RGB modes disappeared for webcam

A few months ago I installed JMF in order to use it to capture images from my webcam (Logitch Quickcam Express). JMstudio showed that my webcam supported 10 modes, among which a few RGB modes. I used the RGB modes in my application.
Now I return to my project and suddenly the RGB modes are no longer there. And the YUV modes don't seem to work: I get black screens with some grey lines in the top of the image. This happens both in my application as in JMStudio.
On another computer it still works fine, so it must be something that has changed with the software configuration of my system. Does anyone have a clue what I might to to get the RGB modes back?
Thanks,
Frans.

Did you install another JRE ?
If you, you'll need to reinstall JMF to that JRE
A lesser possibility is that the webcam drivers were
updated ?Hi Owen,
Thanks for thinking along.
I don't think I installed a newer JRE, but I reinstalled JMF nonetheless and sadly that didn't help.
I also reinstalled the original drivers, also to no effect. Perhaps Windows update smuggled something in I didn't notice?

Dock disappears for a few seconds and minimized apps open up

Hello
My dock at the bottom of the display will disappear for a few seconds and at the same time, my minimized open applications will open up. This usually happens when I'm running a few light applications at once. It almost seems to "gulp" or catch it's breath.
I'm not sure if this is related but for the second time since purchasing the machine the dock is showing a sort of double reflection at the very bottom. An open application has what looks like two lit triangles underneath the icon instead of the usual one triangle. The same area at the bottom of the dock shows a very tiny "bottom" of the page I have open, in this case Safari. It also moves left and right as I move the open page left and right. If I move the page down, the sliver at the bottom of the dock moves up.
This is only the second time this has happened. The first time it went away on it's own and today it's back. It's not troublesome at all but I'm just wondering what may be causing these symptoms.
Thanks!

Page background disappears for a moment on page turn in pdf

In indesign my document has a gradient page background (created in indesign) on the master page to make it look like a book. But when the page is turned in pdf, the background disappears for a moment, leaving the page white, then the background appears again; it does this nearly every time page is turned, flashing white. Does this have to do with pdf or indesign layers? I have only 1 layer in the indesign document, and transparency blend space is set to rgb.

Everytime you change the page Acrobat needs to redraw all of the page elements. The dealy is probably a reflection of the amount off video memory available, as much as anything.

Weird bug? Transparent background is black instead of checkerboard in RGB mode

If I try to make a new RGB document with the Background Contents set to Transparent the canvas is filled with black instead of the checkboard pattern. However over in the Layers window the little icon for the layer shows it as transparent with the checkerboard. In the Channels window it also appears transparent, and if I click on one of the channels which selects just one of them the canvas changes from black to the checkboard. If I click on the RGB channel at the top the canvas changes to black again.
Why is this happening and how do I fix it?
If I open a new document in CMYK I get the checkerboard like I'm supposed to.
I bought a new PC a few days ago and this is a fresh install of Adobe CS4 on Windows 7. Photoshop is updated to version 11.0.2.
I could swear this wasn't happening a couple of days ago when I first installed it, and it never happened on my old XP computer.
edit to add: all files show a black background in RGB mode instead of the checkerboard pattern, not just when creating a new document.

What are the Photoshop > Preferences > Transparency & Gamut > Transparency Settings?
Boilerplate-text:
Does turning off OpenGL in the Performance Preferences and restarting Photoshop have any bearing on the issue?
Other than that are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?

Why are my RGB colours dull in illustrator? The doc is set to RGB mode.

Hi,
I'm designing in Illustrator, RGB mode and using RGB colours. However, when I export to png, the colours in the png file are bright and vivid (the correct rgb colours I assume) but in illustrator they are dull. It's making it very hard for me as I actually want the duller colours, not the really bright ones. Attached is a screen shot to show the difference. Left is png, right is ai.

ah, thanks. I never knew that option was there. I just thought that if i'm working with RGB and using RGB colours, then they should output as the same?

Why do my custom swatches revert to RGB mode?

Hi all,
I'm a newbie to Illustrator. I have a few questions:
When I create custom swatches, I choose the CYMK option in the drop down box. However, these swatches are appearing as "RGB" mode in my swatch palette. Why is that? How do I ensure my custom swatches stay in CMYK mode?
When I later view the CMYK code for the swatches, I see that their numbers are skewed a little (for example, 34 may be 35 or 36, etc). Why is that?

When you create a new document, make sure the color mode of the document matches with the swatch color mode. i.e if you're creating a new document in RGB and then using a CMYK swatch then the numbers will be converted to RGB. Make sure the document is also created in CMYK color mode by expanding the advaced options in new document creation dialog box.

Adjusting Black (K) while in RGB mode?

Ok, so basically I'm wokring on an image in RGB mode, and I have my INFO box open, and I have the sample picker #1 and #2 set to display CMYK values.
I'm not sure if many people realize that even if you're in RGB mode you can actually view other color information, including CMYK, within the INFO Box. If you click on the little Eye Dropper icons located within the INFO Box, it allows you to choose between different color info to be displayed, i.e. LAB, HSB, Grayscale, RGB, CMYK, etc, regardless of the color mode you're actually in.
So I'm working on an RGB image, but I'm viewing the color info in CMYK, and my question is how do I directly adjust the K, or black, wihtin an RGB image, if I don't actually have the Black Channel available while I'm using Curves or Levels for example?
I tried using the 'Brightness and Contrast' adjustment, but it affects everything else as well, not just the K/Black.

I'm not really trying to affect the 'Black Channel,' I know it's confusing. In fact, technically, there is no Black Channel to speak of, because I am in fact in RGB mode.
Basically I was just trying to increase K, Black, in the INFO Box, from 0 to 4, under the #2 sampler, without affecting CMY. Because my INFO Box, is set to read CMYK values, but I am still in RGB mode. So I'm not really trying to affect the Black Channel, I'm just trying to affect what's being read as Black, while I'm still in RGB mode.
Right now, it's reading C=11, M=42, Y=51, K=0, and I wanted to change K to 4 without affecting the other colors, without affecting C, M and Y.
I just wanted to see if that was at all possible.
I don't think using another color profile is the path I want to go down. Right now I'm just using the standard sRGB.
I actually had to look up GCR, grey component replacement, and I don't think that's what I'm looking for either.
I just want to make a move in Photoshop that would accomplish changing the Black readout from 0 to 4 with out affecting CMY, or at least minimally affecting CMY.
But I guess it's not really possible at all, using the adjustments and/or the blend modes? I've tried a couple of things and nothing seems to work really.

Color mode & settings for grayscale illustration to monochrome laser printer

Is there a best setting for the mode, color settings, and color profiles when printing a grayscale vector illustration to a monochrome laser printer? I am making vector maps, and right now they are mostly black line and black text with only the K values in CMYK. There are some gray tones—for example water areas are 10% K, with no C, M or Y. Would it make any difference if I used RGB mode values at 100% (255,255,255), or a rich black in CMYK (such as 40C, 30M, 30Y, 100K)?
I printed in K only at 1200dpi to a Generic Gray Gamma 2.2 profile, and it doesn't look too bad. There aren't many of the lines that are really jagged. I just wondered if there are better settings...
I'm using Mac OS 10.6, Illustrator CS6, and a Brother HL-5470DW monochrome laser printer.

Parsa,
Not really (to both).
In some cases, using RGB with a PostScript (emulated) printer, or using CMYK with a non PostScript printer (through a PDF), you may get an unexpected outcome.

Toshiba 23WL56G: cant not change the PC RGB mode settings anymore

Hello,
I have a problem with my (pretty old) 23WL56G: I changed some settings in the PC RGB mode and due to that I cant not change the settings any more (the image is flickering and the menu is closing itself any seconds)
Q: Is der any method to factory reset the tv ?
There is no menu entry for this so there is probably some code I can enter in the menu ? (or some button combination I have to press ?)
Thanks in advance

The TV is really pretty old since there are no info in the internet about this model.
I assume such old TV did not support an reset functionality. Sorry but any other method isnt known to me. I dont even known what you have changed exactly
So this looks like searching for the famous needle in the haystack. :(

Limit Color Pallet in RGB Mode

Is there a way to limit the amount of colors available for use in RGB mode? I know that in Indexed Mode, you can limit it to, say, 256 colors, but then so many of Photoshop's features aren't enabled anymore.
Can the color pallet in RGB mode be limited to 256 colors (or any amount of colors we choose)?

Good idea. But the problem is when mixing those two colors together using the mixer brush - it then utilizes the millions of colors in the RGB pallet to smoothly blend those 2 colors together.
If the pallet was restricted to 256 for example, then when using the mixer brush to blend, I'm guessing the blend would appear more pixellated because of the restriction on the amount of colors.
To answer my own question however, I tried adding a Posterize adjustment layer on the very top of the layer stack, then reducing the number of levels to somewhere between 10-15 levels.
It seems to be acheiving what I'm looking for, although I was hoping for a native way to restrict the color pallet without having to use adjustment layers

Folders on NAS/Fileserver disappear for some time in Finder

Hi there,
from time to time in Finder, being connected via afp to an external system, folders disappear for a while or until network drive is remounted. There is no data loss, one or also more folders just get invisible for a while...
I could not figure out clear reproduction steps yet. Eg. reducing Umlauts or slashes didn't solve the issue. Also it happens with different folders.
Any ideas how to further research or even solve this issue?
Many thanks!

ALL the Icons disappear for seconds after using five-finger-gesture and swipe to another page in the home screen

Hello,
iPad Air, 8.1.2
This issue has been making me annoyed for a long time...
You can find the bug by following steps:
1). Go to Settings APP.
2). Use five-finger-gesture to close this APP, and quickly swipe to another page of home screen before the icons in the current page haven't dropped down.( I mean...The animation that likes icons dropping down)
3). You can see ALL the icons will disappear for seconds.
I've restored the firmware again and again, but it doesn't helped at all...
And if I turn on the "reduce motion" option, the icons won't disappear.
And...Some little bugs:
1) In APP switcher, when swiping up to close APPs, the icon's animation is lost. (I mean...The icons shouldn't disappear without any animations. In iOS7, the icons should have a "closing animation"
2)In lock screen, press the power button with a very high speed, and you will see the "time" in the lock screen is being appeared and disappeared, appeared and disappeared, appeared and disappeared...
I hope you can understand me, I'm sorry for my bad English, I'm a middle school student in China, and I have to report these bugs.

I am not seeing that problem, however, this is a user forum. You aren't talking to Apple here.
if you want to report a problem to Apple use this: http://www.apple.com/feedback/ipad.html

I am having a rendering issue where some of my layers will disappear for one single frame.

Whenever I render my comp, some of my layers disappear for a frame or two then they come back. When the frames are gone they give a black flicker effect. This seems like a render issue because in my RAM preview it works perfectly fin. Any thoughts?

Nobody can tell you anything without proper system info or other technical details like version of AE, a timeline screenshot, render settings and so on. I doubt that there is a technical issue, you simply mess up your framerates and have keyframes set in such a way that when a different framerate is used, the temporal sampling is hitting blank spaces.
