Is it possible to reduce latency from safari or quicktime to cmaf low latency hls playback URL?

I made a play URL based on cmaf ll-hls in wowza.

In the html5 player and the chrome hls player, it was seen that the latency was applied for 4 to 5 seconds.

However, the latency of safari, quicktime is still applied for 12 to 18 seconds.

Can’t save latency on default browser and quicktime with ccmafl-hls play url?

Or am I making the m3u8 wrong and it doesn’t apply?

(safari 15.1 version , mac)

Any help would be greatly appreciated… I’ve been struggling for 2 months.

Below is the m3u8 that I made.

If the m3u8 file is wrong, please let me know why it is wrong

I’d appreciate it if you could recommend an ios native app to test the cmaf ll-hls playback URL generated by wowza.

If safari, quicktime basically doesn’t apply cmaf ll-hls, I’d really appreciate it if you could let me know what options or tasks I need to do when I develop an ios player.
