From 8dbe5856410ee10ac4a9368105149efdacfac994 Mon Sep 17 00:00:00 2001 From: Oskar Arvidsson Date: Tue, 29 Mar 2011 17:48:59 +0200 Subject: Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is _[_] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support.
