This class is written as a context manager to ensure the process is exited if you are done. Return json.loads(self.execute('-G', '-j', '-n', *filenames)) Stdin=subprocess.PIPE, stdout=subprocess.PIPE)ĭef _exit_(self, exc_type, exc_value, traceback):

I also included get_metadata() to read the metadata in JSON format: import subprocessĭef _init_(self, executable='/usr/bin/exiftool'): Here's a simple class that launches an exiftool process and features an execute() method to send commands to that process. ExifTool supports JSON output, which is probably the best option for reading the metadata. You can then send commands to the process via stdin, and read the output on stdout. To avoid launching a new process for each image, you should start exiftool using the -stay_open flag.
