a cli program to download video at m3u8 url

Project description

m3u8downloader
============================

m3u8downloader is a tool to download video at a m3u8 link. `HTTP Live
Streaming (HLS)<https://developer.apple.com/streaming/>`_ is becoming
popular. m3u8 playlist is used by HLS to serve video fragments of different
quality to different clients. This tool supports HLS master playlist and media
playlist. If master playlist is given, it selects the highest resolution
automatically. HLS fragment encryption is supported.

ffmpeg is used to convert the downloaded fragments into final mp4 video file.

Installation
------------

To install m3u8downloader, simply:

.. code-block:: bash

$ sudo apt install -y ffmpeg
$ pip install --user m3u8downloader

Limitations
-------------

This tool only parses minimum m3u8 extensions for selecting media playlist
from master playlist, downloading key and fragments from media playlist. If a
m3u8 file doesn't download correctly, it's probably some new extension was
added to the HLS spec which this tool isn't aware of.
