- Timers are now sorted in the "Timers" menu, showing the sequence in which
they will be recording. This can be disabled in the "Setup" menu. Note
that the "Mark" button doesn't work if timers are displayed sorted.
2001-09-01: Version 0.9.4
- Changed version number notation.
- Implemented automatic shutdown (see INSTALL and MANUAL for details).

VDR will go into 'deamon' mode and the initial program call will return
immediately!
Automatic shutdown:
-------------------
If you define a shutdown command via the '-s' command line option, VDR
will call the given command if there is currently no recording or replay
active, the user has been inactive for at least MinUserInactivity minutes
and the next timer event is at least MinEventTimeout minutes in the future
(see the Setup parameters in MANUAL).
The command given in the '-s' option will be called with two parameters.
The first one is the time (in UTC) of the next timer event (as a time_t
type number), and the second one is the number of seconds from the current
time until the next timer event. Your program can choose which one to use
for programming some sort of hardware device that makes sure the computer
will be restarted in time before the next timer event. Your program must
also initiate the actual shutdown procedure of the computer. After this
your program should return to VDR. VDR will not automatically exit after
calling the shutdown program, but will rather continue normally untit it
receives a SIGTERM when the computer is actually shut down. So in case
the shutdown fails, or the shutdown program for some reason decides not to
perform a shutdown, VDR will stay up and running.
Before the shutdown program is called, the user will be prompted to inform
him that the system is about to shut down. If any remote control key is
pressed while this prompt is visible, the shutdown will be cancelled (and
tried again after another MinUserInactivity minutes). The shutdown prompt
will be displayed for 5 minutes, which should be enough time for the user
to react.
A sample shell script to be used with the '-s' option might look like this:
#!/bin/sh
setRTCwakeup $(($1 - 300))
sudo halt
Here 'setRTCwakeup' would be some program that uses the first parameter
(which is the absolute time of the next timer event) to set the Real Time
Clock so that it wakes up the computer 5 minutes (i.e. 300 seconds) before
that event. The 'sudo halt' command then shuts down the computer.
You will have to substitute both commands with whatever applies to your
particular hard- and software environment.

you may want to use smaller values if you are planning
on archiving a recording to CD.
MinEventTimeout=120 If the command line option '-s' has been set, VDR will
MinUserInactivity=120 automatically shutdown the computer if the next timer
event is at least MinEventTimeout minutes in the future,
and the user has been inactive for at least
MinUserInactivity minutes. Setting MinUserInactivity
to 0 disables the automatic shutdown, while still
retaining the possibility to manually shutdown the
computer.
