You will need to upgrade media-ctl and yavta to versions that support interlaced formats. media-ctl has been moved to v4l-utils (http://git.linuxtv.org/cgit.cgi/v4l-utils.git/) and yavta is hosted at git://git.ideasonboard.org/yavta.git. You want to use the master branch for both trees. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
