Extract all GPS positions from an AVCHD video.
Extract information from embedded documents in EPS and PDF files, embedded MPF images in JPEG and MPO files, streaming metadata in AVCHD videos, and the resource fork of Mac OS files. Implies the -a option. Use -g3 or -G3 to identify the originating document for extracted information. Embedded documents containing sub-documents are indicated with dashes in the family 3 group name. (ie. Doc2-3 is the 3rd sub-document of the 2nd embedded document.)
Preserve the filesystem modification date/time of the original file (FileModifyDate) when writing. Note that some filesystems (ie. Mac and Windows) store a creation date which is not preserved by this option. For these systems, the -overwrite_original_in_place option may be used to preserve the creation date.
