From b2787845fb91da18ebb079dc9297f92d990e9fe1 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 27 Apr 2007 12:31:02 -0300 Subject: V4L/DVB (5289): Add support for video output overlays. Add V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY support. Also add support for local and global alpha overlays. Add new field enums V4L2_FIELD_INTERLACED_TB and V4L2_FIELD_INTERLACED_BT. These changes are needed to support the ivtv On Screen Display features.
