Here are the notes that I used to get my EPG using Stephen Worthington’s mhegepgsnoop.py<\/a><\/h3>\n

These are the notes that I used when I first setup my system:-<\/h3>\n

1) Download\u00a0tv_grab_nz-py\u00a0from\u00a0http:\/\/nice.net.nz\/tv_grab_nz-py\/<\/a><\/p>\n

2) Copy\u00a0tv_grab_nz-py\u00a0to \/usr\/local\/bin.\u00a0 Make sure that it
\nis executable. (sudo chmod +x tv_grab_nz-py)

3) Configure it. Note that the configuration file name must match that\u00a0
name of the video source configured in mythtv-setup for the\u00a0
mythbackend\/mythfilldatabase to use this grabber.\u00a0
tv_grab_nz-py\u00a0–configure –config-file ~\/.mythtv\/<video sources
\nname>.xmltv
\nStep 3 had some problems for me but it was overcome by copying and editing
\nanother <video sources name>.xmltv<\/p>\n

You also need to symlink otherwise mythfilldatabase will not work
\nautomatically (it uses the user mythtv)
\nsudo ln -s \/<\/span>home\/yourusername\/<\/span><\/i>.mythtv\/Freeview.xmltv \/<\/span>home\/mythtv\/<\/span><\/i>.mythtv\/Freeview.xmltv
\n
4) To see if the xmltv side of things works run\u00a0
tv_find_grabbers\u00a0

This should return a list of all the installed grabbers, which should\u00a0
include tv_grab_nz-py.\u00a0

5) To see if the myth side of things works run\u00a0
mythfilldatabase\u00a0
Pay close attention to the output of this. If it looks like it worked,\u00a0
the MythWeb status page should also show a successful run.\u00a0

6) On the master backend run mythsetup and\u00a0
a) In Video Sources set “New Zealand (py)” as the grabber for your\u00a0
Video Source.\u00a0
b) In General, on the Mythfilldatabase page (its the last page) enable\u00a0
“Automatically run mythfilldatabase”. Configure time, frequency, etc\u00a0
to suite. Now Myth should use\u00a0tv_grab_nz-py\u00a0to update EPG\u00a0
periodically. The MythWeb status page shows when it was last run and\u00a0
what the results were.<\/p>\n

After installing MythBuntu 16.04 had had
\ntwo problems:-<\/span>
\nMythweb fails with mysql Server version: 5.7.11-0ubuntu5
\nI found this\u00a0
https:\/\/code.mythtv.org\/trac\/ticket\/12713<\/a>\u00a0
Which suggested editing \/etc\/mysql\/conf.d\/mythtv.cnf\u00a0
to\u00a0
[mysqld]\u00a0
#bind-address=0.0.0.0\u00a0
max_connections=100\u00a0
sql_mode=NO_ENGINE_SUBSTITUTION\u00a0

This seems to have mythweb working OK.
\nI also had this problem *Mythbuntu 16.04 Fresh Install – always starts
\nMythTV Setup on boot *
\nand found this http:\/\/www.gossamer-threads.com\/lists\/mythtv\/users\/601385<\/a><\/p>\n

and this https:\/\/ubuntuforums.org\/showthread.php?t=2320224<\/a><\/p>\n

The fix for me was…
\nShort version of solution that worked for me:
\ncopy \/lib\/systemd\/system\/mythtv-backend.service to \/etc\/systemd\/system\/
\nedit \/etc\/systemd\/system\/mythtv-backend.service and insert the line
\nExecStartPre=\/usr\/bin\/nm-online –quiet –timeout=5 above the existing
\nExecStartPre=… line.
\nreboot<\/p>\n

\n

How
\nto secure Mythweb<\/a><\/p>\n

\n

Mysql password<\/span> can be found in
\n\/home\/mythtv\/.mythtv\/config.xml
\n
\nWhen changing password it must be done in the following:-
\nmysql, \/etc\/mythtv\/config.XML
\nand \/etc\/apache2\/sites-available\/mythweb.conf
\nand front-end setup.<\/b><\/b><\/b><\/b><\/b><\/p>\n

\n

To change to Schedules Direct grabber:-<\/h3>\n

0.<\/span>\u00a0 Back everything up first!<\/p>\n

1.<\/span> Sign up for an account on www.schedulesdirect.org<\/a> and follow the instructions
\nlinked to above to get your 90 day voucher.<\/p>\n

2.<\/span> Activate XMLTV updates repo and
\nupdate. (I use MythBuntu Control Centre for this. May not be available on
\nother distros)<\/p>\n

3.<\/span>\u00a0 Verify that the Schedules
\ndirect JSON module is now a recognised grabber:
\ntv_find_grabbers<\/p>\n

should find: \/usr\/bin\/tv_grab_sd_json|Schedules Direct JSON API<\/p>\n

4.<\/span> \u00a0configure your Schedules
\ndirect grabber
\ntv_grab_sd_json –configure<\/p>\n

Follow the on screen prompts.\u00a0 I chose to use a “channels” config,
\nrather than a “lineup” config because I wanted a more fine-grained control
\nover my listings.\u00a0 I don’t know whether this is worthwhile or not.
\nYMMV. Our country code is NZL<\/p>\n

This creates a .conf file in your ~\/.xmltv folder
\nI then copied as follows:-
\nsudo cp ~\/.xmltv\/tv_grab_sd_json.conf ~\/.mythtv\/SchedulesDirect.xmltv
\nand
\nsudo cp ~\/.xmltv\/tv_grab_sd_json.conf
\n\/home\/mythtv\/.mythtv\/SchedulesDirect.xmltv
\nthen edit the cache line in \/home\/mythtv\/.mythtv\/SchedulesDirect.xmltv
\nto
\ncache=\/home\/mythtv\/.xmltv\/tv_grab_sd_json.cache<\/p>\n

If the cache line is not edited mythfilldatabase, when run with user mythtv
\nwill give error…..
\nFAILED: XMLTV grabber returned error code 13<\/p>\n

The name of the xmltv file should match the name of the Video Source that
\nyou set up in step 5 below. (e.g. SchedulesDirect.xmltv)<\/p>\n

5.<\/span> Add new video source(s) in
\nmythtv-setup
\nSet the “listings grabber” field to “Schedules Direct JSON API (xmltv)”
\nYou also need a unique video source name that matches the symbolic link name
\nthat you created in step 4 above.\u00a0 Do not click configure.\u00a0 Do not
\ncheck the “use EIT” box.
\n6.<\/span> Input connections
\nConnect your existing capture cards to the video sources that you just
\ncreated.\u00a0 You should not need to scan for new channels or do any other
\nconfiguration here.\u00a0 Do not fetch channels from listing source.
\n7.<\/span> Channel editor.
\nYou need to enter the Schedules Direct Channel ID in the “XMLTV ID:” field.
\n(It can be done in Mythweb)
\nYou can get this info by running
\ntv_grab_sd_json | grep -A1 ‘<channel id=”‘ > output.txt<\/p>\n

\n

To get the latest EPG data from Schedules direct…..(one line)
\nrobert@FishMyth:~$ \/usr\/bin\/tv_grab_sd_json –config-file
\n\/home\/robert\/.xmltv\/tv_grab_sd_json.conf –output \/tmp\/sd.xml<\/p>\n

\n

Icons<\/span> go in the
\n~\/.mythtv\/channels folder.\u00a0 It’s usually a good idea to empty
\nthe\u00a0\/var\/cache\/mythweb\/image_cache\/ folder before updating icons.<\/p>\n
