How to read sequence numbers from RTP packets

hi everyone.
i want to know how to read sequence numbers of RTP packets. I will need that to reconstruct my stream from packet losses.
URGENT Help needed!!

The StreamTokenizer parses all numbers into only one type of value, a double. If you know that all the numeric values in the file will be integers, you could just cast the nval double field to an int and the toString() method will format it correctly.
If you want to have different tokens and value types for different kinds of numbers, you will have to sub-class StreamTokenizer and add these capabilities yourself. You can add the type constant TT_INT, and provide an int field named ival. The toString() method would then format the value in the correct manner.
If, on the other hand, you are actually looking for the exact text that was parsed, you could add code that collects the characters as they are parsed for any token type into the sval field in the nextToken() method, just like it already does when the token is a TT_WORD. In this manner sval is always valid for any token type.
I hope you find this of some help.

    If you mean spreadsheets from within the Numbers app on your iPad to your computer's iTunes then there are instructions here. If you mean that you want to copy the Numbers app from the iPad to your computer then you can copy it to your computer's iTunes via File > Transfer Purchases; but if you want to use Numbers on your Mac then you will need to buy the Mac OS X version.

  • How to read Group ID from Value Mapping Context in Cache Monitoring ?

    Hi friends,
        In RWB --> Cache Monitoring --> Integration Server (Java) -> (Search for Value Mapping Groups) in this each item is identified by Value Mapping Group (GroupID, Context, Identifier/Agency, Identifier/Scheme). Either we create Value Mapping Table in ID or replicate value mapping data directly from text file/SAP table etc., in run time cache, data will be identified in this manner.
        Now, our requirement is to delete a record the Cache for a particular context. Two operations provided by XI one is 'Delete' and another one is 'DeleteGroup'. When we use either of this, we should know GroupID. Suppose, I replicated some large amount of data from my text file in Runtime Cache. Value Mapping Table is like that IN --> India, US --> USA, AU --> Australia, EG --> Egypt. Now, I am required to write a program to get the input country code from user which is going to delete in the value mapping table like IN/AU....  For this, what logic we should follow in the program is, First we scan the value mapping table and find the record (country code)  which is match with the input. Then find the GUID value for this record. Now we use the DeleteGroup Operation and pass this GUID and then delete the record.
        So, in essence, how to read the GUID from value mapping context.
        Friends, Kindly help me to do this.
    Thanks in advance.

  • How to read appended objects from file with ObjectInputStream?

    Hi to everyone. I'm new to Java so my question may look really stupid to most of you but I couldn't fined a solution by myself... I wanted to make an application, something like address book that is storing information about different people. So I decided to make a class that will hold the information for each person (for example: nickname, name, e-mail, web address and so on), then using the ObjectOutputStream the information will be save to a file. If I want to add a new record for a new person I'll simply append it to the already existing file. So far so good but soon I discovered that I can not read the appended objects using ObjectInputStream.
    What I mean is that if I create new file and then in one session save several objects to it using ObjectOutputStream they all will be read with no problem by ObjectInputStream. But after that if in a new session I append new objects they won't be read. The ObjectInputStream will read the objects from the first session after that IOException will be generated and the reading will stop just before the appended objects from the second session.
    The following is just a simple test it's not actual code from the program I was talking about. Instead of objects containing different kind of information I'm using only strings here. To use the program use as arguments in the console "w" to create new file followed by the file name and the strings you want save to the file (as objects). Example: "+w TestFile.obj Thats Just A Test+". Then to read it use "r" (for reading), followed by the file name. Example "+r TestFile.obj+". As a result you'll see that all the strings that are saved in the file can be successfully read back. Then do the same: "+w TestFile.obj Thats Second Test+" and then read again "+r TestFile.obj+". What will happen is that the strings only from the first sessions will be read and the ones from the second session will not.
    I am sorry for making this that long but I couldn't explain it more simple. If someone can give me a solution I'll be happy to hear it! ^.^ I'll also be glad if someone propose different approach of the problem! Here is the code:
    import java.io.*;
    class Fio
         public static void main(String[] args)
              try
                   if (args[0].equals("w"))
                        FileOutputStream fos = new FileOutputStream(args[1], true);
                        ObjectOutputStream oos = new ObjectOutputStream(fos);
                        for (int i = 2; i < args.length ; i++)
                             oos.writeObject(args);
                        fos.close();
                   else if (args[0].equals("r"))
                        FileInputStream fis = new FileInputStream(args[1]);
                        ObjectInputStream ois = new ObjectInputStream(fis);
                        for (int i = 0; i < fis.available(); i++)
                             System.out.println((String)ois.readObject());
                        fis.close();
                   else
                        System.out.println("Wrong args!");
              catch (IndexOutOfBoundsException exc)
                   System.out.println("You must use \"w\" or \"r\" followed by the file name as args!");
              catch (IOException exc)
                   System.out.println("I/O exception appeard!");
              catch (ClassNotFoundException exc)
                   System.out.println("Can not find the needed class");

    How to read appended objects from file with ObjectInputStream? The short answer is you can't.
    The long answer is you can if you put some work into it. The general outline would be to create a file with a format that will allow the storage of multiple streams within it. If you use a RandomAccessFile, you can create a header containing the length. If you use streams, you'll have to use a block protocol. The reason for this is that I don't think ObjectInputStream is guaranteed to read the same number of bytes ObjectOutputStream writes to it (e.g., it could skip ending padding or such).
    Next, you'll need to create an object that can return more InputStream objects, one per stream written to the file.
    Not trivial, but that's how you'd do it.

    How to read a string from a file and assign the value to a variable then return the value to the screen in windows batch file?
    Any suggestions?
    thanks.

    Unless this is a homework question then I don't see the purpose of doing this, but....
    You should be looking a the supplied package utl_file to get the string out of the file, dbms_output to display the string and then google windows batch/command files calling sqlplus to execute your program.

    Hello Tao,
    The parameter
       icm/HTTP/file_access_<xx>
    may help you to access the pictures without any db-access.
    The following two links may help you to understand the other possibilities as well.
    The threads are covering BSP, but it should be useful for WebDynpro as well.
