From 7f68127fa11f08c5468537eb28ca6b8b95d70f08 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 29 Jul 2013 08:40:58 -0300 Subject: [media] videodev2.h: defines to calculate blanking and frame sizes It is very common to have to calculate the total width and height of the blanking and the full frame, so add a few defines that deal with that.
