Can we implement multi party conference using jmf?

Hello every body
I want to implement the multyparty conference i finished the signalling part with SIP now i want to transmit the voice that conference. I have the receivers and trasmiters with me for individuals users but i need the multi casting part. How to multi cast the voice or vedio to the other partiipants of that conference once the conference server gets the voice or vedio. Kindly provide me the neccessary docs. If any sample code is there then well and good.
Thanking you in advane

Embedding the video or using streaming video doesn't necessarily change the total number of megabytes the end user has to download.
6-10 megabytes doesn't sound like a lot to me. I would be checking the actual available bandwidth at the other end to see if the issue might be there. Remember that many users don't actually have as much bandwidth as they think they have because they're actually sharing it with a lot of other people. And in places like India or China the time of day when you are trying to download can have a huge impact on the time it takes. When I was in Beijing a couple of years ago it was useless trying to download anything at certain hours of the day because of the load.
I don't believe Captivate creates any extra overhead. Whether SWF or HTML5 will be smaller is easy enough to find out. Just create a course in Cp6 and output it to both formats then measure the total filesize of each. That's a pretty good apples for apples test.

Can i create Multi Provider without using Cube

Hi,Can i create Multi Provider for ODS and Infoobject with using any Cube and
Can i create Multi Provider for Infoset and Infoobject.
Please give me the solution.
Thanks in Advance.
Regards

Hi,
In BW < 7.0, you can create multiproviders using:
- and/or InfoCubes
- and/or ODS
- and/or InfoSets
- and/or InfoObjects
You can also create InfoSets using:
- and/or ODS
- and/or InfoObjects
In BW 7.0, you can add the InfoCubes in the infosets.
Remind that the multiprovider is an union, the infoset is a join.

How can I implement Multi Factor authentication with IAM products?

Hi I would like to implement multi factor authentication that can be made generic with all IAM produts. Can anyone suggest an MFA factor like that? It shudnt be an add on or plug in. Instead it should be an in built feature. Can anyone suggest any idea?

Opensso has such feature built-in. You can create an authentication chain in which you can add as many authentication mechanisms as you need.
Although it is a built-in feature, there's no full support for all sorts of authentication methods. Some of them exist as plugins, like authentication modules for smart cards and biometrics because they are not sold by Sun Microsystems. However, there's a solution for you requrement even tough you might add some auth modules as plugins like biobex, activcard or auth modules from other vendors.

How can I implement multi page display

Hi,
I'm implementing a user interface which will display similar sets of data depending on the stage of the operation they are in.
I thought that the tabbed control would do where I could select the tab appropriate to the operation stage but I can't find a way of controlling the tab on display.
Is there a control that affectively display a page of controls depending on an inpute state/value.
Many Thanks
Andy
Solved!

When I placed a Tabbed Control on the front panel I doesn't give me tab control but tab output.
Right click the tab indicator and select change to control

I'm not familiar with propery nodes, can you point me to a tutorial on them.
To write a value to a control in the same VI, it is best to use a local variable. Property nodes are best used sparingly. Most of them alter the appearance of the widget on the user interface panel, and will cause an instant switch to the UI thread. This behaviour can be managed in LabVIEW 2011 (interesting discussion)

Some Benchmark checks
AndyNC wrote:
I have one remaining issue. The states that will control the tab control are text eg "Calibrate" and not numeric.
I can find a way of linking the states typedef to the tab control values.
If you create a typedef of the tab control, then all instances will have the same named pages. To add a page, alter the typedef custom control, and all instances will be updated. If you have LabVIEW 2011, a black triange will be added to the block diagram constants to show they are typedef controls.

Can you export multi track audio using FCPX?

hey guys
i can only find export audio under the "share" menu
and it has aiff,aac and mp3, no wav or omf and no options to include as multi tracks rather than a single stereo track or 5.1 surround
do you guys know of a way to export multiple tracks? without muting every track and export numerous times of course

Typed this hours ago and forgot to post it.....
Have actually done that and sent a test piece to the broadcaster. Not sure if I have got the audio tracks in the right order.... from top to bottom would that be audio tracks 1-4, with four at the bottom? I am waiting to hear back from the broadcaster to see if the test piece works as they expect it to.

How to implement multi threading without using Java's synchronization

I have a shared Object called "tradeObj" whose attributes are "Price" and "Quantity".
Thread1 is going to change the price and Thread2 is going to change the quantity but not stepping on each other's update.
Because of the cost of synchronization, I dont want to use "Synchronize", but still want to make sure both threads make their update in a proper manner.
Any ideas?

Use jmf implement RFC2833

i want to send dtmf tone with my sip soft phone according to RFC 2833.
but i don't kown how to modify some special rtp header(such as Marker header) when i use jmf to transmit rtp
and i have another problem, i have already transmitted the rtp, and then i click one number button,it should send another rtp, how shoud i do if i want two rtp to be a stream, i mean the two rtps have the continuous sequence number, not have its own increased sequence number

Hi,
I�ve implemented DTMF (RFC 2833) using JMF during my SIP soft phone development. To implement DTMF (RFC 2833) using JMF, you have to implement RTPConnector. You will find an implementation of RTPConnector, RTPSocketAdapter is built to support a custom transport mechanism under following URL:
[Transmitting and Receiving RTP over Custom Transport Layer|http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/RTPConnector.html]
I hope this information will help you!

IChat not allowing initiate of multi party video

iChat works for me in almost every case...even iChat to AIM...and even when the remote location is behind 2 NAT routers. It has worked between Tiger and Leopard, between Tiger and PC/AIMver5.9, and other scenarios. However, there is now a problem. I can video chat with user B (Tiger, iMacG5). I can video chat with user C (Leopard, iMac). I can make successful video calls to appleu3test01. I can even initiate multi party video chat with user C and appleu3test01. Typically, connections to user B come up at 1mbps (1000 kbps). I CANNOT initiate a multi party video chat with user B and appleu3test01. The problem is if I call user B first, my iChat will NOT let me add appleu3test01. However, if user B initiates the call, it works....but the video quality is not very good. One note, the video chats with user B typically come up a 400kbps. I have Quicktime set to "1.5mbps T1/LAN". I 've tried iChat set to 500kbps, 1mbps, and none. No other problems (so far) using video chat as initiator or receiver.

P.S.
In addition to my reply about the user B video settings and stacked icons...recall in the original post I noted that user B was able to initiate the multiparty video call just fine, and it worked. This would require him to have the "stacked camera icons", I think. In any case, he did show stacked icons when I initiated the video call, which connected to him just fine as the first participant, but then iChat would balk at my attempt to invite the next participant.
One thing that may be useful is that the message whe I tried to invite the last participant was that the participant was already in a chat...however the last participant's icon was showing as "available" for multiparty conference (ie; stacked icons). Maybe this indication was simply wrong and the last participant may have already been in a chat, especially since that participant was the "appleu3test01" user, which I imagine is very busy
If this is the case, it's just frustrating that iChat would show the user as fully available for multiparty video chat.

Problem with M-JPEG by using JMF and JPEGCodec .

Hi, there,
I want to implement a M-JPEG using JMF and JPEGCodec, is that possible?(I already been trapped)
My problem is I have a video clip which is a AVI file, the video format is following:
Video format: RGB, 160x120, FrameRate=14.9, Length=57600, 24-bit, Masks=3:2:1, P
ixelStride=3, LineStride=480, Flipped.
I already convered a frame to an Image object(video format with JPEG and CVID doesn't work) ,
I can also convert this Image back as a Buffer, It works fine with me .But to use JPEGCodec( provided by com.sun.image.codec.jpeg ) I need to convert an Image to a BufferedImage, I use the following defination:
BufferedImage bImage = new BufferedImage(frameImage.getWidth(null), frameImage.getHeigh(null),BufferedImage.TYPE_INT_RGB); It seems work, But when I use JPEGImageEncoder to encoder this bImage and save as a jpg file,
everything is black .
I also need to cast BufferedImage to an Image: frameImage = (Image) bImage; then I convert frameImage back to Buffer.My video clip still running , but every frame now became black .
can someone help me? thanks in advance.

I solved this problem . But I met a new problem.
I converted the above video clip into a JPEG and I want to create a DataSink for it. the messege is:
Video format: JPEG, 160x120, FrameRate=12.0, Length=3574
- set content descriptor to: AVI
- set track format to: JPEG
Cannot transcode any track to: JPEG
Cannot create the DataSink: javax.media.NoDataSinkException: Cannot find a DataS
ink for: com.sun.media.multiplexer.RawBufferMux$RawBufferDataSource@2b7eea
Transcoding failedHope some Java Experts can help me.

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO?

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO? It appears as if the Digital I/O modules for CompactRIO are much slower than this.
Thank you,
--Ray

Hi Ray,
The highest frequency input we offer for C Series modules is 20 MHz if you are doing LVTTL and 10 MHz for 5 V TTL. These modules are the 9402 and 9401, respectively. Unfortunately, there is no 80 MHz input on this form-factor.

Can we Implement YTD using MDX syntax in olap universe.

Hi,
I am trying to implement YTD prompt from universe level. Can any one suggest how can i implement it using MDX syntax in olap universe.
Regards,
Anil Kumar.

Hi,
In MDX, you need to generate the technical name to have you expression valid.
Moreover the correct syntax is: SUM(MTD(member),measure)
So in your case the prompt must be constrained on the technical name and cannot be free, the correct syntax is:
<EXPRESSION> SUM(MTD(@Prompt('YYYYMM','A','Cal. year / month\L01 Cal. year / month',mono,primary_key)),
@(Select(Key Figures\Total Variance)) </EXPRESSION>
Last, the result will be not really significant because you are asking for a MTD with a Year-Month as time member: the result will be the measure value for the selected month.
In your case you need to have a time series function for an upper level like YTD or QTD. If you want to use MTD, the the time member selected would be at a lowest level, such as week or day.

How can you stretch an image using JMF API

How is it possible to strech or zoom the video using JMF API? Streching may not distort the resolution, but, zooming might as I imagiine.

You can zoom with something like this:
public void zoomTo(float z) {
     if (visualComp != null) {
          insets = getInsets();
          Dimension d = visualComp.getPreferredSize();
          d.width = (int) (d.width * z);
          d.height = (int) (d.height * z);
          if (controlComp != null)
          d.height += controlComp.getPreferredSize().height;
          setSize(d.width + insets.left + insets.right,
               d.height + insets.top + insets.bottom);
}I suposse visualComp is the visualComponent of a player and this zoomTo(..) method is in a Component so you can call to setSize(..) method.
Of course the float z is the scale of zoom.
... i hope!
