hlsorigin 0.0.13

Command line tools for HLS manipulation at origin or edge server

# 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
