Problems with --insert and --extract in exiv2 app #1934
Description
Describe the bug
There are 4 problems:
- When extracting to a raw metadata file (.exv), if the file already exists, the data is not erased before writing. Instead the file is only updated with the extracted data. No warning is given, even when using
--verbose. - When extracting a thumbnail, this cannot be sent to stdout.
- When extracting to stdout, if
--verboseis used, the output is corrupted by additional information. - When attempting to insert from a raw metadata file (.exv), instead, the program attempts to insert an XMP sidecar file (.xmp). If the .xmp file exists, then the data is inserted and no warning is given, even with
--verbose.
To Reproduce
- Extracting to a raw metadata file (.exv)
