mythfilldatabase fills the Myth database program table with upcoming shows.

Automatic use of mythfilldatabase

Normally mythfilldatabase is run automatically by mythbackend every 24 hours. For most people allowing mythfilldatabase to run automatically will be sufficient, however in areas with no XMLTV grabber or an unusual channel setup it may be run manually.

Manual use of mythfilldatabase

To run an extra time out of sequence (for example, because your subscription had run out, and you just renewed it), use no command line options:

     mythfilldatabase

Command line options

--manual

Run in manual channel configuration mode. This will ask you questions about every channel.

--update

For running non-destructive updates on the database for users in xmltv zones that do not provide channel data.

--preset

Use it in case that you want to assign a preset number for each channel, useful for non US countries where people are used to assigning a sequenced number for each channel, i.e.: 1->TVE1(S41), 2->La 2(SE18), 3->TV3(21), 4->Canal 33(60)...

--file <sourceid> <xmlfile>

Bypass the grabbers and read data directly from a file. <sourceid> = number for the video source to use with this file. <xmlfile> = file to read.

--dd-file <sourceid> <offset> <lineupid> <xmlfile>

<sourceid> = see --file
<offset> = see --file
<lineupid> = the lineup id
<xmlfile> = see --file

--xawchannels <sourceid> <xawtvrcfile>

(--manual flag works in combination with this). Read channels as defined in xawtvrc file given <sourceid> = cardinput, <xawtvrcfile> = file to read

--do-channel-updates

When using DataDirect, ask mythfilldatabase to overwrite channel names, frequencies, etc. with the values available from the data source. This will override custom channel names, which is why it is off by default. This may manage to fix a corrupted channel lineup. You will also likely need to use this switch if your cable company does a channel realignment, once your program listings source catches up.

--remove-new-channels

When using DataDirect, ask mythfilldatabase to remove new channels (those not in the database) from the DataDirect lineup. These channels are removed from the lineup as if you had done so via the DataDirect website's Lineup Wizard, but may be re-added manually and incorporated into MythTV by running mythfilldatabase without this option. New channels are automatically removed for DVB and HDTV sources that use DataDirect.

--do-not-filter-new-channels

Normally MythTV tries to avoid adding ATSC channels to NTSC channel lineups. This option restores the behaviour of adding every channel in the downloaded channel lineup to MythTV's lineup, in case MythTV's smarts fail you.

--graboptions <"options">

Pass options to grabber.

--sourceid <number>

Only refresh data for sourceid given.

--max-days <number>

Force the maximum number of days, counting today, for the grabber to check for future listings.

--only-update-channels

Get as little listings data as possible to update channels.

--refresh

      Each instance of the --refresh option takes one input, and the option can be specified 
      multiple times.  The three named options can be pre-pended by the 'not' parameter, 
      specifying that day should not be pulled.  Numbered days start with today at zero, 
      counting up, and a range can be specified using a dash.
      
      The following example will refresh today, skip tomorrow, and refresh all of next week:
      
      mythfilldatabase --refresh today --refresh nottomorrow --refresh 7-13

--refresh-today

superseded by --refresh as of 0.25, old options will continue to function for now, but will be hidden from the help printout.

--refresh-second

superseded by --refresh as of 0.25, old options will continue to function for now, but will be hidden from the help printout.

--refresh-all

superseded by --refresh as of 0.25, old options will continue to function for now, but will be hidden from the help printout.
(Only valid for grabbers: DataDirect, se_swedb, no, ee, de_tvtoday). Force a refresh today or two days (or every day) from now, to catch the latest changes. These may be used to attempt to fix corrupted program guide data.

--dont-refresh-tomorrow

superseded by --refresh as of 0.25, old options will continue to function for now, but will be hidden from the help printout.
Tomorrow will always be refreshed unless this argument is used.

--dont-refresh-tba

"To be announced" programs will always be refreshed unless this argument is used.

--export-icon-map [<filename>]

Exports your current icon map to <filename> (default: iconmap.xml).

--import-icon-map [<filename>]

Imports an icon map from <filename> (default: iconmap.xml).

--update-icon-map

Updates icon map icons only.

--reset-icon-map [all]

Resets your icon map (pass all to reset channel icons as well).

--mark-repeats

Marks any programs with a OriginalAirDate earlier than their start date as a repeat.

-v or --verbose debug-level

Use '-v help' for level info.

--help

This text.

--manual and --update can not be used together.

External XMLTV

If you are in a country where mythfilldatabase will not work the normal way you will need to use the --file flag (e.g. XMLTV does not have a grabber included, or the grabber options are not fully supported by MythTV).

Obtain xml file of tv guide

Here in Belgium, I use pytvgrab to get my tv guide and output to an xml file:

$ tv_grab_be_tvb --configure  (you only need this the first time)
$ tv_grab_be_tvb -o belgium.xml

Find out the source id of your card

This is normally '1' if you have only one input card, but it is best to check it out because I have found if I have run mythtv setup more than once it can end up being something other than 1. To check, you need to look at the database:

$ mysql -u root mythconverg
mysql> select * from cardinput\G
cardinputid
cardid
sourceid=4
etc.

Remember the source id

Run mythfilldatabase with the --file flag

The --file argument allows to directly import xmltv files. This is useful if you are using programs like nxtvepg to grab your EPG data.

From 0.21 on:

From version 0.21 on the arguments of this command changed. The offset argument has been removed and the command changed to:

$ mythfilldatabase --file <sourceid> belgium.xml

From 0.25 on:

From version 0.25, the arguments of this command changed:

$ mythfilldatabase --file --sourceid <sourceid> --xmlfile belgium.xml


The first time you will need to use the --manual flag, but this is better explained on the XmlTv page.

Troubleshooting

mythfilldatabase causes the system to hang

This is probably an I/O saturation issue. mythfilldatabase and MySQL can cause hard disk or ATA bus saturation, causing Mythbackend to starve. Read more about Troubleshooting:Mythfilldatabase_IO_bottleneck.
