    Moin,

    habe gerade mein hyperion soweit fertiggestellt, die startanimation läuft problemlos, aber danach flackern ab und zu nur die LEDs, ich habe mal ein Testbild vom Grabber genommen, und ich denke da liegt das Problem:

    jemand eine idee woran es liegt?

    habe max_usb_current=1 gesetzt, und das video signal direkt am tv getestet, funktioniert..

    also wenn du statt in den grabber, das kabel in den TV steckst bekommst du das normale bild angezeigt?
    oder stören dich die weissen punkte?

    Die weißen Punkte sind das einzige was ich vom Grabber erhalte.. Daher kann der Pi auch die LEDs nicht sinnvoll ansteuern.
    Wenn ich das Cinch Kabel vom HDMI2AV Converter direkt in den Fernseher stecke anstatt in den Grabber, wird das Bild Problemlos angezeigt.

    Ich vermute mal der Grabber ist DOA.
    Habe ihn mal zum testen an laptop angeschlossen und mit vlc das gerät geöffnet = black screen

    ich bestell mal den von allen empfohlenen von logilink und teste es damit

    RPi1/Zero
    Es funktioniert jetzt, und es tut mir echt leid für alle die diesen Thread in der Zukunft finden und sich eine Lösung erhoffen, aber ich habe echt keine Ahnung woran es liegt.

    Ich habe jetzt mal meine Pi3B+ platt gemacht und da hyperion drauf installiert, der logilink grabber wird komischerweise nicht erkannt, aber mein 5€ china grabber?!
    Vorher hab ichs mit einem Pi Zero WH probiert, entweder hat der nicht genug Power für den Grabber, oder es funktioniert allgemein nicht mit dem zero..

    Und siehe da, es werde Licht: upload_2019-3-14_0-1-31.png

    Das kann schon gut möglich sein...bei manchen geht es direkt, bei manchen geht es nur wenn sie es statt direkt an den pi, einen extra strom versorgten usb hub nehmen...hatte auch schon das phänomen das der grabber nie ging...1 jahr später aus spass mal probiert gehabt...seit dem geht es ohne probleme...war wohl nicht reif genug :D

    kleine nebenfrage: muss das bild so schlecht aussehen, oder liegt das am 3€ converter?

    ja das ist in ordnung so...ist ja ein analoges signal

    Naja, bei habe ich so viele "falsche Pixel" (gut zu sehen bei schwarzem BIld), dass ich die Farberkennungsschwelle auf mindestens 0.15 setzen muss, da es sonst bei dunklen szenen willkürlich flackert. Ganz weg ist der Effekt bei ~0.17 - 0.18

    das schränkt das ambilight-erlebnis natürlich ein.. :(
