I want to stream video from a simple webcam over LAN for object detection purpose. Is it a good idea to grab frames and send them continuously over network with NetworkStream.Write()?
I did this but usually on client side i lost half of image data and I got noise, I don't know what is wrong. I'm looking for a fix or a better idea.
I put the client and server source codes here, first run the client and click "START LISTENING" then run server and click "Send pic".

I 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 ?

I have an application that sends Bytes of data through UDP, these bytes are read from an AVI file when the client receives the bytes it builds the AVI file on another computer perfectly but I want to be able to use the received bytes to play the video from the stream. Does anyone know how I can play the video from a stream? I tried using DirectShow but I don't know how to use a stream as video let alone having AVI files play with DirectShow.
My main goal is to have the application slowly "buffer" the movie for the client as they watch.
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 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 12 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.
There is an IP web camera that I wrote a .NET class for sometime ago. It's basically a Timer implementation that pings a snapshot CGI script from the camera every five seconds. The camera itself is very rudamentary; it does not have any sort of API for me to work with, the only thing I can do programmatically (remotely) is invoke this script. The script returns a 640x480 JPEG image. Simple.
Now what I need to be able to do is take a days worth of these images, and create a "time lapse" AVI video stream out of it that will eventually be embedded into a web page. How can I do this with VB.NET?
I want to create a RTSP/h264 video stream from static images, and incorporate it into my .NET application. So far I have found two possible ways to do this:
Use ffmpeg/ffserver, but I would need to compile ffserver on windows and then rely on it... and I don't necessarily want to rely on an external application
Use the LIVE555 [URL] library, but they do not have any .NET libraries, so I would need to spend some effort to make it work with the rest of my .NET application.
Can you comment on either #1, #2, or which is better. Is there a faster way to bring up a RTSP server in .NET? I do not mind putting in development time if there is a solid solution that takes time, but it would be good to have something we can work with fast, for prototyping and demos.

I have been stuffing about with IO.Stream and Net.httpxxx but haven't managed to get the elements to line up in the right way.
I get "the given path's format is not supported" from opening the page in the standard stream, because it's not in the local file system ... that bit i understand, the bit I don't get is ... how do I achieve the equivelent of:

I like to make an console application to measure the time it takes to fully load a web page, what's the best approach to do that? The purpose of this small app is to monitor some pages in a website, in a predetermined interval, in order to be able to know beforehand if something is going wrong with the webserver or the database server. It would be nice to be able to measure the time it takes to fully load the the page (images, css, javascript, etc). I have some code but I is not measuring the fully page.
Dim sw As New System.Diagnostics.Stopwatch
Dim req As System.Net.HttpWebRequest = CType(HttpWebRequest.Create("[URL]"), HttpWebRequest)
sw.Start()
Dim res As System.Net.HttpWebResponse = CType(req.GetResponse(), HttpWebResponse)
sw.Stop()
Dim timeToLoad As TimeSpan = sw.Elapsed

I don't know VB very well, but I need to create a wrapper program for any executable that logs the arguments, all input, output and err information:
My wrapper is called: e.g. someApp.exe arg1 arg2
Logs to someApp.log: arg1 arg2
Calls original executable: _someApp.exe arg1 arg2
Must log and forward any console input to _someApp process inputstream
Must log any output and error stream from _someApp process
I'm stuck at point 4 now:
Dim p As New ProcessStartInfo
p.FileName = execute
p.Arguments = Command()
p.UseShellExecute = False
p.CreateNoWindow =

After _someApp ends I am able to read out and err stream to log it, but I still need to provide my own wrappers input to the process and I want to read out and err stream as it happens.

Now it seems to work fine, but I'm working with very large files (70+ GB) across a network (local copy is not an option) and while the function is executing if the user moves the application the screen can go blank and they can panic.

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):

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.
