Failed to play hidden services

Description
I have scanned a frequency that has certain channels that emit only sometimes, all of them work properly except two (M.LCAMPEON5 and M.LCAMPEON6). When I play them, it tells me that the service is not enabled (I have not touched any box) and if I map it to a channel, it tells me that the adapter is not available.
However with other players as an enigma the channel does work when it emits. Here never.
What I see in the tbl-base traces being different from the rest of services is this:
2019-02-14 20:02:34.693 [ TRACE]:tbl-base: sdt: type 01 (1) name [M.LCAMPEON6] provider [Movistar+] def_auth [] 2019-02-14 20:02:34.693 [ TRACE]:tbl-base: sdt: type changed / old 01 (1) 2019-02-14 20:02:34.693 [ TRACE]:tbl-base: sdt: name changed 2019-02-14 20:02:34.693 [ TRACE]:tbl-base: sdt: provider changed
old? this is a service scan after deleting both services (!)
P.S.: Attached full log

This bug is terribly random

Did you grab the logs when the service is broadcasted? There should be PMT scan:

I see it. It looks like PID subscription problem. The PMT PIDs >= 1049 are not subscribed from the tuner.

So is it a SAT>IP tuner problem?

Am I wrong or TVH is not requesting these PIDs?
Updated by Jaroslav Kysela over 6 years ago
TVH limits the concurrent PIDs to the configured value (see the client config - it's usually 32), but it should unsubscribe and subscribe the another group during the scan. Unfortunately, something prevents to do this in your setup. I just did a quick test for 19.2E 12363V and it works good here (the PMT PIDs are splitted):

I have PID limit set at 64. Maybe these PID limit is partially applied?
I mean, in normal retransmissions 64 PIDs can be used, but in the case of scans this is hard limited to 32 (25) - no splits and no more pids ?

Nevermind. I see it in the code, you extended the PID limit, but it cannot be stored to the 127 characters per request and the current implementation in satip_rtsp_play() is a bit dumb, so the additional PIDs are just silently stripped. Try to extend also the maximum length of PIDs (twice).

You are right. When increasing PID lenght it works.
Is this a definitive solution? We should increase the PID lenght for the satip triax and kathrein in that case (device/firmware-specific workarounds).

I hope that this is fixed for all configs now. The split method was improved and it is more universal now.
