octopus: "RTSP/1.0 455 Method Not Valid in This State" followed by vdr crash

[heinz045]

Hi,
I'm using a digital devices octopus (V1.1.6) with vdr-2.5.6 and satip-plugin 2.4.1. Frontend is Kodi 19.3.
Only using free tv channels everything runs smoothly. Using one of the two cam slots, e.g. viewing ORF1 HD (pid=1920) or recording it, it works.
But when I simultaneously start recording (or viewing) e.g. ORF2 III HD (pid=3080) (of course I do have 2 cam modules with ORF cards) I'm getting a "455 Method Not Valid in This State" error on the log file. 30 seconds later vdr crashes, as well as kodi.
Attached is the journal-log and the wireshark streams.

At 12:03:00 the recording of ORF1 HD is started
At 12:04:01 the recording of ORFIII HD is started
At 12:04:04 error 455 occurs (line 186 of journal.log)
At 12:04:35 the ORF1 HD Recording shows 750 errors
At 12:04:35 (line 209 of journal.log) "ERROR: video data stream broken" following with an emergency exit.

I'm not sure that the 455 error is involved in the crash problem, but at least it should not happen. I guess the combination of addpids and x_pmt (line 102 of recording2_tcp_stream.txt) in one request is not allowed on the octopus.

I'd be very grateful for any hints how to analyze further.
Thanks,
Heinz
