So you got the pcHDTV and now the contrast is to high the best would be to use v4lctl to change the contrast on the card:
v4lctl -c /dev/video0 setattr 'contrast' 21500
v4lctl -c /dev/video0 setattr 'chroma agc' on
To test v4lctl:
v4lctl -c /dev/video0 list
but if you are using Fedora core 5 ... this will segement fault (at least with xawtv-20060227-141156)
so to get a similar result you need to put the correct settings in the db, the GREAT thing about mythtv is that it doesnt have a global contrast setting.. so you have to enter this into the db manually:
mysql -u (username) -p mythconverg
at the prompt put:
update channel set contrast=21500,brightness=37500,colour=32768,hue=32768;
update channel set videofilters='adjust=34:253:1.0:23:232:1.0';
if you dont like the results just put in :
update channel set contrast=32768,brightness=32768,colour=32768,hue=32768;
update channel set videofilters='';
to reset it back to the defaults
you are dreamy.
That's awesome, worked beautifully. Thanks Doug!
