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

1. Go to https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Fstream.mux.com%2F00pwc00zuut01c4KeE939WuLERfgSWYxFXOIMSnTW1X5y8.m3u8&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==
2. Play video and seek into half the video
3. Seek back with keyboard left arrow a few times
4. Wait until video freezes

Expected behaviour

Video plays back normally without freezing.

What actually happened?

The video playback freezes while audio playback is fine and is audible.

I tested it on Safari and Firefox and from brief testing it didn't seem to be an issue on those browsers.

This is a major issue for us since users tend to skip around in a video to see different highlights, etc. Thanks for looking into this issue.

I tested it on Safari and Firefox and from brief testing it didn't seem to be an issue on those browsers.

Is this specific to Chrome MSE playback?

If you perform a micro-seek (currentTime += 0.0001) at the right time (after playback resumes but all video frames are dropped until the next key frame) does that correct the issue? (Seeks flush the pipeline and is also necessary when crossing small video gaps to prevent stalls one second after entering a new video buffered range.)

Sounds related to the LL-HLS issue we have with video "freezing" when appends are performed over the play-head.

• Chrome does not recognise old keyframes (LL-HLS issue) #3596

Yes, it looked like a Chrome only thing in the tests I did.

Thanks, we can give that a try!

After reproducing this in Chrome 130 on mac, simply issuing another seek won't do the trick. Only one buffered TimeRange is reported so there is no signal that the decoding and rendering pipeline will stall or stop rendering at any point.

You should report this issue to Chrome and as a workaround, flush the forward buffer when seeking back into an unbuffered range.

To make things easier we can look into making frontBufferFlushThreshold remove any forward buffered range past the threshold get removed on seeking.

@robwalch lol was digging through some old notes when I saw this and thought it sounded an awful lot like... #3596 (which I had saved). I'm fairly confident this is related as well.

Other relevant links:

1. Code Frame Processing https://www.w3.org/TR/media-source/#sourcebuffer-coded-frame-processing (particularly step 9 and the note. This effectively says Chrome is spec compliant with its behavior, so unlikely they'll change or treat it as a bug, though it would clearly be an improvement)
2. Commit to Chromium with some relevant changes: chromium/chromium@ba8d79c

In theory, hls.js could try to keep track of segment boundaries in the SourceBuffer's TimeRanges to better identify if/when this scenario would occur, though I suspect that would be non-trivial.

So this asset contains overlapping samples?

[cjpillsbury]

It shouldn't (though I haven't confirmed). What I suspect is happening is the back buffer flushing is lopping off an IDR frame but not the whole GOP and we end up in edge cases from that with the seeking + fetching/buffering.

[robwalch]

HLS.js’s back buffer flushing doesn't operate on media less than a target durations behind the playhead. It is completely diabled by default and only set to 90 seconds on the demo page.

[robwalch]

If frames are being removed that should be reflected in the buffered ranges. I don't see how this is not a bug in Chrome.

particularly step 9 and the note

We’re not using append window

[robwalch]

I should add that I reproduced the issue with default settings: No HLS.js back buffer removal whatsoever. If HLS.js was performing back buffer removal, I would expect it to re-buffer any fragments that overlap with the flushed range.
