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

Try on short video or close to end so that end of stream is being fired

1. pause the video
2. click next level loaded with different quality
3. play video
4. repeat steps 1-3 until u see duration value blink and durationchange event being fired few times firstly with current time value

Expected behaviour

Duration does not change after switching nextLevel on paused video.

What actually happened?

In my implementation I switch quality on paused video cause settings board overlaps video element. When i switch quality few times in a row there is an issue that duration of the video changes to current time and updates with buffer appends.

Hi @kwalasik07,

Are you able to reproduce this in v1.6.0-beta.1 (or dev https://hlsjs-dev.video-dev.org/demo/)?

I reproduced it in v1.5.x. It happens when mediaSource.endOfStream() is called out of sequence, when setting nextLevel while buffered to the end.

hls.js/src/controller/buffer-controller.ts

Lines 1065 to 1067 in 1e7fbe1

	this.log(`Calling mediaSource.endOfStream()`);
	// Allow this to throw and be caught by the enqueueing function
	mediaSource.endOfStream();

It appears to be fixed in dev.
