mpd-inspector 0.2.0

A module to parse, analyze and validate MPEG-DASH MPD

mpd-inspector

Overview

This is a module to parse MPEG-DASH Media Presentation Documents (aka. MPD) from files or URLs, and interpret them This package is built as a fork from the excellent mpd-parser. The main reasons for forking it are:

1. I needed to change the behaviour to be closer to the MPEG-DASH spec, in particular DASH-IF IOP rules.
2. I wanted to parse all MPD attributes into native Python types (including for datetimes and durations)
3. I wanted to be able to expose unparsed elements
4. I wanted to add a layer of inspection/analysis to make it possible to calculate implicit/derived values (eg. start and duration of periods in multi-period MPD) - in particular again for validation against the DASH-IF Interoperability guidance

Installation

$ python -m pip install mpd-inspector

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)

parse from file

input_file = "path/to/file.mpd"
mpd = Parser.from_file(input_file)

parse from url

input_url = "https://my-server.com/path/to/stream.mpd"
mpd = Parser.from_url(input_url)

inspect it

mpd_inspector = MPDInspector(mpd)

convert back to string

mpd_as_xml_string = Parser.to_string(parsed_mpd)
