Are you talking about how long it takes for the connection / socket to 
close on the system?  (I.e. netstat / ss show the connection.)

(For the sake of conversation, I'm assuming that I'm correct.)

If a video finishes it's playback and the player realizes that the video 
stream is finished, the player can issue the proper sequence to close 
the connection.  Where as if the player is in the middle of a stream and 
the data stops, the player will likely wait for a timeout (coded in the 
player) before giving up and aborting the playback.

I don't know that there is much that you can do other than trying to 
close the connection (TCP Reset / ICMP Host Unreachable / etc.) to 
artificially cause the player to terminate playback early.
