Heyho,
ich habe nach allen Anleitungen, die ich gefunden habe, meinen PI konfiguriert.
Aktuell habe ich OSMC drauf und mit dem internen framegrabber von hyperion funktioniert alles wunderbar.
Nun habe ich mir den Mumbi Grabber zugelegt und wollte damit starten, mein TV Signal abzufangen. Ich habe die Screenshot (+Crop) Funktion ausgeführt, bis die schwarzen Balken weg waren.
Auf den ersten Blick funktioniert auch alles. Zwischendurch wechselt die Farbe jedoch schlagartig (meistens) auf blau (ohne dass überwiegend blau vorhanden ist) und anschließend wieder in eine korrekte Farbe.
Ich habe nur eine Lichterkette und nicht die einzelnen LEDs konfiguriert.
Die Besonderheit ist, dass es eine HUE LED-Kette ist. Aber mit dem framegrabber funktioniert ja alles so, wie es soll.

Ich frage mich jetzt, was das Problem ist.
Ach eine Sache ist mir noch aufgefallen - beim Screenshot erhalte ich immer so einen pinken Rand (siehe Screenshot), den ich nicht per Crop wegkriege.
Bei dem normalen Framegrabber musste ich HUE-spezifisch 5.0 Hz angeben, weil höhere Werte wohl Schwierigkeiten verursachen. Fehlt vielleicht so etwas für den Mumbi Grabber?
Hat jemand eine Idee?
Meine Konfiguration nochnmal:
- Mumbi Grabber direkt am PI (Pi 1, Modell B+)
- keine weiteren USB Geräte am PI
- TV -> Scart Adapter -> Cinchkabel -> Mumbi Grabber
- OSMC aktueller RC
