How the client can send video data of it's camera out without using JMF?

The client A and B don't install the JMF software.How the client A can send video data of it's camera to another client B,when the client A and B login in a web server on which the JMF software has been installed?Off course,all of them have the JRE.
This is my a video exchang software in doing now using JMF technology.I hope every client using the video exchange function need not install the JMF software when the web server have installed the JMF software.

For playing back, may be it is possible to "jar" the jmf along with the application and the upload on the server, then it may recognize all the classes but there can still be problem because JMF depends on many ".dll" files which are stored in System folders, as I have seen. So,........This is correct, mostly. Here goes a captfoss inforant...
JMF is a collection of Java files (jmf.jar) that perform a certain set of functions, and it's also a set of native library files. You can use the Java JMF stuff with web-start, so the clients wouldn't have to have JMF installed to use the Java JMF stuff. The problem with doing this approach, you always have to ask yourself "Can I do what I want to do without the native library stuff?"
To answer this question, it's important to take a look at the JMF supported formats page.
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/formats.html]
If you look in the column "JMF 2.1.1 Cross Platform Version", it'll tell you what you can do in pure JMF, without any of the native libraries. In the case of capturing data, the only thing you can capture without native code is audio through the JavaSound system.
If you take a look at the RTP formats listed, you'll see a problem...the cross-platform version can't send any kind of video data to itself, which means you'd have to send MPEG1 to a transcoding server to bounce it back to the second client as a JPEG image...and that's if you somehow had the video data you want to transmit, which you cannot get from the cross-platform pack anyway.

Can I acquire data with VB from my DAQCard without using Measurment Studio?

I have the Measurement and Automation Software on my computer and VisualBasic.NET. Do I need any other software if I am receiving 2 analog signals and outputing 1 analog signal on my NI DAQCard-6024E PCMCIA?

The short answer is yes, you can acquire data with VB.NET from your DAQCard without using Measurement Studio.
There are a variety of ways to do it. All of them require that you install either the Traditional DAQ driver or the DAQmx driver in addition to Measurement and Automation Explorer. The DAQ drivers are included on a CD or CDs with your hardware. They are also available on the quarterly National Instruments Device Driver CD.
1) You can use the Measurement Studio DAQmx .NET API. This is far and away the easiest API to use to program DAQ cards in VB.NET and C#. This API is included in the DAQ installer and does not require you to purchase Measurement Studio. However, without Measurement Studio you do not get the benefit of the DAQ Assistant integrated into Visual Studio .NET. The DAQ Assistant, when integrated into Visual Studio .NET, allows you to graphically configure your DAQ tasks, generates the code you need to configure your tasks, and generates a .NET user control (with user interface) that demonstrates how you use the tasks that you created. The caveat to this approach is that PCMCIA cards are not directly supported under DAQmx 7.0. There is, however, a beta versin of DAQmx PCMCIA support as described in this KB article.
2) You can use the .NET P/Invoke services to call the Traditional DAQ or DAQmx C API directly. See MSDN for more information about P/Invoke. If you choose the DAQmx API, you will need to install the beta of the PCMCIA support as described in this KB article. National Instruments does not provide any examples, language-specific documentation, or code generation for this method. You'll need to look at the C API documentation to see what to do.
3) You can use the Measurement Studio Traditional DAQ ActiveX controls. These are included in the DAQ installer and do not require you to purchase Measurement Studio.
The absolute quickest and easiest way to get started using an NI-DAQ card in VB.NET is through the DAQ Assistant and Measurement Studio Professional or Enterprise edition.
Your next best approach is to use the native .NET DAQmx API. This API was designed from the ground up to support .NET languages. There are examples written in VB.NET to help you get started.
If for some reason, you don't want to use the native .NET API (or your hardware is not supported under DAQmx), whether you use P/Invoke or the ActiveX controls is a toss-up. It depends mostly on whether you are already familiar with the C API or the ActiveX API.

How do I upload my video from my camcorder to my MAC without using firewire?

My mac was purchase in 2009 and I have imovie '09 installed. It has a mini DVI port but no firewire port. Please tell me there is a way to get video from a camcorder to imovie? Right now I have a Sony DV camcorder but I'm willing to purchase a new camcorder that is compatible if necessary. Help!

If you want to use your DV camcorder you need firewire. If you have tapes that you would like to import to iMovie, your best bet is to find a friend with an iMac that will let you capture to an external hard disk. Once the movies are on a hard drive, you can use USB. You only need Firewire when capturing off tape. Another option would be to hire a service that will put your tapes on a hard drive. You can Goole for these.
If you would consider a new camera, get a camcorder that shoots AVCHD or h.264 or iFrame. These attach via USB. If you get a camcorder that uses an SDHC or SDXC card, you can import from a USB card reader.
You can find compatible camcorders here. http://help.apple.com/imovie/cameras/en/index.html?lang=en_US

How my clients can upload raw video files to my linux server

Any ideas or thoughts really welcome:
I need to figure out a way or process for my clients to upload their raw video source files ( any known usual video formats and extensions) from their video cameras or devices or storage source that is tied into or thru their computer with a firewire or USB 2+ connection    and then uploaded directly into my remote linux server.   my linux server hard drve space is not a problem..
Once client has finished uploading, I would then download the resulting saved files to my computer for video/audio editing using Premiere 11
I know that one restriction or problem would be their connection and ISP issues (throttling etc.) , My server permits basically unlimited up/download traffic, so this should not be a problem and server has balancing.
Do they need to use a typical ftp account and something like cuteftp???   however my understanding of FTP clients do not do streaming from a device???? yes or No??   I always thought just static files.....   aam I correct?
how might my clients stream into my server.   i am wanting to set up an online video/audio editing website
once i finish editing I would upload file probably as a zip file for them to unzip. I can also build and send (mail) out a DVD-CD or Blu-ray. any other thoughts welcome on returning the finished edit.
My tech people say that i cannot effectively load and operate Premiere onto my server to do the editing.
I would appreciate any feedback and ideas
thanks

How people upload files to your server is really a question for your server company... you need to find out from your server company how they handle permissions and uploads
Yes, no current version of Premiere Pro or Elements is written to EITHER install on, or directly use files resident on a server
No current version of Premiere works properly over a network
-you may NOT "map" your My Documents folder to a network drive
-you MUST give all users administrator accounts to use Premiere
-you MAY also need to... http://forums.adobe.com/thread/969395

Once you and your server company figure out permissions and the software your clients need to use for uploads, you will then need to download the files to your video data hard drive to edit

How many clients can associate to the AP?

Hi
I need know how many clients can associate for this AP model
AIR-CAP3502I-A-K9
AIR-LAP1131G-A-K9
I have 45 clients currently associated with each AP.
Thanks

I need know how many clients can associate for this AP model
Theoretically, you can have 1098 clients per WAP. However, in practice, this will depend entirely on the type of Wi-Fi traffic being pushed around.
Cisco recommends no more than 25 clients per WAP. But if you are just pushing emails, HTML around then this number can go as high as 35 clients per WAP. If you are pushing HD video, then the number goes down to around 8 clients per WAP.
I have 45 clients currently associated with each AP.
This is too much. Even for a 1131. Take note that, unlike the 3502, the 1131 only has FastEthernet data port. So with 45 clients connected to the 1131, you may have some bottleneck.

After connecting the clients to start video chat using RTMFP , Can the server finish the video chat between clients regardless of clients' will ?

Hi,
I looked on this site http://portforward.com/routers.htm
It lists many routing devices both modems and routers.
I did not see the Surfboard you listed but that does not mean it does not route (It just means it is not in the list)
Your computer is getting the IP 192.168.1.3 which means a device somewhere between you and the internet is routing.
Most likely in System Preferences > Network for the connection method you are using you can see a "Router IP" (192.168.1.1 is most likely based on the IP you get)
Type this into to your Web Browser like you would Apple.com
You should get a Pop Up.
Hopefully it will tell what device you are now trying to Log in to.
This info may help in looking in the Port Forward list.
If not check all the Motorola devices listed and then iChat in the Next page.
The third page from the Link page I gave you will detail the default access info (IP and User ID and Password) for each device you visit.
You may find that there is a common User ID and password across the various devices and this may work for you.
At Random this one says admin and motorola as the User ID and Password. (others may say different)
Don't worry about the fact it says to set a Static IP at this stage Or the Port Forwarding info further down each page.
You will hopefully be now looking at the web pages stored on the modem.
They work like any other web pages with menu items and links to other pages.
Search all the menu items and link to see if the device has UPnP
It tends to be in different places on different routing devices but try Advanced or Admin as well as anything to to do with opening ports.
A Status page like the first pic on the second link page I listed may well tell you if it has UPnP enable or not (but this is not always the case)
Tell us what you find out or if you have some other routing device in between you and the Motorola Surfboard.

Hi, dear Sirs!
I'd like to suggest this: as I installed in my apartment N° 4 Airport Extreme Units each one connected to Powered loudspeakers, why don't give the choice to send streaming data to all the units so it is possible to hear music trough each unit?
Thank you,

Dear tzbikowski
really many thanks for your prompt and right reply.
I didn't know it, but I found in iTunes popup, not only you can adjust the volume of each unit too!
But, I have another question, sorry:
This facility is on Safari Mountain Lion SW, but is it on iOS 6.01 or 5.1.1 as in my iPad ?

How many clients can connect to Topic?

I've just read through the jms tutorial and it seems to be ment to losely couple parts of a big systems. (delivery -> factory -> order)
I'm in the process of beginning a application which has the following structure:
One client sends a message to the server, the server sends this message to one or more clients. (in jms: sender sends message to topic, topic sends message to receiver).
Now the client which receive the message from the server isn't part of a system, it's actual a person who sits behind his/her computer and finds the messages interesting.
My question is about how many clients can "watch" the topic for messages? Are we talking about 50, 100, 500 or 1000 or maybe 10.000 ?

Jan,
I do not think that there is a forced limit for as long as your hardware can sustain.
It also probably depends from MQ vendor to vendor, and their JMS implementations.
In one of my apps 10,000 subscribers was the practical celing due to the memory limitations. (On Solaris 8, 2 GB shared memory)
In another that used open source JMS celing was much lower. due to its underlying EJB implementation (Linux).
I would suggest a clean box test. Benchmarking, stress and load testing you middleware is always a good idea. It will give you a good idea what your app can and can not do.

How my client can acces to my web Services??

We want buy Oracle9iAS and we want know How our clients can access aour web services? They need some special software? or just need to send us a XML?
Thanks

As long as they can send standard XML based SOAP messages, Oracle can handle it. Interoperability based on standards is critical for the team building Web services into the Oracle environment.
Backing that up, here is some pointers. Oracle belongs to both the Web Services Interoperability (WS-I) group (actually was a founding member along with IBM and Microsoft - http://www.ws-i.org) and SOAPBuilders (which is an ad-hoc consortium of several dozen vendors working on interoperability - http://ws-interop.oracle.com/soapbuilder/). One of our roles on the WS-I team is working on building a reference implementation of the WS-I Basic profile (specific versions of SOAP, WSDL and UDDI) which will be used to show interoperability amongst vendors in the WS-I.
If you download the developer preview of Oracle9iAS Containers for J2EE (see: http://otn.oracle.com/tech/java/oc4j/content.html) you will see it includes the SOAPBuilders interoperability test showing this so you can test it out yourself.
To see which standards groups Oracle belongs to, check out this page - in the Java space we participate in over 68 Java Specification Requests and more every day - but we also belong to W3C, OASIS and dozens of other standards groups and take that participation very seriously: http://otn.oracle.com/tech/xml/htdocs/standard.html
Finally, to see how your partners can test in an Oracle Web services environment independent of any special software, check out the latest demo put up a few days ago showing the built in tester that comes with any Web service published on Oracle9iAS - you get a Web page which lets you pass in parameters and try the Web service out on the fly. This tutorial happens to be publishing PL/SQL as a Web service but the same applies if you publish an EJB, JMS queue, or Java class as a Web service (see step 24):
http://otn.oracle.com/tech/webservices/htdocs/series/plsql/content.html
Hope this is a start for you.
Mike.

Is it possible for the client to receive constantly data over tcp without\n

Hi
I have a server that constantly outputs measuring data. I would like some help with the client application that receives data and directly outputs. Client application is just receiving without sending anything. I have tried
BufferedReader stdIn = new BufferedReader(
new InputStreamReader(System.in));
     String userInput;
     while ((userInput = stdIn.readLine()) != null) {
     out.println(userInput);
     System.out.println("echo: " + in.readLine());
But it hangs, because there is no end of line from server, how should I proceed to constantly retrieve data from server?

I tried with
InputStream is = new BufferedInputStream(CLSocket.getInputStream());
System.out.println("Connected");
is.read();
but my application hangs (is runing without stopp, looping forever) when it comes to is.read();
what should I do?

How the client to detect the server has closed the socket?

if the server closed the socket by an unnormal way, for example, closing the socket compulsively. Then the client will show the "IOException:java.net.SocketException: Connection reset" message,
how the client to avoid such an error message to the user/customer, I mean , what the client can deal with such a message?
where to put the dealing code?
try{ int receivedLength=in.read(receivedBytes);
}catch(SocketException e){
// put the code here? }
catch(IOException e){
}

Do you know how to prove it---"a socket read should
always always always have a timeout";As ejp said (IMHO ...) it's his opinion and doesn't need proof. I respect his opinion, but I often write code that doesn't set this.
Instead I use 2 threads per connection, and don't care if the read thread goes to sleep, since I can still write. If you only have one thread per connection, you better ensure that the read will end in a relatively short amount of time, even if your partner decides it's time to go for lunch.
how the length of this timeout will be? That is a business decision, it all depends on the expected time between received messages and is application dependent.
is it a field of the socket?If you are using blocking mode sockets you set this with setSoTimeout. If you are using non blocking mode NIO you specify it on the select call, although the soTimeout should also work there, although I've never tried that.

How many clients can be connected to an Access Point

Hi friend,
I want to know how many clients can be connected in Cisco AP 1140.
Best Regard,
Marco.

Hi,
As Stephen mention the best answer is it depends.
What you need to keep in mind is that wireless is halfduplex and a shared medium and due to this the bandwith will go down per client.
http://www.cisco.com/en/US/products/hw/wireless/ps430/products_qanda_item09186a008009483e.shtml
Q. How many clients can associate to the AP?
A. The AP has the physical capacity to handle 2048 MAC addresses, but, because the AP is a shared medium and acts as a wireless hub, the performance of each user decreases as the number of users increases on an individual AP. Ideally, not more than 24 clients can associate with the AP because the throughput of the AP is reduced with each client that associates to the AP.
