<DIV><FONT face=Arial size=2>Hi Galen!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>> Your graphics card isn't likely to make the video look any
better.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>What about hadware accelerated decoding, motion
adaptive deinterlacing and GPU shader based filtering/compositing??</FONT></DIV>
<DIV><FONT face=Arial size=2>One very simple thing - as far as I know there is
no way of high quality image rezising even with things like MMX - today I only
know GPU accelerated applications that can do this...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>>The only real reason you'd use the video card is if you can't play the
video properly (i.e. it skips or stutters because your >CPU isn't fast
enough) and hence need to reduce CPU usage - this is hardware
acceleration.</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I have a GPU, I don't want to waste my CPU time
with video tasks...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Without an hardware accelerated overlay surface
none of todays CPU's can deal with high definition video.</FONT></DIV>
<DIV><FONT face=Arial size=2>And even with - ever tryed to play a HD 1080p H.264
stream with 50MBit/s data rate (ever thought about e-Cinema
requirements)?? - don't try this with VLC - no multi processor support
like the Quicktime Player and no GPU support like Windows Media Player or
commercial HD-DVD-Player software ;-)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Ok - I know about the problems of supporting GPU
features like H.264 decoding - but support of multible CPU's at least would be
great... but imho the most faszinating possibilities are located around GPU
shaders - color correction - denoise - compositing...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>only some thought about the future of video
processing...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>best regards</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Danko</FONT></DIV>

<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>Look at the video output options under VLC's preferences. If you're using
Linux, make sure you have your video drivers setup properly - if you you
don't, or your card doesn't support the modes you're trying to output, VLC
will give errors or simply quit. </DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>Under Linux, see if you can use XvMC or OpenGL video output. XvMC is
fastest, as it uses hardware motion compensation for a performance increase.
OpenGL (if I recall) only uses your card for colorspace conversion.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>As for Windows, I don't use Windows, but I believe the basic idea is the
same - try different video output modules in the preferences.</DIV>
