Recently in a BS-based video conferencing system, decided to use open source Fluorinefx.net and flex method to develop, early development is very smooth, including synchronous whiteboard. However, when the real-time video transmission, the original design is that each client can display three video, but to the test on IIS, the discovery State is very unstable, and occasionally can be fully displayed, in most cases, the client always randomly display one or two.

However, the data sent by the exact size of the buf.length error, so the two sides can stipulate that if the data sent is an integer multiple of buf.length, then add "#END" and then send, and the receiver received a separate #end will also indicate a read-in end.　1 classMynetstream2 {3 Public Const intMAX =5;4 NetworkStream stream;5 PublicMynetstrea

. Netstream class: when loading a video file that will be controlled by ActionScript, A netstream instance is used to represent the video content source. In this example, the video data stream is used. Using a netstream instance also involves the use of a netconnection object, which is a connection to a video file. It is like a channel for video data feed. Came

segmentation. Save the site traffic, that is, save server resources to improve load capacity. When the user opens a video, it is likely that the video will not be read, only part of it. If the video is not segmented, users can open the site to all the video data loaded, then the traffic is a huge waste. After segmenting the video we can load the video for a period of time so that the user will see how much we load. More flexible seek (drag), for a video that does not do any segment

code section of the main form, because we need to use network and network stream objects, we must first Add the following important Namespace ): Using System. Net; Using System. Net. Sockets; Using System. IO; Using System. Text; Next, add a NetworkStream object to our class to control the stream in the network. Private NetworkStream netStream; Add the following code to the constructor of this class to set the clock interval and make the program invi

Using actionscript3.0 scripts to play FLV videos requires collaboration of a series of classes:You need a netstream object to load videos and control video playback;However, the netstream class only processes flow data and does not process data display. Therefore, a video object needs to use netstream data to display videos on the screen.The

exist, the server will try again. In the end, if the email cannot be delivered, the email will be discarded or returned to the sender of the email. This concept is called end-to-end delivery, and it stores the mail in the queue until the mail is delivered. We can find the SMTP discussion from the two RFC. RFC822 describes the structure of the message, including the envelope. RFC821 specifies the protocol for controlling mail exchange between two machines. The following module uses the TcpClient

If you do not consider the security factor (anyone can connect FluorineFx for video recording without logon authentication), the server does not need to write a line of code, you only need to create a subdirectory under the apps directory as an application, and configure the rtmp Channel in the services-config.xml. The following as3 code of the flash client is modified from the official Flash AS2 example of FluorineFx (of course, there are many optimizations in the details) Package {import fl.

Rtmp's method of establishing a connection is already encapsulated, just call the ready-made interface function. But the disadvantage of using ActionScript to handle rtmp is also obvious-there are few places for yourself to develop. Since flash itself is n

server resources to improve load capacity. When a user opens a video, there is a good chance that the video will not be read and only part of it. If you do not segment the video, the user opens the site to all the video data loaded, then the flow is a great waste. After segmenting the video, we can load the video for a period of time, and we will load the user to see how much. More flexible seek (drag), for a video that does not make any segments, such as static video files on HTTP servers, we

Create three button components, named "play", "pause", and "stop" respectively, and drag and drop one of their instances to the scene stage. 2. Create a video component, drag an instance to the scene stage, and assign its insta
