I need to get a synthetic generated video stream in a program like skype. The audio part is easy. There is a project called Soundflower which is an adapter. It presents a virtual audio destination device on the one side and a video source on the other side. I am searching for the same solution for OSX. Except I only need the part how to present it as a virtual camera. Do not misunderstood, I do no
TL;DR: Don't like reading? Jump straight to the sample projects on GitHub: iOS 8 Sample Project - Requires iOS 8 iOS 7 Sample Project - Works on iOS 7+ Conceptual Description The first 2 steps below are applicable regardless of which iOS versions you are developing for. 1. Set Up & Add Constraints In your UITableViewCell subclass, add constraints so that the subviews of the cell have their edges p
I am animating a CALayer along a CGPath (QuadCurve) quite nicely in iOS. But I'd like to use a more interesting easing function than the few provided by Apple (EaseIn/EaseOut etc). For instance, a bounce or elastic function. These things are possible to do with MediaTimingFunction (bezier): But I'd like to create timing functions that are more complex. Problem is that media timing seems to require
After serval hours' digging in the Contact App, I have figured out how it works. ABNewPersonViewControlle invoke some class in ToneLibrary framework to do this. The call stack looks like this: 0 CoreFoundation 0x3359a1d4 CFGetTypeID + 0 1 CoreFoundation 0x33596396 __CFPropertyListIsValidAux + 46 2 CoreFoundation 0x33517090 CFPropertyListCreateData + 124 3 AudioToolbox 0x38ac255a AudioServicesPlayS
As of iOS 5.0, there is now a faster way to grab data from OpenGL ES. It isn't readily apparent, but it turns out that the texture cache support added in iOS 5.0 doesn't just work for fast upload of camera frames to OpenGL ES, but it can be used in reverse to get quick access to the raw pixels within an OpenGL ES texture. You can take advantage of this to grab the pixels for an OpenGL ES rendering
I currently build all my applications with hudson using xcodebuild followed by a xcrun without any problems I've received a couple of IPA files from different people that I would like to re-sign with a enterprise account instead of the corporate account (for the app store, or sometimes ad-hoc distributed). My problem is that when I try to resign the app, it won't install on my device (and it shoul
Very similar to this question, I am trying to convert a project that uses ASIHTTPRequest & ASIFormDataRequest to ARC. In my view controller classes, I often refer to and use properties of the request object in the completion blocks (looking at the response code, response data etc): __block ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:SOME_URL]]; [request se
There's no way to set the vertical-align on a UILabel, but you can get the same effect by changing the label's frame. I've made my labels orange so you can see clearly what's happening. Here's the quick and easy way to do this: [myLabel sizeToFit]; If you have a label with longer text that will make more than one line, set numberOfLines to 0 (zero here means an unlimited number of lines). myLabel.
I have implemented an overlay view when calling camera view before recording the video. pickerController.cameraOverlayView =myOverlay; Video recording and saving the video into Album after recording the video and sharing via email etc. all works fine. If i use video quality as "High quality", then the recorded video has become huge size. For example, if i record video for 30 seconds with high qual
