This script can be run from the command line, or called through the mythtv

jobqueue.  The input format will be:
+
  mythvidexport.py [options] <--chanid <channel id>> <--starttime <start time>>
+
                --- or ---
+
  mythvidexport.py [options] %JOBID%
+
 
+
Options are:
+
        --mformat <format string>
+
        --tformat <format string>
+
        --gformat <format string>
+
            overrides the stored format string for a single run
+
        --listingonly
+
            use EPG data rather than grabbers for metadata
+
            will still try to grab episode and season information from ttvdb.py
+
        --seekdata            copy seek data from recording
+
        --skiplist            copy commercial detection from recording

        --cutlist              copy manual commercial cutlist from recording

Important.png Note: The correct title of this article is mythvidexport.py. It appears incorrectly here due to technical restrictions.


Author Raymond Wagner
Description A python script intended to be run as a user job allowing for exporting recordings into MythVideo.
Supports Version25.png  Version26.png Version27.png 


This python script is intended to function as a user job, capable of exporting recordings into MythVideo.

This script can be run from the command line, or called through the mythtv
jobqueue.  The input format will be:
  mythvidexport.py [options] <--chanid <channel id>> <--starttime <start time>>
                 --- or ---
  mythvidexport.py [options] %JOBID%

Options are:
        --mformat <format string>
        --tformat <format string>
        --gformat <format string>
            overrides the stored format string for a single run
        --listingonly
            use EPG data rather than grabbers for metadata
            will still try to grab episode and season information from ttvdb.py
        --seekdata             copy seek data from recording
        --skiplist             copy commercial detection from recording
        --cutlist              copy manual commercial cutlist from recording

Additional functions are available beyond exporting video
  mythvidexport.py <options>
        -h, --help             show this help message
        -p, --printformat      print existing format strings
        -f, --helpformat       lengthy description for formatting strings
        --mformat <string>     replace existing Movie format
        --tformat <string>     replace existing TV format
        --gformat <string>     replace existing Generic format
