NewReceiveStreamEvent exception
Hello everybody
I'm unable to create DataSink, but the the datasource(ds) and dest(medialocator) is perfectly creating.
The below code is been used
stream = ((NewReceiveStreamEvent)evt).getReceiveStream();
DataSource ds = stream.getDataSource();
MediaLocator dest = new MediaLocator("file://e:/abc/rtp/test/temp.wav");
DataSink filewriter = null;
filewriter = Manager.createDataSink(ds,dest);
filewriter.open();
its giving the datasink exception
thanks in advance
insert "filewirter.start()"
you should wirte the content about the exception

i am creating rtp mixer .
for that i have made a program which receive rtp stream and then transmit it .
The problem with this code is that it first create receiver(it is a player) from the received rtp stream but receiver is stopped when treansmitter
(it is a processor) is created.
Earlier i was creaing the playe and processor from the same dataSourc so i thought it was creating problem . so i created transmitter (processor)
from the cloned dataSource . but the problem reamain as it was
what is the reason for this.
please help me because i am already late in this project .
very very thank u.
my code is :

JMF How to stream rtp from udp packet
I implemented an rtsp client and use the client to setup two rtp session(audio, vedio). But when I use the example pramgram "AVReceive3" to stream the udp packet, it doesn't work.
When the AVReceive3 receive the udp packet from the rtp port, it will call the update(ReceiveStreamEvent evt) function, and the event type is StreamMappedEvent, and the call to evt.getReceiveStream().getDataSource() return null.
I thought the first event should be NewReceiveStreamEvent. Please help to solve the problem.
What's rtp packet will cause the event StreamMappedEvent.

Thanks.The error of No format has been registered for RTP Payload type 96
is caused by the dynamic payload mapping, when I add the dynamic mapping between dynamic payload and format. The Player cann't work yet. I think it because JMF doesn't support the format of my clips. For example:
video: a=rtpmap:96 H263-2000/90000
audio:a=rtpmap:97 MP4A-LATM/12000/1
Is there some available plugin to support these format?
Thanks -
hi friends:
I am been looking into AVTransmit2.java, AVReceive2.java and AVTransmit3, AVReceive3
can your tell me what is the input and output of this function
where can I change to transmit and receive my DataSource
and Then presenting them

AVReceiver2 only received two ReceiveStreamEvents
Hi, I am new to JMF. I tailed the AVReceiver2 but it can only receive two ReceiveStreamEvents, one is NewReceiveStreamEvent and the other, StreamMappedEvent as I ran and traced the code. Below is the code.
JMF gurus, thanks in advance for your help.

return;I changed the code with threading model and RTPConnectionAdapter as below. almost same as avReceiver2 or avReceiver3. Once the code starts, it is in the a while-loop, sleeping, then printing a log. So, I can know the thread is alive and wait for any new streamEvent from update(), I hope. Unfortuantely, from the log of RTPConnectionAdaptor, the UDP socket kept receiving datagram packets from the network(I confirmed from SockInputStream.read() and SockInputStream.run()), but the Receiver thread still only received two ReceiverStreamEvents. It is very frustrated. Could anyone explain what is going wrong in the code? Thanks in advance,

Connecting view button to player! help
hi! I have posted my codes for Client and ClientChoice.
in the actionlistener event of the ClientChoice(gui) have i have called the Client class where the player is found and where connection is made to the server. the error i get is that the .class of the Client is:
mainCl(java.lang.String[]) in Client cannot be applied to (java.lang.String,java.lang.String) cl.mainCl(a,b);

Do any one kown how to encoder pcm to alaw if you use jmf?
I'm have the problem about it how to encoder pcm to alaw?
I find some code about it, but not work in jmf.
A friend in forum tell me write it by myself , because jmf not support for alaw.
But i'm new about this, so i want whether somebody could help me if you have the same code about this.

Big problem with put the same received dataSource on two different panels
Hello All!
I have a big problem, but first what have I done:
I am writting application that is based on AVReceiver2 and AVTransmit2 from Sun help.
I have modified AVReceiver2 to only receive one stream - video stream.
I show received video on scrollPane, but I want to show the same video on second scrollPane in the same time. I have read about cloning dataSource, but I don't know how to modify that code to make it work.
This is my receiver class (logger is my own class that have listbox, so don't watch on it. This is not important):

}I wanted to show the same video stream on 2 panels at the same time. The panels are on 2 different Tabs of TabbedPane.
So I done some kind of switch:
- when user change tab, I change vievport from one panel to another. This works gr8, but I need to record some received video on the same time when user watch it.
I find some code to record - this works on single machine, but now, when I have cloned dataSource I supposed to be able to record received video, but guess what: it doesn't work.

// Setup data source

any idea? -
Write(Export) the RTP Stream from a SIP Call to an audio file
I am working on telephony system that need record each call to a file.
I got the RTP Stream in ReceiveStreamEvent handler and start to record
the problem is i got a file and play it but there are any sounds
when i set FileTypeDescriptor.WAVE and AudioFormat.ULAW
I try out the FileTypeDescriptor.WAVE and AudioFormat.IMA4_MS, i got a fixed size file with 60kb
if the FileTypeDescriptor.MPEG_AUDIO and AudioFormat.MPEG, the processor cannot be realize,
the thread is blocked!!
Could anyone save me? thanks in advanced!

Attempting to write RTP stream to wave
I have been working long and hard trying to figure out to save an RTP stream from a Cisco phone to a wave. I need the wave file to be in the format ULAW, 8khz, 8 bit mono.
Through much research this is the code I come up with but I does not work. I states that I am trying to get a datasink for null when I try to create the filewriter datasink.
I also have gotten the following error message with other version of the code below:
newReceiveStreamEvent exception Cannot find a DataSink for: com.sun.media.protocol.rtp.DataSource@3680c1
When I get the RTP stream I get the following as the format of the input stream:
- Recevied new RTP stream: ULAW/rtp, 8000.0 Hz, 8-bit, Mono
else if (evt instanceof NewReceiveStreamEvent) {
try {
stream = ((NewReceiveStreamEvent)evt).getReceiveStream();
Format formats[] = new Format[1];
formats[0] = new AudioFormat(AudioFormat.LINEAR,8000,8,1);
FileTypeDescriptor outputType = new FileTypeDescriptor(FileTypeDescriptor.WAVE);
DataSource ds = stream.getDataSource();
// Find out the formats.
RTPControl ctl = (RTPControl)ds.getControl("javax.media.rtp.RTPControl");
if (ctl != null){
System.err.println(" - Recevied new RTP stream: " + ctl.getFormat());
} else
System.err.println(" - Recevied new RTP stream");
if (participant == null)
System.err.println(" The sender of this stream had yet to be identified.");
else {
System.err.println(" The stream comes from: " + participant.getCNAME());
ProcessorModel processorModel = new ProcessorModel(ds, formats, null);
Processor processor = Manager.createRealizedProcessor(processorModel);
processor.setContentDescriptor(new ContentDescriptor(ContentDescriptor.RAW_RTP));
MediaLocator f = new MediaLocator("file:/C:/output.wav");
DataSink filewriter = null;
DataSource tempds = processor.getDataOutput();
filewriter = Manager.createDataSink(tempds, f);
filewriter.open();

Edited by: phodat on Sep 16, 2010 10:20 PMThe content descriptor is designed to specify the output format, not the input format. The input format is specified by the DataSource automatically, and you set the content descriptor to whatever you want the output format to be. In this case, you'd want to set it to a WAV file.
You'd then need to go through all of the Track objects on the processor and set their output format to the ULAW specifications as you want there.

There's actually an example program that exports RTP streams, you can probably use that code without modification to fit your needs. -
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.

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.

Transmit and receive from the same ip address?
Helpers:
We 've been using transmit/Receive for a while, I read all the discussions. No one seem really know does the transmit send to a destination IP address and the destination receive from the same IP or the IP address the sender send from?
like sender send from: java Transmitter 123.4.3.162 5000
receiver receive from: java Receive 123.4.3.162 5000
or sender send from: java Transmitter 123.4.3.162 5000
receiver receive from: java Receive 10.118.5.162 5000
I think the frist one is correct, does anyone has clear idea and experience about it.

I want to create a simple application that transfers audio online through RTP. both the sender machine and receiver machine have public ip address. I tried JMStudio and AVTransmit2/AVReceiver2 without success till now! it drives me crazy. I really don't know what's wrong here. is there anyone really make it work?
even I can see the receiver machine keep receiving data through the port I specify to transfer data(the port is 22224), the JMStudio or AVReceiver2 on receiver machine just waiting for data, also I can see the statistic of JMStudio on sender machine reports transfer successful and the data keeping transferred. I also tried to use broadcast way, that is, changing the last part of sender's ip address to 255, still no luck! the receiver can't receive any data!
since I use Ubuntu, there is no firewall, no port is blocked. I can access from receiver to sender or vice versa using SSH. I don't think there is any connection problem, also I can see the receiver keeping receive data.
I transfer a mp3 file through RTP session. I installed mp3 plugin on both receiver machine and sender machine. I can play it using JMStudio on both receiver machine and sender machine locally.
could anyone kindly let me know how I should do, or if there is any very very simple java program to transfer anything using RTP on internet? could you please tell me your configuration if you happen to make it work?
any hint will great appreciate!
Samif you have a microphone in your pc, AVTranmit2 and AVReceive2 command should be:
on your own pc:
java AVTransmit2 dsound:// targetIP 42050
on target pc:
java AVReceive2 yourIP/42050
since the same port cannot be used simutaneously by two applications(avreceive2 and avtransmit2), the above command can only be used on two different pcs (your pc and target pc).
if you wanna execute AVReceive2 and AVTransmit2 on the same pc, you have to modify the source codes. I have done that.
commond
java AVTransmit2 dsound:// yourip 42050 42100
java AVReceive2 yourip/42050 yourip/42100

How to solve the problem "cannot create a datasink for **(datasource)"
There is a forums that can send and receive RTP streams, and it can play on the client. Now I want to save it. I write the code according to the jmf2_0-guide, how ever it always throws the exception "cannot create a datasink for **(datasource)". The datasource is the RTP stream received from the server. Is there anything wrong with the data source or anything else?
here is the code:
public synchronized void update( ReceiveStreamEvent evt){
if(evt instanceof NewReceiveStreamEvent){

Does any one know how to solve this problem? How to save or how to create a datasink? Please help! Thank you!!The complete error message:
NewReceiveStreamEvent exception Cannot find a DataSink for: com.sun.media.protocol.rtp.DataSource@4741d6 -
hello,
I was wondering if anyone had or if there is a simple client application out there which connects to a server and plays the rtp stream. I already have the server ready to go and I was hopeing I could find an easy client to use to display the video. I am currently using JMStudio as the client which turns out to be a bit ugly. Are there alternatives?import java.io.*;
