These Python scripts are demonstrators of mediameta Python package functionality.

See https://github.com/dandelion-systems/mediameta for the source code of the package and installation tips.
sample_mm_cli.py is the minimalistic sample. It scans the local folder '.img' for JPEG, HEIC or TIFF impages and prints out their metadata into standard output. The other two Python scripts are a bit more sophisticated, see below.
mmeta parses all metadata it finds in a JPEG, HEIC, TIFF or MOV file and either creates a file with the same name and .metadata extension or displays its findings in a standard output. It operates on folders or on individual files. Should it find GPS coordinates in an image file, a link to Google Maps will be generated too.
Kindly mind that there are certain metadata tags that are considered non-printable. They parsed from files anyway and you can still access them in your own code, but mmeta will not show them.
See the command line options for details.
Usage samples:
Print all metadata for all files in a folder into standard output:
mmeta --display --folder ~/img
Create a .metadata file for a specific image:
mmeta ~/img/IMG005.HEIC
Display metadata for a specific image using an alternative encoding:
mmeta --display --encoding=cp1251 ~/img/img1.jpeg
mrename uses the date and time when an image or video was taken to rename the file. It operates on a folder which can contain a mixture of JPEG, HEIC, TIFF and MOV files. In case of images it looks either at DateTimeOriginal EXIF tag or DateTime TIFF tag. Should it encounter a MOV file, it tries to use com.apple.quicktime.creationdate metadata field.
Control the prefix, postfix and time stamp format through the command line options. Dry runs are possible too.
Should two or more files happen to have the same name after renaming, an index will be appended at the end of the name.
Usage samples:
Rename all image and video files in a folder, use YYYY-MM-DD HH-mm-ss as a new file name template:
mrename ~/img
Do the same but with custom prefix:
mrename --prefix="Souvenir de" ~/img
And again the same but keeping only the date, not the time in a file name:
mrename --prefix="Souvenir de" --time-stamp=%Y-%m-%d ~/img
