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
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
