Newbie trying to understand the frame/fields per second concept on video

Do video camera shutter speeds (1/60sec) reflect an interlaced field or a full frame comprised of two interlaced fields per part of a second.
I suspect that a shutter setting of 1/60sec means it's not a full frame of video but is just an odd or even lined interlace field. Meaning that if I want to shoot 30fps I need to keep my shutter setting on 1/60sec.
But if that's really the case, then what am I exactly shooting per second if actual NTSC frame rate is 29.97fps? I mean, the first 2p frames can easily be divided into two fields each, but what about the remaining .97frame. How can you divide that into two fields of interlaced video lines?
Forgive my ignorance but books have a bad habit of not answering back when you don't understand something they say.
iMac Intel Duo-Core; Intel Mac mini single-core Mac OS X (10.4.6)
iMac Intel Duo-Core; Intel Mac mini single-core Mac OS X (10.4.6)

The shutter speed is not relevant. I can be either field based or progressive. The frame rate is not dependent on the shutter speed.

Trying to Understand the PostSyncCleanup parameter

I've got a problem with running my application on the Australian version of Windows. We have a "test" application built around SQL Server Compact Merge Replication Library (thanks ErikEJ) and that works but our application doesn't.
One of the main differences with our application code is that we do not set the PostSyncCleanup value to anything and the library sets it to 2 per this link:
http blogs.msdn.com/b/sqlblog/archive/2009/04/15/sql-compact-performance-postsynccleanup-to-turn-off-updatestatistics-during-initial-download-of-sql-compact-replication.aspx (put the :// back to get the link)
I'm trying to understand the impact of making that our "production" configuration since we haven't been using it. The description looks harmless enough but I don't really understand what statistics I'm turning off and what the impact
would be and what even the default setting is. Anything that could enlighten me would be appreciated along with a guess as to why that might be causing a problem on the Australian version of Windows would be appreciated.

So we've been running with the default value (0) and have not really had any "problems". I haven't done any testing but I'm ok with faster, like everyone would be, but am also a bit risk averse so want to know what exactly I'm turning off.
I also saw this advice from Rob Tiffany:
Use the appropriate x64, x86 or ARM version of SQL Server Compact 3.5 SP2 to take advantage of the
PostSyncCleanup property of the SqlCeReplication object that can reduce the time it takes to perform an initial synchronization. Set the
PostSyncCleanup property equal to 3 where neither
UpdateStats nor CleanByRetention are performed.
Here: http robtiffany.com/microsoft-sql-server-compact-3-5-sp2-has-arrived/
So, is the best advice to use that parameter and set the value to 3 or 2
I don't really know what I'm losing to "not performing" UpdateStats or CleanByRetention and does making that change need I need to do something else on the server or client to "clear out" or "clean up" something that this is
doing.

[SOLVED] Trying to understand the "size on disk" concept

Hi all,
I was trying to understand the difference between "size" and "size on disk".
A google search gave plenty of results and I thought I got a clear idea about
it.. All data is stored in small chunks of a fixed size depending on the
filesystem and the last chunk is going to have some wasted space which
will *have* to be allocated.. Thus the extra space on disk.
However I'm still confused.. When I look at my home folder, the size on disk
is more than 320 GB, where as my partition is actually less than 80 GB, so
I guess I'm missing something.. Could somebody explain to me what does
320 GB of 'size on disk' means?
Thanks a lot in advance..

Hi all,
Thank you for your replies.. My file manager is indeed pcman fm and
indeed it seems to be an issue.. In b4data's link the last post reads:
B-Con wrote:
FWIW, I found the problem. (This bug is still persistent in v0.9.9.)
My (new) PCManFM bug report is here: http://sourceforge.net/tracker/index.ph … tid=801864
I submitted a potential patch here: http://sourceforge.net/tracker/?func=de … tid=801866
Bottom line is that the file's block size and block count data from the file's inode wasn't being interpreted and used properly. The bug is in PCManFM, not any dependent libraries. Details are in the bug report.
Since PCManFM is highly used by the Arch community, I figured I should post an update here so that there's some record of it in our community. Hopefully this gets addressed by the developer(s) relatively soon. :-)
I guess that pretty much explains things.. And I think I did understand the 'size on disk' concept
anyway
Thanks again!

Trying to understand the sound system

Here's my problem. My mic didn't work (neither the front mic nor the line-in in the rear), so after some research and trial and error I found that if I do
modprobe soundcore
my mic works on both the jacks
But here's where my confusion lies. This is the output of lsmod |grep snd before probing explicitly for soundcore
[inxs ~ ]$ lsmod |grep snd
snd_hda_codec_analog 78696 1
snd_hda_intel 22122 1
snd_hda_codec 77927 2 snd_hda_codec_analog,snd_hda_intel
snd_hwdep 6325 1 snd_hda_codec
snd_pcm_oss 38818 0
snd_pcm 73856 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer 19416 1 snd_pcm
snd_page_alloc 7121 2 snd_hda_intel,snd_pcm
snd_mixer_oss 15275 2 snd_pcm_oss
snd 57786 8 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
soundcore 6146 2 snd
[inxs ~ ]$
So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
Go here:
http://kernel.org/pub/linux/kernel/people/tiwai/docs/
and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

Trying to understand the code???

Hi,
I am trying to understand the following bit of code, currently the code puts each catalogue into a different row of the table but i want each catalogue to be put in the next column
(so the catalogues appear across the page on the actual web page). The following code is for the page in question but im not sure how much is relevant so i will paste it all and highlight the section i think is relevant:

   String resourcePath = bean.getResourcePath(null);
   String title = "Product catalogue";

thank you for your help

You've probably already seen these, but here are a couple of links that may help.
http://help.adobe.com/en_US/FlashPlatform//reference/actionscript/3/operators.html#array_a ccess
http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/Array.html
What's basically happening is that the "for" loop goes through each item in the array. Don't be confused by the fact that two of the items in the array are Strings and one is an Integer - variable i being a String has nothing to do with the data type of the elements in the array.
The following code:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:String in myArray)
          trace("i = " + i);
          trace(myArray[i]);
gives the following results:
i = 0
one
i = 1
two
i = 2
3
From that we can see that the "for" loop is assigning the index number of each array element, not the actual array element ('one', 'two', or 3) to the variable i. So calling myArray[i] is the same as calling myArray[0] the first time through the loop. This type of "for" loop is just a shorter way of doing the following, which produces exactly the same results:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:int = 0; n < myArray.length; i++)
          trace("i = " + i);
          trace(myArray[i]);
Hope that helps.
Cheers!

Trying to understand the basic concept of object oriented programming.

I am trying to understand the basic concept of object oriented programming.
Object - a region of storage that define is defined by both state/behavior.
( An object is the actual thing that behavior affects.)
State - Represented by a set of variables and the values they contain.
(Is the location or movement or action that is the goal that the behavior is trying to accomplish.)
Variables- (What does this mean?)
Value - (What does this mean?)
Behavior - Represented by a set of methods and the logic they implement.
( A set of methods that is built up to tell's the how object to change it's state. )
Methods - A procedure that is executed when an object receives a message.
( A very basic comand.For example the method tells the object to move up, another method tells the method to go left. Thus making the object move up/left that combination is the behavior.)
Class - A template from which the objects are created.
( I am very confused on what classes are.)
- The definitions of the words I obtained from the "Osborne Teach Yourself Java". The () statements are how I interperate the Mechanisms (I do not know if Thats what you call them.) interact with each other. I understand my interpretation may be horribly wrong. I will incredibly appreciate all the support I may get from you.
Thank you

Object oriented programming is a replacement for the older idea of procedural programming (you can research procedural programming in google). As I understand it, in procedural programming, you have a step by step set of function calls to accomplish some task. Each function receives a data structure, manipulates it, and passes it to the next function. The problem with this is that each function preforms some action for the overall task and can't easily be reused by some other task. Its also harder to read the flow of what is happening with raw data structures flying all over the place.
In object oriented programming, an object calls a function of another object and receives back, not a data structure, but another object. Objects contain a data structure that can only be accessed by its functions. An object is not so much a sub component of a bigger task, as it is a service that any other task can use for any purpose. Also, when you pass an object to the caller, the caller can ask questions about the data structure via its functions. The developer doesnt have to know what the previous function did to the data by reading up on any documentation, or having to reverse engineer the code.
I suggest the best way of learning this is to code something like a library object.
A library object contains a collection of book objects
A book object contains a collection of chapter objects
A chapter object contains a collection of paragraph objects
A paragraph object contains a collection of sentence objects
A sentence object contains a collection of word objects.
Add functions to each object to provide a service
Example: A library object should have a:
public void addBook(Book book)
public Book getBook(String title)
public boolean isBookInLibrary(String title)
The key is to add functions to provide a service to anyone who uses your object(s)
For example, what functions (service) should a paragraph object provide?
It shouldn't provide a function that tells how many words there are in a sentence. That function belongs to a sentence object.
Lets say you want to add a new chapter to a book. The task is easy to read
if you write your objects well:
Sentence sentence1=new Sentence("It was a dark and stormy night");
Sentence sentence2=new Sentence("Suddenly, a shot ran out");
Paragraph paragraph=new Paragraph();
paragraph.addSentence(sentence1);
paragraph.addSentence(sentence2);
Paragraphs paragraphs=new Paragraphs();
paragraphs.addParagraph(paragraph);
Library library= new Library();
library.getBook("My Novel").addChapter("Chapter 1",paragraphs).
Now, lets say you want to have a word count for the entire book.
The book should ask each chapter how many words it contains.
Each chapter should ask its paragraphs, each paragraph should ask
its sentences. The total of words should ripple up and be tallied at each
stage until it reaches the book. The book can then report the total.
Only the sentence object actually counts words. The other objects just tallies the counts.
Now, where would you assign a librarian? What object(s) and functions would you provide?
If written well, the project is easily extensible.

Trying to understand the Serialization interface

Im trying to understand the Serialization of objects?
As an example, I create a Library class that implements Serializable, that stores a collection of Book objects
If I am only looking at saving a Library object to file, does the Book class require Serialization also or just the Library?
I have read the API on serialization, no answer there, if it is it's not easy to understand or read into the API...

There are some really important things to know about when doing serialization. For example one important thing to know about that not is mentioned here is that your serializable classes must define its own private static final long serialVersionUID because if you not do that will you not be able to deserialize (read in) the data you have saved later if you change anything in your serializable class. It is a bit tricky to manage files to which you have serialized different versions of your class, that is versions where you have added more serializable members to the class after you have serialized files. Well, it is not a problem if you don´t care if you have to type in all your saved data again every time you change anything instead of deserialize it (read it) from your file of course :)
Situations like this may be handled if you define your own (private) writeObject(ObjectOutputStream) and your own readObject(ObjectInputStream) methods in your serializable class but there is a better a lot smarter way to handle this. Use of a serialization proxy! how to use that is described in the excellent book Effective Java 2nd ed. With a serialzation proxy for every serializable version of your class (where a version corresponds to a version of your class with differences in its number of serializable members) may your class deserialize data written from elder versions of your class also. Actually is it first since I read the last chapter of Effective Java that I think I have myself begin to understand serialization well enough and I recommend you to do the same to learn how to use serialization in practice.

Hi. I was trying to enter the redeem field on my account.

Hi I was trying to enter the redeem field on my account. it wouldn't let me in and keeps throwing up the error message
"We could not complete your itunes store request. An unknown error occured (-1202) There was an error in the itunes store. Please try again later.
Can anybody offer some advice please?

By 'not letting me change it' you mean ? If you are getting an error message when trying to enter a new card then what does it say ?

Help! I don't understand the frame mechanics.

Hi, I've been trying to figure out how frames work in Flash. I'm new to ActionScript, so I don't know the inner workings of the language. I tried checking the API but no Frame class is listed. The closest thing was FrameLabel and that wasn't helpful. I need to know a few things:
1) How can I tell what frame I am in? If there is a class method for this, what is the exact name?
2) How does a frame advance? I have some code with no timer, only event listeners/handlers, and I've got a hacked animation working without playing clips on the time line. The displayed pictures change whenever I press a directional button to move the character. This is not really what I want to do however, because I'm switching the visibility of many different symbols and updating their position according to the original player symbol. Very inefficient. And does that mean that the frame only advances when a button is pressed? Am I even advancing the frame at all? I don't know any frame advance method.
3) How do frames work on the time line? I have all of my symbols on a single frame. I made their visibility false in my constructor because I don't want some things to show when I first load up the .swf file. When I created a second frame, everything went crazy and things began to show up. This suggests that the visibility = false was only done in the first frame? What caused the frame to change? I don't really get it.
Ideally I want to achieve a dynamically modifiable animation because the game actions are not going to be linear. The player character will be responding to controls (which will change the animation) and the AI will be responding to the player (which will also change the animation). I don't think I can do this without understanding frames, so please help me. I'm very confused! Even pointing me in the right direction as to where I can read about frame details would be cool. I've tried Adobe tutorials, support, and documentation but it was not sufficient. Is there any place where there is a very in depth explanation about frames, or would someone be so kind as to tutor me about them?
Thanks in advance.

You can find out the current frame by using the currentFrame property. There are a number of ways to change frames, where the most common would be prevFrame(), nextFrame(), play(), gotoAndPlay(), and gotoAndStop(). There are plenty of ways to make use of frames in a Flash file, from having linear animations along the timeline, to have each frame being a distinct zone of operation that contains elements having their own timelines.
One thing you may need to get a handle on are the different types of frames. There are plain frames and there are keyframes. Plain frames genrally involve a continuation of preceding frames, while keyframes mark an area of change. In your example of things going crazy when you added a second frame, I am guessing you implanted a new keyframe because had you inserted a plain frame the status of your content from frane 1 would not have been impacted.
I don't know of any resources for you to follow up with for learning more about frames--I came to learn them thru trial and error. Someone else may come along with some suggestions for reference materials.

Error while trying to expand the frame in oracle report...

Hello
I have standard report "Material Account Distribution Detail" in 11.5.10 in INV module and I want to customize the report which i want to add few more fields.
Current width and height of the"Main Section" under Layout Model is 15 and 8.5.
What I tried is i increased the width of the Main Section to 20 and I tried to run the report and it error out saying the error as "REP-1219: 'M_value_range1' has no size -- length or width is zero." I have not touch the any frame, I just tried to increase the width to see whether it works or not...
How to fix this issue and how to increase the frame size so that I can able to add few more fields...
Note: Concurrent program output print style is 'BACS'
Thanks!!!

Hi
Try to increase just by 1.. and see what causing the problem
If any page number - remove and do it again.
However try below

Hello, World - trying to understand the steps

Hello, Experts!
I am pretty new to Flash Development, so I am trying to understand how to implement the following steps using Flash environment
http://pdfdevjunkie.host.adobe.com/00_helloWorld.shtml
Step 1: Create the top level object. Use a "Module" rather than an "Application" and implement the "acrobat.collection.INavigator" interface. The INavigator interface enables the initial hand shake with the Acrobat ActionScript API. Its only member is the set host function, which your application implements. During the initialize cycle, the Acrobat ActionScript API invokes your set host function. Your set host function then initializes itself, can add event listeners, and performs other setup tasks.Your code might look something like this.
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" implements="acrobat.collection.INavigator" height="100%" width="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
Step 2: Create your user interface elements. In this example, I'm using a "DataGrid" which is overkill for a simple list but I'm going to expand on this example in the future. Also notice that I'm using "fileName" in the dataField. The "fileName" is a property of an item in the PDF Portfolio "items" collection. Later when we set the dataProvider of the DataGrid, the grid will fill with the fileNames of the files in the Portfolio.
<mx:DataGrid id="itemList" initialize="onInitialize()" width="350" rowCount="12"> <mx:columns> <mx:DataGridColumn dataField="fileName" headerText="Name"/> </mx:columns> </mx:DataGrid>
Step 3: Respond to the "initialize" event during the creation of your interface components. This is important because there is no coordination of the Flash Player's initialization of your UI components and the set host(), so these two important milestone events in your Navigator's startup phase could occur in either order. The gist of a good way to handler this race condition is to have both your INavigator.set host() implementation and your initialize() or creationComplete() handler both funnel into a common function that starts interacting with the collection only after you have a non-null host and an initialized UI. You'll see in the code samples below and in step 4, both events funnel into the "startEverything()" function. I'll duscuss that function in the 5th step.

Hello, Experts!
I am pretty new to Flash Development, so I am trying to understand how to implement the following steps using Flash environment
http://pdfdevjunkie.host.adobe.com/00_helloWorld.shtml
Step 1: Create the top level object. Use a "Module" rather than an "Application" and implement the "acrobat.collection.INavigator" interface. The INavigator interface enables the initial hand shake with the Acrobat ActionScript API. Its only member is the set host function, which your application implements. During the initialize cycle, the Acrobat ActionScript API invokes your set host function. Your set host function then initializes itself, can add event listeners, and performs other setup tasks.Your code might look something like this.
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" implements="acrobat.collection.INavigator" height="100%" width="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
Step 2: Create your user interface elements. In this example, I'm using a "DataGrid" which is overkill for a simple list but I'm going to expand on this example in the future. Also notice that I'm using "fileName" in the dataField. The "fileName" is a property of an item in the PDF Portfolio "items" collection. Later when we set the dataProvider of the DataGrid, the grid will fill with the fileNames of the files in the Portfolio.
<mx:DataGrid id="itemList" initialize="onInitialize()" width="350" rowCount="12"> <mx:columns> <mx:DataGridColumn dataField="fileName" headerText="Name"/> </mx:columns> </mx:DataGrid>

UTL_HTTP.end_of_body Exception Error. Trying to Understand the Reason Why?

I have the following PLSQL Function that returns a End_of_body Error. This started when we migrated from 10g to 11g. It is simple enough to capture so the error does not stop the Function Flow, but the error causes the OCI driver in OBIEE to error, which prevents the use of OBIEE IBOT to execute. Trying to understand why this error is occurring..not sure if we have a permissions issue on the UTL_HTTP Package or what?
Anyone seen this problem in 11g? Suggests on resolving would be great. Thanks.

Hi, thanks,
it is oracle10g,
The Exception is : ORA-29266: end-of-body reached

Trying to understand the getResource method

Hi!
I'm writing a simple game and I'm using a game framework for java. The framework uses the getResource("path") method on creating every texture. The constructor only accepts the relative path. My problem is I don't want image files to be placed in the build folder. I would like to create textures from an absolute path. I don't want to modify the framework code.
In the Class Loader javadoc I've found that getResorce method executes the findResorce method if it fails on finding the resource. The findResource method should be overriden in a Class Loader implementation. How can I do it?
Thanks.

Thanks.It does this so you can JAR your application, which gives you the ability to distribute an executable with all of your resources included. So your buds will not have to worry about if they have the support files installed to run your application or not.I understand the intention, but it's rather an opposite of what I'm trying to do. In my idea the game on it's first running aks the user for a path. The path points a place where the sounds and images should by downloaded i.e. from an ftp server. On the later runnings the game already know where the images, etc have been downloaded and uses them.

Trying to understand the B_EO_INBOUND_PARALLEL ?

Bonjour a tous et a toutes,
We have 15 integrations scenarios.
-> ¾ are Async (JMS / IDOC & IDOC / JMS)
-> ¼ are Sync (JMS / RFC to CICS and return in JMS)
We are trying to give priority to the Sync scenarios in order to avoid a timeout on the sender side.
Here are the EO parameters we are using (in DEV for now):
EO_OUTBOUND_PARALLEL = 5 B_EO_OUT_PARALLEL = 20
EO_INTBOUND_PARALLEL = 3 B_EO_IN_PARALLEL = 20
So we get (in SMQ2), 3 inbound queues and 5 outbound queues. This is working correctly.
What do not seem to behave the way it is documented are the B_EO _ parameters.
My understanding is that all in inbound messages will be equally distributed in the 3 inbound queues with a maximum of 20 messages in each and every queues, for a maximum of 60 messages being process in parallel.
Idem, for the 5 outbound queues (20 messages each = 100 messages being processes in parallel).
We are not getting this type of behaviour Instead, we get more than 3 inbound queues (and more than 5 outbound queues) with weird names
Is this because we are getting more messages than 60 inbound messages ?
Back to my initial request ... prioritize Async messages. We have used message filtering to achieve that I have 2 questions
1) De we have to set filtering for OUR ENTIRE Async message to a lower priority queue and assign ALL Sync message to a higher priority queues? Is that how we should proceed?
2) How can we make sure (when we watch SMQ2) that message that are sent to a higher priority queue are getting process BEFORE a lower priority queues ?
Any help will be greatly appreciated!!

Hi David,
First of all Many thank for your answer! It seem that there is not that much peoples that has work with parameters
I have checked the OSS note you are mentioning. We will install it and test it. It might resolved other issues we have with queues:
SMQ2 - Status: RUNNING forever? & SMQ2 - "Transaction Executing ...." for ever ...
We have some blocked queues from time to time and the batch job (that restart the message) do the job. However, in some cases the queue (we get an error in CCMS) get blocked but has the status: RUNNING (not SYSFAIL) and it stay that way for ever until we manually unblock the queue. We have a support ticket open at SAP support.
Not sure I understand the meaning of the LOCK_MESSAGE parameter. It depend of what type of SYSFAIL you get ? This is parameter is available in our instance, but not in the documentation ... Can you elaborate, please ?
In your case, we you set the values to EO_INBOUND_PARALLEL and EO_OUTBOUND_PARALLEL both to 12, and B_EO_IN_PARALLEL and B_EO_OUT_PARALLEL to 250. Do you see an even distribution of messages in each and every queues? In our case, it seem that the B_EO parameters are not working as documented. We do not see an even distribution I have even run the pgm in debug to see how it reorg (balanced) its queue
Yes, we have set the BALANCING parameter is to 1
We are on PI 7.0 SP12 HPUX with Oracle as well but in HA mode.
