the ComputerEyes Media Vision RT driver is in the "pub/FreeBSD/incoming"
directory on wcarchive.cdrom.com. there is also a version nv that uses
the driver in the same directory (ls *mft*). as my standard disclaimer
the Computer Eyes Media Vision RT board that has a driver is the interuptless
and does not map the frame buffer to I/O space. all 3 bytes by 512x480 pixel
must be read through an I/O port and the is SLOW (20 seconds 386/25MHz, a
couple seconds pentium/90 MHz) -- defintely not real time. it does work
good for MBONE conferencing tools (such as nv) or Web frame grabber. halfing
the interlace and skipping a pixel could cut these times by about 3.
