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 (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/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

we have stop/resume feature in our hls.js player for Live Playback.
When the user stops the playback, we call stopLoad() and detachMedia(). On resume, we call startLoad() followed by attachMedia().
The issue I’m encountering is that after resuming, hls.js sends a level playlist request, but it gets canceled, and the player starts requesting old .ts segments instead.
I've attached a screenshot with color-coded blocks:
- Green block: Requests made before stopping playback. The last segment fetched was 3.ts.
- Dark red block: Playlist request sent after resuming, which gets canceled.
- Blue block: Requests for old .ts segments following the canceled playlist request.

we have clean up process in our multicast playback which removes old ts segments. That's why you will see 404s for the old after user resumes the playback.
we do have higher frag retry count and once retry exhausts, we try to recover one more time by calling stopLoad and startLoad. At this time, Hls.js gets the refreshed playlist and start fetching new segments but It never plays the Video.
In our other playback modality like Play from a cache serve, we don't cleanup old ts segments that often. So, Hls.js requests one or two old ts segments and it gets 200 response but by that time it gets a refreshed Level playlist and all plays fine.

Expected behaviour

If TS segments have already been loaded and the stopLoad() method is called, then upon calling startLoad() again, hls.js should not request the previously fetched TS segments, as they were already successfully retrieved.

What actually happened?

After calling stopLoad() followed by startLoad(), Hls.js requests old TS segments. When these requests result in 404 errors, it cancels the level playlist call. Once the TS segment retries are exhausted, we attempt to recover playback by calling stopLoad() and startLoad() again. While the player receives the refreshed playlist and begins fetching new segments, it gets stuck and fails to play the stream.

enableLazyURLResolve is not a known config option.

What's the behavior like with changes in #6853? Branch build: https://bugfix-frag-retry-no-alterna.hls-js-4zn.pages.dev/demo/

Resolves #6854

robwalch · 2024-11-20T01:27:43Z

With #6855 hls.js will wait for expired playlists to be refreshed before requesting segments. This should resolve the issue. Please let me know how it works for you: https://bugfix-live-resume-wait-for.hls-js-4zn.pages.dev/demo/

LalitAgrawala004 · 2024-11-20T01:38:48Z

Sure @robwalch .. I did verify #6853 once this evening.. it was definitely much better and was able to play the video but it did request old ts segments. I wanted to do more testing tomorrow but I will test the new build and let you know.

LalitAgrawala004 · 2024-11-20T18:38:20Z

@robwalch I tried #6855 and I am seeing the same behavior as #6853 .. it is still going after old ts segments afrer resume.

But once you restart, besides the fragment 404s (which should be available for for 90 seconds (its length is 60 plus 3x target duration) from the last time is was retrieved, the playlist itself 404s and then when it does update, it contains only one segment, then two with a combined duration of 80 seconds (instead of the expected ~20):

[log] > startLoad(-1)

// fragments 404 - has it been more than 90 seconds?

I just pushed some additional changes that will enhance the logs that will help tell why your segments may not be considered stale after these changes: 30c05b3. If you could, please give it another run and share your logs again. Thank you.

The segments are 404ing too early. Segments removed from a live HLS playlist should remain available for the duration of the playlist plus the duration of the segment. With #6855 HLS.js will only ignore segments in the playlist if it was loaded more than the total duration plus three target durations (so ~60 seconds in this case). The last response was only 34.7 seconds ago ("age") so the segments should still be available:

Made one more update to reduce the expected availability to playlist duration + target duration (from duration + 3 target durations): e9fd578

@robwalch understood .. I took the latest build this morning and tested it .. it is working the way you mentioned. I need to talk to my backend team to fix the clean up of playlist. Thanks for looking into it. May I know when the fix will be available?

robwalch · 2024-11-21T16:52:38Z

The fix will be available in pre-release with v1.6.0-beta.2 coming within the next week. v1.6.0 will be in beta until the start of 2025.

robwalch · 2024-11-21T16:55:05Z

You can workaround this issue in v1.5 by removing Level.details on stopLoad or detach, and/or by calling hls.pauseBuffering() before startLoad() followed by hls.resumeBuffering() following LEVEL_UPDATED.
