Question:	Hi, I have a form that I want to add video from my webcam. How do I go about adding the ActiveX control into the form (what ActiveX control do I need, ezVIDC60.oxc?). I just want keep it very simple, to only display video automatically. If possible send or tell me the source code that will enable me to do that. You must be very busy, but I am in need of great help, anything you can do to help me will be of great. thank you for your time.... Arnaldo Alvarado

This is quite simple to do:

Download the file from here: http://www.shrinkwrapvb.com/ezvidc60.zip
Put ezVidC60.ocx into C:\WINDOWS\SYSTEM
Open Visual Basic and check 'ezVidCap Component by Ray Mercer (VB6)'.
Add the control to your form.
You should see a box with the live video being displayed in design time and runtime like this:

Comments:	This is a GREAT control. VERY easy to use. However, recently, it started being detected as spyware on several customer machines. Is there a rogue version of this control out there?

Comments:	I have used ezVidCap control on my application and found it very helpful. The only problem i get is when I capture movie it gives me a message box stating the location where the video file is. Is there a way I can get rid of the message box and start recording.

Reply:

Set the MakeUserConfirmCapture property to False to disable this message box and record straight away.

Comments:	is it possible to store the avi video of different filenames rather than only CAPTURE.AVI??? I means store video at different location and filenames....

Reply:

You need to change the CaptureFile property to the location you want to capture to.

Comments:	can i save a video in any video format rather than avi format?

Reply:

This control can only capture in AVI format. You will need to find another way of converting the AVI file into the format you want.

Comments:	I have built an app that captures AVIs and takes snapshots and saves as JPG. However, the instant that the window is minimized or loses focus, the ActiveX control stops refreshing, and therefore my snapshots are always the same. Ideas?

Reply:

The video preview does not update when none of the ezVidCap control is displayed on the screen, which is causing your problem. Unfortunately, there are no properties or methods to change this behaviour. One way around it is to make sure the Form is displayed just before the picture is captured and then hide the Form again if desired. Put two Timers on the Form as well as the ezVidCap control and try this code:

Private Sub Form_Load()
Timer1.Interval = 5000
End Sub

Private Sub Timer1_Timer()
SetFocus
If WindowState = vbMinimized Then
WindowState = vbNormal
Delay 1 'To allow enough time for the Form to be displayed
ezVidCap1.SaveDIB "C:\Pic.dib"
WindowState = vbMinimized
End If
End Sub

Sub Delay(t As Integer)
Timer2.Interval = t * 1000
Timer2.Enabled = True
Do While Timer2.Enabled
DoEvents
Loop
End Sub

Private Sub Timer2_Timer()
Timer2.Enabled = False
End Sub

Comments:	We are starting a project at my lab where we need to incorporate a still image captured by a webcam into a vb screen. So I need the program to initiate the picture and project it after it is taken at a certain spot on the form. The programmer is gone for a semester, and I've never used VB before, but my boss doesn't care how to do it as long as it gets done. If you can, please help!

Reply:

Put an Image, a Command Button and an ezVidCap control onto the Form and try this code:

Private Sub Command1_Click()
ezVidCap1.SaveDIB "C:\Pic.dib"
Image1.Picture = LoadPicture("C:\Pic.dib")
End Sub

The image from the ezVidCap control will appear in the Image control.

Hey Guys,

Please please please let me know if there's a way to select the video programmatically compression codec without having to use the dropdown.

Thank you so much,

You can capture a picture using ezVidCap and then load it into a PictureBox with this code:

ezVidCap1.SaveDIB "C:\Pictures\Capture.dib"
Picture1.Picture = LoadPicture("C:\Pictures\Capture.dib")

Reply:

To capture still images, use the .SaveDIB method. A project that shows how to capture video is included in the ezvidcap.zip download (see above). Have a look at this page, which gives a very simple example of a video capture program.

Comments:	Guys, Is there a way to release the capture card driver which is currently being used???? how can i set the ezvidcap current driver to null or some sort so that i can free the device for others to use it

Reply:

I have had a look at the control and cannot see any way of doing this except to change the Capture Source using the .ShowDlgVideoSource method.

Comments:	how can i decrease the size of the file and the size of the picture.

Reply:

Use the .ShowDlgVideoFormat method to let the user reduce the resolution of the live video. This will result in smaller pictures being captured using the .SaveDIB method.

Hi,
Your ezvidcap.ocx control seems pretty helpful. I want to be able to start up my app using the previously selected drivers. Every time I start the demo it prompts for a driver even PRIOR to the load event occuring. Is there a way to save and recall the settings to fully automate the start-up procedure. (Save settings to a file or a reg-key etc.) I can do the coding if you can tell me how to intercept the driver call! Your help would be appreciated.

Regards,

Peter

This control was made by Ray Mercer. Your problem is something that is happening with your computer and I don't think there is a way around it. I have three video sources and the control always chooses the correct source to use. Are all your video sources webcams?

Reply:

I don't think this is possible because each video source uses its own settings. You would need an ActiveX control written specifically for the video source to be able to change these settings.

Comments:	Hello, Thanks for the control. I would like to know how the captured file(earlier) can be shown(later)?

Reply:

The information on this page should help. Here is some code you could use to record a .avi file using two buttons:

Private Sub cmdRecord_Click()
ezVidCap1.CaptureFile = txtAVI.Text
ezVidCap1.CaptureVideo
End Sub

Private Sub cmdStop_Click()
ezVidCap1.CaptureEnd
End Sub
