View 2 RepliesI want to write a .NET application to show and save video streams from an ip camera. But I'm not yet sure what would be the best way to get started. Should I look for an Axis camera so I'd be able to use their api or will I be fine accessing the video stream using directshow or whatnot using any other camera ?

View 2 RepliesI have a firewire and a camera. I can see the video as in a preview using tools like MS Movie maker.I want to write a simple program that allows a Preview and when a button is clicked, grabs the snapshot bmp,jpg.I have written a program that works with a webcam and a usb interface. It uses capCreateCaptureWindowA
But this technique displays a blank screen when trying to capture a WDM device. So i am back to square one. There must be a snippet of code out there somewhere to do this.

View 1 RepliesAudioVideoPlayback works really .FromFile with jpg or mpg files. But I am trying to show a viewo stream from a video camera over the network. The camera feed is something like ... IP-ADDRESS/mjpg/video.cgi. AudioVideoPlayback .FromUrl seems to access the camera ( the camera then prompts for log on credentials) but it will not display the feed. My question is can AudioVideoPlayback display cgi files? My all is written in Visual Basic 2008, running on Win 7/64 and x86 based platforms as well.
View 1 RepliesI've been searching for hours tonight searching existing posts, other websites and all i can find are examples of how to capture a image from a webcam.Does anyone have any code that simple talks to the camera device via WIA, and then saves every image found on the device to a hard drive?I found this code below. Credit i cant tell you as i have a bunch of different flavors of code, but this only saves the file as a tmp file, and not the actual image file i expected after selecting?

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.
capture picture or video from usb cam?
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)

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

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

View 2 RepliesI 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?
