General :: Video Conferencing - H.323 Client That Can Broadcast Screen?
Nov 4, 2010
I'm looking for an application for Linux that will connect to an H.323 video conference and allow the user to send their desktop as a video stream, instead of using the image from a webcam. This is for giving presentations, when it is usually more useful to see the speaker's slides than their face.
All I have found so far is Ekiga, but as far as I can see it doesn't offer this facility. Something free would be nice of course, but paid-for software would also be of interest.

I've been trying to find a good solution for this, and so far I've not had much luck. Web-based solutions have been laggy and buggy, and any software solutions seem to be windows-only.
I can set up a server on my machine if needed, but opening ports on all the participants is definitely not an option. Windows compatibility isn't necessary, but a nice-to-have.

I'm running lucid. I have attempted several times to place a video call to Google talk contacts from empathy. The voice works fine and video from party is received successfully, but empathy won't broadcast my video. I know it's not a hardware issue.

I'm currently working on a project to help visually impaired people. We're planning to use Orca screen reader for gnome. Everything is doing great but there is a problem with email web clients the most popular ones(gmail, yahoo, hotmail) are not optimized for screen readers. Is there some kind of simple email client optimized for this? Need to be very simple and straight foward and support multiple users too.40

I sshed to a server a week ago, then ran *screen* and created a few windows in my screen session. I then ran a few programs on those screens. All the programs were running in the background (I run them with &). I did not close or detach from the screen sessions. So I was still connected to those screen sessions from my client machine.
Then, this morning I find my client machine rebooted. When I do screen -ls I find there are no screens available to reattach to. But that is not the worst part. The strange thing is that all my processes (which were running on the server) have disappeared as well, even though they were running in the background. I thought 1) using screen I will be able to re-attach to old screens when my client restarts, 2) If I have sshed to a server and have run programs in the background, restarting the client should not stop those programs (even if I had not used screen).

If I take out the existing video card and put in another one of a different type (but not a different brand), how does Ubuntu behave? I know what Windows typically does. Windows starts up the screen using a default video driver which is at least 1024 by 768 and then asks you what this new bit of hardware is and asks where the drivers are. I'm pretty sure Ubuntu has default drivers of its own, but I don't know what their resolution is.

Is there any way to pipe video from the screen to a video device that can be used as if it came from a webcam? I assume it uses udev somehow...

I'm just wondering if there is a video capturing program that can, at the least record what is on my computer screen (including what is on Wine) and at the most capture what is on my webcam as well.

When # shutdown +5 is run all the terminals (including pseudo terminals) are sent broadcast messages saying system is about to go down. Is it possible for user to receive this in the form of OSD or system tray notification so that he will be informed even if he is not running any terminal emulator or running it but minimized it and working with something else?

Hey I'm looking for something to grab a section of the screen ... like to allow me to drag a rectangle around a portion of the screen and when I release, capture only that -- in to the clipboard would be fine or at that point to a image file format which I could save on the file system.

I just installed Fedora 12 on a rack computer. I know my screen has the ability to show 1600x1200 pixels. But I don't know what my video card can do. Right now my screen is stuck at 800x600. When I had Fedora 11 I remember it could go to 1024x768 or maybe a little larger. I can't really find a driver for the ATI RageXL, How to make the screen resolution as high as possible.

I am looking for a good alternative to Skype. I would like to have video and voice calls with a family member who uses MS XP but would like to avoid Skype if possible. Does anyone know of a good client with good video and voice quality that will work on both platforms. I'd like it to use open standards so at least we can use different OS specific clients if one is not available for both platforms. Googling hasn't yielded much and some of the results refer to really old (~2006) articles or apps. I hope I'm not doomed to using Skype. I've resisted so long with using SIP clients for voice but am stumped now that I want to include video.

I have a fresh install of Fedora 11. All is good except the VNC client. When connected using the client all is fussy or blurred out. The Fedora computer is next to my computer and I can see the movement of the mouse on its screen, but cannot see on VNC viewer. I have tried this from several different computers Windows XP and Windows 2003 and the result is the same.

Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.

I'm looking for a Linux tool that allows me to transcode videos to a video codec that is highly compatible to the Windows platform. We produce large scientific videos from measurements and would like to show those videos during presentations and submit the videos to journals. We want to be as compatible as possible (we can not influence for example the codes installed on the presentation system or on the journal reviewers system).
Virtualdub suggests one of these codecs:
* Radius Cinepak
* Intel Indeo R3.2
* Microsoft Video 1
We tried ffmpeg, mencoder and Virtualdub under wine, none of those tools could produce videos encoded with the aforementioned codecs.
