From 8c53d39e7f0604127bfc96fa1182c8abe3847ac6 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Sat, 15 Dec 2012 09:46:02 -0800 Subject: lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch().
