Finally, I'll have to port it to LynxOS. The SDL Libraries are not avialble for LynxOS. And compilation of SDL on native LynxOS failed. So, is there any alternative? Thanks anyway. -----Original Message----- From: Uday K Verma [mailto:udayv-sA5OA4KG+12fsxuIvKNZIgC/[email protected]] Sent: Thursday, April 08, 2004 12:17 PM To: linux-india-programmers-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org Subject: RE: [LIP] video display Try looking into SDL.

I want to display large images (1920X1200 size) at video rate (30fps). I want to know what the best method of display would be. I am using Qt. I have also tried raw X Window programming, but am unable to achieve this rate for such huge size images. Specifically, these are 2 promising options: 1. MIT's shared memory - it takes almost 150 ms for the XShmCompletionEvent to be received, after using XShmPutImage. Is there any way to improve this? 2. Qt's pixmap display proves to be fast, but it takes a long time to convert my image to the Qt's pixmap format. Any suggestion? Thanks!
