I am having a problem with the JavaFX MediaPlayer playing videos with resolutions greater than 1920x1080px. For testing purpose I downloaded the example from [URL] ... and added the following error-handling:
The video is encoded with h264 and aac (for audio) and is having a resolution of 1920x1168px. The error occurs with each video with a resolution greater than 1920x1080px. Vidoes with a resolution of 1920x1080px or smalle are working fine. The playback of all videos is working with VLC-Player. I tried Java 7_51 and Java 8_5.
I am currently making a video player which allows users to open/play videos which are stored on their computer. I am using JavaFX for this.My problem, is that sometimes when I click the button to load a video, a java.util.ConcurrentModificationException is raised. Other times, it's perfectly fine.I put the calls to .loadAndPlayMediaA() and .prepareMedia() (see below) inside a .runLater(Runnable) to try to prevent this, but it has not worked. My Code (below) is called by a listener on a button, "testButton". I have a class called JfxMediaPlayer which holds the method loadAndPlayMediaA(), and a class called MixingDeck which holds the method prepareMedia()
I am working on a UI in JavaFX and create several instances of a custom control class. The control consists of a Pane which wraps several other containers, one of which contains a Circle shape.
At one point, I instance this control and access the Circle shape directly. I transform it's center coordinates (which are always {0.0, 0.0} ) to Scene coordinates. The problem is, the transformation always yields coordinates that correspond to the upper left corner of the control's root pane.
In other words, it's as if the Circle is positioned at the upper left corner of the custom control (when, in fact, it's positioned near the lower right corner).
I have other instanced controls already in the scene, and they do not have this issue - converting the Circle's coordinates to scene coordinates works as it should.
It seems obvious that I'm accessing the Circle too soon - that perhaps the scene graph hasn't been fully traversed for the control and the Circle's position within the control's hierarchy hasn't been updated. I've verified that my attempt to access the Circle's center coordinates occurs after the control's initialize() method is executed, so how to ensure the control's scene graph has been fully updated before I try to manipulate the control...
While doing trial and error got caught in the below scenario.
public class Crypt { public static void main (String args[]) { /*all I want is calculate a binary number (ex -: 22 , 34) using decimal base (10n). *So, I have to convert 2 p into 10n form so I have to find n in terms of p . We have x as the input. * The formula works as below. *2p =10n *p ln (2) =n ln (10) *n = p [ln(2) / ln(10)] *2 p = 10 p [ln(2) / ln(10)]
So today i was trying to compile a simple script that used to work before on Sublime Text 2, an i got the following error;
javac: invalid flag: Usage: javac <options> <source files> use -help for a list of possible options
I already know the script works because i didn't change anything since the last time it work, but anyways just in case i tried running a HelloWorld program just to check it out and i got the same error. The i stop trying to compiling the HelloWorld on Sublime so I went to Terminal and i got the same exact error.
I get this error when I load a HTML page with WebEngine. The HTML is getting generated by an own (Java-)ServerSocket. How can I figure out where the problem is? I can load the HTML file successfully when loading the(same) generated HTML file from the local filesystem. Maybe the http headers causing these problems ? On the other hand I can load the page without problems in Firefox. How to get more information ?
I have uninstalled JAVA because I needed to download the 64-bit version but no matter WHAT I do I still get the same installation error message "keyset as registered in invalid" and I was downloading it from [URL] .... I will do whatever it takes to fix this!

I am using the Netbeans IDE for Java creations. What are the steps of creating a media player using Java thru Netbeans as i don't understand most of the jargon and the forms,classes,etc.I don't want to use JavaFx but plain Java Application.I am coming from a Delphi pascal background.
my program is working for mp3 files but for video file it shows error "player not found".i wanna know that how it is possible if my JMFStudio is able to play videos directly
I'd like to draw an overlay on an image. The overlay is also an image with a black background and a white foreground. Now the white pixels should be drawn on the image in red. This is possible with the code I posted below. However, the problem arises when rotating the stencil (overlay). I get some interpolation errors from the rotation on the boundaries. I tried to clip them with setClip(), but this turns the background from transparent to white. How to remove those spots? Or maybe a completely other idea of achieving an overlay on the image? I'm aware of the pixelreader and iterating through the stencils pixels and draw the respective pixels as rectangles on a Canvas' graphicContext. However, this was extremely slow, compared to the code I posted below (although it doesn't work with rotations).

I'm trying to establish an SSL connection (using a self-signed certificate). However, I can't seem to get the handshake to work. At the moment server side, I've created the public/private key + signed certificate and then stored them in a KeyStore. I've also stored this signed certificate in a KeyStore (trustStore) client side, so it can compare.
import java.util.Scanner; public class Magic { public static void main ( String args[] ) { Scanner in = new Scanner (System.in); int[][] square = new int [4][4]; int sqlength = square.length; int magicValue = sqlength * (sqlength * sqlength + 1) / 2;
[Code] ....
Here is what the output should look like.

I have now slowly moving on the learning Database Connectivity.Found a simple example on one site and tried to execute it, Creating a database, connecting to it and displaying the output.
I am getting trouble with recordset in displaying all the records in the badabase. It displays the very first record correctly but if I try to enclose it in while(rs.next()) loop, it generates an error message saying "Invalid operation at current cursor position".
