VDPAU + live TV ...image shifts down-right by 1 pixel each channel change

Reported by: Ronald Frazier <ron@…> Owned by: markk
Priority: minor Milestone: 0.23
Component: MythTV - Video Playback Version: unknown
Severity: medium Keywords:
Cc: Ticket locked: no


When watching Live TV on VDPAU cards using a VDPAU profile, the image shifts down/right by 1 pixel per channel change. On some TVs you don't notice this until you've changed channels 30 or more times (due to overscan). On my aquos you see it right away. There is a single pixel line at the top and left of the screen. Everytime you change the channel, the image shifts downright and the line at the top and left gets 1 pixel larger. The problem does not occur if I switch to a non-VDPAU profile. It does not occur on prerecorded content or when playing videos. Changing the theme or OSD doesn't help either.

I'm running 0.22 fixes with the 190.53 drivers on a G210 card.

I can't reproduce this with a variety of settings on 2 different frontends with trunk. If there was an issue it may have been resolved with the newer VDPAU code.
