2017-08-07Fix crash on Windows due to b7594c0fcb9dd3aa6356d72c4a525d76168da689Even Rouault
b7594c0fcb9dd3aa6356d72c4a525d76168da689 may put opj_tcd_tilecomp_t->data allocated by opj_alloc_tile_component_data() as the image->comps[].data. As opj_alloc_tile_component_data() use opj_aligned_malloc() we must be sure to ue opj_alined_malloc()/_free() in all places where we alloc/free image->comps[].data. Note: this might have some compatibility impact in case user code does itself the allocation/free of image->comps[].data
2017-08-07Decrease memory consumption for whole image single tile decoding.Even Rouault
We can use the same buffer for the tile decoding and the final image, and save the intermediate buffer to transfer between those. Effect on the decoding of MAPA (9944 x 13498 x 3 components of size byte) Peak memory from 4.5 GB to 2.7 GB Now: n5: 2699708767 (heap allocation functions) malloc/new/new[], --alloc-fns, etc. n1: 1610689344 0x4E77E07: opj_aligned_malloc (opj_malloc.c:61) <-- final image n1: 1610689344 0x4E7195B: opj_alloc_tile_component_data (tcd.c:676) n1: 1610689344 0x4E722D2: opj_tcd_init_decode_tile (tcd.c:816) n1: 1610689344 0x4E4BCF1: opj_j2k_read_tile_header (j2k.c:8597) n1: 1610689344 0x4E4C742: opj_j2k_decode_tiles (j2k.c:10324) n1: 1610689344 0x4E4E20E: opj_j2k_decode (j2k.c:7826) n1: 1610689344 0x4E52E42: opj_jp2_decode (jp2.c:1564) n0: 1610689344 0x40369E: main (opj_decompress.c:1459) n1: 815554560 0x4E72231: opj_tcd_init_decode_tile (tcd.c:1217) <-- working memory for code blocks: 9944*13498/64/64*8192*3 n1: 815554560 0x4E4BCF1: opj_j2k_read_tile_header (j2k.c:8597) n1: 815554560 0x4E4C742: opj_j2k_decode_tiles (j2k.c:10324) n1: 815554560 0x4E4E20E: opj_j2k_decode (j2k.c:7826) n1: 815554560 0x4E52E42: opj_jp2_decode (jp2.c:1564) n0: 815554560 0x40369E: main (opj_decompress.c:1459) n1: 219758391 0x4E4C0BF: opj_j2k_read_tile_header (j2k.c:4661) <-- ingestion of code stream n1: 219758391 0x4E4C742: opj_j2k_decode_tiles (j2k.c:10324) n1: 219758391 0x4E4E20E: opj_j2k_decode (j2k.c:7826) n1: 219758391 0x4E52E42: opj_jp2_decode (jp2.c:1564) n0: 219758391 0x40369E: main (opj_decompress.c:1459) n1: 39822000 0x4E7224F: opj_tcd_init_decode_tile (tcd.c:1224) <-- OPJ_J2K_DEFAULT_NB_SEGS*sizeof(opj_tcd_seg_t) per codeblock n1: 39822000 0x4E4BCF1: opj_j2k_read_tile_header (j2k.c:8597) n1: 39822000 0x4E4C742: opj_j2k_decode_tiles (j2k.c:10324) n1: 39822000 0x4E4E20E: opj_j2k_decode (j2k.c:7826) n1: 39822000 0x4E52E42: opj_jp2_decode (jp2.c:1564) n0: 39822000 0x40369E: main (opj_decompress.c:1459) n0: 13884472 in 49 places, all below massif's threshold (1.00%) Before: n5: 4493329848 (heap allocation functions) malloc/new/new[], --alloc-fns, etc. n2: 1610709160 0x4E77C87: opj_aligned_malloc (opj_malloc.c:61) n1: 1610689344 0x4E717DB: opj_alloc_tile_component_data (tcd.c:676) n1: 1610689344 0x4E72152: opj_tcd_init_decode_tile (tcd.c:816) n1: 1610689344 0x4E4BCF1: opj_j2k_read_tile_header (j2k.c:8597) n1: 1610689344 0x4E4C64A: opj_j2k_decode_tiles (j2k.c:10318) n1: 1610689344 0x4E4E08E: opj_j2k_decode (j2k.c:7826) n1: 1610689344 0x4E52CC2: opj_jp2_decode (jp2.c:1564) n0: 1610689344 0x40369E: main (opj_decompress.c:1459) n0: 19816 in 2 places, all below massif's threshold (1.00%) n1: 1610689344 0x4E43F36: opj_j2k_update_image_data.isra.7 (j2k.c:8743) n1: 1610689344 0x4E4C5C1: opj_j2k_decode_tiles (j2k.c:10358) n1: 1610689344 0x4E4E08E: opj_j2k_decode (j2k.c:7826) n1: 1610689344 0x4E52CC2: opj_jp2_decode (jp2.c:1564) n0: 1610689344 0x40369E: main (opj_decompress.c:1459) n1: 815554560 0x4E720B1: opj_tcd_init_decode_tile (tcd.c:1217) n1: 815554560 0x4E4BCF1: opj_j2k_read_tile_header (j2k.c:8597) n1: 815554560 0x4E4C64A: opj_j2k_decode_tiles (j2k.c:10318) n1: 815554560 0x4E4E08E: opj_j2k_decode (j2k.c:7826) n1: 815554560 0x4E52CC2: opj_jp2_decode (jp2.c:1564) n0: 815554560 0x40369E: main (opj_decompress.c:1459) n1: 402672336 0x4E4C545: opj_j2k_decode_tiles (j2k.c:10336) n1: 402672336 0x4E4E08E: opj_j2k_decode (j2k.c:7826) n1: 402672336 0x4E52CC2: opj_jp2_decode (jp2.c:1564) n0: 402672336 0x40369E: main (opj_decompress.c:1459) n0: 53704448 in 58 places, all below massif's threshold (1.00%)
