Command line tools for HLS manipulation at origin or edge server

Project description

Description

This package contains useful scripts to manipulate HLS manifests at origin or edge server.

Script Description
hls-capture Create a VOD playlist between two timestamps in a LIVE playlist
hls-live-from-vod Create a LIVE playlist from a set of VOD playlists
hls-startover Create a LIVE playlist from a specific starttime in another LIVE playlist

Preconditions

These scripts are based on the assumption that all HLS manifest files and segments are archived at the origin server where these scripts are executed. The archive for a specific live stream contains the history for all HLS manifest updates. For example:

Live HLS stream called ‘foo’ is archived in the directory /archive/foo on the server. It contains all updated HLS manifest files with a unix timestamp when it was last updated.

master800.m3u8-1472977456
master800.m3u8-1472977465
master800.m3u8-1472977475

All video segments are also stored in the same directory.

Installation

From source

git clone https://github.com/Eyevinn/hls-origin-scripts.git
cd hls-origin-scripts
python setup.py install

From Python Package Index

pip install hlsorigin

Usage

These scripts are executed by the request handler at the origin webserver. The scripts output the generated manifest file to stdout

hls-capture

Generate a VOD playlist from a LIVE HLS where segments and manifest files are archived at /hlsarchive/stream/. A 20 minutes VOD manifest from 11:45 to 12:05 is created in this case.

hls-capture /hlsarchive/stream/ --mediaplaylist master800.m3u8 --in "2016-09-04 11:45:00" --out "2016-09-04 12:05:00"

By default any cueout periods (e.g. ads) are removed and a discontinuity tag is added in the generated manifest. Available options:

--help                  show help message and exit
--in TS             YYYY-mm-dd HH:MM:SS
--out TS                YYYY-mm-dd HH:MM:SS
--mediaplaylist PL  name of media playlist
--noremovecueout        do not remove segments in cue out periods

hls-startover

Generate a new LIVE HLS playlist with a new start position. This is useful when needing a startover functionality but the user should not be able to watch before the startover position.

hls-startover /hlsarchive/stream/ --mediaplaylist master800.m3u8 --startover "2016-09-04 16:25:00"

Available options:

--help                  show help message and exit
--mediaplaylist PL  name of media playlist
--startover TS      YYYY-mm-dd HH:MM:SS
