Online Video chat and communication are currently popular
However, using web videos is not that simple.
In the past, there were two ways to achieve one was to use the customer service Active Control and the other was to use the Java app, but both were not ideal.
One is that network signal collection cannot adapt to bandwidth, and the other is technical difficulties. Currently, the popular bchat is the first method, but I still cannot separate the control, I will not talk about the second method of selling free or commercial ready-made controls on the Internet, because Windows XP and above do not support Java.
However, the new Flash Communication Server MX Technology launched by Macromedia is easy to implement. For more information, visit the internet.
There are several existing examples after downloading the test version. Here we will talk about how to use aspx and flash to communicate with each other.
Send the finished image here.
This is a QQ-like online communication system written by Asp.net + SQL.
Functions are good. QQ functions are available here.
I was most proud to realize the video function.
The video function of Flash is in B-S-B mode, that is, there will be a zero-time video file in the service segment.
The specific code is packaged for download.

// Netconnection. onstatus (para) is used to monitor the information returned by the server.
// When the server returns information, this processor is triggered
// A parameter is an object that contains the returned information. It contains two fixed variables: Level and code. The parameter name can be named casually.
Client_nc.onstatus = function (Info ){
// Use the trace function to visualize the information returned by the server
Trace ("level:" + info. Level + newline + "Code:" + info. Code );

// Connect to the server and establish an rtmp connection
// The following is the relative address, because my web server and Flash Communication Server are on one machine.
// If your web server and Flash Communication Server are not on the same machine, the IP addresses of the two machines must be in the same domain.
// You can establish a connection and write it as client_nc.connect ("rtmp:/192.168.0.1/record_video ");
// Record_video is the name of the folder, which must exist in advance.
// Assume that you install the communication server by default, the record_video folder should be placed in

// Client_nc.uri is a required parameter pointing to the current rtmp connection.
// The third parameter is an optional parameter. True indicates that myvideo. FSO is written to the hard disk. False, null, or omitted means that no data is written and only temporarily exists.

// This processor is triggered whenever mongodobject changes
// The parameter is an array that records the changed content in mongodobject. Data.
// Each member of the array is an object, and the object has two members, code and name.
// Name indicates the changed content in mongodobject. Data.
// Code indicates the changes in the content, which is the information returned by the system.
// Connect the export dobject function to the server
