MP4PSSH

A TypeScript parser to convert a Base64-encoded string representing an MP4 PSSH box into a POJO. More information about MP4 PSSH boxes can be found here.

Installation

This repository is hosted on NPM. Install this package using:

npm i @re/mp4pssh

The parser can then be imported using:

import { PSSHParser } from '@re/mp4pssh'

Usage

Begin by getting a Base64-encoded string representing an MP4 PSSH box.

Instantiation

Create a new instance of the PSSHParser class:

const psshParser = new PSSHParser();

Parsing the PSSH

Use the parsePSSH() method to parse the Base64-encoded PSSH box into a POJO:

const pssh = psshParser.parsePSSH(<BASE64_PSSH>);

Users can then access the information encoded in the PSSH:

• version <number>: The version of the parsed PSSH

• systemId <string>: The ID of the system that will consume the PSSH data

• kidCount <number>: The number of KIDs included in the PSSH

• kids <string[]>: The KIDs included in the PSSH

• dataSize <number>: The length of ths PSSH data (in bytes)

• data <Uint8Array>: The PSSH data
