Interrupt loading once the segment list is retrieved. Loading can be started at the start time of any segment in the list:

// begin loading playlists with a callback for the first variant playlist
// containing the last of segments (`details.fragments`):
const hls = new Hls({});
hls.loadSource('https://host/index.m3u8');
hls.attachMedia(hlsVideo);
hls.once(Hls.Events.LEVEL_UPDATED, (name, data) => {
  // set the start position using startLoad to skip loading of the first segment 
  const fragments = data.details.fragments;
  const startTime = fragments[1].start;
  hls.startLoad(startTime);
});

Hi, thanks so much! I've been working on a solution for that. I was able to fix it by changing the value of liveSyncDurationCount.

The value was 8, and I set it to 0, which made it start consuming the second segment from the first playlist exactly as I needed.

Now I'm wondering if my solution is the best approach, since your solution seems better. What do you think?

I was able to fix it by changing the value of liveSyncDurationCount

I did not notice that you were working with a live playlist. Live playlists should be at least three segments long and liveSyncDurationCount should be set to at least three.

Alternatively, you can set liveSyncDuration to 2.5x the segment or target duration.

Those guidelines work best with 4-10 second target durations. If you insist on using two second segments, you should at least double the number of segments in your sliding window and hold back an addition segment to maintain steady playback.

Sorry for the delay in responding; I have many Jira tickets to work on...

Live playlists should be at least three segments long and liveSyncDurationCount should be set to at least three.

Is there a best practices manual for configuration/delay that I can read?

Regarding holding an additional segment, I didn’t understand what you meant. Could you provide an example?

Thank you for your attention. ✋🏾

hold back an addition segment

I mean hold back the playhead one additional segment duration from the end of the playlist.

So if you have 2 second segments, the playlist should be at least 6 segments long and playback should start 3 or more segments from the end (as apposed to only 2.5).

Oh I got it!
Thanks again @robwalch
