Playback stall (resolving "waiting" event) regression starting v1.7.0

[rxnniiee]

What version of HLS.js are you using?

v1.7.3

What browser (including version) are you using?

Microsoft Edge 153.0.4234.32 (Official build) (64-bit), Google Chrome 152.0.7977.83 (Official Build) (64-bit), Firefox 155.0.1 (64-bit)

What OS (including version) are you using?

Windows 11

Test stream

should be able to grab the stream.m3u8 here (ipcamlive stream, url can change): https://esteve.ee/veebikaamera/

Configuration

{
  "debug": true,
  "enableWorker": true,
  "lowLatencyMode": true,
  "backBufferLength": 90
}

Additional player setup steps

No response

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. Play stream on affected version
2. Observe broken behaviour

Expected behaviour

Smooth playback like on prior versions. Last version where this particular stream was working perfectly was 1.6.19

What actually happened?

On chromium browsers, the stream seems to play a few frames and then freeze for about 2 seconds, the cycle will repeat forever. on versions prior to 1.7.0-1.7.3 the stream plays without issues.
On Firefox it seems that it plays a few frames and then keeps glitching and never playing anything after that.

Chrome media internals output

[robwalch]

We'll have to see which changes in MPEG2-TS remuxing impacted smooth playback of this specific video-only content. Chrome is issuing "waiting" events despite the buffer being full with no gaps, and/or the rendering pipeline stalls (video freeze) for approximately one gop. Maybe a timestamp rounding issue.

[robwalch]

Tracked this down to a03d5b1. The remuxed media segments are unchanged, but there is a change in init segment SPS output. Chrome media panel shows a decode error handling by a fallback from VideoToolboxVideoDecoder to FFmpegVideoDecoder, only present in v1.7+:
