From 23b4ab1738f0f4470449c848b37b43568df4a60c Mon Sep 17 00:00:00 2001 From: Boyuan Zhang Date: Thu, 21 Jul 2016 19:40:15 -0400 Subject: [PATCH] vl/util: add copy func for yv12image to nv12surface v2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add function to copy from yv12 image to nv12 surface for VAAPI putimage call. We need this function in VaPutImage call where copying from yv12 image to nv12 surface for encoding. Existing function can't be used because it only work for copying from yv12 surface to nv12 image in Vaapi. v2: cleanup variable types and commit message Signed-off-by: Boyuan Zhang Signed-off-by: Christian König --- src/gallium/auxiliary/util/u_video.h | 37 ++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) diff --git a/src/gallium/auxiliary/util/u_video.h b/src/gallium/auxiliary/util/u_video.h index 9196afc11be..7e743de253e 100644 --- a/src/gallium/auxiliary/util/u_video.h +++ b/src/gallium/auxiliary/util/u_video.h @@ -129,6 +129,43 @@ u_copy_yv12_to_nv12(void *const *destination_data, } } +static inline void +u_copy_yv12_img_to_nv12_surf(ubyte *const *src, + ubyte *dst, + unsigned width, + unsigned height, + unsigned src_stride, + unsigned dst_stride, + int field) +{ + if (field == 0) { + ubyte *src_0 = src[field]; + for (int i = 0; i < height ; i++) { + memcpy(dst, src_0, width); + dst += dst_stride; + src_0 += src_stride; + } + } else if (field == 1) { + const ubyte *src_1 = src[field]; + const ubyte *src_2 = src[field+1]; + bool odd = false; + for (unsigned i = 0; i < height ; i++) { + for (unsigned j = 0; j < width*2 ; j++) { + if (odd == false) { + dst[j] = src_1[j/2]; + odd = true; + } else { + dst[j] = src_2[j/2]; + odd = false; + } + } + dst += dst_stride; + src_1 += src_stride; + src_2 += src_stride; + } + } +} + static inline void u_copy_swap422_packed(void *const *destination_data, uint32_t const *destination_pitches, -- 2.30.2
