Manual use of mythfilldatabase
Command Line Options
Run in manual channel configuration mode This will ask you questions about every channel
For running non-destructive updates on the database for users in xmltv zones that do not provide channel data For example, to update two datasources with a single xmltv file, use : mythfilldatabase --update --file 1 -1 tvguide.xml mythfilldatabase --update --file 2 -1 tvguide.xml See below for help about --file.
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)...
Do not delete old programs from the database until 7 days old.
--file <sourceid> <offset> <xmlfile>
Bypass the grabbers and read data directly from a file <sourceid> = number for the video source to use with this file <offset> = days from today that xmlfile defines (-1 means to replace all data, up to 10 days) <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
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.
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.
Pass options to grabber
Only refresh data for sourceid given
Force the maximum number of days, counting today, for the grabber to check for future listings
Get as little listings data as possible to update channels
(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.
Tomorrow will always be refreshed unless this argument is used
"To be announced" programs will always be refreshed unless this argument is used
Exports your current icon map to <filename> (default: iconmap.xml)
Imports an icon map from <filename> (default: iconmap.xml)
Updates icon map icons only
Resets your icon map (pass all to reset channel icons as well)
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
--manual and --update can not be used together.
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).
1. 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
2. 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
3. Run mythfilldatabase with the --file flag
The -1 means to replace all data, belgium.xml is the file name for the output of the grabber as above:
$ mythfilldatabase --file <sourceid> -1 belgium.xml
The first time you will need to use the --manual flag, but this is better explained on the XmlTv page.
1. LinkSys or Fedora Core
I spent the past 3 weeks trying to troubleshoot a problem I was having with mythfilldatabase. I would run it and it would download between 5K and 3K and then just timeout. If I tried downloading the NVidia drivers, the nVidia page would not even come up.
I found this solution http://www.gossamer-threads.com
which says to do this:
add this line in /etc/sysctl.conf
net.ipv4.tcp_window_scaling = 0
execute sysctl -p /etc/sysctl.conf or restart your computer
Weeks of frustration fixed. Hope this helps someone.
Note from a network techie.... Please be aware that disabling tcp window scaling has a system wide impact and will probably result in much slower bulk transfer speeds. Just thought you should be aware.
2. INSERT IGNORE INTO SQL Errors
If you find in mythfilldatabase's logs something like:
2006-11-21 22:33:22.474 DB Error (Inserting into program table): Query was: INSERT IGNORE INTO program (chanid, starttime, endtime, title, subtitle, description, showtype, category, category_type, airdate, stars, previouslyshown, stereo, subtitled, hdtv, closecaptioned, partnumber, parttotal, seriesid, originalairdate, colorcode, syndicatedepisodenumber, programid) SELECT dd_v_program.chanid, DATE_ADD(starttime, INTERVAL channel.tmoffset MINUTE), DATE_ADD(endtime, INTERVAL channel.tmoffset MINUTE), title, subtitle, description, showtype, dd_genre.class, category_type, airdate, stars, previouslyshown, stereo, subtitled, hdtv, closecaptioned, partnumber, parttotal, seriesid, originalairdate, colorcode, syndicatedepisodenumber, dd_v_program.programid FROM (dd_v_program, channel) LEFT JOIN dd_genre ON (dd_v_program.programid = dd_genre.programid AND dd_genre.relevance = '0') WHERE dd_v_program.chanid = channel.chanid; Driver error was [2/1105]: QMYSQL3: Unable to execute query Database error was: Unknown error
It most likely means your database has become corrupted. To fix the corrupted database run the following command
mysqlcheck -r -u <username> -p <password> mythconverg
3. 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.
