[AG-TECH] Full Screen Vic

[Barz Hsu]

Hi All,

There is another solution.
Currently, most of graphic cards support hardware scaling and color
conversion.
As presented in SC Global 2004,
we have modified vic to support XFree86 Xvideo extension such that
full screen mode becomes more efficient.
(ps: 1: double click the window to trigger full screen mode
    2: scaling the boundary to resize viewing windows )

You can download source code and binary from htt://vic.nchc.org.tw

Another solution would be to use a hardware scan converter with a zoom
function.  That way you can zoom in on any window of any application
on your desktop and only output the actual video playback sans
widgets.  I've used the Averkey products in the past:
http://www.aver.com/products/comptv_AVerKey550.shtml

I do prefer direct out from a video card's s-video for color
saturation and clarity, but that isn't always feasible.

Also the Nvidia cards have an overlay option in Windows, so that any
app using video overlay goes full-screen on your s-video output.

Cheers.
