Flash中ExternalInterface.call返回null,无法调用JS

2009年5月27日 admin 1 条评论

今天郁闷啊,在网上找了半天都不知道是什么问题,最后终于找到了, 原来嵌入SWF文件的时候要有ID, 加入ID=”movie”就可以了.
真是郁闷,对了,还有一点,就是一定要设置allowScriptAccess=sameDomain

简单的Socket通信例子

2009年5月6日 admin 2 条评论

所谓socket通常也称作”套接字”，用于描述IP地址和端口，是一个通信链的句柄。应用程序通常通过”套接字”向网络发出请求或者应答网络请求。 Socket和ServerSocket类库位于java.net包中。ServerSocket用于服务器端，Socket是建立网络连接时使用的。在连接成功时，应用程序两端都会产生一个Socket实例，操作这个实例，完成所需的会话。对于一个网络连接来说，套接字是平等的，并没有差别，不因为在服务器端或在客户端而产生不同级别。不管是Socket还是ServerSocket它们的工作都是通过SocketImpl类及其子类完成的。

下面给出一个最简单的Socket通信的例子供初学者参考：

服务器端：ServerDemo.java

package com.lanber.socket;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class ServerDemo {

/**
* 注意：Socket的发送与接收是需要同步进行的，即客户端发送一条信息，服务器必需先接收这条信息，
* 而后才可以向客户端发送信息，否则将会有运行时出错。
* @param args
*/
public static void main(String[] args) {
ServerSocket ss = null;
try {
ss = new ServerSocket(8888);
//服务器接收到客户端的数据后，创建与此客户端对话的Socket
Socket socket = ss.accept();
//用于向客户端发送数据的输出流
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
//用于接收客户端发来的数据的输入流
DataInputStream dis = new DataInputStream(socket.getInputStream());
System.out.println(”服务器接收到客户端的连接请求：” + dis.readUTF());
//服务器向客户端发送连接成功确认信息
dos.writeUTF(”接受连接请求，连接成功!”);
//不需要继续使用此连接时，关闭连接
socket.close();
ss.close();
} catch (IOException e) {
e.printStackTrace();
}
}

}

客户端：ClientDemo.java

package com.lanber.socket;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientDemo {

/**
* @param args
*/
public static void main(String[] args) {
Socket socket = null;
try {
socket = new Socket(”localhost”,8888);
//获取输出流，用于客户端向服务器端发送数据
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
//获取输入流，用于接收服务器端发送来的数据
DataInputStream dis = new DataInputStream(socket.getInputStream());
//客户端向服务器端发送数据
dos.writeUTF(”我是客户端，请求连接!”);
//打印出从服务器端接收到的数据
System.out.println(dis.readUTF());
//不需要继续使用此连接时，记得关闭哦
socket.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

}

Red5 Media Server and Security

2009年5月6日 admin 1 条评论

收集国外文章,呵呵 Red5的文章很少啊. 大家珍惜
Here are the steps to configure SSL in existing Red5 application. This article is keeping in the mind you have basic knowledge of Red5 or you are aware of how Red5 applications are built.

Software required on machine where Red5 server is installed:-

1: Open SSL //Open source SSL libraries required for compiling Stunnel

2: Stunnel //Open source SSL wrapper software uses open SSL works both on
Windows and Linux.

3: gcc // The GNU C compiler (although it always bundled with Linux
Machine, but I did not find it. Necessary if you are compiling the
Open SSL and Stunnel from source. Not required if using RPM

Configuration needed on server machine:-

1:- Install the Open SSL (if windows use exe RPM or source for Linux machine can be downloaded from openssl website).

2:- Install Stunnel (if windows, use exe otherwise RPM or compilation from source is preferred, can be downloaded from stunnel website). Make sure that you already have compiled Open SSL in your machine before proceeding with the installation of Stunnel; otherwise it will fail to compile.

Under Linux the standard command to compile Stunnel from source are described below. For any update please always follow the installation instructions given their website.

machine# gzip -dc stunnel-VERSION.tar.gz tar -xvzf -
machine# cd stunnel-VERSION
machine# ./configure
machine# make
machine# make install

There are several configurations that differ based on your computer and environment. That can be read from the website itself.

3:- Running Stunnel (There are several ways/mode you can run the stunnel. Follow the FAQ available in their website to choose the best which matches your requirements).
To run stunnel, you always require a configuration file. The process of making sample configuration file (stunnel.conf) is described below.

The sample configuration file used was like this:

sample.conf

; Sample stunnel configuration file by Sunil Gupta 2007
; Some options used here may not be adequate for your particular configuration

; Certificate/key is needed in server mode and optional in client mode
; The default certificate is provided only for testing and should not
; be used in a production environment

cert = /etc/stunnel/stunnel.pem
;chroot = /var/run/stunnel/
pid = /stunnel.pid
key = /etc/stunnel/stunnel.pem

; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

; Workaround for Eudora bug
;options = DONT_INSERT_EMPTY_FRAGMENTS

; Authentication stuff
;verify = 2
; Don’t forget to c_rehash CApath
;CApath = certs
; It’s often easier to use CAfile
;CAfile = certs.pem
; Don’t forget to c_rehash CRLpath
;CRLpath = crls
; Alternatively you can use CRLfile
;CRLfile = crls.pem

; Some debugging stuff useful for troubleshooting
debug = 7
Output = /var/log/stunnel.log
foreground=yes
; Use it for client mode
; client = yes
; Service-level configuration

;[pop3s]
;accept = 995
;connect = 110

;[imaps]
;accept = 993
;connect = 143

;[ssmtp]
;accept = 465
;connect = 25

[rtmps - https]
TIMEOUTconnect=20
accept = 443
connect = 80
TIMEOUTclose = 20

; vim:ft=dosin

Finish

Note: – When you install Stunnel, you get a default sample file, which is not enough in most of the cases to run the flash application. The additions to configuration file I made are as follows.
Also the line having ; in the start denotes the commented portion in file.

cert = /etc/stunnel/stunnel.pem
key = /etc/stunnel/stunnel.pem

pem stands for ‘privacy enhanced mail’ used as a key format. The above two lines tells the location of pem files need to be generated. This will be configured by user. The above is the best location for Stunnel although you can change it to any desired location.

;Some performance tunings

socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

The above two lines are for better performance of Stunnel in our case.

; Workaround for Eudora bug
;options = DONT_INSERT_EMPTY_FRAGMENTS

The above line is a bug in a specific platform, since we are running it in Linux; we commented this line, although it could be needed in some case.

; Some debugging stuff useful for troubleshooting
debug = 7
Output = /var/log/stunnel.log
foreground=yes

The above lines are very important, Because Stunnel by default run in background mode. You will never be able to see if it is running. So better to put it in foreground, so that you can make sure that stunnel is running properly. Also the debug = 7 is very important since by default stunnel does not generate any log. You can direct him to generate log, so that you can debug your application by seeing all those log messages. The above mentioned log directory is default Linux directory where all system logs are generated.

; Use it for client mode
; client = yes

In the sample configuration file, you will always find this option un-commented leading to a different architecture, since we are running Stunnel in server mode not client mode, so we will comment this line.

[rtmps - https]
TIMEOUTconnect=20
accept = 443
connect = 80
TIMEOUTclose = 20

And the very last lines are mentioned above. In the sample configuration file, you will never find rtmps and it is not even mentioned anywhere in Stunnel. The default file contains only https, add rtmps like it is added here. Also accept port is 443, which is the default port used for secure communication and it is open like port 80 in all corporate firewalls in general. This port is to accept the connection from flash and to get the encrypted data. The connect port is 80; this is the port where stunnel will forward the decrypted data to red5 server.
The TIMEOUTconnect and TIMEOUTclose can be useful in some cases when the server where the data is being forwarded by Stunnel is delaying the connection. This is to make sure that connection is closed only when server is not responding at all. The value is in seconds (i.e. 20 sec.)

Now in order to run your application under secure connection, you require a certificate to be created on the machine where the Stunnel is installed. The procedure for creating a certificate and the possible directory to put this certificate is described below.

Use of certificate:-

When an SSL client connects to an SSL server, the server presents a certificate, essentially an electronic piece of proof that machine is who it claims to be. This certificate is signed by a ‘Certificate Authority’ (hereafter a CA) — usually a trusted third party like Verisign. A client will accept this certificate only if
The certificate presented matches the private key being used by the remote end.
The certificate has been signed correctly by the CA. The client recognizes the CA as trusted.

Every stunnel server has a private key. This is contained in the pem file which stunnel uses to initialize its identity. If we notice above, we have given the reference of this pem file in the start of our configuration file under cert.

This private key is put in /usr/local/ssl/certs/stunnel.pem.

Note:-Under client mode we need not to have certificate in most of the cases, but if we are running it in server mode, we require a certificate. Since we are using server mode, I have generated a self certificate.

To make certificate:-

1: Go to /etc/stunnel directory and
2: Run the following command:-’

openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem

This creates a private key and self-signed certificate. More information on the options of this can be read from FAQ section of Stunnel website.

While executing the command, it will ask for some questions like Country, City, Company etc., Give the answer of those and it will generate the key and self certificate.

4:- Put your sample.conf file in /etc/stunnel directory where the .pem file was created earlier.

5:- Start Stunnel by issuing the command -

machine# stunnel stunnel.conf

If you are /etc/stunnel directory otherwise complete path of configuration file-

machine# stunnel /etc/stunnel/stunnel.conf

The above command will start the stunnel and you can verify the log from /var/logs/stunnel.log file.

Red5 server side changes:-

6:- Now stunnel is up and running, we need to change the Red5 configuration to accept the connection from Stunnel.

Go to red5 installation directory and search for conf folder where all red5 configuration files exist.

Open red5.properties file and under rtmps.host_port property put 443. The sample file can be like below.

rtmp.host_port = 0.0.0.0:1935
rtmp.threadcount = 4
debug_proxy.host_port = 0.0.0.0:1936
proxy_forward.host_port = 127.0.0.1:1935
rtmps.host_port = 127.0.0.1:443
http.host=0.0.0.0
http.port=5080
rtmpt.host=0.0.0.0
rtmpt.port=80

Flash client side changes:-

7:-Now we are done with server side, In order to run application under SSL, we need to change the client side protocol from rtmp to rtmps like below. And compile the flash client and run it on browser, a certificate will pop up, accept it and the application will run under SSL.

nc.connect (”rtmps://yourip/applicationname”); //used rtmps in place of rtmp

How to record RTMP flash video streams using Red5(使用Red5录制视频)

2009年5月3日 admin 没有评论

Red5 is an open source Flash server written in Java. It does not include a standalone client yet but I was able to write a Java program that uses Red5 to connect to an RTMP video stream and record / save it to a file. Code is provided below and also some tips on how to get the details required to download flash videos that you come across on the internet.

Here’s the code of “MyRtmpClient.java”, you are free to use and modify this in any way you want.

}

To compile and run the code you need the following libraries:

commons-collections-3.2.jar
jcl104-over-slf4j-1.4.3.jar
logback-classic-0.9.8.jar
logback-core-0.9.8.jar
mina-core-1.1.6.jar
red5.jar
slf4j-api-1.4.3.jar
spring-beans-2.0.8.jar
spring-context-2.0.8.jar
spring-core-2.0.8.jar

We need the latest Red5 JAR built from version control (not the latest official release) and I have uploaded these files here: red5-rtmp-client-libszip.pdf – just rename the file to end with “.zip” after downloading.

The code shown is hard-coded to connect to “localhost”, app name “oflaDemo” and stream name “IronMan.flv” which can be tested on the official Red5 server distribution which you can download and run. When it comes to downloading flash streams from the internet, WireShark can be used to sniff out the values you need.

Let’s take this site for example: http://videolectures.net/ Start a WireShark capture session before clicking on a video on the site to play it. Let WireShark grab all the information exchanged between your PC and the remote flash server and you can stop the capture once the video begins to play, we are only interested in what goes on during the connection handshake. I will use this video as an example: http://videolectures.net/ff06_chomsky_szmp/ [update Jun-2008: looks like they changed this particular video to Windows media instead of Flash, so try other videos or other sites]

In WireShark you can filter for protocol “rtmpt” and the first few entries would be handshake or “invoke” operations. Examining the “Handshake part 3″ we can easily get the value of the required “app” property. Below we can see it is “video/2006/other/ff06/chomsky_noam”:

For the host name, the IP address should do fine for most sites, but we can easily figure out the host name of the stream server from what appears after “rtmp://”. Note that WireShark allows you to search the text contents of captured packets. Here below we can see that the host name is “velblod.videolectures.net”:

And finally when the “play” command is issued – we need the value of the stream name. Below we see it is “chomsky_noam_01″:

So with the right values of hostname, app and stream name set – you can run the program and download the stream to your local drive for offline viewing. To download the whole stream – just change the duration to ‘-2′ as hinted in the source code comment. There are many free Flash players available you can use to play downloaded content such as FLV Player.

Do let me know if this works for you and if you find any additional parameters that need to be passed for other sites.

No buffer space available 解决方法

在网上找了很多文章,都没解决问题,以下文章来者国外的网站,终于解决问题了 ^_^

提示: 要把诺顿杀毒软件卸载

Editting the registry is not for beginners, if you don’t know what you’re doing I suggest you don’t try this, basically it’s use at your own risk.

Anytime you want to edit the registry it is a good idea to back it up first. For information on how to backup and restore the registry in all versions of Windows click here.

If you are using Windows 95/98/Me follow these steps:

First step is to launch the registry editor. To do this go to Start, Run and type regedit. In the left pane navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP once there, look for an entry called MaxConnections. If it exists highlight it by clicking it and then right click it and select modify. Increase the value (recommended value is to double the current value).

If the MaxConnections entry does not exist you must create it. To do this, right click in the right pane and choose new from the menu and select String Value. Give it the name MaxConnections. Then right click it and select modify and enter a value of 200.

Restart your computer, if all goes well then you fixed the problem, if not, revert the changes by restoring the registry. (You may have to reboot to safe mode to do this).

If you are running Windows NT/2000/XP follow these steps: First step is to launch the registry editor. To do this go to Start, Run and type regedit. In the left pane navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters once there, you must create the entry TcpNumConnections. To do this, right click in the right pane and choose new from the menu and select DWORD Value. Give it the name TcpNumConnections. Then right click it and select modify and enter a value of 200.

Restart your computer, if all goes well then you fixed the problem, if not, revert the changes by restoring the registry. (You may have to reboot to safe mode to do this).
