From: Clément Bœsch <clem...@stupeflix.com> --- This code is mirroring the ARM version.
It's not tested on real hardware (qemu only), so I have no idea about performance. This also means I didn't put any prefetch mechanism (which had a noticeable impact on performance on ARM). Last but not least, the 32-bit precision functions are added (and tested) but are not enabled at all, just like the ARM counterpart. --- libswscale/aarch64/Makefile | 3 + libswscale/aarch64/swscale_unscaled.c | 142 +++++++++++++++ libswscale/aarch64/yuv2rgb_neon.S | 332 ++++++++++++++++++++++++++++++++++ libswscale/swscale_internal.h | 1 + libswscale/swscale_unscaled.c | 2 + 5 files changed, 480 insertions(+) create mode 100644 libswscale/aarch64/Makefile create mode 100644 libswscale/aarch64/swscale_unscaled.c create mode 100644 libswscale/aarch64/yuv2rgb_neon.S diff --git a/libswscale/aarch64/Makefile b/libswscale/aarch64/Makefile new file mode 100644 index 0000000..823806e --- /dev/null +++ b/libswscale/aarch64/Makefile @@ -0,0 +1,3 @@ +OBJS += aarch64/swscale_unscaled.o + +NEON-OBJS += aarch64/yuv2rgb_neon.o diff --git a/libswscale/aarch64/swscale_unscaled.c b/libswscale/aarch64/swscale_unscaled.c new file mode 100644 index 0000000..8b04c2b --- /dev/null +++ b/libswscale/aarch64/swscale_unscaled.c @@ -0,0 +1,142 @@ +/* + * This file is part of FFmpeg. + * + * FFmpeg 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. + * + * FFmpeg 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.
