From 73f18ace91fb040f7016df28e66ebe5ce7177e66 Mon Sep 17 00:00:00 2001 From: wm4 Date: Wed, 17 Oct 2012 13:46:46 +0200 Subject: [PATCH] mp_image: hack to fix alignment for certain image formats This is to get rid of swscale alignment warnings with the new OSD code. Only image formats used by it are fixed. Solving this generally would require some more effort. (Possibly by using libav's allocation functions plus lots of testing.) --- libmpcodecs/mp_image.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/libmpcodecs/mp_image.c b/libmpcodecs/mp_image.c index 28472d092c..1ba9e8e753 100644 --- a/libmpcodecs/mp_image.c +++ b/libmpcodecs/mp_image.c @@ -26,11 +26,30 @@ #include "libmpcodecs/img_format.h" #include "libmpcodecs/mp_image.h" +#include "libmpcodecs/sws_utils.h" #include "libvo/fastmemcpy.h" #include "libavutil/mem.h" +#include "libavutil/common.h" void mp_image_alloc_planes(mp_image_t *mpi) { + if (mpi->imgfmt == IMGFMT_BGRA) { + mpi->stride[0]=FFALIGN(mpi->width*4,SWS_MIN_BYTE_ALIGN); + mpi->planes[0]=av_malloc(mpi->stride[0]*mpi->height); + mpi->flags|=MP_IMGFLAG_ALLOCATED; + return; + } + if (mpi->imgfmt == IMGFMT_444P16 || mpi->imgfmt == IMGFMT_444P) { + int bp = mpi->imgfmt == IMGFMT_444P16 ? 2 : 1; + mpi->stride[0]=FFALIGN(mpi->width*bp,SWS_MIN_BYTE_ALIGN); + mpi->stride[1]=mpi->stride[2]=mpi->stride[0]; + int imgsize = mpi->stride[0] * mpi->height; + mpi->planes[0]=av_malloc(imgsize*3); + mpi->planes[1]=mpi->planes[0]+imgsize; + mpi->planes[2]=mpi->planes[1]+imgsize; + mpi->flags|=MP_IMGFLAG_ALLOCATED; + return; + } // IF09 - allocate space for 4. plane delta info - unused if (mpi->imgfmt == IMGFMT_IF09) { mpi->planes[0]=av_malloc(mpi->bpp*mpi->width*(mpi->height+2)/8+
