Additional player setup steps

hls.on(Hls.Events.MANIFEST_LOADED, (event, data) => {

if (stats && stats.parsing) {

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

Steps to reproduce

1. Load a master HLS manifest using Hls.js.
2. Bind a listener to the MANIFEST_LOADED event.
3. Inspect the stats object provided in the event callback.
4. Observe that stats.parsing.start is set, but stats.parsing.end is zero.

Additional notes:

• For a media playlist (level), both parsing.start and parsing.end are set as expected.
• This behavior is consistent and occurs every time a master manifest is loaded.

Expected behaviour

Expected behaviour

• stats.parsing.end should also be set for master playlists, just like it is for media playlists (levels).
• This would make the parsing stats consistent and allow proper performance tracking for all types of playlists.

What actually happened?

What actually happened?

• When loading a master playlist, stats.parsing.start is set, but stats.parsing.end remains zero.
• For media playlists (levels), both parsing.start and parsing.end are correctly set.
• This creates an inconsistency in the stats reporting, making it difficult to track parsing performance for master playlists.

parsing.start: 5246.0999999940395
