mpd-parser 0.0.4

lxml based parser for DASH manifests (mpd files)

mpd-parser

Installation

$ python -m pip install mpd-parser

Usage

Importing

from mpd_parser.parser import Parser

parse from string

with open("path/to/file.mpd", mode="r") as manifest_file:
    mpd_string = manifest_file.read()
    parsed_mpd = Parser.from_string(mpd_string)

Overview

A utility to parse mpeg dash mpd files quickly This package is heavily inspired by mpegdash package the main difference is that I choose to relay on lxml for parsing, and not the standard xml library.

The decision to implement it with lxml is for two reasons:

1. lxml is faster then minidom
2. lxml mimics the ElementTree API which is a more pythonic approach to XMLs

mpegdash package has two distinct advantages over this package:

1. it does not require third party libraries.
2. it uses the classic DOM approach to parsing XML files. it is a well known standard.

Currently, the package supports parsing only, not the creation or object->string conversion.

Benchmarks

TBA

Example manifests

Taken from https://ottverse.com/free-mpeg-dash-mpd-manifest-example-test-urls/ These are what I used to test and benchmark the package.

Missing unit-tests

1. tags
2. attribute parsers
3. full manifest testing
