ich habe ein großes Problem mit der Kameraüberwachung von meinem Raspberry Pi 4 (Ubuntu MATE 22.04 OS)!
1: Ich habe libcamera erfolgreich installiert und es wird in meinem Ordner und in ls angezeigt, aber ich kann es nicht jedes Mal ausführen, wenn ich es ausführen möchte, wird mir der Fehler „Befehl nicht gefunden“ angezeigt. Ich habe ungefähr 5 Mal versucht, es neu zu installieren!!
2: Wenn ich meinen Befehl zum Starten der Kamera auf meinem Roboter ausführe, wird sie mir bis zum Starten der Kamera angezeigt, aber sie sendet mir kein Bild an meine Entwicklungsmaschine!!

[INFO] [1685308312.026435330] [v4l2_camera]: Starting camera
ich habe die Datei /boot/firmwware/config.txt in camera_auto_detect=0 geändert und start_x=1 hinzugefügt, aber trotzdem wurde die Kamera und alles erkannt, aber wenn ich es starten möchte, läuft es einfach, bis die Kamera gestartet wird, und stoppt und zeigt kein Bild
Bitte, wenn Sie irgendwelche Ideen haben, helfen Sie mir
ich habe versucht libcamera etwa 5 mal neu zu installieren, auch den Treiber und jedes Mal mit dem Treiber funktioniert alles, nur der Start nicht
Traceback vom Terminal: vcgencmd get_camera unterstützt=1 erkannt=1, libcamera-Schnittstellen=0
libcamera-hallo libcamera-hello: Befehl nicht gefunden
