Assuming 172.16.106.160 1500 like the remote Host IP. I recommend you try this:java AVTransmit2 file:/someMediaFile 172.16.106.160 1500java AVReceive2 172.16.106.160/1500If AVReceive2 deesn't receive nothing, tryAVReceive2 SenderIP/1500Hern醤.

Hello sir
I have used the options which you have suggested but it is not working. The same problem is there.
172.16.106.160 is the IPAddress of receiving machine(I have used it as a parameter in AVTransmit file)
172.16.106.140 is the IPAddress of Sending machine(I have used it as a parameter in AVReceive file)
and 1500 is the port I am using.
When I am using SenderIP it is giving error.
I have also used RTPServer3.java and RTPPlayer2.java files. Same problem is there waiting for RTP data.
Please Reply me soon sir I have to submit my project.
Thanks alot.

1st try using JMStudio on BOTH machines
Assuming that works
use your Transmitter settings on the 1st machine & prove that JMStudio can receive on 2nd machine
Assuming that works
use your Transmitter settings on the 1st machine & now your Receiver settings on 2nd machine - (this is likely not to work as this seems to be what you have got at the moment)
BUT if the 1st two steps work then you will have narrowed the problem down to the receiving side of your system
If the 1st step works & the 2nd doesn't perhaps you should post up some of your code for us to take a look at - (try to reduce it to the core code that exhibits the problem)
ps have you tried starting the Receiver code before the Transmitter & also the other way around

Sir
I have checked JMStudio on both the machines. It is working by simply playing the audio file.
But you are right there is same problem waiting for data when on one
machine I am transmitting and on other machine receiving using JMStudio directly.
I am doing the following
On one machine- Open JMStudio->transmit->select file->specyfy IPaddress of other machine with port no->finish->uncheck the monitor audio
On second machine- Open JMStudio->Open RTP session->specify IPAddress of first machine(sending machine) with same portno.
But now messagebox is showing waiting for data. 7,8,9....... second elapsed.
What it means there is some problem. I have done both I mean starting second JMStudio first and vice versa.
Please suggest what should I Do?
Thank you very much

Hi,
I had the same problem and I solved it.
Try to disable the Firewall of the server computer (transmissor of the RTP).
The client computer don't need to have the firewall disable, but, if you need to enable that the client computer also transmit, you need to disable the firewall.
Please, report if you have success!
Regards..

Thanks alot for your reply
I have disabled the firewall. But now the new problem is there.
When I use JMStudio at the receiving end, and click on open RTP Session. After specifying the IPAddress of sending machine and portno. following error message is showing
Controller error
Internal Module com.sun.media.BasicRendererModule@3a5794:
Failed to handle a data format change.
And when I use command prompt for executing RTPPlayer2.java file or AVReceive2.java file following error shows-
Error in ControllerErrorEvent:
javax.media.ControllerErrorEvent [source=com.sun.media.content.unknown.Handler@b1c260, message=Internal Module com.sun.media.BasicRendererModule@228a02:
Failed to handle a data format change
Plese suggest me what to do now. Its my bad luck when one thing goes right another thing does not work.
Please sir inform me soon.
thanks alot.

Hello sir
I have tried with various formats of files. like-wmv,wma,mp3,MPEG it is not transmitting any of these type of files. It is only transmitting the wav file.
Also it is playing MPEG file but when I transmit MPEG file to other computer The same problem is there Waiting for data on the receiving computer.
And it is playing MP3 file but when I transmit that mp3 file error is there-
ControllerEvent Handler - unable to handle data format change.
Please inform me the extensions of files which it supports to transmit.
Please reply me soon.

Hello sir
I have to convert audio/video file format into RTP Packet format(concedering all the parameters) to transmit packets to another cother computer.
For example JMF uses RTP formats like RAW/RTP and more.
Please inform me what are the performance parameters for this format. And how to convert existing format into this one.
Please provide me source codes for this.
I will be very thankful to you.
Thanks alot.
