pymkv2

PyPI Version License codecov versions

pymkv2 is a Python wrapper for mkvmerge and other tools in the MKVToolNix suite. It provides support for muxing, splitting, linking, chapters, tags, and attachments through the use of mkvmerge.

About pymkv2

it's a fork of the pymkv project. pymkv2 is a Python 3 library for manipulating MKV files with mkvmerge. Constructing mkvmerge commands manually can quickly become confusing and complex. To remedy this, I decided to write this library to make mkvmerge more scriptable and easier to use. Please open new issues for any bugs you find, support is greatly appreciated!

Installation

mkvmerge must be installed on your computer, it is needed to process files when creating MKV objects. It is also recommended to add it to your $PATH variable but a different path can be manually specified. mkvmerge can be found and downloaded from here or from most package managers.

To install pymkv from PyPI, use the following command:

$ pip install pymkv2

You can also clone the repo and run the following command in the project root to install the source code as editable:

$ pip install -e .

Language code utilities

pymkv exposes a normalized API for comparing and translating language codes across ISO 639-1, /B, /T, 639-3, BCP 47, and English language names. Use these helpers instead of comparing language strings directly — language_ietf="zh-Hans" and language="chi" should match, and they do via languages_match.

from pymkv import (
    MKVFile,
    get_iso639_2,
    languages_match,
    language_equivalents,
    normalize_language,
)

get_iso639_2("English")        # "eng"
get_iso639_2("fra")            # "fre"  (canonical /B)
normalize_language("zh-Hans")  # "chi"  (BCP 47 subtag stripped)
languages_match("zho", "zh")   # True
language_equivalents("eng")    # frozenset({"eng", "en"})

# MKVTrack setter is now lenient — any recognized form is accepted and
# canonicalized to /B on store.
mkv = MKVFile("path/to/file.mkv")
track = mkv.tracks[1]
track.language = "Chinese"        # stored as "chi"
track.matches_language("zh")       # True (works against language_ietf too)
track.effective_language           # "chi" — normalized /B
