[8.0.2c] LibreELEC 8.0 builds for KI Plus / KII Pro / KI Pro

Quote from Hans Gruber

I've just got a KI Pro to replace a Mini MX III with an external USB DVB-T tuner but I'm having a bit of an issue in TVHeadend. The muxes on frequencies 745.833Mhz and 777.833Mhz are failing to scan on the KI Pro, but not on the old box using a "Silicon Labs Si2168" adaptor. If I manually choose 746Mhz and 778Mhz it scans ok but the network discovery thing seems to want to add back the old frequencies. It also seems to be duplicating some of the channels but assigning different channel numbers to them.

Same results with kszaq's 8.1.3 and 8.0.2e releases. I'm in UK using the Tacolneston transmitter (Tacolneston (Norfolk, England) Full Freeview transmitter | UK Free TV 📺). I'm attaching the logs but I'm not sure if they're the right ones, and sorry if my explanation doesn't make much sense! :p

Any ideas?

edit: I think the duplicate channel thing might be unrelated. It seems some channels are being moved around by Freeview.

You can disable network discovery in tvheadend. I verified predefined muxes in tvheadend for Tacolneston, UK and the data are correct. Most likely issue is in weak signal. Try to use antenna with better gain.

P.S.

For fixing issues in tvheadend you have to add log from tvheadend:

/storage/.kodi/userdata/addon_data/service.tvheadend42/service.log

Thanks for the reply. I do have a roof aerial (which I'm pretty much stuck with for now) but do get the occasional glitch on HD signals using the tuner built-in to the TV so there could be some signal issues. I think I'm only about 12 miles from the transmitter with not much in between. Could it be that my old USB tuner is more sensitive and works better with a weaker signal? I could plug the old tuner in but I went for the KI Pro to remove some of the cables hanging out the box. I'll attach my service.log just in case it shows up anything useful/interesting.

Oh also unrelated to this issue I noticed that the HDMI cable supplied with the KI Pro wouldn't supply any CEC data, changing cables fixed it but it seemed a bit odd.

I see from log there are issues only with 745.8 and 777.8. They only use mode DTG-3, all other muxes use DTG-6 or DTG-8. I am sure issue is in weak signal. Changing little bit frequency can improve signal. Most important is SNR. Verify it in tvheadend->Status->Stream for every mux. SNR have to be >25 dB

LE test build with the latest Kodi Leia 18.0-Alpha1 and Nougat kernel (kszaq).

LibreELEC-S905.arm-9.0-devel-201708140759-gb649026-I.img.gz

This build is built for KI Pro, for other S905 device replace dtb (Nougat) in SD.

Installing new addon services is broken. After installing new services (tvheadend, oscam, ...) run vias ssh script 'fixaddonservices' and reboot box.

pvr.hts is already preinstalled you need only enable it.

TVheadend42 in Raybuntu repository is broken use service.tvheadend42-9.0.112e.zip.

You can use this .img for upgrade already prepared SD card putting it to /storage/.update.

If you upgrading from MM version don't forget add Nougat dtb in /storage/.update.

For older TV or DVI connection switch to RGB use following ssh command and reboot box.

echo "echo 'rgb,8bit' > /sys/class/amhdmitx/amhdmitx0/attr" > /storage/.config/autostart.sh

Don't install this version to internal NAND. This is only pre alpha version. There are massive frame skippings UHD fps > 30.

For live debug info use keyboard shortcut Shift-Ctrl-O.

Netflix/Amazon Prime VOD Support

Run the following:

curl -Ls http://nmacleod.com/public/libreelec/getwidevine.sh | bash

Then install one of the following addons:

Netflix addon or install netflix repository from "LibreELEC Addon" repository, and install "netflix" from the netflix repository.

Amazon Prime VOD addon

The tuner does not see my DVB-S tuner, it's just a DVB-T tuner

Have you installed service.tvheadend42-9.0.112e.zip. from zip?

TVheadend from LE repository behaves as you reported above and it doesn't work even for DVB-T.

I can't compare Android driver, there are no sources for it. I use for tuner (Rafael R848) driver from crazycat media_build. Verify parameter for transponders and try to use better LNB.

Hi,

I am using 8.0.1i. Quite old but anyway...

I am trying to scan DVB-T frequencies with w_scan (I have a KII Pro with DVB-S2/T2)

I am running the following command :

w_scan -c MA

But w-scan is not able to get any frequency. Here is what I get :

Code

Same output with 8 Mhz frequencies.

Any idea ?

The way have is done scan in w_scan is unsupported in my driver.

Hi AFL, thanks for your feedback. So what is the prefered way to scan for DVB-T or DVB-T2 channels with your version ?

In Tvheadend select for Network: 'Pre-defined muxes' and for Network discovery: 'New muxes + changed muxes'. Also verify parameters for predefined muxes, for some country this db is outdated.
