I'm having the same problems.
At some point I was able to hit the "allow" button and then twitcam said "the camara is in use" (by another application) but is not true. Only sound get broadcasted.
The same thing happened to me using http://livestream.com.

Can't get JNI_CreateJavaVM to work on linux

i am using linux redhat 7.1 and jdk1.3.1_02 and i cannot get past the JNI_CreateJavaVM call. this same code works fine under windows.
here's my code snippet:
#include <stdio.h>#include <memory.h>
#define NUMBER_OF_JVM_OPTIONS 2
static STRING_UTF8 CLASS_PATH = "-Djava.class.path=/usr/local/LPDProgress/LPDProgress.jar:";
static STRING_UTF8 SECURITY_POLICY = "-Djava.security.policy=/usr/local/LPDProgress/LPDProgress.policy";
JavaVM*           jvm = NULL;
JNIEnv*           env = NULL;
int JNI_Init ( void )
JavaVMInitArgs jvmArgs;
JavaVMOption    jvmOptions[NUMBER_OF_JVM_OPTIONS];
int rc;
if (jvm == NULL)
    memset(&jvmArgs, 0, sizeof(jvmArgs));
    jvmArgs.version = JNI_VERSION_1_2;
    jvmArgs.ignoreUnrecognized = TRUE;
    JNI_GetDefaultJavaVMInitArgs(&jvmArgs);
    jvmOptions[0].optionString = SECURITY_POLICY;
    jvmOptions[1].optionString = CLASS_PATH;
    jvmArgs.nOptions = NUMBER_OF_JVM_OPTIONS;
    jvmArgs.options = jvmOptions;
    rc = JNI_CreateJavaVM(&jvm, (void**) &env, &jvmArgs);
    if (rc == JNI_ERR)
      jvm = NULL;
      printf("Error creating JVM.\n");
      return 0;
... snip ...I never return from the JNI_CreateJavaVM call. it core dumps with green_threads and "hangs" with native_threads.
here's my build script:
#! /bin/bash

Can't get X to work properly (ATI AIW 9800)

Hello,
I have a few problems. My first problem is this. The dpi was messed up when i first install, so i thought no big deal, I'll just go and configure the defaultserverargs setting in the startx script to "-dpi 75". This does not seem to work. Secondly,I can't get gnome to work as my default window manager. I put this line in my .xinitrc file in my home directory:
exec gnome-session
I also tried this:
exec /opt/gnome/bin/gnome-session
My last problem is that when i try to install the ati fglrx drivers with the stock kernel arch package but whenever the fglrx module is called, it says that the module doesn't exist. One thing i might mension which might be of importance is that i compiled a custom kernel during install without SMP and preemtivity so i could use my rt2500 wireless card. Thanks in advance for the help
cheers,
-Lukas

sinisterguy: You're going to need to build your own kernel module, afaik you can't just symlink a module built for another kernel and expect it to work.
As root, run
abs
Once that's done (it'll check out a bunch of stuff from cvs), change to your normal user and either make a directory for the new package, or cd to some temp directory, then:
cp /var/abs/extra/modules/ati-drivers-arch/* .
vim PKGBUILD
then make the following changes:
pkgname=ati-drivers-arch
to
pkgname=ati-drivers-custom
(or whatever you want to call the package)
depends=('ati-drivers' 'kernel26')
to
depends=('ati-drivers')
source=(https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/fglrx_6_8_0-$pkgver-1.i386.rpm fireglcontrol.desktop)
to
source=(http://www2.ati.com/drivers/linux/fglrx_6_8_0-$pkgver-1.i386.rpm fireglcontrol.desktop)
(for some reason I can never get the source from the https address through makepkg.)
and
_kernel=2.6.15-ARCH
to
_kernel=`uname -r`
Save and quit, then run
makepkg
- this'll make you a brand new kernel module package that you can install with
pacman -A ati-drivers-custom-8.22.5-2.pkg.tar.gz
You'll need to update this package every update to the ati-drivers in the same way you originally built it.
If you need more information, ABS is a good place to look, as well as man makepkg.

Can't get sound to work [SOLVED]

Hi, I'm new to arch/linux in general. Built a computer, and can't get sound to work. I ran Ubuntu for a short period of time, and sound worked there, so I'm assuming there's no hardware issue here.
I'm a little bit stuck as to what I should be doing. Help?

Start with the wiki: https://wiki.archlinux.org/index.php/Ad … chitecture
If you still can't figure it out and you want help, at least post some info, instead of 'can't get it to work' (this implies that you tried something, but what?).

Have entrourage and want to use Mail. Can't get it to work.

I had a macbook and purchased the Microsoft office for Mac which included Entrourage.
I have now purchased a new macbook Pro and want to begin to use Mail rather than Entrourage.

I am on Charter.net at my office and sbcglobal.net at home.
How can i get this to work. I can receive on Mail, but i can't send.

check your outgoing port settings and make sure it's using a specific port and not the default port, also you might want to check to see if it is using SSL, TLS or any other encryption. Verify the setting from your old machine setup.

If it's showing the red disabled screen due to incorrect passcodes then you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 - you should then be able to reset the iPad via your computer's iTunes and restore/resync your content to it

Hi,
Is there an iPhone involved ?
If not, what happens if you remove the Apple ID on the iPad and then set it in Airplane Mode (allow a couple of minutes at this point) followed by re-adding the Apple ID ?
What, if any error messages are appearing on the Mac when you try to launch the App or Login to the iMessages server ?
Is the Apple ID linked to an iCloud account ?

I bought an IR receiver and an Apple Remote, and I can't get it to work. What am I doing wrong?

I bought an IR receiver and an Apple Remote, and I can't get it to work. What am I doing wrong? The receiver is a Lenovo eHome OVU430006/01 USB IR Receiver.

Hello,
You would need to pair the Apple Remote with the receiver. So I would use the generic Mac/PC receiver and follow these instructions:
http://support.apple.com/kb/HT1619
If that doesn't work then check in System Profiler to see if the IR receiver has been recognized by the PowerBook's hardware. You may require the install of drivers for this device to be recognized.
Best of luck

Try turning the email account off and then turn it on again. Settings>Mail, Contacts, Calendars>select your gmail account>Off. Go to the mail app and then come back to the account in the settings and turn it on again.
If you can't find any other way for the iPad to accept the password, delete the email account and then add it back onto the iPad.

I have a Mac Mini and I can't get it to work with my Ricoh Aficio MP 161. Any ideas?

The latest Apple driver support begins with the MP 171.
Here is Ricoh's official driver download page specifically for the Afico MP 161. Note that new drivers for this device were released on Aug 2, and include Lion and Mountain Lion.
Hopefully, this will solve your device issues.

My iPhone 5 went black. I tried pushing the on/off button and the circle button at the same time. It worked once and then it happened again and I can't get it to work.

Iphone 5 went black. Tried pushing on/off and circle at the same time. Worked yesterday and then did it again today. Can't get it to work.

You need to hold those button longer until you see the apple logo, then release, then wait for the phone to boot back up.

Best if you try and explain what you are trying to acheive.
Iphoto is a different paradigm than you're used to. I don't understand why you are trying to transfer your edited photos back to an external disk.

Hi Mike,
I've checked your account. I see that you just purchased the subscription this morning. The order is still pending processing, which is why you haven't yet been able to log in an use your subscription. It can take 24-48 hours for a subscription to process fully. Once it does, you'll be able to log in and convert files.
I apologize for the inconvenience.
