My MythTV notes

These are the notes that I used when I first setup my system:-

1) Download tv_grab_nz-py from http://nice.net.nz/tv_grab_nz-py/ 2) Copy tv_grab_nz-py to /usr/local/bin. Make sure that it is executable. (sudo chmod +x tv_grab_nz-py)

3) Configure it. Note that the configuration file name must match that
name of the video source configured in mythtv-setup for the
mythbackend/mythfilldatabase to use this grabber.
tv_grab_nz-py --configure --config-file ~/.mythtv/<video sources name>.xmltv Step 3 had some problems for me but it was overcome by copying and editing another <video sources name>.xmltv You also need to symlink otherwise mythfilldatabase will not work automatically (it uses the user mythtv) sudo ln -s /home/yourusername/.mythtv/Freeview.xmltv /home/mythtv/.mythtv/Freeview.xmltv
4) To see if the xmltv side of things works run
tv_find_grabbers

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

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

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

After installing MythBuntu 16.04 had had two problems:- Mythweb fails with mysql Server version: 5.7.11-0ubuntu5 I found this
https://code.mythtv.org/trac/ticket/12713
Which suggested editing /etc/mysql/conf.d/mythtv.cnf
to
[mysqld]
#bind-address=0.0.0.0
max_connections=100
sql_mode=NO_ENGINE_SUBSTITUTION

This seems to have mythweb working OK. I also had this problem *Mythbuntu 16.04 Fresh Install - always starts MythTV Setup on boot * and found this http://www.gossamer-threads.com/lists/mythtv/users/601385 and this https://ubuntuforums.org/showthread.php?t=2320224 The fix for me was... Short version of solution that worked for me: copy /lib/systemd/system/mythtv-backend.service to /etc/systemd/system/ edit /etc/systemd/system/mythtv-backend.service and insert the line ExecStartPre=/usr/bin/nm-online --quiet --timeout=5 above the existing ExecStartPre=... line. reboot

How to secure Mythweb

Mysql password can be found in /home/mythtv/.mythtv/config.xml When changing password it must be done in the following:- mysql, /etc/mythtv/config.XML and /etc/apache2/sites-available/mythweb.conf and front-end setup.

To change to Schedules Direct grabber:-

0. Back everything up first! 1. Sign up for an account on www.schedulesdirect.org and follow the instructions linked to above to get your 90 day voucher. 2. Activate XMLTV updates repo and update. (I use MythBuntu Control Centre for this. May not be available on other distros) 3. Verify that the Schedules direct JSON module is now a recognised grabber: tv_find_grabbers should find: /usr/bin/tv_grab_sd_json|Schedules Direct JSON API 4. configure your Schedules direct grabber tv_grab_sd_json --configure Follow the on screen prompts. I chose to use a "channels" config, rather than a "lineup" config because I wanted a more fine-grained control over my listings. I don't know whether this is worthwhile or not. YMMV. Our country code is NZL This creates a .conf file in your ~/.xmltv folder I then copied as follows:- sudo cp ~/.xmltv/tv_grab_sd_json.conf ~/.mythtv/SchedulesDirect.xmltv and sudo cp ~/.xmltv/tv_grab_sd_json.conf /home/mythtv/.mythtv/SchedulesDirect.xmltv then edit the cache line in /home/mythtv/.mythtv/SchedulesDirect.xmltv to cache=/home/mythtv/.xmltv/tv_grab_sd_json.cache If the cache line is not edited mythfilldatabase, when run with user mythtv will give error..... FAILED: XMLTV grabber returned error code 13 The name of the xmltv file should match the name of the Video Source that you set up in step 5 below. (e.g. SchedulesDirect.xmltv) 5. Add new video source(s) in mythtv-setup Set the "listings grabber" field to "Schedules Direct JSON API (xmltv)" You also need a unique video source name that matches the symbolic link name that you created in step 4 above. Do not click configure. Do not check the "use EIT" box. 6. Input connections Connect your existing capture cards to the video sources that you just created. You should not need to scan for new channels or do any other configuration here. Do not fetch channels from listing source. 7. Channel editor. You need to enter the

Icons go in the ~/.mythtv/channels folder. It's usually a good idea to empty the /var/cache/mythweb/image_cache/ folder before updating icons.
