I'm having what appears to be an interlacing problem with my LML33 capture
card, particularly when displaying in overlay mode in Xawtv. It seems like
the overlay is only getting half of the lines of the image, the other half
remain blank unless I fiddle with the TopField bit in /proc/zoran0. I'm
capturing from a video camera running on the Composite port. Resizing the
xawtv window doesn't have any effect, unless I shrink it to the point where
the other half of the lines aren't displayed... :-)
When capturing to a file using lavrec and viewing the results on another
machine, the image is complete but there seems to be quite a lag between
updates of the odd and even lines - ie. if I move my hand back and forth at
a reasonably slow rate I can see the afterimage of my hand persist on one or
other set of lines when I switch directions.
I am using latest driver-zoran (v0.9.2) from CVS, though I was experiencing
the same issues with the previous version. I don't experience these image
quality issue with the 2.4.20 kernel LML33 driver (zr36067.o), but it seems
to have an 'in use' counter bug that prevents me from viewing the source
with xawtv and recording using lavrec at more than one time.
Anyways, I'm up for any suggestions.
Thanks in advance.
----
echo TopField=1 > /proc/zoran0 - No change
echo TopField=0 > /proc/zoran0 - Causes 'ghost image'
any more flipping of TopField after this point just causes the odd or even
lines to persist with the image being displayed at the time it's flipped.
modifying DupFld - No change either way
