tvheadend, ATSC and epg...

I've has issues when installing versions in the past where I couldn't get into the web interface. Unfortunately, I had to uninstall the tvheadend addons...and make sure to delete the userdata files as well. When you uninstall through kodi - it doesn't delete your settings...so you have to do that manually to get a clean install.

Definitely check the epg source list for multiple versions of the same channel first. If there are more than one - select all the versions that have the correct channel number/name. You only need the one that is the "right" one - but it's easiest to select them all for now and see if that gets things working.

Do you mean the channels or just all the user settings?

First - uninstall the addon. In this case just tvheadend...you won't need to delete zap2xml.

Then from windows explorer (the program that looks like a folder icon) Navigate to your network and find your librelec system. Here is a screengrab for reference:

Dropbox - Screengrab network.jpg

Then make your way to the \\LIBREELEC\Userdata\addon_data folder and delete any tvheadend folders. You may have a 4.0 and a 4.2

Then reboot the system...reinstall the tvheadend addon and then you'll have to setup tvheadend again including scanning your muxes...turning off the other grabbers and connecting the zap2xml epg source to the channels.

A little time consuming - but the only way to get a "clean" install. You should only see your favorites in the epg source channel list if zap2xml is setup right with your account.

One more thing - if you want before you do all of this - just navigate to the same folder - and look for the channel folder in tvheadend...then delete the files in that folder - reboot and see if it cleans the list under epg source.

ok - seems strange. Let's confirm a few things...

First - you are running a raspberry pi 3 and libreelec 7.0.2?

You have been able to run and web access tvheadend addon 4.0 but not 4.2 from the LE repository?

What happened when you deleted all the files in the \\LIBREELEC\Userdata\addon_data\service.tvheadend42\channel folder? (likely the 4.0 folder instead)

You have tried uninstalling all versions of the tvheadend addon and then through another computer deleted all tvheadend folders in the \\LIBREELEC\Userdata\addon_data folder?

One thing we can check is what is getting downloaded...it seems from the log that zap2xml is running and pulling data. From your windows computer, go to the following folder \\LIBREELEC\Userdata\addon_data\tools.module.zap2xml

You should see an xmltv.xml file there - open it (it's just a text document so use wordpad) and see if there is program listing in there. The program info will start after the channel listing data, which will be the first set of lines. A program listing will look something like this:

<programme start="20160704120000 -0700" stop="20160704130000 -0700" channel="I25019.labs.zap2it.com">

If that info is not in the xmltv file - then we can target zap2xml. Otherwise we are targeting a tvheadend issue.

The tvheadend versions I have are from CVH's builds. Here is the last version of 4.2 that contained the working list of muxes:

Dropbox - service.tvheadend42-7.0.101-1928.zip

You try uninstalling all versions of tvh, deleting the tvh folders in the userdata folder, reboot and then install this addon. If you install and can't access the web interface let me know and we can target that issue.

No worries - your xmltv.xml file looks great! That means you're getting the data downloaded for the channels you setup on tvguide as favorites.

That means we just need to figure out why tvheadend is not connecting the channel to the epg source data.

If you're now running 7.90.003 that should be a completely clean install of everything (including zap2xml) - unless you did it as an upgrade from the version of 7.0.2 that you were running. Either way - we can walk through the process. Let's work off of 4.2 as it has some better options for forcing the internal grabber to run. If you need to manually enter the muxes (because the predefined list is missing) I'll explain how to do that when you get back to the machine.

Happy to help - it's my goal to get to a point where an affordable dvr is just easy to get running. Unfortunately, most of the people who work on all the software are in Europe - so our messed up US ATSC stuff doesn't get a lot of love. One day the US will get a better OTA tv system...but likely not for awhile!

The versions of tvheadend that I uploaded are only for 7.0-7.02 they don't work on the alpha 7.90 builds. For that - just install from the repository. I'll post the muxes settings in a couple of minutes.

To setup the muxes manually - you need to go to the CONFIGURATION/DVB INPUTS/MUXES tab. This is after you have setup the ATSC network and enabled your TVADAPTER for the ATSC network. Don't worry that you don't have any muxes yet when you create the ATSC network - we'll do that next.

From the MUXES tab, click add - in the popup window select your ATSC network.

The only field you need to change is the frequency line. For each main digital channel you will create a mux. Below I have included a list of all the transmitting stations in your area. I apologize - some of the formatting might be messy in the list. You may not be able to receive them all - but you can start with the channels you know you can receive. So in the list below, you'll see that WUNC channel 4 transmits 4 channels (4.1 4.2 4.3 and 4.4) on digital main channel 25. don't worry about all the . channels. In the second list I have below you'll find the digital transmission channel number, and then the Khz of that frequency. So for digital channel 25 the frequency is 545 Khz.

ATSC frequncies.txt

Now back to our tvheadend mux setup. To setup the mux for digital channel 25 - in the frequency field you'll enter the Khz value but converted to Mhz - so 545 should be entered as 545028000 -- don't ask where the 028 comes from basically just add 028000 to the end of the Khz number.

Once you enter that - save it and it will scan the channel in the background and find the services (which you will setup as the channels)

Repeat this step for each of the digital channels you want to receive and then you'll have all your muxes. Based on your xmltv file you'll setup 7 muxes and the system will then find 19 services that you will map to channels.

This should get you started...once you have channels setup - we'll connect again to see if we can get the guide data in! Good luck!!

Quote from ekincaid

Only 2 of the 7 passed the scan. Double checked the frequencies. Going to have to play around a little more.

which 2?

I apologize - in copying and pasting the frequencies - I moved the numbers in the wrong direction. All the Khz numbers on the list should be 6 lower then what I sent you. My mistake.

Here's an updated list: ATSC frequncies.txt

Sorry about that!
