Capturing video frames as images using AVFoundation - objective-c

I have a running video in my application. When I press the record button, I need to start recording the running video from the point at which I pressed record button. Then the recorded video has to be saved as another video file.
Can anybody suggest me the best solution to implement this feature. The basic idea is that I need to implement the recording feature similar to Talking Tom application.
Please give me some suggestions. Thanks in advance.

Create VB program to watch a website in Internet Explorer

Thanks for taking the time to assist me.
At work we use a 3rd party online chat system using internet explorer. Basically what happens is we initially follow a link, login, a pop up window comes up with the chat control page where we would see a notification for a new chat
The issue we have is no sound plays, and it's very easy to miss a chat.
In theory could I easily learn in VB how to watch that specific window of Internet Explorer for a change, then play a sound when a change in that window occurs until acknowledged?

Save screenshots on tvOS

The question is very simple, but i haven't found an answer.
How can i take a screenshot on tvOS?
In simulator is straightforward, just File -> Save Screenshot, but on a real device?
I already tried some combination of buttons, but nothing happened.
Let me know. Thank you.
With the Apple TV connected to your development machine via USB.
Steps
In XCode from the menu Window -> Devices
Select the Apple TV on the left representing your device.
On the device, configure the screen the way you want to capture it.
Click the Take Screenshot button.
It will save the screenshot to your development Mac
The new screenshot appears on the desktop.

Detect screen capture in vb.net

Is there a way to detect screen capture or recording is processing.
Atleast a way to know the process behind screen capturing?
i guess something has to be done with Kernal side of the system but not sure.
Thanks in advance..
You could look at using something like Deviare. I haven't used it personally, but it does let you hook some of the win32 APIs including GDI32, which is probably what you would have to use.
You could capture a [print scrn] button press from the keyboard, but there are so many different ways to record video and capture screens, you couldn't possibly create a solution to scan all the different types of applications that can capture this information.

aurioTouch not playing back

I just downloaded and tried this one on the iPad. The mic is working since I can see the graphics displayed in response to voices. But there was no playback from the speaker. Yes, I have tried both mute button on and off. Any hint as to what happened?
I seem to remember there is some problem with pass-thru in that application, when I looked at it a few months back.
Try removing the DC filter.
I think it is a horrible piece of code, so forgive me for not digging into it.
I can't remember if it is just a simulator bug or whether it also hits the device.

Record Silverlight 4 MediaElement content

At the moment I'm working on a project. Which contains streaming from an IP camera to the Silverlight 4 MediaElement. The stream that goes through the MediaElement, needs to be cut when a button is clicked.
So is it possible to record MediaElement's content on demand? When that's done, write the recorded part of MediaElement to disk.
If it is possible, what's the most efficient way to do this?
Thank you in advance,
AFAIK, extract part of the entirely video, you can just use a program which has record screen function to record silverlight video on demand. Then you just play the video and use it to start recording from desired beginning and finish recording at intended ending. Thus you will get demand content.
