How can I get a hardware-based screen capture?
In the past, some of my projects have required me to create a movie version of a fullscreen Flash application. The easiest way to do this has been to get a screen capture. However, capturing anything over 1024x768 has resulted in choppy video, which is unacceptable. I understand that there are hardware based solutions for capturing fulls...
What is the best method to capture images from a live video device for use by a Java-based application?
I am looking into an image processing problem for semi-real time detection of certain scenarios. My goal is to have the live video arrive as Motion JPEG frames in my Java code somehow. I am familiar with the Java Media Framework and, sadly, I think we can consider that an effectively dead API. I am also familiar with Axis boxes and,...
Capturing video out of an OpenGL window in Windows
I am supposed to provide my users a really simple way of capturing video clips out of my OpenGL application's main window. I am thinking of adding buttons and/or keyboard shortcuts for starting and stopping the capture; when starting, I could ask for a filename and other options, if any. It has to run in Windows (XP/Vista), but I also wo...
Resources for working with video feeds in C#
I'm starting to get into a side project that I hope to pull in frames from several small IP cameras, perhaps do a bit of motion detection and redisplay them in a form with alerts. Does anyone have some good resources or similar projects that I could use to get acquainted with the ins and outs? I'm using C# 3.5 with SP1 in VS2008 ...
How can I intercept video or image streams from a webcam and modify them?
Is there a generic API call I can make to get a handle of the image or video feed coming from a webcam and replace it with an image or video of my own so that applications interfacing to the cam (e.g. MSN/Skype/Yahoo IM) will see my image instead of what the camera is capturing? Ideally, I am trying to solve this in a generic way indepe...
Most efficient way to move an image from a C program to Java and shown on the screen?
Background I am capturing video using the video4linux 2 spec. It is captured using a C program in real-time. I also have a Java frontend that can run both locally and remotely. The remote side was easy, I just compress the images to JPEG and ship them over a mini-http server to the client that decompresses them and shows them on the ...
Setting Zoom on Windows Mobile device with IAMCameraControl::Set()
Hi, I am developing an application for video capture and I would like to implement zoom functionality. Working with DirectShow I came across IAMCameraControlInterface. It has a method ::Set(), which should be used for setting several camera parameters. However I played around and I couldn't do anything with it. Then I tried to call ::...
Options for predictable frame capture in .NET application
I am working in C# and have the need to capture individual frames of video files. As quickly as possible (faster than real-time), I wish to seek to a specific frame number and capture every nth frame to a graphic file format such as BMP or JPEG. It is highly desired that the frame that is captured be predictable and repeatable, i.e. do...
Record Video of Screen using .NET technologies
Is there a way to record the screen, either desktop or window, using .NET technologies. My goal is something free. I like the idea of small, low cpu usage, and simple, but would consider other options if they created a better final product. In a nutshell, I know how to take a screenshot in C#, but how would I record the screen, or area...

What is the best practice for storing and processing images and videos?
My application (written in WPF/C#) will monitor a live video source and will need to store small video segments and image stills. I'm hesitant to use a user defined "temp" directory since this would potentially allow a user to modify or delete these files causing major issues with my application. Alternatively, I have attempted to store ...

I am just in the process of making some little demo tutorial videos for my app to help users get up to speed. I have used Camtasia in the past but don't really like it.

Alternatives to DirectShow for video capture on Windows
I am looking at updating a program that currently uses DirectShow for video capture. While DirectShow seems to work well, I was wondering if there were any more powerful or up to date SDKs or APIs that I should look into. Some features that would be helpful would be ones that will: Provide a consistent framerate (33ms between frames ...
Video capture SDKs and Frameworks for Windows
I cannot find a list describing all of the different options for video capture in Windows. I would like to keep this list to non-proprietary SDKs (i.e. ImageSource has their own SDK that works with only ImageSource capture cards). To set an age limit on suggestions, everything should be able to run on Windows XP or newer. Include as mu...
Which video and audio format/codec should I use?
Environment: Windows XP/Vista, VS2008, C#/.NET 2.0, VideoGrabber. Hi All, I'm writing an app which captures cameras input and encodes them into a movie file (including sound). My client suggests I encode the movie using the DivX codec. But it's not installed by default and it's not redistributable: Users would have to download, instal...
Can Flex/Flash Record the Screen?
This question is pretty straight forward, I literally just want to stream video of a user's computer. Just like recording from a webcam, but with the source coming from the desktop (think "screencasting tool".) I specifically want to do this in pure Flash, no downloads or add-ons. This would be an easy question for Google, but it is co...
