Nevermind, figured it out. However, I ran into another problem. The avi capture session does not like the latest version of Divx on the compression.

Without knowing what type of card do you have and what output format do you have, it is hard to know what the problem is. Normally ffdshow works good on MPEG4 video and you can get a free download of ffdshow decoder.

What are some of your favorite "generic" (i.e. non-NI) DAQ instruments? DIO, AIO, etc.

I like Ontrak, for reasons I can't really explain other than comfort level, and Measurement Computing, which most of you have probably heard of.

Hello Richard,

Take a look at HYTEK iUSBDAQ. There are two models of iUSBDAQs, they have the best performance/price ratio. Besides the newest model iUSBDAQ - U1208LOG is unique that combines three features into one DAQ (PC control mode up to 64ksamples/s, standalone data logger mode to USB flash disk directly and build in video functions) that you don't find others on the market, plus still low price. Check it out:

http://www.hytekautomation.com/Products/IUSBDAQLog.html''>http://www.hytekautomation.com/Products/IUSBDAQLog.html' target="_blank">http://www.hytekautomation.com/Products/IUSBDAQLog.html

It can be used in sport industry (like golf, baseball), car racing industry, bio feedback, physical therapy, weighing system etc.

Irene

One more thing I have to mention about iUSBDAQ is the light and easy to use library, you don't have to install a huge file for drivers, this will make end product easy to maintain.

I hope I can make it to LAVA/OpenG BBQ, because I am still stuck in Buffalo right now. Missed the flight today due to the US boarder crossing delay... Now I have to buy a new ticket, too bad. I will miss Tuesday's sessions for sure , just hope tomorrow's flights will be straightforward, no more troubles, delay, then I will hopefully make to BBQ. But if I arrive late tomorrow to miss the BBQ, I will still have my gifts with me. So you guys can still count on my gifts, just deliver later.

Which way of life is more happier, more positive, more efficient?

Is living as if it would die tomorrow or living as if it would never die?

Or

Is living with conscious more happier or living with less conscious more happier?

It's very very hard to beleave that this still applies to DirectX 10

Tomi

Sometimes you just have to take it even it's very hard to believe.

That said, if there is really anything you want to do in dot net for webcam, you have to do it in C++.net which then is unmanaged code, then you have to wrap up for C# or VB.net to be used in managed directx...

Hello,

Please try out IVision LabVIEW toolkit:

http://www.hytekautomation.com/Products/IVision.html

It contains not only video acquisition, video mixing functions, as well as image processing functions. You can ask question in IVision forum if you get any.

http://forum.hytekautomation.com

If you just want video recording, display without processing it, then you may also check out iUSBDAQ - U1208LOG, this is a USB data acquisition module with video functions, you get both fast speed USB DAQ plus video plus logger , here is the link:

http://www.hytekautomation.com/Products/IUSBDAQLog.html

should be available soon.

Irene

QUOTE(Tomi Maila @ Jun 4 2007, 07:44 AM)

If you are using Windows you should also be able to use Microsoft DirectX library .NET interface that provides API for webcam connectivity. LabVIEW allows you to interface any .NET API using .NET nodes.

Managed directX (directX for dot net) has very limited support for directshow, there are some functions in .net for supporting avi playback, I doubt it has even support for webcam at all in .net and I read somewhere that Microsoft is not going to do so for a reason that it's hard to do it in .net.

Irene

Thank you Mike, it does have something wrong with the original link. I copy one more here:

hmm, I have to turn off HTML mode, otherwise it always has some extra thing in the url link, not sure how to make a url link in LAVA.

Thanks,

QUOTE(proja @ May 20 2007, 07:49 AM)

ok, im new in labview. I have some problems dealing with pixmaps and images and i would be GREATFULL if someone could show me some tricks. I am using labview 6.1 for one project and i am having problems selecting certain pixels from one image [256*256]. The problem is - i dont know how to do it. I think i could make an array out of the image [pixels would be elements of that array, right?] but i dont know what information that array stores or how to see and process the information about one pixel's color.. What is the best way to do it? PLEASE help me, i have to finish this project ASAP!

thanks in advance

You said you can get array out of the image, do you get three arrays representing R,G,B color, or all in one array? I assume you get three arrays, since you said each one is 256x256. This is a 2D array, the row index and column index will position the pixel, the value of the array is the grey scale. So if you handle the gray image only, then you just need to index the array with LabVIEW index array function to get one gray value. If you handle color image and have three 256x256 arrays, then index each array and combine the three gray scale into one color value with RGB to Color.vi. Make sure the order of R,G,B, otherwise you will not see correct color.

Couple years ago, I remembered that the roast beef meat at Salt Lick was pretty good, I ate at least 2 or 3 pieces which was too much usually and I enjoyed very much seeing Jim counting the $20s he gathered and Michael said "Finally OpenG get paid off", I had a very good laugh, I was wondering why this photo was not published, it was so fun :laugh:

I am thinking if I will go, we will see.

Here's a strange one.

I recieved a mailing from NI; "Events in your Area". It indicated that there are upcoming user group meetings in both Toronto and Kitchener/Waterloo Ontario on May 29th. But when I went looking for the details that were supposed to be located at ni.com/seminars I found that neither event was listed.

I realize these won't be Lava Group meetings. As far as I know those haven't happened around here since Michael moved to the left coast. But it would still be nice to hook-up again with local LV programmers and users.

Did anyone else receive this information? Does anyone know any details?

Hopefully there actually is a UG meeting this month.

Feels pretty cold seeing no reply as if no one in Toronto region doing LabVIEW .

Anyway I remembered I did receive similar email a while ago, but I checked my schedule, not able to go and also not sure how to say "hello" to people that I don't know, so I am not going .

As usuaul I have a new problem:

I can't work out how to get the frame rate from a media file. Is this possible?

thanks for all the help so far,

Bernard

Sure it's possible. Use IVision_MediaSetTimeFormat.vi and IVision_MediaGetDuration.vi, you can get total frame numbers and as well as total time period for an avi file. Then you can calculate the frame rate.

Irene

QUOTE(superslug @ Mar 14 2007, 07:58 PM)

Is it possible to combine a bmp with an avi frame by frame so a different bmp could be included into each frame?

Having done that can a new avi be made with the bmp in each frame?

Yes, it's possible by using the callback vi, you can catch each video frame passing by and do image processing on it (like combine a bmp). There are examples in IVision labVIEW toolkit to show how to use callback vi.

I like MadTV too, those guys are very sharp and thorough and funny and "racist". Watched many times, most time I wanted to see what silly and stupid things that Bobby Lee would say and do that make his race looks bad.

By the way, does Apple reserve all product's name starting with a "i"? I also need few of these names too...

QUOTE(Aristos Queue @ Mar 7 2007, 01:25 PM)

I think using ReInit to Default is completely the correct solution for a user interface component. Using it for changing values of variables that are actually part of your program is really bad form (it means you're using variables that can be accessed outside the dataflow and all the problems therein that have been discussed to death elsewhere). As a UI component, it's very useful for a "reset to inital state", such as a Clear button for some output, or a Reset To Defaults button on an Options dialog.

My opinion.

I know losing data flow is a bad thing for programming style, that I understand. Always pull data out from a wire (a very thick wire), not from middle of nowhere I was thinking if the property node has some inefficiency by itself.

Irene

QUOTE(Michael_Aivaliotis @ Mar 7 2007, 02:04 AM)

In general, using the reinitialize to default node is considered bad form.

How much bad is using reinitialize to default node?

I just felt sometime it's hard to do things just because it may not be the best way to do. And how much differences would it make to use not the finest and most efficient way?

It's like my husband told me that garage door opener has life cycles (how many times can we open it)? It kind of puts some psycho on me that I somtimes open only half way of the garage door for saving the life cycle.
