How Can I do an 21 channels acquisition program on CVI?

Hi, I need support about an application
I need to acquire continuously 21 channels from a DAQ board 6224, the software must be CVI, the sampling rate must be bigger than 1KHz. I need to plot all channels in the same chart. The aplication must to run aprox 1 hour.
I think the application must be a real time aplication, I need to do digital filters before the data are going to plot
Many controls need to changed in diferent times.
I did a program, the sampling rate was 200Hz, I use a multithread aplication but I can´t increase the sampling rate, CVI give me a error after some seconds.
I use three threads, one is dedicated for acquisition, other is for data analysis (filtering and plotting is here) and the main thread is for controlling the software and the user interface.
Sombody help me??

Hi Sean,
I have already seen that example, but it didn´t work well, I did a modification it, instead to plot like in the example I created a new function for plotting my data, but when I did it I had error later a few seconds. I attach you the example with the modification.
So I think it won´t work to my application. Do you have any comments about it or some advise for me?
Thank you,

How can I see the alpha channel in the channels palette?

Hello, mi format plugin loads a rgba image. I see it with transparency, that's ok, but when I go to the channels tab I only see 4 items (RGB, Red, Green and Blue).
How can I see the alpha channel of my file in the channel tab?
Thanks!

OK, something must be wrong... but I don't find it!
That's my whole code (resumed). I ommit some code (saving file code (not used) or main function, where I only call te "DoSomething" functions. You can see that I use layers. The DoReadContinue function is only used to show the preview.
In the DoReadStart function I set the parameters for the layers (and the preview), and I fill the "data" and "layerName" params in the DoReadLayerContinue function. I hope you can understand the code!

And that's the image that I obtain loading a 8 layer image:
The layers have transparency (when I set "transparencyPlane" to -1, or 0, or 1, or 2, or 3, or 4....., I got the same result!). The blending mode is still "normal". I had set it to "linear dodge" The "isVisible" param works OK.
Alpha 1 is still black.
Is possible that I need to set something in the .r file? I had to add "FormatLayerSupport { doesSupportFormatLayers }," to manage layers, for instance.

How can I output the alpha channel in Premiere elements 10

How can I output the alpha channel in Premiere elements 10. What format should I use?
Tried outputting to an AVI filet but the file did not contain an alpha channel that After Effects 5.5 would recognize.

Bill,
I hope you ordered 32 GB or more on that new computer After Effects 5.5 takes up as much as it can.
The Roto Brush tool is really a timesaver over ordinary Rotoscoping. Although, my problem now is: when I try to send a 1 min. And 11 second video from Adobe Premier Pro 5.5 two Adobe Media encoder 5.5, the process hangs in wait state in the Media Encoder. I have filed a request for help on the Media Encoder forum.
I know you will put your new computer to use in helping other people and for this I thank you.

Hello Martino,
this script will help:

For i=1 To 10
If i < 10 then
n = CNo("speed0" & i)
Else
n = CNo("speed" & i)
End If
If n > 0 Then
If i < 10 then
ChnName(n) = "velocitiy0" & i
Else
ChnName(n) = "velocitiy" & i
End If

How can I mask a TV channel ID on a quicktime movie file?

Hi
How can I mask a TV channel ID on a quicktime movie file?
You know, in the top right of the screen it may say BBC3.
I would like to blot this out on my Quikctime movie file.
Thanks in advance
Glenn

You would need QuickTime Pro and an image editing application.
In TV terminology the onscreen display is known as a "bug" and the best you can do is make a new video track "layer" that would cover it up.
You could make a small image file (solid color) to cover the bug or a mask track that would allow some of the underlying video show through (if the bug is transparent).

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any Apple Software Update entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install using an iTunesSetup.exe (or iTunes64Setup.exe) downloaded from the Apple Website:
http://www.apple.com/itunes/download/
Does it go through properly this time?

How can I extract the two channels from a stereo track?

Hi,
I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
void Draw(byte[] x)
            Graphics g=getGraphics();
            Graphics2D g2=(Graphics2D)g;
            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
            for(int i=0; i<x.length-6; i++)
                g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
Thanks in advance.
Maurizio Di Vitto

A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

How can I manually enter MIDI channel number in Control Surface expert Value Change field?

I am creating a software interface for a multidimensional controller which can transmit many linear values at the same time. I can not use Learn mode because it always sends data from all sources, but I can split them by MIDI channels. I would like to manually enter controlling values into Control Surface expert view.
I seem to be able only to input the message, but not MIDI channel on which it is transmitted.

Stupid me, it's hex... so 80 is Note Off ch 1, 90 Note On ch 1 etc

How can i detected that the channel is closed with nio async?

using nio, I can wait accept, read data, write data asynchronously.
now i make a server program, and want to dected if a socket is closed by client, how can i do this?
thanks.

TO: ejp
In TCP the only way you can detect a dead connection is to attempt to write to it.
Eventually this will fail probably with a SocketException 'connection reset'.When should this happen? I don't seem to get any expection. The socket is registered for read only but it never gets read for reading again. The appropriate selection key indicates it is writable, but I don't have it registered for write operation.
Isn't there any other way to get around those dead sockets without trying to write at them? This would be quite an overhead, since server has to send some check_alive message periodically...

How can I use HTTP authorization in my program?

I'm writing full-featured proxy server in Java and want to require users to provide login and password and then use their login-name internally to provide different permissions, different quotas, etc... for different users. How can I do that with Java? I prefer to use standard HTTP method for this (classic pop-up login/password dialog in client browser). This is typical solution for all password-protected proxies.
This question sounds so simple... How to popup a standard dialog asking for login/password in client browser and get its values for farther processing. But I googled for the solution and found nothing. In the Internet, there is a lot of information about how I can use password-protected proxy but none about how I can write one myself with Java.
Thanks. I need at least some clues...

I'm asking exactly what I'm asking for in the title :) . Maybe I need to give an example with additional explanation?
I'm writing a proxy. It has different settings for each user so it must recognize user name and password. Of course, user want to use a browser or other program (possibly another proxy - for example Proxomitron or Privoxy to filter banners and ads) to make requests via my proxy. Browser (not my proxy) should pop-up a dialog asking for a login and password if my proxy server will require authorization. Of course not every program will pop-up a dialog: for example in case of Privoxy or Proxomitron user must provide login and password for parent proxy. In this example "parent proxy" is my proxy. Question is: how I can request HTTP authorization (by sending Proxy-Authenticate) and handle the input? Is there any standard API for that in Java?
There is big difference between standard HTTP authorization and custom pop-up dialog or custom web-interface login page. In first case user can use standard settings in his/her program/browser to provide password automatically (in this case user just need to enter his/her password once). HTTP authorization is the standard. My proxy need to handle Proxy-Authorization request-header field.
The Proxy-Authorization request-header field allows the client to identify itself (or its user) to my proxy which (should be able to) require authentication. The Proxy-Authorization field value consists of credentials containing the authentication information of the user agent for the proxy and/or realm of the resource being requested.
So more complete question would be: is there standard API or third-party API in Java for requesting Proxy-Authorization field from a client and process its values (for example: if password and login is correct then user is allowed to use the proxy; if not user will be asked for login and password again).
If someone knows proxy server (with source code in Java) which can use standard password protection this will be good answer to my question too.
Unfortunately it seems that I will need to write account-management code for my proxy myself. Oh, this isn't too hard but for C/C++ there is a lot of examples and ready-to-use pieces of code which I can use immediately. This is why I'm asking here this question: before I will write HTTP authorization class in Java from scratch I want to make sure there is no "ready-to-use piece of code". I don't want to "reinvent the wheel".
For now, I even cannot find a proxy server with Java source code with ability to use standard password protection to prevent access for non-authorized users. So I'm asking here if there is ready-to-use API (class) for doing HTTP authorization or I need to write one myself.
