Is there a way to run a script just before a recording starts and

I don't know how to trigger scripts when a recording starts, and
managing sequential recordings would be a problem because you could end
up with a race condition. It would be easier to use a cron job that
parses http://localhost:6544/xml once per minute and looks for the
appropriate tuner status:
$ lynx -dump http://localhost:6544/xml | head -n 5
<!DOCTYPE Status>
<Status version="0.18.1.20050510-1" protoVer="15" time="6:15 AM"
date="11/22/2005" >
<Encoders count="1" >
<Encoder local="1" connected="1" id="1" state="0" lowOnFreeSpace="0"
hostname="linuxbox" />
</Encoders>
You would want to look for the appropriate "Encoder" record and toggle
the external program based on the state field.
That could work, but it's a bit expensive and inelegant.
If it were possible to run a shell script when a recording starts and
ends, the end script could use your method to check if there is an
imminent recording and not restart Athcool if there is, that would fix
the potential race condition you highlighted.
you could just hijack the channel change "script" functionality and
create a user job when the recording completes. The problem of
back-to-back recordings is still possible. maybe some clever file
locking scheme between a channel change (start) and user job (end) could
do the trick.
That's not a bad idea, the other one that occurred to me is doesn't myth
un-mute the line in at the commencement of a recording and re-mute it at
the end? Presumably the race condition has been fixed in that script
already.
