GDAL Mailing List,
I am wondering if anyone has had success JPIP streaming with GDAL &
Kakadu 7.
We are looking to upgrade to Kakadu 7 (from 6.3.1) for the new UDP
capability.
I have managed to get everything compiled, with the JPIP support
included, however when I stream imagery I get invalid data the current
region I am requesting. The data I get sent from the server seems to
be from an invalid region on the image, resulting in major artefacts.
I believe this is due to changes in kdu_window, as mentioned in
jp2kakdataset.cpp, but I have extremely limited experience in
modifying the GDAL Source.
The code changes I made are as explained here:
http://trac.osgeo.org/gdal/ticket/4575
I have also uncommented line 59 (#define USE_JPIP).
Michael,
I'm the reporter of ticket #4575. I (we) have not tried GDAL with Kakadu
with JPIP - in fact JPIP is unknown to me but it looks interesting and
probably would be very useful to us too.
Best regards,
Ari
Any help would be much appreciated.
