According to the maintainer of mediainfo, he uses 7zip on Windows to generate the tarballs. The commands used are:
7z a -r -ttar -mx9 MediaInfo_Lib_Source.tar MediaInfoLib\* 7z a -r -tgzip -mx9 libmediainfo_-1.tar.gz MediaInfo_Lib_Source.tar It seems that the .tar is not at fault -- if I run the first command and use Debian or Ubuntu's gzip, on the .tar, pristine-tar works. If I use the second command with a tarball generated from Debian or Ubuntu's tar, pristine-tar fails. The following test script demonstrates the issue: -----------8<------------- #!/bin/sh mkdir foo touch foo/bar tar -cf foo.tar foo 7z a -r -tgzip -mx9 foo.tar.gz foo.tar cd foo pristine-tar gendelta ../foo.tar.gz ../foo.tar.gz.delta ----------->8------------- -- Kind regards, Loong Jin
