After a bit of a fight, I've managed to get the MIPI camera working on my Lenovo ThinkPad X1 Carbon Gen 10. Here's what I've got:
- I'm using Ubuntu 22.04.3 LTS. - I'm using Kernel 6.2.0-34-generic (with 6.2.0-35-generic for example it doesn't work for me) With the above, I followed these steps: https://wiki.ubuntu.com/Lenovo And I have added these configurations (replacing what is there, if any): - In the file /etc/modprobe.d/v4l2loopback.conf: options v4l2loopback card_label="Intel MIPI Camera" exclusive_caps=1 video_nr=0 - In the /etc/modprobe.d/v4l2-relayd.conf file: options v4l2loopback exclusive_caps=1 card_label="Intel MIPI Camera" - In the /etc/default/v4l2-relayd file: # GStreamer source element name: VIDEOSRC="icamerasrc" #SPLASHSRC="filesrc location=/.../splash.png ! pngdec ! imagefreeze num-buffers=4 ! videoscale ! videoconvert" # Output format, width, height, and frame rate: FORMAT=NV12 WIDTH=1280 HEIGHT=720 FRAMERATE=30/1 # Virtual video device name: CARD_LABEL="Intel MIPI Camera" # Extra options to pass to v4l2-relayd: #EXTRA_OPTS=-d With this, after rebooting the system, the camera usually works in both chrome and firefox (meet, zoom, webcam test, etc...). - In Cheese, I can also get it to work by launching it this way: sudo cheese -d "Intel MIPI Camera". - Sometimes when a black screen appears, just restart the v4l2-relayd service: sudo systemctl restart v4l2-relayd.service I hope this helps someone -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cheese in Ubuntu. https://bugs.launchpad.net/bugs/1978757 Title: Cheese can't playback the preview on Intel IPU6 camera platform Status in OEM Priority Project: Confirmed Status in cheese package in Ubuntu: Confirmed Status in pipewire package in Ubuntu: Confirmed Status in v4l2loopback package in Ubuntu: Confirmed Bug description: Cheese can't playback preview on Intel IPU6 camera platform.
