View 1 RepliesI am using the avicap32.dll to capture images and videos from the webcam. but for some reason the code refuses to save the video files. I searched already on DIC and google and I found some topics on it, but I don't find the answer for my question
View 2 RepliesVisual Basic has a function that allows a video from a webcam to be saved as .AVI file which inherently is too large for data transfer over the internet. I would like to know if there is a function that allows the video to be saved as a .WMV, or a .FLV file so its smaller and allowed to be transfered over the net. Here is a snippet of the code i am using

How to capture a streaming video via .net and save it off to a file on the server? I have seen a few comercial applications (url...) that do it via a client app, but none of them had an API that I could interact with in .NET.
View 6 RepliesDoes anyone know how to capture (Record) the Windows desktop and save it as a '.avi' or '.mpg' file. This functionality can be done using screen capture / presentation programs like SnagIT:[URL]..I have found many examples showing how to capture from a webcam using the 'avicap32.dll' DLL file but these dont help with this problem.
If you are asking why i dont just use SnagIT its because the interface is overly complex and building my own version would allow me to intergrate it into my existing programs.
when i record a video with avicap32 all become unresponsive what is the best way to procede?
how do u force avicap32 to record on a separated thread
I have a web cam connected through USB,I capturing and saving video it with avicap32.dll and user32.dll.But in the same time I need to starting other hardware and working with it trough COM port during capturing. And here appearing a problem, because then I send a command for start video capturing:
SendMessage(hWnd, WM_CAP_SEQUENCE, 0, 0) ' start video capture
the executing code stops at this line until I click to stop to capture. But in the capturing time I need to work with my hardware, to obtain the data from it, and after that to stop capturing.To make to work simultaneous video capturing and my hardware or its impossible to do that with avicap32.dll and user32.dll.

View 2 RepliesI have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---
[Code] .....
The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.
I've been trying to play with DirectShow but it's getting on top of me and my question on here didn't answered so I'm thinking maybe I should go with a different approach. (DirectShow VB.net can't change recording format). <- Where as that 'works' I can't get it in the format I want it, and I don't really understand it so I'd obviousl like to go down the route of something I can get my head around.
I've googled till my fingers are raw trying to come up with an easy way to record video in my vb.net application, it doesn't have to be fancy, just a preview with a start record, stop record button, that's it.

View 8 RepliesI'm currently working on a project which is basically Server-Client based. Client is standalone VB executable file and Server is web based.The program is supposed to use webcam as video capture device, stream video footages to server (on website - live feed) and allows users to manually save captured videos into their computer.Thats basically the brief description of my system. I'm starting off working with VB right now and website after I'm done with VB.I'm new to VB, this would be my 1st project on it. I've looked for available sources online and found several VB apps which lets me capture image file through my webcam. Also on MSDN forum, i found recommendations on using "DCAM Server" to stream videos on website but I'm still not sure of how to configure the settings to make it work properly, and of course, don't have a proper website for it to work with yet atm. Also realise I'll need to integrate some .dll files or activeX functions to use video capture function. I don't really know how to use these yet rite now.

View 1 RepliesVB and programming on Windows as such. Mostly c++/gcc/linux. I am trying to build this VB app that shows a streaming video from a camera and that needs to be overlaid with some custom graphics and text. I used the code published here: [URL] to get the capture part to work. It essentially uses the avicap32.dll that most of you would probably know.
My plan:
1) Capture frames using SendMessage(windowHandle, WM_CAP_EDIT_COPY, 0, 0) and then copy from clipboard.
2) Do whatever graphics/text overlay on the obtained bitmap
3) send it to some picturebox on some form that is being shown
4) Do step 1 to 3 in a loop by a spawned worker thread.
Firstly is this a reasonable way to do what I want? or is there a much more efficient/easier way to about?
Now the specific problem: From my main thread directly if I do step 1 to 3 once UIComponent.DrawImage(VideoComponent.GetBitmap()) It shows me once captured image as it should and all is good.
Just to clarify: UIComponent is an object/instance that launches the Form and owns the picturebox I want to display on. VideoComponent is an object/instance that has started the videocapture and owns the picturebox to which the video is being captured. But if I wrap the same call above in a function and launch a thread that would start with that function as its starting point, I see a blank screen. Again, for testing purpose, I am only doing step 1 through 3 just once.
The thread part of the code is like this:
Private drawthread As Thread
public sub main()
drawthread = New Thread(AddressOf threadfunc)
[CODE]........
when i am recording video my application disappears.
its VB application.
FormBorderStyle : none (is it problem?)
Public Class Form1
Dim resim As New System.Drawing.Point
Dim X, Y As Integer

I am planning to create a proprietary Windows application that will let the user capture video and audio from any other Windows application and stream it onto another computer via Internet. Capturing video is easy, I could simply let the user browse all open windows (or applications) and have the user click the prefered one. But what about audio? Is it possible in Windows to capture the audio from any application?
