Looking at
https://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/openjpeg/openjpegdataset.cpp?rev=40418
I now see the GDAL made changes to enable multi-threading.
Thanks

Hi,
In http://gdal.org/frmt_jp2openjpeg.html under 'Thread Support' section there
is the following:
"Starting with GDAL 2.3, this multi-threading at code-block level is
automatically enabled by GDAL".
Was meant "Starting with OpenJpeg 2.3, ..." ?
If yes, was that enabling made in the 'OpenJ

this be cause by 'gdal_translate' not using threads
that the new openjpeg uses for performance boost ?
Or could it one of GDAL configuration or the built version of OpenJpeg need to
be rebuilt using different config ?

Thanks Even for your response. That clarifies more the current capabilities of
GDAL on parallel processing.I think that as parallel processing gain more
momentum, GDAL and multiple GDAL based applications would benefit for adopting
it.In Windows world, parallel processing was added in Visual Stu
Simultaneous writers to different dataset or the same dataset ?In related
topic, can GDAL writte to different dataset in a parallel way ?ex. convert
multiple datasets to different output datasets in a parallel way.Would those
parallel operations not be affected by GDAL caching for bot read and
Great ! Thank you Frank for the prompt response.Noury FarahOn 12-02-25 02:28

Hi,
I have a question about UTF-8 support per this rfc:
http://trac.osgeo.org/gdal/wiki/rfc30_utf8_filenames
If UTF-8 is turned on, will the following calls assume that the passed strings
are UTF-8 ?and the passed folder paths should be in UTF-8 ?

Hi,
Using gdalinfo (http://vbkto.dyndns.org:1280/sdk/) on few geopdf files did not
recognized the files as supported.Other files were opened and recognized ok.
Here are 3 files that were unrecognized:

Hi,
Using gdalinfo from GDAL 1.8 release build (http://vbkto.dyndns.org:1280/sdk/)

To debug it I built gdal from source and registered only open jpeg 2000 driver:
