mythexport does not keep Userjob open until ffmpeg transcode is complete

[Stefan Pappalardo]

Binary package hint: mythexport

When adding a recording to the job queue mythexport reports the job as started und finished at the same second.

There is no starting and finishing entry in the /var/log/mythtv/mythexport.log

But the job runs and finishes correctly, if mythshutdown does not shutdown automatically :-(

Try enabling debugging (see the wiki), and make sure your ffmpeg lines are executing correctly. Feel free to pastebin or post your configs and logs.

Please always attach (or if small, paste) configs and logs directly to
tickets. This eliminates a few risks:

* the information going away before someone can look at it (pastebin
is not a permanent warehouse)
* information not being available for reference in the far future
* getting the logs into the ticket (if someone makes a mistake while
downloading from pastebin and uploading to the ticket)

I try it again:

The job runs and finishes correctly, if mythshutdown does not shutdown automatically. So how should there
something wrong with the ffmpeg lines? (see attached mythexport_settings.cfg and above you can see the log.)

In my opinion a mythexport job should stay in status "running" until it is finished. But it doesn't. It gets reported started and finished at the same second (see above).

What do you need exactly? Which logfile or something?

[Steve Switzer (steve-switzer)]

Please post a section of the /var/log/mythtv/mythexport.log file that occurs when you trigger this. I think this is related to a recent bug report of mine, but am curious to see for sure.

Just spoke to John Baab on irc about this issue.

 After starting the userjob, mythtranscode runs the lossless transcode to cut the commercials (i.e. -honorcutlist) and outputs to a .mpg.tmp file, once that completes the job shows as successful even though the ffmpeg portion of the job hasn't completed. The ffmpeg portion runs fine, but since this is a combined frontend/backend I'd like it to shut down after its finished transcoding, with the userjob showing completed it would shut down while ffmpeg is still running.

He proposed reusing the id from the sql table and make a unique file which would be created when the User Job starts and deleted when the ffmpeg portion of the transcode completes. That way the User Job would stay open until the entire process completes and mythbackend wouldn't shutdown until the transcoding is complete.

I have pushed the fix for this bug to the Mythbuntu Testing PPA:

Please leave any feedback if you are able to test it.
