Create A RTSP Video Stream On A .NET Platform
Jan 14, 2011
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.

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 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?

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 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.

Above is the response of the page I am trying to get if I enter the URL: However, the program just crashes with the following code (i.e. never even displays final - meaning stream is still going on) I think that it is streaming the video, in addition to the source- which I do not want to happen How can I retrieve this source?

I have a interesting problem: Where I work we've built a home-grown ERP system in VB6 that we are slowly moving over into vb.net. There are some projects have are in .net: we have a hand-held C# project that uses a web service to talk to our database, I've built some reporting screens using Crystal and some smaller maintenance screens.
Well as we have been plotting the conversion out, we want to have a way to separate our business logic and UI so that the UI can be a win/web form or a Smart Device project. Is this even possible? I try to reference the DLL in a test I have and it gives me this error when trying to debug using a emulator Deployment and/or registration failed with error: 0x8973190e. Error writing file '%csidl_program_files%smartdeviceproject1system.windows.forms.dll'. Error 0x80070070: There is not enough space on the disk.

Until recently I have been using net 2005 with distributing an app which uses an access database with getting data using recordsets
I decided it was time to upgrade so I got net 2010 & started using ADO.net with a dataadapter.
To my dismay I have found that my app will not run on all platforms, ie XP, Vista 32 & 64 bit, Windows 7 32 & 64 bit From another question I have been told
"If compiled to target AnyCPU, your program will fail to run in an x64 environment if it utilizes any ODBC database driver. In this case, you must compile it to x86. Therefore, x86 is safer than AnyCPU."
Which I have found to be correct I am not familiar with all the options to open a database & the respective code required to extract/change the database data. I also don't understand the implications of using x86 cpu instead of any CPU
MY net 2005 apps have been working fine for the last 6 years (until W7 64 bit), so I want to develop an app that has the same lifespan without having to make variations to the build for specific platforms
I would like the answers to the following:
1. is x86 the new standard for specifying cpu & works on all platforms?
2. why does W7 64 bit have a windows & windows x86 system folder
3. why does my installer when "any CPU" is specified install it in the x86 system folder (W7 64 bit, even though the app fails when trying to open the database as outlined above)
4. which method of opening an access database is preferred which works on all platforms with a common cpu specified?

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

i am creating a program which scans and saves images. in my program i have the option to save images and with each image i save it gets its own number for example: file1, file2, file3, file4 and so on. the only problem i have is getting the prgram to remember where it left off so it carry's on the number. my understanding is that i need to create some sort of stream writer or file stream class for this proccess to work. so it save's the last image number i was on, and carrys it on next time i open the program up again. and i also need it to re-write the new image number its on for next time. so i need to write and read the text file (.txt) and write it again if you catch my drift? i have a book to help but the wording in it is so confusing at the min, i m lost where to start.

How would one create video files in .NET? Any magical class library out there that allows you to capture images at a certain interval, then combine them into some popular video format? Any ways to capture streaming video from, say, a webcam? I have still images down pat, already made a couple different progs with that. Now looking for ideas on how to go about capturing actual video....
All that I have searched have brought be to DirectX, with DirectShow. Is there a different way? Every DirectX SDK I seem to download has everything but DirectShow (and with dialup, usually, when I say "Download" I mean, "installed it from a cd with the files downloaded by a friend on it" ).

How to Create Video Games in VB.Net
I realize that this is a very popular subject, especially amongst budding developers. The drive to create games may be the reason you started working with Visual Basic in the first place. After stepping through a few samples and getting the hang of working with user controls on a form, it may be very tempting to start to throw some PictureBoxes and a Timer on a Form and start to implement some game logic. Seems easy enough, right?
To some extent, this is a true statement.You could start to do this and it would be easy enough¦ at first. But when you begin to try to calculate collision and animate or rotate your sprites, you may start to run into some difficulty. And attempts to circumvent the problems often lead to even worse issues.This can cause an endless spiral of misery which could leave you thinking VB just isnt meant to make games!
The initial problem that most people face is the desire to use a PictureBox (or any other control) as the logical Sprite¯ container for the elements in the game. It makes sense since the control appears to provide a lot of the required functionality already and its easy to extend it with more properties as needed.
The issue though is that Windows Forms Controls are designed to be drawn statically“ that is, they arent meant to move around in real-time. You can of course move them at run-time, but this is normally an on-demand operation (something which occurs because the user just took an action like clicking a button or menu item). Attempting to move controls in real-time puts a heavy strain on your application and can cause poor performance quickly.[code]....

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?
