Hi Leute

Ich versuche auf einem RPi4 die MLD 5.5 Testing zusammen mit Telekom Magenta-TV (IPTV) an meinem DSL Anschluss zum Laufen zu bringen.
Wer hat mit dieser Kombination schon Erfahrungen gesammelt? Bei mir ist selbst mit SD Kanälen kein flüssigen Bild zu erreichen. Bei HD sieht es noch schlechter aus.
Bei SD gibt es für ca 2 Sekunden ein Bewegtbild, dann stockt es für ca. 5-10 Sekunden und wiederholt sich danach. Die CPU Last liegt bei ca. 85-95%. Das meiste geht dabei auf den vlc Prozess zur Konvertierung des IPTV.

Im /var/log/vdr sehe ich dabei nach einem Restart des VDR folgendes:

Ist der Rpi4 mit Softhddevice eventuell zu schwach, dass IPTV flüssig anzeigen zu können? Oder welche Tricks gibt es eventuell noch zum Ausprobieren?

Hi,

Welcome

I think pulseaudio package for RPI4 is broken,
I had to repack pulseaudio debian package to make it work.

Have you tried alsa instead?

I dunno about libvlc error, you have vlc installed?

Best Regards

[sturmmoewe]

Hi gr4vity

Thanks for your warm welcome and your quick reply.

Yes, vlc is installed. Searching for the given packages shows

How do I switch from PulseAudio to Alsa (using the MLD web config)? Within the MLD sound configuration I can't see any selection for Alsa or PulseAudio. Can you please point me to the right config steps to give it a try? Thanks.

Regards
Ulf

[gr4vity]

Hello sturmmoewe,

From command line, do as follows:
apt update
apt remove pulseaudio
apt install alsa

Then see if it works, if not then you can wait for Claus to fix pulseaudio package.

Best Regards.

[sturmmoewe]

Gr4vity,

Thanks again. PulseAudio is not installed, only libpulse0. And on the other side Alsa is already installed.

Wir benutzen bei der MLD kein Pulsaudio. Da dran kann es also nicht liegen.

[gr4vity]

Hi sturmmoewe,

According to the following line, i see that your system is trying to use pulseaudio.
vlcpulse audio output error: PulseAudio server connection failure: Connection refused.

After reading your 1st post again.
This scenario is strange to me.
You use vlc to convert iptv channels then use Softhddevice to watch it?

It's not possible to use kodi simple iptv client instead?
I don't have much experience with vdr iptv plugins though.

It should be some other direct way to watch iptv channels without using 90% CPU consumption.
That will surely cause your problem.

Best Regards.

[sturmmoewe]

Hi gr4vity

You use vlc to convert iptv channels then use Softhddevice to watch it?

Not intentionally. I just installed the MLD 5.5 Testing for rpi4 with the selection IPTV and EPGdata and the rest was a "default" installation from MLD. I did not select to install Kodi. Maybe this cloud be the error?

[gr4vity]

Hi sturmmoewe,

Well, i'm really sorry i have never tested MLD IPTV installation.
I dunno which vdr plugin plugin you are using.
However, vlc should not be involved in such scenario.
Please wait for someone else who have experience with IPTV MLD installation.

Kodi simple iptv client is another option if you want to try it later.

Best Regards.

[sturmmoewe]

Hi gr4vity

Thanks for your support. At the moment I started another MLD installation where I also install kodi.
We'll see. 

[gr4vity]

Hi sturmmoewe,

I noticed that you haven't posted any feedback,
According to this thread by mldnonexpert, Kodi doesn't work either.
https://www.minidvblinux.de/forum/index.php?topic=10274.msg81702#msg81702
You said we'll see but apparently you didn't see anything ... right? 

Best Regards.

[sturmmoewe]

Hi gr4vity

Sorry for coming back so late due to lack of testing time caused by my job 

I tried setting up MLD 5.5 Testing with Kodi and also tried gstreamer instead of softhddevice.
But with no combination I got any working environment. All I got was a blank X screen with no application at all. Kodi did not work neither using softhddevice nor gstreamer and VDR also didn't come up when choosing gstreamer instead of softhddevice at installation. On the rpi4 I only the combination VDR with softhddevice at install works (with the discussed problems).
So I'm still searching for other other test cases to try out with MLD and rpi4 ro get Magenta IPTV working.
Or maybe the rpi4 really lacks resources for my special usecase.

Best Regards,

[BobW]

Hi sturmmoewe,

some 5 years ago I set up an IPTV-VDR using A1-Telekom's IPTV services (Austria). Contrary to the channels.conf offered by MLD I found that no ffmpeg was required and no additional scripts werde needed. Just vdr-plugin-iptv and a fitting channels.conf. Here is an example:

The addresses needed I got from the Internet. The parameters for the channel entries were/are listed in the documentations.
In my case the only caveat was the missing EPG, none at all. That could be remedied with an external source.
This machine was running for more than a year without any problems

Maybe this can help you getting on with your project.

Kind regards

[gr4vity]

Hi sturmmoewe,
Thanks for the feedback,
I think you don't need to install a lot of combinations to make it work 
You only need Kodi with PVR IPTV simple client enabled.




As you can see in screenshot, you only need m3u playlist to make it work.

You can do the same thing with VLC.
The problem is you need to have hardware acceleration enabled to lower the CPU consumption.

I asked Claus to build Kodi with hardware acceleration but he didn't reply yet.

I have no idea if it's enabled in VLC or not.

Softhddevice will not work by itself, you need to enable an IPTV plugin to make it work.

Best Regards.

[sturmmoewe]

Frohe Weihnachten nachträglich an alle.

Es gibt positive Neuigkeiten. Die Ruckler beim IPTV kommen durch die dazwischengeschaltete vlc2iptv Instanz. Wenn die IPTV Kanalliste per .m3u in eine channlens.conf konvertiert wird, sieht beispielsweise der Eintrag für "Das Erste HD" wie folgt aus:

Code: [Select]

(1) Das Erste HD;IPTV|T-Entertain_M3U:1:S=0|P=0|F=EXT|U=vlc2iptv|A=1:I:0:256=27:257=deu@4;258=AC3@106:2321:0:28106:0:0:0
Die .m3u Datei enthält die diesen Sender den Eintrag:

Code: [Select]

#EXTINF:-1,(1) Das Erste HD
rtp://87.141.215.251@232.0.20.35:10000
In einem älteren Backup habe ich eine Version einer (auf einem andere VDR System) in der Vergangenheit funktionierenden IPTV channels.conf gefunden. Dort sieht die Zeile für "Das Erste HD" dagegen wie folgt aus:

Code: [Select]

Das Erste HD;IPTV:23500:S=1|P=0|F=UDP|U=87.141.215.251@232.0.20.35|A=10000:I:0:256=27:258=deu@3;257=deu@106:259:1A:10301:1:10301:0
Hier wird kein vlc2iptv dazwischengeschaltet. Dieser Stream läuft auch auf dem RPi4 flüssig. Allerdings ist diese ältere channels.conf so alt, dass nicht mehr alle Streams gültig sind. Ich suche jetzt einen Weg, aus der (von der Fritzbox) ladbaren .m3u Senderliste eine funktionierende channels.conf ohne das vlc2iptv erzeugen zu können.
Falls hier jemand von euch Tipps hat freue ich mich.

Euch allen einen guten Rutsch.
