Error -1074395975 occurred at IMAQ AVI Read Frame DirectX has timed out readin

When i run the "Read AVI Example" on every kind of AVI file, I get the error:
Error -1074395975 occurred at IMAQ AVI Read Frame DirectX has timed out reading or writing the AVI file. When closing an AVI file, try adding an additional delay. When reading an AVI file, try reducing CPU and disk load.

The forums search gives two threads talking about this error:

vicbit ....tal vez se podría revisar un ejemplo para la versión 2013 que podría servir ...... llamado "Read AVI File.VI" que se encuentra en la ayuda..... como menciona Omar las funciones relacionadas con el manejos de archivos AVI, fueron cambiados en la ultimas versiones asi que saldrá un poco diferente o tal vez el ejemplo no se encuentre . Yo pienso que el truco radica en el uso adecuado de los " Frames per Second" ,"Number de frames" y el "time Delay".
Algo que observe en los códigos que han subido anteriormente es que no es necesario usar dentro del ciclo la funcion "Imaq Create" ya que va a crear un espacio en memoria cada vez que se ejecuta un ciclo (Cada frame) esto no es necesario y podria afectar , además no se estan liberando estos espacios con "Imaq Dispose VI".
A continuacion la imagen del ejemplo que se encuentra en la versión 2013
en la versión 2010 se puede encontrar ejemplos también-->https://decibel.ni.com/content/docs/DOC-14904

IMAQ AVI Read Frame vs. IMAQ AVI2 Read Frame, no data terminal

Hi,
I just noticed when dropping a IMAQ AVI2 Read Frame vi in place of an older IMAQ AVI Read Frame vi, there is no "data out" terminal. I do make use of this feature to add data to the frames of the AVI. Is there supposed to be an alternative way to store this frame data, using the imaq image custom info perhaps?

Hello David,
You are correct in that the data out terminal is no longer available in the AVI2 functions. However you can use the IMAQ Read Custom Data and IMAQ Write Custom Data functions. These allow you to write and read custom data to the IMAQ images using specified keys. In this way you can add miscellaneous data to your images for later use.

IMAQ AVI read frame error

Hello,
What does the IMAQ AVI read frame error "Trigger Time out" mean ?
Thank you.

Hello Vanessa,
In some applications, when a trigger occurs after several minutes or when integration takes several seconds, the timeout parameter may be too small to wait the amount of time it takes to acquire an image. If the image you request is not ready by the timeout parameter, the acquisition code generates a timeout error.
To prevent this problem, check the acquisition status and request an image only when you know one is ready. By just checking the acquisition status and not requesting an image, you could wait indefinitely for an image without receiving an error.

IMAQ AVI read frame performance

I've been playing around with the read AVI with buffer example in the Developer Community. It reads all the frames of an AVI into memory and then plays them back at the appropriate frame rate. This works ok with very small AVI files but with anything larger it gets slower and slower until it almost stops loading the AVI. At that point it seems to be loading less than 5 frames per second and is killing my cpu. I have plenty of free RAM during this.
https://decibel.ni.com/content/docs/DOC-8479
This is the case with the play AVI example that comes with Labview too (without a buffer) which just loads and plays one frame at a time. Can someone suggest a way to improve the performance of an AVI player in Labview? My ultimate goal is to read an AVI and detect changes in motion of objects by comparing two frames at a time. These AVIs are going to be at least 5 minutes in duration at a frame rate of 30 fps.
I'm using Labview 2009 with the Vision Developer installed.

Hi,
One thing we could implement is a compression filter that is on the IMAQ AVI Create VI used in conjunction with the IMAQ AVI Get Filter Names VI. Also, what is the RAM available on your computer and what size images are you acquiring and saving to AVI? Thanks!
Kim
Thanks for replying. I'm running labview 2009 on a dual core pentium 2.3 GHz with 4 Gigs of ram. It typically has 2 Gigs free while running the program.
I'm not tryingt write an AVI, I'm trying to read an AVI. The frames are 352 x 240 in size. I've tried several read AVI examples and they all act the same way. They slow down quickly and the hard drive and CPU are really cranking away.

IMAQ AVI Read Frame Trigger Error

I have an application that is creating avi clips of a process. This application is writing frame data which is read later in another application. It is at this point, during the reading of the data that an Error -1074396037 Trigger error is occuring. I am using IMAQ Vision 7.0 and Labview 7.0. Attached is an avi that was created. It consists of a total of 75 frames. Also attached is a simplified version of the frame read part of my application. When reading the frame data I get the error at frames 36 and 51.
I was hoping somebody could have a look and see why I am getting the error.

Hi Terry,
I ran your program with your video and got error 1074395975 DirectX has timed out reading the avi file. I do not think there is anything wrong with your program because I ran your program with a different avi file and it worked perfectly. I also ran the shipping example Read AVI Example.vi with your video and got the same timeout error.
So there must be something wrong with your avi file. Perhaps frames 36 and 51 are missing or corrupt for some reason. Try creating the avi file again and see if you still have the same problem. If you do, then we'll have to investigate the problem with the creation of the file.

Reading frames in avi files

When reading large AVI files, I get an error when trying to read frame 870 or higher:
Error -1074395967 occurred at IMAQ AVI2 Read Frame
Possible reason(s):
IMAQ Vision: (Hex 0xBFF604C1) Error reading AVI frame
Is this a limitation of the system? I have the problem even when using the AVI read example.
Solved!
Go to Solution.

I have to disagree. I do not use old functions. The test program is very simple (see the picture). But video contains over 60,000 images (640x480, 8-bit grayscale, no compression). This example hangs on image 3474.

What type of AVI files will IMAQ routines open/read?

It's been recommended that to be able to use images from DV firewire
cameras with IMAQ the way to do it is to capture an AVI file and then
use the open/read AVI Vis to process the frames. When I capture a full
DV file using Pinnacle studio, this captures to a type 2 AVI using the
dvsd codec. Open AVI exits with an error when trying to open these
files. Does it need to be a type 1 AVI or use a particular codec to be
readable by IMAQ?

Hi Russ,
The only caveat on the avi read functions is that the file extension should be .avi
I'm still looking into it but it would be helpful if you could tell me what functions you are trying to use and what error codes you are seeing.
Thanx

Problems using AVI read/write example

I would like to test some vision processing software I wrote by reading an AVI file rather than a live stream. I found the "AVI read/write example" mentioned on this forum and it sounds like exactly what i need, but I cannot get it to read my avi files. When I run the example read VI, it says "An exception occured with the external code called by a call library node". Doing further testing, I found one AVI on my computer that would work, all others crash the VI. Another odd behavior is that the "avi init read" subvi will return the wrong frame rate for some AVIs. I have tried both compressed and uncompressed AVIs all in RGB format. I have also tried different frame rates and encoding options for my AVI file with no luck. I am just a stud
ent, so buying software is not an option for me.
Has anyone had problems reading AVIs with this? Are there AVI encoding options that will make this VI work?

Hello,
I think the avi functions that you get are VFW based, it can not read
any format of compression codec. But it should be able to read
uncompressed AVI files. But anyway, if you can't get IMAQ-vision 7.0
avi functions to try (I don't have, I don't know how it works), you
can always get my IVision to try out. In IVision, there are two groups
of avi functions. One is called "AVI functions", they are VFW based,
so not always work for all kind compressed avi files, but I have
another group called "Media files", the functions there work for all
format compressed AVI files, including mpeg, asf, avi... you can
access the frame image by using a callback vi (example included), seek
the media position, change play rate, etc.

Not enough speed when using AVI read

Hello!
I have a problem with the speed, when I'm using the 'AVI read' VI.
I want to read 60 frames per second, but my test.vi allows to read at least 20 to 30 fps (->33 - 50ms loop time), even when I do it in the easiest way (only the AVIread in the loop without any analize, graphs and of course wait functions).
The VI profiler tells me, that the AVI read VI only needs 1ms per loop. During that the CPU utilization is 10%.
My hard disks are fast enough, because its possible to write more than 60 frames per second in real time.
So, can anybody help me and tell me, where the VI spend its time and how to make it faster???
Thank you,
Gero

Hi all,
i just played around a bit using an advertisment video from Heineken. The default video is set to 24 fps which is displayed as expected.
I converted the video (sadly with a not so good comporession) to 72 fps. In Windows Media Player, i'd say that the 72 fps are maintained.
Using my Player.vi, the video is played with about 40fps on my Laptop. The CPU load is about 15%. So it seem that either my programming is bad or there is a platform dependency in the performance.
Removing the display from the loop (so no visualisation of the video), the performance got up to near 43 fps.
Gero, please confirm if this is the behaviour you are seeing. I asume quite an impact by different platforms, so feel free to check other systems as well.
hope this helps,
Norbert
PS: I split the attachment and repacked the _fast-version using a higher compression (lossy) for a smaller file size.

Avi read write example : playback missing chunk of data at regular intervals

Hi,
I am writing a waveform data into avi write in order to read back (with has data input on) as in example avi read write with data shipping example but the graph played back is missing some amount of data at regular intervals and hence the waveform read back is choppy.
I am writing the same data into tdms also. when i read back it with tdms file viewer, it shows that it has entire data.
note: i am writing the waveform data and avi in two seperate loops and using the porperty node value of the waveform data in the video loop in order to insert data into avi write (has data input on) and have the (wait ms multiple) input =10 in both loops
i would like to post the video but it is 50 MB, is it possible to upload that much.
can any one help me how/why this is happening..
Thanks,

Can you post a VI(s) as I have trouble understanding what you are doing
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Can't read frame from file

We use proxies in our work flow, pre-rendering certain comps before rendering out the final project. For the most part this works fine, but occasionally we'll get an error that reads: "Error (4) reading frame from file." It's always the same comp but it doesn't cause the problem in every project.
We use the quicktime codec with Tiff compression. Could it be a memory issue? Any help would be greatly appreciated. The error always pops up at the most inconvenient time -- of course.
Thanks,
Julian

Well, if it's always the same file, then most likely one of the source footages is really damaged. The error not occuring every time mustn't mean anything. If the element in question is not visible at the given frame or AE doesn't do anything with it because it isn't required, naturally the error would not occur. I'm afraid the only way to track this down is to selectively disable/ remove the sources from the comps in question and render some test clips. Perhaps it would also help to check all the files used in the project in a "neutral" app such as external image and video viewers (XnView, VLC, MediaPlayer Classic...)

IMAQ Vision AVI create - file access denied error

Hello:
I am getting some really strange behavior with the IMAQ Vision AVI create function. I am seeing the following error with the following file name or pretty much any other file name I try. I did try to hard code the same file path name, and one time it worked, but another time it did not. Anyone seen this error before?
I will cross-post in the Vision forum also.
Thanks,
Don

Here is the simple version of the code. I have even gotten out of LabVIEW and then come back in and still could not save to AVI (even if deleting the old file of same name) so not sure what is going on. The error occurs right on the error output of Create AVI.vi...Don
