I'm having trouble with video tearing (vertical sync? or maybe not, unsure) after an upgrade.
The system used to work flawlessly, using gentoo-sources-2.6.16-r4 and ivtv-0.6.4 and mythtv 0.20_p12325. I'm running a hauppauge PVR-150. I just upgraded to gentoo-sources-2.6.19-r4 / ivtv-0.9.1 / mythtv 0.20_p12376 If I setup ivtvctl/v4l2-cfg settings manually and run "mplayer /dev/video0" it works great, I see clean stable video, and I can change the channels by command line. But as soon as I run mythbackend, the video in mythfrontend tears pretty badly... some black-and-white comes in clear, but most of it gets trashed. If I then stop mythbackend, and revert back to "mplayer /dev/video0" it still tears... and the problem persists until I reboot. Technically I suppose this is a mythtv configuration or integration problem, not a problem in ivtv. But clearly mythtv is setting something in the ivtv module that is causing this to happen. I hoped you guys might recognize it. Thanks. -Mike PS: PAL-BGH, New Zealand. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
