This package contains useful scripts to manipulate HLS manifests at origin or edge server.
|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|
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.
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
These scripts are executed by the request handler at the origin webserver. The scripts output the generated manifest file to stdout
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
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"
--help show help message and exit --mediaplaylist PL name of media playlist --startover TS YYYY-mm-dd HH:MM:SS
