UltraVnc screen recorder

What's the difference with other screen recorders

There exist a lot of screen recorders, but all lack the speed for doing some full screen recording. The speed is just to low or cpu to high.
Online compression can only be done with some real-time disk eating codecs....
Even the 300$ cam... studio is slow.

As i needed something faster to make some manuals, i found it quite similar to the speed problem that VNC has.
I guess most screen recorders use the same vnc capturing method under the hood.
Integrating the mirror driver was a real speed boost, 1280x1024x15Fps + online divx compression

UltraVnc screen recorder looks similar camstudio

The screen recorder is build with the old Rendersoft camstudio source, we didn't wrote the whole thing ourself.
We just removed and added some code to make it faster.
The about box give the acknowledgment to the original creators.

There was some discussion about the old RenderSoft License.
The website mentioned GPL, while the license.txt included in the source distribution was a BSD style license.
Non of the GPL requirements ( http://www.gnu.org/licenses/gpl-howto.html) where fulfilled, so we will use the included written license
