HLS downloader

About

Downloads a live HLS stream.

Usage

CLI

hls-downloader [-V] [-h] [-q QUALITY] -o FILE stream_url

Example

hls-downloader -q best -c 5 -o video.mp4 "https://......./stream.m3u8"

Dependencies

You need to have FFMPEG installed, even with the "merge using FFMPEG" feature disabled, as FFMPEG is still used to transmux the merged TS file into an MP4 file.

API

const download = require("node-hls-downloader").download;

await download({
    quality: "best",
    concurrency: 5,
    outputFile: "video.mp4",
    streamUrl: "https://......./stream.m3u8",
});

TypeScript is also supported, with types already provided.

Options

Note: options marked with 🔒 are mandatory.

stream_url, streamUrl 🔒

The URL to the stream (either the master file or a playlist).

--live, live

Download the stream as a live feed, refreshing the playlist and downloading only new segments. Automatically stops when no new segments are found after a while.

• Default: false

--ffmpeg-merge, mergeUsingFfmpeg

Merge TS segments using FFMPEG instead of basic concatenation. Not recommended, but you can use it if stuttering issues occur when merging the TS segments.

Where the TS segments will be stored.

• Default: a temporary directory

--merged-segments-file, mergedSegmentsFile

Location of the merged TS segments file.

• Default: a temporary file

-c, --concurrency, concurrency

How many threads to use for downloading segments.

• Default: 1

-q, --quality, quality 🔒*

Stream quality: worst, best, or max bandwidth.

* only mandatory if passing a master playlist stream URL

-o, --output-file, outputFile 🔒

Target file to download the stream to. If it already exists, it will be overwritten.

-h, --header, httpHeaders

Headers to use when making HTTP requests. On the CLI, the header argument can be repeated. Format is "Name: value".
