Native live viewer for better performance

[graemian]

Hi all,

Yesterday I saw a Windows app that could show a 25fps+ live view of 16 analog cameras.

My understanding of ZoneMinder tells me this is going to be difficult to match. I imagine the Windows software is using some hardware tricks to achieve this (i.e. copying image data from the capture card directly to the video card). Obviously this would only work on the PC with the capture card, but it is pretty cool none-the-less.

Would it be possible to use ordinary ZoneMinder for recording and playing, but augment it with a kick-ass native live viewer?

Does anyone have any experience with this? Any pointers would be much appreciated.

Thanks,
Graeme

There are already I think a few people here on the forum attempting to build such an application. It's been on a few peoples wish list for some time. Just need someone that knows how to pull the images from the buffer and design the application.

In theory it should be pretty easy and just a case of mapping the images in shared memory to the video memory which should be really quick as they will already be in the right format.

I'm not really an X gui type of guy though otherwise I'd have done it already. My windows (with a small 'w') applications are limited to Perl/Tk I'm afraid which probably isn't much use.
