About the bug of QuickTime for using the header extensions of RTP header.

Dear Sir,
I try to receive the rtsp protocol streaming by using QuickTime Player 7.1.5. If I pad the "X-bits" , Header Extensions of RTP header information, QuickTime would be shutdown. why? thank you.

James -- you need to post your question in the QuickTime forum:

What is this error message about, "The system extension "/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt" was installed improperly and cannot be used"?

It appears as a window with the following text, "System extension cannot be used. The system extension “/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt” was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
I close it by clicking "Ok", and it doesn't seem to affect the system performance in any way, but it's annoying knowing that it's there. The problem is quite old, and has persisted through several OSX updates.

hello,
I have the same problem. does anyone have any ideas on what's going on and or how to fix it.
Thanks!!

Unsure about preparing a Dreamweaver Site for use with Contribute

Recently I designed a small Dreamweaver Website (DW CS2) for
a friend and it is already successfully online. So that my friend
can manage her own website, I`ve decided to prepare this DW site
for use with Contribute, but I'm unsure about the steps involved
and what files I will need to store on the server. Is the following
roughly correct?
Step 1: Define editable regions in these html files and save
these as html files.
Step 2: Enable Contribute Compatibility in DW before I upload
to the server.
Step 3: Is setting up a Connection Key necessary for my
friend`s access?
Step 4: Upload these. Do these completely overwrite the
existing Dreamweaver html files on the server? Or should I be
saving in another file format?
Many thanks to anyone who can advise me!

I sugggest these steps:
A: Dreamweaver:
1. build you site based on (a) template(s) with editable
regions
2. upload the website to the server
B: Contribute
1. create a connection
2. administer the website ( and create an admin password )
3. set the proper settings for your users (administrators,
publishers, writers), enable rollbacks
4. create a connection key fot you user with the proper role
and save that to disk
C: Dreamweaver
1. manage the site in dreamweaver
2. enable contribute compatibility (this way files get
checked in and out, so you know who is editing what)
D:
1. Sent the connection key to your user

How can i get more info about the sent data in RTP?

Hello.
I'm working with the examples AVTransmitt2 and AV Receive2 and i want to get more information about the data that it is being sent to de receiver side. In AVTrasmitt2 i only see a calling to processor.start();. How could i know each packet that AvTransmit2 sends to the other side. I want info like the size of the data, the quality, format, etc..

Hi!
As I mentioned above. RTPSocketAdapter has two inner classes, SockOutputStream and SockInputStream.
SockOutputStream have a write method which is called when RTP data is sent over the NET. SockInputStream have a read method which is called when RTP data is received.
If you for instance want to know exactly what is sent you can parse the byte array that comes into write.
Like this:
* An inner class to implement an OutputDataStream based on UDP sockets.
class SockOutputStream implements OutputDataStream {
     DatagramSocket sock;
     InetAddress addr;
     int port;
     boolean isRTCP;
     public SockOutputStream(DatagramSocket sock, InetAddress addr, int port, boolean isRTCP) {
          this.sock = sock;
          this.addr = addr;
          this.port = port;
     public int write(byte data[], int offset, int len) {
          if(isRTCP){
               parseAndPrintRTCPData(data);
          }else{
               parseAndPrintRTPData(data);
          try {
               sock.send(new DatagramPacket(data, offset, len, addr, port));
          } catch (Exception e) {
               return -1;
          if(debug){
               System.out.println(debugName+": written "+len+" bytes to address:port: "+addr+":"+port);
          return len;
private void parseAndPrintRTPData(byte[] data) {
     // part of header, there still left SSRC and CSRC:s
     byte[] rtpHeader = new byte[8];
     System.arraycopy(data, 0, rtpHeader, 0, rtpHeader.length);

     // sender's octet count
     int nbrOfSentBytes = buffer.getInt();
     System.out.println("sender's octet count: "+nbrOfSentBytes);
}I added a boolean isRTCP to the constructor so to know what sort of data is sent.
Hope this clarifies things.

How can I report or make a complaitn about the Safari Extension zoominto?

I installed the Safari extension zoominto and the very first time I used it it presented pornographic women at the bottom of the extension. Is there somebody I can complain to or make a report?
This is the website for the company: http://www.zoominto.com
Thanks

For anyone finding this thread, there are some quasi-malware Safari extensions in circulation. Do some research before installing any extension, and read the license agreement very carefully. If you don't understand it, don't install.

Workaround for using Oracle JDBC extension with WLS pooling

Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.

Eugene Voytitsky

Hello Eugene Voytitsky,
Thanks Eugene Voytitsky for your idea
I have tried the solution suggested by You, but it did not work.
It still throws ClassCastException.
I am sorry for posting the whole code of two classes below.
I did this to give you more clarity.
I am also indicating the place where the exception was thrown..
Please let me know if I am doing something wrong.

Question about saving JPEGs in Photoshop for use in FCP

Ah, Mr Stupit here, I don't see anywhere else to ask, and since the pics will be used in FCP I"ll try here.
In photoshop I rotated the pics to get the figure upright for ease of handling in FCP, and now I'm asked to save the pic and I'm given the choice of Baseline Standard, Baseline Optimized and Progressive, with Baseline Optimized being the default. Usually I go with the default, but now I figured I'd be clever and ask the geniuses here what they think: Which should I go with?
Another question, am I losing some quality by re-saving this JPEG? I don't want to get into whether I should save as Tiffs, I find my FCP struggles with such large sizes and I'm happy with the JPEGs. Of course, maybe that's why I'm Mr Stupit.

Thanks for the reply!
The problem when I save them as tiffs, png, etc is they become really large and when I open them in Viewer or place them in a sequence I have to wait and wait while the little balls spins. I'm thinking that maybe I'll just use the original JPEGs and rotate them in the Canvas. As long as I don't re-save them there shouldn't be any difference in quality between using them in FCP as opposed to re-saving them as Tiffs, etc, and then using them in FCP, right?
Sorry, but someone on another forum said just using JPEGs in FCP will result in a loss of quality though why should an untouched original somehow lose quality by being placed in an FCP timeline, I don't get it nor did I get an explanation.
I guess I'm Johnny Stupit & Confused.

Exporting High Quality Flash to Quicktime for use in FCP4.5

I am currently working on a interactive DVD production
including various Flash animations. I've tried exporting them as
almost every possible combination of compressions I could think of
using. Every time I import any clip (although seeming smooth in
previews or as stand alone clips...in both flash and quicktime
formats), they always seem to be choppy once imported into Final
Cut Pro 4.5, DVD Studiio Pro , or Motion !!! .
If anyone could give me some advice on what would be the best
compression to use within Flash's export functions , to then be
able to use within FCP 4.5 .... it would be very appreciated ! This
is tormenting me right now !!!!
Thx

You're probably already doing this but be sure that the Flash original files are the same image size and run at the same frame rate as the video that you want to edit into. When you export from Flash as Quicktime use the Apple none compression option. This will give you the best possible file to work with. If you don't see the none compression option you can follow this set of instructions: missing "none" compression in Quicktime 7.6.6 p... | Apple Support Communities

Buying official USA unlocked iPhone for use in the UK

Hey there - about the head over to the USA for a holiday and want to pick up an official Apple unlocked iPhone 4.
The specs say GSM - does this mean it doesn't have 3G at all? Will it work with a UK micro-sim on 3G or just EDGE?
Cheers!

"3G" is absolutely not standard; in fact, "3G" as a term is essentially meaningless; it's mostly a marketing term and does not convey anything definite in terms of technology. "GSM" is a more informative term, being the connection technology used by many cell carriers, but even there differences can be found. In the US, AT&T and T-Mobile both use GSM but use different frequencies; the US iPhone doesn't support the frequencies T-Mobile uses except for EDGE (an older, slower technology).
Important note: the warranty on the iPhone is not world-wide. So you if you buy a US iPhone and it needs to be serviced, you will probably have to ship it to your US relative to send/take to Apple to get it serviced. Just so you know.
Regards.

Very simple question about the turtle

I'm kind of new to java, and I'm currently working on a university project involving the wellknown java turtle. Does any of you know how to change the turtle into another thing, like replacing the drawing of the turtle with a jpeg for instance? (I am using Guzdials turtle class)
Thanks for helping!

How to Modify the Header/Footer that's created when printing to PDF?

Hi all,
How do I modify the header/footer that is added when I use the Adobe PDF printer in another application, like MS Word? Currently it adds the entire path of the file as the header, which is really annoying.
I'm not talking about the Header/Footer command in Acrobat's "Document" menu. In fact, that command doesn't even recognise the header that's generated by the Adobe PDF printer.
I'm using Acrobat Pro 8.1.3, btw.
Thanks :)

Generally you should set the whole look of the page in your application and then print to the Adobe PDF printer as you have been doing. If you are using a browser, there are header and footer commands for the printer that are typically set by the browser - those can be modified there. The PDF should look just like the preview in the application, that is the point of a PDF.

Selection groups for tables and header tables

A couple of questions or rather observations around Selection Groups for tables and conversion objectu2026
1) For tables that do not really have a date field, for instance table PDSNR, it appears that you cannot specify a selection group. Consequently, you have to transfer the table in its entirety. Is this something that can be modified via customizing?
2) And what about the header tables, for example, X_ANLC, I have tried but not able to change the selection groups on these objects.
Thanks!

Hi Harmeet.
Since you mention you can only filter by date I am assuming you are using TDTIM.
How would you want to filter PDSNR, for example? Would it want to filter all entries >= a given sequence number?
The only way I know to do that is to work directly with the configuration tables. In your case you will need to use CNVMBTSEL* tables. Check how the standard selection groups are configured, and it should not be too difficult to follow the same logic and create your own selection groups.
CNVMBTSELGRP                   MBT PCL Selection groups              (main table to create the selection group)
CNVMBTSELMEMTYPE               MBT PCL Selection group member types (main table to define members => fields for the selection group)
CNVMBTSELGRPDEF                MBT PCL Selection group definition    (definition of the fields in that selection group)
CNVMBTSELGRPVAL                MBT PCL Selection group values        (values for each field; you can use GE for >=)
CNVMBTSELCLAUSE                MBT PCL Selection group clause        (should also be straightforward if you are using only one field)
CNVMBTSELVAR                   MBT PCL Selection group variants     (configure the same variant for your selection group as for the others)
CNVMBTSELREF                   MBT PCL Selection group reference     (assignment of selection group to conversion object)
Hope this helps,

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.
In particular, I am analyzing the example "Even Angle Reference Signal Processing (Digital Tacho, DAQmx).vi", whose documentation I am reproducing in the following:
DESCRIPTIONS:
This VI demonstrates how to extract even angle reference signals and remove the slow-roll errors. It uses DAQmx VIs to acquire sound or vibration signals and a digital tachometer signal. This VI includes a two-step process: acquire data at low rotational speed to extract even angle reference; use the even angle reference to remove the errors in the vibration signal acquired at normal operation.
INSTRUCTIONS:
1. Run the VI.
2. On the DAQ Configurations tab, specify the sample rate, samples per channel, device and channel configurations, and tachometer channel information.
NOTE: You need to use DSA PXI-447x/PXI-446x and PXI TIO device in a PXI chassis to run this example. The DSA device must be in slot 2 of the PXI chassis.
3. Switch to Extract Even Angle Reference tab. Specify the number of samples to acquire and the # of revs in reference which determines the number of samples in even angle reference. Click Start to take a one-shot data acquisition of the vibration and tachometer signals. After the acquisition, you can see the extracted even angle references in Even Angle Reference.
4. Switch to the Remove Slow-roll Errors tab. Click Start to acquire data continuously and view the compensate results. Click Stop in this tab to stop the acquisition.
ORDER ANALYSIS VIs USED IN THIS EXAMPLE:
1. SVL Scale Voltage to EU.vi
2. OAT Digital Tacho Process.vi
3. OAT Get Even Angle Reference.vi
4. OAT Convert to Even Angle Signal.vi
5. OAT Compensate Even Angle Signal.vi
My question is: How is the synchronization produced at the time of the compensation ? How is it possible to eliminate the errors in a synchronized fashion with respect to the surface of the shaft bearing in mind that I am acquired data at a low rotation speed in order to get the "even angle reference" and then I use it to remove the errors in the vibration signal acquired at normal operation. In this application both operations are made in different acquisitions, therefore the reference of the correction signal is lost. Is it simply compensated without synchronizing ?
Our application is based on FPGA and we need to clarity those aspects before implementing the procedure.
Solved!

Is there a way to roll back ios6? I upgraded before I knew about the new mapping. I used google maps all the time and absolutely hate the new one. Just about everything I've looked for is wrong or missing.

I hate the mapping in IOS6. Is there a way to roll back to the older OS? When I upgraded I didn't know about the mapping change. I used google maps a lot, for a variety of things. In just a few searches I've found more errors or missing landmarks than anything else. I really hate this app!

I agree. How can I roll back to the previous OS? Developers, please post a procedure for reverting.
