WEBCAM SNAPSHOT PROBLEM!!

Everytime I try to take a picture, an old snapshot keeps appearing. It refuses to save my new picture.? basically all the pictures I take on my webcam saves as this old snapshot!!! Anyone can help??!!

Just remove the "IMAQ Dispose" and it will certainly work better.
What flows in the image wire is ot the actual image data, but a pointer to the image, so the display on the front panel receives the pointer and go get the image data to display it.
The issue in the VI you posted is that you don't really know when the "IMAQ dispose" will execute, so if if it executes after the "IMAQ create image", the image buffer is released and there is no image data to be displayed.
Hope this helps

Webcam snapshot in flash

I'm mildly familiar with action script. I would like to take
a snapshot from the local webcam and have a preview of the captured
image on the stage, and then upload the captured image to a
ColdFusion server to be saved as a jpg.
After searching online I've found many examples but none of
them work for me. At this time I can only show webcam on the stage.
Could someone help? Thanks in advance!

There is currently a problem (internal bug #2589240) where webcam resolution cannot be increased beyond 320x240 on linux. We're hoping to address this in a future release. Please feel free to ping me with status updates in the future either on this thread or at [email protected]
Thanks,
Chris
Ps. This also effects AIR applications.

Webcam SnapShot button click event

Hello,
I want to know if there is an ActionEvent or EventListener or something
like that for the snapshot button on a webcam, such that when I press the
button on the webcam, JMF executes a chunk of code, just like it would if I
had pressed a mouse button, or a key on the keyboard.
I am currently using creative webcam nx ultra...
Appreciate the help,

Hi there,
I have the exact same problem. I am pretty sure Java will not provide such event support, unless digging the jUSB/JSR-80 stuff. I actually had a quick look at that and I am not even sure what to expect from it.
In any case, if you found any way to receive the snpashot button events (or any workaround), I'd be happy to hear from it!
Cheers.

Acquire a USB Camera Image 1.vi ‏73 KB

Hi qurrr,
Your VI worked fine on my system with my Creative Live! USB camera without requiring any modifications. Are you getting any errors when you try to access your camera?
Are your USB cameras DirectShow compliant? They need to be in order to access them using IMAQ for USB (for example, is the "USB Camera" string indicator you have on the front panel filling in with the name of your camera OK?).
Another possibility is that your are disabling the "snapshot" property of the Image Viewer on your front panel, but in the VI you posted it was still enabled properly. If it was disabled, then when you dispose of the image, it would clear the image display because they would both be pointing to the same space in memory. Please take a look at the following KnowledgeBase articles to see what I mean there:
KB 3NDH344Y: IMAQ Image Display Indicator Changes Throughout Execution of VI
KB 3NRFH84Y: Image Display Refreshing in LabVIEW
To ensure your image display would be updated before your dispose is called, you could change your simple VI to be like the screenshot I've included, where you put the display indicator in a flat sequence with the IMAQ USB Close VI, so that you force it to get called before the IMAQ Dispose VI.

Xcode snapshots problems

It seems in Xcode I'm at a point where the snapshots will no longer work for me. When I make a new snapshot, it always shows every file in the project in the "Files Added" category and there will not ever be files in the "Files Changed" category. Older snapshots a few files in the "Files Changed" category but no new ones do.
Does anyone know what to do here?
I've tried removing directories in ArchiveDirectories, editing the Snapshots plist file, removing the snapshots image (~Library/Application Support/Developer/Shared/SnapshotRepository.sparseimage), among other things.

That was easy. The DU output appears in the console log. Here it is:

Doesn't look like it should have helped Xcode at all. This is what I remember with certainty:
1. I made a snapshot days after installing the 10.5.6 update (directly from Software Update.)
2. I got the "(no changes)" message when comparing that snapshot with the previous one.
3. I quit Xcode, relaunched, and the problem had disappeared. All diffs showed up.
4. Days later, I made another snapshot and "(no changes)" appeared when comparing any snapshots. This time, quitting and relaunching Xcode didn't help at all. The 12-15 and 12-20 folders contained identical files despite my having made many changes.
5. I tried restoring the SnapshotRepository.sparseimage via Time Machine, mounting the image and looking for missing files, etc. Couldn't find any signs of corruption. Never touched any preferences files though. Nothing helped. This is when I made my original post.
6. Ran DU "repair permissions" just for grins, and suddenly "it just worked." The latest snapshot that I had made (the one that that seemed to trigger the problem) and all others now show the expected diffs, some of which are quite extensive changes.
7. Subsequent snapshots also show the correct diffs. So I thought DU had fixed the problem. Maybe not.
Now, here are some things that I did that directly affected the repository image. I just can't remember exactly when I did them:
- At some point I deleted a snapshot using the Xcode interface by choosing a snapshot and clicking Delete. I can't remember exactly, but I'm pretty sure I deleted the last one at the time (dated 12-20, which, when I mounted the image, contained files that were physically identical to the 12-15 snapshot's.) This would have probably happened at some point between steps 5 and 6 above, but I'm not sure.
- I'm pretty sure I made at least one other snapshot on the 20th, got the same "no changes" message, and just gave up fiddling around. Waited a few days, made a few more changes, then posted here.
Sorry for burning up all that bandwidth. It really doesn't look like permissions could have caused the original problem (the 12-15 and 12-20 snapshots containing identical files despite my changes in Xcode.) But somehow things are fine now.

Vivtar Webcam driver problem in Windows 7 Enterprise x64

Hi all, I had not long purchased a Vivitar DVR 708HD Camcorder and the camera itself is rather poor, but I was impressed with it's webcam function back when I had it working on a different computer. I'm not an amature as I'm usually quite good at finding
device drivers as I did a lot of manual driver installations in Windows 98 and 95 but this one as stumped me. The even more annoying thing is, I have lost the OEM disk for the camera (although, I wasn't entitrely sure if it contained a device driver for it)
and I have got it to work once but that was in Windows 7 Ultimate x86. Now my computer is running a 64 bit version of Windows (Windows 7 Enterprise to be precise, as described in the title) and I know some drivers do not like running in 64 bit if they are
not native to them but I was wondering if anybody possibly knows how to sort this. If it is a compatibility issue with 64 bit operating systems then so be it but I was hoping somebody could assist me with this and possibly find a driver solution to work this
camera.
If you need the Hardware Identifications here they are:
USB\VID_04FC&PID_1628&REV_0100&MI_02
USB\VID_04FC&PID_1628&MI_02
I suppose it could also be possible that Vivitar features a different type of Firmware for this cameras I'm not sure but good luck if you can help!

I'm having the same trouble - following
FlashGuru's
Tutorial.
I have the webcam feed working fine. On one frame I put the
code and i have defined a movieclip with the name snap_btn. It
creates the blank bitmap but won't fill it with the image. I don't
think the button works either.
anybody help?

Code follows:

Webcam snapshot to jpeg

I want to take a singel frame snapshot of a webcam image,
which is streaming to a server, and send it to a JSP server and
make it a JPEG. How can I do it? Isn't there a simple way? With few
lines of code? To make a byte array, perhaps and send it through
http?

In photoshop see if File>Scripts>Image Processor works.

Capture webcam snapshot as bitmap and send to server

I have a local webcam stream appearing on the stage in a
movieclip.
When I click a "snapshot button", a still image from the
webcam gets attached to a new movieclip on the stage with
attachbitmap and then draw()
The snapshot shows up in the movieclip on the stage as a
preview.
I want to know how to send the data of this bitmap in the
movieclip to a server (php or coldfusion) to be saved as a JPEG.
I can't figure out how to access the bmp data and send it to
a server... any answers?

Hello jspoon27,
I am working on a locally run flash application that is very
similar to your post about wanting to save a snapshot of a local
webcam. Could you share your code for doing that or explain your
steps? I would like to have a webcam running then take a snapshot
of the webcam with a button and then email the saved snapshot. My
main interest is how you created the snapshot and button for it.
Thank you,

Webcam BitmapData problem

Hi all,
I'm trying to make a webcam app, using a microsoft Lifecam
VX-1000 and Flash Pro 8. It has 320x240 resolution. I capture the
camera image using
var image:BitmapData = new BitmapData(_root.view.width,
_root.view.height);
image.draw(_root.view);
where view is my camera object.
The problem is, in the capture, my image is squished into the
top left fourth of the screen, and the rest of the capture is white
space.
I'm doing image processing, so I need the full resolution.
An image that explains what I'm talking about:

Thanks for taking the time!
matt carlin

I've run into this as well. It is some ratio between the
resolution of the camera and the video instance showing it –
I've actually run into it with an external FLV, but I'm sure it is
the same issue. I was making that popular reflected video on a
polished black surface effect. I don't know why it is and I don't
know how to actually fix the problem, but a patch/bandaid approach
is:
bmp = new BitmapData(myVideo._width,myVideo._ height, false,
0xff0000);
mtx = new Matrix();
mtx.scale(myVideo._xscale/100,-myVideo._yscale/100);
bmp.draw(myVideo,mtx);
In my case I only created the bitmap and the scale matrix
once, and then the draw method was called repeatedly later.
If anybody has an actual solution I would love to fine
out!

Webcam sound problems!!

while using webcam to talk to my aunt, she can only see me but I can see and hear her....no sound on her end. Her speakers work for other sounds like internet games and stuff like that. We both have HP laptops with built-in webcams. I have used my webcam with other people and the sound works just fine telling me that the problem is on her end. Please help!!!
This question was solved.
View Solution.

Hi Shellee,
Here are a couple of things your aunt can check...
You didn't say what kind of service you are using to talk to your Aunt with the Webcam, though. so I am guessing. If your service is different, the idea will be the same - just look for the same "sort of thing" under her service, there is usually an "Options" setting and they work pretty much the same way for all sorts of programs and services...
You didn't say what Operating System you are using. This information is for Windows 7. Vista works about the same way. XP... not so much, but you may find your way through it.
On her notebook, your Aunt can make sure her Sound is set up to come through her main notebook speakers.
Bring up the Sound Menu:
Taskbar > Right-Click on Sound Icon > Playback Devices > Playback >
Assure "Speakers and Headphones" are "SET DEFAULT" (Green Checked)
If the notebook speakers are not already marked with a green "CHECK" mark, ask your Aunt to Left-Click on "speakers and headphones" to highlight the selection. Click "Set Default"
Second Check:
On this same menu spot..
Right-Click on "Speakers and Headphones" > Check list that comes up
(If your Aunt sees "Disable" in the llist, then Speakers are "enabled" and ready to be used - this is Good.)
Click OK (and done here)
=========================================================================
If using Skype, Latest Version (April 2012)
Skype > Tools > Options > Audio Settings > Speakers > Drop-down menu
Have your Aunt make sure that "Speakers and Headphones" is selected, just like on the Sound icon in her regular sound settings. There may be more than one setting in that Speakers drop-down menu, have her click on it and check it. You may have to hold up a sign or send her this post... Smiling.
I do not know if this is what you are looking for... it may help you find out where to start looking and figure out where to poke at it so you can fix it with her.
Good Luck!

Video Blaster Webcam Installation problem

I got a new PC (OS : Windows XP). When I'm trying to install my Video Blaster Webcam Go Plus, I am encountering an error msg: "The software you are installing has not passed Windows Logo testing to verify with Windows XP." What scared me was the next line.."Continuing your installation of this software may impair or destabilize the correct operation of your system either immediately or in the future. Microsoft strongly recommends that you stop the installation and contact the hardware vendor for software that has passed the Windows logo testing." I tried to get downloads specifically for XP but I am still encountering the same problem. SOMEBODY HELP ME PLS. THANKS!!

Manos,
The Video Blaster Webcam 3 is an archived product. Did you just purchase it? If that is the case, it would recommended to return the product for a newer model.
The last driver release was back in 2002 and the driver only supports up to Windows XP. There has been no further driver development for this model ever since.
