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
I 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.
currently, im using a webcam in my thesis. one of my objective is to have a realtime camera that can record/capture a video at the same time can capture image. i dont know how to code it in vb.net.
I have managed to record my webcam which saves to the desired location and is displaying to the screen while recording but i am trying to run other functions while the webcam video is being recorded but the rest of my form stops functioning until the recording is completed.
Is it possible to record and continue other functions at the same time
I am building an application in vb 2010 that uses wmp ocx to play videos from remote streaming servers. Is there a way to record or save that video simultaniously? Which technique should I use? I have searched a lot on this but unable to find solution yet. Do i need to use Directshow library?
I creat audio video chat and when calling receivng video and client video is together...I want that client move his or her webcam video where want...as I know it name DROP&DRAP but I`m not know how to do it...
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.
I 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?

I'm new to VB, this would be my 1st project on it. I need help and guidance on how to start please, especially on video capturing functions.I've looked for available sources online and found several VB apps which lets me capture image file through my webcam.

I have problem in recording video from webcam the video file not always appear in its specific path in the running time in addition there is so much delay to appear. 5 sec is the time of the video duration, I want to save the video when it start to load but in the same time it save the video show the video in the background which I have problem in this point too.
I 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).
'Start recording Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click DeviceID = lstDevices.SelectedIndex OpenPreviewWindow() SendMessage(hHwnd, WM_CAP_SEQUENCE, 0, 0) [Code] .....
I'm a computer science student and I have a project to do where I need to have VB connected to a webcam to take captures of items and then save them according to the item name that stores them into either a dbase or access database. I have knowledge of oledb using vb to retrieve and modify access databse so it might be better to head in that direction, but I have no clue how to get the webcam talking to vb and see the live feed from the cam until you take a picture and save.
How do I force users to save the current record (if current record has changed) and not let user go to the next record unless the save button is pressed?
I have a program that reads and displays a file as an annimation and I want the user to be able to turn it into and AVI (or other video format). I certainly know there are Screen Capture programs that will captured the video from the screen, but I have seen an app that creates the video in the background. The user selects the file, and without sending anything to the screen it creates the video.
how this done or where to start? Or if there is an addon app that will do this?
This code i had use for create a field in DB Access 2003:
SQL = "ALTER TABLE plano_contas ADD declperiodica06A char(40) WITH COMPRESSION NULL)" Dim command1 As New OleDb.OleDbCommand(SQL, con1) con1.Open() command1.ExecuteNonQuery() con1.Close()
like you see the code create a Text field with 40 lenght...Well the problem is:When i save a new record the record it's save in this mode: "100......... .........................." - the points means spaces and should be:"100"After try a lot of things i'm without more solutions in find why this happen!
I 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
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?
