Problem with webcam capture

Dear all,
Using the Peter Parente's "webcam capture" library (Webcam Continuous Capture.vi), I faced some problems. In fact instead of showing for example one 320*240 picture it displayed some smaller pictures with some other parts of the picture indicator left blank(black).
What's the problem. Any help would be appreciated.
Regards

Hello Smal,
I did a search for this library and it looks like it was developed some time ago. The FAQ on the download page seems to indicate that you need to make sure that your acquisition parameters in Windows and LabVIEW need to match in order for this to work properly. There was also a data type change between Vision 6.1 and 7.0 so that could be related, but it sounds more likely it is something else.
If your camera is DirectShow compatible and you have Vision, you can try IMAQ for USB. This, like Peter Parente's Library, is not actively being developed or supported by National Instruments Applications Engineers, but you may have some more luck, assuming you are using more recent versions of LabVIEW and Vision.
If there is a problem with a specific VI, please try to narrow down where the problem is occurring. You may be able to post an image that might indicate how the library is failing.
I hope this helps! Good luck with your application.

Angela

Are they custom EQ settings in iTunes on the computer?
Per:
https://discussions.apple.com/message/17383922#17383922
"Do the EQ settings from my iTunes library transfer to my iPhone when I sync it"
Yes.
" thus causing my iPhone to over process the data when I turn it's EQ on? "
No. If the EQ ison, the iPhone will use the EQ setting you assigned in iTunes. It will use only the preset EQ. If you have a custom setting or do not have an EQ setting, it will not be used and will use the setting on the iPhone.

Problem with Video capture Device

i have a problem with FME. i am using Avermedia TV capture
device and Canon 3ccd Digital Video Camcorder ( PAL ) when i open
the FME interface the warning given for " Problem with Video
Capture Device".
i read all the topics in Flash Media Encoder Category, if
this problem occures my capture device ( i expect MPEG ) how to
solve this problem?
Thanks,

The Device Matrix is something we'll be updating in the
future as we continue to test more and more equipement. Ideally, I
would like for users such as yourselves to be able to add to it and
tell us what has worked for you as well. If anyone has any ideas
about what technology we should use to do this (e.g., this forum? a
wiki?) please let me know.
Regarding the devices not working - the main problem we see
is that the system requirements are not being met. Here is what to
check for:
- are you running on Windows XP (only supported OS right
now)?
- do you have DirectX client runtime version 9c or higher
installed?
- do you have hardware acceleration enabled?
- do you have 32bit graphics enabled?
- do you have the latest direct show drivers from the
card/device manufacturer?
Thanks,

The second message that you are getting "The selected audio device "Beholder Aud Capture (SAA7135)" doesn't allow setting volume intensity. Disabling the volume slider control." is because your device does not let you change intensity of volume. This warning message is just to tell user that volume slider will remain disabled for the selecetd device. This is new addition in FMLE 3.0 and was not there in FMLE 2.5
Also for first message, please make sure that no other instance of FMLE is already running using this device. You can verify this from task manager. If any other instance of FMLE is running then please close that instance so that device gets free for new instance.

Problem with Video Capture, and question towards solution

Yesterday I worked on a commercial for which we captured 9 clips (roughly 10 seconds or shorter in length). The clips all had text/titles superimposed on them by an outside machine and looked good in the monitors when they were exported and captured into FCP (ie: none of the text was chopped off).
I edited the commercial and then was exporting it out, only to discover that the text on the bottom of the clips was getting chopped off.
My first question is this: is there some setting in the capture process that could have done this? something that might have gotten tweaked accidently, or corrupted in some manner? Didn't have this problem with footage captured the previous day. And since it looked good before it was put into FCP, thinking it had to be a problem with FCP.
Also, in trying to tweak the footage in FCP, I came across a 'there must be an easier way to do it' question. Is there a way to alter parameters on multiple clips (such as raising them, like I had to)? I tried selecting all and double clicking, hoping that the changes I made would affect them all, but it only affected the one I directly clicked. I'm sure there's something simple (and obvious) that I'm overlooking...
thanks!

For how and why this could have happened, would you mind sharing your capture and sequence settings?
As far as applying parameters to multiple clips, I think you can make use of the Paste Attributes function in FCP...
Alter one of your problematic clips
Select that clip in the Timeline, then press Command-C (or control-click and choose Copy from the contextual menu)
Select the remainder of your problematic clips
With your clips selected press Option-V (or control-click on one of them and select Paste Attributes from the contextual menu) to bring up the Paste Attributes dialog
Select Basic Motion - under the Video options, on your left-hand side - then click OK
(Basic Motion because, if I understand your solution correctly, you altered the Center property - either in the Motion tab of the Viewer or manually in the Canvas - of your clips. You nudged them all up a bit, right? If you did, then that would fall under the Basic Motion attribute.)
All your selected clips should be nudged up appropriately.
But, again, I'm making a bit of leap since I'm not entirely sure what caused your issue in the first place.

Problem with image capture

I am having a weird issue with Image capture. When I connect my digital camera, my computer does not always recognize that there is a digital camera being attached, so I can not get the camera to mount and get the pictures of the camera.
It is not a cable issue. The camera mounts instantly when I use a Win 2000 machine that I have at work using the same cable. I have tried to reformat the SD card several times.
I have OS 10.4.8 on a 17 inch iMac Rev B). I have iPhoto v 5.0.4. This used to work very well initially, and has steadily gotten worse.
Any tips? Thanks
17 iMac Rev B Mac OS X (10.4.1)

Hi, Romulo.
1. What make/model of camera? Is it listed on the Mac OS X Digital Camera Support page?
2. Since you've mentioned Image Capture, I presume you do not mean iPhoto, i.e. you expect the Image Capture application (located in the Macintosh HD > Applications folder) to launch when you connect the camera. Is the camera recognized in iPhoto?
3. Try connecting the camera to a different USB port on your Mac. If you're connecting the camera to a USB hub (and your keyboard is a USB hub), try connecting the camera to a USB port directly on your Mac.
4. Is the camera battery fully charged, or is the camera powered via an AC power supply when you connect it to the Mac?
5. Try deleting the Image Capture preferences. There are at least four preferences files associated with Image Capture:• The file com.apple.ImageCaptureApp.plist in your Home > Library > Preferences folder.
• In your Home > Library > Preferences > ByHost folder, the files:• com.apple.ImageCapture2.xxx.plist
• com.apple.ImageCaptureExtension2.xxx.plist
• com.apple.ImageCaptureCamera.xxx.plist
where xxx is an alphanumeric string.6. You indicated the problem is intermittent: are you using certain other USB peripherals when the problem occurs vs. when it does not?
7. Immediately after the problem occurs, check the ends of these Console logs for clues. Clues might include messages related to Image Capture or USB at the time the problem occurs.
Good luck!

Problem with Image Capture Download Folders

Hi there - I was wondering if anyone might be able to help with a problem I'm having with Image Capture (version 3.0.3 (333))?
I use image capture to download photos from my digital camera and normally have no problems.
When I tried to do some downloads this morning, my normal list of folders in the "Download to" drop-down box is completely blank. It didn't even have the "Other" option to chose a folder. The Automatic Task drop down was also blank, I could not open preferences and in the "options" box, the ColourSync profile would not load anything.
I could not download the photos to anywhere - when I tried to "download some" it gave me an error message saying that I need to choose a download folder, but of course I am unable to do this.
This morning I tried repairing permissions in disk utilities, and removing the com.apple.imagecaptureapplist file and rebooting as suggested here:
http://discussions.apple.com/thread.jspa?messageID=10368631&#10368631
but that hasn't worked completely. I can now download the photos but they just automatically go to the "Pictures". At least I can download them now, but if I can get the two drop down boxes working again, and the other things working (preferences etc), that would be great.
One other thing, about a month ago I foolishly tried to rename my Home Folder without doing it the proper way. I had thought I had gotten everything back to normal with my library etc, but maybe there are a few unknown implications still out there, and this is one of them as I don't think I have tried to download any photos since then.
Your help is greatly appreciated!
Thanks,
Antony

Hi and thanks again
OK:
1. I found the photo and have put it back as the login page icon as close as I could to what it used to look like..
2. I trashed the user's .com.apple.systempreference file but it didn't work.
3. I then copied my .com.apple.systempreference file to their library>preferences folder but no luck.
4. Finally, I noticed the other user account had no system preferences file in their "Applications" folder. So I copied the system preferences file from my application folder across and used that to open system preferences, and that has seemed to fix it, ie. system preferences now opens directly from the apple menu.
So I am noticing a few things now:
5. The other user's "Applications" folder doesn't have many applications in it. It only has:
- Utilities
- Adobe Version Cue CS2
- Real Player
- iTunes (which was only downloaded there recently - post Home Folder name change I think)
- Imagecapture which I copied there yesterday
- and now System preferences
6. This is compared to my user account applications folder which has loads of other files in it, eg. Preview, Stuffit Expander, iDVD, iChat, Calculator, Chess, Skype, etc etc etc. I just can't remember if this was the case before the Home Folder rename.
7. Now, my user account used to be the only admin account, so it makes sense that my "Applications Folder" has more in it because programs could only have been downloaded there for a long time. The other person's user account has only been an admin account much more recently - say in the last year and very few applications (if any) would have been downloaded there.
8. Interestingly, while the other user account doesn't have the Skype or Preview file in their "Applications" folder, it does appear in their bar along the bottom of the screen that has the dashboard and finder icons (is this called the dock?).
9. Anyway, if you are in the other user's account and you click on Skype, iCal, Word or Preview in their Dock for example, those programs open no problem so the dock icons must somehow have survived the Home Folder renaming and stayed linked to the corresponding files in my "Applications" folder? But some other programs, eg. system preferences, image capture etc didn't survive it and became "delinked".
10. I also notice internetconnect still works in the other user account, even though there is no internetconnect file in that user's "Applications" folder.
11. So it seems that some links between the other user and my account have been severed, and some have survived.
Some other information:
12. Everything that was on the other user's desktop appears to have been recovered since the Home Folder debacle (I think getting the Library back helped this?), and I managed to redo the desktop picture/wallpaper.
13. I'm not sure if it is relevant, but in my account, Finder has a side bar on the left that is divided into an upper section and a lower section. The lower section has my home folder, a documents folder, a desktop folder, a pictures folder etc. On the upper section it has the macintosh disk icon, and also a Network Icon (that contains a library file and another file which I can't remember just now but can let you know if that helps). The other user account does not have the Network icon however. Do you think this might make a difference?
14. In addition to the other user account there is also a guest account on this computer which has suffered the same problems, eg. not being able to open imagecapture or systempreferences. However, when I fixed the problems in the other user account by copying over the imagecapture and system preferences files from my account to the other user account, the problems in the guest account were automatically fixed!
15. So it seems the guest login is somehow linked to the fixes in the other user account, but the other user account and the guest account are suffering some problems with links to my user account. Perhaps the latter was badly broken with the Home Folder rename incident?
16. Finally, if you go into Finder while in the other user's account, you can navigate to the applications folder in my account and access all the applications there, ie. Macintosh HD>Users>MyHomeFolderName>Applications. My applications folder is not blocked like some of the other ones, eg. Library, Desktop, Pictures etc.
17. Is there someway to re-establish the link between the other user account and my application's folder? I don't want to copy all the applications across even if I can do that, because it just takes up more space on the HD, but if that is all that can be done, then I will consider doing it...
Thanks again BDAqua!

Problem with change capture

HI,
we've a problem with the Change Capture in the DAC's Execution Plan.
We've cretead a new data model but we want to reuse the image table and the Change Capture process, so we've perfomed the following step:
1) create the mapping SDE e SIL for the new tables of datamodel in Informatica Power Center
2) register these mapping in the DAC
3) create a subject areas and associate these tasks to this
4) create execution plan including "change capture" and "change capture sync"
5) execute our "execution plan"
the problem is the following:
from the Execute -> Current Run Tab -> task
we can see that execution time of change capture is 0
from the Execute -> Current Run Tab -> task details
there aren't any change capture details
So, our image table are empty.
Do you have any idea?
Thanks in advance,
Antonello.

HI Antonello,
I am also having the same issue like you. I have created a new execution plan in DAC 101341 and ran it. It seems like the task Change Capture For Siebel OLTP completed in 0 seconds and there are no details for that particular task. Can you please let me know if you have resolved this issue? Your help is much appreciated.
Thanks

Another Epson scanning problem with Image Capture

I've been having problems scanning with an Epson CX5600 for the previous month. I can print just fine, just can't scan with Image Capture or Vuescan (not so good free software). I always get "An error occurred during scan". I've tried repairing permissions, installing Gutenprint/cups drivers, all epson drivers on the site, and deleting ALL drivers in /Library/Printers/, which later it proceeded to download the Epson drivers automatically and still fail. Any idea? My dad's unibody MacBook works just fine with Photoimpression 5 and Image Capture.

Stratosphere- Problem with Screen Capture and Group Text Reply

I have a problem with the side button that locks/unlocks the phone. I don't know why it happens but sometimes when I press the side button to lock the phone it takes a screen shot and send its to my Gallery under the folder ScreenCapture. I can't figure out why it does this sometimes, and when i want to actually take a screen shot I cant.
Anyone know how exactly you can take a screen shot?
Another question i have is with Group Texts. Is there a way to reply all when I receive a text that was sent to multiple people or can I only reply to the sender?
Hope someone can help thanks!

Hello kfeatherstone! I can provide you with instructions for taking a screenshot:
1. Press both the Power and Home buttons briefly.
2. You should hear a “click” sound and the screen will say “Screen captured. Saved as image file
In regards to your messaging, "reply to all" is not an available option. I hope this information helps!

Problems with Auto Capture

Hi - we are evaluating the trial version of Captivate to see
whether we can create demos/tutorials of our desktop software.
We're using auto-capture to record screen actions, so it does a
screen capture each time we use the mouse to click a button. When
we look at the slides after capturing them, many of the slides show
random parts of the underlying window superimposed over the dialog
box, as though the screen was captured while it was being
refreshed. So I have 2 questions:
1. Is there any way to prevent this from happening?
2. If not, and if we need to use manual screen captures to
replace any gunked-up automatically-captured screens, how do we
move the mouse click action from the auto slide to the equivalent
manual slide? Captivate will let us move other things on the
timeline between slides, but doesn't seem to want to let us move
the mouse object.
I'm sorry if this isn't clear; we're still quite new at this!
Thank you.
- Alma Taylor-Smyth

Hi Alma Taylor-Smyth and welcome to our community
Note that you can actually use a
combination of manually pressing print screen to take
additional screen captures. So as you use Captivate, you can easily
supplement your auto captures with manual captures. Unfortunately,
there is simply no way I'm aware of to prevent those screens
(partial or blank) from being recorded. Captivate runs locally and
captures very fast. So if that screen hasn't had time to properly
render (as is often the case with Internet/Intranet applications)
it grabs the screen in partial and empty states sometimes.
As for the mouse movement, note that all Captivate really
records is the ending point and whether there is a click or not. If
you right click the slide, you can easily point at Mouse and then
"Show Mouse". Then configure the ending point, desired click
actions and other options. (to get at these options, double click
the Mouse object in the Timeline)
Hopefully this helps... Rick :)
