Test stream

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

Load the provided demo page on a Foxtel STB*. The demo is using a VOD stream with alternate audio tracks, which is needed for reproduction.
Playback will start toward the end of the stream "startPosition": 600.
Seek back toward the start of stream in 60 second increments, i.e. video.currentTime = video.currentTime - 60.
After 5-8 seeks, observe playback stalls and does not recover.
Observe the QuotaExceededError error in logs.

*This issue has only been observed on Foxtel Australia iQ3/iQ4 set top boxes. I have not reproduced on other devices or browsers. Foxtel iQ3 user agent:
'Mozilla/5.0 (ARRIS_Foxtel_STB_DGX7000NF; Linux mipsel) AppleWebKit/605.1.15 (KHTML, like Gecko) WPE ARRIS_Foxtel_STB_DGX7000NF /1.21.3.9 (Foxtel,DGX7000NF)'

Expected behaviour

On the QuotaExceededError, the buffers should be flushed and playback should resume.

What actually happened?

Playback stalls and does not recover. Calling play or seeking does not revive playback.
Looking at the logs, the audio buffer is flushed but the video buffer is not. After the audio buffer flush, new fragments fail to load in the audio buffer.

Related to Flush Front Buffer #5479

robwalch · 2023-06-22T18:58:07Z

Thanks for the issue.

Unfortunately there is no way to have HLS.js automatically manage disconnected forward buffered ranges. I’d like there to be, but haven’t come up with a plan to either add new config options, or modify some or all of the existing ones.

backBufferLength manages the buffer behind the playhead only. Semantically forwardBufferLength might work.

I’ve also heard the feedback that the maxBuffer setting are not intuitive as they control stream controller idling, vs expected overall buffer/memory usage. Either modifying them, or replacing/extending them with new settings where HLS.js could perform buffer management tasks on either end of the playhead is needed.

The only workaround available now is to flush the buffer manually by triggering an event:
hls.trigger(Hls.Events.BUFFER_FLUSHING, { startOffset: number, endOffset: number | Infinity, type: null | 'audio' | 'video' | 'audiovideo' });.

For QuotaExceededError specifically, it sounds like it's never getting to the final fallback of flushing everything. As a simple fix for this issue, we should flush disconnected forward buffer ranges before it comes to that.

Hi @willdharris,

Could you take a look at #5761? Would setting a frontBufferFlushThreshold resolve this for you?

willdharris · 2023-08-28T17:58:19Z

@robwalch Sorry for the delay. I'll look at this.

@robwalch Yes, this resolves the issue. I was able to test on the problem device, and setting an appropriate frontBufferFlushThreshold keeps us from hitting the QuotaExceededError. Thanks!
