TVH only allowing some streams via external middleware

I have three adapters on my server but getting the error below. what is causing the "no free adapter" or " no input source" 2024-05-09 07:50:00.482 subsc...

There is very little information about how your system is configured.

Browse to http://{TVH-IP}:9981 and go into configuration.

Check that your adapters are visible to TVH.
Also check that your adapters are associated with the network(s) configured on your system.
Go into the status screen and see if any tasks are holding these adapters open.

Bossman

Thanks for the reply, they are all visible

I think there are associated, base on when I'm changing channels the signal strength switch to different adapters.
3.My middle-ware is constantly pulling streams (but only streams up to 12 maxed out at 16 before errors starts.
I found 96 services and 84 of them have been mapped, TVH would not let me stream more that 16 for some reason. when I probe the channel it doesn't connect but if I restart tvh from he command line and probe the same channel, its connects and disconnect a connected channel.
I've been at this for three weeks researching and finding stuff that help with some errors but the cap on streaming and no adapters or input issue. do you do remote services, I have vnc on my server maybe you can take a look and see where im messing up or missing.

It's interesting that when you run TVH manually, you get different results.

What command line options did you use manually?
How does TVH normally start?
Do you know the command line options used?

You can try ps aux|grep tvheadend to look for the command line options used to launch TVH.

I'm running from the snap store

`$ snap restart tvheadend
snap start or stop tvheadend

I know how to do screenshots, I was on my cellphone responding, That's why it was phone pics lol

Bossman

Im doing one at a timer instead of mass start, this is 9 streams and all adapters are occupied ![

So I figured out something. If my middle-ware run a batch start stream and one of the channels has an error, tvh freaks out and stop starting streams. It will only start the same stream if you restart tvh via command line. Now by doing it one by one i was able to start 26 channels manually vs batch and only getting 12. Im getting the errors in the pasted log below, what is causing this and can it be fixed?

DeltaMikeCharlie

I am out of ideas at the moment. Sorry.

Bossman

DeltaMikeCharlie quick question, do you know how many streams a card can stream to clients? I want to know because I'm planning on having a lot of clients.

DeltaMikeCharlie

Bossman I don't know, I'm sorry. However, It's probably not related directly to the card.

I'm not sure if TVH limits the number of streams, but it could come down to the way the OS is configured and/or the throughput of your network.

Each card may contain 1 or more tuners and each of those tuners will be able to access 1 mux at a time. Each mux can have multiple services.

So if you have 1 card, you can only stream from 1 mux, but if your clients are all using services from the same mux, then your limiting factor could be the capacity of your network. I recommend experimenting to see what your network can tolerate.

Bossman

DeltaMikeCharlie Okay, So I bought another server.I have a quad turner card also bought another 13 single cards, so far one server will have 9 turners. (quad plus 5 singles)
Question

When scanning for muxes, is it limited by the amount of cards installed or type? Reason I'm asking, when I only had the quad it only found 4, but when I added more it found 10.
2.Can Musxes be assign to individual cards?
3.

DeltaMikeCharlie

Bossman Can Muxes be assign to individual cards?

Yes, sort of.

You need to create separate networks.

Ensure that the card(s) that you want to restrict are only assigned to that network. Create the muxes that you want assigned to specific a specific card(s) on the network that has that card(s) attached.

Bossman

DeltaMikeCharlie Question is tvheadend limited to the amount of tuners, I have 12 but 9 install? Ubuntu sees them all if I use "lspci" command but when I open headend it only see 8

DeltaMikeCharlie

Bossman Question is tvheadend limited to the amount of tuners

A quick look suggests 32.

tvheadend/tvheadendblob/d2e41b553e7cc6eb06fd21b42bbed4b3a1f28bc0/src/input/mpegts/linuxdvb/linuxdvb_adapter.c#L390

Enable debug/trace to see what TVH reports regarding adapters.

It looks like TVH searches for /dev/dvb/adapter0 to /dev/dvb/adapter31 do your adapters follow this pattern?

Bossman

DeltaMikeCharlie sorry for the late response, been working out of town a lot. when I get back I will check it out. thanks

Bossman

@DeltaMikeCharlie !

I don't know if this is significant, but I noticed that you are using a snap package. Could it be possible that snap is somehow limiting the devices that are available to TVH?

Perhaps you could report this issue to the publisher of the snap package.

You could also try enabling debug/trace for the linuxdvb subsystem and see what messages you get.

Im trying to install TVH outside the snap-stor and i'm getting this error. what dependencies i'm I missing. I want to see if its the snap stop version with the limitations.

DeltaMikeCharlie

Bossman what dependencies i'm I missing.

Try asking the publisher of the Snap package.
