I have some code that generates 24bit RGB or 8bit greyscale reduced resolution and stretched (using a VRT) JPEGS from our satellite imagery. I’m having an issue where CreateCopy (and gdal_translate) is hanging. The data I’ve had trouble with is a single band (Pan) GeoEye-1 image: http://geoeyemediaportal.s3.amazonaws.com/assets/images/ChannelPartnerPortal/Australia/Geo_11bit/Example1.zip (500+mb, sorry). If that link doesn't work, try: http://www.geoeye.com/CorpSite/resource/sample_imagery_response.aspx The VRT (test.vrt, also attached) is: {{{ 0.0 /vsizip/Example1.zip/po_311944_pan_0000000.tif 1 -53.125 1.51785714286 }}} The following gdal_translate command succeeds, i.e the output jpg is created and the progress meter says it’s done, but just never returns. {{{ $ gdal_translate -of jpeg test.vrt test.jpg Input file size is 800, 1870 0...10...20...30...40...50...60...70...80...90...100 - done. }}} If a tif is output then the command completes and returns as expected: {{{ $ gdal_translate test.vrt test.tif 0...10...20...30...40...50...60...70...80...90...100 - done. $ }}} I've attached the VRT, a python script that demonstrates the same issue with CreateCopy() and a a gdb trace run on gdal_translate (but I don't have a version of gdal with debug symbols so don't know if it's of any use).",defect,closed,normal,1.10.0,GDAL_Raster,unspecified,normal,fixed,,
