part of the invention is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate, for explaining the present invention, not constitute inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 be the embodiment of the present invention described in based on RTMP without plug-in unit preview video method flow diagram；
Fig. 2 is the schematic diagram of the handshake procedure described in the embodiment of the present invention.
Specific embodiment
It should be noted that in the case where not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Mutually combination.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, being comprised the following steps without plug-in unit preview video method based on RTMP：
A. the handshake data to RTMP is encrypted using AES, if client does not use AES, clothes
Business end can directly close the connection of client, it is to avoid the connection of illegitimate client, improve the security of service end；
B. service end obtains the data type of client request by interactive command；
C.RTMP service ends are judged the type after Video coding, and are selectively accepted or rejected, and encapsulate audio frequency and video
Data, audio, video data is encapsulated according to the official regulations of Adobe companies offer, is only sent and the related coding of broadcasting pictures
Unit reduces the broadcast time-delay of client to client, enables the client to timely playing video data.
As shown in Fig. 2 the handshake procedure in the step A is comprised the following steps：
A1. client sends C0, C1 data block, and server sends S0 and S1 after receiving C0 or C1；
A2. client sends C2 after collecting S0 and S1, and server sends S2 after collecting C0 and C1；
A3. after client and server receives S2 and C2 respectively, completion of shaking hands.
The encryption method of handshake data is comprised the following steps in the step A：
A. the data S1 of server authentication client, the public key of generation is stored in the rear 4B of 1536B；
B. the data S2 of client validation server, the wherein generating process of S2 is：
B1. the genuineFMSKey that the KeyC1, KeyC1 and 68B of 32B are first found from C1 is generated by SHA256 algorithms
The pTempHash of 32B；
The pTempHash of the data and 32B that b2. take the preceding 1536B-32B in S2 generates the pLastHash of 32B,
PLastHash has been placed on the last 32B of S2.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
