[linuxtv-softmpeg] Re: Chroma artifacting
Hi,
I haven't noticed this problem on a CLE266, but then again I've only been
using the TV output so haven't been looking too critically. I have noticed a
sort of judder on the picture sometimes - the picture sometimes jumps up and
down a line occasionally. Might be a similar problem.

I think that softmpeg does turn on de-interlacing.
Search for the line:
dlc.options = (dldesc.caps & DLCAPS_DEINTERLACING) ?
DLOP_DEINTERLACING : DLOP_NONE;
in v_directfb.c (or in video.c if you're not using the latest CVS code) and
change it to
dlc.options = DLOP_NONE;
... to keep an interlaced picture.
I assume that the Matrox driver does deinterlacing.
Hope this helps,
Colin
