Description

Similar to Ticket #6041 I also have 'parent disabled' services, but here in combination with SAT>IP client
TVH is 4.3-1967~geb59284b8.
Changing Maximum PIDs from 32 to 20 lets me map some more channels, but lots of them stay "parent disabled".
Restarting TVH and rescanning (initial scan) many times also brought me a few more channels that where mapable.
My equipment: SAT>IP-Server (SATPI) on E2-Box with 8x FBC DVB-C-Tuner. When I activate DVB-C tuners on box for direct reception all transponders have good results for SNR (almost every t has 90%), AGC (every t has under 60%) and every t has BER 0. Direct TV reception als well as SAT>IP transmission to other SAT>IP-Client (other E2-Box) is without image- and sound disturbances. SAT>IP-Client on other E2-Box finds all channels.

I reproduced same issues on 2 different setups. 1st is Ubuntu Workstation x64-20.04 LTS on VirtualBox client on Win10 x64 host and 2nd is Ubuntu Server x64-20.04 LTS on VMware vm
On both setups tvh was installed via

sudo add-apt-repository 'deb https://apt.tvheadend.org/unstable bionic main' 
I always used standard configuration. Excpections: 'Maximum PIDs' 32 (standard) is down to 20, 'pass specinv' is on and 'network discovery' is 'new muxes and changed muxes'

When some channels can be found tvh logs

2021-07-19 14:46:14.322 mpegts: 546MHz in Vodafone-E2 scan complete

2021-07-19 14:46:14.322 subscription: 052B: "scan" unsubscribing

But a lot of channels cannot be mapped, they stay 'parent disabled"

When no channels can be found tvh logs

2021-07-19 14:48:31.522 mpegts: 594MHz in Vodafone-E2 - tuning on SAT>IP DVB-C Tuner #6 ([email protected])

2021-07-19 14:48:31.522 subscription: 0537: "scan" subscribing to mux "594MHz", weight: 6, adapter: "SAT>IP DVB-C Tuner #6 ([email protected])", network: "Vodafone-E2", service: "Raw PID Subscription" 

2021-07-19 14:48:36.521 mpegts: 594MHz in Vodafone-E2 - scan no data, failed

A similar procedure to "Restarting TVH and rescanning (initial scan) many times" is to reset failed muxes to scan status 'ACTIVE'. This also brought a few mapable channels at the begining of my channel search.

Thanks for help

Are there any transport errors or continuity errors?

I just looked at this again:

Your server is simply not providing data to Tvheadend, so Tvheadend does exactly what it is supposed to do: Detect that the frequency is unavailable and disable it. Not a Tvheadend bug most likely, unless you can show that the data is actually sent to Tvheadend and it doesn't pick it up (which is possible but unlikely).

Errors are neglectible: only a few every two hours

I think, SAT>IP-client of Tvheadend behaves buggy, because other SAT>IP-client (other E2-Box) is able to find all channels and receive streams without errors from SAT>IP-server.

To proof that behaviour, I would like to publish here detailed log of SAT>IP-server (SatPI) and at the same time (same time slot) detailed log of tvheadend. Please tell me which debug parameters to choose in order to catch precious information. Thank you

Logs alone won't help, what would be needed is a capture of the traffic with the log, if there's no traffic after Tvheadend sent a request then it's not a Tvheadend issue.

Wireshark?

Yes, Wireshark could be used for that.
