I have been working on capturing image and recording video in VB using webcam. From the cource code,I have successfully captured and saved images, however for the video part I have failed to save it in any selected directory. I've checked the code with some other sample codes in internet. Couldn't see any problem or differences. My code for recording and saving are as follow:
Recording:
SendMessage(hWnd, WM_CAP_SEQUENCE, 0, 0)
Saving:
Dim save As Integer
save = MsgBox("Do you want to save your recording video", MsgBoxStyle.YesNo + MsgBoxStyle.Information, "Recording Video")
If (save = MsgBoxResult.Yes) Then

I am using webcam and want to record video and save it on disk, the video time must be constant for such 20 or 30 sec, what i want is to change CAPTUREPARMS members which contain fLimitEnabled & wTimeLimit
'---capcaptureget function
Function capCaptureGetSetup(ByVal hWnd As Integer, ByVal s As Long, ByVal wSize As Integer)
capCaptureGetSetup = SendMessage(hWnd, WM_CAP_SET_SEQUENCE_SETUP, wSize, s)
End Function

how to develop video webcam recording application.
I'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 3 RepliesI need a hint or sample source code is much better for my project. Here is the idea, I am creating a simple program that can record a video using a webcam as a surveillance camera. I need to record it continuous and every hour the capturde video will store/save to my drive. I am not that good in webcam/camera manipulation in vb.net.
View 1 RepliesI have a little Logitech USB Webcam that I have attached to a laptop and I want to be able to view a video stream from it. I already gathered it will need to be a client/server model...and I probably need to use TCP/IP and/or Winsock (if its still even used)...
how to really approach this application as far as the video capture process? I don't have a need to really record video in any way so if i can just "preview" the video thats fine, although recording would be a neat bonus.
I read into the Windows Image Aquisition libraries and they seemed to be the right thing...but I wasn't so sure about the cross-network half of the equation.
I'm using a picturebox to display the video captured from my webcam. I tried out two codes:
1) [URL]
The code in this forum by kaymaf. it does not work at all! there is no video displayed at all. Also, i'm currently using a PixeLINK 1394 Camera to get the video, but this is not shown in the list of cameras. It shows : Microsoft WDM image Capture (Win 32). Are these the same?
2) [URL]
This code works the first time i run it. But the second time it gives me a listbox of camera to choose from and then does not display any video. The screenshot is as displayed:
I am interested in streaming video from a webcam on one PC to another PC. Could this be done without streaming to a server. Could this be achieved by streaming using P2P?

is it possible to use avicap32 to capture video with a web cam and save the video as a wmv format instead of avi one
View 1 RepliesI have downloaded a program which is used to capture an image via the webcam on my laptop. That works fine. I added the required code to record and save the recorded video to an .avi file. The record function appears to be working fine. When I click on the Stop Record button the save file dialog appears and I enter in a file name to save the recorded video. But the message WM_CAP_FILE_SAVEAS does not appear to work as no file ever gets created in the location I choose (desktop).

I 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?
Visual 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
