If the subprocess isn’t running, this method will do nothing. Terminate the exiftool process of this instance. n as common arguments, which are automatically included This method will issue a UserWarning if the subprocess isĪlready running. Start an exiftool process in batch mode for this instance. The format of the return value is the same as for Include group names, as usual in the format.
The first argument is an iterable of tags. Return only specified tags for the given files. Return only specified tags for a single file.ĭocumentation of execute_json(). Non-existent tags, in the same order as filenames. The return value is a list of tag values or None for The second argument is an iterable of file names. The first argument is a single tag name, as usual in the get_tag_batch ( tag, filenames ) ¶Įxtract a single tag from the given files. None if this tag was not found in the file. The return value is the value of the specified tag, or The return value will have the format described in theĭocumentation of execute_json(). Return all meta-data for the given files. The returned dictionary has the format described in theĭocumentation of execute_json(). Respective Python version – as raw strings in Python 2.x andĪs Unicode strings in Python 3.x. Pass in filenames according to the convention of the Unicode strings (type unicode in Python 2.x, type str (type str in Python 2.x, type bytes in Python 3.x) or The parameters to this function must be either raw strings Including the ExifTool group name in the format. All keys are Unicode strings with the tag names, The return value isĪ list of dictionaries, mapping tag names to the corresponding execute_json ( *params ) ¶Įxecute the given batch of parameters and parse the JSON output.Īutomatically adds the parameter -j to request JSON outputįrom exiftool and parses the output. Rarely be needed by application developers. This is considered a low-level method, and should The parameters must also be raw bytes, in whateverĮncoding exiftool accepts. The exiftool output is read up to theĮnd-of-output sentinel and returned as a raw bytes object, execute necessary to actually run the batch is appendedĪutomatically see the documentation of start() for This method accepts any number of parameters and sends them to execute ( *params ) ¶Įxecute the given batch of parameters with exiftool. Non-existent files to any of the methods, since this will leadĪ Boolean value indicating whether this instance is currentlyĪssociated with a running subprocess. Options will be silently ignored by exiftool, so there’s not To use the ExifTool instance as a context manager: The parent process exits, so a leaked subprocess will stay aroundĪ convenient way to make sure that the subprocess is terminated is Subprocesses won’t be automatically terminated if Happen, so you should not rely on the implicit process Garbage collected, but there are circumstance when this won’t ever This method will also be implicitly called when the instance is Terminate() method when finished using the instance. ToĪvoid leaving the subprocess running, make sure to call Start(), which will actually launch the subprocess. Most methods of this class are only available after calling Only work if the executable is in your PATH. You can pass the file name of the exiftool executable as anĪrgument to the constructor. Run the exiftool command-line tool and communicate to it. get_metadata_batch ( files ) for d in metadata : print ( "".
