DVB-T2 (HEVC, H.265) with LibreELEC (ODROID C2, Raspberry PI 3)

    Ich musste die SD-Karte wechseln und finde keine Sender mehr. Ich kann bei "Fourth "Vordefinierte Muxe zuweisen"

    Suggestion: generic all" genau dieses nicht auswählen. Habe nur Generic-auto, ganz viele Länder, auch Germany mit den ganzen Regionen. Wenn ich nun Germany Berlin auswähle und dann auf DVBT2 die Muxes ändere findet er trotzdem nichts, bzw. der Scan ergibt einfach nur einen Fehler.. Hat jemand vielleicht die Einstellungen für Bandbeite Constellation Transmission Guard Hierarchy etc. damit ich die manuell hinzufügen kann?

    Danke!

    twokay: ich verstehe nicht wirklich was nicht funktioniert ...

    Raspberry PI 3



    Same configuration like with ODROID C2 but with this changes


    LibreELEC v8.0.1.MR


    .


    Test


    Before v8.0.1 MR while playing DVB-T2 top showed


    - Load is high ("load average: 4.38", should presumably be below 4 on the 4 core ARM CPU of the Raspi)


    - CPU utilization near 90% (see %Cpu0..3 .") but there are also still idle times "8.1 id to 10.5 id"


    - SD card mass storage seems to be no bottleneck as no wait IOs can be seen "0.0 wa"


    - also memory seems to be sufficient "326940 free" and no swapping "0 total"


    .


    With v8.0.1 MR this changed to


    - Load is lower ("load average: 3.60", should presumably be below 4 on the 4 core ARM CPU of the Raspi)


    - CPU utilization about 50% (see %Cpu0..3 .") and respective idle times "~40 id"


    - SD card and memory unchanged.


    - Main Processor temperatur is mostly above 80°C and below 85°C

    Deprecated Stuff


    Bluetooth keyboard (apple)


    Keyboard is needed to get wifi connection running, to avoid timeout [Error: Invalid arguments] with WPA key input. As no wifi is available on ODROID C2 and also bluetooth is missing this is not an issue.

    Danke, genau das meinte ich! Wenn ich alles auf Auto habe, findet er den ZDF Mux nicht, der ARD-Mux ging jetzt nach dem 50-sten Mal. Anscheinend ist bei mir, obwohl direkt in Berlin, das DVBT2 Signal sehr schlecht. Würde also gerne die Sender händisch eingeben mit den ganzen Werten, weil gibt ja nur die 2 unverschlüsselten Muxe.

    I followed the instruction of Melibokus and it worked out very well for me :)

    To avoid issues with DVB-T2-stick I did lots of researches, to find out which one is available (affordable) and which one is supported by Libreelec. Finally I purchased a Geniatech T230C (~30 €) which worked out of the box with Wrxtasy's Media Build Edition.

    As I connected a 2.5" HD-Drive and a DVD/Blu Ray Drive I have to use an external powered USB-hub. I experimented with direct connection to Odroid but it did not work.

    Thanks for this really helpful and very comprehensive instruction :thumbup:

    Hi there,

    thanks for your great work, I want to set up my Odroid C2 with August T210 stick exactly like you wrote it.

    Unfortunately I'm stuck with getting tvheadend server and client as raybuntus repo is somehow ... down. I already tried to use repository.kodinerds.zip from raybuntus CoreELEC repo, but it doesn't work.

    Is there a way to get tvheadend server and client?

    Any suggestions highly welcomed.

    Hi Mickey450,

    unfortunately I was not working on oerlie project intensively in the last months and am not up to date with solutions for the ODROID TV-stick driver topic.

    My current working solution uses the latest Raspberry PI 3 B+ as tvheadend server, where the USB stick runs out of the box. ODROID is only the tvheadend client in order to have its hvec decoding capability available. By the way due to lates improvements in libreelec software and Raspberry PI 3 B+ increased computing power a configuration with Raspberry PI 3 B+ only is near to day2day useabilty. Last remaining problem is some judder (ger: ruckeln) eg. with landscape pans (Landschaftschwenks, d.h. bei schnellen Bildbewegungen, auf deutsch wär's doch einfacher:-).

    Zurzeit plane ich wieder tiefer einzusteigen, wenn libereelec 9 bereit ist. Auf dem Raspi migriere ich gerade dahin (kämpfe aber noch mit IPTV).

    I currently plan to proceed with the project when libereelec 9 is available. I moved to libreelec 9 alpha 8.90.6 on Raspi, but struggle with IPTV implementation.

    Currently I work on the migration of my installation to libreelec 9 alpha, where some rework on the former IPTV pipe solution is needed, as ffmpeg which was available with libreelec 8 directory /usr/bin is currently not available with libreelec 9 alpha (but probably in future as mentioned in this post by CvH) .

    My solution is inspiered on the kodinerds m3u lists and uses the ffmpeg binary from ffmpeg-tools addon as suggested by CvH below. Two commands have to by issued on command line interface:

    • cd ~/downloads
    • wget http://bit.ly/kn-pipe-tv
    • sed s/usr/'storage\/.kodi\/addons\/tools.ffmpeg-tools'/g kn-pipe-tv >kn-pipe-tv-adapted

    Finally add/change in tvheadend IPTV server configuration (port 9981) under

    • >Configuration>DVB Inputs>Networks>[network] Edit>
    • URL: file:///storage/downloads/kn-pipe-tv-adapted

    In addition a configuration hint as I assumed today (after switch to winter time last night) some time trouble.

    Time server is configured with libreelec configuration using the service of the Physiskalisch-Technische-Bundesanstalt:

    • >Einstellungen/Configuration>Libreeelec>Einstellungen>Netzwerk>Zeitserver (NTP)
    • Erster Zeitserver: ptbtime1.ptb.de
    • Zweiter Zeitserver: ptbtime2.ptb.de
    • Dritter Zeitserver: ptbtime3.ptb.de

    Quote from CvH

    that isn't working anymore, you need the ffmpeg-tools addon + change the path to that

    ... oops, you are right - but the description above does already consider the ffmpe-tools addon. So I changed the hint concerning the "Emby addon".

    Just recently, I tried to upgrade my system - which I installed with exactly this instruction - to Libreelec 8.2. Unfortunately I lost support of my DVB-T2-Stick (Geniatech T230C) and I did not get it working.

    Which approach would you recommend to enable Geniatech T230C in a more recent Version of Libreelec?

    Edited once, last by Fasterix (December 10, 2018 at 8:09 PM).

    As latest test with the two usb sticks described above, Odroid and "standard" LibreELEC 8.95 failed, this is my suggestion for a workaround with IPTV.

    .

    Besonderheiten:

    • Vollständige LibreElec/Kodi Konfiguration von Null.
    • Reproduzierbare Programmreihenfolge (im Server, durch entsprechnde Reigenfolge in der m3u-Datei)
    • Kodi Kontextmenü über rote Fernbedienungstaste aktivieren.
    • Keine EPG :(
    • Der Forums-Editor lässt die englischen Wörter für Gesundheit und Schönheit nicht durch. Deshalb musste ich zwei Programme aus der Liste unten "maskieren". Vor Übernahme (Kopieren/Einfügen) wieder richtig schreiben (x-en weglassen).

    Die Beschreibung ist diesmal auf deutsch und hier zum sequentiellen abarbeiten bzw. kopieren eingefügt.

    .

    Legende:

    • Zeilen die mit # beginnen sind Kommentare bzw enthalten Anweisungen für Aktionen auf der graphischen Benutzeroberfläche von Kodi bzw. TvHeadend.
    • Alle anderen Zeilen enthalten Befehle die 1:1 kopiert und in die Kommandozeile eines Terminals eingefügt werden, um abgearbeitet zu werden. Ggf. muss der jeweilige Befehl durch Eingabe von <enter> abgeschlossen werden.
    • Mehrere aufeinanderfolgende Zeilen ohne # werden en bloc kopiert und in die Kommandozeile des Terminals eingefügt. Ggf. muss der jeweilige Befehl durch Eingabe von <enter> abgeschlossen werden.
    • Das kopieren von Zeilen mit # in das Terminal ist unschädlich.
