I have to develop an application where I have to stream my webcam over lan. I have a server where my webcam will be connected and when requested I have to send my webcam over lan. i need to view the server webcam from another network pc.
View 4 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 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?
View 4 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 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. 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 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?
in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing
[code]....
How can I write the resulted stream to be sure I can read it again later?
Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.
I have a problem with the cryptostream, if i write the stream to a memorystream the memory that the stream used is still alocated and i have no way of unalocating it.what am i missingdoing wrong? im using-using on the streams,readers and crypto stuffs so the framework should shut them all down right? i tryed calling .close and .dispose but nothing ,in fact i moved it all over I have provided the sub that im using for the encrytion im in .net 4.5 so there is a lil async stuff but i know thats not the problem coz i moved this code out of my main app(.net 4) for testing to see if i could fix the problem.[code...]

View 1 RepliesI use VS2008 with Visual Basic and VB.Net. I am writing an application to save videos from a webcam, and I've found several examples that provide the basic functionality, so that I can now start and stop the webcam, and save a video as a .avi file. However my interface is still clunky: when video capture starts following
SendMessage(hWnd, WM_CAP_SEQUENCE, 0, 0)
then the window is locked and the [Stop Capture] button doesn't function, so I need to exit the window to stop capture.The documentation at Video Capture [URL] has a lot of methods that look useful, and I think that I need to link up a callback function to allow [Stop Capture] to function, but I can't figure out from this documentation how to send a WM_CAP_SET_CALLBACK_VIDEOSTREAM message to do this. I don't know how to control the formats so that I generate video files that are concise enough for web use - changing the frame rate or dimensions seems to have absolutely no effect Is there any general tutorial that will cover all of the messages in AVICAP32.dll, and show me how to implement them in VB?
How can I have my VB.net application take a picture of me from my webcam? Nothing too complicated,
View 2 RepliesI'm trying to take a picture from my webcam when the user clicks a button on a Form on a Windows XP Machine.
I tried going through several threads, but couldn't find the solution I was looking for. Most of the threads involved matters (and code) too complex for my requirements, or had bugs when I reproduced the code in my editor window which I was unable to resolve due to my lack of knowledge in I/O related programming.
So far the simplest solution I could find was this one:[URl]...but after using his solution in my editor, it says 'type WIA is not defined', despite adding a reference to Microsoft Windows Image Acquisition 1.01 Type Library.

View 1 RepliesI wrote some software that use the AVICAP32.dll to do a spot of video capture.All was going well till they went and bought a laptop with a built in webcam.Now my software picks one a random and uses that for the video (somewhat annoying to say the least) Can anyone tell me how to pick a camera to use,I suspect it is related to DVM_DIALOG but my experiments have not been too successful.

View 4 RepliesI would like to acquire the images of a webcam in the background based on an event.I know there is a possibility to display the webcam stream directly in a picturebox but I want to process every single image and display them then.
The best would be if there is an event that triggers every time a webcam images is received. That event should include the image (in some kind of format).
I need to show video in a picturebox, and when a button is pressed, capture the frame. I am making a desktop qr reader. I have the qr reader completed and working. my issue is my camera now. I would prefer something that actually works, and doesn't have severe memory leak issues, and doesn't throw an exception after it's first or second use. Would AviCap32 or Direct Show be better for what I want? Which would capture the image fastest, without causing exceptions? I tried using an open source solution called webcam_capture.dll, and it worked at first, but now I am getting an exception that I dont know how to fix. I'm assuming this goes in vbGeneral, and not the Interop and Upgrade. Most examples I have seen, use interop, so I wasn't sure. I would prefer not to use WIA. I have attempted it, and it doesn't work quite right on my computer, and this application will be distributed.
