From 71617884a2a673908bd5c0f73d4f91fdca3da82a Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Tue, 10 Dec 2013 20:16:08 +0100 Subject: aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included. --- libavcodec/aarch64/rv40dsp_init_aarch64.c | 48 +++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 libavcodec/aarch64/rv40dsp_init_aarch64.c (limited to 'libavcodec/aarch64/rv40dsp_init_aarch64.c') diff --git a/libavcodec/aarch64/rv40dsp_init_aarch64.c b/libavcodec/aarch64/rv40dsp_init_aarch64.c new file mode 100644 index 0000000000..0bb404f6d2 --- /dev/null +++ b/libavcodec/aarch64/rv40dsp_init_aarch64.c @@ -0,0 +1,48 @@ +/* + * This file is part of Libav. + * + * Libav is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * Libav is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
