Playlist which plays well in Firefox fails in Chrome by requesting same segment repeatedly

Open cboRD181 opened this issue 5 months ago • 2 comments

What version of Hls.js are you using?

v1.6.12

What browser (including version) are you using?

Chrome Version 140.0.7339.186 (Official Build) (arm64)

What OS (including version) are you using?

MacOS Sonoma

Test stream

https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Ftestplaylist.pages.dev%2Fplaylist_8-29.m3u8&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==

Configuration

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

Additional player setup steps

If playing from the first generated segment from the source file, Chrome begins playback:

https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Ftestplaylist.pages.dev%2Fplaylist.m3u8&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==

but stalls and requests segment 13 in a loop.

If playing from a playlist which starts beyond the first segment, as in the first test stream link, Chrome fails immediately.

Both play smoothly in Firefox.

Checklist

  • [x] The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
  • [x] The issue occurs in the stable client (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
  • [x] The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/demo and not just on my page
  • [x] The stream has correct Access-Control-Allow-Origin headers (CORS)
  • [x] There are no network errors such as 404s in the browser console when trying to play the stream

Steps to reproduce

  1. Load the test streams in Chrome 140

Expected behaviour

Player should smoothly append new segments

What actually happened?

Player stalls either immediately (in the case of the first test stream) or after several segments (in the case of second test stream)

We have been hitting this issue as well:

What version of Hls.js are you using? v1.6.14

What browser (including version) are you using? ChromeOS version: Version 137.0.7151.137 (Official Build) (64-bit)

What OS (including version) are you using? ChromeOS version: Version 137.0.7151.137 (Official Build) (64-bit)

We hit same issues on ChromeOS v132. Interestingly, when testing on ChromeOS v141 there were no issues. Also, when rolling back to older HLS version there are no issues (0.14.17). So some conflict with newer HLS ABR logic and MediaSource API in these older versions of ChromeOS.

I explored bypassing issue by setting startLevel=0 and disabling autoLevel for these specific versions but same issue occurs.

We would like to use latest HLS but this is a blocking issue for us so please fix! Thanks.
