Can you tell me a simple way or link to software that I can use to block flash from uploading images from my computer in chat sites to other users???
I have disconnected and removed my built in webcam but it still streams images, possible
because I have the HP Pavillion connected to a PLASMA Monitor which confuses me because it does not have a camera on it!!!
I have research possibility's of stopping this but found no answer, I will really appreciate it if you would be so kind to explain a way to stop or block this from occurring?
Flash will usually throw a 'allow/deny' box up at you if it wants to to access any other hardware like your webcam.
So just don't 'allow' it.
You can check if you have a webcam via your device manager.
Assuming you're using Windows 7:
Press start,
Type "device manager"
Press enter and search through seeing if you can find your webcam. If there is one it should be under 'sound video and game controllers'
If you do find it. Right click on it and 'disable' it.
Good Luck.

Since the latest update (I think some time in December 2022), the built-in camera app on my Samsung Galaxy S21 asks for "Nearby devices" permission, and refuses to run if I don't grant it. By "Nearby devices" it means "Bluetooth". I don't know why it calls the permission
"Nearby devices": all other references to Bluetooth call it "Bluetooth",
and you can also access a nearby device using Wi-Fi or even NFC if the device
is close enough.
It doesn't actually need Bluetooth to take photographs, or even to record movies,
but you might have a Bluetooth microphone (I don't) and you might want to use
it to get better sound quality when recording a movie.
Of course the Android best practice advice at
https://developer.android.com/guide/topics/permissions/overview
is not to ask for runtime permissions unless and until you need them,
but Samsung aren't doing that.
I don't want the camera app to announce my presence by probing the Bluetooth headset of
anyone who happens to be near me, and they might regard such an action as intrusive.
So I don't want to give the camera app its nearby devices permission, but it won't
run at all without it.
So how do I get the camera app to run without accessing Bluetooth?
I found some workarounds for this. If your device supports it, you can download Expert Raw from the Galaxy Store. This will take still photos without requiring "Nearby devices" permission. However it doesn't seem to be able to do selfies because there seems to be no way to switch cameras, and it can't do movies or many of the extra tricks that the full camera app can do.
Another option is to run the camera app with Bluetooth disabled. Then it can have its "Nearby devices" permission, but it can't use it. The problem with this is that if you use Bluetooth at other times you have to remember to disable it and enable it.
So I wrote a tiny app which disables Bluetooth, runs the camera app, and restores the previous enabled or disabled state of Bluetooth when the camera app exits. I put this on my home screen instead of the camera app: it has the same icon. You have to remember to exit properly from the camera app using the Back button: the Home or Recents buttons leave my app and the camera app sitting on the task's back stack, so my app doesn't get to run and restore the Bluetooth state.
The app is available on github here in case anyone else wants to use this solution.
I'd like to write an app for My Band2 that should be able to simply change the audio track when I hit a button on my Band2. I'll use this because my car can't Play Audio via Bluetooth. So I bought a Bluetooth dongle but I'm unable to change tracks or simply to pause it. So a 3 button app on my Band2 should do a good job.
I've found a lot of examples to do so with Background Audio Players in a self written app.
But I'd like to remote Control the standard player, which is Groove-Music for me.
Any suggestions to do so? Can you please give me a start on that?
Thanks,
Jo
Recently, my computer has been acting rather strange. All audio is muted and any time I try to watch a Youtube video the player ends up crashing. I can't seem to find anyone who has had a similar problem but I think I may have found some kind of clue: While trying to run a project I made in C++/python for the Panda3d engine I kept on getting these errors:
AL lib: DoReset: Failed to initialize audio client:0x8889000f
:audio(error): alcCreateContext(_device,NULL): Invalid Device
:audio(error): OpenALAudioManager: No open device or context
I have no idea what this means as I am not very knowledgeable of computers.
it is hard to say a lot without more details, but it appears as though the computer is not detecting your audio device. Try right clicking on the computer icon in metro, and selecting manage. Go to the device manager and see if there are any devices that have a yellow exclamation point. if they do, install drivers from the vendor. If not try updating your audio drivers, and restarting.
I recently downloaded a barcode reading application for my phone, an LG KU990i (AKA the Viewty) However, there's a problem that renders the application nearly useless: the Viewty has 2 cameras -- the main one, and a secondary camera located on the face of the unit -- and it is the secondary camera that is unfortunately set as the phone's default video capture device. As you can't point the secondary at anything and see what it's pointing at at the same time, it makes it a bit difficult to snap a barcode!
According to the JSR-135 spec, it is possible to specify a video capture device other than the default... if you know the device name. This does not appear to be documented anywhere on LG's Web site, nor does the JSR-135 spec describe any way of enumerating the devices on a phone... or is there? Failing that, are there any naming conventions for video devices commonly in use that LG might be using?
I've logged a ticket with LG, but as it's an old device, I don't imagine them breaking their backs in getting back to me... I should also point out that this is purely for my own curiosity so no-one here should feel obliged to break their backs either!
As far as I know there is no way to get list of all available catpure:// urls.
All urls I know:
capture://image,
capture://video
capture://devcam0
capture://devcam1

LG responded to my support ticket. Apparently, it's not possible to access the primary camera on the Viewty from Java, making it pretty much useless for barcode scanning. Answer reproduced here for search engines.

KU990i default video capture device is the secondary camera
Answer :
Hi,
KU990i have to Two camera module
differently.
Main camera using Joran chipset and
sub(front camera) using Qualcomm
chipset.
Joran chip doesn’t supported JSR135.
Therefore, we couldn’t supported to
the JSR135 using for main camera.
(it is H/W limitation)
It was inform to operator already and
we remember operator was confirm it.
So that, we only supported sub camera
for JSR135.
BR,
I am working on project where I need to catch the image capture event.
It's for nokia N73 having platform S60 3rd edition.
Is there any possible way using J2ME only (without using symbian).
Description:
J2ME application running in background, on click of capturing image from camera J2ME application initiates and comes in front. Takes the captured image and transfers it to J2ME app and displays on screen.
if not possible using J2ME , Is there any possible way using symbian? can anyone provide tutorial or code snippet?
Thank you.
Regards,
Rajiv
Not possible to access the native camera from J2ME. You'd need to get the user to start your app first, then access the camera from your app (using JSR 135, spec here, introduction and examples here). Then you can use the captured image however you wish.
HTH
The N73 in particular has a fairly large hardware limitation when you want to use the camera.
You need to have the user manually open the camera cover before you can use the camera.
This launches the native camera application included in S60.
The user then needs to close that application.
From that point on, J2ME can use the camera, via the mobile media API defined in JSR-135.
If the user reboots the phone, the camera cover needs to be re-opened before J2ME can use the camera again.
You may have better luck using J2ME and JSR-135 to capture images using the front camera on the N73.
I seriously doubt that J2ME would see the user pressing the camera key in javax.microedition.lcdui.Canvas.keyPressed();
JSR-135 doesn't really provide a system-wide camera capture event for J2ME.
