How to pre-check for HDCP (Output Protection) capabilities of a device

[ Background ]
Your application may want to pre-check if a device is HDCP compliant ahead of time to determine if you want to stream HD bitrates to it.
One way to do this would be to package your content with a DRM policy that sets the Digital Output Protection constraint to REQUIRED. During playback of that content, if there is a DRMErrorEvent 3338 (Unknown Connector Type) or 3342 (Digital output does not have supported capabilities), then your application can abort playback and request a lower bitrate stream that does not contain DigitalOutputProtection=REQUIRED.
However, this workflow is not a seamless user experience, because playback must end and restart. It would be better to pre-check whether a device has HDCP capability before requesting the appropriate content to stream.
[ Solution - Embed & load an "HDCP checking video" into your app ]
I have created an FLV content that is small enough to embed into your application and loaded/played in order to determine if the device returns a DRMErrorEvent 3338/3342 (no HDCP detected) or a DRMStatusEvent (HDCP detected & engaged).
I have attached the same FLV as well as sample code on how to embed/load/play this content. I have also included an HLS sample, if you are an Adobe Primetime licensee. I haven't provided a code sample for HLS, but the concept is the same - embed and load the m3u8. The .ts file is not required.

Hi zeroxx,
It sounds like you are trying to do the same thing that is in one of the shipping examples. Take a look at the example named "Voltage - On Demand Output" Under Hardware Input and Output >> DAQmx >> Analog Output. To get to the example finder you can select Help >> Find Examples... If that specific one does not fit your need try looking at the other examples in Analog Output to see if any of them works for you.
Hope that helps

Pre-checks for cluster services setup

Hi Expert,
During the pre-checks for cluster services setup, I have got this error for Checking node connectivity.. How can I resolve this problem. The error is as follow as I enter "runcluvfy.sh stage -pre crsinst -n db-a,db-b" command. If the Check node connectivity fail, can I proceed to install the clusterware?

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..

How can I check for the existence of an XML file in Illustrator Javascript??

I'm writing a Javascript to run at startup. I want to check for the existence of XML files and process them, if they are available. How can I check for their existence?

Your first line just sets a variable to a string value… getFiles() is a method of Folder… so
var InputXMLDir = Folder( "D:/Brackets/Create_Bracket_Graphics/Input/XML-n-Templates/" );
Not a PC user so I can't remember if the colon is OK…? As you appear to know the file name why bother with a folder get files anyhow you could just check if the file exists then do some thing…
alert( File( "D:/Brackets/Create_Bracket_Graphics/Input/XML-n-Templates/brackets_men_web.xml" ).exists );

Carriage return in textarea - how do I check for and remove it???

I have an html form that has a <textarea> element for user input. I work mainly with Java and some JavaScript. Since carriage returns are permitted in a <textarea> element, upon retrieving the value submitted, my Java and/or JavaScript variables contain carriage returns as well, making the values incomplete.
For Example :
String dataSubmitted = request.getParameter("formInput");
<script language="JavaScript">
var textValue = "<%=dataSubmitted%>";
....//do other stuff
</script>When I view the source of my JSP page, the above statement of code looks like this:
var textValue = "This is some text that
I submitted with a carriage return";I'm putting the text submitted through this form into a mysql database, and when I pull up the values I find that it has recorded the carriage return as well. There is an actual symbol representing a carriage return in the db field.
What I'd like to do is use some Java code to go through each character of the String and find and remove the carriage return, perhaps replacing it with an empty space instead. But how do I check for a carriage return in a String variable?
Also, is there a way to use JavaScript to alert the user when the carriage return button is pressed when they're in the <textarea>?
Any input is appreciated,
Thank You,
-Love2Java

What I'd like to do is use some Java code to go through
each character of the String and find and remove the
carriage return, perhaps replacing it with an empty
space instead. But how do I check for a carriage return
in a String variable?The carriage return is represented by the \r. Generally there is also a newline, the \n. You can use String#replaceAll() to replace occurences of them by a space.
string = string.replaceAll("\r\n", " ");
Also, is there a way to use JavaScript to alert the user
when the carriage return button is pressed when they're
in the <textarea>?You can capture keys using the 'onkeypress' attribute. The keyCode of a the return key is 13. So simply catch that:<textarea onkeypress="if (event.keyCode == 13) alert('You pressed the return button.'); return false;"></textarea>The return false prohibits the linebreak being inserted. If you remove that, then it will be inserted anyway.

In both node oracle user & group should be same but in your case looks different.
Once again check your user & group.

How do I check for peripheral compatibility, ie HP DesignJet 755CM?

How do I check for peripheral compatibility, ie HP DesignJet 755CM? other older Mac computers?
Thanks.

Usually the best way is by contacting the manufacturer of the peripheral. Manufacturers have the best information for compatibility with other devices for their products.

How to Design Report for Excel output?

Hello Experts...
I have both versions Crystal Report XI and Crystal 2013 at this time as we are in the process of Upgrading...
How to design for excel output with no page size limit.
I have several fields going across (crossing width of paper size 11X17 landscape) and I do not need this report output to be printed at all only for excel output.
Appreciate your time!
Thank you,
Padma

Hi Padma,
You would need to increase the Page Size horizontally. Go to File > Page Setup > Check 'No Printer' > Check 'Dissociate Formatting Page Size and Printer page Size' > Increase the Horizontal value.

HT1752 how can I check for SpyBots and other invasion things on my computer

I am beginning to have odd things happen to my computer. Someone told me to check for SpyBots, but I don't know how. I participate on Blog Talk Radio, and was informed they use these spybot things. How do I find out if there are invasive things like this affecting my computer?
In the last 2 days I've had two windows pop up saying I needed to restart the computer. This has never happened before. Any help anyone?

Forget about the advise on the spybots. That person doesn't have the foggiest idea what is going on.
You are having kernel panics. The most likely casue for kernel panics is hardware problems usually RAM that has gone bad.
Go to http://thexlab.com/faqs/kernelpanics.html for a good procedure on how to find out what is causing the kernel panics.

Can I exit from paintComponent? ...or... how can I check for invalid data?

I'm writing a calendar applet for a programming class and I've nearly completed it but I'm stuck at checking for valid data.
What seems to be happening is that paintComponent() is being called before actionPerformed.
In actionPerformed (when they click the button), it checks to make sure they entered a valid month (1 to 12). If the didn't it dispalys a message, but if they did it calls repaint().
But even if repaint() isn't called, Java still seems to call it before actionPerformed and I get exceptions.
So I tried checking inside of paintComponent() by using a simple if(...) return; but that doesn't seem to do anything... it just keeps going through with the method.
So -- Once the user presses my button I want to make sure the data is valid before repainting the screen. How can I do this?

I validate it in actionPerformed which is called by
the action listener... that is what you meant right?
The problem is that it seems paintComponent() is being
called before I can validate the data with
actionPerformed(). I need to stop paintComponent()
from always being calledMVC. (Model, View, Controller)
Initially the internal value of the data (the model) should be valid (or null with a check in the paintComponent method)
paintComponent (the view part) shows the state of the valid data.
You press the button.
actionPerformed is called (the controller).
It checks the value and, if valid, writes it to the data (model), then updates the view.
At no point will the view have to render invalid data, because the model is only updated after actionPerformed checks the value.
The pattern may be applied with different classes performing the three roles, or different methods in the same class (sometimes it's easier that way for simple cases).

How can I check for directory creation?

Hi,
I want to check whether I can create a directory at a particular location.
Let's say at c:\windows, can create a directory called c:\windows\mydir. But I won't be knowing the parent location (i.e., c:\windows here) at compile time.
And I would also like to check for creating a directory like c:\windows\mydir1\mydir2 (mydir1 may not even exist).
What I was doing was, I created the file object for my new directory (i.e., mydir here) and used the canWrite() method on the parent directory. But this method worked only when the parent directory existed. But how can check for a directory path like c:\windows\mydir1\mydir2 where I have to create both mydir1 for mydir2.
Is there any other methods that I can use to perform this kind of a check.
Thank you

I finally figured out a workaround, but i don't know whether this is a good way of checking. :)
import java.io.File;
public class TryMKDIRs {
     public static void main(String[] args) {
          File file = new File("c:\\mydir1\\mydir2\\mydir3");
          boolean canICreateDir = false;
          if(false == (canICreateDir = file.canWrite())) {
               System.out.println(file.getAbsoluteFile() + " cannot be created.");
               File fileparent = file.getParentFile();
               while(fileparent != null && (canICreateDir = fileparent.canWrite()) == false) {
                    System.out.println(fileparent.getAbsoluteFile() + " cannot be created.");
                    fileparent = fileparent.getParentFile();
          if(canICreateDir) {
               file.mkdirs();
               System.out.println("Directory can be created. . .");
}

How can I check for 'undefined'?

Hi,
I am creating a custom MP3 player where audio playback is
started by clicking on the title of the audio, but I also want to
be able to start play abck from the Play/Pause button. In order to
implement this dual approach, I am thinking of checking if a sound
has been loaded (with 'mySound.loadSound("path to sound") already
by the my titleButton.
I am thinking of doing this by checking the
'mySound.position' as that would be 'undefined' if there was no
sound loaded.
But how can I check it for being 'undefined', what woud be
the syntax? Itexpects a number so I tried -1, but that didn't work.
Or is there a better way?
Thx,
Nik
have a Play/Pause button and for it in order to

Found the answer.
The code is of course:
etc. //
if (mySound.position == undefined) {
// etc.
I had a erroe else where.
