Although I haven't actually used it in quite a while, I did setup a
custom transcoding script under mythtv 0.22. As I recall, the problem
is that the transcoding job is responsible for updating the job status
information in the database. Looking at my code, when I finish
successfully, I execute the following query:

UPDATE jobqueue SET status=272, comment='Done' WHERE id=<JOBID>

The value of <JOBID> would be passed into your script as one of the
command line parameters. For instance, my setting for
JobQueueTranscodeCommand is:

/usr/local/scripts/transcode_wrap %JOBID% %CHANID% %STARTTIME% %DIR%
%FILE% "%TITLE%" "%SUBTITLE%" %TRANSPROFILE%


I also don't know if there is a better, more official way to do it,
but this has worked fine for me in the past.


You can also periodically provide updated progress messages as the
script runs by setting status to 4 and setting comment to your
message. That message will then show up when you view the job in
mythfrontend or mythweb.
