Enormous playback delay on low bandwidth connection(5Mb/s throttling) when start position is specified #3950

Andrewtop · 2021-05-26T14:51:53Z

What version of Hls.js are you using?

v.1.0.4

What browser and OS (including versions) are you using?

Mac OS 10.15.6
Chrome Version 90.0.4430.212 (Official Build) (x86_64)

Test stream:

Can't provide the stream from our app but I've found https://edge.flowplayer.org/elephant/playlist.m3u8 which can be used to reproduce .

Configuration:

Set high "startPosition".

{
 "debug": true,
  "enableWorker": true,
  "lowLatencyMode": true,
  "backBufferLength": 90,
  "startPosition": 531
}

Checklist

The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
The issue occurs in the stable client on https://hls-js.netlify.com/demo and not just on my page

The issue occurs in the latest client on https://hls-js-dev.netlify.com/demo and not just on my page

The stream has correct Access-Control-Allow-Origin headers (CORS)
There are no network errors such as 404s in the browser console when trying to play the stream

Steps to reproduce

Before playing the video :

Turn on network throttling to 5 Mb/s in dev tools;
Disable cache in dev tools;
Play the video

Expected behavior

It takes reasonable amount of time to play the VOD from start position at least the same as in v0.14.16. (it takes around 7 sec before playback starts).

No request to load audio chunks from the very beginning of the stream.

Actual behavior

VOD doesn't start to play in 20 sec which is almost 3 times more than in v0.14.16.

Hls starts to load audio chunks starting from the startPosition then loads audio chunks from the very beginning of the stream then loads chunks starting from the startPosition again:
