Author: Boyuan Zhang <boyuan.zh...@amd.com> Date: Thu Jul 21 19:40:15 2016 -0400 vl/util: add copy func for yv12image to nv12surface v2 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 <boyuan.zh...@amd.com> Signed-off-by: Christian König <christian.koe...@amd.com> --- 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 9196afc..7e743de 100644 --- a/src/gallium/auxiliary/util/u_video.h +++ b/src/gallium/auxiliary/util/u_video.h @@ -130,6 +130,43 @@ 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, int src_plane, int src_field, _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-commit
