May 28, 2007I would really like to get some VB.net program code for still image capturing using a Webcam.I've searched the web for quite a while now but did not get any codes. Currently i have a code for capturing video. In that code an image can be captured, but only with 640 X 480 resolution (Maximum Video resolution for my web camera). The WM_CAP_DLG_VIDEOFORMAT dialog box only allows the resolution to be set up to 640 X 480.

Mar 28, 2012I have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?

Sep 30, 2011I have a screencasting program where it takes 10 screenshots every second and saves it to a temporary directory then through ffmpeg the series of images are compiled into a video format.

How can I ensure 100% that 10 Images will be stored?

VS 2010 Animated GIF Frames?
Sep 10, 2011I've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.

VS 2010 Frames Per Second In Picturebox Repaint
May 31, 2012I'm looking for a way to limit Picturebox repaints. For example, I wish to be able to only call "repaint" a certain amount of times per second. All my searchs have come up with nothing. I could start a timer and get it to call repaint manually but that only ends up calling it more as it doesn't stop the normal form raising the event.

View 2 RepliesShow An Image For Exactly # Synchronized Monitor Frames?
Jun 9, 2011What I can do: Display an image (e.g. a bitmap) by loading it into a control (e.g. picture box), showing that picture box (visible equals true / refresh) and then hiding it (visible equals false / refresh).The onset of the image onto the screen is not necessarily synchronized with the raster scan (needs to run on CRT monitor) meaning the lower portion of the image may appear one (partial) frame before the upper portion. Though I can specify (roughly) how long the image is on the screen I cannot specify the number of frames and there is enough variability in the timing that I will not get the same number of frames every time.
What I'd like to do: I'd like to be able to have my display wait until the beginning of the next frame before showing my image. I'd also like to tell it exactly how many frames to show the image before removing it. Ideally I'd like to be able to cue up multiple images to be shown for one frame each in order (animation).
I've found a lot of information on the web about DirectX but the few tutorials I've tried are overly complicated for my needs and invariably fail to start for unspecified reasons.I don't need 3D.What I want to display would work just fine in a picture box if the timing were cleaner and predictable.
Stream Contents Of A WPF Form (as Frames) To An AVI File?
Apr 15, 2011I currently send a live video mix to a output screen (a form on a particular screen).Consider it like a really advanced version of PowerPoint. I call it a video control room for the pc.

I know I can draw the image of the interface using the RenderTargetBitmap class, but How do I put those images (as frames) in an AVI file or push it to a video server? An SDK? or a Code Example to point me in the right direction, would be nice! I also want to capture the sound of the current Stereo mix, or microphone (as determined by the user).
