i followed
multi camera adapter v2.2 manual
But at ‘sudo apt install -y python3-kms++ python3-libcamera’

Some settings may impact device functionality. See link above for details
uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1
uncomment this if your display has a black border of unused pixels visible
and your display can output without overscan
#disable_overscan=1
uncomment the following to adjust overscan. Use positive numbers if console
goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
uncomment to force a console size. By default it will be display’s size minus
overscan.
#framebuffer_width=1280
#framebuffer_height=720
uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
uncomment to force a HDMI mode rather than DVI. This can make audio work in
DMT (computer monitor) modes
#hdmi_drive=2
uncomment to increase signal to HDMI, if you have interference, blanking, or
no display
#config_hdmi_boost=4
uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=spi=on
dtparam=i2c_vc=on
Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18
Additional overlays and parameters are documented /boot/overlays/README
Enable audio (loads snd_bcm2835)
dtparam=audio=on
[pi4]
Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
[all]
#dtoverlay=vc4-fkms-v3d
gpu_mem=256
enable_uart=1
dtoverlay=w1-gpio
start_x=1
#dtoverlay=ov5647
dtoverlay=camera-mux-4port,cam0-ov5647,cam3-ov5647
i connected on A and D port, then ‘libcamera-hello list’ shows two cameras connected.
