I'm trying to play an encrypted HLS video using MediaView and MediaPlayer is throwing a "can't create player" exception. Searching for a solution all I found was this post from january last year, saying it is not supported and to add a feature request. I looked in the JDK bug system for HLS/live streaming and didn't saw anything related. Is this still not working on the latest JavaFX?
View RepliesI am trying to make an encrypted video chat program using JMF. I have successfully written the "video chat" part - which includes getting data from webcam and transmitting it using RTP, but how to get raw data video to encrypt it before it stream between the webcam and the network.
For RTP I am using RTPManager, and for reading from the webcam I am using this code:
DataSource ds;
CaptureDeviceInfo di = null;
StateHelper sh = null;System.out.println("Started Video");
String str1 = "vfw:Logitech USB Video Camera:0";
String str2 = "vfw:Microsoft WDM Image Capture (Win32):0";
String str3 = "vfw:Microsoft WDM Image Capture (Win32):0 : vfw://0";

I plan on using a stream cipher for encryption, maybe RC4.
I need to implement a URL which looks something like below one. The Notable thing is that its only one parameter i need to access and the value that's supposed to be held by the parameter is encrypted which may contains characters like & and =.
Example 1.
www.abc.com/disp?v=qww78agd=
The parameter v in above url contains value qww78agd=.
Supposing the encryption turns out the following way.
Example 2.
www.abc.com/disp?v=qww7&f=iuy68=
www.abc.com/disp?v=qww7&f==iuy68=
Then servlet will take v and f as two separate parameters, whereas i want to obatain qww7&f==iuy68= from parameter.I thought of taking up all key value pairs from request HashMap and concatenating the joints via & and =. But the problem is that two consecutive = signs as in second case of example 2, its treated as only one equal to in request key,value map. Hence, my other = sign(s) are lost.Is there any way such that i can get query string part as it is on my servlet and parse it using string processing on my own?
I have an program with an encryption and a decryption method, it works fine when i specify a name for the encrypted file, but i want the name for the encrypted file to be in cipher text, how do i do this and specify the path? i have marked out the "encryptionPath" specifically for specifying the location of the encrypted file which will have a cipher text name.
Here is my code so far

I have an encrypted MSCONS.txt file as Outlook item. I also have a Digital Certificate file (Certificate.pfx) with a password.
How I can read the actual MSCONS.txt file in my java application? Any sample code snippet ...
I've written most of the code (along with another classmate) to get this to work, but I can't seem to return the encrypted value. I'm also trying to figure out how to separate the digits (or if I'm supposed to) to make the numbers encrypted. The main kicker is that we have to be using methods to return the final values. Everything compiles, (It compiles, but no results really.)
A company wants to transmit data over the telephone, but they are concerned that their phones may be tapped. All of their data is transmitted as four-digit integers. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer number and encrypt it as follows: Replace each digit by the remainder after (the sum of that digit plus 7) is divided by 10. Then, swap the first digit with the third, and swap the second digit with the fourth. Then print the encrypted integer. Do the encryption in a method and send the encrypted number back to main.
Here are the method headers: public static int encrypt(int num) // Takes num as a parameter and returns the encrypted value public static int getnum() // gets one number from the user Example: If the user enters 1234 they should see: 0189
import java.util.Scanner; //Needed for Scanner class
public class LNFI_LNFI_program2
{
public static void main(String[] args)
{
getnum(); //Calls for getnum() method

I've been on this for a while and for some reason I just can't seem to get this to work. I know my code is solid, but it won't display my image. I've tried swithcing the image to different directories and also using different image sizes and types. I even used Orcale's guide to display your image, but still no go! All I get is a blank canvas? There are no errors. I'm also running NetbeansIDE 8 that supports JavaFX and I made sure the project is a JavaFX Application project.
All I get is a blank new window, but no images.
Here's my code:
package javafxapplication3;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;

The homework called for me to display it three times - the first one regular, second resized, and the last one rotated. I even deleted the extra images in hope at least one appears.
I'm working on a project right now in JavaFX, and got stuck. I am drawing a path consisting of CubicCurveTo's and I wonder if there's any way to get the X and Y coordinates from certain parts of that path.
Imagine following a curve (path) with a pencil slowly, and every second you take note the X and Y coordinate. I mean I'm not interested in the control points or start and end points, but the points "in between", preferably at a certain interval.
I've searched for many things online, but have trouble knowing exactly which words to search for. "Paths" often bring up file paths, traversing, coordinates etc. all fail to give me any good results.
I tried to be as specific I could, and I don't think my current code is of any interest in this matter.
(The point of it all is that the path should simulate the path a person walks, and I will store the coordinates in a database for every second).
When i press a button, i want to create a new object in my window(that i have created using scenbuilder, so i have a FXML file and a Controller class). In the window where i have a create button, there are also some textfields where you are supposed to enter name and date.
What i want to do is take the input from the TextField and store is temporally in a String variable, Its this strings i want to take the data from when i create a new object on my View. When i try to do something with the TextFields i get multiple errors that i dont understand at all.
I know my code may be very un-structured the absolute right way, i know, but i dont have time reconstructing and trying to understanding new patterns .The object is the circle and the vertical line.

I have noticed that you can style JavaFX controls using their sub-structure.
E.g. to style the label in a table column header to be left justified I can do this :
.table-view .column-header-background .label { -fx-alignment: center-left ; }
How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?
ToString()-Representation of KeyEvents. I was expecting '$' as text value, because Shift was pressed.
Unfortunately, KeyTyped is not fired in this case, so I am not able to get the information from this event.
How can I get the actually typed '$' from KeyPressed?
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_PRESSED, consumed = false, character = , text = , code = SHIFT, shiftDown]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_PRESSED, consumed = false, character = , text = 4, code = DIGIT4, shiftDown]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_RELEASED, consumed = false, character = , text = , code = SHIFT]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_RELEASED, consumed = false, character = , text = 4, code = DIGIT4]

I am new to JavaFX and OpenCV. The Problem is, that JavaFX can't handle Mat objects. First I load an image as a BufferedImage. Then i have to convert this to Mat. Do my image Processing with OpenCV and again convert the result image to a BufferedImage to display in on my UI. Here are the methods for converting Buff to Mat and Mat to Buff I found on the internet:
public static Mat img2Mat(BufferedImage image)
{
byte[] data = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
Mat mat = new Mat(image.getHeight(), image.getWidth(), CvType.CV_8UC3);
mat.put(0, 0, data);
return mat;
[Code] ....
Next I do some OpenCV stuff:
public static BufferedImage hello(BufferedImage img) {
Mat source = img2Mat(img); //Convert Buff to Mat
BufferedImage outImg = null;
try{
System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
[Code] ....
Finally I call the hello method in my controller:
void menuItemTestFired(ActionEvent event) {
try {
result = ImageProc.hallo(bImage);//bImage is an image I've loaded before.
imageView.setImage(SwingFXUtils.toFXImage(result, null));
[Code] .....
Unfortunately I get a lot of errors. Here are the first one:

I using this code to fir FlowPane into ScrollPane
FlowPane flowPane = new FlowPane(Orientation.HORIZONTAL);
ScrollPane scroll = new ScrollPane();
scroll.setContent(flowPane);
scroll.viewportBoundsProperty().addListener(new ChangeListener<Bounds>() {
@Override
public void changed(ObservableValue<? extends Bounds> ov, Bounds oldBounds, Bounds bounds) {
flowPane.setPrefWidth(bounds.getWidth());
flowPane.setPrefHeight(bounds.getHeight());
}
});
Unfortunately this maybe is not the best solution. Is there another more simple way to fit FlowPane into ScrollPane in Java 8?
I'm using WebView to display an OpenLayers3 map, e.g. Animation example from openlayers.org. When I lock my screen and unlock it, none of the openlayers layers are re-drawn. Sometimes bringing the window in to focus or a small resize of the component will cause the map to go blank. This doesn't occur in any browser I've tested, so it seems to be a WebView specific issue, although it also seems to be layer specific and possibly cache related. I've only tested on Windows, 1.7.0_51 x64 and 1.8.0_05 x64 ....

Is this right?
There are a few things lacking in the TableView's keyboard navigation handlers. In tracing the code, the behavior is handled via TableViewBehavior and its super classes. If I want to augment that behavior, how do I do it?
Ideally, I would like to subclass TableViewBehavior, but I don't see how I can do it. This gets created in the TableViewSkin ctor:
public TableViewSkin(final TableView<T> tableView) {
super(tableView, new TableViewBehavior<T>(tableView));
...
}
but as you can see there is no factory method to create the behavior class. If there was, I could subclass TableViewSkin and override the factory method.

I have an image (16x16 icon). I want to put a superscript 10 on it -- so a 10 above and to the right.
I can probably do this with a TextFlow node, but that seems very heavy for such a simple thing.
Is there some simpler way to do this?
The 10 isn't a fixed constant (so I can't just edit my image).
