<b>radeon_vid</b> provides support for the <b>BackEnd Scaler</b> on ATI <b>Radeon</b> chipsets.
It was designed and introduced as analog of <a href="video.html#2.3.1.7">mga_vid</a> driver, so you can use it in the same way!<br>
But main goal of this driver usage is <a href="video.html#2.3.1.12">VESA</a> driver.<br>
Simply because VESA enables TV-out on ATI's card but Backend scaler is used after
mode switching. This implementation outputs video stream on both: <b>TV-screen</b> and <b>CRTC</b>
display simultaneously. (It slightly degrades quality of video output but it's
much better than nothing).
Sorry! I couldn't find out any video overlay's related information
on ATI pages. (I planned to implement it through <b>int 10h</b> calls). But it was
very easy to implement this stuff through reading/writing Radeon ports.
<br><b>NOTE</b>: XXX_VID technology is perfectly undocumented and maybe in the
future this stuff will be fully rewritten. This is the first public release of
driver.</P>

</P>
<P><b>Limitations:</b> Currently it works only with <b>YUY2</b> format, so use the DirectShow codec
family with it. You should have at least 32MB of video memory.<br>
<b>Conclusion:</b> I know there are lot of lacks and bugs. So if you are able
to improve something then simply send me your patches.
