I remember, reading your post, but not the followups. So the short
answer is no according to Dean.
I kind of solved it for now. My user job in Myth looks now like this
echo "/usr/bin/nice -n 19 /usr/local/bin/handbrake_userjob.sh
%DIR%/%FILE% /home/mythtv/Videos/TV/ %CHANID% %STARTTIME%" >>
Then I wrote a script which runs when the mythtv user logs in
COMMAND=`head -n 1 ~/.mythtv/jobqueue`
sed -i 1d ~/.mythtv/jobqueue
if [ $ERROR -gt 0 ]
echo "userjob $COMMAND unsuccessful"|mail your.em at il.address
This takes the first line of the file, executes it and deletes that
line. If there is a problem with the userjob I'll get an email about it.
The sleep value should be greater than the "idle shutdown timeout",
otherwise the backend will never shutdown as long as there are jobs in
You'll also need your own "Pre-shutdown-check command" which checks
whether a userjob is running or not. Something like
pidof -x handbrake_userjob.sh || ERROR=1
mythshutdown --check || ERROR=1
The downside is that I don't see the running userjob in mythweb or
mythtvfrontend. I couldn't find a way to add a userjob to Myth from the
command line. I searched the database and didn't se any references of
running/queued jobs in it, only completed ones.
