Das mit -0g habe ich auch probiert, ergibt keine wesentliche Änderung. Was mir auffällt, der Block mit #14 kommt 3 mal vor. Bei mehreren weiteren Versuchen war der Block nur einmal vorhanden, immer mit No locals.

Mal sehen, was der Osterhase so bringt, wünsche schöne Feiertage.

Also liegt das Problem beim RTCP von der Fritzbox.

Geparst wird hier:

vdr-plugin-satip/tuner.c at wirbel · wirbel-at-vdr-portal/vdr-plugin-satip

SAT>IP plugin for the Video Disk Recorder (VDR). Contribute to wirbel-at-vdr-portal/vdr-plugin-satip development by creating an account on GitHub.

github.com

Erwartet wird als Syntax laut SAT>IP spec dort:

ver=1.2;tuner=<feID>,<level>,<lock>,<quality>,<freq>,<bw>,<msys>,<mtype>,<sr>,<c2tft>,<ds>,<plp>,

Die Fritzbox schickt aber einen zusätzlichen Teil dazwischen, der gar nicht in der Syntax für DVB-C enthalten ist, src=1; gilt nur für Sat, nicht für Kabel.

Code

fmtp:33 ver=1.2;src=1;tuner=1,0,1,0,73.00,8,dvbc,256qam,6900,,,,0\na=inactive"...
ps = 0x7fffe77fd6d4 "ver=1.2;src=1;tuner=1,0,1,0,73.00,8,dvbc,256qam,6900,,,,0\na=inactive\n"

Darüber stolpert dann der Parser des strings, der als zweiten Parameter tuner=(..) erwartet.

Ist aber lösbares Problem.

schnuddel · 2. April 2023

also etwa so

wirbel · 2. April 2023

..ganz genau so!

Im Übrigen ist das dann ebenso ein Bug in der fritzbox Firmware.

wirbel · 24. September 2023

Kann mal einer checken, ob diese Änderung in vdr/PLUGINS/src/vdr-plugin-satip/tuner.c:355 das Problem löst?

Code

tuner.c:355

--  if (isSat)
++  if (payload[next].find("src=") == 0)

schnuddel · 25. September 2023

Mein Rechner ist kaputt, muss auf den neuen warten, dann probier ich es gerne. Dauert etwas, sorry.

schnuddel · 7. November 2023

Hallo,

da bin ich wieder.

Code

tuner.c:355


--  if (isSat)
++  if (payload[next].find("src=") == 0)

Den Code verstehe ich nicht. Zeile 355 lautet bei mir jetzt:

Code

if (payload[next].find("src=") == 0)

Zeile 400 lautet:

Code

if (isSat) {

Ich habe ausgeführt:

Keine Ahnung, was das jetzt bedeutet.

Soll ich jetzt noch was machen?

Du hast die Änderung erfolgreich eingepflegt, aber dann

make install

vergessen.

Du hättest das auch ohne Installation ausprobieren können, in dem Ordner wo du make download und make ausgeführt hast.

Aber dann hättest vor den w_scan Befehl einen Punkt und einen Strich setzen müssen, so hast du nur die bekannt fehlerhafte Version erneut getestet.

make install nachholen und noch mal testen.

Klar, da hätte ich auch selbst drauf kommen können.

Jetzt läuft es, prima, vielen Dank erstmal!

Das vollständige Protokoll folgt nach.

Hier ist das Protokoll: protokoll.txt

Die Meldung

ERROR: cannot convert '

a=sendonly

' to integer

stört etwas, weil so häufig, sonst prima!

Das Ergebnis sieht so aus: kanal.txt

FritzBox DVB-C an VDR-SATIP

Jetzt mitmachen!
