video-capture

In Android/Java, Is there any code example to capture the screenshot of a computer with good frames per second programatically and create video? I'd like a tutorial or full source code to do this. I'd like the program to work with and without the device having been "rooted". There is app in the play store called Screencast Video Recorder that does this. But you need to ROOT the device for it to work, so I know it can be done. What's the best way to capture android screenshot and create a video programmatically on a non-rooted device? Check the following link https://code.google.com/p/java

I am trying to figure out how to record a video using AVFoundation in Swift. I have got as far as creating a custom camera but I only figured out how to take still pictures with it and I can't figure out how to record video. From what I understand you have to use AVCaptureVideoDataOutput to get the data from the recording but I can't figure out how to start the recording and implement the delegate methods. The whole AVFoundation Programing Guide/Still and Video Media Capture is in Objective-C and I can't seem to decipher it out. Here's my attempt to accomplish this task: First I set up the

I'm trying to develop an iPhone app that will use the camera to record only the last few minutes/seconds. For example, you record some movie for 5 minutes click "save", and only the last 30s will be saved. I don't want to actually record five minutes and then chop last 30s (this wont work for me). This idea is called "Loop recording" . This results in an endless video recording, but you remember only last part. Precorder app do what I want to do. (I want use this feature in other context) I think this should be easily simulated with a Circular buffer . I started a project with AVFoundation. It

I am currently doing a project for school and desperately in need of help. The main gist of the project: I am using 3 Bosch Dinion IP Cameras to film students during a lecture. I have to create a program on Visual Studio that enables the lecturer to view all 3 cameras on one screen, able to record all 3 footages and then save them in a database afterwards. The thing about Bosch is that there is very limited material for me to refer to online. I have already referred to SDKs from Bosch and Ozeki but I can't seem to figure out the codes. I sought help from a few people and they told me to use

Thanks You could also use Expression Encoder 4 ( http://www.microsoft.com/en-us/download/confirmation.aspx?id=27870 ) to screen capture the WP8 emulator and get a nice video out of it. You can define the screen area, clipping the emulator shell if you want. Here is a couple of posts on

I'm writing a program to save some webcam video to a file. I'm using the x264 codec found here x264 When I try writing frames to a file I get this error message poping up. x264vfw [warning]: Few frames probably would be lost. Ways to fix this: x264vfw [warning]: -if you use VirtualDub or its fork than you can enable 'VirtualDub Hack' option x264vfw [warning]: -you can enable 'File' output mode x264vfw [warning]: -you can enable 'Zero Latency' option I found this VirtualDub Hack but then I'm not using virtual dub. I'm not sure what the File output mode and zero latency mean. I think the problem

Following code doesn't work. Whats wrong? AVCaptureDevice * videoDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; AVCaptureDeviceInput * videoInput = [AVCaptureDeviceInput deviceInputWithDevice:videoDevice error:nil]; AVCaptureSession * captureSession = [[AVCaptureSession alloc] init]; captureSession.sessionPreset = AVCaptureSessionPresetMedium; if (![captureSession canAddInput:videoInput]) NSLog(@"Can't add input"); [captureSession addInput:videoInput]; self.stillImageOutput = [[AVCaptureStillImageOutput alloc] init]; [self.stillImageOutput setOutputSettings:@
