How do /usr/bin/tv_grabber_* work?

Brent Bolin

I understand they populate xmltv.xml files

The execute as a user hts or other and usually look for .config files if the grabber is enabled

Example:
tv_grab_zz_sdjson.conf (Schedules Direct)
or

.zap2xmlrc (Zap2it)

So the above create or update xmltv.xml files. What happens after that? How does this data get into EPG (ncat file socket ?)

How do other configuration files get created? Example ( /home/hts/.hts/tvheadend/channel/config ) Is this something the grabber does or some other script

If I've updated the xmltv.xml file only how can I get this into EPG. It's my understanding EPG runs in RAM

tvh uses the tv_find_grabbers script which outputs something like..


/path/to/my_grabber|My Grabber Name

If you then setup your grabber & it's shown in the above output tvh will run it & process the output (xmltv) on schedule.

I get that part. So for example if I run /usr/bin/tv_grab_file it will verbose the output of ~/.xmltv/xmltv.xml

If I move xmltv.xml and re-run it fails with:

/usr/bin/tv_grab_file

cat: /home/hts/.xmltv/xmltv.xml: No such file or directory

What happens with all that output? How does it get into the EPG

With the xmltv file moved "wget http://localhost:9981/xmltv" works fine. Also any search in the EPG works fine.

Also epgdb.v2 is a backup of EPG, how does it get there?

Not sure exactly what you are asking.
Did you look in Configuration -> Channel/EPG -> Channels and check the "EPG Source" setting for each channel?

Yes. Since I've used both SD and Zap2it(think I like Zap2it better then the paid subscription to SD) I actually have two options. However SD isn't current

One of my questions is how do these config files get created in "/home/hts/.hts/tvheadend/epggrab/xmltv/channels" and probably others ?

Is this a function of the grabber or does TVH do it. I'm getting the impression TVH does it somehow. Stop/Start/Restart -HUP ?

The other question is how does content get into the EPG

Really like TVH. Tring to get off MythTV setup. It's power hungry and using a large server setup

Currently have TVH running on an Odroid-HC2 and Zoneminder with power to spare. And Odroid-C2's as front ends running Libreelec/Kodi

Sorry if I'm asking a lot of questions. Just trying to get all the little details figured out

The entries in the grabber channels tab come from the grabber, tvh will try and match the data available automatically based on service names.

It's parsed & stored in epgdb.v3/v2. It's read on startup & saved on shutdown or on a timer.
