Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] Such as figure 1 As shown, the RTMP-based plug-in-free preview video method includes the following steps:

[0027] A. The RTMP handshake data is encrypted using an encryption algorithm. If the client does not use an encryption algorithm, the server will directly close the connection of the client, avoiding the connection of illegal clients and improving the security of the server;

[0028] B. The server obtains the data type requested by the client through interactive commands;

[0029] C. The RTMP server judges the type of encoded video, and selectively chooses, encapsulates the audio and video data, and encapsulates the audio and video data according to the official specificat...

Abstract

The invention provides a plug-in-free video previewing method based on the RTMP (real time message protocol). The plug-in-free video previewing method comprises the following steps: handshake data of the RTMP is encrypted with an encryption algorithm; a server obtains data type requested by a client through an interaction instruction; an RTMP server judges the type of a coded video, performs selective acception and rejection, packages audio and video data and only sends a coding unit related with played pictures to the client. The plug-in-free video previewing method based on the RTMP has the beneficial effects that plug-in-free video previewing in a browser can be realized in different operating systems, network bandwidth can be reduced, client encoding workload is reduced, and playout delay of the client is reduced; connection of an illegal client is avoided by encrypting the handshake data, and the security of the server is improved.

Description

technical field [0001] The invention belongs to the technical field of preview video, in particular to an RTMP-based plug-in-free preview video method. Background technique [0002] RTMP protocol (real time message protocol, real-time message protocol) is a streaming media transmission protocol developed and maintained by adobe company. From the client to request connection to the server to send the correct data to the client, this process involves RTMP Handshake (simple handshake, complex handshake), command interaction, audio and video data encapsulation. FLASHPLAYER is currently a built-in module of many browsers, and it can also be cross-platform and cross-browser, so it is very adaptable. Using RTMP with FLASH PLAYER is the optimal solution for current video surveillance equipment and chrome browsers and safri browsers. It is compatible with PC, android, and ios systems, and does not require streaming software, but it involves server security issues. Contents of the ...
