Configuration

{
  "debug": true,
  "startLevel": 0,
  "capLevelToPlayerSize": true
}

Additional player setup steps

• Set HTML video element width to 240px
• Load stream

Alternatively, without the config:

• Load stream
• Pause
• Manually select lowest rendition

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. Load the provided stream
2. Manually select lowest resolution
3. Pause the video

Expected behaviour

Buffer size should be restricted on QuotaExceededError.

What actually happened?

Due to playing very low bitrate video, the audio buffer overfills before reaching the limits of the video buffer. This leads to repeated QuotaExceededErrors: Failed to execute 'appendBuffer' on 'SourceBuffer': The SourceBuffer is full, and cannot free space to append additional buffers. being triggered, and the last audio segment being repeatedly downloaded.

Console output

Clipped as it's infinitely repeating.

I can reproduce the issue and will work on a fix to patch the latest release.

In the meantime, setting maxMaxBufferLength to a reasonable length (say 300) or reducing maxBufferSize (to 20000000 bytes) will prevent the video buffer from exceeding a length that the audio buffer cannot reach at its bitrate.
