I am developing an application where in I need to stream audio and video in the local area network. There is calling option from my application where users can call each other(audio call or video call) in the LAN.
View 3 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.
find a source code of using a local area network(LAN) in visual basic.net 2008?
View 1 RepliesBasically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?
I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.

Is it possible to capture all/any audio played by a PC into a system.io.stream, so that it can then be run through speech recognition (System.Speech.Recognition.SpeechRecognitionEngine)?Essentially I'm looking to pefrom speech recognition on any audio on the client PC, google seems to suggest that capturing a stream like this can be done using Microsoft.DirectX.DirectSound, however I cannot honestly determine how.
View 1 RepliesI'm using vb.net and "my.resources" to store wav audio files.I know I can play such files using:
My.Computer.Audio.Play(MyProjectName.My.Resources.Resources.resourcename, AudioPlayMode.BackgroundLoop)
However I want to use bass.net to play the file and it requires either the the file name on the file system or a stream. how do you get the data inside an audio resource into a stream?This is what I have so far:
Dim imgByteArray() As Byte
imgByteArray = CType(MyProjectName.My.Resources.ResourceManager.GetObject("resourcename"), Byte())
stream = New System.IO.MemoryStream(imgByteArray)
[code]....
I get this error on the bold line above:
Unable to cast object of type 'System.IO.UnmanagedMemoryStreamWrapper' to type 'System.Byte[]'.
1. Is there a way to cast from System.IO.UnmanagedMemoryStreamWrapper to type System.Byte?
2. What would be the best method to get the audio resource into a stream format?
I am trying to write a little synthesizer program, and as a first step I am creating .wav files opened for reading and writing using the code below called from a button click event handler. The audo plays but once, no matter how many instances of the Audio.Play method are called. I also tried closing the file and then calling the Audio.Play method on the full path name. In each case, the audio plays but once. If I click the button again, the file will be played once more. The duration for the audio is one second, so I am sure that it is only being played once every time. I do not want to loop the data. The idea is that when the user plays a new note, I update the file and replay it with the new data. Since the file is recreated every time I click the button, I guess what I *need* is working, but I am still curious why I cannot replay the content of the file.

I have a standard WMA stream, streaming in constantly via the internet. I need to write an application to stream this audio, and looks for any periods of 'silence'. When it detects silence, it runs an event.
For the purposes of this, silence is defined as three seconds of zero-level audio. The stream keeps going in a technical sense, but there is no audible noise coming through it.
However, I want the program to detect the silence while it is still in the 'buffer'. That is, the user won't hear this silence before the program detects it is there.
The audio shouldn't stop as it is analysing this silence - it needs to keep playing the audio constantly to the user.
I'm open to using whatever suitable API is out there - such as BASS, or the Windows Media extensions built into the dot net platform.
It SOUNDS simple. In aVusual Basic application, how do I made an open (or controlled thread) connection to continuausly stream the microphone to the speakers?
View 1 RepliesI'm writing a program that will allow me to send SMS and call using a GSM modem.
I'm communicate with the modem using AT commands.
I have a problem with "connect" sound from the modem to the speakers.
After installing the modem is visible in the system as two ports.
On one of them sends and receives commands.
The second is just for voice communication.
I can't redirect PC audio input/output to the modem serial port. (So I can't hear callers and vice versa)
From what I've managed to find I have to use SAPI. (ISpVoice::SetOutput)
I'm trying to use the MSVidCtl to utilize a TV tuner on VS2008, but so far only got Audio but no Video. I've seen some other discussions and some other people having the same issue, probably related to "no encoder found" from the feature list of the tuner? How to make MSVidCtl work?
View 1 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?

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 want to know if there is a way to trim and audio.For example, I load in a song that is 3mins in length. I only want 1min 10s part to 2min 30s portion of the song and then save it as, let's say a WAV file.
Is there any API that I could look into to do this?

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.
