Re: [ivtv-devel] Settings for scenes with high motion

[Peter L. <pe...@la...>]

NTSC.  I'm not using matroxfb, but I'm using directfb.  I use mplayer 
-vo dfbmga:fieldparity=top:buffermode=triple -fs -cache 8192 -autosync 
30 $FILENAME

The most influential factor is the fieldparity option.  If that's 
wrong, the video looks aweful because the interlaced frames get drawn 
in the wrong order.  The autosync 30 seems to have a lot to do with how 
good the video looks.  I can't remember what it does exactly, but I get 
choppy video when it's too low.

"To announce that there must be no criticism of the President, or that 
we are to stand by the President, right or wrong, is not only 
unpatriotic and servile, but is morally treasonable to the American 
public."
