User Jobs are programs which can act on MythTV recordings. A MythTV system currently supports four User Jobs.
Adding a User Job
There are three ways to add a User Job into the system:
1) In the mythtv-setup program (pages 7 & 9 of the General button)
2) By using some SQL statements to insert the job directly. For example, a hypothetical job which edits bad language:
% mysql mythconverg UPDATE settings SET data='/path/to/rm-swearing.sh %DIR%/%FILE%' WHERE value='UserJob1'; UPDATE settings SET data='Swearing Removal' WHERE value='UserJobDesc1'; UPDATE settings SET data='1' WHERE value='JobAllowUserJob1';
3) By using Mythweb Settings | MythTV settings table and editing
UserJob# & UserJobDesc#
Important Note: If you use the MythWeb version or manual mysql version for setting up a user job, you have to restart mythbackend for the changes to take effect. Theoretically if you are doing it via MythTV-Setup, then mythbackend isn't running anyway.
User Job arguments
A user job is just a program or script which is passed some arguments to tell it what recording to perform work on. Either the channel and start time, or the directory and filename, should be sufficient to uniquely identify the recording.
Option | Description |
---|---|
%CHANID% | Channel ID |
%STARTTIME% | Start Time of the Recording |
%DIR% | Path to the recording directory |
%FILE% | The file name |
%TITLE% | |
%SUBTITLE% | |
%DESCRIPTION% | |
%HOSTNAME% | |
%CATEGORY% | |
%RECGROUP% | |
%PLAYGROUP% | |
%STARTTIME% | In the format yyyyMMddhhmmss |
%ENDTIME% | |
%STARTTIMEISO% | In the ISO date format YYYY-MM-DD hh:mm:ss |
%ENDTIMEISO% | |
%PROGSTART% | |
%PROGEND% | |
%PROGSTARTISO% | |
%PROGENDISO% | |
%VERBOSELEVEL% | |
%JOBID% | The id of this job in the mythconverg jobqueue table |
Information on completion percentage of a running job, and on results of a completed job, is stored in the comment column of the jobqueue table in the mythconverg database.
User Job Examples
Command | Description |
