Re: [gdal-dev] Problems generating a COG file

Hum, it would be useful if you could subset the input file to the minimum needed to reproduce the error and (possibly privately) share it to me. Even Le 20/08/2025 à 23:36, Javier Jimenez Shaw a écrit : Right. it fails $ gdal_translate web_mercator.tif web_mercator_jpeg.tif -co COMPRESS=JPE

Re: [gdal-dev] Problems generating a COG file

Can I do other useful tests tonight? Maybe just check/confirm that the issue is multithreading on the decoding side (which it looks to be) with: gdal_translate web_mercator.tif web_mercator_jpeg.tif -co COMPRESS=JPEG -co BIGTIFF=YES -of GTIFF -co TILED=YES -co BLOCKXSIZE=512 -co BLOCKYSI

Re: [gdal-dev] Issue opening RAR archive with non-latin filenames

Hi, Perhaps the key is in the message "to current locale." When I have seen something similar on Windows and when using my default code page 850, changing the code page into 65001 (UTF-8) has often helped. But I have never met UTF-16BE data. -Jukka Rahkonen- _

Re: [gdal-dev] Issue opening RAR archive with non-latin filenames

Denis, | VSIARCH: Pathname cannot be converted from UTF-16BE to current locale. This error message comes directly from "libarchive" that GDAL uses underneath for RAR support. You could check with that project. Maybe support for that encoding is missing, or there is some compilation option to

Re: [gdal-dev] Problems generating a COG file

Javier, - which GDAL version it is ? - the "corrupted double-linked list" is definitely a proof of either a bug, or a mis-configuration. This is a message we see sometimes when GDAL accidentally links against 2 different libproj. Can you check "ldd /path/to/libgdal.so" to see if there is not

[gdal-dev] Problems generating a COG file

Hi I am warping a file to EPSG:3857 and later generating a COG with JPEG compression. The input tif file has also JPEG compression. (I learned that I need the - dstalpha to keep it transparent) I am doing it in Ubuntu 22.04 using conda. First I tried this, using LZW as output of the warp GDAL_CA
