Ihry,

This reading may answer your last post:

streamlink -h

--player-no-close
By default Streamlink will close the player when the stream ends.
This is to avoid "dead" GUI players lingering after a stream ends.

It does however have the side-effect of sometimes closing a player
before it has played back all of its cached data.

This option will instead let the player decide when to exit.


--player-continuous-http
Make the player read the stream through HTTP, but unlike
--player-http it will continuously try to open the stream if the
player requests it.
