Webcam continuous capture and save to avi later

Hello,
I am new to LabVIEW. If anyone could help with the USB webcam and LabVIEW 2010. I have all the IMAQ drivers installed.
What I am try to do is capture video continuously into a buffer memory or an array and be able to extract that buffer video and save it as an AVI video.
So the main question is buffering video in memory and write as an avi file in later time.
Sorry if this confusing. Please let me know, I can be more details to clear thing up.
Thank you so much for all your help.
Dan

Hello Rory,
Queue is an array with first in first out mechanism which allow you to keep the images in the memory. To create queue, you would need to use Obtain Queue function with string name and image data type as input, the result is that you have a queue to put your image into. During each acquisition loop, you would need to create a new IMAQ image before enqueueing so that each images has it's own memory space.
Attached is an example that you can try to see as an example, in addition, LabVIEW example finder also have many queue examples.
Hope that this help you started.

HT1296 How can I capture and save an image on my screen for later retrieval

How can I capture and save an image on my iPad screen for later retrieval, perhaps on my Laptop (Windows 7)?
Is there a way to copy the image to a storage device?
Thanks, Don.

Its easy to take an iPad screenshot. Press & release the Home and the Power buttons quickly at the same time. I have trouble with that so I press & hold the Home button and then very quickly press and release the Power button. Your screenshot is stored in the Camera Roll of the Photos app. Probably the easiest way to get it to your PC is to be using iCloud, or email it to your PC. There are also some wireless sync apps in the iTunes app store that let you send photos from the iPad to a Mac or PC. I use PhotoSync.

APP-PAY-07546: Before continuing, enter and save new information...........

I logged into oracle applications (enter and maintain > query person > other > qualifications) and entered a new qualification. Then i saved the newly captured qualification and exit oracle applications. When i log back into oracle applications again to see the qualification i just captured, then i get this following error message: 'APP-PAY-07546: Before continuing, enter and save new information, or save the information already entered.'
What causes this error message to display? I did save the record first time I entered it. The error message will not go away until i save the record again. Then only can i continue.

Hi,
Please go through (Note: 295314.1 - How to Troubleshoot APP-PAY-07546 Errors) and see if it helps.

just because i haven't stop the DataSink before close it..
who can tell me why?

Spectrum Analyzer GPIB Record and Save to AVI, MPEG, or MP4 file

My objective is to record a waveform using labview and save it as an AVI, MPEG, or MP4 file to be able to replay it back at a later time.
I would like to know if it is possible to capture a waveform for 30 to 60 second and save it as an movie format file.
I have Labview 2013 version, Spectrum Analyzer N9010A and GPIB-USB-HS.

Start by looking for the LabVIEW driver for your instrument. There may be something in there for capturing your waveform.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Capture and Save SQL Command that Ran in OLEDB Data Source

Hi,
My company is using SSIS to occasionally generate a file that is then being loaded into a transactional system. At this point, things are not fully automated; the SQL query that is used for the data source is manually altered, SSIS is run, and the
file is uploaded to the other system. Every time the SSIS package runs, a log entry is created with summary information.
I'm wondering: is it possible to capture the SQL command that runs in the data source, and save it with the log entry as part of the package run? This would provide an accurate historical record of what filters were applied to the data that was loaded
to the transactional system.
Any thoughts/comments would be appreciated.

Hello Smith,
What I understood from your question that you want to know the query which is running in SSIS Data Source and same you want to insert into a table.
Below query gives you what all queries are currently running on a specified DB:
USE [SAMPLE_DB_NAME]
SELECT distinct getdate(), command, s.text, start_time, percent_complete, CAST(((DATEDIFF(s, start_time, GetDate())) / 3600) AS int) AS Long, CAST((DATEDIFF(s, start_time, GetDate()) % 3600) / 60 AS int) as LongMin, CAST(((DATEDIFF(s,
start_time, GetDate())) / 3600) AS varchar) + ' hour(s), ' + CAST((DATEDIFF(s, start_time, GetDate()) % 3600) / 60 AS varchar) + 'min, ' + CAST((DATEDIFF(s,
start_time, GetDate()) % 60) AS varchar) + ' sec' AS running_time, CAST((estimated_completion_time / 3600000) AS varchar)
+ ' hour(s), ' + CAST((estimated_completion_time % 3600000) / 60000 AS varchar) + 'min, ' + CAST((estimated_completion_time % 60000)
/ 1000 AS varchar) + ' sec' AS est_time_to_go, dateadd(second, estimated_completion_time / 1000, getdate()) AS est_completion_time, blocking_session_id, r.status, last_wait_type,
r.open_transaction_count, r.session_id, client_net_address,
CONVERT(VARCHAR(20), sp.host_name) as hostname,
CASE WHEN program_name = '.Net SqlClient Data Provider ' THEN 'Reporting Service'
ELSE CONVERT(VARCHAR(50), program_name)
END as program_name,
sp.login_name as name
FROM sys.dm_exec_requests r CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) s INNER JOIN
sys.sysusers u ON r.user_id = u.uid
INNER JOIN sys.dm_exec_connections dec ON dec.session_id = r.session_id INNER JOIN SYS.dm_exec_sessions sp on r.session_id = sp.session_id
WHERE text not like 'SELECT getdate(), command, s.text, start_time, percent_complete%'
AND text not like '%sys.sp_trace_getdata%'
AND text != 'sp_server_diagnostics'
ORDER BY start_time
You can schedule this query to run in 2-3 second and can capture the T-SQL and insert into a table.

How do I download an app from the Mac App Store but not install it and save to do later?

I'm getting the free Lion download for new Macs from the Mac App Store, but am not ready to install it yet. It appears that apps (including Lion?) from the App Store automatically install themselves. Is there any way to save an App Store download (.dmg?) for later installation without having it automatically install? I asked Apple Support via chat, and they said it could be installed later but couldn't tell me how.

The Lion download is different than small apps. What you get with Lion is an installer. But be sure to make an extra copy because after using the installer it deletes itself.

How do you acquire multiple image buffers and save to disk later?

Good morning everyone,
I am working with the LabVIEW code posted below. I am taking images through a CCD camera at a high frequency. Therefore, I need this code to be able to keep up with the trigger. I take anywhere from 30 to a few 100 images and acquire them through buffers. The code I have now (which I got from someone else in my lab; I did not write it) saves the images in the for loop in which each is required. This slows down the code considerably. Timing is important to my application. Does anyone know if there is a way to set each buffer aside after they are acquired and then save them to disk AFTER all the images are acquired. I think this will allow the code to keep up with the trigger.
As a side question, I would like to have the code trigger my camera on both the rising and falling edge of the trigger pulse. As you can see from the code, I tried to set this up, but the method I tried doesn't work; each time a new trigger is setup it wipes out the old one. Is there a way to set up 2 triggers?
Thank you very much,
Matt

Left from the loop there's an "Array Subset" vi because I didn't use the first two pictures of the ring.
So you can forget about it and wire the ring directly to the "For Loop".
You can see the Ring as an array of images, so basically you don't need any VI to retrieve an image from the ring, just an "Index array" will do.
Wire the output of the "Index array" to an image control.
This is of course if you first fill the ring and then process it.
If you want live images, then you can use the vi you're using to extract an image from the buffer but I understood that you want to acquire images as fast as possible and process them afterwards.
Correct? Yes, then you don't need the "IMAQ Extract Buffer" vi.
And yes, you can remove everything from the loop, just check if the number of frames is reached.
When all frames are acquired, quit the loop and process the ring buffer.
I checked your code again, and observed that you do nothing with the ring buffer
You build it up in the first For loop and delete it at the end of the code but never used it in the loop
I attach a larger view of the acquisition loop, so that you can have a better idea of the whole ring stuff.
I have a shift register for the ring so that all states can access it.
The state "Save all images" loops through the array, to save the images one by one.
I'm sorry I can't post the complete vi, it's way too large and contains lots of sub vi's to analyse the images and handle the I/O toward the process line.

Do I need to convert my 12-bit camera to 8bits to "grab and save an .avi file? If so, HOW?

i am using a 12-bit camera with imaq-vision software, the latest version, along with labveiw 7.0. I narrowed the error down to the ACI write frame icon. It is giving me an error that the image type is not correct. leaving the error image is not compatible error #1074396077. Any help would be greatly appreciated

Some cameras offer the option of 8 bit output, or you might be able to do it in MAX. If not, you will need to convert each image from 16 bit to 8 bit using a 4 bit shift and IMAQ Cast Image. Wire the 16 bit image as the source and an 8 bit image as the destination. Wire the output image to the AVI Write vi.

Why do I get data rate too high error after capture and save? (using AJA Kona)

I record(capture) about an 70 min program with Adobe premiere CS5 once a week. About a year ago I got the error *data rate too high" when stopping "capture" when saving program to Video HD(2TB). The video recorded was OK but after about 15 min the audio was out of sync and garbled. I thought I had found the problem by defragging the video drive. I have not had any problems for about 50 weeks.. until this week-it happened again. I know the video drive(2TB) was defragged and only half full. I was able to recover the program since I back up the program on a DVD but had to go through a lot of problems massaging it since I send the program to a local ABC broadcast station in 16/9 SD and the DVD is rescored in 4/3 .
I have the CS5 program on a separate 2.5 GB drive. I am running Win7pro and have a RAID series of Intel Xeon ES410 processors.
Any help as to why I get this "Data Rate too High" when saving program would be appreciated.
Thanks much!

I have three Mitsubishi broadcast quality cameras (two HD -waiting on money for switcher and 3rd HDcamera). They feed to their camera control untints and then to a switcher and then into video computer and the C5S. I probably am not answering your question. I can access the computers from my home(I also have a CG computer). Is there some way I can tell you from the C5S program which the info you need? I have it ready to record for next week.
I know how to manipulate various functions but I do not know all the ins and outs of the Premiere settings-an IT man set those up for me two years and he is no longer available.
Thanks

Create and save boolean expressions for later evaluation

Is it possible to create Boolean expressions by inputs via user interface in LabVIEW and save them for later evaluation? I am interested in creating a 'flexible policy engine' which involves creating 'rules' comprising attribute values of certain attributes of objects based on boolean expressions which can later be used for arriving at some decisions based on the 'rules'.

Hi Belur,
Have you considered building a script based on the boolean expressions that you want to create for the flexible policy and saving the script to file?
Later, you can read the script and depending on the policy, it can re-create the boolean expressions.
A simple way to implement this is by having various pre-defined expressions places into a Case Statement. The script calls the appropriate cases that create the complete expression.
You can store the attributes of the objects and when the vi is running, it can first open the initialization file, read the attributes and set them.
For instance, you can read from and write to Property (and Invoke Nodes) to which you can the attributes.
Unfortunately, I don't have an example of this that I c
an share with you. There may be some if you do a search.
Hope this helps..

Video grab and save using labview

Dear All
I am trying to grab and save a video from ni smart camera (NI 1744). I
am using Grab and save vi which is attached. I open a new project in
labview 10. To this project I add the smart camera as a RT target and
then add the attached grab and save vi under the smart camera in the
project. I right click the smart camera and select " Deploy all".
Deployment starts but it terminates displaying the following error
message:
" LabVIEW: Failed to load shared library
nivissvc.*:LV_AviMovieOpen:C. Ensure that the library is present on
the RT target. Use MAX to install NI software or FTP to transfer
custom libraries to the RT target.
Deployment completed with errors "
Kindly note that I am able to grab a video using MAX (Measurement and
Automation) without any problem. I have also re installed IMAQ RT,
Vision RT, IMAQdx RT and Labview RT on the smart camera several times
but that has not solved the problem. I shall be really grateful if
anyone can provide any guidance regarding how to carry out successful
deployment of the attached vi or if anyone can suggest an alternative
way of grabbing and saving a video from NI smart Camera (NI 1744).
System Specifications: Toshiba Satellite Laptop, Windows 7 home
premium. Labview 10.

AVI is still not supported for the 1744, which uses a VxWorks Operating System (as compared with the newer series of smart cameras the 177x which use pharlap OS and support the new AVI functions).
Attached is a sample LV project and code to illustrate how to acquire images on your smart camera and write those to a network image variable. I also made a host side VI to read the image variable where you can use your AVI function to save to your local host machine images acquired from the smart camera.
Hopes thishelps,
Brad
