Post subject: | ivtv / pvr150 picture quality |
Hello! I installed ivtv 0.3.6n and KnoppMyth yesterday and after a lot of problems it finally work well, but: The quality of pvr150 output is bad. The picture is blurred. It looks as if the picture is present twice but shifted by 2-3 scan lines vertically and merged together, so when i should describe it correctly i'd have to say: Its only vertically blurred. Horizonzal everything is fine and sharp ![]() I think it would look similar when the interlaced fields (odd/even) are swapped and deinterlaced afterwards, but thats just an assumption. The tuner type is set correctly (idx 97 - tuner type 55 = LG PAL (TAPE Series)), also the tv standard is correct (PAL) but also when using ptune-ui.pl and mplayer /dev/video0 the problem is still present. Does anybody have an idea how i can solve this problem? I know that it does not apply to MythTv but i think a lot of people here know ivtv and its problems. Best regards, Kai |

Generally, if you want to use the dev version ivtv, you should be subscribed to the ivtv-dev list. I suspect this thread might help (you'll want to add the command to set_ivtv_params: http://www.gossamer-threads.com/lists/i ... ctl;#21404 (specifically, the 'ivtvctl -c dnr_temporal=0' command) -brendan |
