Metia

A tool (and a wrapper of FFmpeg) to manipulate metadata of audio files.

This library is developed under Python 3.8.

Installation

pip install -U metia

Dependency

FFmpeg

Usage

All of the functionalities requires a ffmpeg/ffprobe build that has the corresponding codec that the media is using. To set a custom build of ffmpeg/ffprobe, set the variables metia.probe.FFPROBE_COMMAND and/or metia.writter.FFMPEG_COMMAND.

metia.Probe

If all you want to do is to read the metadata, use this class. This provides a wrapper of ffprobe to extract commonly-used media metadata, such as bit-rate and codec.

Some methods of this class may be helpful to video files too.

metia.Media

WORK IN PROGRESS

This class, apart from reading the metadata, allows you to alter the metadata, including changing the tags of the media file and adding a cover art to it.

This class, unlike metia.probe.Probe, is highly targeted to music files (with or without cover art). Although it is possible to integrate some video-related features, the demands might differ so much that it's unworthy compared to using the original ffmpeg commands. Thus, I believe a better way to utilize this library with videos is to use metia.probe.Probe to extract the information you want and use os.system (or other equivalent) to invoke a ffmpeg command. Alternatively, you may look for other more powerful ffmpeg wrappers that has support for more ffmpeg features, but that is beyond the scope of this project.

Command Line Interface

This tool provides command-line interface for convenience.
