Screen Sharing Observe Quality

I found on a few web site a handy tip to change the quality of screen sharing. The tip says that opening terminal and typing:
defaults write com.apple.ScreenSharing controlObserveQuality #
Where # is the quality of the screen sharing: 1=black and white, 2=grey scale, 3=8 bit color, 4=16 bit color, 5 = full color
I've tried this with ichat 5.0.3, but it doesn't seem to work. I still get full quality even if I set it to:
defaults write com.apple.ScreenSharing controlObserveQuality 1
Any help here?
Thanks,
D

Opps,
Just spotted something
defaults write com.apple.ScreenSharing controlObserveQuality #
This s not an iChat setting. It is not a .plist to do with iChat
Most likely it is the setting for the Screen Sharing App. (see System Preferences > Sharing)
The app can be invoked by going to the Go Menu in the Finder > GO to Server and starting the line with VNC:// (Instead of SMB or AFP)
The app that runs this is "hidden" in /System/Library/CoreServices and not in the Applications folder.
I take it this was the Hint ? (which says it is VNC connections = plain Screen Sharing).

Leopard Screen Sharing (VNC) Quality?

Before Leopard I used to use Vine VNC Server for accessing my Mac over the internet. Now that Leopard has its own VNC (Screen Sharing) server built in theres no need to use it.
Normally when I VNC'ed to my Mac over the internet using UltraVNC on Windows it would automatically select the best image compression/quality (eg only displaying 256 colors only etc) to make it much quicker over the internet.
But the new Leopard VNC server only seems to allow full quality screen sharing, which is painfully slow over the internet (esp as my macs running at 1600x1500!), selecting anything other than Auto in UltraVNC will instantly disconnect after entering my VNC password.
Does Leopard's VNC (Screen Sharing) support compression/image quality like Vine VNC? If so how do you enable it?
Thanks for any help!

Thats what I thought as well, the "Allow control" option in ARD admin prefs is off. When ARD admin is not launched VNC to the computer works fine. If ARD admin is opened I can no longer VNC to it. Its like the "Allow control" pref doesn't actually do anything & instead is forced on always

IChat screen sharing dreadful quality

I remember when Leopard first launched this feature was great - it used my full internet connection speed and hence displayed in high resolution. At some point all that changed and it now seems limited to around 80kbps in both directions and i've checked this on several Macs on different networks and ISPs. I can be having a video chat at 800kbps in both directions and see it drop to 80kbps the moment a screen sharing session is started. At this low resolution it really isn't possible to 'collaborate' on image based projects. I wonder, is this speed generic to everyone? I have Apple Remote Desktop to fall back on but Screen Sharing is very convenient.

On the basis a Screen Share is an Audio Chat+ as it were 80kbps sounds very reasonable.
What speeds do you get in an Audio Only chat ?

Screen sharing image quality issue

When I share my screen with another participant the picture/image (screen) quality is so poor that the other participant cannot read the text on his/her screen.
Is there any way to configure the Skype to improve the quality?
If not can we get an answer from Microsoft representative on when we can expect an improvement? The picture quality is significantly worse than other services (e.g. join dot me).
Thank you for your responses.

Hi kerojarun,
I am using version 6.11.0.102 (latest) with Windows 8 on a desktop (HP) as the sharing party and Surface RT and Surface Pro on the recepient side. I shared both desktop and window with the same results. Network speed should not be an issue as video and audio quality is normal and these type of communication methods are more sensitive to a network quality (not just speed) than a static content (image of text).
If I have to I will test with multiple computers and networks. I just expect better support from Microsoft as the quality is significantly worse than join.me in the same environment and conditions.
If I may ask can you test in your environment and compare Skype vs join.me? You will see the image (text) quality difference for yourself.
I really want Microsoft to improve this feature in Skype so users do not have to use another product (e.g. join.me) for content/web/application sharing.
Regards,
Zbysek

Start Screen Sharing Connection in Observe Mode?

Hi,
I've been able to add the toolbar button to switch screen sharing between the control and observe modes using tips I've found around the web.
I need to be able to check on what's going on with one of the computers on my home network without taking control of the mouse and keyboard.
Screen sharing defaults to control mode on connection, does anyone know if there's a way to make it default to observe or if not then to start a specific connection in observe?
TIA,
Rob.

Screen Sharing and Sleeping Mac Mini

Hi,
After months of nagging from my IT colleagues I have just bought a Mac mini, just upgraded to Leopard and am just getting to grips with how it functions. (very impressed to date now I have a "proper operting system" :o) )I am using it in my lounge connected to my Plasma TV. I have enabled Screeen sharing and can access it succesfully from my windows machines using VNC viewer free edition. The colour and picture quality is excellent however it won't allow me to connect when the machine is asleep. I also have Vine VNC server which I am sure would go to sleep and let me connect using VNC however it doens't seem to sleep with Vine anymore and I also get two icons appear in the dock. The screen quality appear to be much better with Screen sharing so I'd rather use that than Vine. I could switch sleeping off howevere I don't use the Mac and would like to let it sleep. I was a bit nervous about posting here for the first time incase I get "abuse" but my other Mac users assure somebody will know the answer. I have some other questions so I'll post these on the site in the relevent areas now I'm registered.
Cheers in advance.
Clarkerz

Clarkerz...Wondering the same thing. No "abuse" from my direction. This is a great question I am also trying to find a solution for.
I often work remotely between my home office work horse (g4 tower) and my 17" MacBook Pro. Files are often duplicated between the systems...and having one access point (screen sharing) is great. However, I am wondering the same thing. I hate to leave the slave computer (in most cases this is my G4 tower) on permanently in the event I happen to need to share in.
Before Leopard, I was using Astro View / Share. I am sure some will wonder...why that program. Well, long story short, pain in the arse, but it worked...althoughbeit not as well as Leopards built in screen share. Though Screen Share is a much better solution...I still wonder about the "sleep" issue. Hate to leave it on permanently.

Screen Sharing and Video Chat

Hi! I have 2 computers right next to eachother, and I felt like testing out the new Video Effects and Screen Sharing abilities of Leopard.
So, I logged on to each of the computers in iChat (with 2 different accounts), and attempted to do this. However, whenever I attempt to Video Conference or Share Screen, I get an error, saying the other person (the one that accepted the request), cancelled the conference.
So what's up with that?!
I am sorry if this isn't clear, and I will post back with any additional info you need.
Thanks!

iChat requirements
* Audio chats require a microphone and a 56-Kbps Internet connection.
* Video chats require an iSight camera (built-in or external), USB video class (UVC) camera, or FireWire DV camcorder; and 128-Kbps upstream and downstream Internet connection.
* Photo Booth and backdrop effects require an Intel Core Duo or faster processor.
* Backdrop effects when using a DV camcorder require fixed focus, exposure, and white balance.
* Some iChat features offer better performance and quality with higher system capabilities.

Screen Sharing and VPN functionality with ARD

Can somebody with ARD tell me if the following setup is going to work? There's no demo version so I can't tell if it's going to be worth 300 dollars.
I have a number of local machines in a network and a couple external machines in other parts of the state that VPN in to the network. I want to be able to have a local machine that can screen share w/ voice reliably with these guys.
"Reliably" being the key. iChat screen sharing and VNC alternatives do not work reliably at all. They crash, they are slow, they sometimes disconnect video and keep the audio. Or some days they work perfectly, but that's few and far between. Zero-conf services like MacHelpMate work just fine, but I'm reluctant to pay 600 a year for something like this.
Is ARD going to be able to be able to fix this problem for me, or am I really just going to end up with more of the same issues?

ARD uses VNC for observation and control, so if you're having problems with iChat screen sharing and with VNC clients, I would not expect that ARD would be any better. My suspicion is that your network and/or VPN are cutting things off, since most people have found iChat sharing and VNC to be pretty reliable, but without being able to perform reliability tests on your network to VPN clients, I can't say for sure.

Remote desktop and screen sharing with RMI

Iam developing an application for screen sharing and remote desktop
the problem is a performance problem
in the screen sharing application server screen is captured and the image is sent to all connected clients through rmi connection
I used JPEGImageEncoder to compress the image and convert it to array of bytes
then zipped the resulted array using deflater.
the result is sent through rmi connection
the performance is so poor
i tried JMF but the performance is worse
i am thinking of a way to send the server screen only if it is changed but i don't know how
anyone could help me to enhance it with acceptable quality for the image
thanks

As you said, you need to only send the changes over the line.
Java can not tell you what has changed, so you need to either write some JNI, or do a check on the current image, with the last image. (this would eat quite a bit of CPU time on the server).
It might be worth looking at the source for VNC, and other simler products.
The simpliest solution would be to split the image into blocks of x by y pixels, then do a pixel-by-pixel check on that block, and only send the block if it has changed.
Next thing to think about is scrapping RMI, and using raw sockets. RMI has a fair sized overhead.
Zipping a JPEG is unlikely to have any effect. A JPEG is already compressed.
You might want to look at a lossless compression format, like PNG, as the JPEG will have articles. This might be acceptable. If so, changing the compression ratio of the JPEG might be an option.
Finally, the bottle neck might be the call to Robot.createScreenCapture. This is not the fastest method.

How to set Screen Sharing to greyscale on Leopard 10.5

The new screen sharing feature (just a built in VNC client) is decent, although I would've liked it better if it gave an option to view the connected computer in greyscale (like Apple Remote Desktop can), so as to make the screen redrawing much quicker. This is how you do that:
To change this setting manually, open up the Terminal and type in the following command:
defaults write com.apple.ScreenSharing controlObserveQuality 2
This changes the controlObserveQuality setting within this plist file: “~/Library/Preferences/com.apple.ScreenSharing.plist” file to 2, which is grey scale. To change it to a different resolution, substitute the number 2 with one of the following numbers:
1 = black and white
2 = grey scale
3 = 8 bit color
4 = 16 bit color
5 = full color
However, when you've connected and you're all happy that you have greyscale, if you then choose Adaptive Quality from the View menu in Screen Sharing, this will set the default back to 3 (8 bit color), and you'll have to run the Terminal command or edit the .plist file again - so, just leave it when you initially set it and all will be well!
----

I tried the malisphoto.com solution it but it didn't work for me.
I even tried the one at entropy.com but that also didn't work.
I was very careful and successful in the command line (bash) and afterwards, phpInfo() showed that the GD library was installed, however, my localhost GD (gif draw) scripts still kept showing the same old error messages on my localhost (and not online): "Fatal error: Call to undefined function imagecreatefromgif()"
Perhaps I'm just wrong to think PHP GD will work on my localhost pages after performing these installations - perhaps I'm misunderstanding something? Am I'm trying to change a light-bulb with a jack-hammer?
I should also point out that both solutions made my localhost run extremely slow. After restoring my system, it's all working fine (but without php GD).
My system is a Power Mac 10.5.8 Leopard
This is really lame. Is Apple trying to shut out PHP now? Is PHP the new "Flash"?

Screen sharing to OS X Lion Server with non-admin account

I have set up a Lion Server with one admin (in addition to the root user) and several non-admin normal accounts. In Server.app, I have enabled remote login with ssh, and remote management via screen sharing. I am unable to use Screen Sharing to connect to the server from the non-admin accounts, but able to use the admin account. I've read that it is only enabled for admin users, but need to access from non-admin accounts, and I can't add these accounts to the admin group. Is there a way to do this with Workgroup Manager? I tried changing the Remote Management settings in System Preferences by adding the non-admin, but when selecting 'Observe' and 'Control' in the options for the user, they are not saved.

I resolved this issue by deselecting the "Enable screen sharing and remote management" in Server.app and going to System Preferences, Sharing Preferences, Screen Sharing, and allowing access for "All Users". If you have some users you want to allow VNC, you can create a group, add the allowed users to the group, and add the group under "Only these users".

Photos in 9.2 do not appear when viewed through screen sharing

I recently upgraded my Mac Mini, which stores my master iPhoto library, to iPhoto 9.2. Because this Mac Mini is also used as a media server for an AppleTV, I almost always operate the computer through screen sharing using a MacBook Pro, rather than connecting it to a television. Both computers are running OS 10.6.8.
Since upgrading this setup to iPhoto 9.2, I can no longer view photos in my iPhoto library through screen sharing. Previously, I had noticed that I could not view certain other things through screen sharing (such as watching DVD's). For example, I couldn't view individual photos in detail in iPhoto, but I could view them in grid view. Now I cannot even view them in grid view anymore.
Is there a graphics library that is not compatible with screen sharing that is now being completely used by iPhoto? Is there a setting that I can check? Any help would be greatly appreciated.

Thanks, Michael.
I will give it a try.

Screen sharing performanace differences on MAC and WINDOWS

Hi All
I am having a big issue of screen share latency (working on WINDOWS) which is about to 20 - 30 sec sometime and 10 - 15 sec in general. I was thinking that It could be because of my network limits but when on the same time and in the same network I publish my screen share from MAC, miracle is happening, there is unexpected difference and there is no latency and if there, it is sometimes about 2-3 sec hardly. My maximum users are using WINDOWS and so that I am searching a solution for this latency problem. Please suggest a solution.
Thanks.

Hi Raff,
We have tested it on following combinations on port 443 , sending and receiving.
1. Screen sharing on MAC machine on LAN (Result: Good speed of sharing)
2. Screen sharing on MAC machine on WiFi (Result: Good speed of sharing)
3 Screen sharing on Windows machine on LAN (Result: Too much Latency in receiving)
4 Screen sharing on Windows machine on WiFi (Result: Too much Latency in receiving)
Specially we have noted on windows that after some time , data from windows machine (Any windows machine) screensharing addin process stop sending any significant upstream data(used netlimiter to verify this) , so reciver receives almost nothing or very delayed screen updates.
I tried to figure out using Wireshark , but not sure that which packet to look for which can cause issues.I do not see any dropped packets atleast in packet scan.But packet sending speed decreases after some time on Windows machine.
We use same settings of performance ,Quality ,Fps and Keyframes on Windows and MAC while sharing screen.
What to look in for wireshark.
Your inputs will be very helpfull.

Screen sharing to windows xp

hi i was looking on the system preferences and i found out that i can screen share on my local network but i am not sure exactly how to. if anyone knows how to please help me. thanks

I am able to get the VNC connection from XP (UltraVNC) to the Mac (with Screen Sharing enabled). The connection only works at the highest screen quality (select AUTO settings under the Quick Options in ultra).
My problem is that I'm trying to connect with a lower resolution to improve speed/refresh, since I'm connecting through the ether and not on a LAN. Anyone figured out how to connect with 16, 64, or 256 colors from UltraVNC?

Script to start and stop screen sharing

I've had no luck finding an applescript that will launch system preferences and select screen sharing in the sharing tab. I want to use this as a rule in Mail so I can open screen sharing and subsequently close after use with Jaadu on my iphone for only the time while I want to access my home computer.
Is there anyone skilled at writing that for me?
Thanks,
Michelle

ARD has four main components:
1) ARD Helper
2) ARD Agent & associated daemons
3) ARD Menu Extra (controlled by the SystemUIServer)
4) ARD Admin Console (if you have an Administrator license)
What this script does:
1) Any running ARD components will be stopped as needed. For example,
they'll be stopped before an uninstall, reinstall, or restart
request. They will not be restarted unless you specify the
-restart options.
2) Components will be restarted as required. For example, restarting
the administrator console forces a restart of the agent.
Restarting the agent, in turn, forces a restart of the helper.
3) If you -uninstall but don't specify a new installer to run, then
the -restart family of switches will be ignored.
4) Options can be specified in any order, but remember that the
options are ignored unless their parent options are specified. For
example, -package is ignored unless -install is specified.
RUNNING THIS SCRIPT FROM A GUI
You can make yourself a GUI-based kickstarter program to run this
script if you like. The options, set in the console, can be conveyed
via environment variables to this script, per a spec shown in the
source code for this script (or the traditional way using command-line
switches). Be sure the console application runs this script with sudo
privileges. The console should also specify its own location in the
APP environment variable, and may specify the location of a
STRINGS_FILE to use to load string definitions for any localizable
messages produced by this script.
A GUI console could stay up & running between runs of the script but
should avoid running multiple instances of this script at the same
time.
WARNING
This script can be used to grant very permissive incoming access
permissions. Do not use the -activate and -configure features unless
you know exactly what you're doing.
