Additional player setup steps

Checklist

Steps to reproduce

  1. Set capLevelToPlayerSize to true in your config
  2. Start playing your video
  3. Try to resize your window multiple (e.g. resize your window from large to small and then small to large in row and fast)

Expected behaviour

I expect that when I set capLevelToPlayerSize to true and resize my player, hls.js choose correct level and does not freeze or stalled but currently when user do such a behaviour for any reason, it stalled!

What actually happened?

Some of our user reported that our player after instant resizing freezes and get stock at stalled status. After several tests we recognized that when capLevelToPlayerSize is true this issue happens.

Worth to mention that:

Hi @aminghorbankhani,

The logs show that your page is reloading and resetting the buffer (not HLS.js):

Media is completely buffered:

[stream-controller]: Buffered main sn: 6 of level 2 (frag:[10.008-10.200] > buffer:[0.080-10.101])
[stream-controller]: PARSED->IDLE
[buffer-controller] audio sourceBuffer now EOS
[buffer-controller] video sourceBuffer now EOS
[buffer-controller] Queueing mediaSource.endOfStream()
[stream-controller]: IDLE->ENDED
[buffer-controller] Calling mediaSource.endOfStream()
[buffer-controller] Media source ended

The page is reloading the resource which resets the buffer:

player.jsx:1695 [log] > loadSource:https://www.example.com/waa64ay.m3u8?k=90e0c

This appears to be an issue with the integration of hls.js. I cannot reproduce the issue using the demo page with the provided configuration and any of the sample assets.
