i am doing a project on VIDEO CONFERNCING using JMF. i am using the HP WEBCAM of my laptop. guys i desperately need help. plz give me the code if any of has it.plz plz its urgentYou can't get the code for the whole application.....
but you can get plenty of code to get started on making your own video conf. application using JMF here .
Also, there is a [JMF Forum|http://forums.sun.com/forum.jspa?forumID=28] here. If you face any problems while coding, you can post your queries there.
Thanks!

Does anybody have the source code for playing video..?

Hi i am new to J2ME. Does any body have the source code for playing video?

The WTK includes a video player example. I would start by looking there. In addtion SE and Nokia (if I remember correctly) both have video examples on their developer web sites.
The developer sites are
http://forum.nokia.com
http://developer.sonyericsson.com
For some of my midlets I use a utility class. You can view the source here:

Codes for audio video receiver class

I am currently writting an audio and video receiver for my project based on AVReceive3, it works but i can only get Video only, everything seems to be normal, i dont see why i am not getting audio. My transmitter is working fine and sending both streams.
If anyone can spot the error or mistake i a making, pleaase let me know as soon as possible.

I have to use RTP and RTSP for transferring the
audio/video streams in real time.
How I can sen and receive RTP packets.
How can I make the RTP Player.
What is the role of JMF in it.
Please suggest me and provide me the codes if
possible.
Thanks alot
shobhit vermaThere are two ways using which you can send and recieve packets using rtp. One without using the SessionManager and the other with.
1.) Not using the SessionManager makes things easy for you but it offers very little flexibility to you. You can do this by just specifying a medialocator pointing to the specific url
2.) Using the SessionManager is what is usually suggested. This process is more complex. First you have to instantiate a RTPSessionMgr to a SessionManager reference using which you can send and receive streams to and from the network. The process is more involved than this and is suggest you read some tutorials to get a better understanding, than me explaining to you the entire process.

Video Conferencing using java

hi,
i am developing video conferencing project using JMF.
and using AVReceive2 and AVTransmit2.
i am able to send and receive audio and video between two pc's where one transmits and one receives.
but how to use AVReceive2 and AVTransmit2 for more than two pc's when any one doesnot have information that other user is transmitting.
What i mean is that when one user wants to connect to another user then how can second (receiver) know that someone is sending him data.
Basically when to run the AVReceive2 program on second PC..

hello anyonebaris,
Am currently working wid this topic of audio video conferencing using java.....N i wud be glad if u wud try helping me out....
I wanted to find out the actual function the server performs while the audio video transmission is going on in a JMF based platform ...Am using java 1.5 ...n JMF 1.2.1...
Is the server monitoring the clients and how..??..what function is it performing while establishing the link between the two clients...??
.....................Plz try 2 help me out....

Risks when using DV camcorder for ichat video conferencing..

I have a sony dcr pc350. Bought it January of this year and havent had problems with it until recently. For some reason, the video head was damaged. When i play my DV tapes on it, thick gray horizontal lines appear, or sometimes it refuses to play the tapes completely. I just recently read one of the topics in the ichat AV FAQ and it mentioned that there's a risk that using a DV camcorder for ichat AV video conferencing can actually damage the camcorder. Now i'm wondering if that's the reason why my dv cam is damaged now. I haven't been using it to shoot some video footage for a while now, but i have been using it to video conference very often for about over a month now. And then recently, when i had to use it to shoot some video, that's when i saw that the camera needed repairs. As i've mentioned, I havent been using it for anything else (not even to shoot video) and i havent dropped it or anything. I pretty much take good care of it. So i'm thinking that it was my constant use of it for video conferencing that did the damage.
So my question is:
Has anyone else experienced some camcorder damage that might be related to frequent video conferencing use? If it does indeed damage the camcorder, what specifically does it do to it (what does it damage, how exactly does it cause the damage, etc...)? I'd like to know so I can be more specific when I bring it to the service shop for repairs.

Hello Albert,
I do NOT think that using your Sony with iChat AV poses any greater risk than using it for other things.
I used my Sonys (DCR-TRV17 and DCR-TRV70) for a while, but I switched to iSight before I damaged them. (I am clumsy.)
The kinds of damage I contemplated in the iSight vs Camcorder or other web-cam FAQ were:
- dropping or tipping the camera or the tripod upon which it was mounted,
- contamination from dirt, body oils, or dust, etc.,
- wear on the heads and internal moving components, and
- wear on the camera's electrical connections.
Moreover, regular professional clean and adjust is required for my Sonys based on usage hours. Such is NOT required for iSight.
Some of those risks can be mitigated by careful placement and use and by keeping the tape out when using the camera, but some risk always exists when using the equipment. My thought was that, if I wore out or damaged a camera by using it for hundreds of hours of video chat, I would rather wear out or damage iSight, which is cheaper than my Sonys were.
Please post back what your Sony Service Tech finds. I will be eager to read whether your camera needed more than a professional clean and adjust.

How to get source code for WinCE 6.0 USB Camera Driver for ARM4I Processor

Hi,
I am implementing USB camera driver for my mini2440 board which has an ARM4I processor. The sample code
"Windows Embedded CE 6.0 USB camera Driver" downloaded from:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=2ef087c0-a4ae-42cc-abd0-c466787c11f2
does not support ARM4I processors. When trying to generate in VS2005 Platform Builder my WinCE 6.0
image for mini2440 with the Third party catalog items "MJPEG Decompression Filter" and "USB CameraDriver",
the linker giver errors. Please advise where to find a working source code for USB (now revision 1.1
("full-speed") is supported in my WinCE 6.0 image) camera for my ARM4I processor. The code should
be in C# but C++ will be fine also.
Thanks,
   Paul

My problems with "Creating an Extended Web Dynpro Application" are to massive to be posted on this forum in this stage. What I want to have some help with is to find the source code for that tutorial so I can get som guidence from there.
Following text is cut out of this page:

Creating an Extended Web Dynpro Application
You can download the Web Dynpro project for the current tutorial from the Software Developer Network SDN (http://sdn.sap.com -> Web Application Server -> Web Dynpro -> Sample Applications and Tutorials) in two versions: one skeleton version you can use for exercises and one final version (solution) for an immediate build, deployment and run on the Java engine of the SAP Web Application Server.
How hard I try I can't find the specific source code on sdn.sap.com
Does anyone have a clue where it is?
Thanks!
Best regards

Hi!
I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
I am running a newer version of NWDS:
SAP NetWeaver Developer Studio
SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
Maybe that's why things don't look the same?

Need sample source code for calling stored procedure in Oracle

Hi.
I try to call stored procedure in oracle using JCA JDBC.
Anybody have sample source code for that ?
Regards, Arnold.

Thank you very much for a very quick reply. It worked, but I have an extended problem for which I would like to have a solution. Thank you very much in advance for your help. The problem is described below.
I have the Procedure defined as below in the SFCS1 package body
Procedure Company_Selection(O_Cursor IN OUT T_Cursor)
BEGIN
Open O_Cursor FOR
SELECT CompanyId, CompanyName
FROM Company
WHERE CompanyProvince IN ('AL','AK');
END Company_Selection;
In the Oracle Forms, I have a datablock based on the above stored procedure. When I execute the form and from the menu if I click on Execute Query the data block gets filled up with data (The datablock is configured to display 10 items as a tabular form).
At this point in time, I want to automate the process of displaying the data, hence I created a button and from there I want to call this stored procedure. So, in the button trigger I have the following statements
DECLARE
A SFCS1.T_Cursor;
BEGIN
SFCS1.Company_Selection(A);
go_Block ('Block36');
The cursor goes to the corresponding block, but does not display any data. Can you tell me how to get the data displayed. In the future versions, I'm planning to put variables in the WHERE clause.

Pc-to-pc audio/video conferencing

I've been looking into the ability of a direct (secure) connection from one Linux machine to another for the purposes of audio/video conferencing. I know there's stull like ekiga but that requires an account and a third party server. I'm looking for a solution that would be completely maintained between the two or three linux machines directly (webcam/mic). What's out there that I'm not seeing in google?

Also interested, been meaning to move away from Skype for a time now. I've looked/asked around and found opensips. You'll still need a client to manage calls though, I'll probably try out Twinkle. I'm going to spend some time trying to set it up myself. Hope it helps.
Edit Note: I quickly moved from twinkle to linphone.

Hi Team ,
I have find out the source code of the Package from dba_source at text column .
How can I find out
*1 .where the Database is mounted ie Server information and*
*2 .Name of the Sql file contains the package body*
*3 .location of the file in the Server*
Regards ,
AugustineHi - the source code isn't read in from a file by the database, it's actually stored in the database itself (have a look at the user_source view). Now you may have text files backups of your source code, that have been used previously to create the packages, but the database won't store any info about the file used to do this.

How do I see the source code for 'NI Example Finder'?

At the LabView Express demo, the rep showed us how to view the source code for 'NI Example Finder' (started with Help, Find Examples...). Please refresh my memory.
--todd

There are a couple of VI's that shipped with LabView 7.0, but you can't see the diagrams.
C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\Run Example Finder__NATIONAL INSTRUMENTS.vi
Press Ctrl-E on this VI and it prompts you for a password.
This VI is run by C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\HelpServer__NATIONAL INSTRUMENTS.vi
There's also C:\Program Files\National Instruments\LabVIEW 7.0\help\_exfinder.llb\Example Finder Launcher.vi.
Tyring to open this VI starts the NI Example Finder. Note the taskbar icon which is different from the normal VI icon.
It seems like NI is trying to keep us out, even if it used LabView to develop the Example Finder.
