Hi I am working in a branch to read the raw thermal data from DJI jpg images. It is similar to FLIR, ... but different. The branch is for now in an early stage of development. My problem is that an existing tests are failing.
In this function I am checking the image is tagged as DJI in the EXIF: https://github.com/jjimenezshaw/gdal/blob/dji-thermal/frmts/jpeg/jpgdataset.cpp#L405 auto make = GetMetadataItem("EXIF_Make"); bool bMakerDJI = make && STRCASECMP(make, "DJI") == 0; if (!bMakerDJI) return; The problem is that the "GetMetadataItem" call is somehow writing another entry in the GetMetadataDomainList, an empty string. An then this test is failing: https://github.com/jjimenezshaw/gdal/actions/runs/16811268016/job/47616930397#step:6:4277 47: E [ 47: E 'IMAGE_STRUCTURE', 47: E + '', 47: E 'FLIR', 47: E 'SUBDATASETS', 47: E 'DERIVED_SUBDATASETS', 47: E ] Is there a better way to get the EXIF "Make" tag, without polluting the domain list? Or is there a hidden bug somewhere? Thanks.
