Dear info-performer

I am working at KBS(Korean Broadcasting System) technical research
institute, and I am developing realtime simulation program by using of Onyx
InfinityReality Rack 4XR1000 with 2XRM6 and sirius video board and IRIS
Performer, OpenGL, Video Library.
However, I have found 2 problems as follows.

   < Problems >
    1. Live Video Input process is not realtime.
       I have selected "Live Video Input" menu of /usr/sbin/vcp with analog
       video source with submenu
           - format : Composite
           - Timing : CCIR601 525
           - Genlock Sync : composite input.
        But, the video in window 720x486 is not display with realtime.
        I guess that frame rate is about 15-20Hz (15-20 frames display /sec).
        So we have changed sirius video boards with other ONYX system, but
        video out of Onyx InfinityReality is not also realtime.
  
       Would you tell me the method how to display live video input realtime
       with Onyx InfinityReality.
  
     
    2. I am using of Performer and OpenGL and VL library.
       There are 32 bit and 64 bit mode libraries of Performer and OpenGL.
       But VL library is only 32 bit mode, and there is no 64 bit mode
       library of VL library.
       So, I am compiling simulation program with 32 bit mode now.
     
       How can I use VL library of 64 bit mode?

       Sincerely,
       YOON, YEO CHEON
