Can't use more than one tuner

Dirk Storck

Hi,
I have a Fritzbox 6490 and setup tvheadend that it uses all 4 tuners wich I can see in tvhead and within my Fritzbox

Fritzbox:

Each tuner has its own ip address assigned.
I have two Kodi in use. If I use kodi on my PC or if I watch Kodi on my cell phone I can watch TV. If I try to watch TV on both Kodi the second Kodi that I start can't get a signal.

I can see in my Fritzbox and tvheadend that it tries to access each tuner but at the end it fails

tvheadend log:

Does anyone has an idea?
Thanks!

Please show the settings of all the tuners. Is there any difference between them? Especially "specinv", spectral inversion or however it's called needs to be set properly for it to work. If tuner 1 is configured different, then only tuner 1 will work. You can also disable tuner 1 to see if then everything is broken or if tuner 2 starts to work then.

Dirk Storck

Where do I find that "specinv" ?

Tuner 1:

Tuner 2:

Tuner 3:

Tuner 4:

Thanks!

Disable "fast input switch", that thing is somehow broken. Have you verified that your server is listening on those IP addresses when it tries to open the stream? Do you have a firewall configured that might be blocking those packets? Can you ping those IPs?

Dirk Storck

I have now disabled "fast input switch"
I don't have a firewall active
How can I check if my server listens on theses IPs? I can ping it on these IPs.

Flole

You can use netstat -tulpn to check. However, you can get rid of the binding completely, for some reason it's not sending from those IP addresses anyways (see your screenshot from the FritzBox, it's all the same IP).

Dirk Storck

What do you mean with " I can get rid of the binding"? Don't I have to assign an IP to each tuner?

Flole

Dirk Storck No you don't need to bind it to different IP addresses IIRC.

Did you run netstat while attempting to stream on the second tuner? Otherwise you might not see anything there.

Dirk Storck

This is the output of "netstat -tulpn"

Dirk Storck

Ok, will have to do that netstat again and remove the binding

Dirk Storck

Thanks a lot! Removing the binding helped! I have tested it on two Kodi and on Plex at the same time and it worked!
