Specify the behavior of an HLS-based video so it has the configured playback responses. It is useful for testing player playback behavior and measurement SDKs.
git cloneyarn installnode app.js- Browse to http://localhost:3000/index.html
You specify how a video plays by providing a playback specification in the path to the video manifest file. A playback manifest will be created and each action will be taken for the specified segment.
A specification looks something like this: 's5-p30-e404'
Each action is separated by a '-', the entire url looks like this: http://localhost:3000/s5-p30-e404/media.m3u8
The following options are available:
- Startup Time delay: 's' + delay time (optional, defaults to 5 seconds)
- Playback: 'p' + playback time (optional, defaults to 30 seconds)
- Rebuffer: 'r' + delay time (optional, defaults to 30 seconds)
- Note: "rebuffer of X seconds" does not translate to exactly X seconds of rebuffering, it delays delivery of the segment for X seconds
- Error: 'e' + error code (optional, defaults to code 500)
Some examples of playback specifications: Long startup (5 second startup delay and then regular playback): http://localhost/s5-p30/media.m3u8
Stalling during the video (10 seconds of playback, 9 seconds of delay, 10 more seconds of playback): http://localhost/p10-r9-p10/media.m3u8
500 Server Error to end the stream: http://localhost/p30-e/media.m3u8
Use the url, including the desired specification, with your favorite video player.
