Ich kann den Patch in seinem jetzigen Zustand mal hier einstellen.

Leider nimmt das manuelle Testen ziemlich viel Zeit in Anspruch.

@putschi
welche basis hast du genommen? oscam-v11725 und icam-v9/v8 ???
und da du die uno4kse und solo2 erwähntest, gehe ich von ready2arm und ready2mips32el aus?

putschi · 3. Oktober 2023

11725 + emu + v9
ready2arm und ready2mips32el? was meinst du damit?

Token · 5. Oktober 2023

@putschi
naja, du erwähntest in deinen Threads beide Box-Typen.
daraus schlussfolgere ich, das der "buffer.patch" entsprechend auch für beide CPU-Architekturen geeignet ist?

putschi · 6. Oktober 2023

Ja, habs auch auf der Solo 2 mal ein wenig getestet. Sollte funktionieren.

Hab mal ein wenig aufgeräumt. Ist aber noch mehr rauszuschmeißen.

Wäre auch wünschenswert den sender_thread wieder zu entfernen. Ist auch noch ein relikt aus ersten Versuchen. Bringt unnötig Komplexität hinein.

Mir ist leider noch immer nicht wirklich klar, wieso das notwendig ist. Interessant fand ich noch, dass der v9-Patch auf der VU+ Uno 4K SE gut funktioniert, wenn man den Transportstream inkl. ECMs von der SF8008 abholt. Es hängt also wohl wirklich mit dem Burst/Buffer Verhalten zusammen (2100 Packets alle ~100-900ms).

ChrisOsgood · 6. Oktober 2023

Im Allgemeinen stell ich mich zwar nicht so an, aber der Patch funktioniert bei mir nicht.

Was ist denn die Voraussetzung? Emu+V9+Buffer?

putschi · 6. Oktober 2023

Das patchen funktioniert nicht? Hatte etwas weiter oben geschrieben, was ich als Basis genutzt habe. Kann es später aber auch nochmal kontrollieren

weiß gerade nur nicht, wo ich den oscam-emu.patch für 11725 bezogen habe. ich meine das war im streamboard

Die für 11725 gabs hier nicht glaube nicht. 11724 war die letzte soweit ich weiss. Und die für 11725, die habe ich auch vom streamboard.

Womit baust du denn? Mit s3 bekomme ich die gleichen Fehler wie @ChrisOsgood
Die Zeilen der Änderungen passen irgendwie nicht. Habs bei ein paar Hunks geändert aber wurde mir dann doch zu viel alles zu checken und ändern

Baue auch mit s3 (./s3 solo4k). Gepatcht habe ich allerdings manuell. Habe das oscam-svn Verzeichnis in s3 ausgetauscht. Nutze s3 nur, da es der schnellste Weg zu den Toolchains war.

Bauen mache ich auch mit s3. Mit s3 svn auschecken und dann händisch über die console patchen und dann mit s3 bauen.

Code:

patch -p0 < oscam-emu.patch
patch -p1 < oscam_emu_icam_dvbapi_radegast_v9.patch
patch -p1 < buffer.patch

Alle patches ohne Fehler nur der buffer.patch spuckt die ganzen Hunks usw. aus.
