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

1. Start playback of hls live stream

Expected behaviour

Playback should happen seamlessly

What actually happened?

Playback stops after a while without error. m3u8 files keep downloading, but no ts file is downloaded.

NOTE: Playback works on other browsers and platforms without issue.

Looks like stream-controller went into a PARSED state and never left that state:

[log] > – "[stream-controller]:" – "PARSING->PARSED" (hls.min.js, line 1)

It is expected that parsed media will be appended (calling fragBufferedComplete) and that that will return the stream-controller to the PARSED->IDLE state to load the next segment.

If this happens on other devices and browsers check your stream's validity, and share a sample that can be used to repro the issue.

If the issue is specific to the device you are testing on you'll need to add some logs or do some debugging in buffer-controller starting with onFragParsed and following through blockBuffers for append and the operation queue. These lines in particular can be uncommented to follow whether MSE appends behave as expected: https://github.com/video-dev/hls.js/blob/master/src/controller/buffer-controller.ts#L365-L369

I can see that just before the playback stops, video buffers updatestart event is not followed by updateend.

Adding Revisit-at-later-release-cycle Will revisit during release cycle indicated by the Milestone label. We should consider adding a timeout with error handling for append update events. This appears to be a violation of the MSE spec, and may be related to issues in the asset or application memory usage. Regardless, hls.js should handle known platform/API issues with satisfactory logging and retry or fatal error behavior.
