From 7a851153d3fe1a9e0d60bf11053870d1ea8241e6 Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Sat, 4 Aug 2012 00:50:21 +0100 Subject: mpegvideo: convert mpegvideo_common.h to a .c file This file defines a single, huge function, MPV_motion(), which although being declared inline is not actually inlined by the compiler (for good reason). There is thus no sense in defining this function in a header file, resulting in multiple copies of it in the final library.
