Unreliably receiving NewParticipantEvent, ByeEvent
My JMF RTP client connects to the sending RTP server and successfully opens the ReceiveStreams and creates a player.
The problem is that sometimes it does not receive the ByeEvent when the server-side RTPManager's removeTargets() is called, thus the client never finds out the server is done transmitting. I have come across other desperate posts mentioning the exact same problem, but haven't found a solution listed for any of them.
The only other piece of information I have to add about this phenomenon is that the times when the ByeEvent was not received, the NewParticipantEvent had never been received either. This leads me to believe that either:
A.) the RTPManager (on the client side) only acknowledges ByeEvents from known participants, and since it didn't receive a NewParticipantEvent from the server-side (which would map the participant with a stream), it doesn't fire a ByeEvent, even when it receives the event on the RTP stream, or
B.) the RTPManager on the server side is simply not firing events to this client.
It is important to note that the behavior (not receiving these events on the client side), is sparatic: i.e. on some runs, it will receive the NewParticipantEvent and subsequently receive the ByeEvent when the server side closes the stream, and other runs (back-to-back, using the exact same build) it does not receive the NewParticipantEvent, thus doesn't receive the ByeEvent, and the client never knows the stream is finished.
I know this behavior has been seen before (from looking through past forum posts), but has anyone found a solution?
I think beta version3 of JMF fixed that problem. Visit http://java.sun.com/products/java-media/jmf/2.1.1/features.html
Look under the beta3 bug fixes and you'll see "bye event issue" a confirmed bug in the earlier versions. Maybe you might want to download a newer release of JMF.
I'm not very expert in Java, but I'm developing a video conferencing software myself. I might have a suggestion for you. Maybe you might want to use an extra port on each side to transmit data only. This way you can transmit a message on that extra port when the client is disconnected, connected and interpret that message on the server side to dispose your RTPManagers or fire events. And vice versa. You can basically listen for applet close or button action events to determine end of receivestream on client side, or even ping the server every once in a while to assure the connection is there using this extra port. It's more of an effort than simply listening to the "bye" event but, I hope that makes sense, it's just an idea. (I hope your application is not a port monster on server side)
If I can resolve my syncronization problems with starting, dealocationg and restarting my processors, I'll be having the same headache as you're having in a few days. So keep us posted if you find anything.. [email protected]

Unreliable receiving hotmail from other hotmail users
Is there a temporary problem with receiving mail from Hotmail at the moment? Im not talking about plug ins for my own hotmail account, I dont have anything set up, but hotmail from other people seems to be in transit for hours, and sometimes doesnt arrive! I have tried experimenting with gmail, and it arrives more or less as expected. But hotmail! I am still waiting for mail I know has been sent (half an hour, 8 hours..). My fiancee thinks I am ignoring her!
ThanksIf you are accessing your Hotmail account via webmail with a browser or with the Mail.app using the Hotmail plugin, Apple has nothing to do with this.
Apple is responsible for the incoming and outgoing servers for .Mac email accounts only.
Any problems sending or receiving email with a Hotmail account are caused by Microsoft servers or a temporary problem in transit between various servers. -
hello,
i'm trying to create a J2SE VoIP app with JMF. is it feasible?
i've read that to overcome the NAT problem, we need to use Symmetry RTP. does it supported in JMF?
i've done the SIP session managing with JSIP. now i need to send and receive RTP data.
i've done this for the receiver
url= "rtp://" + IP + ":" + port + "/audio/16";
mrl= new MediaLocator(url);
player = Manager.createPlayer(mrl);
player.realize();
// wait for realizing
while (player.getState() != Player.Realized){
try
Thread.sleep(10);
} catch (InterruptedException e)
e.printStackTrace();
player.start();
with IP is the other party IP specified in the SDP, and the Port is the port specified in the SDP too.
with wireshark, i've seen that RTCP is seen (Receiver Report, Source Description), and RTCP replies are received (Sender Report, Source Description), but RTP data is not received.
i realize that JMF open the same local port as the port specified in the MediaLocator. while actually in my INVITE SDP, i tell the other party a different port. might this be the problem that i don't receive any RTP data?
Thank you.Hey,
No, the loss of packets isn't something you can control... you lose a packet, you lose a packet. The different encodings could have an affect on the impact of the packet loss, however, but the actual loss of the packet is out of everyone's hands. Even God loses packets as they travel on the wire...Well, I went again to Wiki to look for that page and you are right, I am wrong, it didn't say anything about packet loss, but it was referring to the call distortion and wrongly concluded something about the packets.
Ummmm, maybe. The issue isn't as simple as knowing the public IP address of a client behind a NAT, it's also a matter of traversing the NAT itself. But if the SIP UAS handles all of that, then yes, you should be fine.after putting it to the test, I'm really confused...
I'll try to lay it out so it would make sense and if that wont work I'll post my code here. there is just a lot of it in a few classes.
This is tested with one way streaming!
*1.* I've been trying to transmit audio and video within my home LAN, I've managed to send from one computer to the other, from beginning to end.
This is what I receive on the callee computer in my home LAN:

- Recevied new RTP stream: JPEG/RTP*2.* But when I try to transmit to my friends computer, which is far far away... I do receive NewParticipantEvent, and I do get StreamMappedEvent, but no NewReceivedStreamEvent. sometimes I received an InactiveReceivedStreamEvent but to the caller computer, not to the callee. I thought perhaps the log would help:
This is what I get when I try to call my friends remote computer, on his computer:

- A new participant had just joined: TacB0sS@dell-laptop

What am I missing?

Unreliable behavior of MulticastSocket's receive method
I have a program that uses one MulticastSocket to receive packets from a multicast address on a given port (running on a dedicated thread), and another MulticastSocket to send both multicast- and unicast-adressed packets from the same port (running on a separate thread). The program runs on a Windows system that communicates with a separate program (written in C++) running on a Linux system (more specifically, a Gumstix processor running Ubuntu). Both applications are written to send some messages by multicast, and others by direct unicast, with all sending and receiving being performed using the same port number.
The problem I'm having is this... The MulticastSocket SOMETIMES receives packets sent by the remote system by BOTH multicast addressing AND unicast addressing, but other times, ONLY receives the packets sent by multicast addressing. By "sometimes" and "other times," I mean "distinct executions of the program." That is, if I run it one time, the MulticastSocket ALWAYS behaves one way, and if I run the same program again, it ALWAYS behaves the other way.
I know that this smacks of thread-interaction issues, but I have done due diligence to rule this out as best I can.
All of the documentation about MulticastSocket says that it is perfectly reasonable to create multiple MulticastSockets on the same socket address (i.e., the same port), by virtue of the fact that the class sets SO_REUSEADDR to true by default. But if the code never instantiates the sending MulticastSocket, the receiver seems to receive unicast-addressed packets quite reliably.
How can I ensure that the receiving MulticastSocket behaves in a predictable manner? Are there known issues with this?I don't understand why you're using two MulticastSockets for this. You can send and receive from the same MulticastSocket simultaneously.

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.

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,

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.

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.

Memory Leak, Receiver Got Null Message & Consumer limit exceeded on destina
When running program that adds an Object message to a JMS queue and then recieves it. I get the following.
1) interminitent NULL messages recieved.
2) jms.JMSException: [C4073]: Consumer limit exceeded on destination interactionQueueDest. Even though only one receiver can be receiving via the supplied program.
3) After many message are added to the queue 1000's the Message Queue goes to Out Of Memory exception. It should swap to disk!!

}Is there something wrong with the way I'm working with JMS or is it just this unreliable in Sun App Server 7 Update 3 on windows?1) interminitent NULL messages recieved.Thanks that explains the behavior. It was wierd getting null messages when I know there is messages in the queue.
2) jms.JMSException: [C4073]: Consumer limit exceeded
on destination interactionQueueDest. Even though only
one receiver can be receiving via the supplied
program. No other instances, Only this program. Try it yourself!! It works everytime on Sun Application Server 7 update 2 & 3
heres the broker dump at that error point

Broken pipe error in Sync Send JDBC Receiver: Extremely Serious issue
Hi forum,
I have a serious error in a JDBC->XI--> JDBC scenario,
Step1: I use a sender JDBC channel to select some distinct values from a table say X, and update the same rows,
Query SQL Statement: select distinct Branch from dbo.X where status = 0
Update SQL statement: update dbo.X set Status = 2 where Status = 0
Step 2: enter BPM
Step 3: enter a loop
Step 4:make a synchronous call to the same table X, to fetch some records,
SQL query: select * from X where status = 0 and Branch = i; Update X set status = 9 where Branch = i
Step 5: close loop, this loop iterates for 5 or 6 times depending on i, which is no. of branches selected by the sender JDBC channel
so all the calls are to the same table, same databsse(SQL Server)
the problem is when this sync calls happens in the loop, it some times gives following error, which i se in RWB:
<b>Error Unable to execute statement for table or stored procedure. 'X' (Structure 'STATEMENT_X') due to com.microsoft.sqlserver.jdbc.SQLServerException: An exception occurred during the DBComms.transmit operation. Exception:Broken pipe (errno:32). Context:(2217)</b>
i have no way to trace the cause of the error, the database is perfect and the error logs in the SQL server shows no trace of any error,
Note: It works sometimes

SAP Note 846079 - XI 3.0 JDBC Receiver: # of Retries on SQL Error w/o Effect
Please check the following SAP note also - 831162
Some info which i found there and can be relevant in to your scenario.....
Q: I am using a JDBC Receiver Adapter in conjunction with the Lotus Domino Driver for JDBC perform an INSERT or UPDATE operation on a database. When sending a message to the receiver, the Adapter Monitoring shows the following error message:
"java.sql.SQLException: [Lotus][Domino Driver for JDBC]Invalid cursor state"
Is there a fix for this issue?
A: To work around this JDBC driver problem, activate the Advanced Mode for the respective JDBC Receiver channel and configure the setting "Number of Retries of Database Transaction on SQL Error" to a value > 0. Additionally, make sure that the setting "Database Auto-Commit Enabled" is also active as the Lotus Domino Driver for JDBC does not support transactions.
Apply note 846079 before configuring this scenario.
Q: The TCP/IP connection to my database host is running over an unreliable network connection, i.e. the connection is sometimes interrupted. Consequently, I sporadically receive an SQLException regarding a closed connection in the system trace or audit log or the connection as well as the JDBC Adapter channel are hanging.
How can I work around this connectivity issue?
A: Enable the "Advanced Mode" for the respective JDBC Adapter channel and select the option "Disconnect from Database After Processing each Message".
Note that this might put additional load on your DBMS due to the creation of a new database connection for each message.
I dont have access to a database right now, so i am not able to check this.
Also check the JDBC driver compatability as mentioned in the above note.

Ideas.It's not that you can't use the subject field, but it is very unreliable when I try to use it. Sometimes the message send button will work and sometimes it won't.
But the biggest reason to turn it off is so that you do not accidentally type your message in the subject field. You can type a subject in that field, but you still have to type the actual message in the space below the subject field. -

Skype 5.0.0.52727
Today I turned on mobile data on my phone (I don't use it otherwise due to ridiculous costs) and started Skype (I run it usually over WiFi).
I noticed that it receives messages only when in foreground. Otherwise minutes pass and there is no notification of any incoming messages.
Only if I open the Skype app, does it detect new messages. But even that is unreliable. I takes up to a minute for messages to appear. It only works like expected (messages are detected with less than a second delay) when a conversartion with the sender is open.
This makes Skype pretty much useless, as one has to guess that a message was sent and manually open Skype, also must know who sent it, and oopen a conversation with that contact.
I use mostly default settings (both in Skype and system).
Regards,
DavidI'm having similar issues on my Nexus 5, Skype version 5.0.0.55107.
Most of the time I'm connected to the wi-fi network, then I usually have no problems with recieving calls and messages immediately, but if I swith to a cellular network and mobile data, then messages come later or only when I open skype itself.
By the way, I've noticed the problem almost went away when I checked "Show Skype status as an ongoing notification", before that it seemed that it only worked on the foreground, and when I switched to other apps or the screen turned off, it just went offline. -
Why is the mail application so unreliable?
I have made my move to a Mac laptop this year after being overrun with iOS devices in my house. The MacBook Air I have is an awesome machine. One of the main things I got it for is for business productivity. The simplest of things I should be able to do is communicate over email, but the native mail application is so unreliable it is embarrassing. I have a yahoo account that I was able to setup fine enough. Every time I send an email it is a gamble as to whether or not it is sent or not. That is unacceptable. The mail accounts I setup on my iOS devices seem to be bulletproof and it boggles my mind that the mail client on the Mac OS is so bad. I wasted time with the support lines on several occassions and all they could tell me is tht sometimes after I send an emal it can get stuck in between sending and getting off the yahoo server so there is no record it has been sent and no copy in drafts. What an awful answer. It has gotten to the point where the only way I am confident to use email is on my iPhone or through the web browser on the yahoo site. I am really unhappy about this and would like to know if other people see the same problem.
I'm spending hours with the techies on my server, which is the cable company we contract with. First I kept getting the message that Mail didn't recognize the server but it would connect when I clicked Connect. Then it started letting me receive messages but not send. Now I can't do either, and the company has no help for me. I have run the disk utility verify and repair options and it tells me all is well.
I don't want my emails anywhere on the web, just here at home. The cable techs have gone over and over the technicalities on their end and have concluded that Apple Mail is the problem. I find evidence of that in much online grumbling, but here I find only self defense.
How could you help me?
1. Admit that your software has bugs. Tell me some things I could try to get my email working again. I'm finding such protocol elsewhere on the web but it all seems to relate to earlier versions of OSX.
2. Show me where I could upgrade to a less buggy version than 6.2. This is my second laptop in the past year (first one stolen) and each had different problems with Mail. The first one kept losing mail. Messages would come in and then be gone when I'd go to answer them. Important items I would not delete. That's not happening with this one -- it just keeps losing connection with my server.
Please stop pretending that anyone who has problems with Mail is afflicted in some way. There are problems, and I'm very shocked that Apple, who used to be one of the good guys (at least in my book), seems to to be stuck on a policy of self righteousness. Guys, your halo is tarnished with Apple Mail -- time to realize that and cope. -
Slow Boot, Unreliable WiFi, and Forced Shutdowns
Ever since I got my iMac, I've been having the same problems quite consistently for over a year now. The WiFi used to randomly drop out (as many others had also reported), but that was fixed. Except an OS update or two later and it's back (although it's different and not quite as bad). Anyway, here are all of the problems I've been having:
– iMac is slow to boot; sometimes it won't boot unless I unplug my Firewire cable. For a fully-upgraded iMac, it shouldn't take as long as it does (upwards of a minute). Sometimes, however, it won't boot at all. It will get stuck at a grey screen (or login screen when I have that set up) with the cursor visible. The computer will not continue to boot up or receive any input until I unplug my external Firewire hard drives.
– WiFi is somewhat unreliable. At times, my internet connection completely drops out despite having a full-strength signal. Oddly, it usually happens right after I start to use the internet after having been away for a while. In other words, it works great when I'm not at the computer (if, for example, I use LogMeIn), but as soon as I sit down at the computer, I can visit one website before it drops out on me. I end up turning WiFi off and back on again and hope that it works.
– Finally, I can't remember the last time I did a legitimate shutdown. Every single time I go to shut my computer down, it never does it by itself. If I let it do its thing, some app won't quit and will cancel shutdown. The only way I've been able to remedy the problem is by clicking Shut Down then force-quitting literally everything. I've read that the problem tends to be Mail as it tries to keep a connection with the mail servers, but it's been anything from App Store to Safari to iTunes. I have a problem report handy from when I last shut my computer down if that's worth posting.
Thanks for taking the time to help me figure this out!

How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?
