Μουτσούρες στη webcam

[malos]

Γεια σας. Αγόρασα μία webcam στα 15 ευρώ noname (ή τουλάχιστον, εγώ δεν διέκρινα κάποια μάρκα στο κουτί) και το πρόβλημά μου είναι ότι ενώ δείχνει την εικόνα και με ικανοποιεί η ανάλυσή της συγκριτικά με μία πολύ παλιά που είχα, δείχνει και μουτζούρες στα χρώματα του ουράνιου τόξου.



Αυτά τα ροζ που βλέπετε. Το παραθυράκι που είδατε είναι με την εντολή mplayer tv:// -vf mirror .
Όμως το ίδιο δείχνει και στο zoom.
Είμαι σε ubuntu mate 22.04.

Δοκίμασα και σε kubuntu 23.04 στον ίδιο υπολογιστή και πάλι τα ίδια.

Η κάμερα είναι εντάξει γιατί τη δοκίμασα και σε windows 11 και δείχνει πολύ καθαρά.

Η κάμερα είναι:

Ευχαριστώ.

Καλησπέρα,
Το μικρόφωνο της κάμερας δουλεύει?
Επίσης με την κάμερα συνδεδεμένη, δώσε το αποτέλεσμα :

Κώδικας: Επιλογή όλων

sudo dmesg | grep usb

Το κάνει σε όλες τις θύρες usb του υπολογιστή?

Καλησπέρα και σ' ευχαριστώ.


Στα windows δουλεύει το μικρόφωνο. Στην ubuntu όχι. Το κοίταξα και στο zoom αλλά και στις ρυθμίσεις ήχου όπου επέλεξα για "Είσοδο" την κάμερα. Έχω και ένα φτηνό {άλλο} μικροφωνάκι συνδεδεμένο και δουλεύει αυτό.

Καλημέρα, δοκίμασε να εισάγεις αυτό τον κανόνα για την συσκευή με τις παρακάτω εντολές.
Δημιούργησε ένα αρχείο στην διαδρομή :

Κώδικας: Επιλογή όλων

sudo nano /etc/udev/rules.d/WaveRider.rules

και γράψε μέσα στο αρχείο το παρακάτω :

Κώδικας: Επιλογή όλων

ACTION=="add|change", SUBSYSTEM=="usb", ATTRS{idVendor}=="0c46", ATTRS{idProduct}=="636b", ATTR{power/autosuspend}:="-1", ATTR{power/control}:="on"

κάνε μια επανεκκίνηση, και δες εάν το πρόβλημα παραμένει.
Ο κανόνας αυτός έχει να κάνει με την διαχείριση της ενέργειας στην συσκευή.
Υπάρχει πρόβλημα καθώς η συσκευή δεν στέλει το sample rate και φαίνεται από το dmesg:

Κώδικας: Επιλογή όλων

usb 1-5: 3:1: cannot get freq at ep 0x84
