[FFmpeg-user] ffmpeg background

[focus television]

Hi,
  Can u tell me how to run the ffmpeg in background.
I dont want to stop the play when i close my shell.
Can i  do something that keeps the process alive even if i close the shell.
I am new to linux and need to use ssl login.
  Can I make a play list so that the videos keep on playing for live 
channels for demo as live channel?
I created a .sh file with same commands like ffmpeg 5 times but not sure 
if it is the right way
