[mythtv-users] Order of transcode and userjobs

[Jason Stone]

Cool thanks...

I'm sure I would have found that if I had looked harder.

I didn't really want to run the svn so I ended up adding the -l as enabled by default (in the source) in mythtranscode so that the cutlist would be enabled.

The order is defined by the code in JobQueue::QueueJobs() in
libs/libmythtv/jobqueue.cpp.

I've been considering making a setting for each of the User Jobs that would
allow you to run a User Job before the transcoder and flagger or between
them, but haven't got around to it.

For your purposes, you can edit JobQueue::QueueJobs() and do something like
move the following 2 lines up to inbetween where the transcode and commercial
flagging jobs get queued:

Move this (move, don't copy, otherwise it could get run twice):

    if (jobTypes & JOB_USERJOB4)
        QueueJob(JOB_USERJOB4, chanid, starttime, args, comment, host);

Up so it gets run between the transcoder and flagger like this:

    if (gContext->GetNumSetting("AutoTranscodeBeforeAutoCommflag", 0))
    {
        if (jobTypes & JOB_TRANSCODE)
            QueueJob(JOB_TRANSCODE, chanid, starttime, args, comment, host);
        if (jobTypes & JOB_COMMFLAG)
            QueueJob(JOB_COMMFLAG, chanid, starttime, args, comment, host);
    }
    else
    {
        // Run the flagger, then User Job #4, then the transcoder
        if (jobTypes & JOB_COMMFLAG)
            QueueJob(JOB_COMMFLAG, chanid, starttime, args, comment, host);
        if (jobTypes & JOB_USERJOB4)
            QueueJob(JOB_USERJOB4, chanid, starttime, args, comment, host);
        if (jobTypes & JOB_TRANSCODE)
            QueueJob(JOB_TRANSCODE, chanid, starttime, args, comment, host);
    }

If you really trust the flagger that much and are using SVN, then you can
use the new settings I just added tonight that allow you to specify the
command to run for mythtranscode.  You could just tell Myth to run the
following for transcoding instead of the default command:

	/path/to/your/bin/directory/mythtranscode -j %JOBID -V %VERBOSELEVEL% -p %TRANSPROFILE% -l

The '-l' is the only thing different than the command that would normally
get run by the JobQueue.  "-l" tells mythtranscode to apply the cutlist and
this option is only passed to mythtranscode when you manually schedule a
transcoding job, not when one runs automatically.  The setting is on the
JobQueue global settings page in mythtv-setup.
