There is a setting whose meaning is not understood.

-playlistAcrossSessions

-Cross-Session Playlist Timeout

Do you know what the two are?

For example, we stream to Akamai at Stream Targets. Can you give an example of how the two functions work?

Sorry for the delay in a response @Hideki Yamaguchi:

A. - **playlistAcrossSessions** :

Indicates whether instance-specific playlists should be maintained across source stream interruptions and app restarts.

B. - **Cross-Session Playlist Timeout** :

The time, in milliseconds, that a cross-session playlist is maintained. The default value is 120000 (2 minutes).

Here is some sample code with both of those on our GitHub:
