Webgrabplus - Installation for TV headend on Synology

Date: 11-12-2021

Download and installation of WebGrapPlus

Download WebGrabPlus_V3.2_install.tar.gz and upload it to your user directory (/homes/[user])
Start Putty and:

Unzip WebGrabPlus_V3.2_install.tar.gz to your userfolder:tar -zxvf WebGrabPlus_V3.2_install.tar.gz
Navigate to folder .wg++: cd ~/.wg++
Install wg++ with: ./install.sh

The folder .wg++ has a WebGrab++.config.example.xml that needs to bee modified and saved as .wg++/WebGrab++.config.xml

Configure wg++/WebGrab++.config.xml

Open the WebGrab++.config.example.xml and save it as WebGrab++.config.xml
First enable the licence tag: <license wg-username="my_username" registered-email="###@###.com" password="########" />
Set the timespan tag to 7 days
Set the update tag to c
Comment the default dummy channel
On http://webgrabplus.com/epg-channels find the channels that you want to grap and put them in the WebGrab++.config.xml

For test purposes, I use 3 channels from Ziggo

Then the WebGrab++.config.xml looks like this. Upload this to folder .wg++: <?xml version="1.0"?> <settings> <filename>guide.xml</filename> <mode></mode> <postprocess grab="y" run="n">rex</postprocess> <user-agent>Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36 Edg/79.0.309.71</user-agent>  <license wg-username="my_username" registered-email="###@###.com" password="########" /> <logging>on</logging> <retry time-out="5">4</retry> <timespan>7</timespan> <update>c</update>  <channel update="i" site="ziggo.nl" site_id="Nederland 1" xmltv_id="Nederland 1">Nederland 1</channel> <channel update="i" site="ziggo.nl" site_id="Nederland 2" xmltv_id="Nederland 2">Nederland 2</channel> <channel update="i" site="ziggo.nl" site_id="Nederland 3" xmltv_id="Nederland 3">Nederland 3</channel> </settings>
Then in Putty, I run wg++ with: ~/.wg++/run.sh. This is the result:

A guide.xml is created with this content:
<?xml version="1.0" encoding="UTF-8"?> <tv generator-info-name="WebGrab+Plus/w MDB & REX Postprocess -- version V3.2.0.0 -- Jan van Straaten" generator-info-url="http://www.webgrabplus.com"> <channel id="Nederland 1"> <display-name lang="nl">Nederland 1</display-name> <url>http://www.ziggo.nl</url> </channel> <channel id="Nederland 2"> <display-name lang="nl">Nederland 2</display-name> <url>http://www.ziggo.nl</url> </channel> <channel id="Nederland 3"> <display-name lang="nl">Nederland 3</display-name> <url>http://www.ziggo.nl</url> </channel> </tv>

Register wg++ for TVheadend

Login to Putty and switch to root: sudo -i
Download the tv_grab file and save it as /usr/bin/tv_grab_wg++: sudo wget -O /usr/bin/tv_grab_wg++ http://www.webgrabplus.com/sites/default/files/tv_grab_wg.txt
Make the file executable: sudo chmod +x /usr/bin/tv_grab_wg++
Check the grabber and start tv_grab_wg++: tv_grab_wg++: I see the content of guide.xml

TVHeadend configuration

Restart TVheadend
Open TVheadend: under Configuration -> Channel / EPG -> EPG Grabber Modules look for Internal XMLTV: /user/bin/tv_grab_ww++

Activate this Grabber and deacticate all othe grabbers

When I run this grabber by clicking Re-run Internal EPG grabbers, TVheadend logs this:
2021-12-11 10:04:05.772 iptv: m3u parse: 0 new mux(es) in network 'BlackIPTV' (total 35) 2021-12-11 10:05:05.000 xmltv: /usr/bin/tv_grab_wg++: grab /usr/bin/tv_grab_wg++ 2021-12-11 10:05:05.001 spawn: Executing "/usr/bin/tv_grab_wg++" 2021-12-11 10:05:05.006 spawn: cat: /var/packages/tvheadend/target/.wg++/guide.xml: No such file or directory 2021-12-11 10:05:05.006 xmltv: /usr/bin/tv_grab_wg++: no output detected 2021-12-11 10:05:05.006 xmltv: /usr/bin/tv_grab_wg++: grab returned no data

Questions

Should channels been added to the WebGrab++.config.xml?
When I use channels from Ziggo, should the ziggo.nl.ini been added to the to folder .wg++?
Is the WebGrab++.config.xml correct? Is the update tag to c correct?
Is the content of guide.xml correct? Or should it contain all the EPG-data too?
Is the error loadcookie failed! ... cannot update this channel causing problems?
Why is TVheadend looking for a file in /var/packages/tvheadend/target/.wg++/guide.xml: No such file or directory?
