In my project I am capturing frames using a camera. The frame resolution is 1280*1024. Now I wanted to copy the same captured frame i.e contents of buffer(1280*1024 size) into an another buffer which is of size 1024*1024. The remaining 256bits I just want to discard.
View 3 RepliesNow i'm capturing frames from webcam and send them via UDP, it's not realtime. Is it streaming?
View 4 RepliesI do this in my code, capturing a frame from camera, opening a UDP connection, and sending frame data:
UDP_Client.Connect(Host, Port)
Dim sendBytes As Byte() = Data
UDP_Client.Send(sendBytes, sendBytes.Length)
I do it every 400 ms.Is it streaming video?
I did some research (mainly in the Drawing namespace) about animated GIF files and I know you can see how many frames are in the specified GIF using the GetFrameCount method, however how I can access each frame directly/loop through them one by one. This is my first time trying anything like this and I can't seem to find the right methods, classes or information. I'm not even sure if this is possible using the .NET framework.

View 6 RepliesIn VB 2008 - Is there a way to capture the value a splitter is set to? Here's the scenario - 2 panels side by side. Panel 1 has a splitter - Split1 houses a tree view and Split 2 houses documents in the tree. Is it possible when a user resizes that splitter to grab the value and set as a default? Also, I am only able to get the splitter to be 50/50 no matter the real estate it's consuming... is there a way to preset that size and shrink the outer panel within an event so panel 2 can consume that realestate?
View 6 RepliesBasically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically. The timer is working fine and I have tested this.

This is so admin can be alarmed about security breaches etc.

View 2 RepliesI 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. My problem is that due to the computers processing power or the size of each screenshot and its quality it sometimes takes longer than 100 Milliseconds to create one causing the whole video to be off balance. How can I ensure 100% that 10 Images will be stored?
View 1 RepliesI am using frames for my web application.Description

I'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.

View 2 RepliesWhat 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.
I 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 want to take 30 frames a second from a screen (of my choice, I allow multiple screens) and the audio from the computer (stereo) set, save it to a hard disks. How do I do that? 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).
