Interrupting buffering with `stopLoad()` and then restarting with `startLoad()` causes a transition to the lowest level #5230

What version of Hls.js are you using?

1.3.3

What browser (including version) are you using?

What OS (including version) are you using?

Debian 9

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://hls-js.netlify.com/demo and not just on my page
The issue occurs in the latest client (main branch) on https://hls-js-dev.netlify.com/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 hls-js.netlify.com/demo and open the chrome devtools
While the stream is still buffering, call hls.stopLoad() in the console. Notice the level of the fragments being buffered (for me it starts at level 3, then goes up to level 4).
Now call hls.startLoad() to resume buffering. Notice that the level switches down (for me, it switches down to level 2), then slowly switches back up again.

Expected behaviour

I would not expect any level switching to take place after I call hls.startLoad(), since nothing about my bandwidth or streaming capabilities have changed. It seems like manually stopping + starting the load is messing with the automatic level switcher.

What actually happened?

When I call hls.stopLoad() and then hls.startLoad(), the video level switches dramatically downward (from 4 -> 2 in my case).

When I call hls.stopLoad() and then hls.startLoad(), the video level switches dramatically downward (from 4 -> 2 in my case).

After calling hls.stopLoad() and then hls.startLoad(), the player restarted loading the same fragment at the same level as the one that was interrupted (note two lines that read Loading fragment 2 cc: 0 of [0-63] level: 4, target: 19.992 before and after).

Only after buffering that fragment, the player then logs a down switch. I see there was a drastic change is estimate. Looking into root-cause.

robwalch · 2023-02-18T16:51:35Z

I missed it on the first try, but after a careful review of step 2, used hls.once(Hls.Events.FRAG_LOADING, () => hls.stopLoad()); to interrupt loading.

With trace logs enabled I see that before the restarting and rebuffering the fragment that was interrupted, estimates look OK:

[trace] > [abr] level:4 adjustedbw-bitrate:117164970 avgDuration:9.9 maxFetchDuration:30.8 fetchDuration:0.9

But then we get a rude awakening right after buffering the fragment that was interrupted:

[log] > [stream-controller]: Buffered main sn: 4 of level 4 (frag:[40.008-50.023] > buffer:[0.023-49.993])
[trace] > [abr] level:4 adjustedbw-bitrate:-6221600 avgDuration:9.9 maxFetchDuration:33.7 fetchDuration:191156308873128.2

Best guess is that LoaderState (stats )or some other loader state are not being reset. Need to dig deeper. Thanks for the report.

robwalch · 2023-02-18T19:30:05Z

The is issue is that when startLoad is called, the current level's Playlist is reloaded, replacing stream-controller's LevelDetails with a new fragment list containing new Fragment references and stats. When this happens while the fragment is being loaded, the reference frag.stats used to tally loading/parsing/buffering times is replaced. The default start values of 0 and produce bad results here https://github.com/video-dev/hls.js/blob/master/src/controller/abr-controller.ts#L296

Fix prevents the playlist from being reloaded when it does not need to be, and uses the correct fragment object reference for continuity in the event it would not be (this had been fixed for live where fragment lists are merged, but we never expect to replace loaded playlist data for VOD) e49ff5c
