Which module do you have? Wonder if have that one…
I’ve used the Pcam 5C: 5 MP Fixed-Focus Color Camera Module - Digilent which is OV5640…
give it at try, mplayer should load it as-is… Beagleplay camera connection - #2 by virtualRadish
Use this overlay: src/arm64/overlays/BPLAY-CSI-ov5640.dts · v5.10.x-ti-unified · BeagleBoard.org / BeagleBoard-DeviceTrees · GitLab
