[mythtv-users] Shutdown / Idle Commands Clarification

[Michael Watson]

There are a myriad of commands related to the shutdown, idle status of 
Myth Backend and Frontend, can anybody explain fully there use, expected 
return values if any, and under what conditions are each run.

The reason I ask is, I am trying to make a SBE/FE (With 1 Tuner) to 
shutdown when not in use.  Whilst I have it working, it is not working 
as efficiently as it could.

1. Using MythWelcome, the SBE/FE will not shutdown until the entire 
system is idle.  ie; All comercial flagging must be complete, and no 
recordings to start on any backend in the near future.

2. Using the frontend idle settings, the SBE/FE will shutdown whilst 
playing music, or immediately after watching a move or recorded program  
(It thinks its idle because no key presses have been made in the defined 
idle time, idle time is not reset whilst playing music or watching a 
recording)

3.  If I use the Backend Sleep command, with a "smart" script that 
checks if frontend is running, screen saver active, it is only called 
once, when the MBE decides that the SBE is idle and ready to shutdown.  
It appears that it does not accept a return value to say shutdown 
failed, retry later or I have not found the correct return value.

So, if someone could explain what the intended use for the following 
options, and under what conditions they are to called/executed, might 
solve my problem.


*mythtv-setup*

Server Halt Command
Pre-Shutdown-Check Command
Sleep Command
Backend Stop Command
Backend Start Command

*mythfrontend*

Halt Command
Reboot Command
