From 19bf00384a6d5bbe5d7b8afbcc25772e3675d423 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Fri, 11 Sep 2009 00:40:18 -0300 Subject: V4L/DVB (12748): em28xx: implement g_std v4l call We need to implement the g_std call, or else the default norm always gets returned, which breaks VBI capturing if you had changed the standard to NTSC using s_std. I had temporarily changed the default norm to NTSC so that zvbi-ntsc-cc wouldn't choke, so now that we are returning the correct value, switch it back to PAL as the default.
