I've just used HBONow and found that when I want to take screenshot of the movie(just like GOT),the content of the HBONow player will become black. then I know that this is the method of prevent user from share contents.
The question is,I've used MPMoviePlayerController or AVPlayerViewController to play my own contents, how can I do the same thing as HBO and prevent user from taking screenshots?
After search, I've found what they use for content protecting

I need help. Apologies if the information I provide is not sufficient. I'm sort of an all-arounder at this job and this task has been thrown at me.
I need to add a slideshow to a a webpage. I am not even sure what code I need: jQuery, CSS, or HTML.
The homepage of the website has a Nivio slider (can't access the code to this because its owned by a management company we can't afford to pay).
This is what the editing page looks like: screenshot
The website is http://evelyns-kitchen.com
I am looking to add something like the Nivio slider (if I can't actually add a Nivio slider). Smooth transition, clean, dots below photo to represent the image, left/right arrow. Let me know what other information I can provide! Thank you so much.
Use zoho reports www.reports.zoho.com where you can create reports dashboards slideshows and many more
I've stored a video to a BitmapImage and want the user to be able to replay it. However, when I run my program it treats my BitmapImage like it's empty when it's not. I've tried doing the same thing with a picture saved to a BitmapImage and any picture will appear and fill the screen like I tell it to, but videos just don't show up. Why is this?
You cant store a video in a bitmapimage. Videos should be stored in StorageFile.
Use in your dictionary:
<MediaElement x:Key="Video1" Source="ms-appx:///Assets/Videos/Video.mp4"/
and then on page:
<MediaElement Source="{StaticResource Video1}"/>
remember to start width AutoPlay="True".
I need to capture an Image from my viewer and need to do some post processing and display it back on it.
Right now am more interested in the first part of it. That is to capture Image from the viewer.
While going through the OSG I came across ScreenCaptureHandler.
But am not able to get an Image out of it.
I am still working to get it done but in case any of you have any other way of how it can be done or an Example for screencapturehandler that you can share.
To capture the rendered view into an image I use a custom osg::Camera::DrawCallback.
To capture the view at any point, set the drawCallback on the camera, force rendering, restore to a NULL callback.
Notice that the following code is part of a member function of a custom viewer (that's probably not your case):
osgViewer::View::getCamera()->setFinalDrawCallback(new ViewCaptureCallback(img));
osgViewer::Viewer::renderingTraversals();
osgViewer::View::getCamera()->setFinalDrawCallback(NULL);
The ViewCaptureCallback basically uses image->readPixels() to read from the backbuffer.
glReadBuffer( GL_BACK );
osg::GraphicsContext* gc = renderInfo.getState()->getGraphicsContext();
// Here you should process the backbuffer's size and format
image->readPixels(0, 0, gc->getTraits()->width, gc->getTraits()->height, pixelFormat, GL_UNSIGNED_BYTE);
Hope it helps
Are Content Scripts (http://code.google.com/chrome/extensions/content_scripts.html) injected into prerendered pages (document.webkitVisibilityState== 'prerender') ?
I’ve been reading https://developers.google.com/chrome/whitepapers/prerender and https://developers.google.com/chrome/whitepapers/pagevisibility, and am trying to figure out how Content Scripts work with page prerendering/prefetching.
Thanks
TheZ, tomdemuyt: I’m afraid you guys are missing the point. ‘run_at’ specifies whether the content script is injected before or after the DOM is constructed.
However, I am talking about document.webkitVisibilityState, which can be ‘prerender’ (when the page is in a background/invisible tab), ‘hidden’, or ‘visible’. Note that webkitVisibilityState can transition from ‘prerender’ to ‘hidden’ or ‘visible’, or back and forth between ‘hidden’ and ‘visible’, without any changes being made to the DOM. (In order to better understand this, read the articles linked in my original post.)
I think I’ve been able to determine that content scripts ARE injected into prerendered pages. Here’s the problem, however: let’s say my content script does something that should not occur on a prerendered page. For instance, it does pageview count, or adds animation, neither of which should begin until the user is actually viewing the page. So it seems that my content script should do something like what’s shown in the code examples on https://developers.google.com/chrome/whitepapers/pagevisibility - check document.webkitVisibilityState, and also listen to the ‘webkitvisibilitychange’ event, and only do pageview count/start the animation when document.webkitVisibilityState is, or has transitioned to, ‘visible’.
I may have just answered my own question, but I just wanted to make sure that I was on the right track.
Thanks
As TheZ mentioned, you should ues the run_at setting.

I am writing an iPhone app, where the user should be able to choose, an in-app background picture from his own photo album.
I am trying to enable this feature using a UIImagePickerController.
At this point I get the the box asking me to choose a picture and I save the picture.
But after that, when I want to use the image chosen as background, with this kind of code (which is the same as how I set the default background at start):
UIColor *backGrndPict=[[UIColor alloc] initWithPatternImage:
[UIImage imageNamed:pngPath]];
self.view.backgroundColor=backGrndPict;
Nothing works. I just get a white background.
Thanks for any tip.
Michel,
Just for clarification, are you saving the picture that the user selects as a .png file or in an UIImage?
If you did use the UIImage method, try double checking the retain count of the UIImage. Again, it may not be as simple as this, but that is what I did with my app and was getting the exact same issue.
If you did save it as a .png file, did you do an error check? Also, I have the "Applications" folder for my iOS simulator loaded on the screen perchance I have to verify both the availability and the integrity of the file in question.
Also, I tend to slip on the path sometimes too. I have have messed up the path one too many times by forgetting to use the saved path (the file that my app saved, almost always under the documents folder) vs. the default bundle path for the app which is where the bundled images are saved.
Hope it helps.
